Welcome to Rocky's Corner. It's time to give your home a little TLC. We all know how quickly time flies -weeks turn to months and months to years. Too often homeowners neglect to do periodic maintenance checks on building structures, roof systems, household fixtures and appliances. This neglect can lead to expensive repair costs that could have been avoidable.

You have joined me on the first of an 8-part series on Preventative Maintenance Tips for your Home. I hope that you will find this information to be both informative as well as useful in helping you to maintain your home.

PREVENTATIVE MAINTENANCE TIPS FOR YOUR HOME MONTHLY FIRE EXTINGISHER:
* Check that it is fully charged and recharge if necessary.

SMOKE DETECTORS AND CARBON MONOXIDE DETECTORS:
* Test all alarms to insure that they are working properly.

GARBAGE DISPOSAL:
* Always run cold water when grinding to harden fats and grease and to move waste down the drain lines.
* Disposers are generally self-cleaning- grinding citrus peels, eggshells, small bones, or a little ice will clean deposits and get rid of odors.
* Remember not to grind oyster or clam sheels, or highly fibrous materials or non-organic materials such as metal, glass or plastic.

DRAINS:
* Use a non-toxic biological drain cleaner regularly to keep drains clear. (Avoid using bleach or mouthwash down biologically treated drains because it kills the "friendly bacteria" working to keep your drains clear.

SINKS & TUBS:
* Check for moisture or small leaks under toilets, bathtubs and sinks.
* Keep strainers in your bathroom sinks to catch soap pieces and hair.
* Overflow holes on tubs should always be clear to prevent water damage to floors and ceilings.
* Flush with hot water and baking soda.

HEAT PUMP:
* Clean reusable filters or replace disposable.

FORCED WARM AIR HEATING SYSTEM:
* Clean reusable filters or replace disposable.

EVAPORATIVE AIR CONDITIONER:
* Clean reuseable filters or replace disposable.
* Clean evaporator or condenser coils.
* Clean condensate drain when in use
* Clear debris from around outside unit.

When performing your maintenance check if you should find that additional work is required consider hiring a professional. Proper care and maintenance to your home can saves hundreds of dollars in repair costs. I hope that you have found this article to be helpful and informative.

Myth: Assessed value should equate to market value.
Reality: While most states support the concept that assessed value approximate estimated market value, this often is not the case. Examples include when interior remodeling has occurred and the assessor is unaware of the improvements, or when properties in the vicinity have not been reassessed for an extended period.

Myth: The appraised value of a property will vary, depending upon whether the appraisal is conducted for the buyer or the seller.
Reality: The appraiser has no vested interest in the outcome of the appraisal and should render services with independence, objectivity and impartiality - no matter for whom the appraisal is conducted.

Myth: Market value should approximate replacement cost.
Reality: Market value is based on what a willing buyer likely would pay a willing seller for a particular property, with neither being under pressure to buy or sell. Replacement cost is the dollar amount required to reconstruct a property in-kind.

Myth: Appraisers use a formula, such as a specific price per square foot, to figure out the value of a home.
Reality: Appraisers make a detailed analysis of all factors pertaining to the value of a home including its location, condition, size, proximity to facilities and recent sale prices of comparable properties.

Myth: In a robust economy - when the sales prices of homes in a given area are reported to be rising by a particular percentage - the value of individual properties in the area can be expected to appreciate by that same percentage.
Reality: Value appreciation of a specific property must be determined on an individualized basis, factoring in data on comparable properties and other relevant considerations. This is true in good times as well as bad.

Myth: You generally can tell what a property is worth simply by looking at the outside.
Reality: Property value is determined by a number of factors, including location, condition, improvements, amenities, and market trends.

Myth: Because consumers pay for appraisals when applying for loans to purchase or refinance real estate, they own their appraisal.
Reality: The appraisal is, in fact, legally owned by the lender - unless the lender "releases its interest" in the document. However, consumers must be given a copy of the appraisal report, upon written request, under the Equal Credit Opportunity Act.

Myth: Consumers need not be concerned with what is in the appraisal document so long as it satisfies the needs of their lending institution.
Reality: Only if consumers read a copy of their appraisal can they double-check its accuracy and question the result. Also, it makes a valuable record for future reference, containing useful and often-revealing information - including the legal and physical description of the property, square footage measurements, list of comparable properties in the neighborhood, neighborhood description and a narrative of current real-estate activity and/or market trends in the vicinity.

Myth: Appraisers are hired only to estimate real estate property values in property sales involving mortgage-lending transactions.
Reality: Depending upon their qualifications and designations, appraisers can and do provide a variety of services, including advice for estate planning, dispute resolution, zoning and tax assessment review and cost/benefit analysis.

Myth: An Appraisal is the same as a home inspection.
Reality: An Appraisal does not serve the same purpose as an inspection. The Appraiser forms an opinion of value in the Appraisal process and resulting report. A home inspector determines the condition of the home and its major components and reports these findings.

Garden (noun): a) plot of ground where herbs, fruits, flowers, or vegetables are cultivated b) a rich well-cultivated region c) a container (as a window box) planted with usually a variety of small plants [Merriam-Webster Online]. As seen in the preceding definition, gardens can be functional providing herbs & veggies or they can be landscaped areas of beauty with flowers and other cultivated plants. Whether for an apartment with window boxes and porch containers or a house with acres to play, everyone can create a garden if they want one. There are many wonderful resources online that can help those who want to add plants around their home environment.

First we collected some good, free, online landscaping planners that help you plot out your yard and garden before you plant a single seed. Most come with some plant information but we have also collected a list of plant reference sites that detail plant climate preferences, light requirements and much more. Finally, we have listed sites that offer ideas for unique and complex garden solutions or not so common alternatives to liven up your bit of green.

Part I:

Planning Your Garden Masterpiece Part of the fun of gardening or landscaping a home are the random finds at the local nursery. Ooh! That hasta is beautiful and would look great next to my window! Never mind the poor sage that now gets no light and begins to wither away! Granted this doesn't always happen and not everyone has the time (or the budget) to pre-plan and selectively purchase everything for their yard at one time. However, free online landscaping tools are easy to use and are a fun way to get a little more structure to your garden before you start tossing dirt around. Most of these planners are ideal for large scale sketches. Once the big picture is sketched out, you can more easily concentrate on the smaller parts of the project. It is easy to become overwhelmed by all the plant choices and concepts you may like to try around your home. Having a plan eases the work of the anxious gardner working towards a larger masterpiece. Better Homes & Gardens Plan-a-Garden www.bhg.com Website: Plan-a-Garden lets you design anything from a patio-side container garden to your whole yard. Use your mouse to "drag-and-drop" more than 150 trees, shrubs, and flowers. Add dozens of structures like buildings, sheds, fences, decks -- even a pond. Homecheck Review: You must sign up for online membership to access, but it is free. Opening quick tips offers the only tutorial. Plants are more ‘cartoonish’ which makes it easier to draw out spaces but doesn't help the plant-challenged who may not know what the heck a real Heuchera looks like! There is a option for more plant info that offers info about temperatures and growth height; but very basic at best. I do really like the drag-and-drop with the mouse to place objects. Also easy rotation, zooming and hiding controls. Don’t forget to save your garden; one perk to having an online account is that you may save work on projects and come back to them later. gardenplanner www.smallblueprinter.com/garden/ Website: Arrange plants, trees, buildings and objects using an easy to use 'drag and drop' interface. Use tools to quickly create paving, paths and fences. Then produce a high quality color print out of your design. Homecheck Review: This is a paid program but there is a free trial version you may download to your computer or try online.This program is very basic with both objects and their shapes. This is a better concept planner where you can draw out what you want the yard to look like and then fill in plant details later. Program itself is easy to use, just click drag and click you objects wherever you want. Homestore.com The Garden Designer www.homestore.com/homegarden/gardening/tools/landscapeplanner/ Website: Homestore.com's Garden Designer is the easiest way to visualize the perfect outdoor design! Homecheck Review: There is a simple introduction to the program that gives information by answering common questions. There is no membership requirement to use this program. Like the others it includes a drag and drop interface. Objects are easy to size. Although plants are again clip art, they do offer more variation in look so it is easier to distinguish which plants you place on your grid. However, no information about plant lighting, size and other details are provided. Quick and easy to use, just have a good idea of your plants ahead of time. Lowe's Landscape & Garden Planner www.lowes.com Website: If your outdoor inspiration needs a little help, here is the tool you need. Use Lowe's Landscape and Garden Planner to help build the yard of your dreams. With our design tool, garden and landscape planning are as easy as clicking and dragging. Homecheck Review: This site does request user registration to use freebies. It offers free online newsletters at the time of registration and you can opt out if you choose. Once in the Planner there is a great opening tutorial - turn on your speakers as it is narrated! This program is easy to use with a point-and-click and drag-and-drop tools. When you begin your layout you will be prompted for width and depth of the lot and your region on the US climate map. Hardscapes or objects like your home, driveway and fence are basic images. Plants are listed by sun requirement and type. Plant pictures are basic drawings rather than real images which is not as fun to plan with for those of us with less plant knowledge. Nice features include the sectioning off of areas on the plan so you may work on smaller plots one at a time and printable shopping lists of of your design. NOTE: I used this site the first time a couple of months ago (1/05) and LOVED it, great detail and real images of plants! Recently when I reviewed it again (6/05) it was too simplistic and buggy - many of the radio buttons brought up 0 options to choose from when I logged in the first two times; at the third log-in things started working. And now cookie-cutter-clipart plants rather than images of the real thing? What were they thinking? Blah! Not sure what happened to this once awesome program? Still good and easy to use but not as stellar as before.

Part II:

Plant Reference Sites Solanum Tuberosum? I just wanted a potato... Sometimes the most frustrating or overwhelming aspect of planning your yard can be finding the right plants. Knowing your climate zone is only the first part of the battle. A plant's happiness in your yard will depend on sun exposure, watering, soil make up and all other types of fussy tid bits.Then there is the not so obvious questions of what will the plant look like in 5-10 years. Having a good book to flip through is a good start. The power of the internet is that you have the ability to refine searches and find new hardier plants that may not have been originally strong enough for your region. Below are some online plant guides that can help demystify the abundant world of flora. BBC Gardening Plant Finder www.bbc.co.uk/gardening/plants/plant_finder/ Website: Look up detailed information about thousands of plants using our searchable database. You will find descriptions of the plants and tips about growing them. Homecheck Review: Okay, we know it is not local and there are certain quirks - using centimeters instead of inches!? But seriously, this is an easy to use database. The pictures are great and there are good short plant bios. Burpee www.burpee.com Website: The Burpee company was founded in Philadelphia in 1876 by an 18 year-old with a passion for plants and animals and a mother willing to lend him $1000 dollars of "seed money" to get started in business. Within 25 years he had developed the largest, most progressive seed company in America. By 1915 we were mailing a million catalogues a year to America's gardeners. Homecheck Review: Granted this is a site interested in selling products. But the garden wizard is easy to use and full of good information and pictures. A nice feature is the ability to describe what type plant you need: sun, sow, height and difficulty. The search results come with pictures that may be selected for more detail. This was an easy tool for getting information about vegetable garden plants. Again, due to the fact that they are limited to products they sell not every plant out there will be available for search. Dave's Garden http://davesgarden.com/pf/ Website: Welcome to PlantFiles, the largest plant database in the world with 101,549 entries, 76,918 images and 45,373 comments. Currently entries are from 350 families, 3,587 genera, 22,207 species, and 68,483 cultivars. PF continues to grow through the collaborative efforts of 11,388 gardeners from around the world, most notably the Uber Gardeners. Any registered user may add new plants, images, details, comments, and ZIP codes. Homecheck Review: Finally a database worth checking out! Easy to search, great pictures, and great information about how to sow, grow and maintain the individual plants. An extra plus is that visitors may post comments about their experiences growing the plants listed. HortiPlex Database from Garden Web www.gardenweb.com Website: The HortiPlex database contains plant images and data as well as links to information sources, images and vendors at other sites. Searches may be limited to: just those records with images or links to images; records with vendor links; or, records of botanical taxa. Homecheck Review: Some of the plants listed have information in the actual database which is provided users who leave remarks and pictures. For the most part this database lists other listings out there that reference a particular plant. It is bare bones and somewhat difficult as it is not at first obvious where to click for more information. Disappointing in that most plants only have links to other databases. Would be much better if more users participated and left remarks about the plants they have used or know about. GreenPlace.com (Part of Home & Garden Showplace) www.gardenplace.com Website: Need gardening information and inspiration? Help is just a click away. Homecheck Review: Number of plants are limited to the more common variety. Probably based on what the store carries as well. Easy to use search - really like the show everything option. Nice pictures of the plants. Information for the individual plants is basic, similar to what you would find on the the plant tag at the store. Home Depot Plant Guide www.plant-guide.com/HomeDepotForm.asp Website: Get the information you need to design your garden like a pro. Find out which plants are right for your landscaping project or learn about a particular plant you purchased at Home Depot. Homecheck Review: This site is easy to use. I find doing a broad search by climate and plant category to give the most results. When doing a search like this the results can be substantial (in the hundreds!). Results include list of scientific and common names. Clicking on selection takes you to a more detailed description that includes pictures, scale, uses and much more. For an online freebie, I really liked the usability of this tool. Martha Stewart Living www.marthastewart.com Website: Finding plants for your garden is as easy as picking the features that are most important to you. For instance, for plants that attract butterflies, check that box and your Zone, and click on Search. Homecheck Review: The plant search is very detailed. You may also want to browse by plant type if you are still in the broader planning stage. Pictures are good, usually of the plant feature, flower or fruit). The detail about the plants is wonderful. Definitely a great resource about most plants out there. Another fun addition to this planner is the ability to search plants by 'theme gardens'. Great lists and good way to plan various sections of your yard. Plants Database http://plants.usda.gov/index.html Website: The PLANTS Database provides standardized information about the vascular plants, mosses, liverworts, hornworts, and lichens of the U.S. and its territories. It includes names, plant symbols, checklists, distributional data, species abstracts, characteristics, images, plant links, references, crop information, and automated tools. PLANTS reduces costs by minimizing duplication and making information exchange possible across agencies and disciplines. Homecheck Review: It is not the easiest to browse this database. However, if you know what particular plant you are looking for it is probably in here. Plant information is more scientific. Some plants have pics and some do not. Best for general information about your plants but not necessary a gardening tool. Rock Garden Database www.kadel.cz/flora/kvSearch.html Website: Welcome to the Rock Garden Plants Database. It contains 11253 species with 560 photos and is still growing. For each plant you will find here known synonyms of its name, short description, territory and altitude of its natural location, size, color, bloom, if it is calciphile (Ca+) or calciphobe (Ca-), its type (rosette etc.), cultivation and propagation. Homecheck Review: This site is specialized but has some fun information. Not easy to search but fun to browse. A work in progress shows but still information about plants that aren't as common. MORE SEARCHING... Check out local nursery websites as well. Many of these sites list their plants with pictures and all kinds of good information. Plants will be limited to their selection, but it is another fun way to browse the possibilities. Part III: Unique & Complex Garden Solutions Rooftop need a bit of green?

Q Our home inspector reported that three windows in our 9 year old house had fogging insulated panes, and he suggested that we contact the builder or manufacturer for warranty information. We contacted the manufacturer who sent a man out, but he said that only two of the windows were fogged. When we called the inspector, he said that insulated windows will fog only under certain conditions, and that we look at the windows at the same time of day that they were inspected. Is our inspector a bit foggy in the head?

A It has been my experience that insulated window panes, when the seal is broken, will fog only under certain conditions. The two pieces of glass in a double-pane window have an inert gas between them which is held in place by a seal. This thin space of gas is what allows the windows to slow down the transmission of heat or cold. When this seal is compromised, ordinary air is allowed to enter, and moisture may condense on the inside surfaces of the glass. These types of windows are most likely to fog on a winter morning a short time after the sun hits them. The outside of the window has been cold overnight, and the inside has been warm. When the sun hits the cold outer glass, moisture condenses and the foggy appearance occurs. A few hours later, as the temperatures stabilize, the fog may disappear altogether. In this case, the inspector was correct to suggest that the windows be inspected under the same conditions. In the case of your 9 year old house, your windows may still be under warranty. The earlier versions of insulated windows were somewhat prone to failure, but technology has steadily improved, and today’s windows are much more reliable. Warranties have gotten much better as well, so it you have foggy windows, check with the manufacturer to see if you can have them replaced under warranty.

Imagine leaving a window open all winter long -- the heat loss, cold drafts and wasted energy! If your home has a folding attic stair, fireplace or clothes dryer, that may be just what is occurring in your home every day. These often overlooked sources of heat loss and air leakage can cause heat to pour out and the cold outside air to rush in -- costing you higher heating bills. Air leaks are the largest source of heating and cooling loss in the home. Air leaks occur through the small cracks around doors, windows, pipes, etc. Most homeowners are well aware of the benefits caulk and weatherstripping provide to minimize heat loss and cold drafts. But what can you do about the four largest “holes” in your home -- the folding attic stair, the whole house fan, the fireplace and the clothes dryer? Here are some tips and techniques that can easily, quickly and inexpensively seal and insulate these holes. Attic Stairs When attic stairs are installed, a large hole (approximately 10 square feet) is created in your ceiling. The ceiling and insulation that were there have to be removed, leaving only a thin, unsealed, sheet of plywood. Your attic space is ventilated directly to the outdoors. In the winter, the attic space can be very cold, and in the summer it can be very hot. And what is separating your conditioned house from your unconditioned attic? That thin sheet of plywood. Often a gap can be observed around the perimeter of the door. Try this yourself: at night, turn on the attic light and shut the attic stairway door -- do you see any light coming through? These are gaps add up to a large opening where your heated/cooled air leaks out 24 hours a day. This is like leaving a window open all year round. An easy, low-cost solution to this problem is to add an attic stair cover. An attic stair cover provides an air seal, reducing the air leaks. Add the desired amount of insulation over the cover to restore the insulation removed from the ceiling. Whole House Fans Much like attic stairs above, when whole house fans are installed, a large hole (up to 16 square feet or larger) is created in your ceiling. The ceiling and insulation that were there have to be removed, leaving only leaky ceiling shutter between the house and the outdoors. An easy, low-cost solution to this problem is to add a whole house fan cover. Installed from the attic side, the whole house fan cover is invisible. Cover the fan to reduce heating and air-conditioning loss, remove it when use of the fan is desired. If attic access is inconvenient, a ceiling shutter cover is another option for reducing heat loss through the ceiling shutter. Made from R-8, textured, thin, white flexible insulation, and installed from the house side over the ceiling shutter with Velcro, a whole house fan shutter cover is easily installed and removed. Fireplaces Sixty-five percent, or approximately 100 million homes in North America are constructed with wood or gas burning fireplaces. Unfortunately there are negative side effects that the fireplace brings to a home especially during the winter home-heating season. Fireplaces are energy losers. Researchers have studied this to determine the amount of heat loss through an unlit fireplace, and the results are amazing. One recent research study showed that an open damper on an unlit fireplace in a well-insulated house can raise overall heating-energy consumption by 30 percent. This is truly a remarkable statistic! A recent study showed that for many consumers, their heating bills may be more than $500 higher per winter due to the air leakage and wasted energy caused by fireplaces. Why does a home with a fireplace have higher heating bills? It is simple - hot air rises. Your heated air leaks out any exit it can find, and when your heated air is drawn out of your home, cold outside air is drawn in to make up for it. The fireplace is like a giant straw sucking the heated air from your house! An easy, low-cost solution to this problem is to install a fireplace draftstopper. Available from Battic Door, a company known for their energy conservation products, a fireplace draftstopper is an inflatable pillow that is installed into the fireplace below the damper. As the pillow is inflated, it seals the damper, eliminating any air leaks and heat loss. Other benefits include the reduction of downdrafts, toxins, odors, pollutants, and noise. The pillow is removed whenever the fireplace is used, then reinserted after. Completely reusable and available in two sizes to fit any masonry or zero-clearance fireplace, the draftstopper can pay for itself in less than a month! Clothes Dryer Exhaust Ducts In many homes, the room with the clothes dryer is the coldest room in the house. Your clothes dryer is connected to an exhaust duct that is open to the outdoors. In the winter, cold air leaks in through the duct, through your dryer and into your house. Dryer vents use a sheet-metal flapper to try to reduce this air leakage. This is very primitive technology that does not provide a positive seal to stop the air leakage. Compounding the problem is that over time, lint clogs the flapper valve causing it to stay open, or a cold breeze can blow the flapper open, allowing frigid air right to come right into the house. An easy, low-cost solution to this problem is to add a dryer vent seal. This low-cost, easily installed vent is mounted on the outside of your house, and reduces unwanted air infiltration, and keeps out pests, bees and rodents as well. The vent will remain closed unless the dryer is in use. When the dryer is in use, a floating shuttle rises to allow warm air, lint and moisture to escape. If your home has a folding attic stair, a whole house fan, a fireplace, and/or a clothes dryer, you can easily, quickly and inexpensively seal and insulate these holes. At Battic Door Energy Conservation Products, we have developed solutions to these and other energy-conservation related issues.

Q Our home inspector recommended that we install a chimney cap on the older home that we are buying. The chimney has not had a cap in it’s 60 plus year life, so why put one on now?

A In my practice as a home inspector, I always recommend the installation of chimney caps. Chimney caps serve a variety of purposes. They keep animals such as birds, squirrels and rodents from entering the chimney and in some cases the crawl space. A 60 year old home may have had an oil-fired furnace in the crawl space or basement which would have been vented through the chimney. The vent pipe opening provides direct access for critters. It is not unusual for rodents to crawl down through the chimney into the crawlspace seeking a warm place to nest. Chimney caps also keep out rain and debris such as leaves that can collect in the flu. Chimney caps also serve as spark arresters. Most caps are not expensive, and your local chimney sweep can recommend the one that is best for your chimney.
