• Spiff up the front entry. One way to stay on top of your home's maintenance and protect your investment is to look at it as though you're a stranger considering it for purchase. Perform repairs as the need arises and try each year to add a little to the home's attractiveness on the outside. One good way to boost curb appeal, as real-estate agents call it, is to make the entrance more appealing. Once the weather is dry, check steps, decks and porches for wood rot and peeling paint. Repaint porch steps and railings yearly with durable deck paint. Wash winter grime and dust off the front door and door frame. Repaint or stain the front door to protect wood doors and give the whole home a little face lift. Consider using a fun accent color such as barn red, black, hunter green, navy blue or gold, depending on the other colors on your home's exterior. You may want to add built-in planters to a deck or front porch and change the plants with the season.
• Check for roof dams. Now that the worst of the weather is behind us, pull a ladder up to the roof to check the valleys and remove accumulations of sticks, leaves, tree needles and other storm debris. Similar to the dangers posed by melting snow on a roof, dammed-up debris can let moisture penetrate the roofing and reach into structural timbers and walls, causing rot and mold. Also, check the flashings, or metal seals, around roof joints, chimneys, skylights and other structures that penetrate a roof for holes or rust. Make repairs or call a professional.
• Check for water under the house. While spring rains are still falling, or shortly after, get beneath the house to see if there's any accumulated water. It should be dry there, even when it's raining outside. If not, first eliminate the possibility of leaks from inside the house by checking the underside of the floor for dripping water or water stains. Track down any plumbing leaks and repair them or call a plumber. If an inside leak is not to blame, look next for seepage from outside the house. Check where the foundation meets the ground for spots where the earth slopes toward the house. Even dirt mounded around shrubs should be corrected by replanting. Fix any sloping earth so that it directs water away from the house. If you live at the bottom of a hill, that may mean calling a drainage expert to diagnose problems or help devise solutions. Keep up preventive maintenance by trimming trees and shrubs to keep them from touching the house and channeling water down the walls; remove ladders, wheelbarrows and other equipment stacked against the outside of your home. Install extensions on gutter downspouts to keep water far from the structure.
• Book a home inspector. The only time most folks meet a home inspector is during the sale of their home. But by then, you're learning about troubles too late. To stay on top of your home's maintenance and head off expensive repairs, hire a home inspector to scrutinize your home from top to bottom. Cost: $200 to $400. (Read "4 tips for finding the best home inspector.") Tag along on the inspection so you can see any problems for yourself and learn about your home by asking questions. The inspection will give you either peace of mind that everything's in good shape or a list of chores to be done. Ask the inspector to help you prioritize the repairs.
Now move indoors to complete your moisture-detective tour and perform some other TLC. Banish household smells • Clean the garbage disposal. It's good to get in the habit of doing this monthly. Pour a cup of vinegar into an ice cube tray, fill up the rest of the tray with water and stick it in the freezer. When the solution has frozen, pop out the vinegar ice cubes and place them in the disposal. Turn it on and let the ice cubes scrub the disposal as they are ground up. The vinegar will remove accumulated grease and eliminate odors coming from the disposal. Clean all drains, including the disposal, two or three times a year by pouring in equal parts salt, baking soda and vinegar, followed about 30 seconds later by two quarts of boiling water. Give the mixture a chance to work overnight to clear clogged drains. (Learn more: "Drains 101: Skip the plumber and tackle these tasks yourself.")
• Clean or replace garbage cans and pails. Check garbage containers inside and out for cracks and breakage. Replace cracked or broken outdoor cans and use bungee cords to keep lids closed tightly. Take the kitchen garbage pail outside, sprinkle in a half-cup of baking soda and fill the can with hot water. Let sit for an hour, then dump out the water and use spray cleanser to wipe down the can inside and out. Dry it thoroughly before putting it back in the kitchen and inserting an empty garbage bag. Clean the refrigerator by removing everything and washing down the inside with hot water and baking soda.
• Eliminate bathroom and kitchen smells. Trapped moisture encourages smelly mildew, mold and rot, which can create odors in the kitchen, laundry and bathrooms. Thoroughly inspect each of these rooms for cracks and breakage in grout and caulking that let water seep behind tile and flooring.
• Check appliances for plumbing leaks. Look for moisture under or around sinks, tubs, washer, dryer, shower and toilets. Check for toilet leaks: Add a few drops of food coloring into the tank (not the bowl) of a toilet. Don't flush. Come back in an hour to see if any of the color has reached the toilet bowl. If it has, you probably need to replace the flapper in the tank. If water is collecting around the base of the toilet, the seal - the wax gasket between the toilet and floor - may have failed and need to be replaced.
• Inspect and repair drywall. Once a year, walk around the interior of your home with a spatula and container of lightweight putty (ask at the hardware store for help choosing products). Inspect the walls for dings, nail holes and gouges. Use the spatula to smooth putty into holes and scrape the repaired spot even with the wall. Return the next day and touch the putty to see if it has dried. Once dry, gently rub it with fine-grained sandpaper so the patch will be smooth and even with the wall. Gently retouch the spot with primer, then with paint. If a repainted area shows up when dry, you may have to repaint the entire wall.
