Do an Annual Walk-around Home Check, and Don’t Forget the Windows and Doors

“It is important to periodically monitor the overall condition of a home,” says John Ghent, president of the American Society of Home Inspectors, a non-profit professional organization for home inspectors. “Simple wear and tear from weather and age occurs in every home. It is wise to fix any problems before they lead to extensive and costly repairs.”

Your inspection should include all of the major systems that protect your home, including the windows, doors, roof, gutters, exterior finish, foundation, and steps; plus the interior systems such as heating, cooling, chimney, and electrical, says Pella Corporation’s Gary Mathes, manager, residential architectural services. Look for obvious signs of deterioration, damage or potential problems. Check for conditions that may allow moisture to enter your home -- from plants and sprinkler systems too close to the house to low-lying areas that direct water toward the home. Likewise, watch for any deteriorating wood, cracks, damaged caulk, old weather stripping, and other potential sources of leaks, says Mathes.

The following 10 items cover common maintenance issues with windows and doors and should be included in your walk-around check:

1. Inspect the interior and exterior finishes around windows and doors. Is the paint or stain in good condition? Signs of flaking and peeling may mean that it’s time to refinish the unit.

2. Look closely at all exterior surfaces for cracking, deteriorated wood and other damage that might be caused by condensation or other water penetration. Are any interior surfaces such as walls, floors or ceilings discolored or showing the effects of moisture?

3. If you spot a problem, try to find its source. For example, discolored wood around a window might actually be caused by moisture entering the house some distance away. With a roof leak, for example, it is not uncommon for water to run down the inside of the wall and show up at the window. Contact an expert to obtain help if needed.

4. Check window sills and tracks for dirt and other debris such as sand, leaves, insects, and pine needles. Open the windows and clean out the area with a soft brush. Do the same for sliding patio doors. Debris can hamper the air-tight effectiveness and overall performance of doors and windows.

5. Feel for uneven sliding and sticking when you open and close a window or door. If windows or doors stick, try using a non-oily lubricant on the opposing finishes, such as Paraffin wax, which does not attract as much dust and grime.

6. Look at the weather stripping around all doors and windows. Re-attach any loose portions and replace portions that are ripped or torn.

7. Operate locking mechanisms and make adjustments if they feel loose or don’t work smoothly. Locks not only help keep out potential intruders, but they hold doors and windows tightly in place to lock out rain, wind, snow, and insects.

8. Inspect any weep holes and breather holes if your windows or sliding patio doors have them. Weep holes allow excess moisture to escape and breather holes allow air exchange within certain components. Clear blocked holes with a small wire, toothpick or similar device, being careful not to expand the holes.

9. Check all exterior sealants and caulking on and around all windows and doors. Pay particular attention to areas susceptible to punishment from rain, water and extreme sunlight. Remove damaged material and reapply sealant.

10. In coastal locations, rinse all exterior metal components and cladding to minimize the corrosive effects of salt spray and fog damage. This should be done at least quarterly.
