When house problems arise, water is often the culprit

The American Society of Home Inspectors has polled its membership to ascertain the most common problems found with houses nationwide. Although some of the issues we find in Georgia are consistent with the rest of the nation, North Georgia has its own set of unique problems.

The following is a list of five of the most common problems based upon both the ASHI research and my personal experience, accompanied by suggestions for avoiding them. I’ll detail additional problems and solutions in next week’s column.

1. Water intrusion into basement and crawl spaces: Without question, water entry into under-floor spaces is the No. 1 problem I find in metro Atlanta homes. Water intrusion is significant because it can result in additional problems, including foundation failures and mold growth. The causes of the water intrusion are varied but usually include improper channeling of ground and roof water away from the house. To avoid this problem make sure that gutters and downspouts are kept clean at all times. If this is not enough to solve the problem, consider changing the grades around your house to slope more drastically away from the structure. If neither of these solutions works, consider consultation with a qualified waterproofing contractor.

2. Water heaters: I have never performed a statistical analysis, but I would bet that 60 percent to 70 percent of the water heaters I inspect are improperly installed. Like foundation problems, incorrectly installed water heaters can result in additional problems ranging from leaking to explosion of the heater. Unless you are qualified, I recommend having water heaters installed by licensed plumbers. Although it may not eliminate problems, it should considerably reduce the chances of improper installation.

3. Poor exterior maintenance: Failure of the homeowner to properly maintain exterior caulk and paint results in decayed wood siding and trim. Depending upon the extent of the decay, repairs can be expensive. This one is simple. At least twice a year, in the fall and spring, examine the exterior of your house for peeling paint and loose or missing caulk. Periodic maintenance of these areas will go a long way toward avoiding expensive repairs and should result in some energy savings as well.

4. Electrical: Electrical problems are especially prevalent in older homes where homeowners or unknowledgeable handymen have made additions or alterations to electrical components. Improperly installed electrical systems can result in shock and/or fire. Current and past codes are precise as to proper methods for installing electrical systems. Electrical work should always be performed by a licensed electrician. Although rarely done, it is a good idea to have your electrical system examined by a licensed electrician every five years. We tend to assume that our electrical systems will function indefinitely without maintenance. Unfortunately, this is not true and the result of electrical problems can be serious.

5. General plumbing: Many people do not understand that improperly installed plumbing can be a health hazard. Improperly installed supply, drain or vent piping can result in poor or inadequate operation of the plumbing system. Drain water that is allowed to infect the potable (drinkable) water system can have serious health consequences. Many minor plumbing repairs can be made by homeowners. More complex plumbing problems, however, are best addressed by a licensed plumber to ensure that unhealthy conditions don’t result.
