By Kenn Garder Content originally published in February of 2016. Purchasing a house is a major decision, and a home inspection report can be used to assist in the decision-making process. Here are some of the more common issues found during a home inspection. Poor Grading and Drainage Water should run away from any structure to help prevent moisture intrusion. If the soil around a house slopes toward the house, or if water pools around the perimeter of the foundation, that moisture can create hydronic pressure in the soil that can move the foundation, causing cracks and leaks that can lead to extensive damage and expensive repairs. If water wicks into the wood framing members, the wood will rot over time. This moisture also provides a haven for wood-destroying organisms (WDO) because it provides a water and food source. Erosion around the perimeter of a house may be caused by water spilling over gutters due to clogged downspouts or downspouts that terminate near the foundation. Downspout extensions or spill ways can be installed to keep water away from the foundation. Roof Coverings The roof of a house is designed to withstand most of what Mother Nature can dish out, whether it be rain, wind or sun. If installed properly, the roof should keep water out of the home. The life expectancy for roof coverings varies depending on the material. Asphalt composite shingles, for instance, typically have a life expectancy of 15 to 25 years. As the roof covering ages, it can become more susceptible to water infiltration and leaking. Plumbing Problems Notice a theme here? Controlling water is one of the most important issues in home maintenance. Leaking supply water and drain lines can cause damage to walls and floors, or they can become the water source for mold and mildew. Outdated (galvanized) or problematic systems (polybutylene) can develop leaks more frequently. Wax rings under toilets can develop leaks and damage the floor around the toilet or the ceiling below. Electrical Issues House fires caused by faulty wiring and overloading circuits are common. It is not unusual for a home inspector find evidence of DIY additions to a home’s electrical system. Many times these additions work but were not done properly, causing safety issues. Exposed wire connections and double taps in the panel are also common problems. If your home inspector finds these or other electrical issues, he/she will recommend that you have the system evaluated and repaired by a qualified licensed electrician. HVAC Havoc Inadequate maintenance of the HVAC equipment is common. Dirty condenser coils on the air conditioner condenser unit and dirty furnace filters can lead to major repairs. The equipment may be at or near its life expectancy and need to be replaced. Gas-fired furnaces may not burn properly. With proper maintenance, an HVAC system can continue to heat and cool the house, but many times heating and cooling systems are “out of sight out of mind.” This is a sampling of typical issues found during a home inspection. These items may vary depending on the geographical location of the property and the overall maintenance of the property. Looking for a professional, qualified home inspector in your area?
