Foundation and Structural Issues
Due to their age, older homes should be inspected thoroughly for foundational and structural damage. Cracks or unevenness in the foundation can lead to moisture damage, dry rot, corrosion, and shifting of the house. According to Safewise, “Foundation repairs can escalate to over $10,000, depending on the extent of the structural issues – and homeowners insurance won’t cover these costs.” If you suspect structural damage, be sure to have the building inspected by a licensed structural engineer.
Electrical and Plumbing Issues
Many older homes have their original plumbing and wiring, as updating these systems can be costly. Keeping the original knob-and-tube wiring or the original cast-iron pipes, however, can be a serious safety hazard. Old electrical systems can cause a fire, and old pipes can cause leaks or weak water pressure.
The older a home is, the more likely it is to contain hazardous materials, such as asbestos and lead. Lead is commonly found in paint applied before 1978 and in plumbing installed before 1985. Asbestos can be found in gas fireplaces, roofing, and insulation that was installed before 1980.
Outdated Heating and Cooling Systems
Older homes were likely designed for oil, coal or wood heating systems and later retrofitted with newer HVAC systems, so it’s important to understand when and how these upgrades were made. Even a more up-to-date heating system can be inefficient and unsafe if it hasn’t been maintained properly.
Houses with cooling systems are likely to be a bit newer, but outdated cooling systems are known to have their own issues. Common problems with older AC units include improperly working fans, reduced efficiency, refrigerant leaks, and electrical problems.
Termites and Bugs
Depending on where the home is located, termites and other bugs could be a major issue. The National Pest Management Association claims that termites alone cause around $5 billion in property damage yearly. The older the home, the longer it has been exposed to the chance of infestations.
