Purchasing a Century Home requires doing your homework. When buying an older home you are usually buying a home with built in character which has withstood the test of time and is hopefully still in living condition. There are some common issues that you might discover when purchasing an older home. Having your home inspected by someone with years of experience is paramount to ensure you invest your money wisely. I have listed some of basic problems encountered over the years..
Your century homes foundation is probably constructed of cement and rock. Older homes do not have exterior waterproofing and there will be no weeping tile draining into sump. This inspection area is one of the most important and expensive to repair if faulty. Many century homes will have little trenches in concrete around perimeter that drain into a dug drain hole.
Knob and tube wiring was typically installed in older homes when electricity became available. You have to have a home inspector or electrician check to ensure all the knob and tube wiring was replaced, many times I have found live Knob and Tube in service chases or in attics. Even if knob and tube was upgraded, the installed cable may not have a ground wire attached. Some homes have upgraded outlets but no ground is not available.
Asbestos was installed in most older homes as it was the insulation of choice back in the day. Many older homes had hot water boilers with cast iron radiators. This systems were typically insulated with asbestos insulation. Many times during an inspection I find the basement asbestos has been removed but the heat ducts passing through the home still have asbestos insulation attached. Asbestos requires professional removal which is very expensive.
Lead plumbing pipes and galvanized plumbing lines can be very expensive to replace and were used on most older homes. Most insurance companies in Ontario will not insure a home with galvanized plumbing pipes. Galvanized pipes are past their life expectancy and there is the possibility of water contamination from corroding pipes.
Older homes may have many layers of lead paint which has built up over the years. Lead-based paint is a major source of lead poisoning for children and can also affect adults. In children, lead poisoning can cause irreversible brain damage and can impair mental functioning. It can retard mental and physical development and reduce attention span. It can also retard fetal development even at extremely low levels of lead. Thus, young children, fetuses, infants, and adults with high blood pressure are the most vulnerable to the effects of lead.
Your house is old and gorgeous but how is it heated. During inspections I have had clients who were quite surprised to learn that the only heat on second floor were some grilles in the floor. So much for privacy or toasty warm beds. Also older homes sometimes buried their oil tanks which is no longer permitted. Removing a buried oil tank can easily cost upwards of $20,000.00 and if it has leaked, the sky’s the limit on costs.
