Lead was used in old water piping – primarily on the main service line to the house, in solder used with copper pipe joints and in many older paints. Lead-in-water and lead-based paints have been proven to be hazardous, particularly to younger children. In addition to developmental problems in children, lead poisoning can cause hypertension, nerve disorders, muscle and joint pain, memory/concentration problems, and for women, pregnancy problems.

Considerations
Very old homes may still have lead supply lines, however, the potential concern related to the use of lead based solders may be more prevalent. Lead solders were phased out in the mid-1980’s but there are still many homes – particularly those with high acid levels in the water supply – that may still be at risk of exposure. Allowing water to run for a period of time before drinking it or installing a filtration system may help minimize concerns. The HouseMaster Technical Staff states that lead-based paint hazards are greatest when dust is created by friction surfaces, such as windows, or when major paint deterioration occurs. Pre-1978 homes are more likely to contain lead- based paint as it was phased out after then. Testing is advised whenever there is an increased risk of exposure to lead-based paint hazards. If a serious concern exists, encapsulation or removal are the remedial options.
