WHEN WAS LEAD PAINT USED?
Up until the late 1970′s lead was widely used as a paint additive to yield specific colors and increase the overall quality of the paint. In the US, the use of significant amounts of lead as an additive in paint was banned from residential use by the CPSC in 1977. Keep in mind that old stock often continued to be used in the few years to follow.
SAFETY & COST CONCERNS
Inhaling or ingesting even small amounts of lead or lead containing materials poses a serious health risk, especially to children and pregnant women. Children can be inclined to eat paint chips because they actually taste sweet. I encourage doing further research to know what precautions are necessary. However, it’s also important to know that, when solidly encapsulated, the possibility of exposure (beyond normally occurring trace amounts) can be substantially reduced. It’s often safer to paint over lead paint than to attempt to remove it entirely.
Recent regulations in King County require contractors to meet more stringent requirements on job sites where lead paint is present or may be present. Surfaces that contain lead paint cannot be sanded or otherwise improperly handled. These regulations help further protect against exposure to lead. If you plan on remodeling, it’s worth noting that these requirements can have a marginal increase the cost.
Testing for lead requires specialized equipment or invasive sampling and is not offered as part of a standard home inspection. If you are interested in having a home tested there are a few main options:
Do-it-yourself lead test kits can do a good job at detecting lead in isolated surfaces if the instructions are closely followed. At $5 to $10 per swab and the availability of multiple swab packs, the kits are much less expensive than the alternative of having an on-site professional lead inspection. One significant down side to these kits is that they require exposing and testing a section of of each individual paint layer. This can require practice and patience. These kits are also not recognized as an official evaluation by agencies like the EPA and HUD.
Paint chip sample testing is an effective method of testing a given sample at a laboratory (see the “Service Providers” section below). This method does involve removing small samples of paint, usually from multiple locations throughout the home.
Professional on-site testing is a much more thorough examination of the home. This non-invasive testing uses a specialized XRF (X-ray fluorescence) scanner that does not require any damage to the wall surfaces. On-site lead inspections generally costs around $300 to $400 (see “Service Providers” section below).
