Lead Paint in Older Massachusetts Homes: What to Know Before You Repaint

Lead-based paint was banned for residential use in the United States in 1978. Any home built before then may have it somewhere, and the older the house, the higher the odds. Homes built before 1950 are the most likely to have lead paint, often in multiple layers and in higher concentrations.

The places it shows up most often are the surfaces that get the most wear and weather: windows and window sills, doors and door frames, stairs and railings, porches, exterior siding and trim. Friction surfaces like window sashes rubbing in their tracks can grind paint into fine dust even without any renovation.

You cannot tell by looking. A house that was repainted recently can still have lead paint under the newer coats, and that becomes an issue as soon as someone sands or scrapes down to it.

Most painting work involves surface prep: scraping loose paint, sanding glossy or rough areas, and sometimes removing old paint with heat. On a pre-1978 home, those steps can release lead dust and chips that settle on floors, window sills, soil and play areas. The dust is fine enough that you may not see it.

Young children are the most vulnerable because they crawl, put their hands in their mouths and absorb lead more readily as they grow. Pregnant women are also at higher risk. Even low levels of lead exposure in children have been linked to learning and behavior problems, which is why both federal and Massachusetts rules focus heavily on homes where young kids live.

The EPA Renovation, Repair and Painting (RRP) Rule applies to paid work on pre-1978 homes, child care facilities and schools that disturbs painted surfaces above certain minimum amounts. As a general summary, those thresholds are more than six square feet per room on the interior or more than twenty square feet on the exterior, and window replacement is covered regardless of size.

Under the rule, the firm doing the work must be certified, at least one certified renovator must be assigned to the job, and crews must follow lead-safe work practices: containing the work area, avoiding banned methods such as open-flame burning and high-speed power sanding or blasting without proper controls, and cleaning and verifying the area at the end. Contractors are also required to give the occupants the EPA pamphlet called Renovate Right before work begins.

In Massachusetts, the RRP program is run at the state level by the Department of Labor Standards, which licenses and oversees firms and renovators. That is where you can check whether a contractor is properly certified.

Massachusetts has its own Lead Law, which is separate from and in some ways stricter than the federal rules. In general terms, it requires owners of homes built before 1978 to address lead hazards when a child under six lives in the home. That usually means deleading or bringing lead hazards under control through a process overseen by licensed professionals and inspectors.

Deleading is not the same as painting. It is specialized work done by licensed deleaders, with inspections before and after. A regular painting project, even one done with lead-safe practices, does not by itself make a home compliant with the Lead Law. If you are a landlord, are buying or selling an older home, or have a young child in a pre-1978 house, the Massachusetts Childhood Lead Poisoning Prevention Program, part of the Department of Public Health, has detailed guidance and lists of licensed inspectors.

If your home was built before 1978 and you are planning work that will disturb paint, it makes sense to find out what you are dealing with. Options range from EPA-recognized test kits for specific surfaces, to testing by a certified renovator, to a full inspection by a licensed lead inspector, which is what Massachusetts requires for Lead Law compliance.

Testing changes how a project is planned. If the surfaces test negative, standard prep methods may apply. If they test positive, or if testing is skipped, the work should be treated as lead paint and done with lead-safe practices. As a rough guide, lead-safe prep adds time and cost compared with standard prep because of containment, special cleanup and disposal. Ask for that cost to be shown clearly in your written estimate.

Ask whether the firm holds a Massachusetts Lead-Safe Renovation Contractor license, the state's version of EPA RRP certification, and confirm it with the Department of Labor Standards before you sign. Ask how the crew will contain the work area indoors and outdoors, how they will protect soil, gardens and play areas from chips, which removal methods they use and which they avoid, and how they clean up and verify the area at the end of the job.

Do not assume every painter is certified. Some do not take on pre-1978 work that triggers the rule, and a responsible contractor will tell you clearly whether they can do your project in compliance. Blessed Partners & Paint Group recommends that every homeowner with an older house confirm the certification of whoever they hire, and you are welcome to raise these questions during a free estimate.

Keep children and pets away from the work area until cleanup is complete. Move toys, outdoor furniture and garden items away from the house before exterior prep. Ask the crew to close windows near the work area and to tell you when areas are safe to use again.

After the project, wet-wipe window sills and floors regularly and keep painted surfaces in good condition. Intact, well-maintained paint is the best long-term defense against lead dust in an older home.
