Can I paint over lead paint safely or does it need to be removed first in my NB home?

In most cases, encapsulation — painting over intact lead paint with a fresh coat — is actually the recommended approach, and is safer than removal. But if the lead paint is peeling, flaking, or on a surface subject to friction (doors, windows, trim), removal or professional encapsulation is necessary, and that work should always be done by a professional with lead-safe practices. This distinction matters enormously for the safety of you and your family.

New Brunswick has a large stock of pre-1978 housing, particularly in the older neighbourhoods of Saint John, Moncton, and Fredericton. Lead was a common additive in residential paint until Canada phased it out in the late 1970s. If your home was built before 1978, assume there is lead paint somewhere — most commonly on window frames, door frames, trim, baseboards, exterior siding, and older kitchen and bathroom surfaces. Health Canada estimates that the older the home, the higher the lead concentration in early paint layers.

The key principle is this: lead paint that is in good condition, firmly adhered, and not subject to friction or abrasion poses minimal immediate risk as long as it stays intact. Painting over it with a fresh coat of paint — what professionals call encapsulation — seals the lead beneath a new barrier and is Health Canada's preferred approach for stable lead paint. The danger comes when lead paint is disturbed: sanding, scraping, heat-gun stripping, or cutting through it generates lead dust and paint chips, which are the actual hazard, particularly for children under 6 and pregnant women.

Before you do anything with suspected lead paint in your NB home, do a lead test. Lead test swabs (available at hardware stores across NB for about 0-15 each) give a result in minutes. A lab-based dust wipe test is more accurate for confirming whether a room has been contaminated. If the test is positive and the paint is intact, you can safely paint over it with proper precautions: wipe the surface with a damp cloth to remove dust, apply a bonding primer, then your finish coat. Do not sand or dry-scrape the surface.

If the lead paint is peeling, chipping, or on a friction surface (window sashes, door edges), removal is necessary — and this is unequivocally a job for a professional with lead-safe work practices. The work area must be sealed with plastic sheeting, occupants (especially children and pregnant women) must vacate the home during and after work until cleanup is confirmed complete, workers must wear full-face respirators with P100 cartridges and disposable coveralls, and lead-contaminated debris must be disposed of as hazardous waste. This is not a DIY project. Not because of bureaucratic rules, but because lead dust at this level is genuinely dangerous to your family's health.
