Lead Paint in Pre-1960 Kitchener Homes: What Changes When You Repaint
If your Kitchener house was built before 1960, there is a good chance at least one of the layers under the current paint contains lead. Painting over it is not the risk. Sanding, scraping and heating it is.

A large share of Kitchener's older housing stock predates 1960: the brick and frame houses downtown, in Cedar Hill, around Victoria Park and in the Civic District, and the older farmhouses on the city's edges out toward Breslau. Those houses have been repainted many times, and the paint on the trim, the window sashes and the exterior siding often includes layers from before lead was removed from household paint. As long as that paint stays intact under newer coats, it is not a hazard. It becomes one when prep work turns it into dust and chips.
Which houses are likely to have lead paint
Health Canada's guidance is direct: a home built before 1960 probably contains lead-based paint. For homes built between 1960 and 1990, the exterior may contain it. Homes built after 1990 should not.
In practice, lead paint in a Kitchener house is most often found on:
- Window sashes, sills and frames, where friction and weather wear the paint.
- Interior trim, baseboards, doors and door frames.
- Exterior wood siding, porches, railings and soffits.
- Stairs and railings.
- Plaster walls in rooms that were painted with oil enamels, such as kitchens and bathrooms.
Health Canada notes that the risk is greatest for children, who absorb lead easily, and that unborn children are at risk too. Even small amounts of lead dust are dangerous to infants and young children.
How to find out for sure
You cannot tell by looking. Health Canada suggests sending paint chip samples to a lab for analysis, or hiring a contractor with the proper X-ray equipment to test surfaces in place. A lab test on chips from the surfaces you plan to disturb, taken down through every layer to the bare wood or plaster, is the most useful information to have before a quote is written. If testing is not done, the sensible approach on a pre-1960 house is to assume lead is present on older painted surfaces and plan the prep accordingly.
What not to do
Health Canada's advice is not to use sanders, heat guns or blowlamps to remove lead-based paint, because they create toxic dust and fumes. That rules out the fastest ways of stripping old trim or exterior siding.
Ontario's guideline on lead on construction projects, which applies to workers, ranks removal methods by how much exposure they create:
- Lower-risk (Type 1): removing lead coatings with a chemical gel or paste and a fibrous laminated cloth wrap; using a power tool that has an effective dust collection system with a HEPA filter; and using non-powered hand tools other than for manual scraping or sanding.
- Moderate (Type 2a): scraping or sanding with non-powered hand tools.
- High (Type 3a): using power tools without effective HEPA dust collection, and burning a surface that contains lead.
- Highest (Type 3b): abrasive blasting.
That ranking is a good guide for homeowners too. An ordinary orbital sander on old window trim is at the high end. A chemical stripper paste, or a sander with a HEPA vacuum attached, is at the low end.
How a lead-aware repaint is done
- Stabilize, do not strip, where possible. Paint that is sound only needs cleaning, a light scuff with dust control and a good primer. Most of the lead stays sealed under the new coat.
- Contain the work area. Floors and furniture are covered with plastic sheeting taped at the edges, doorways are closed off, and heating and cooling vents in the room are covered.
- Remove loose paint with low-dust methods. Wet scraping, chemical paste strippers or HEPA-extracted sanding, not dry power sanding or heat.
- Keep people out. Health Canada advises keeping children and pregnant women away from the work area.
- Clean up properly. Chips and scrapings go into a sealed container marked as hazardous waste, and surfaces are wiped with damp cloths that are then thrown away. A HEPA vacuum is used rather than a household vacuum or a broom.
Old oil-based trim needs the right primer before latex topcoat goes on, which is a separate issue from lead but usually part of the same job.
Interior or exterior first?
On most pre-1960 houses the worst lead-paint condition is outside, where paint on siding and trim has peeled and chalked. Loose exterior paint also ends up in the soil next to the house, where children play. If both need doing, the exterior often has the stronger case. See exterior painting of siding and trim and interior house painting.
What to ask for in the quote
- Which surfaces will be scraped or sanded, and how.
- How the work area will be contained and cleaned each day.
- Whether any surfaces will be replaced or stripped rather than painted over.
- How paint waste will be bagged and disposed of.
The painter writes the prep into the quote line by line, which is where lead-safe methods show up. Heavy prep on old surfaces is priced differently from a repaint on sound drywall; the Kitchener painting cost guide explains how. To have the surfaces looked at, book a visit.
