If your house was built before 1960, the paint on its doors probably contains lead. Doors are one of the riskiest places for it, because every swing and every latch rubs the paint and wears it into chips and fine dust. The safest first move is usually to leave intact paint alone, keep children away from worn edges, and have the paint tested before anyone sands, scrapes or heats it. Stripping is a job for a certified crew when the paint is failing, when you are renovating, or when the door is in a home with young children or a pregnancy.
This guide explains how to tell whether a door has lead paint, when it is a real hazard, what “stripping” involves in Ontario terms, what your options are, and what a professional job costs in Ottawa.
TL;DR
- Homes built before 1960 are likely to contain lead-based paint, and homes built from 1960 to 1990 may have it on exterior surfaces, including front and back doors.
- Doors are a friction surface, so normal use can create lead dust. Chipping, flaking paint within a child’s reach is the clearest reason to act.
- Intact lead paint is sometimes safer left undisturbed or sealed in than stripped. Never dry sand, scrape or burn it.
- Test first. A lab analysis in Ottawa typically runs $300 to $600 with HMJ Contracting, and a small certified abatement job runs $1,500 to $3,500.
- Stripping is classed by risk (Type 1, 2 or 3 in Ontario), and the class decides the precautions required.

Why doors are a special problem
Health Canada points out that lead-based paint is a serious hazard when it is chipping, flaking, or within reach of children who may chew on it. It also notes that friction from normal wear, as on doors and windows, can expose people to lead. You can read the details on the Health Canada lead-based paint page.
Think about what happens at a door:
- The edge rubs the frame every time it closes, grinding the paint to powder.
- The knob, latch and hinge areas are touched constantly, so dust gets onto hands.
- The bottom of the door and the threshold collect dust and are at a toddler’s eye level.
- Old doors have often been repainted a dozen times, so the lead layer sits under newer coats that crack along with it.
That last point matters. A door can look fine on the surface and still produce lead dust at the edges, because the failure begins in the old layers underneath.
How to tell if your door has lead paint
Start with the age of the house. According to Health Canada, homes built before 1960 are likely to contain lead-based paint, and homes built between 1960 and 1990 may have it on exterior surfaces. Health Canada’s lead information package adds that Canadian paint makers were asked to stop using lead compounds in consumer paints voluntarily by the end of 1990, and that indoor consumer paint after 1992 was virtually lead-free. You can see that on the Health Canada lead information page.
So a practical rule for Ottawa homes:
| Home built | Chance of lead paint on doors | What to do |
|---|---|---|
| Before 1960 | Likely, inside and out | Assume it is present until tested |
| 1960 to 1990 | Possible, especially exterior doors and frames | Test before any sanding or stripping |
| After 1992 | Very unlikely for indoor consumer paint | Standard renovation care |
Age is only a hint. To know for sure, Health Canada says you can send paint-chip samples to a lab or hire a contractor with proper X-ray equipment that detects lead on painted surfaces. Store-bought swab kits are tempting, but a lab result is the one you can act on and show a buyer or a contractor later.
If you want the Ottawa-specific picture, our article on why Ottawa homes still need lead testing covers it, and our guide to the 90 mg/kg rule explains the federal limit for lead in paint.
How to take a sample without making things worse
Sampling is itself a disturbance, so keep it small and tidy. Mist the spot lightly, cut a small piece through all the layers with a clean blade onto a sheet of plastic, seal it in a bag, and wipe the area afterwards. Ask the lab how big a sample it wants. If the door is in poor condition, or a child lives in the house, have a professional take the sample instead.
Is it safe to leave lead paint on a door?
Often, yes, for a while. Health Canada states that leaving lead-based paint undisturbed is sometimes safer than removing it, and that covering the area with wallpaper, wallboard or paneling adds a further layer of security. A solid, well-bonded coat that nobody is rubbing is not producing much dust.
A door is the exception to “leave it alone” more often than a wall, because it moves. Use this as a quick guide:
- Intact paint, rarely used door (a closet or a bedroom door with a smooth edge): leave it, keep it clean, and watch it.
- Intact paint, heavily used door (the front door, a sticking door, a door that rubs its frame): the friction will wear it down. Plan to seal it properly or replace it.
- Chipping, flaking or powdery paint: stop using the surface as is, keep children and pets away, and arrange removal or containment.
- Any door you are about to sand, plane, rehang or cut: test first.
What about painting over it?
The forum advice that tops many searches is to prime over it with a lead-lock primer and move on. A fresh coat can help seal sound paint, but it does not solve a door that keeps rubbing, and paint applied over flaking layers will fail along with them. Encapsulation works when the surface is sound and the product is chosen for the job. Our homeowner’s guide to safe lead paint encapsulation walks through when it holds up and when it does not. For a door with failing paint, containment is a stopgap, not a fix.
Can you strip lead paint from a door yourself?
Legally, a homeowner working on their own house is not in the same position as an employer. Ontario’s Occupational Health and Safety Act requires employers to protect workers, and Ontario’s lead regulation requires lead assessment and control programs, but it does not apply to construction projects. The province’s legal requirements page for lead on construction projects sets this out. Instead, construction work is covered by a guideline.
That guideline sorts lead work by risk. The Ontario Ministry of Labour says measures and procedures depend on whether the operation is Type 1, 2 or 3, as described in section 6 of its lead guideline. In plain terms, the more dust or fume a method creates, the stricter the controls: containment, protective gear, air management and clean-up.
Here is how that thinking applies to a door:
| Method | Dust or fume risk | Our view |
|---|---|---|
| Dry sanding or power sanding | Very high | Do not do this |
| Dry scraping | High | Avoid |
| Heat gun or torch | Lead fume and fine particles | Avoid |
| Chemical stripper, applied wet | Lower dust, but messy waste | Only for small, sound pieces, with proper gear and containment |
| Removing the door and replacing it | Low if the door is taken out intact and bagged | Often the cleanest choice |
| Professional abatement on site or off site | Controlled | Best for failing paint, multiple doors, or children in the home |
Health Canada’s guidance supports the first point: if lead paint is a hazard, remove it following specific guidelines, and consider hiring an expert. A reader of the top-ranking pages will see that liquid removers are mentioned for small areas such as doors and woodwork, with manufacturer’s instructions to follow. That is the lowest-risk DIY route, but it still creates lead-contaminated waste and residue, and it needs gear and a plan.
If you do decide to work on it yourself
We would rather you hire a certified crew, but if you are dealing with a single, small, sound piece of trim or a door, the principles are the same ones the pros use:
- Test first and know what you are dealing with.
- Keep people out. No children, pregnant women or pets in the area until the work and clean-up are finished.
- Seal the room. Cover the floor and nearby surfaces with heavy plastic, and close off vents.
- Use wet methods only. Never dry scrape, dry sand or heat the paint.
- Protect yourself. Wear a properly fitted respirator rated for lead dust, disposable coveralls and gloves. A basic paper dust mask is not enough.
- Bag everything as you go, including the plastic sheeting and wipes.
- Clean thoroughly with a HEPA-filter vacuum and wet wiping, and never dry sweep.
- Wash up before eating, and wash your work clothes separately.
A regular household vacuum is not designed to hold fine dust and can blow it back into the room, which is why a HEPA vacuum is the standard for lead clean-up. After the work, a professional can confirm the area is clean.
What happens to the waste
Lead paint chips, residue and contaminated wipes are not ordinary garbage. Rules differ by province. In British Columbia, for example, the government’s guideline says lead paint waste from removal must be contained and recommends managing it as hazardous waste, with licensed transport and authorized facilities for off-site shipments, and an exemption for homeowners taking household hazardous waste to authorized facilities. That is in the B.C. guideline on lead-containing construction waste.
In Ontario, the province tells residents to take unused paint to community environment days or collection depots instead of the regular garbage, as shown in its household hazardous waste announcement. For leftover paint and bagged residue from a door in Ottawa, check the City’s current drop-off rules before you load the car. Our article on renovation waste in Ottawa and why to call 311 first explains how to do that.
When we do the work, debris hauling and post-job documentation are part of the job, so the waste leaves with us and you have a record of it.
What if you think you breathed or swallowed lead dust?
A single brief exposure to a little dust is different from repeated exposure, but you should not guess. If a child has been chewing on a painted door edge, or someone was in the room while old paint was sanded or heated, speak to your family doctor or call Telehealth Ontario at 811 and ask about a blood lead test. Children under six and pregnant women are the groups to raise first. Tell the clinician what happened, when, and where the paint came from. Meanwhile, stop the source, keep everyone out of the area and avoid dry sweeping.
Our point of view: why doors deserve a plan
We have worked in Ottawa homes for more than 25 years, and doors are where we see the most avoidable mistakes. A homeowner buys a 1950s house, loves the original solid-wood doors, and takes a belt sander to the first one on a Saturday. The dust travels through the heat ducts, and the clean-up ends up costing far more than the stripping would have.
Our approach is the opposite. We test first, so you know whether you have a lead problem at all. If you do, we sort the options honestly: leave it, seal it, strip it, or replace the door. Sometimes the right answer is to take the door out intact, bag it, and fit a new one. Sometimes a historic door is worth saving, and we strip it under containment, with air management and wet methods.
What we will not do is hide the cost. You get a detailed, itemized quote with each line explained, usually within 24 hours of the estimate. Because we handle abatement, demolition and renovation under one roof, you do not need to coordinate three contractors when the door is part of a bigger project.
If your door is only part of a wider problem, such as peeling paint across a house, read our guide to lead abatement versus renovation. For exterior doors and frames, see exterior lead paint removal in Ottawa.

What professional help costs in Ottawa
Our published ranges, from our services pages, are a useful starting point. Every home is different, so your own quote will be itemized after an inspection.
| Service | Published range |
|---|---|
| Testing and lab analysis | $300 to $600 |
| Small Type 1 or 2 abatement jobs | $1,500 to $3,500 |
| Single-room strip-out (demolition) | $1,000 to $4,000 |
| Whole-home or Type 3 abatement work | Quoted after inspection |
A single door or a few doors usually falls into the small-job category, particularly when the paint is limited to the door and frame. When doors are part of a bathroom or kitchen renovation, the abatement is best done before the new work starts, so you are not renovating over a hazard.
Work with a certified crew
HMJ Contracting is licensed and insured for abatement work in Ottawa, Renfrew and the surrounding area.

If you have an older home with doors you are not sure about, see our abatement services and request a free estimate.
If the door is one piece of a larger renovation, you can browse everything we do on our services page.
FAQ
Is it okay to paint over lead paint on a door?
Sometimes, if the existing paint is sound and not wearing away. Health Canada says that leaving lead paint undisturbed can be safer than removing it. On a door that rubs, sticks or already flakes, new paint will not hold, so it is better to have it tested and treated properly.
Does dish soap remove lead from a door or floor?
Soap and water on a disposable cloth will lift loose dust from smooth surfaces, but it does not make a contaminated surface safe by itself. Use new cloths, bag them, and then have a professional check the area if sanding or scraping took place. Use a HEPA vacuum rather than a regular one.
How do I know if my door has lead paint?
Check the age of the home first. Houses built before 1960 are likely to have it. Then send a paint-chip sample to a lab or hire a contractor with X-ray equipment, as Health Canada describes. Swab kits can hint at lead but are not a replacement for a lab result.
Do I have to hire a professional to remove it?
You are not required to hire one for your own home in Ontario, but Health Canada advises considering an expert when lead paint is a hazard. We recommend it when paint is chipping, when children live in the home, or when you are renovating. Our team handles removal, hauling and documentation.
Where do I put the paint chips and debris?
Do not put them in regular garbage or recycling. Bag and seal them, and ask the City of Ottawa about the current hazardous-waste drop-off options before you go. Ontario directs residents to depots and community environment days for paint.
