Lead dust is cleaned up by keeping it wet, never sweeping or dry dusting, and capturing it with disposable wet wipes and a HEPA-filtered vacuum. Small amounts of routine household dust can be handled this way. Dust left by sanding, scraping or demolishing old paint is a different job. If you see peeling paint, or dust after renovation work in a pre-1990 home, test first and bring in a licensed abatement crew before you start wiping.
This guide covers what lead dust is, how to clean it step by step, how to handle laundry and waste, and where the line sits between a safe household clean and work that needs a professional.
TL;DR
- Keep everything damp. Dry sweeping, dry dusting and regular household vacuums stir fine lead particles back into the air.
- Use disposable wet cloths, a detergent solution and a HEPA-filtered vacuum. Bag the waste and treat it as hazardous.
- Wash work clothes separately from other laundry, and keep children and pets out of the area until you finish.
- Do not sand, scrape or burn old paint. If dust came from that kind of work, or paint is deteriorating, test and call a licensed abatement contractor.
- We offer lab testing and licensed lead abatement in Ottawa, with itemized quotes.

What lead dust is and why it matters
Lead dust is fine particles that come off lead-based paint, glazing, old plumbing solder or contaminated soil tracked indoors. In older Ottawa homes, the usual cause is paint that has worn on windows, doors and trim, or paint disturbed during a renovation.
The danger is mostly for children. According to Health Canada, household dust is one of the main sources of lead for children under six, who can swallow it by putting hands and objects in their mouths. The same page notes that lead can harm the brain, nervous system, blood system and kidneys, and that even low-level exposure can affect a child’s development.
That is why dust cleanup is not ordinary housekeeping. The particles are very small, they cling to surfaces, and a dry cloth or a standard vacuum can lift them into the air and spread them to rooms that were clean.
If you are not sure whether your home has lead paint at all, start with our guide on why Ottawa homes need testing despite Canada’s 90 mg/kg rule. A house built before the 1990s can have lead under newer layers of paint, even when the surface looks fine.
When a household clean is enough, and when it is not
Two situations look similar but are not the same.
Routine dust control. You have an older home, the paint is intact, and you want to keep dust down. Regular wet cleaning is the right approach. Health Canada says dusting, vacuuming and wet-mopping help keep household dust down, which is an important way to reduce children’s exposure.
Dust from disturbed paint. Someone sanded, scraped, heat-gunned or demolished a wall, or paint is flaking in quantity. This is where cleanup gets harder. Health Canada advises that if you have lead-based paint, you should consider hiring a professional for removal and avoid sanding, scraping or burning it, because those activities release harmful dust.
A B.C. Ministry of Health evidence review adds useful context: dust control tends to work best in homes in poor condition with heavily contaminated dust, and results are inconsistent elsewhere. It also says abatement is recommended for children with higher blood-lead levels. In plain terms, cleaning reduces day-to-day exposure, but it does not remove the source.
Signs you should stop and test
- Paint is chipping, peeling or chalking on windows, doors, baseboards or porches.
- A renovation, even a small one, has already created dust in a house built before 1990.
- You found dust or chips in a room where children play or sleep.
- You bought an older home and plan to open walls, remove trim or strip paint.
Testing is straightforward. HealthLink BC notes that you can use a home test kit or send paint chips to a certified laboratory, and that licensed contractors with X-ray equipment can identify leaded surfaces. We arrange lab analysis for Ottawa homeowners, and our published range for testing and lab analysis is $300 to $600 CAD. If you are weighing whether to test yourself or have someone confirm the result after cleanup, read our guide on DIY or hired lead dust clearance testing.
How to clean lead dust: step by step
This method is for light, household-level dust. It follows the principles in the guidance from Health Canada, HealthLink BC and the Canadian Conservation Institute. If the dust came from demolition or paint removal, skip to the section on professional cleanup.
1. Prepare the space
Keep children, pregnant women and pets out of the area. The Canadian Conservation Institute says children should never be allowed into areas where lead-based materials are being worked on. Close the door to the room and lay plastic sheeting across the doorway if you can.
Turn off forced-air heating and air conditioning, and seal the vents in the room. HealthLink BC advises this during renovation or cleanup work so the system does not carry dust through the house.
2. Put on protective gear
The Canadian Conservation Institute recommends protective clothing for lead work, including coveralls, shoe coverings and gloves, so that contamination does not reach your own clothes or other parts of your home. Disposable items that have been contaminated should be treated as hazardous waste. A fitted respirator with P100 filters is the standard choice for fine dust; check the fit before you begin, and do not rely on a paper dust mask.
3. Mist, then wipe
Lightly wet surfaces before you touch them so the dust stays down. HealthLink BC recommends wetting surfaces and wet-wiping during cleanup. Use disposable paper towels or cloths you plan to throw away, not a sponge you will reuse.
Work from the top of the room down: window sills and wells first, then shelves and trim, then floors. Wipe in one direction, fold the cloth to a clean face, and swap it often. Do not shake cloths out.
4. Use a detergent solution
The Canadian Conservation Institute advises wet cleaning with phosphate-rich detergents such as trisodium phosphate (TSP), along with HEPA-filtered vacuums. If you are using a strong cleaner like TSP, wear gloves and eye protection and follow the label. Many homeowners use a standard all-purpose cleaner and rinse with clean water; either way, the wet method matters more than the brand.
On the question many people search: ordinary dish soap is a detergent, and it can help lift dust when used as part of wet cleaning. What does the work is the wiping, the rinsing and the disposal of the cloths, not a special property of any one soap. Rinse each surface with clean water on fresh cloths so you do not leave a film of contaminated suds behind.
5. Vacuum with a HEPA filter only
After the surfaces dry, go over floors, carpet edges and upholstery with a HEPA-filtered vacuum. A regular vacuum can blow fine lead particles back out of its exhaust. HealthLink BC lists a HEPA vacuum as part of reducing the spread of dust. Vacuum slowly, and overlap your passes.
6. Wet-mop floors twice
Mop hard floors with a detergent solution, then rinse with a second mop head and clean water. Change the water as soon as it looks cloudy. Let the floor air dry.
7. Bag the waste and clean your tools
Put used cloths, mop heads, wipes, vacuum bags and disposable gear into a heavy plastic bag, seal it, and place it in a second bag. Wipe down buckets and tools with wet towels, and bag those towels too.
8. Check the furnace filter
Health Canada says that after dusty projects you should consider changing the furnace filter. If the system was running during the work, replace it before you turn the system back on.
Laundry and personal cleanup
Lead dust travels on clothes, hair and shoes. The rules are simple:
- Take off protective clothing and footwear before you leave the work area, as HealthLink BC recommends.
- Wash work clothes separately from the rest of the household laundry, or discard them when you are done.
- Shower and wash your hair after the job, and wash your hands before eating or drinking.
- Leave work shoes at the door or in a bag.
One load of work clothes does not need special detergent. It needs to be separate, so that dust does not move into your family’s regular wash. Clean the washer with a wet wipe afterwards.
Disposing of lead dust and cleanup waste
Do not put lead-contaminated waste in the regular garbage by default. The Canadian Conservation Institute says to contain, collect and label lead-contaminated waste and dispose of it as hazardous waste, and to contact your municipality, waste management agency or provincial environment ministry for disposal instructions. In Ottawa, call 311 or check the City’s household hazardous waste information before you drop anything off.
The principle comes up in other provinces too. British Columbia’s guideline for lead-containing construction and demolition waste says paint waste, including chips and residues, is expected to fail the leachate test and should be managed as hazardous waste. Rules differ by province, so use the B.C. document as a reference point and confirm Ontario requirements with the City or the Ministry of the Environment.
Leftover paint is a separate matter. Ontario’s government has said unused products like old paint should not go in regular garbage or down the drain; they belong at community environment days or municipal hazardous waste depots.
If a renovation produces a lot of debris, such as plaster, trim or flooring that may be coated in lead paint, we handle debris hauling and post-job documentation as part of the project, so the waste path is recorded.
What lead abatement is
Lead abatement is the permanent work of removing or controlling lead hazards in a building, carried out by trained and licensed crews using containment, dust control and controlled waste handling. It differs from cleaning because it deals with the source: the painted component, the dust-generating surface or the contaminated material.
Abatement can include removing painted components, stripping paint inside a contained area, replacing items like old windows or trim, or sealing surfaces so that lead cannot become dust. The right method depends on the condition of the paint and what you plan to do with the room. We explain the trade-offs in lead abatement versus renovation and in our guide to safe lead paint encapsulation.
How the process works
Exact steps vary by site, but a professional lead removal project in an Ottawa home generally follows this order:
- Assessment and testing. Paint or dust samples go to a lab so the work is based on results, not guesses.
- Scope and quote. The contractor sets out what will be removed or treated, how, and the cost, ideally line by line.
- Containment. Plastic barriers, sealed vents and controlled entry points keep dust inside the work area. The heating and cooling system is isolated.
- Removal or treatment. Crews use wet methods and low-dust tools, not dry sanding or open-flame burning.
- Cleanup. Surfaces are wet-cleaned and HEPA-vacuumed, and waste is bagged and labelled.
- Clearance. Dust wipe testing confirms the area is clean before it is reoccupied.
- Documentation. You receive records of the work and waste handling.
Ontario’s rules for construction projects sort lead work into classes by the risk the task creates. The province’s classification of work shows that some operations, such as dry removal of lead-containing mortar, require stricter controls than others. That is the reason a contractor should be able to tell you which class your job falls into and what controls come with it.
What professional cleanup looks like, and what it costs
The amount of dust determines the price. A single window sill and a gutted basement are not comparable jobs. Our published ranges for Ottawa-area work are:
| Service | Published range (CAD) |
|---|---|
| Testing and lab analysis | $300 to $600 |
| Small Type 1 or 2 abatement jobs | $1,500 to $3,500 |
| Vermiculite attic removal | $5,000 to $15,000 |
| Whole-home or Type 3 work | No published price; quoted after assessment |
These are ranges, not quotes. Final cost depends on the size of the area, the materials, access and the test results, which is why we provide free estimates and itemized, line-by-line quotes. Each line tells you what you are paying for, so you can compare it with another bid on equal terms.
If lead removal is part of a larger renovation, how you structure the contract affects timing and coordination. A short read on design-build versus design-bid helps you decide whether one team should manage abatement and rebuilding or whether you want separate bids.
Special cases that need extra care
Exterior paint and soil
Lead from exterior paint ends up in soil near the foundation, and children track it indoors. Exterior work has its own methods for containing debris and protecting landscaping. See our homeowner’s guide to exterior lead paint removal in Ottawa.
Window glazing and original windows
Old windows are a common source of lead dust because opening and closing them grinds painted surfaces together. Before you replace them, see our note on lead in window glazing to weigh restoration against replacement.
Other hazards in the same walls
Older homes often combine lead paint with asbestos, vermiculite insulation or mould. Opening a wall to deal with one can expose you to another. Our overview of hidden renovation hazards in older Canadian homes covers what to check before demolition starts.
Our perspective
Most of the lead dust problems we see in Ottawa did not start with old paint. They started with a well-meant weekend of sanding, scraping or tearing out trim. The paint was stable until somebody disturbed it, and then the dust went into the carpets, the ducts and the kids’ bedrooms.
Our advice is to treat cleanup and abatement as two separate jobs. Wet cleaning keeps routine dust down, and it is worth doing every week in an older house. Once paint has been disturbed, though, the right move is to stop, test and have the area contained and cleared by a licensed crew.
We prefer to put a number on a problem before anyone touches it. That is why we send samples to a lab, write up the scope in an itemized quote, and confirm with clearance testing at the end. Because we also handle demolition, renovation and debris hauling, there is one team accountable from containment to the new finish, and no gap where dust can slip through between trades.

FAQ
Does dish soap remove lead dust?
Dish soap can lift dust as part of wet cleaning, but it is the method that matters. Wipe with disposable cloths, rinse with clean water on fresh cloths, and finish with a HEPA vacuum. Detergents with phosphates, such as TSP, are also recommended by the Canadian Conservation Institute for wet cleaning.
How do I wash clothes with lead dust on them?
Wash them separately from the rest of your laundry, or throw them out if they are heavily contaminated. HealthLink BC advises removing protective clothing before leaving the work area. Wipe out the washer afterwards with a wet cloth and bag the cloth.
Can I use a regular vacuum on lead dust?
No. A standard vacuum can pass fine particles through its exhaust and spread them around the room. Use a HEPA-filtered vacuum after wet wiping, and bag the contents as hazardous waste.
How bad is lead dust?
It is most harmful to young children, who can swallow it through hand-to-mouth contact. Health Canada says lead can affect the brain, nervous system, blood and kidneys, and even low exposure can affect a child’s development. If you think a child has been exposed, talk to your family doctor or public health unit about blood testing.
When should I call a professional instead of cleaning it myself?
Call a professional when paint is flaking, when dust came from sanding, scraping or demolition, or when you plan to open walls in a pre-1990 home. Test first, then have a licensed crew contain and clear the area. Testing confirms the scope before you spend money on the work.
