Older home — the hidden lead and asbestos risks

What to do right now

If you think your older home may have lead paint or asbestos, the safest first step is simple: do not disturb it. Do not sand, scrape, drill, cut, break, or tear out the material to “see what’s underneath.” Keep children, pregnant people, and pets away from the area until you know what it is.

If work has already started, stop the work if you can do so safely. Close off the area as much as possible, avoid tracking dust through the home, and do not dry sweep debris. Then arrange testing by a certified professional before anything else happens.

1. Stop renovation, repair, or demolition work.
2. Keep people and pets out of the area.
3. Do not touch, sweep, sand, or vacuum suspected material with a regular household vacuum.
4. Get the material tested by a certified professional first.
5. For a health concern, especially possible lead exposure in a child, contact a doctor or your local health department.

Why older homes can have hidden hazards

Homes built before 1978 often contain lead-based paint somewhere in the property. It may be on walls, windows, trim, doors, porches, stairs, railings, or older painted siding. Even if the paint has been covered with newer paint, it can still become a problem if it is chipped, peeling, or disturbed during repair or renovation.

Asbestos was widely used in many building products, especially in homes built before the 1980s. It may be found in pipe insulation, old floor tile and mastic, popcorn ceilings, textured coatings, cement siding, roofing materials, vermiculite attic insulation, and some wall or furnace materials. You usually cannot tell by looking whether a material contains asbestos.

A material that is in good condition and left alone may not create an immediate risk. The danger usually rises when lead dust or asbestos fibers are released into the air or spread through the home during sanding, scraping, demolition, or improper cleanup. That is why testing first matters so much in older homes and before any renovation or sale.

Health risks without the scare tactics

Lead is most dangerous as dust or chips that can be swallowed or breathed in. Young children are at special risk because they may touch dusty surfaces and put hands or toys in their mouths. Lead exposure can harm a child’s developing brain and nervous system. Adults can also be affected, and pregnant people need to be especially careful.

Asbestos is most dangerous when tiny fibers become airborne and are breathed in. Long-term or heavy exposure can increase the risk of serious lung disease. The risk is generally tied to exposure over time, but the right response is still to avoid disturbing suspected material and have it evaluated properly.

This page is general educational information, not medical advice. If you are worried that someone in the home may already have been exposed, contact a doctor or your local health department. For more background, you can also explore our hazards hub.

• Lead risk often comes from dust created during repair or paint disturbance.
• Asbestos risk often comes from fibers released when old materials are cut, broken, or removed.
• Children, pregnant people, and anyone with breathing concerns should be kept away from suspected areas.

How testing works

The right test depends on the material. For lead paint, a trained professional may use approved methods to check painted surfaces and, when needed, collect samples for analysis. For asbestos, testing usually means a trained inspector carefully takes samples of suspected material and sends them to an accredited laboratory. Because sampling itself can disturb the material, it should be done by someone qualified to do it safely.

If you are planning renovation in a pre-1978 home, ask specifically about lead-safe evaluation and whether the company follows EPA Renovation, Repair and Painting requirements when paint may be disturbed. For asbestos, ask whether the inspector or contractor holds the state-required asbestos license for inspection or abatement in your area.

Do not rely on guesswork, a hardware-store opinion, or a photo alone. And do not break off a piece yourself unless a local authority specifically tells you to and you understand the risk. If you want more detail on asbestos testing, see how to test for asbestos.

• Ask what material will be sampled and how the area will be protected.
• Ask which accredited laboratory will analyze the sample.
• Ask when results are expected and whether a written report is included.
• Keep a copy of the report for future repairs, renovation, or sale.

What the law usually requires

Lead and asbestos work is heavily regulated, and the exact rules vary by state and local area. In plain language, if renovation work will disturb painted surfaces in a pre-1978 home, EPA Lead RRP rules often require the firm to be certified and to use lead-safe work practices. That includes controlling dust, protecting the area, and cleaning properly.

For asbestos, removal and other abatement work is typically controlled by state licensing rules. Many states require asbestos inspectors, contractors, and workers to hold specific licenses or certifications. Proper containment, safe handling, and lawful disposal are a major part of the job. In some places, even sampling has rules.

Do not take a contractor’s word for it. Verify the company’s certification, license status, and insurance yourself with your state authority and, where relevant, EPA records. Get the scope of work and cleanup steps in writing before you agree to anything. This is general information, not legal or regulatory advice, and local requirements can be stricter than the basic rule.

Red flags to watch for:
- No license or certification information
- "We’ll just scrape or sand it off"
- No containment plan
- Cash-only or pressure to sign immediately
- No written scope, cleanup plan, or disposal details

Honest cost ranges and how to find the right pro

Costs vary a lot based on what the material is, how much there is, where it is located, how easy it is to access, your local labor market, and what testing, containment, and disposal are required. These ranges are not quotes, but they can help you plan.

Testing is often the first cost. Small lead paint or asbestos sampling jobs may run from roughly $250 to $800+, while larger inspections or multiple samples can cost more. If abatement is needed, lead-safe repair or paint stabilization may be a smaller job, but larger lead abatement projects can run from the low thousands into much more. Asbestos removal can range from around $1,500 to several thousand dollars or higher depending on the material, location, and containment needs. Disposal rules can add cost.

The safest approach is to get more than one written estimate when possible and compare scope, not just price. A low price is not a bargain if the company skips containment, cleanup, or legal disposal. See more general pricing guidance at costs.
