Do I need to test for lead paint before sanding walls in an older home?

Yes. If your home was built before 1978, test the paint first or treat it as lead paint until a test says otherwise, and don't dry-sand it in the meantime. Sanding turns old paint into fine dust, and that dust is how lead spreads through a house.
The nuance is that the paint on your walls may be fine, but you can't tell by looking. A home can have lead under newer coats, and a repaint doesn't remove what's underneath. The age of the house is the deciding factor, and a test turns a guess into an answer.
Why sanding is the step that matters
Lead paint that is intact and undisturbed is generally a smaller concern. The problem starts when it is sanded, scraped or torn, because that releases dust you can't see. The dust settles on floors, window sills and furniture, and it is hard to clean up fully.
Interior painting almost always involves some sanding. Patched holes get smoothed, glossy surfaces get scuffed so new paint grips, and rough spots get knocked down. In a pre-1978 home, each of those steps is a chance to disturb old paint, so the prep needs a plan before it starts.
The details depend on the job and the place. Check with the EPA, your state agency or the local building department about what applies to your project.
What you can check yourself
Confirm when the house was built
County property records or your closing paperwork usually show the year. If it's before 1978, plan on testing before any sanding.
Look at the paint's condition
Look for peeling, chipping or a cracked, alligatored texture, especially on trim, doors and windows. Don't scrape at it. Just note where it is and keep children and pets away from those areas.
Use a test kit or a lab
Hardware stores sell lead test swabs. Follow the kit directions on a small spot and don't sand to get a sample. For a firmer answer, a lab test or a lead inspector can confirm.
Damp-wipe dusty surfaces
Dust sills and trim with a damp cloth rather than a dry one or a standard vacuum, which can put fine dust back in the air.
Ask your local health agency
State and local health departments often have guidance on lead testing and safe work in older homes. A quick call can tell you what's available where you live.
When to call a pro
Call a pro when the house predates 1978 and the job involves sanding, or when the paint is already peeling or chipping. If a test comes back positive, the work may need a contractor who follows lead-safe practices. Removing lead paint is not a casual DIY job, and a handyman will tell you honestly whether the job fits their work.
One Call Handyman Repairs can line up an independent, vetted handyman to look at the walls. The estimate is free, the handyman confirms the price before any work starts, and you approve it first. Licensing is the handyman's own and varies by state, so ask your local building department or state licensing agency what applies to your project.

What the technician will do
- Talk through the house's age and paintThe technician will ask when the home was built and look at the surfaces. If lead is a possibility, they'll explain how that affects the prep and whether testing comes first.
- Prep the room properlyFurniture is moved and covered, holes are patched, and surfaces are prepared and caulked. When lead is not a concern, that includes sanding.
- Seal stains before paintingStains are sealed with stain-blocking primer. A ceiling stain from a leak should have the leak fixed first, since paint won't hold over a damp source.
- Paint and clean upTwo coats go on, cut in by hand at the ceilings and trim, and the room is cleaned up afterwards.
Related questions
- Can I just paint over old lead paint without sanding?
- Intact paint is often painted over after a gentle cleaning, which avoids creating dust. But if the paint is peeling or flaking, that needs a lead-safe approach first. Have the surface looked at before deciding.
- What if my home was built after 1978?
- Lead paint is much less likely, but sanding dust is still worth controlling. Use damp methods where you can, wear a dust mask and keep the room sealed off from the rest of the house.
- Does a test kit give a final answer?
- A swab kit is a useful first check, but it only tests the spot you swab, and a result can depend on how many layers it reaches. A lab test or a lead inspector gives a more reliable answer.
- Can a handyman paint my older home?
- Often yes, especially when the paint is intact and the prep doesn't need heavy sanding. Call (888) 471-8212 or send a request through the website, and a handyman can look at the job and give a free estimate.
