What owners of older Seattle-area homes should know to keep their family safe before, during, and after the paint job.
Painting a house with lead paint is something many homeowners in Seattle and across King County face, often without realizing it. Many older homes here were built before 1978, and lead paint in a house from that era is common. It is also manageable with lead-safe painting, because most of the risk comes from how old paint is disturbed. This post covers how to tell if you have it, when painting over it is fine, how to protect your family during the job, and what to watch for when you hire a painter.
TL;DR: Is It Safe To Paint a House With Lead Paint?
Yes, a house with lead paint can be painted safely. The care goes into the prep, because disturbed old paint is where the risk comes from.
- Find out first: a home built before 1978 may have lead paint, and testing by a certified inspector is how you know.
- Painting over: intact, well-bonded lead paint can be painted over, while peeling paint has to be stabilized first.
- Leave prep to a certified firm: scraping, sanding, and stripping are the steps that create lead dust.
- Protect the family: keep children, pregnant family members, and pets out of work areas until cleanup is checked.
When Lead Paint Becomes a Risk
Painting a house with lead paint can be done safely. The danger is the dust and chips that come off old paint when it is scraped, sanded, or otherwise disturbed, and intact paint left alone is a much lower risk. On a home built before 1978, that prep work belongs with a certified lead-safe firm, which controls the work so exposure stays low.
Intact lead paint in good condition, with no peeling, chipping, or bubbling, carries a lower risk than paint that is already failing. The surfaces that see the most friction are worth watching: windows, doors, and trim that rub or impact tend to generate fine particles even without a paint job underway.
Young children and pregnant people are the most vulnerable to lead dust. The main risk is swallowing or inhaling chips or dust, not being near intact painted walls. If either is in your household, keep them out of any work areas until those areas are cleaned and checked.
Living in a house with intact lead paint is generally manageable, as long as the paint stays in good condition and is not disturbed. Once a project calls for scraping, sanding, or stripping old paint, that work should be completed by a crew trained in lead-safe painting for older homes.
How to Tell if Paint Is Lead-Based
You cannot determine if lead paint exists by looking at it. The color, sheen, and texture of lead paint are indistinguishable from non-lead paint, so visual inspection alone is not a reliable method.
The most useful starting point is the age of your home. Lead paint was banned for residential use in 1978, so homes built before that year may have it on original surfaces. Subsequent repainting does not settle the question. Lead paint can sit under newer coats, especially on trim, windows, doors, porches, and railings, where multiple layers accumulate over decades.
Two signs are worth noticing, though neither is proof on its own. First, many layers of old paint on a surface, particularly around window frames and doors, suggest the house has been repainted multiple times and earlier coats may predate the ban. Second, a cracking pattern called alligatoring, where the paint surface breaks into small squares resembling reptile scales, is a sign of aged paint on older homes and is worth flagging for testing.
To know for certain whether there is lead paint in your house, testing by a certified lead inspector or risk assessor is the reliable path. Home test kits also exist. A certified inspector can tell you where lead is present and what condition it is in.
If you are planning any work that will disturb painted surfaces in a pre-1978 home, testing before the job starts helps you and your contractor make informed decisions about prep and safety measures.
Is It Safe to Paint Over Lead Paint?
Painting over lead paint is generally fine when the existing paint is intact, well bonded, and on a surface that does not see heavy friction. The prep before the new coat goes on is the part that must be handled carefully.
Peeling, chipping, or failing lead paint is a different situation. That paint must be stabilized before a new coat can be applied, and stabilizing it involves disturbing it, which is the step that creates dust and chips.
What Lead Paint Encapsulation Means
Lead paint encapsulation means applying special coatings designed to seal lead paint beneath a durable barrier. These coatings are made for the job and are not the same as a standard repaint. Encapsulation is a recognized approach for intact lead paint, and the lead paint stays in place under the seal rather than being removed.
What the Homeowner Can Reasonably Assess
You can look at your own painted surfaces and notice whether the paint is peeling, bubbling, or chipping. You can observe whether friction surfaces like window sashes show wear. If the paint looks intact and well-adhered across the surfaces you are planning to repaint, that is useful information to bring to a conversation with a contractor.
If you are wondering how to paint over lead paint yourself, the answer depends on the prep. Anything that involves scraping, sanding, or stripping old paint should go to a certified firm, because those steps are where lead dust is created. A homeowner can decide about testing and when to call for help, while certified lead-safe painting covers the prep and paint job on pre-1978 homes.
Keeping Your Family Safe During the Paint Job
The best way to protect your household is to keep children, pregnant family members, and pets out of the work areas until cleanup is finished and confirmed. Lead dust settles on surfaces and can be tracked through a home, so the work zone matters beyond the room being painted.
For exterior work, the perimeter of the house becomes a work zone during prep. Move outdoor toys, play equipment, and garden produce away from the house before prep begins. Soil around the foundation can collect chips and dust during exterior work, so keep children out of those areas during the job. Most lead paint dangers for young children come from dust and chips, and soil is one of the less obvious places they collect.
For interior work, the work area should be sealed off from the rest of the house. Heating and cooling vents should be covered. Plan where your family will be on prep days, since those are the days when old paint is being disturbed.
For anyone who is pregnant, health authorities advise avoiding areas where lead paint is being disturbed. With lead paint and pregnancy, the safest approach is to stay away from the work area on prep days and until the space has been cleaned and cleared. If you have specific health concerns, your doctor is the right resource for personal guidance.
After the job is complete, before the rooms are used again, look for visible dust or chips on windowsills, floors, and horizontal surfaces. A clean job site at the end of each day is a sign that the crew is managing the work responsibly.
Why Older Seattle-Area Exteriors Need Extra Care
The Seattle area’s wet winters and extended damp stretches are hard on old exterior paint. On a pre-1978 home, that means peeling and failing coats are common, and more surface failure means more disturbed paint during prep.
Pressure washing is a standard part of exterior prep in this region. On older homes, what matters to you as a homeowner is that runoff, chips, and debris are being contained during that step and are not ending up in your garden beds or soil. A good crew puts sheeting down to catch that material before the first pass, which matters on a home that may have lead paint.
Exterior work in the Seattle area is also scheduled around dry weather, because paint needs a dry surface to bond and cure. That makes weather part of planning any exterior painting on older homes, and it decides the best time to paint your house exterior in the Pacific Northwest.
What Good Lead-Safe Painters Do on an Older Home
You do not need technical training to judge a painter’s lead-safe practices. Much of the work is visible from the street or the yard.
- Dust control is visible. On old painted surfaces, a good crew works over plastic sheeting, uses wet scraping and wet sanding, and keeps the work area contained.
- Plastic goes down on the ground below exterior work. On a pre-1978 home, chips and debris from the siding or trim land on sheeting, not in the soil or on nearby surfaces.
- Pressure washing runoff is caught. The chips and paint particles that come off an older home during a pressure wash are contained instead of washing into garden beds.
- Torches and high-heat tools stay off old paint. They can release lead fumes, so lead-safe crews leave them out of the job.
- The site is cleaned at the end of every workday. Sills, floors, and the ground are cleared of dust and chips, because cleanup is part of the job.
- Certification is easy to produce. A firm certified in lead-safe painting has the documentation ready when you ask.
What to Remember Before Your Paint Job
For owners of older homes, lead-safe painting comes down to careful prep and process. Find out whether your home has lead paint before you start any project that disturbs old surfaces. Paint over intact lead paint in good condition, and consider encapsulation for stable surfaces.
Leave any work that involves scraping, sanding, or stripping to a certified firm. Keep children, pregnant family members, and pets out of work areas on prep days and until cleanup is confirmed. Know what a responsible job site looks like before the crew arrives.

Frequently Asked Questions
Can you live in a house with lead paint?
Yes. When lead paint is intact and kept in good condition, living in the home is generally manageable. The risk rises when paint begins to peel, chip, or is disturbed by renovation or repair work. Keeping painted surfaces in good condition and addressing wear promptly is the practical approach for occupied homes.
What should I do if my house has lead paint?
Keep the paint intact and in good condition. If you are unsure whether lead paint is present, have the surfaces tested by a certified lead inspector or use a home test kit as a first step. For any work that will disturb old painted surfaces, use a firm that holds lead-safe certification to handle the prep.
Can a house built after 1978 have lead paint?
Much less likely, because lead paint was banned for residential use in 1978. Homes built after that year are unlikely to have lead-based paint on original surfaces.
Should I sand or scrape lead paint myself?
No. Sanding and scraping are the steps that generate lead dust, which is the primary exposure risk. Those tasks are the part to leave to a certified firm. A homeowner can assess surface condition and make decisions about testing, but the physical prep work on a pre-1978 home is where professional handling matters most.
What happens to paint chips and debris after the job?
On a lead-safe job, chips, dust, and debris are contained on protective sheeting throughout the work and collected at the end of each day. The material is removed with the sheeting rather than left on the ground or swept into the yard. How a crew manages cleanup at the end of each workday is one of the clearest indicators of whether the job is being handled responsibly.
