If your home was built before 1990, there is a possibility that there might be some lead paint on the walls. Lead was commonly used in residential paints for many decades because of its durability, but now we know that lead exposure can pose serious health risks.
Having lead-based paint in your home doesn't automatically mean you're in danger, so there is no need to panic if you discover there is lead-based paint somewhere in your house. Before starting a home project, understanding where lead paint can be commonly found and how to identify it can help you make informed decisions.
Where you might find lead paint in your home?
Lead-based paint was widely used in homes until the late 1970s, although some products remained available after that. If your home was built before 1990, it might be a good idea to consider the possibility of lead-containing materials before disturbing any painted surfaces in your home.
Lead-based paint can be found on both interior and exterior surfaces, including:
- Window frames and sills
- Doors and door frames
- Baseboards and trim
- Walls and ceilings
- Stair railings
- Exterior siding
- Porches and decks
- Garages and sheds
Can you tell if there is lead in the paint by just looking at it?
No, you can't. Lead-based paint looks just like any other paint, so even if it appears to be in good condition, you won't know if it contains lead or not until you get it tested.
Some older painted surfaces may show signs such as peeling, cracking, or chipping, but these signs do not automatically mean it’s old, lead-containing paint, simply that it is facing wear and tear throughout its lifespan.
Why is lead paint dangerous?
Lead paint can become hazardous when it deteriorates and peels or when it is disturbed (for example when it is sanded or scraped) as lead dust is made up of microscopic airborne particles.
Lead dust can settle on floors, furniture, toys, and other household surfaces, where it can easily be inhaled or ingested. Small children are particularly vulnerable because they often put their hands or objects into their mouths.
Long-term lead exposure can affect the brain, nervous system, kidneys, and other organs. This is why it's really important to handle it properly and safely.
What's the best way of testing for lead?
The most reliable way to determine whether your home contains lead-based paint is through professional testing. A qualified consultant can collect samples of the suspected material and present the results after laboratory analysis.
While “Do it yourself” (DIY) lead test kits are available for anyone to purchase, they might not provide the level of accuracy a professional test can. A consultant is also able to explain the results and discuss the best next steps with you.
Should you always remove lead paint?
Not always. If lead-based paint is in good condition and is not likely to be disturbed, it may be safe to leave it in place and monitor its condition.
However, professional lead abatement is often recommended when:
- The paint is peeling, chipping, or deteriorating.
- Renovations or demolition will disturb painted surfaces.
- Young children or pregnant women regularly occupy the building.
- Lead hazards have been identified during an inspection.
Conclusion
If you think your home may have lead-based paint, it's always best to have it evaluated by a qualified professional before starting any work. Proper testing and safe lead abatement can help protect your home and everyone in it.
