Lead paint in homes built before 1978 poses serious health risks, especially for children and adults. This guide explains how to test for lead contamination, identify hazards, and take action to ensure your home is safe. Proper testing and remediation can protect your family’s health and prevent complications.
Understanding Lead Paint Risks in Older Homes
Homes constructed before 1978 have a high likelihood of containing lead-based paint. The older the home, the greater the risk—houses built before 1940 have an estimated 87% chance of containing lead paint, while those built between 1960-1978 still carry a 24% risk.
Lead becomes dangerous when paint deteriorates, creating dust and chips that can be inhaled or ingested. Children are particularly vulnerable because their developing nervous systems absorb lead more readily than adults. Even small amounts of lead exposure can result in irreversible damage.
The Environmental Protection Agency (EPA) has established strict guidelines for lead testing and remediation, making it essential to understand both the risks and your options for addressing them.
Common Locations of Lead Paint
Lead paint wasn’t randomly applied throughout homes—it was commonly used in specific areas where durability and washability were priorities. Knowing where to look can help focus your testing efforts.
High-Risk Areas:
- Window sills, frames, and trim
- Doors and door frames
- Stair railings and balusters
- Kitchen and bathroom cabinets
- Exterior siding and trim
- Porches and decks
Medium-Risk Areas:
- Interior walls, especially in kitchens and bathrooms
- Baseboards and crown molding
- Built-in furniture and shelving
- Radiators and pipes
Pay special attention to areas where paint shows signs of wear, chipping, or peeling. These deteriorated surfaces present the highest immediate risk for lead exposure.
Step-by-Step Guide to Lead Testing
Testing your home for lead doesn’t have to be overwhelming. Following a systematic approach ensures you don’t miss potential hazard areas.
Preparation Steps:
- Document all painted surfaces in your home, noting their condition
- Take photographs of areas showing paint deterioration
- Gather necessary testing supplies or contact certified professionals
- Plan your testing schedule to minimize disruption
Testing Process:
Begin with the highest-risk areas identified earlier. If you’re using DIY test kits, carefully follow the manufacturer’s instructions. Most kits require you to make small cuts in the paint surface and apply testing chemicals.
For each surface, test multiple layers of paint, as lead may be present in underlying coats even if the topcoat is lead-free. This is particularly important in homes that have been repainted multiple times.
Keep detailed records of your testing, including locations, dates, and results. This documentation will be valuable if professional remediation becomes necessary.

Professional Testing Versus DIY Kits
Both professional testing and DIY kits have their place in lead detection, but understanding their differences helps you choose the right approach.
DIY Test Kits:
Home test kits are readily available and cost-effective for initial screening. They typically use chemical indicators that change color when lead is present. However, these kits have limitations—they may not detect lead in all paint layers and can produce false negatives.
EPA-recognized test kits are more reliable than generic versions. Look for kits that meet EPA standards and follow instructions precisely for accurate results.
Professional Testing:
Certified lead inspectors use X-ray fluorescence (XRF) analyzers or collect paint chip samples for laboratory analysis. Professional testing provides more accurate and comprehensive results, including lead concentration levels.
Professional testing becomes essential when DIY tests indicate lead presence, when selling a home built before 1978, or when planning renovation work. Many situations legally require certified testing, particularly in rental properties or commercial buildings.
Consider professional services similar to asbestos inspections, like those in Salt Lake City, where certified experts provide thorough assessments and detailed reports that meet regulatory requirements.
Interpreting Test Results
Understanding your test results determines your next steps and helps prioritize safety measures.
Positive Results:
A positive test indicates lead presence but doesn’t automatically mean immediate danger. The risk level depends on the paint’s condition, location, and lead concentration.
Intact lead paint in good condition poses minimal immediate risk. However, any lead paint that’s chipping, peeling, or subject to friction (like window sills) requires prompt attention.
Negative Results:
Negative results suggest no detectable lead in the tested area. However, remember that testing is surface-specific—negative results in one area don’t guarantee the absence of lead elsewhere in your home.
Inconclusive Results:
Some tests may produce unclear results. When this happens, professional testing can provide definitive answers and peace of mind.
Remediation Options and Safety Measures
Once you’ve identified lead hazards, several remediation approaches can make your home safe.
Interim Controls:
These temporary measures reduce lead exposure while you plan permanent solutions:
- Regular cleaning with HEPA vacuums
- Maintaining good paint condition through gentle repairs
- Installing window well liners to contain paint chips
- Creating barriers to prevent access to lead-hazardous areas
Permanent Solutions:
- Encapsulation: Covering lead paint with special coatings that prevent deterioration
- Enclosure: Installing new surfaces over lead paint, such as drywall or paneling
- Removal: Complete paint removal by certified professionals using safe work practices
Never attempt DIY lead paint removal through sanding, scraping, or heat guns. These methods create dangerous lead dust that can contaminate your entire home.
Special Considerations for Assisted Living
Lead testing becomes particularly important when considering housing options for elderly family members. Assisted living facilities like those in Layton must comply with strict safety standards, but older homes being converted or private residences may require additional scrutiny.
Seniors face increased health risks from lead exposure due to age-related health conditions and medications that may increase lead absorption. When evaluating assisted living options or aging-in-place modifications, comprehensive lead testing should be part of your safety assessment.
Resources for Lead Abatement and Further Information
Several resources can help you navigate lead testing and remediation:
Government Resources:
- EPA’s National Lead Information Center: 1-800-424-LEAD
- State and local health departments often provide testing services
- HUD offers grants for lead hazard reduction in eligible homes
Professional Services:
- Certified lead inspectors and risk assessors
- EPA-certified renovation contractors
- Local environmental consulting firms
Educational Materials:
The EPA’s “Renovate Right” pamphlet provides essential information for anyone planning home improvements in pre-1978 houses.
Many utility companies and community organizations offer free or low-cost lead testing programs. Contact your local health department to learn about available resources in your area.
Conclusion
Testing for lead in older homes is essential for your family’s safety and preserving your home’s value. Focus on high-risk and deteriorated areas first, and document your process. Whether DIY or professional, taking action is key. Lead hazards are manageable with the right steps, protecting your family’s health long-term.
