Lead paint safety is a critical concern when painting older homes built before 1978, when lead-based paint was banned for residential use in the United States. Millions of homes across Minnesota still contain lead paint on their exterior surfaces, creating potential health hazards during renovation and repainting. At Weatherguard Construction, we have 25+ years of experience as a family-owned exterior painting specialist, and we are EPA Lead-Safe Certified, protecting homeowners and families across Stillwater, Woodbury, and Minneapolis.
Understanding Lead Paint Risks
Health Dangers of Lead Exposure
Lead is a toxic heavy metal that poses serious health risks, especially to children under six and pregnant women. Lead exposure can cause developmental delays, learning difficulties, behavioral problems, and organ damage in children. In adults, lead exposure causes high blood pressure, kidney damage, nervous system damage, and reproductive problems.
During exterior painting preparation — scraping, sanding, and power washing — lead paint is disturbed and released as dust and chips that contaminate the surrounding soil and air. Without proper safety measures, this lead-contaminated debris can be tracked into the home, inhaled by workers and residents, and ingested by children playing in contaminated soil.
How Common Is Lead Paint in Minnesota?
Any home built before 1978 may contain lead paint. Homes built before 1950 are almost certain to have lead paint, as it was the standard formulation for exterior use during that era. Many beautiful older homes in Stillwater and the surrounding St. Croix Valley, with their Victorian and Craftsman architecture, date to this period and contain multiple layers of lead paint on their exteriors.
EPA Regulations for Lead Paint
The RRP Rule
The EPA's Renovation, Repair, and Painting (RRP) Rule requires that all firms performing renovation, repair, or painting projects that disturb lead-based paint in homes built before 1978 be EPA-certified and use specific lead-safe work practices. This federal regulation applies to all contractors, including painters, and carries significant penalties for non-compliance.
Certified Firm Requirements
Contractors must be EPA Lead-Safe Certified, which requires specific training, adherence to lead-safe work practices, and proper documentation. Hiring a non-certified contractor to paint a pre-1978 home is not just risky — it may be illegal if lead paint is disturbed during the project.
Homeowner Responsibilities
While the RRP Rule applies to contractors, homeowners should understand their responsibilities. If you hire a contractor to paint your pre-1978 home, ensure they are EPA Lead-Safe Certified. Ask for their certification number and verify it through the EPA's online database. Weatherguard Construction is proud to maintain our EPA Lead-Safe Certification and follows all required protocols on every pre-1978 project.
Lead-Safe Work Practices for Exterior Painting
Testing for Lead
Before any paint preparation begins on a pre-1978 home, testing for lead paint is recommended. Two primary testing methods are available: EPA-recognized test kits that provide instant results, and laboratory analysis of paint chip samples that provides definitive results. Weatherguard Construction can arrange lead testing as part of our project planning process.
Containment
Lead-safe exterior painting requires containment measures to prevent lead dust and chips from contaminating the surrounding area. This includes covering the ground with heavy plastic sheeting extending at least 10 feet from the work area, sealing windows and doors to prevent contamination from entering the home, and posting warning signs around the work zone.
Safe Removal Methods
Lead paint should never be removed using open-flame burning, high-temperature heat guns above 1,100 degrees, or uncontrolled dry sanding and scraping. Safe removal methods include wet scraping, wet sanding with HEPA vacuum-equipped sanders, chemical strippers, and low-temperature heat guns with proper ventilation and containment.
HEPA Vacuum and Cleanup
All work areas must be cleaned using HEPA (High-Efficiency Particulate Air) vacuum equipment that captures lead dust particles. Standard shop vacuums do not filter lead particles and actually redistribute them into the air. After HEPA vacuuming, all surfaces are wet-wiped and visually inspected for remaining debris.
Waste Disposal
Lead paint chips, dust, contaminated plastic sheeting, and other debris must be disposed of according to local and federal regulations. This waste is classified as hazardous and cannot be disposed of in regular trash. Proper disposal adds to project costs but is both legally required and ethically necessary.
Encapsulation: An Alternative to Removal
What Is Encapsulation?
Rather than removing lead paint, encapsulation involves covering it with a specially formulated coating that seals the lead paint in place, preventing it from releasing dust or chips. EPA-approved encapsulants bond to the existing surface and create a durable barrier over the lead paint.
When Encapsulation Works
Encapsulation is an effective strategy when the existing lead paint is in relatively good condition — intact, not peeling, and not heavily chalking. If the surface is prepared properly and the encapsulant is applied correctly, it provides a safe, cost-effective alternative to full lead paint removal.
When Removal Is Necessary
If lead paint is peeling, flaking, heavily chalked, or failing, removal is necessary before repainting. Encapsulants cannot bond to loose or failing paint, and applying them over deteriorated surfaces leads to premature failure. Our team evaluates each surface and recommends the appropriate approach.
Choosing a Lead-Safe Painting Contractor
When painting a pre-1978 home, choose a contractor who is EPA Lead-Safe Certified, has documented experience with lead paint projects, uses proper containment and HEPA equipment, provides a written lead-safe work plan, and follows all cleanup and disposal regulations.

Frequently Asked Questions
How do I know if my home has lead paint?
If your home was built before 1978, it may contain lead paint. Homes built before 1950 almost certainly do. The only way to confirm is through testing — either an EPA-recognized home test kit or laboratory analysis of paint chip samples. Weatherguard Construction can arrange professional lead testing as part of your project.
Can I paint over lead paint without removing it?
Yes, in many cases. If the existing lead paint is in good condition — intact, not peeling or chalking — it can be safely painted over or encapsulated. This approach is often safer than removal because it avoids disturbing the lead paint. However, any loose or failing paint must be removed using lead-safe practices before recoating.
Is it safe to power wash a house with lead paint?
Power washing a house with lead paint without proper containment is dangerous and may violate EPA regulations. The high-pressure water creates lead-contaminated spray and runoff that contaminates soil and water. Lead-safe power washing requires ground containment, water collection, and proper disposal of contaminated water.
How much more does lead-safe painting cost?
Lead-safe exterior painting typically costs 20% to 40% more than standard painting due to containment setup, specialized equipment, careful work practices, and proper waste disposal. While the additional cost is significant, it protects your family's health and ensures legal compliance. Weatherguard Construction provides transparent pricing that includes all lead-safe requirements.
