If your Dallas-Fort Worth home was built before 1978, there is a real chance lead-based paint is still hiding under newer layers on your walls, trim, windows, and doors. A 2024 sale or a weekend remodel won’t make it go away — and the moment you sand, scrape, or demolish that surface, you create lead dust that’s hazardous to your family, your contractors, and anyone else in the home.
This post explains when a DFW homeowner actually needs lead testing, what the federal rules require, and why skipping the inspection before a renovation is one of the most expensive shortcuts you can take.
Why 1978 Is the Magic Number
The U.S. banned lead-based paint for residential use in 1978. Homes built before that year — and we have a lot of them in older Dallas neighborhoods like M Streets, Oak Cliff, Munger Place, and parts of East Dallas, Fort Worth’s Fairmount and Ryan Place, Plano’s original townsite, Arlington’s historic core, Irving’s Heritage District, and almost every postwar Garland or Mesquite home — are presumed to contain lead paint unless tested and proven otherwise.
The older the house, the higher the likelihood and the higher the lead concentration. Homes built before 1960 are the riskiest, but anything pre-1978 should be tested before any disturbance.
When DFW Homeowners Should Get Lead Testing
You should schedule lead testing before you:
- Repaint, scrape, or sand any painted surface in a pre-1978 home
- Replace windows, doors, or trim in an older property
- Renovate a kitchen or bathroom that has original paint or millwork
- Demolish walls, soffits, or any painted structural element (see our notes on safe demolition practices)
- Buy or sell an older home — a clean lead report is a legitimate selling point
- Move children under 6 or a pregnant family member into a pre-1978 house
You should also test if you notice peeling, chipping, chalking, or “alligator” paint anywhere in the home — these are the surfaces actively shedding lead into household dust.
The Federal Rule Most Homeowners Don’t Know About
The EPA’s Renovation, Repair, and Painting (RRP) Rule requires any contractor working on a pre-1978 home to be lead-certified and to follow lead-safe work practices when disturbing more than six square feet of interior painted surface (or 20 square feet exterior). That means your handyman, your window installer, your painter, and your demo crew all need to be properly certified — or they’re working illegally and putting your family at risk.
Getting a lead test done first answers the question cleanly. If the surface tests negative, the RRP rule doesn’t apply and your project moves faster. If it tests positive, you know exactly what containment and lead paint removal work needs to happen — and you can hire the right people the first time.
What the Lead Testing Process Looks Like
A professional lead inspection in the DFW area typically includes:
- Visual assessment — identifying deteriorated paint and high-friction surfaces (windows, doors, stair treads) most likely to generate lead dust.
- XRF analysis — a handheld X-ray fluorescence device reads lead content directly through the paint layers, non-destructively, surface by surface.
- Paint chip or dust wipe sampling — for surfaces XRF can’t read accurately, small samples go to a certified lab.
- Soil sampling — exterior soil near old painted siding is often a hidden source, especially in homes where the exterior has been scraped or pressure-washed over the years.
- A written report — documenting each tested surface, the result, and recommendations for any positive findings.
What Happens If You Skip Testing
The shortcuts are expensive in three ways:
Health costs. Lead poisoning in children under 6 causes permanent neurological damage at exposure levels far below what an adult would feel. A renovation that releases lead dust into a family home can cause elevated blood lead levels in weeks. The CDC’s blood lead reference value is 3.5 µg/dL — and pediatricians in Dallas County are required to report cases.
Legal and insurance costs. If you sell a pre-1978 home and fail to disclose known lead hazards, you’re violating federal disclosure law (the Residential Lead-Based Paint Hazard Reduction Act). Your homeowners insurance generally does not cover claims tied to lead contamination from improper renovation.
Remediation costs. Cleaning up a home where uncontained sanding has spread lead dust into HVAC ducts, carpet, and soft furnishings is dramatically more expensive than testing and abating a known surface in the first place. We’ve seen DFW jobs go from a $1,500 controlled removal to a $20,000+ whole-home decontamination because the homeowner sanded first and asked questions later.
Lead Often Travels With Other Hazards
Older DFW homes that have lead paint frequently have other environmental concerns layered into the same renovation. Pre-1980 homes may have asbestos in floor tiles, popcorn ceilings, pipe insulation, or drywall joint compound — see our guide on popcorn ceiling asbestos and asbestos in drywall. If you’re already opening up walls, bundling lead testing with asbestos testing saves money and ensures nothing surprises you mid-project.
Get the Test Before You Start the Project
If you’re a DFW homeowner planning a spring or summer renovation on a pre-1978 property — or you’ve just closed on an older home and want to know what you’re working with — schedule a lead inspection before the first hammer swings. Contact Superior Environmental Services for licensed lead testing across the Dallas-Fort Worth metroplex. We can usually get a technician to your property within 24 hours.
