You can’t see it. You can’t smell it. But it could be putting your family or workers at risk — every single day.
Lead is toxic.
It’s especially dangerous to young children and pregnant women. And it still exists in millions of homes and buildings built before 1978 — including 80% of properties in many California neighborhoods.
15 Years of Happy Clients & Counting
Lead poisoning can cause irreversible brain damage in children.
Even low levels of exposure can lower IQ, impact learning, and increase behavioral issues.
One child’s lead exposure can cost families tens of thousands in medical care, special education, and long-term support.
Contractors can’t legally disturb painted surfaces in pre-1978 buildings without clearance testing.
DIY kits often give false results — and they don’t hold up for permits, lawsuits, or disclosures.

If your home or building was built before 1978, there’s a strong chance lead is present — especially in paint, dust, or soil. If you’re planning renovations, selling, or just want peace of mind, testing is a smart (and sometimes required) first step.
We test paint (peeling or intact), surface dust (like windowsills and floors), and outdoor soil. We also offer clearance testing after remediation or renovations.
In California, yes — especially for pre-1978 properties. Many contractors won’t start work until you’ve shown certified testing results.
Most aren’t. They miss important spots, give false results, and don’t meet legal or permit standards. Our state of the art testing equipment provides accurate results.
Standard turnaround is 2–3 business days. Need results faster? Just ask — rush service is available.
