RADON TESTING & MITIGATION — WATERBURY, CT
New Haven County sits in the EPA's highest radon-potential zone. If your home tests at or above the action level, a properly installed mitigation system typically fixes it in a single day.
SERVICES
Sub-slab depressurization systems that pull radon from beneath your foundation and vent it safely above the roofline — the fix the EPA recommends for elevated homes.
How mitigation works →Short-term and real-estate-transaction testing with clear results in days. Know your number before you buy, sell, or finish a basement.

Radon is a colorless, odorless radioactive gas released by the bedrock under New Haven County. It seeps into basements and slabs through cracks and sump pits, and it's the second-leading cause of lung cancer in the U.S. according to the EPA — about 21,000 deaths a year.
The good news: it's one of the most solvable problems in home safety. A single test tells you where you stand, and a mitigation system reliably drops most homes well below the action level.

HOW RADON GETS IN
Radon is produced continuously by the natural breakdown of uranium in the rock and soil beneath New Haven County. Because it's a gas, it moves through the ground toward areas of lower pressure — and in winter especially, that low-pressure zone is the inside of your house. Heated air rising through a home creates a gentle vacuum at the foundation (the "stack effect") that actively pulls soil gas indoors.
The entry points are ordinary construction details, not defects: the gap between the slab and foundation wall, cracks in the basement floor, sump pits and floor drains, utility penetrations, and the exposed soil in crawl spaces. Even homes on slabs with no basement draw in soil gas — the slab itself sits directly on the source.
That's also why two houses on the same street can test completely differently. Radon levels depend on the soil under one specific footprint, the foundation's construction, and how the house breathes. A neighbor's low reading tells you nothing about yours, and vice versa.
Winter, when closed windows and heating amplify the stack effect. That's why a winter test is your home's true worst case — and why a marginal summer reading is worth retesting in the cold months.

COMMON QUESTIONS
The EPA recommends fixing your home at 4.0 pCi/L or higher, and considering action between 2.0 and 4.0. There's no known fully safe level, so lower is always better.
Most residential systems fall in the $900–$2,500 range depending on foundation type and layout. You'll get an exact quote before any work starts.
Typically one day. The system runs continuously afterward and a follow-up test confirms the fix.
Real estate timelines are the most common reason people call. Short-term tests take about 48 hours in the home; call and we'll work with your closing schedule.
