Reducing Radon in Thornton

Located in Adams County, the city of Thornton is classified as Zone 1 based on radon levels from the Environmental Protection Agency's (EPA). This means indoor radon screening levels are likely to exceed the EPA limit of 4 pCi/L; however, not all Thornton homes have radon. To determine if radon mitigation is necessary, homeowners in Thornton should perform long-term, continuous, or short-term radon tests. If your home tests above 4 pCi/L, 5280 Radon Mitigation offers a free estimate for a radon reduction system.

Over the past ten years, 5280 Radon Mitigation has installed more than 10,000 radon fans to provide our neighbors with clean, healthy indoor air. Proudly serving all communities in Thornton, including Cornerstone, Parkside, Woodbridge Station, emerald Estates, Cottonwood Lakes, Cherrywood Park, Hillcrest, Skylake Ranch, Autumn Creek, Colony Park, York Highlands, Star Point, Carriage Hill, Lake Avery Estates, Villages at Hunter Glen, Talon View, and all others.

The 5280 Radon Mitigation Difference

All of our radon reduction systems come with an industry-leading, 5-year warranty. By using only the highest quality materials and our extensive knowledge of Thornton, CO construction practices, we install radon systems that are built to last.

The 5-year warranty covers all warranty issues at no extra cost to you. The radon fans we install come with this generous warranty, but most last 12-15 years and homeowners rarely have to use the warranty. If your fan does go out within the warranty period, we will replace it free of charge.

Lower Radon Levels, Guaranteed

As part of all our radon system installations, we provide a free radon test kit post-installation to monitor the performance of your system. This monitors your radon levels, and we guarantee that the system will keep your radon levels below 4.0pCi/L*. If your radon levels go above 4.0pCi/L after the initial installation, we will come back and fix the system for free.
