Maine Radon & Water Treatment Before & After Photos

Before:

Laren C. in Gray, Maine reached out after radon testing revealed elevated levels of 18.9 and 18.6 pCi/L. The home required a mitigation plan that would effectively reduce levels while working with the existing basement layout. During evaluation we confirmed the subfloor conditions were favorable, with dry sand beneath the slab, which allowed for strong sub-slab communication.

Laren considered two installation options for routing the system — either exiting through the siding or core drilling through the concrete foundation. The homeowner also took initiative by spray-foam sealing behind the well area prior to installation and planned to install an outlet for the fan connection.

After:

Laren ultimately chose the concrete penetration option, and we installed a sub-slab depressurization system using an RN2 fan. The system included a core-drilled penetration through the basement wall, allowing for a clean and efficient exterior run. The dry sub-slab conditions allowed the system to communicate well beneath the slab and perform exactly as intended.

The finished installation looked professional and delivered reliable radon reduction for the home. Another Gray, Maine home protected with a clean installation and a homeowner actively involved in the solution.

Before:

Marjorie K.’s home in Gray, Maine tested at 42.6 pCi/L, well above recommended levels. The home included radiant floor heating, which required extra care when determining the safest location for the sub-slab penetration. Because radiant tubing can run through the slab, we evaluated the area carefully to avoid damaging the heating system.

Our initial plan was to install the suction point in the back corner near the rear doors, but we prepared an alternate route if the radiant layout prevented drilling in that corner. In that case, the pipe could have been run from near where the radiant lines entered the floor and routed across the ceiling to exit through the same wall. An IR heat inspection helped confirm the safest drilling location.

After:

The mitigation system was installed successfully while working around the radiant heating system. Power was supplied from an outlet located near the homeowner’s computer area, keeping the installation clean and efficient. The system exited near the rear corner of the home, maintaining a neat exterior appearance.

The installation was completed in approximately four hours, and the final setup looked professional and performed exactly as intended. Another Gray, Maine home protected with a carefully planned installation that respected the home’s radiant heating system while delivering effective radon reduction.

Maddison L.’s home in Gray, Maine had concerns with both radon in the air and radon in the water. Air testing showed radon levels averaging 8.9 pCi/L with a maximum reading of 11.7 pCi/L, while water testing revealed radon in water at 7,670 pCi/L and uranium at 31 µg/L, which required treatment to ensure safe household water.

With both air and water needing attention, the home required a comprehensive solution that would address multiple sources of radon exposure.

After:

We installed an Airwell radon-in-water mitigation system to remove radon gas from the water supply, along with a 1054 Evolve mixed-bed filtration unit using anion and zeolite media to address additional water quality concerns. To treat the radon present in the air, we also installed a sub-slab depressurization system.

The result was a fully integrated setup designed to treat both the home’s air and water sources effectively. The installation was clean, organized, and tailored to the home’s layout, giving the homeowner a complete solution and long-term peace of mind.

Another Gray, Maine home now has safer air, cleaner water, and a professionally installed system designed to perform for years to come.

The client was told they could not have a radon mitigation system installed due to high water levels. The problem was solved by adding a 1/2 sump and sub-slab radon system—another happy client.
