Before & After Photos

In areas like Gray, Maine, radon levels can vary, but they often exceed safe limits, posing potential health risks to homeowners. A new homeowner in Gray discovered dangerously high radon levels of 56.2 and 37.2 pCi/L after testing, far above the EPA’s recommended action level. With no existing mitigation system, they turned to Maine Radon & Water for a solution. Our team installed a Sub-Slab Depressurization system with a Premium Radon Fan, completing Field Pressure Extension Testing to ensure a tailored fit for the home. We also installed a custom pedestal pump cover for optimal performance. Now, the homeowner can rest easy knowing their home is safe from radon exposure. If your radon levels are too high, don’t wait—schedule your consultation today!

Radon can enter your home through well water, posing a serious health risk when high levels are released into the air during everyday water use.

In Raymond, Maine, the homeowner faced radon levels in their well water that exceeded the state's safety guideline by more than tenfold, prompting urgent action before finalizing their home purchase. Maine Radon & Water Treatment was chosen for their expertise in comprehensive radon mitigation. The project involved installing a complete system to address the issue, including a softener, salt unit, neutralizer, air raider, sediment filter, and sub-slab depressurization. Adjustments were made to optimize performance, replacing the dab pump with an expansion tank and internal pump for maximum efficiency. This tailored solution brought peace of mind and improved water safety for the new home.

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.

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.
