Radon Information Before & After Photos

Client had excessive moisture in basement. Problem solved. Sump install and sani dri capped off with cleanspace enclapsulation

Sub membrane radon mitigation job using clean space encapsulation. This will create negative pressure under the clean space which will help reduce radon air levels. This install is topped off with a premium fan cover and sani dri dehumidifier.

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.
