Radon Information Before & After Photos

Before:
This Cape Elizabeth home had elevated radon levels of around 10 pCi/L on the first floor and an existing passive radon system in place. The home included two spray-foamed crawl spaces, and the homeowner wanted to determine whether activating the passive system with additional extractions would effectively reduce levels without installing a full sub-slab system.

Prior to installation, we coordinated access so we could enter the home without interruption, as the client might have been on a call. We performed communication testing in both crawl spaces to confirm airflow and system viability, with plans to reseal all areas afterward.

After:
We successfully activated the passive radon system using a dual extraction setup, with one extraction point in each spray-foamed crawl space. Both extractions were carefully pulled from under the spray foam, rather than from beneath the slab, and then tied cleanly into the existing passive system.

All crawl spaces were properly resealed after testing and installation. The final setup allowed the passive system to effectively pull from both crawl spaces, improving overall radon reduction potential while preserving the integrity of the spray foam and structure.

The installation was clean, coordinated, and worked exactly as planned—providing a smart, efficient radon solution for the home.

Another Cape Elizabeth property protected with thoughtful design and precise execution.

Before:

Michelle G., a real estate agent in Lewiston, Maine, reached out looking for a fast solution for her client after radon air testing came back at 17.2 pCi/L. With an active transaction underway, timing was critical and everyone needed a clear plan to keep the sale moving.

After:

We installed a radon mitigation system on an accelerated timeline, coordinating closely with all parties to minimize delays. The system was completed cleanly and efficiently, bringing the home back within acceptable levels and allowing the transaction to proceed smoothly.

Everyone involved was relieved and satisfied with how quickly the issue was handled. Another Lewiston home protected — and another closing supported with the right solution at the right time.

Before:

Michelle G., a Lewiston real estate agent who frequently trusts us with her transactions, reached out again for another client after an air radon test showed 8.7 pCi/L. The home had a full concrete basement, partially finished, with a walkout to the backyard. The layout was challenging — a wraparound deck and multiple windows limited exterior routing options. Michelle needed a quick, professional solution to keep the transaction moving.

After:

We evaluated the structure and found a way to safely route the system by carefully working out of a corner of the finished basement and wrapping the piping around the home to an area not obstructed by decks or windows. Despite the tight constraints, the installation was clean, discreet, and effective.

The system looked sharp, performed properly, and satisfied everyone involved in the sale. Michelle once again trusted us to deliver under pressure, and the result was a smooth, professional mitigation that kept the deal on track.

Another Lewiston home protected — and another successful collaboration built on trust.

Before:
About five years ago, radon air testing in Abe L.’s home in Greene, Maine showed levels ranging from 6.0 to 8.0 pCi/L. While the home remained occupied, those readings stayed a concern over time, and Abe decided it was time to install a permanent mitigation system to protect the space long-term.

After:
We installed a radon air mitigation system designed specifically for the home’s layout. The installation was clean, efficient, and visually well integrated with the structure. The finished system looked sharp, operated properly, and provided the homeowner with confidence that the issue had been addressed.

Another Greene home upgraded with a professional solution and long-term peace of mind.

Maine Radon & Environmental was hired to install a radon mitigation system in this Falmouth home. Client was concerned about there levels and hired Maine radon & environmental to take care of this issue. Another happy client!!
