Before:
The home had no radon system in place and tested between 4–5 pCi/L, with no sump or water drainage infrastructure available.

After:
A two-pipe system was installed—one for the foundation and another for the slab—strategically placed and routed out through the left side of the house. The result: effective radon mitigation with no unnecessary cosmetic disruption.

Explore the significant impact of our radon mitigation efforts in a split-level Stamford home through our before and after gallery. Facing a radon level of 7.4, we implemented a two-pipe system that effectively reduces radon levels by drawing radon from both the slab and the unfinished basement. After photos illustrate the discreet external piping installation around the fireplace and ascending the home's peak, showcasing our ability to enhance safety without compromising the home's aesthetic.

The radon level measured 5.1 pCi/L, which is slightly above EPA action level.

A single-pipe system will be installed to mitigate radon to safe levels. The system will use standard 3” Schedule 40 PVC routed from the foundation slab up through the side of the home or attic, depending on structural layout and power access.

Before photos will capture the foundation area prior to drilling, and external areas for pipe exit, while after photos will show the sealed suction point, fan placement, and final exterior vent termination. Due to the Cape style and small footprint, routing is expected to be direct and clean.

Before: Two-pipe radon system poorly located at the front of the house with one extraction point covered in plastic.
After: Extraction repaired, third pipe added, and system relocated to the back of the house—away from bedrooms, per homeowner request. Crawl space encapsulated (12x42 area) for long-term control.

This property is not yet at the installation stage, so there is no "after" yet—but this is a perfect case where pre-planning is key. The contractor, Adrian Dognin, explained that part of the house has been gutted to the studs, while another section (with a crawlspace underneath) remains intact. Radon levels have reportedly tested high, though exact numbers are not available, and Adrian suspects that testing may not have included the crawlspace.

The home is currently being renovated as part of a sale process, though the homeowner, Lynne, has not yet set a closing date. She is working closely with Adrian to prepare the property for safe occupancy or transfer. This consultation is meant to assess the entire property thoroughly and plan a future system that accounts for both slab and crawlspace areas.
