This home radon levels measured over a whooping 50 pCi/L. I mean there are still higher levels out there, but can you imagine that amount of radon exposure daily? I guess not. The clients had a home monitor, and they barely checked it. When the time came, they heard the news about radon, they were so worried. They just moved in a month ago with a 10-month-old baby girl. This was a 5-point system with the radon fan out the north wall behind their A/C unit.
This home had radon levels of 6.8 and a mostly-finished basement. The client was being proactive and vocal in the event of the house being sold in the future so a radon mitigation is one of his priorities to have done. They already have an ERV/HRV and electronic air filter. The sump pit with interior drain tile on front wall of house. They were a nice couple with two friendly dogs. I guess one will nip at your pants but they kept them leashed most the time I was there! Haha!
The clients needed an additional passive active system, counting this as their 2nd radon mitigation system. They loved their previous one that was installed by us and requested this be installed on the other side of the fence (basement).
The client made a radon test, and levels were around 8 by her treadmill. She had a multilevel basement, so the team needs one point in lowest level and one thru wall for living room/work out room. The Team Lead told her since interior tile we could consolidate points and use less PVC, but if the client wants to put point in the sump - the team will go for it, will just need a couple more sticks of PVC but not coring thru floor. She also has a couple of dogs and hasn't had ducts cleaned. We advised her about our air duct cleaning service, and she was interested!
Originally anticipated this home as a quick radon project, but discovered two sizable, well-maintained crawl spaces during the walkthrough. Really rare but amazing home! Homeowner was committed to clearing these spaces for better work conditions. The project involves extracting through the sump in the basement, connected to the son's bedroom and a utility room. The route goes from downstairs through the rim joists in the garage and out through the roof. A T connection will link the encapsulation points, ensuring a straightforward installation.
