Second opinion on mitigation approach
Hello! I’m going back and forth with a radon mitigation company and our landlord right now about the installation of our system, and wanted to get a second opinion on their proposed approach.
We live in a 3-story townhome, and while I originally hoped we could run the pipe up to the roofline, it seems like there isn’t a good way to do so, and so the company has proposed a different route, through our mud room and garage, to ultimately vent out horizontally over the top of the garage. They initially wanted to put the vent maybe 5-6 feet horizontally and vertically level with our bedroom window (see photos, including our mirroring unit where they took the same approach), until I got a supervisor to agree that that wasn’t safe.
I’ve attached pictures of our layout. The current plan is to run the pipe from the crawl space, up through the mudroom floor, outside to the back patio of the unit where the fan would be, and then back into the garage, up through the roof of the garage, and then out at least 10 feet from our bedroom window.
I included pictures of what I originally assumed would happen, but they said they weren’t able to do this because the pipe can’t block windows even by a tiny bit, and because that much pipe/that many bends would be too hard on the system. Also, we have a rooftop patio, so the vent would have to be far enough around the corner to not be an issue for the patio or the operable bathroom window.
I’m hoping some who are more knowledgeable than me can advise on whether the company’s proposed approach is the best option, if I’m overlooking anything, and if this is a safe distance from our living space to where we could have complete peace of mind that radon isn’t re-entering the property.
Thanks so much in advance for your help!
