Good so far! System is running fine. Pretty seamless install. They were very helpful and communicative about changes, okayed first, cleaned up well, and answered all my questions.

Everything was great! The crew treated us well, were very friendly, and there was little to no destruction.
By James
Our levels dropped 60% in 14 hours! We are now at a 3.1 pCi/L down from 8 pCi/L — much more than I thought it would be. Did a good job, professional, couldn't ask for better guys.

    This is a single point system in the basement that is fairly open and going out the back side of the home. It will need to go out through the rim joist on whatever looks best on the backside of the home. Carey - the Project Specialist was not able to get a photo of the back to two in the appointment was so it will be up to the client's judgment where it looks best. The team can make it work with her preference anyway due to the allowance in the room where the radon mitigation system will be set. There's no sump it downstairs so we can place it wherever for an extraction point. It was an easy install as the client was cooperative!

    The client is a physical therapist and likes the outdoors. He has an unfinished basement with two different crawlspaces. He has access to one through a window in the basement and the other has an opening into the second crawlspace. They're about 3 feet in height and the walls have spray foam insulation on them. It was not much of a challenge but there was some work done for the first extraction point to begin with. The client was really kind in helping clear out the debris in the crawlspaces after installation. He was really happy with how the system turned out.

    This is a single point system that will be going out in the corner of the house facing the neighbor. There are also some cracks in the basement in which the homeowner said that he would be filling in. There is a fairly large crack over towards that exterior basement door at troubles into the little music room that they created. Guarantee rate on levels. His contract shows and he agreed with me that he understood that this was okay and understood that it was a place right now and could come into His home. There are three open holes for plumbing that are Old Clay tiles that need to be sealed up. One looks like a toilet might have gone on it the second one is a open hole and third one is under the carpet and the little band area. Homeowner agreed that the team will be sealing it up with plexiglass. Everything went well as expected!

    This client was a close friend of our techs but no special treatment here! We did check their levels first and advised the ideal system for their home. Nathan's parents would be moving with him soon. He wants to make sure his home is overall protected from radon exposure. This home has an interior system that was going to exit through the peak of the roof in the garage. Utility room is only sharing a wall with the garage but they have a metal roof. We were really careful as we still don't want to destroy the aesthetic of the home. This needed to be a 2-point system to begin with as the team was informed that their levels returned around 20s. Pretty high.  Originally designed 1 point prior to hearing that and adjustments have already been made.

    This was a simple installation as the homeowner's wife was really concerned about the high radon exposure during the winter season. She called up Iowa Radon Defense and asked for a quote. They were happy with the pricing and discussed the drafted plan with them. Everything was virtual as they knew their home very well and provided all the photos needed for the team to reference to. They will be on vacation during Thanksgiving, so they wanted this to be done before that starts. The wife was happy about the team cleaning up before leaving as she thought she would be doing it. Everything went well!

    Homeowner just moved in the home last month and needed help with the old mitigation system. There were fairly large cracks into the foundation which need to be sealed. It was a huge home and we did discuss his options for replacement as it would be a more practical choice. He agreed and went on decided to have the fan placed outside of the home this time. Homeowner also asked about duct cleaning as a I just moved into the house within the last few months and told me that air flow seem to be an issue. There is a room that is painted blue in the back of the house apparently has no air float to it.

    This project is a single-point system at Moby going out of the back side of the house. The HVAC system some pit are located in the center wall of the basement. Homeowner currently works downstairs and has a family which is the reason why they're looking to have a system there -- for extra protection. The sump pit is needed to be covered by a piece of plexiglass as I believe it is too small with where it is located to put an actual cover on. The homeowner did have interest in her filter budget was a concerned so could be worth a follow-up after the installation. He was a really straightforward but nice to talk to!

    This installation was referred by one of satisfied clients, they needed help as their home does not have much space to place a system but they know we can work something out. We didn't disappoint once we saw the client's 3-chamber home. The client's crawlspace was decent enough to work with and did not give us a difficult time on how it should be placed. They even requested crawlspace encapsulation on the spot. Everything went well!

    The client, with a background in HVAC, discussed plans for his home, originally lifted and dropped back on a foundation, causing a spike in radon levels. With the downstairs undergoing renovation, he aims to hide the radon system in the ceiling near the joist, dropping it down about a foot and a half. Three extraction points are planned: one from the sump area, extending to a storage area, and the third running towards the staircase, exiting near the sliding door. The client will handle drywalling a portion himself, prioritizing a concealed installation. He'll be present during the installation for any adjustments or complications. Given initial levels of 20 and occasional deviations, a cautious approach involves implementing a 3-point system.

    This was more complex than we thought it would be as we are looking to extract out of the utility room. Homeowner is finishing home and will like to run the PVC line along the listing ductwork and out through the rim joist and virtually how the PVC in the Sill plate. The team took some pictures and mark them up and read to indicate where he was thinking about running the pvc. He told me that he would have that existing pools cord and I told him that there was a slope that was needed and he said he would take that into account. The homeowner is a very DIY individual and has done a lot of good work on his home. He is going to core through his roof is sealed that up himself as he has done work on barns in the past and told us that it would be fine to just run the PVC up through and he would take it from there. This is because he has a metal roof. The third part of this is that the sump is in a finished area in the basement he will be lining it and throwing carpet over the top so we will need to seal up the sump with plexiglass instead of a dome lid so that he can finish over it. He is also left the discharge in the wall open to see if we needed to do anything with this. Homeowner said he would be available and present during the install, he's a super nice guy but wants to make sure that we're running it where we need to that way he can hide it and frame it out. He got the outcome he wanted.
