"From calling for info to getting booked, everything was clearly explained and we felt very prepared for the appointment. We were able to get booked just a few days after we called. Quoted price was about $1100, and we were happy to move forward with their quote versus others we called. Install was great. Nick arrived and got right to work, listened to concerns about placement, and walked me through everything as he was planning to go. Measured thrice, cut once! From beginning to end, with a few snags in the process due to stucco exterior and numerous utilities packed into the space he was working, he was done in just over 3 hours. Impressive work, and very professional. Guarantee to get numbers for radon below 4.0, and 5 year warranty for the fan. Ended up having to upgrade to a bigger fan due to the hard ground under the slab, and that made the price go up a bit, but still within our budget. Only complaint is that we weren't made aware that this was a possibility going into the appointment, but can't say we didn't want the upgrade--without it our system wouldn't have be adequate to mitigate. Happy so far with everything, and looking forward to the free test kit in a week to see how much better we are in readings. Finished basement means we'll be down there a lot, so we were very happy with how everything went so far, and look forward to living in a safer house thanks to SWAT!"
