“Nate was very helpful and knowledgable. Had he been the one to come out to address issue the first time, it may not have dragged on this long.”

“We moved into our house 2 years ago, with the PEAK basement system already installed in our crawl space. Since we knew nothing about it, I called to transfer the warranty and ask some questions. From this beginning, everyone I spoke to at your company was extremely helpful and friendly.  I then called this summer to have an inspection done for our first time, since we were smelling a musty smell for the first time. Again, polite office staff and quick scheduling, as well as very willing to reschedule when I had a conflict. I’m not sure who I spoke to when a dehumidifier was suggested, but he was also informative, as well as apologetic when I had to call him when I didn’t hear back from him. That was appreciated! Cody was the one who did the inspection and felt we needed a dehumidifier. He also did the install. He is a polite and friendly young man! Because the system had already been installed, you were the ones we called. But I’m glad we did! These days it seems hard to find employees at a company (or self-employed contractors) who are responsive, friendly, and do what they say they will do, as well as act as though they appreciate our business. Thank you for being and doing all of these things!”

We have a small spot in our basement that is seeping water. Just noticed it today. Would like to have it inspected and repaired, and the rest of the space inspected, to insure there isn’t anything major. The home was built in 2001. Thank you!
