I purchased a water softening and RO system from AFS. Andrew started the project the following week and finished it to my complete satisfaction. There were a couple of complexities to the install and he handled them expertly.

It was great. Our Condominiums were having problems with mice. We called Wilson Pest Management. Kody and his crew have worked hard at making sure the mice are gone and new ones do not come into the condos. Kody is professional and a pleasure to work with and his prices are very reasonable.

"Bill was wonderful and has our highest recommendations. He answered every call and replied to every message promptly, with knowledgeable responses. He was early to the inspection, took the time not only to inspect our new house thoroughly (no rushed feel), but also answered all of our questions as first-time home buyers in a very personable manner. He even inspected the roof despite the rain! Pricing was very reasonable and included all of the work we needed (added radon and pest). His thorough report came as promised later that day, and he answered follow-up questions we had afterward. We felt confident in our decision to move forward with our home purchase because of Bill's outstanding work. It shows that Bill really cares about his work and enjoys what he does. Excellent service, thank you!"
