My spouse and I are in the inspection phase of buying our first house. We had Brian and Adriel out to give us a roof inspection and they were incredibly honest, answered any and all of our questions and wrote us up an awesome report that we could send to the seller. If we end up settling on a price, we will definitely be in touch with GKontos! Excellent customer service
