We recently had Frontier Plumbing come to our home to fix a shower valve. Mitch came to our house on time and was very professional and clean. He diagnosed the problem and said we needed a new part. So, he took the old valve out and put a new one in. The office had asked me to take a photo of the shower valve when scheduling the work so they had the part ready. What an organized and dependable company. We will be using them again.
