Just wanted to say thanks again for having one of your professional technicians come out to the camp yesterday!

His thoroughness, knowledge, and professionalism gave me confidence that Gowland's was going to get this issue resolved and not rip me off in the process.

I used Gowland's to repair my heater last winter. He did an excellent job and charged a very fair price.
