"Discovered no water pressure late one evening and leaving for vacation next day. Called R&G at 11:30 pm and Rick walked us through the possible issues. He was at our house the next morning and found the problem quickly and at a minimal cost. He absolutely saved our Spring vacation as we could not have left with no water at the house. Very knowledgeable about water pumps, provided a quote to replace ours at it is reaching the end of it's life and I won't consider using anyone else!"

"They were up front with what is wrong. Provided explanation of the quote. Asked permission to get access to places. They explain the reasoning for the cost and the risks if ignored. Pricing was fair. Went above an beyond to solve the water heater issue we had. Even calling in an electrician to help with a fix. They were on-time to early on their scheduled appointments. Excellent customer service."
