"Exceeded our expectations! I called at 12:30 on a Saturday about a leak in our basement. He was there by 3:00. Found it was our toilet on the first floor. He fixed it all quickly and efficiently. Explained in detail what happened and why it happened. Even explained the hum we hear in the house when the water turns off. Even liked our dog Bruno!"

"Instead of listing all the things they did right I'll summarize by saying it was worth every penny! Water heater broke in the middle of the night. I called first thing in the morning. They brought a new water heater and had it fully installed by 6:00 p.m. WORTH EVERY PENNY!"

"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."
