"I had a tankless water heater installed. I gave 4-1/2 stars for overall rating because the worker who came was the lone installer and had no one to help. I could not use water for almost sever hours an inconvenience since job was estimated to be "about 4 hours". I think he took a deserved lunch break for about an hour. He was on time and was courteous and pleasant. Would have been nice if he had a helper."

"Talked to Scott I explained what needed to be done. Sent a couple pictures of the problem and he gave me a price. We are very pleased with the outcome off the work. The workers were on time and did a professional job installing and piping the spigots. There was no mess when they left. They were the cheapest of the 4 plumbers I talked too. Some didn't even call me back. They even left a gift which is super helpful and appreciated!!! Thanks for a job well done."

"It couldn’t have gone better! Carl was experienced, knowledgeable and friendly. Plus, he smelled gas which is why he replaced the valve on my water heater. It was a great visit!"

"Patrick was very responsive to my texts relates to product information and quotes. He is very knowledgeable about the trade and he is great with customers. His service was prompt and the installation went smoothly. After the installation, I referred another friend to Patrick on water heater replacement."
