"We had to have heat and ac added to our attached apartment. Derek came out and sized what we needed and they installed mini splits for us. Great work!"

"First off, the consult was great. I was able to add services to my initial request and received a deal doing so. I also added a second set of services later that month. Adam and Steve completed the work and were completely professional and super efficient. They answered my questions and made sure I understood the work being performed. They worked with my schedule and were fantastic. I had a gas hook-up for a change from electric stove to gas stove - they even took care of the permits and inspection. They removed an old water access point for the fridge's icemaker that was in an awkward spot. They also added a regulator for the water pressure and water filtration system. Fantastic work all around. Should we need any more plumbing/gas work, I would definitely hire them again."

He is very professional and a good personalty.He was a pleasure to have at my home and he is an asset to your company."

"They were very friendly and accommodating. Just really nice to deal with and their work looks and works great!"

"Technician was on time, made the repairs in short order at an excellent reasonable price."

"Chris gave me a very reasonable price to install the laundry in basement . The job was done quickly, inspection passed. I am very happy with his work. I will definitely hire him again!"

"These guys are great! The man who came to estimate the job had a medical emergency after leaving our home leaving the company very short handed. His partner not only got the information from our site visit but got our job scheduled within a week! He also pointed out some very ergent safety issues with our flexible gas line installed in 2000, but also saw an issue with our water heater put in by a subcontractor from Columbia Gas. Not only was the water heater not installed properly putting our safety at risk then we found out it was NEVER inspected by the city! They showed up on time and completed the job on time within their quote. They cleaned up after the job and were pleasent and curteous. I would highly recommend this company to anyone wanting a plumbing job to be done without being taken to the cleaners."
