"The job was done very well. Our lower level was a major problem and it turned out that our fuse box was in serious trouble. The team explained the problem and quickly fixed the lower level issues and fuse box. The bathroom fan needed parts in order for the installation to be completed to my satisfaction, the technician showed me exactly what to order and I have, he is coming back out to install them. We are pleased with the work, how easily it is to make an appointment and they were on time, in addition I received an email with the a photo of the technician and name therefore I knew ahead who was coming to my house."

"Chris and his assistant did an excellent job of explaining the situation and options for repairing or replacing our hot water heater. In the end we chose to replace it and they were able to secure a new unit and install it within 3 hours. Would definitely recommend Chris and Tri-County Services and will use them again if another situation arises."

"On Thursday, the technician (David) came to my house to look at two projects: replacing a leaking electric water heater, and installing a new gas line (in my crawlspace) to my masonry fireplace so I can convert from wood to gas logs. He explained my options, and quoted prices for these options. I asked if he could do the work on the upcoming Saturday, and he scheduled this before he left! I ordered the gas tankless water heater and the gas line to my fireplace. By the way, I had 3 different plumbers look at this work, WyattWorks had the lowest prices. On Saturday David and Alex arrived early in the morning and worked past 6:30 PM to complete both jobs. The installations were great. Everything to code, and with neat, high quality workmanship and thoroughly tested. They cleaned up the work areas and hauled away my old water heater. In other words, a typical WyattWorks job."

"Thank you for sending Brandon Seiber to me today! He was fantastic. I called Mr. Electric at 12 Noon to replace breakers on an old fuze box and he not only showed up within an hour of my call, but watching him work he flew through it making it look so easy. Afterwards he asked if there was anything else I needed. We inspected my outlets which were so old that wires dangled half-way out of them. He gave me an exceptionally fair price to install new ones. Very knowledgeable he explained everything he was doing as he went. and his work was as good as it was fast. I will be recommending your company and Brandon to all my friends and neighbors. The reason I never updated my outlets was because I was afraid of the cost and your prices were good enough to entice me."
