"This was a complex retrofit tankless water heater installation and out of 30+ companies called and solicited for this project, Brett and Dunn's HVAC was the only company to 1) entertain performing the installation correctly (gas line sizing and calculations), 2) had prior experiencing working with tankless heaters, and 3) took the time to work with me on a long list of specifications. These are bulletproof systems if the installation is done correctly and Dunn/Brett took the time to ensure the install was on point and everything went smoothly. They also installed a softener and filtration system. Everything went well from bid to install and I highly recommend Brett and Dunn's - will use again as I could not be more pleased!"

"I would highly recommend Anytime Plumbing! The customer service by Steve was excellent! Friendly, Professional and very responsive. We needed a water heater replaced on a Friday and he was at my house the same day within an hour! He also completed with Rebate form for the water heater with an envelope and stamp too! The pricing was affordable and less than competitors in the area! I will definitely call Anytime Plumbing in the future and recommend to my family and friends!"

"DP Plumbing and his crew went above and beyond to make sure that this job was done correctly and for the most reasonable price possible. They were professional efficient and got the job done as quickly as possible. I would highly recommend this company to my friends and family and to anyone else who wants a fair price and a professional team working at your home. I had other people come out and give me bids and none of them gave me the Comfort level that this company did. I just trusted them. I am actually having some other work done and have their card because I'm going to give them a call back for sure."

"We hired Master Remodel & Construction after our master bathroom, kitchen and garage suffered major water damage after an interior flood caused by an overflowing toilet. Brian Inkley (owner) and Jacob Quick (project manager) have a team of dedicated, talented professionals. They did a superb job in restoring our damaged house. They are a busy team of workers who kept us appraised of their availability for the various stages of our restoration. For the repairs that they didn't do themselves they had excellent recommendations for the professionals we needed such as the carpet installation, closet system installation, kitchen cabinets and the refinishing of our hardwood floors. They seem to be in demand, working at several projects at the same time but we always felt that we were their top priority. Jacob worked with our homeowners insurance adjuster to be sure that the funds allocated for our losses were enough to complete our projects. We recommend Master Remodel & Construction with pleasure."
