"Randy Williams was both very professional, very knowledgeable and just a genuinely nice guy. The install of the water filtration system was my first for my first home and he put my nerves at ease. If you have a question about what he is doing or about what equipment is being installed he will answer it. He went over everything he installed with me and made sure I understood what I needed to do on my part to maintain the filtration system. I highly recommend his company for any install or service you may need for your water."

"DB's has emergency service so, when the water line to my refrigerator was leaking late at night, they came out right away and replaced the line as well as the decrepit faucet that feeds it in the wall. The water line replacement moved pipes to a route under the house with no disruption to the walls. A small area about 18 inches square in the floor of the basement utility room was re-cemented, so there is no evidence of the replacement and they re-seeded the area in the front lawn that had to be dug up. This company has never failed me. They stand behind their estimates and never charge more. I highly recommend them."

"Incredible. I had installed a water filter system 8 years ago that provided adequate filtration enough to prevent toilet fill valve restriction. I had a water treatment company (no good)replace my filters because of the maintenance headache. They installed their filter treatment system and after two days my water looked like shit, literally. My toilet fill valves began to clog after about a week. After a couple of weeks with no resolving the problem it was time for a change. I contacted Waterboy and met with Roy and Rita. We agreed to make the change. That was on a Wednesday and on Friday they were there on time to remove my worthless system and install theirs. The installers were professional, knowledgeable and did a great job. They flushed and sanitized my water lines after installing their filter treatment system. I can't believe that after a couple of flushes of my toilets they are now filling like they were prior to that previous, worthless, filtration system was installed. They truly know water treatment."

"As part of our service plan, we had our plumbing systems inspected. To make sure we were safe in the future, I had the technician drain the water heater and install an alarm in case of flooding or system failure. Everything went well and I highly recommend FH Furr."

"We canâ t thank Terry Butcher and the technicians (Dwayne and Dakota) enough for installing our complete water treatment system, including a new water heater, for our main home AND at our airbnb, reinstalling the well pump and pressure tank system (to correct previous install that kept failing), installing a complete water treatment system, water heater, including replacing wiring, and encasing it in conduit, and burying it underground as it should have been in the first place. Dwayne has incredible knowledge and expertise and is a great mentor for Dakota who is a fast learner and who takes pride in his work. Terry Butcher was at the tap of his number and responded quickly and effectively to our needs, with patience and courtesy! . We feel positively comfortable in recommending this team to homeowners/builders. Sincerely, Bob and MaryAnn Butterfield"

"Jamie our plumber arrived right on time & very efficiently performed three jobs for us. These included replacing a kitchen disposal, installing a vanity water faucet, flushing the water heater. He patiently explained each task and stayed until all were completed. We were so pleased we've entered into a service contract with Beacon Home Services."

"Matt, Paul and Jonathan arrived on time ready to work. They explained what they were going to do and started by insuring our house would be protected from removal of the old system. Everything that Fred Ouellette explained during the estimate visit a month earlier was right on. after the installation they took the time to explain the new thermostat until we were comfortable with operating it. After they left, I took one more look around the house and noticed they forgot to put putty around the opening of the house were the pipes and wire entered. i thought no big deal i'll just get some and do it myself, about an hour later, Matt rang the doorbell and said he saw the putty in the truck when he got back to the office and on his way home from a long days work stopped by to finish the job. Honest hard working people."
