"I would not recommend. I am a real estate agent and contracted this company to install a radon mitigation system in a home prior to closing based on a high radon level test during inspection. I met the company rep at the property and he quoted a system later that day after inspecting the home. The system was installed two weeks later and a retest came back more than double the level of the initial test. This company claims they have a warranty to cover any system modification to get the levels below 2.0. The company sent a crew back out twice and yesterday said the slab is too thick for the system they installed, the hole the installers drilled is too narrow and the home is in a flood zone. We knew the home was in a flood zone, but this company never asked about that and did not do any due diligence prior to installation. They are refusing to honor their warranty and are now quoting a different system that is much more costly. Can?t recommend."

"Three years later we're still dealing with the fallout from Garrity's shoddy work. We hired them to install a pump and sensor system to supply water from a new dug well. They consistently cut corners and over-charged us. We have had to hire another company to fix the issues they created (for instance, the pump controller shorted for the second time last week, and each replacement has cost > $1,500)."

"For weeks, we were getting less and less water from our faucets. Finally, we were down to a dispiriting trickle. A first visit from Garrity did not resolve the issue. When, concerned, I called back several days later, they immediately dispatched Joe and Cody, who arrived w/n 15 min. They probed deeply to find out the cause, discovering a cracked pipe and failing well pump, dating from about 30 years ago. They installed a new pump and new well cap up to current code and ensured that the water coming from the well was bacteria-free. This am, Joe was back by 8 am to show us how to flush all chlorine residues from our system and explain what he had done. Joe was determined, undaunted and kept at it until he found the cause of the inadequate water pressure--despite the late evening hour yesterday. His explanations were informative, clear every step of the way and helped us understand what was going on. He was patient, amiable and very good at what he does. Thank you Joe, Cody and Garrity!"

"Ralph was our first call once we submitted what we needed. He was professional, happy to answer any questions and head right over to take a look for himself. He sent me a quote for review, and after getting similar prices from other providers we decided on HV Water because Ralph made my husband and I comfortable and as if he was doing this on his own house. The install day was spotless, both installers were professional, meticulous and thorough. Cannot recommend these guys enough. Thanks again for an amazing job."
