"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)."

Customer service and honesty are the most important aspects of our business, and your satisfaction is guaranteed. Please call us today for an estimate. We look forward to working with you.
"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!"
