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!"

"After Garrity refused to repair the (very) expensive damage they negligently caused to the heating element in the water pipe providing water to my home, I had to sue. Don?t trust them. Don?t hire them. Don?t go near them. If you think they are the gold standard, as I did, just ask other professionals in the same business. Beware, stay away from them."
