"Ralph was excellent. He called within minutes of me submitting the Angies List request....... and came the very next day to fix our problem. He was pleasant, down to earth, honest and did the repair quickly, solidly, and for the money he’d estimated. Overall we were very very happy with our choice to go with Ralph!!"

"Ralph was awesome!!! Friendly, knowledgable and heartfelt. My well pump stopped working 11:30 PM on a Saturday Night, Ralph replaced my well pump on Sunday. The the same day I posted the request. My well pump and pressure tank was twenty years old. I learned a lot too! He answered all my questions from my YouTube research. He walked me through the process and let me know what was going on. Most of all, the pricing was reasonable and I am happy with the work."

"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!"
