"Dreadful experience. We had been customers of Astacio since 2015 when they installed our first tankless boiler which failed completely after 7 years and needed to be replaced in late 2022. ($10,000+) Their second one just stopped working; a dodgy board? The part is under warranty but they want almost $1,000 to replace it in the boiler; probably less than 2 hours work. I thought they used to be a good local business with ties to the community but be careful; their tankless boilers are unreliable and they'll try to rip you off when your heat goes out in the winter. So much for standing by their work. I'll never use them again."

Our team has over 90 years of combined experience providing reliable radon mitigation, water filtration, and well pump services and solutions to the Fairfield, New Haven, Hartford and Litchfield Counties of CT. Want to create a healthier and safer home environment? Call CT Radon and Well Water Solutions to schedule a no-cost radon mitigation or well water treatment estimate. We also offer cost effective well pump repairs throughout Fairfield, New Haven, Litchfield, and portions of Hartford and Middlesex counties. Schedule yours today!

"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!"

Wells and Pumps questions, answered by experts

The life span of a water pump ranges from five to 15 years on average. Regular maintenance can extend its life. If you notice significant drops in performance, strange noises, or frequent malfunctions, consider a water pump or well pump replacement. Always get in touch with a professional if you're concerned about yCan I install a water pump myself?our pump's condition.

A water well contractor or well pump repair pro near you is the go-to pro if your well water stops pumping. Well pump repair pros specialize in wells, reservoirs, and other water pumping equipment located outside your home. While plumbers are the experts in indoor waterworks and understand how wells pump water, they may not always have the experience with residential wells that well pump repair pros and water well contractors do.

Reduced water pressure, strange noises, or air sputtering from faucets.

Yes, most professional repairs include checking for leaks, sealing connections, and ensuring proper drainage.

A leaking well pipe is quite different from if the well itself is leaking. To seal a leaking well, pour a cement mixture or bentonite into the space between the well casing and the borehole wall. The heavier cement collects at the bottom to form a solid seal, pushing lighter materials like mud and fluids up toward the surface. Professional well installation companies have the equipment to do this properly.
