"When our existing water tank started to falter we knew we needed to upgrade. Derry Plumbing and Heating installed a phenomenal tankless system for our 3800+ sq foot home and we never had a reason to complain. Our energy costs went down and we always had hot water for our family of 5 and numerous guests."

"George and his team were extremely friendly and professional. This is a good group of people. Courteous and thoughtful, they were able to do a complete installation of both systems from scratch in about 6 hours.
The new radon remediation system (Bubble Up) has the added benefit of boosting the fixture pressure in the house to city level or better (60-75psi) as well as completely resolving the pH level of the water.
The cost was slightly lower than the other two quotes we received, partially due to the fact that Absolute offered a "multi-system" discount since two systems were going in at the same time.
If in your service area, I would highly recommend George Doumit of Absolute Water System.

"Amazing. Todd was the fourth carpenter we interviewed, all from Angie's List, and we knew immediately he was the one. Unlike the others, you could tell that he was the kind of guy who does what he says; shows up; and does a quality job. He did all that and more and we couldn't have been happier with our choice. Todd did more than the projects he was given - he referred the electrician and plumber who also did a wonderful job and having the three of them know one another helped tremendously - as they would communicate scheduling amongst themselves. Todd was also the point person who was there when the granite was installed and found someone to cut and re-size our existing granite. Todd listens to what you want to do; asks all the right questions, provides very thoughtful ideas and solutions. He gets it. He is there when he says he will be; the quality of his work is excellent. He is a pleasure to have in your home; he cleans up as he works and is just a real nice guy. Todd is a skilled craftsman and we highly recommend him and will continue to have him to work as needed on our home."

"We took out the old tiles, removed the toilet and baseboards, and bought the tile before they came to do the installation. The work was done on 9-01-16. When I went to wash off the remaining haze a couple of days later, I discovered that the tiles were two different shades. It was obvious when they were on the floor. The person doing the installation should have seen this. We think he did but, since he didn't speak any English, might not have known how to communicate that to us. We called Pacific Stone & Tile and they said that they would come and replace the tiles that needed to be replaced. We could not match either shade of tile and had to buy two more boxes with a different shade number. Twice an appointment was made and canceled. The third one, 9-26-16, was kept and they redid the whole floor with the new tile. Before they started, all of the tiles were laid out on the garage floor to check for any variations. We had to buy the material to install the tiles, but they did not charge for any additional labor. The floor was checked before they left and everything looks fine. Tomorrow I will wash down the tiles to remove any haze and we can start thinking about getting everything back together again."

"Mitchell was very professional and great at the work he’s done on my 2 homes. I’ve had 2 bathroom remodels. Funace and hot water heater replaced. Put an expansion water tank on one of my homes. Hooked up my water for my new refrigerator and dishwasher. Have not had any issues with his work. Highly recommend."

I can't say enough about the owners, office staff, or employees who performed the work.

Always on time, polite, helpful, flexible and professional. They answer the phone when you call and return calls promptly when needed. The workers were in and out in 2 days and left the outside of the house clean of debris.

I cannot say enough good things about this company

"Called about leak Sunday morning. Plumber came out Monday, determined it needed replacement and notified Choice, who approved claim and permitted plumber to order new water heater. Thursday new water heater was installed. Was kept updated every day by both Choice and the plumber. Workers left my garage clean and I have hot water. Very satisfied and have recommended Choice Home Warranty on the Nextdoor app."

FAQs for water main install, replace or repair projects in Portsmouth, NH

If you notice puddles or standing water in your yard, a sudden drop in water pressure, cracks forming in your foundation, frequent clogs in your plumbing fixtures, or water that looks or smells unusual, you might have a leak in your main water line. These signs mean it's time to call a professional to evaluate the issue and prevent further damage.

A professional water main inspection is a comprehensive evaluation performed by a licensed plumber who checks every section of your plumbing system. The inspection costs $165 and uses advanced diagnostic techniques to identify hidden leaks or wear. This service clarifies the exact condition of your water main, enabling precise repairs that prevent future damage and ensure the overall health of your plumbing system.

Protect your water main by scheduling a cleaning and inspection every two to five years. The average cost of a sewer line cleaning is $400. It’s also important to never dig in your yard without first calling the dig line (811) to ensure you don't accidentally hit the water or sewer lines. Watch for soil erosion, low water pressure, or wet spots in your yard, and take immediate action if you suspect a leak. Remember, the longer you leave it, the worse the problem gets and the more costly it is to fix.

When properly maintained, your water main is engineered to remain functional for 50 years or longer. A durable water service in excellent condition should consistently perform without major issues for half a century. In contrast, metal pipes exposed to acidic soil corrode faster, whereas modern plastic pipes resist corrosion and function for decades beyond metal alternatives. Regular maintenance and inspections are essential for confirming your system’s longevity.

No, homeowners insurance does not cover the cost to repair a water main. Insurers fund only sudden, unforeseen events like a burst pipe and exclude gradual issues or normal wear and tear. Damage resulting from leaks, such as mold remediation or property claims, is not covered. It is essential to contact your insurance provider immediately to confirm your policy’s details and any potential adjustments needed.
