"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."

"We can't thank Mike and his team enough (Bobby and Alex)! We had an emergency flooding situation in our basement and Mike was able to come out to our home the day after I contacted him, despite not being scheduled for another week to install our drain system. They were incredible... extremely reasonable in price and worked fast and efficiently! Their customer service is exceptional! We highly recommend NH Dry Basement! You will not be disappointed! Thanks again Mike! Jeanne and John"

"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.

"We were very pleased with the communication and the outcome of our project. We have an old home with some older piping. Finding someone that works on steam boilers is tough. When they looked at the install, they explained what needed to happen clearly deand unrstandable."

"We hired Todd for an extensive remodel of our home and couldn’t be more thrilled with how nice it turned out, how smooth the process was, and how helpful Todd was along the entire way. The project has been complete for a while, I am just now following up with a long overdue review. Downstairs Todd removed 2 walls including a staircase to create an open living space for us. Where the walls were removed, he installed 3 new support beams per the engineer’s design, and then wrapped them with rustic oak boards to make them look like original beams, and they turned out beautifully. He installed all new trim around the downstairs windows to match the rest of the house. Todd gutted our old kitchen and built an island for us, installing all new cabinets, crown molding, and the appliances. He even custom modified 2 drawers in the island so that we could conceal the electrical outlets behind part of the drawer panel but not lose the entire storage space of the drawer. He did such a great job with the drawer modification they look like they came that way from the factory. The entire kitchen turned out perfect. During the same remodel, we also hired Todd to combine 2 bedrooms into a new master suite. This involved removing walls, installing a beam, and installing new walls for the new master bathroom and closet. While the ceiling was opened up Todd noticed a drip coming from above on a rainy day, and after finding the source, he offered us a very reasonable price to replace a small section of siding to ensure we wouldn’t have any water issues. We are grateful he was so observant and willing to go the extra mile for us by fixing this issue that was not originally in our scope. In the new master bathroom the extensive amount of tile and the new glass shower enclosure that he installed couldn’t have turned out any nicer, all the lines were perfect. He took great care in his tile usage, minimizing waste with his cuts which we appreciated especially on the expensive tile he installed in a decorative strip. Todd was great to work with throughout the entire project and very professional day in and day out. Being such a large project, as it progressed there were several things we realized we wanted to add to the workscope while everything was opened up. Todd was very accommodating and gave us reasonable prices for each addition we threw his way. We appreciated his flexibility very much. Todd also helped us with various design considerations, and had some great ideas that helped us work with the engineer to get the upstairs beams laid out in a way that optimized our new space. He pays close attention to detail and worked hard to ensure we would be happy with the end result of the project. Overall Todd is a real pleasure to work with and we highly recommend him and the quality of his work."

FAQs for sump pump or interior foundation drains installation projects in Dover, NH

Most residential pumps draw approximately 1,300 to 2,900 watts when they first start, then settle at roughly 800 to 1,050 watts during normal operation. The exact number depends on the motor’s horsepower and how often the float switch tells the pump to run. Even at the high end, the electricity cost is minor compared with the expense of cleaning up a flooded basement.

Grab a ruler and an empty 18‑inch‑wide pit. During a steady rain, time how much the water rises in one minute. Multiply that depth (in inches) by 60 to calculate gallons per hour, then add 50% for safety. If the result tops 2,100 gallons per hour—about 35 gallons a minute—you’ll need a 3/4‑horsepower unit. Anything lower, and a 1/3- or 1/2-horsepower pump should do the trick.

Loud rattling, constant cycling, or shuddering vibrations are the pump’s way of telling you it’s on its last legs. Musty smells, higher electric bills, and visible rust are other red flags. If the unit is 10 years old or older and exhibits any of these symptoms, replace it before the next heavy rain turns your basement into a wading pool.

You don’t have to hire a licensed plumber, but you should still bring in someone who installs sump pumps for a living—whether that’s a plumber, basement‑waterproofing specialist, or experienced handyman. They know the local codes, can wire the pump safely, and will test the system before they leave. Skipping professional help might void the warranty and could leave you with a pump that fails when you need it most.

Not every basement needs a pump, but if your home sits in a floodplain, has a high water table, or has ever taken on water during a storm, a sump pump is inexpensive insurance. For basements that only struggle with condensation or the occasional damp spot, sealing cracks and improving drainage may be all that is needed.
