HVAC, Plumbing & Electrical in Madbury, NH

A small rural town between Dover and Durham

Madbury sits in Strafford County, tucked into the Seacoast region between Dover and Durham with the University of New Hampshire just to the south. It is one of the smaller towns in the state, roughly 1,900 people spread across twelve square miles of woods, old farm fields, and wetland, with Hicks Hill topping out around 331 feet and the Bellamy River and its reservoir running through the middle of it. The housing runs the full range here, from garrison-era and colonial farmhouses that predate the town's 1775 incorporation to postwar ranches and newer builds out along Routes 9, 108, and 155. Almost none of it is on town water. Keeping a home comfortable and safe in Madbury means working with the well underneath it, the cold that comes off the coast, and the storms that roll in behind that cold, and it starts with the winter.

Seacoast winters test the heating

Madbury sits about ten miles inland from the Atlantic, close enough that Nor'easters and coastal storms hit hard and often. Winter here is long and genuinely cold, and a January cold snap or a multi-day storm finds every weak point in an undersized or aging furnace or boiler, usually on the worst night, when a heating failure is not an inconvenience but a frozen-pipe emergency in a house set back off a rural road. We size heating to a real load calculation for the house rather than a rule of thumb, service furnaces and boilers before the season instead of during the first hard freeze, and when a system reaches the end of its life we replace it with equipment matched to a real Seacoast winter. Heat that holds through the coldest stretch is the whole point of the system.

Cold-climate heat pumps and humid Seacoast summers

Modern cold-climate heat pumps now hold their efficiency well below freezing, which makes them a real option even this far north, and paired with backup heat for the hardest cold snaps they heat, cool, and dehumidify a home from one system. Summer on the Seacoast is humid, and humidity is where sizing matters most. An oversized air conditioner cools the air fast but shuts off before it pulls the moisture out, leaving the house cool and clammy and, in a wooded town with a lot of low ground, prone to musty basements and mold. We size to the actual load, set the dehumidification up properly, and for older farmhouses that never had ductwork we add ductless mini-splits that deliver comfort without tearing plaster apart.

Private wells off New Hampshire bedrock

Because Madbury has no town-wide public water, nearly every home draws from a private well and runs its own septic system. That water comes up through New Hampshire's granite and metamorphic bedrock, and southeastern NH is one of the worst areas in the country for naturally occurring arsenic in drilled wells, along with uranium and radon dissolved out of that same rock. On top of that the water often carries iron and manganese that stain fixtures and laundry, and hardness that scales the inside of your water heater and shortens its life. None of this shows up in the taste or the look of the water, which is exactly why it gets missed. We test the well for what is actually in it rather than guessing, then build the treatment the results call for, whether that is arsenic removal, a softener, iron and manganese filtration, or UV, so the water is safe to drink and your plumbing lasts the years it should.

High water table, wetlands, and a wet basement

A lot of Madbury sits on low, wet ground. Wetlands line the Bellamy River and the branches of the Oyster River that rise on the west side of town, and the glacial soils here hold water long after a storm. Homes on that low ground fight a high water table and spring snowmelt pressing groundwater against the foundation, and a basement that stays dry in August can take on water every March. A sump pump is the front line, and a sump with no backup fails on its one big test, because the water peaks during the same Nor'easter or ice storm that knocks the power out. We install sump systems sized for real volume, add battery or generator backup so they keep running when the grid does not, and address the grading and drainage that let water reach the foundation in the first place.

Older homes, older panels, and modern loads

Madbury's farmhouses and mid-century homes were built long before central air, electric ranges, heat pumps, and car chargers existed. Those houses often still run on undersized panels and old wiring that were never meant to carry a modern home's load, and that is both a safety issue and a hard ceiling on what you can add. We upgrade services to a safe 200-amp panel, replace outdated and worn wiring with routing that protects plaster, trim, and finishes, and add the circuits a modern home needs, including a properly installed EV charger and the dedicated circuits a heat pump or well treatment system requires, all done to code and inspected.

Power that stays on through an ice storm

Madbury's rural, tree-lined roads and long overhead lines mean the power goes out here, and Seacoast ice storms and Nor'easters take it out for hours and sometimes days, not minutes. A whole-home standby generator keeps the heat, the well pump, and the sump running through a multi-day outage, starting on its own when the utility drops and shutting down when it returns. On a well-and-septic home that matters twice over, because when the power is out you have no water at all until the pump runs again, and the basement is filling at the same time. A generator is what keeps the house livable and dry through the exact storm that cut your power.
