A tidal-river town on the edge of Great Bay

Newfields is a small Rockingham County town wedged between Exeter to the south and Newmarket to the north, with the tidal Squamscott River forming its eastern line and the Piscassic draining the western half. Settled in 1638 and set apart as its own town in 1849, its compact village still holds colonial and nineteenth-century homes along Routes 85 and 108, while newer houses sit out on former farmland. Both rivers here run into the Great Bay estuary, so a home in Newfields lives with salt-influenced tidal water on one side, granite bedrock underneath, and a Seacoast winter overhead. Keeping one comfortable, dry, and safe starts with the season the town is built around.

Seacoast winters and the nor'easter test

Newfields does not sit far enough inland to skip a real New Hampshire winter, and the Seacoast catches the nor'easters that pile up heavy wet snow and drive cold through every gap in an aging system. Most homes here heat with oil or propane rather than natural gas, because there is no gas main running through town, which means an undersized or tired furnace or boiler is not just an efficiency problem. It is the thing standing between your family and a frozen-pipe night when the temperature drops into the single digits. We size heating to a real load calculation for the house instead of a rule of thumb, service oil and propane systems before the season rather than during the first hard freeze, and when a unit reaches the end of its run we replace it with equipment matched to a Seacoast winter.

Cold-climate heat pumps and the damp estuary summer

Modern cold-climate heat pumps hold their efficiency well below freezing, and New Hampshire's NHSaves rebates make them one of the better upgrades a Newfields home can make, especially a house still burning oil. Paired with backup heat for the hardest nor'easter nights, a heat pump heats, cools, and dehumidifies from a single system. That last part matters here, because summer air off Great Bay runs humid, and an oversized air conditioner cools the room fast and then shuts off before it pulls the moisture out, leaving the house cool and clammy and the basement musty. We size to the actual load, set the dehumidification up correctly, and for older village homes with no ductwork we add ductless mini-splits that deliver heat and cooling without opening plaster walls.

Granite-country wells: arsenic, iron, and hard water

Most homes in Newfields draw from a private well, and the granite bedrock under this part of Rockingham County is some of the most arsenic-prone in the country. Southeastern New Hampshire sits in a documented arsenic belt, and a well can test high while the water looks and tastes perfectly clean. That same granite pushes iron, manganese, and hardness into the water, which stains fixtures, scales the inside of your water heater, and shortens the life of everything the water touches. Arsenic you cannot see, smell, or taste, so guessing is not an option. We test the well for what is actually in it, then build the treatment the results call for, whether that is arsenic removal, a softener for the hardness, or iron and manganese filtration, so the water is safe to drink and your plumbing lasts the years it should.

Radon out of the same bedrock

New Hampshire has some of the highest radon levels in the country, and it comes up out of the same granite the wells draw from. Radon shows up two ways in a Newfields home: as a soil gas seeping through the basement slab, and dissolved in well water, where it releases into the air every time you run a shower or the washing machine. Both carry a lung-cancer risk, and both are invisible without a test. We test the water and the air, install aeration or carbon systems to strip radon out of well water, and set up sub-slab mitigation to vent the soil gas before it collects in the house. It is one of the few problems out here that is genuinely dangerous and completely fixable.

Old colonial homes and undersized panels

The colonial and nineteenth-century homes around the Newfields village were wired, if they were wired at all, long before central air, electric ranges, heat pumps, and car chargers existed. Many still run on undersized panels, fuse boxes, and knob-and-tube or cloth-wrapped wiring that was never meant to carry a modern home's load, which is both a safety problem and a hard ceiling on what you can add. We upgrade services to a safe 200-amp panel, replace outdated wiring with routing that protects old plaster, trim, and finishes, and add the circuits a modern home needs, including a properly installed EV charger and the dedicated circuit a heat pump draws, all done to code and inspected.

Power that stays on, and the well pump behind it

When a nor'easter takes the power out on the Seacoast, it stays out for hours and sometimes days, and out here that is more than a dark house. If your home runs on a private well, no power means no water at all, nothing to drink, flush, or wash with, and homes on the low ground near the Squamscott and the Piscassic fight a high water table and damp basements that need a sump pump running through the same storm that cut the grid. 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. We install generators sized for the real load and sump systems with battery or generator backup, so the basement stays dry when the power does not.

One call instead of five

The right-sized heating, the heat pump, the arsenic and radon treatment, the well and the sump, the panel upgrade, and the generator are one licensed, veteran-owned team, not five separate contractors to find, vet, and coordinate. Same-day service where we can, permits pulled and inspections handled, and a lifetime workmanship guarantee behind every bit of it.

Our own research, sourced and dated, on the problems that come up around here.

• PFAS: The Forever Chemicals In Your WaterNearly half of U.S. tap water contains PFAS, the federal deadline just moved to 2031, and four of the six regulated compounds are proposed for rescission. Here is what that actually means in New Hampshire, Maine and New Jersey - and what removes them.
• Chlorine Byproducts: When the Cure Creates the ProblemChlorination is one of the great public health achievements of the last century and I am not going to argue against it. But the chlorine reacts with organic matter in the water and makes something else - and your hot shower is a bigger exposure route than your drinking glass.
• Microplastics: What We Know and What We Do NotMicroplastics are in tap water, bottled water, food, air, and human blood and placental tissue. The WHO says current levels do not appear to pose a health risk. Both of those statements are true. Here is how to hold them at the same time.
• Pesticides in Your Drinking Water: The Atrazine ProblemAtrazine has been banned in the European Union since 2004. It is still one of the most heavily used herbicides in America and one of the most frequently detected pesticides in drinking water. The federal limit was set decades ago.
