We Know
Plaistow Homes.
Plaistow is a small town right on the Massachusetts line. Most of the shops and businesses line Route 125, and the neighborhoods spread out behind them.
Housing: Single-family houses make up about three-quarters of Plaistow's housing stock. Nearly a quarter sit in multi-family buildings. Most went up in the 1970s and 1980s, with the 1980s the busiest stretch. You'll see plenty of ranches and capes from those years mixed in with older houses and some newer builds.
Furnaces, Boilers &
Heat Pumps
Heating in Plaistow
Oil is the main fuel across Plaistow, and a lot of it heats the town's ranches and capes. Natural gas runs along the built-up Route 125 corridor through Unitil, but oil is still the most common fuel townwide. A big part of our work here is swapping out old oil boilers and furnaces. We move homes off oil to a heat pump to cut fuel costs, and we switch others over to natural gas where a natural gas main runs along the street. A house without natural gas service may continue with oil or propane or switch to a heat pump.

Air Conditioning &
Mini Split Installation
Cooling in Plaistow
Many older oil-heated ranches and capes lack ductwork. With no ducts in place, a ductless mini split is a good way to add cooling without tearing into finished walls. A mini split also provides heating during spring and fall. That combination of cooling and supplemental heat is one reason homeowners consider reducing their oil use. If a house already has a forced-air furnace, central A/C is the better fit. We size either option to the home.

We install and service central air conditioning, heat pumps, and ductless mini splits in Plaistow. We have installed thousands of ductless systems across Southern NH. Whether you need a summer repair or a complete replacement, we respond quickly.

Water Treatment in Plaistow
Plaistow has both municipal water and private wells. Plaistow's municipal supply comes through Hampstead Area Water Company's Core Water System, which blends groundwater from its bedrock wells with water from the Southern New Hampshire Regional Water Connection. That connection was developed in part because of limited local supply and past concerns about methyl tert-butyl ether (MTBE), a gasoline additive, in some areas.
MTBE is not present at every address. Detections of PFAS (per- and polyfluoroalkyl substances), a family of long-lasting chemicals, have also been documented in some private wells within a limited area near the municipal mains. For a private well, laboratory results determine the need for sediment, iron, manganese, hardness, bacteria, or contaminant-specific treatment.
PFAS and MTBE results require equipment with verified performance for the substance measured. Company-water customers may choose whole-house carbon or an under-sink carbon or reverse osmosis system for a defined household goal.
Water Treatment Services We Provide
Plaistow homeowners can call us for water-treatment installation and service. For a private well, an independent laboratory analyzes the sample before we select and size the treatment equipment.

Plumbing in Plaistow
Plaistow homes may receive Hampstead Area Water Company service or use a private well, so treatment and pressure can vary from one address to another. That information helps with whole-house concerns, while most plumbing work remains inside the property. We repair faucets, toilets, valves, leaking supply lines, water heaters, and household drains.
If a tested water condition or existing filter is contributing to restricted flow or premature wear, we can address that connection as part of the service.
