We Know
Suncook Homes.
Suncook is a mill village on the Suncook River, split between the towns of Pembroke and Allenstown. The mill-town past still shows in the brick factory buildings and the storefronts that line the river.
Housing: The homes in Suncook run old. About 42% of the village's housing units date to before 1940, and the median build year is around 1951. The older neighborhoods have capes, ranches, and mill-era houses on small village lots. A lot of the stock is multi-family too: two- and three-family homes, plus old mills turned into apartments and condos. About six in ten homes are owner-occupied.
Heating: Liberty Utilities runs natural gas mains down the streets of the tight village core, and a lot of Suncook homes heat with it. Past the core, where those mains stop, houses run on oil or propane instead. The homes are old, so plenty of aging boilers are still running, some decades past their prime. Others have hot-water and steam systems that have been patched over the years. We do a lot of boiler replacements out here. We also handle oil-to-natural-gas conversions when there's a main on the street, plus radiator and near-boiler piping repairs.
Cooling: Most of these older homes run on boilers, not forced air. There's no ductwork for central air, and adding it means opening up walls. That's why ductless mini splits are such a good fit here. They go in without tearing the house apart. They cool in summer and add efficient heat in the shoulder seasons, and they work well in the two- and three-family homes and tight village lots where running new ducts just isn't practical. If a home already has ductwork, we install and service regular central air too.

Trusted Since 1928.
The mill-era and older homes around Suncook tend to have tight, low basements and cramped mechanical rooms. Their systems have been touched by a dozen different hands. They carry the aging plumbing and wiring you'd expect in a century-old house. The converted mills and multi-family homes bring another wrinkle: tighter access and shared systems. We take the time to figure out what's really going on before we recommend anything, and because we run crews in all four trades, we can handle whatever the old house throws at us.
