Getting to Know Hallowell
Hallowell's first European settler, Deacon Pease Clark, arrived from Massachusetts in 1762, and the city takes its name from Benjamin Hallowell, a Boston merchant and one of the Kennebec Proprietors who backed its early development. Between 1783 and 1901, the city launched roughly 50 ships from its Kennebec wharves, part of an economy that also leaned on granite quarrying and ice exports.
In 1875, Hallowell became home to the Maine Industrial School for Girls, the state's first reform school for girls, which stayed open into the 1970s. Downtown still shows off its 19th-century commercial architecture, anchoring a historic district that gives Hallowell one of the best-preserved old riverfronts on the Kennebec.
Hallowell Homes and What They Need
Hallowell's median home was built in 1938, with 57 percent of the city's housing dating before 1940 and 64 percent before 1960 -- the oldest stock of any of the four Kennebec towns Aces serves. Much of downtown and the residential blocks around it fall inside the Hallowell Historic District, listed on the National Register since 1970 and covering roughly 450 buildings, about half of them built before 1865. A rewiring job in that district usually means working carefully around original plaster and trim while still bringing the electrical up to code.
Heating and Cooling in Hallowell
About 42 percent of Hallowell households heat mainly with fuel oil, 17 percent with utility gas from Summit Natural Gas of Maine, and 14 percent with electricity, per Census estimates -- a more mixed fuel picture than some of its Kennebec neighbors. That mix means we are regularly quoting side-by-side comparisons between keeping an oil boiler running and switching part of the load to a heat pump.
Water Supply and Drains in Hallowell
The Hallowell Water District supplies the city's water from gravel-packed wells located in neighboring Chelsea, not from wells within Hallowell itself, while sewer service runs through the Greater Augusta Utility District's plant in Augusta. Hallowell sits right on the Kennebec River, which has a documented history of spring flooding that has disrupted downtown businesses more than once. Homes closer to the river benefit from a sump and drainage check as part of any plumbing inspection.
Power, Storms and Wiring in Hallowell
Central Maine Power serves Hallowell, and given how much of the city's housing predates 1940, older service panels and undersized circuits are a common find, especially in the historic district's converted 19th-century buildings. A panel upgrade is frequently the starting point before a Hallowell homeowner can add a heat pump, EV charger or modern kitchen circuit.
Local & Independent — Not a Franchise
Aces Highlands is a locally owned Portland, Maine company serving Hallowell — not a national franchise. Our technicians are not commissioned salespeople and nobody here is required to upsell you anything. We do the work you called us for, do it right, and earn the next call. That is the whole business model.
