Insulation, Mold Removal and Basement Waterproofing for Bangor Homes

Lumber-era houses and three-deckers

The Greek Revival and Victorian homes in the Broadway and Whitney Park historic districts, and the blocks rebuilt after the Great Fire of 1911, were framed long before anyone filled a wall cavity. Census estimates show about one in five Bangor homes is in a building of three or four units, and fewer than half are owner-occupied, so a lot of heat escapes through shared attics, balloon-framed walls and old stairwells. Dense-pack cellulose suits those closed walls, and sealing the attic floor and rim joists stops the draft that pulls warm air up and out.

River city, stream valley, spring water

Bangor sits where Kenduskeag Stream drops about 100 feet in two miles to meet the Penobscot. The city's recorded floods have mostly come in spring from snowmelt and ice jams, with bad years in 1846 and 1902, and in 1976 a storm surge pushed the river up roughly 12 feet in 15 minutes downtown. Most basements never see river water, but groundwater rises every April against fieldstone and brick walls. Interior perimeter drainage with a sump pump is the usual answer for a cellar that seeps.

A long heating bill

NOAA's 1991–2020 normals for Bangor International Airport show about 7,600 heating degree days a year, a January average of 18.5°F and roughly 75 inches of snow. Fuel oil or kerosene still heats close to half of Bangor's occupied homes, per Census estimates, with utility gas around a fifth. An energy audit with a blower-door test shows where an old house loses heat, and insulation work may qualify for Efficiency Maine rebates.

Old cellars and indoor air

A stone or brick cellar gives off moisture all summer, and in a multi-unit building that damp air rises into every apartment above it. Musty stairwells, white mineral bloom on the walls and mold on the first-floor joists are common signs. Drying the basement comes first; certified mold removal then deals with what has already grown. Maine CDC reports that at least a quarter of homes tested anywhere in the state have radon problems, so a test before sealing up a basement is worth doing.

Permits and neighbours

Building, plumbing and electrical inspections in the city go through Bangor's Code Enforcement office. Nearby, the same services reach Hampden, Hermon, Brewer, Orono and Holden.
