Getting to Know Harpswell
Harpswell has more coastline than any other town in Maine — about 216 miles of it, spread across a long peninsula and dozens of islands. It is also home to the Bailey Island Bridge, built in 1927–28 from granite slabs stacked in an open cribwork that lets the tide flow through — the only granite cribstone bridge of its kind in the world.
All that shoreline means nearly every Harpswell home lives with salt air, wind, and weather off the water. We choose equipment and mounting locations accordingly, so systems on Orr's and Bailey Islands last as long as they should.
Harpswell Homes and What They Need
Harpswell's housing is almost all detached houses, over 90 percent in Census estimates, spread along Harpswell Neck and Orr's, Bailey and Great Island. Of roughly 4,300 homes, about a third are seasonal, many of them old summer cottages on the water. The median build year is 1979; about one in five homes predates 1940, and roughly half predate 1980, while under a fifth were built after 2000. Many started as summer places and were converted to year-round use, which often leaves shallow crawlspaces, piping in unheated spaces and additions wired and plumbed at different times. Salt air adds its own wear to outdoor equipment and fittings. On older island houses, repiping and plumbing upgrades are often part of making a cottage livable through February.
Heating and Cooling in Harpswell
Harpswell heats with oil and propane, since no natural gas mains reach the peninsula. The latest Census five-year estimates show about 44 percent of occupied homes on fuel oil and about 34 percent on propane, one of the highest propane shares in the county, with wood around 9 percent and electricity about 7 percent. Surrounded by Casco Bay, the town is milder than inland Maine in deep winter, but it takes the full force of coastal wind, which matters for heat loss in drafty cottages. A tank of propane or oil also has to arrive over a single road on each neck. For a converted cottage, cold-climate heat pumps can cut delivered fuel, provided the outdoor units are mounted above drifting snow and out of direct salt spray.
Water Supply and Drains in Harpswell
Harpswell has no public water or public sewer. Every home relies on a private well and, apart from roughly 96 properties with overboard discharge systems, an individual septic system; the town's own study says public systems are seen as cost-prohibitive because of the jagged shoreline and shallow bedrock. Harpswell has no sand-and-gravel aquifers, so wells draw from fractures in metamorphic bedrock, and yields vary widely even between neighbours. Where fractures connect to the bay, heavy pumping can pull in salt water; one condo complex's well turned salty in 2017. Iron, sulfur and arsenic also occur naturally. Water quality affects plumbing equipment directly, and water heater replacement on a coastal well goes better when salt, iron and hardness are tested and treated first.
Power, Storms and Wiring in Harpswell
Harpswell is one of the most outage-exposed towns on Central Maine Power's system: long, narrow necks served by lines under heavy tree cover, facing open water on both sides. In the December 18, 2023 storm, with winds up to 65 mph, all but about 100 of the town's roughly 4,750 CMP customers lost power, and two days later more than 600 were still out. The October 2017 nor'easter, the largest outage event in Maine history, did similar damage along the coast. Because every house here is on a well, losing power means losing water too, and a well pump plus a boiler circulator is a small load a generator handles easily. Generator installation on the Harpswell islands works best with the transfer switch and fuel supply planned together.
