Insulating Fennville Homes
Spray Foam Insulation in Fennville serves a small city in orchard and vineyard country. Point2Homes' census summary shows 19.3% of homes from 1939 or earlier, 14.7% from the 1980s and 19.6% from the 1990s. Only 50.1% of units are detached and 36.2% of occupied homes are rented.
Built on the edge of a swamp
Fennville was first built around a swamp, with buildings on higher ground, until fire destroyed the town in 1871. It was rebuilt with a railroad station, and farmers drained the swamp late in the 1800s. The name comes from Fenn's sawmill, built nearby in 1860. In 1981 the Treasury named Fennville an American Viticultural Area.
What we find
Older houses near downtown need walls and attics. Apartments and duplexes need hatch and attic sealing and rim joist foam. On the farms, packing sheds, barns and shops get closed-cell foam.
Low ground
Because the town was built on drained swampland, we check basements and crawl spaces for moisture before insulating foundation walls.
Small-town scheduling
Fennville jobs are often combined with work in Saugatuck, Douglas or Allegan on the same trip. Many foam installers carry a minimum charge, which HomeGuide puts at $1,000 to $2,000 or more, so bundling the attic and rim joist, or a house and an outbuilding, usually gives the best value.
Older homes downtown
The houses rebuilt after the 1871 fire and in the railroad years that followed are wood-framed with plaster walls, shallow attics and basements or crawl spaces on what was once wet ground. For those, we check wiring and moisture first, then dense-pack the walls, seal and insulate the attic, and foam the rim. Apartments and duplexes downtown need their hatches and attics sealed and rim joists foamed, ideally between tenants. Each area is priced separately, so owners can phase the work.
