Spray Foam Insulation in Franklin, IN

Spray foam insulation in Franklin often means working on older houses. Wikipedia says the town was platted in 1823 and incorporated as a city in 1861. Franklin College was established in 1834. The Franklin Commercial Historic District, the Martin Place Historic District and the Johnson County Courthouse Square are on the National Register. The population was 7,316 in 1950 and 25,313 in 2020, and the 2020 census counted 10,059 housing units.

Older homes near downtown and the college

The houses around the courthouse and the college include Victorians, foursquares and early 1900s homes. Many have balloon framing, stone or brick foundations, and attics that were insulated once, decades ago. We seal open wall cavities at the top and bottom, insulate attics and rim joists, and check wiring and foundation moisture first.

Learning from 2008

Wikipedia notes that during the June 2008 Midwest floods, Canary Creek, Hurricane Creek, Young's Creek and the buried Roaring Run all overflowed, damaging or destroying more than 100 houses. The city has since bought many flood-damaged homes and turned the land into green space. If your home is in a low area, crawl space and basement work should start with an honest look at water: grading, gutters, sump pumps and any signs of past flooding. Closed-cell foam does not absorb water, which is one reason it is used below grade, but it is not a flood fix.

Rain through the year

Franklin's 1991 to 2020 normals, listed on Wikipedia, show 44.97 inches of precipitation a year, with May and June the wettest months at about 5 inches each. Wet springs keep soils damp under crawl spaces. A sealed vapor barrier and closed vents help keep that moisture out of the house.

Newer homes

The subdivisions built since 2000 have their own list: rim joists, bonus rooms over garages, attic hatches. We handle those the same way as anywhere else in the region.

Foursquares and attic rooms

The early 1900s foursquares near downtown have large attics, sometimes finished as rooms, and deep porches. Finished attic rooms need their knee walls, short attic floors and slopes insulated, often with foam where loose fill cannot reach.

Student rentals

With Franklin College in town, some older homes nearby are rentals. Owners often want the work done between leases. We can schedule around tenants and keep the quote area by area so you can phase the work.
