Spray Foam & Insulation Contractorsin Bloomington, MN
Trust Works insulates homes across Bloomington, from the mid-century neighborhoods off Old Shakopee Road to the newer builds near the Minnesota River bluffs. We air-seal and spray-foam the leaky attics and rim joists that make post-war homes hard to heat. Fully insured, 20+ years of experience.
The homes here, and how they leak heat.
Much of Bloomington went up in the 1950s and 1960s as ramblers, split-levels, and split-entries during the post-war building boom. These homes are solid, but they were framed to the energy standards of their day — thin attic insulation, no air sealing at the ceiling plane, and rim joists that were left bare.
Closer to the Minnesota River and along the bluffs, you also find a mix of newer construction and larger homes where vaulted ceilings and bonus spaces create their own insulation challenges.
Areas we serve in Bloomington
The right fix for Bloomington winters.
The classic Bloomington rambler or split-level usually has a shallow attic that has never been topped up and a rim joist you can feel cold air pouring through in the basement. Sealing the attic plane and spray-foaming the rim joist are the two highest-return upgrades we do here, and together they take the chill out of the lower level.
Split-level homes have extra transition points between floors where air leaks. We know where those hidden gaps are and seal them so the whole house heats evenly.
