Rim Joist Spray Foam Insulation in Essex County
The leakiest part of your house, fixed in half a day. Two inches of closed-cell seals and insulates every rim bay permanently.
Ask where a house loses heat and everyone says windows. Energy audits keep pointing somewhere else: the rim joist — the band of framing where your floor structure sits on the foundation. It's riddled with joints and penetrations, sits right in the wind, and in most houses is 'insulated' with a scrap of fibreglass doing nothing.
Cold floors, drafty basements, a furnace that never rests — that's the rim joist talking. Two inches of closed-cell foam in every bay seals the air leaks and insulates to about R-12 with a built-in vapour barrier, in a single half-day visit.
It's the highest-impact insulation work you can buy for the area involved, and we do it across Essex County — often bundled with basement walls.

The Problem
Fibreglass Can't Fix a Rim Joist
The rim is an air leakage problem first and an insulation problem second. Fibreglass filters air; it doesn't stop it. Worse, warm interior air passing through batts condenses on the cold rim board — which is why pulled batts so often reveal damp, stained, or mouldy wood behind them.
The stack effect drives it all winter: cold air in low at the rim, warm air out high through the attic. Seal the bottom of the loop and the whole house tightens up.
Why It Works
Why Foam Is the Only Real Fix
- Seals every crack, gap, and penetration — air movement stops
- About R-12 at two inches with vapour barrier built in
- Stops condensation on the rim board — no more damp framing
- Warmer floors and a draft-free basement, immediately noticeable
- Half-day visit on most homes
- Never sags, slumps, or needs replacing

Common Questions
Most homes are a half day including setup and masking. Finished basements with closed ceilings take longer or may need access panels — send photos and we'll tell you what's involved.
