Basement Spray Foam Insulation in Windsor & Essex County
Dry, warm, code-compliant basement walls with no poly and no mould risk. Most basements are a one-day job.
Finishing your basement? The insulation you choose before drywall decides whether the space stays dry and comfortable for decades or grows mould behind the studs.
Concrete is a moisture reservoir — it wicks ground moisture and releases it inward year-round. Fibreglass and poly against concrete builds a condensation trap: the assembly behind that musty basement smell everyone recognizes. Closed-cell foam is the opposite: it bonds to the concrete, can't absorb water, and at two inches acts as its own code-compliant vapour barrier.
We spray basements across Windsor, Leamington, Kingsville, and the rest of Essex County — most are a single day on site.
Served locally across Essex County — Leamington, Kingsville, Windsor, Lakeshore, Essex, and Chatham-Kent.
The Problem
Fibreglass + Poly + Concrete = Mould
Moisture moving out of the foundation gets trapped between the concrete and the poly, condensing in the fibreglass. Wet batts lose their R-value, feed mould, and rot the framing — invisibly, behind the finished wall, until the smell or the health complaints show up.
Cold floors and drafts are the same wall failing thermally: air circulating behind poorly-fitted batts strips heat from the space no matter what the thermostat says.
Why It Works
The Right Basement Assembly
- Bonds directly to concrete — no air gap, no convection loop, no drafts
- Unaffected by moisture — can't absorb water, can't feed mould
- Two inches = code-compliant vapour barrier, no poly needed
- About R-12 at two inches, R-18 at three — thickness spec'd to your project's code path, no thick furring
- Seals the rim joist zone where basements leak most air
- Passes inspection with documentation — inspectors see foam basements daily
How It Works
One Day, Start to Finish
Step 1: Quote
Wall dimensions and a couple photos get you a fast quote.
Step 2: Prep
We mask, protect, and prep — the space is ready to spray in an hour or two.
Step 3: Spray
Closed-cell to spec on foundation walls and rim joists.
Step 4: Frame Away
Cured and ready — stud walls and drywall can proceed on schedule.
FAQ
Common Questions
Either works — foam can go on bare foundation walls before framing (our preference; fully continuous) or into framed cavities against the concrete. If you're planning the project, call before you frame and we'll help you sequence it.
