Steelton’s west-end homes are some of the oldest in Sault Ste. Marie — many built in the early 1900s for Algoma Steel families, with balloon-framed walls, shallow attics and stone or block basements that were never properly insulated. Combine that housing stock with Lake Superior winters, deep frost and rising heating bills, and it’s no surprise Steelton homeowners feel every draft. Spray foam seals and insulates in one step, and we connect you with a licensed local installer who knows exactly how these older Sault homes are built.
Where spray foam helps most in a Steelton home
- Shallow, under-insulated attics losing heat straight through the roof
- Cold, drafty walls in balloon-framed early-1900s houses
- Uninsulated basement rim joists — a major source of cold floors above
- Stone and block basement walls that sweat and feel damp
- Crawlspaces and additions that never get warm in January
- Bonus rooms and knee walls over unheated space
What spray foam insulation costs in Sault Ste. Marie
Pricing depends on the area, the thickness and whether it’s open-cell or closed-cell foam:
- Attic top-up (open-cell): roughly $1.50–$3.00 / sq ft
- Walls / rim joists (closed-cell): roughly $3.00–$5.50 / sq ft
- Basement or crawlspace: $2,500–$7,000+ depending on size and prep
- Whole-home retrofit: quoted after an on-site assessment
Closed-cell foam gives you the highest R-value per inch and doubles as an air and moisture barrier — which matters a lot in a Sault winter. The free quote gives you an exact number.

Steelton Spray Foam FAQ
Is spray foam worth it in Steelton’s older homes?
For most early-1900s Steelton homes, yes — they typically leak air badly and under-perform on insulation, so sealing and foaming the attic and rim joists usually pays back in comfort and lower heating bills within a few winters.
Open-cell or closed-cell for a Sault Ste. Marie winter?
Closed-cell is often the better choice here because it gives more R-value per inch and acts as an air and moisture barrier, which matters against Lake Superior cold. Open-cell can be fine for interior attic space. The installer will recommend per area.
Can you insulate my basement rim joists and crawlspace?
Yes — rim joists and crawlspaces are two of the highest-impact spots in an older Sault home and are a common closed-cell foam job. Sealing them cuts drafts and cold floors on the main level.
Are there rebates for spray foam insulation in Ontario?
Rebate programs change over time, and some utility or federal home-efficiency incentives require a pre- and post-retrofit energy assessment. Ask the local installer what’s currently available and what paperwork is needed before you start.
