Question 6

How much does insulation cost in Mississauga?

Accepted Answer

Closed-cell spray foam typically runs $2.50–$4.50 per board foot installed, open-cell $1.50–$2.50 per board foot, and blown-in attic top-ups $1.80–$3.20 per sq ft. A typical 1,500 sq ft basement spray foam project in Mississauga lands between $5,500 and $9,500. Every Northstar quote is free, written, and all-in — no surprise charges.

Question 7

What R-value do I need in Ontario?

Accepted Answer

Ontario Building Code climate zone 5 calls for R-60 in attics, R-22 effective in above-grade walls, and R-20 continuous (or R-12ci + R-13 batt) in basements. Closed-cell spray foam delivers ~R-6 to R-7 per inch, open-cell ~R-3.7, blown-in cellulose ~R-3.7, and fiberglass batts R-3.1 to R-3.8 per inch.

Question 8

How long does the installation take in Mississauga?

Accepted Answer

Most residential spray foam jobs are completed in a single day. A basement or rim joist project typically takes 4–8 hours; a full attic conversion 1–2 days; a blown-in attic top-up 3–5 hours; an insulation removal adds about half a day. We protect the site, mask floors and windows, and clean up before we leave.

Question 9

What insulation rebates are available in Ontario?

Accepted Answer

Ontario homeowners can access the Canada Greener Homes Loan (interest-free up to $40,000), Enbridge Home Efficiency Rebate Plus (up to $10,000 for attic, basement and wall insulation upgrades), and the Oil to Heat Pump Affordability program when paired with insulation. All rebates require a pre- and post-retrofit EnerGuide evaluation — we help coordinate the energy advisor and paperwork.

Question 10

Open-cell vs closed-cell spray foam — what's the difference?

Accepted Answer

Closed-cell foam is rigid, water-resistant, vapour-impermeable, and delivers R-6 to R-7 per inch — ideal for basements, rim joists, crawl spaces, and exterior assemblies. Open-cell foam is softer, vapour-permeable, and delivers R-3.6 to R-3.9 per inch — best for interior walls and attics where sound dampening matters and a vapour retarder is installed separately. We help you choose the right product for each cavity.

Question 11

What warranty do you provide on insulation work?

Accepted Answer

All Northstar workmanship is backed by a 2-year written guarantee. Spray foam carries the manufacturer's lifetime material warranty (BASF v.5 and Elastochem Insulthane Extreme) and is registered through CUFCA's Quality Assurance Program — which requires the installer to be CUFCA-certified, like Northstar.

Question 12

How long does spray foam and other insulation last?

Accepted Answer

Properly installed closed-cell and open-cell spray foam last the lifetime of the building — 80+ years — without sagging, settling, or losing R-value. Blown-in cellulose lasts 20–30 years before a top-up may be needed. Fiberglass batts last 15–25 years if they stay dry and uncompressed. Northstar's installs are documented with daily CUFCA reports so your warranty stays valid.
