The attic insulation rebate Markham homeowners can claim right now is worth up to $1,250 — and if your upstairs rooms run hot in summer and cold in winter, or your Enbridge bill keeps climbing every January without an obvious reason, your attic is very likely why. Heat rises, and in a home with thin, settled, or original attic insulation, that heat escapes straight through the roof, taking your heating dollars with it.
This rebate runs through the standalone stream of Ontario’s Home Renovation Savings program. You don’t need to renovate your whole home or bundle the work with furnace, window, or wall upgrades to qualify — attic insulation on its own is enough.
Pro Insulation Contracting is headquartered right here in Markham, at 185 Riviera Dr, Unit 11 — not a crew driving in from Toronto or Vaughan. We built this guide to the attic insulation rebate in Markham specifically because generic, city-agnostic rebate content misses the details that actually matter locally: which neighbourhoods tend to have the oldest, most under-insulated attics, what the rebate is actually worth here, and how to get it claimed before winter demand backs up scheduling across the GTA.
Check your eligibility now — it takes a few minutes and there’s no obligation.
Why Markham Attics Are a Common Rebate Case
Markham’s housing stock isn’t uniform, and that matters for insulation more than most homeowners realize.
Established neighbourhoods — Thornhill, Markham Village, Cathedraltown, and parts of Unionville — were largely built to insulation standards that are decades out of date. Attic insulation in these homes has often settled, compressed, or simply never been topped up since the original build. These are the homes most likely to qualify for the top rebate tier.
Newer developments — Cornell, Wismer, Box Grove, and Angus Glen — were built to current Ontario Building Code. That’s a higher baseline, but “built to code” and “installed correctly” aren’t always the same thing. Even a newer attic can underperform if the air barrier wasn’t sealed properly during construction, and a professional inspection is the only reliable way to know where your home actually stands.
Wherever you are in Markham — Unionville, Cornell, Milliken Mills, Berczy Village, Thornhill, Markham Village, Cathedraltown, Wismer, Box Grove, or Angus Glen — claiming the attic insulation rebate in Markham starts the same way: a real measurement of your attic’s current insulation level, not a guess.
Attic Insulation Rebate Markham: How Much Can You Get?
The Home Renovation Savings program calculates the standalone attic insulation rebate at 50% of your total insulation cost after tax, up to a maximum. Your maximum depends on your attic’s current insulation level, measured in R-value:
- Up to $1,250 for attics currently at R-12 or below — the thinnest, most under-insulated attics, common across older Markham neighbourhoods
- Up to $1,000 for attics currently between R-12 and R-25
- Up to $800 for attics currently between R-25 and R-35
To qualify, your finished upgrade generally needs to reach R-50 or higher. Your exact tier depends entirely on your home’s starting point — which is why we measure it in person during a free inspection instead of quoting a number over the phone. You can review full program details directly on the Home Renovation Savings program website.

Do You Qualify?
Eligibility for the Home Renovation Savings attic insulation rebate generally requires:
- A home heated by natural gas, electricity, oil, propane, or wood
- A detached, semi-detached, townhouse, or condominium unit in Markham or elsewhere in Ontario
- Existing attic insulation below the program’s R-value thresholds
- A contractor who meets the program’s participation requirements to complete the work and file the paperwork
This isn’t a program you self-certify after the fact — eligibility is confirmed against your home’s actual, measured insulation level. That’s what a free in-home inspection is for.
What Kind of Attic Upgrade Qualifies?
Most rebate-eligible attic upgrades in Markham fall into one of three categories:
Blown-in insulation (cellulose or fiberglass) is the most common upgrade for Markham attics with settled or aging insulation. It fills gaps around joists, wiring, and awkward corners that batt insulation typically misses — especially common in older Thornhill and Markham Village attics.
Spray foam insulation combines insulation and air sealing in a single step, making it a strong fit for homes with drafts, uneven temperatures between floors, or complex roof lines.
Fiberglass batt insulation is a cost-effective option for straightforward, regularly shaped attic spaces without complicated framing — more common in some of Markham’s newer, simpler roof designs.
We recommend the right option after we’ve actually seen your attic, not before.
