How Much Does Blown-in Attic Insulation Cost?
Blown-in Insulation Pricing in the GTA
Blown-in attic insulation starts at $0.99/sqft, making it one of the lower-cost options. Your final quote depends on the attic size, existing insulation and material you choose.
- Material: Blown-in cellulose vs. blown-in fiberglass: Cellulose is typically 10–15% less expensive and is eco-friendly (made from 80% recycled material). Fiberglass (Owens Corning AttiCat) is slightly more moisture-resistant and suitable for high-humidity attics. Both achieve R-60 at the same depth.
- Current insulation level: The deeper you need to go to reach R-60, the more material is required. Homes with R-8 to R-15 will have higher material costs but also qualify for more of the HRS rebate.
- Attic size: Standard GTA homes have 800–1,400 sqft of attic space. Larger homes cost more but also attract higher rebates.
- Attic condition: If mould, moisture damage, or old vermiculite is found, removal and remediation is required before new insulation goes in. We quote that work separately.
Blown-in Attic Insulation Cost per Square Foot (2026 Quick Table)
| Home Age | Cost per Sq Ft | 1,000 Sq Ft Attic | After Max $3,100 HRS Rebate |
|---|---|---|---|
| 2010 or newer | $0.99 | from $990 | $0 |
| 1980–2010 | $1.15 | from $1,150 | from $0 |
| 1960–1979 | $1.30 | from $1,300 | from $0 |
| Pre-1960 | $1.45 | from $1,450 | from $0 |
The average blown in attic insulation cost in Canada is about $1.50–$3.50 per square foot installed. Our dedicated GTA crews handle a high volume of work, so Toronto-area pricing starts at $0.99 per square foot, below the national average. Most eligible households recover a large share of the cost through the Ontario Home Renovation Savings (HRS) rebate of up to $3,100.
Is Blown-in Attic Insulation Worth the Cost?
For most Ontario homes, yes. An R-60 upgrade typically reduces heating and cooling costs by 20–30% and keeps upstairs rooms comfortable in July and January. It usually pays for itself in 3–5 years, or sooner with the HRS rebate. Our full contractor breakdown explains what attic insulation really costs in Ontario, line by line.
DIY vs. Professional Installation Cost
For a 1,000 sq ft attic, DIY materials cost roughly $500–$900. Renting a blower and doing the work yourself may look cheaper, but the full cost of DIY blown-in insulation includes uneven coverage, settled R-value gaps and missed air sealing. DIY work also does not qualify for the HRS rebate, which requires a licensed contractor. Compare both options in DIY attic insulation vs. hiring a pro. If your attic has old or contaminated material, also see our attic insulation removal cost guide.
After HRS rebates, most GTA families pay a fraction of the full blown-in insulation cost. Many pay nothing at all.

Types of Insulation for Your Attic
We blow loose-fill fiberglass or cellulose into the attic with specialized equipment. It fits around wiring, pipes and uneven framing, making it our most effective option for existing homes with these obstacles.
Blown-in insulation is our most-requested service across the GTA. Installation is quick, and the loose material reaches awkward spaces that are difficult to cover with batts.
- Best for: Most GTA homes, attic top-ups, quick installation
- R-Value: 3.0 – 4.3 per inch
- Typical cost: $1,750 – $1,950
? Not sure which type is right for your home? Our inspector will assess your attic conditions and recommend the best material, at no cost to you.
Batts are pre-cut panels of fiberglass or mineral wool that fit between joists and studs. They work well in attics with regular framing and few obstructions, helping reduce both heat loss and noise.
You can choose widths and thicknesses to suit your framing. Compared with standard fiberglass, mineral wool batts provide better fire resistance and sound control.
- Best for: New builds, standard-framed attics, noise reduction
- R-Value: 2.9 – 4.3 per inch
- Typical cost: $1,900 – $2,150
Spray foam expands after application to fill gaps and cracks. It has the highest R-value per inch and the strongest air and moisture barrier of the insulation options listed here.
Closed-cell spray foam is denser and provides a better barrier against air and moisture. Open-cell foam costs less and suits interior applications.
- Best for: New builds, maximum energy savings, moisture-prone areas
- R-Value: 5 – 6 per inch
- Typical cost: $1,900 – $2,100

Frequently Asked Questions
In the Greater Toronto Area, blown-in attic insulation costs $0.99 to $1.45 per square foot installed, depending on the age of your home: $0.99/sq ft for homes built 2010 or newer, $1.15/sq ft for 1980-2010, $1.30/sq ft for 1960-1979, and $1.45/sq ft for pre-1960 homes. Most GTA families recover a large part of the bill through the Ontario HRS rebate of up to $3,100, which can bring the effective cost per square foot close to zero.
Across Canada, the average cost of blown-in attic insulation runs about $1.50 to $3.50 per square foot installed, with a typical 1,000 sq ft attic costing $1,500 to $3,500 before incentives. Canada Energy Solution pricing in Toronto and the GTA starts at $0.99 per square foot, below the national average. Eligible Ontario households can offset up to $3,100 through the Home Renovation Savings rebate program.
Yes, for most Ontario homes. An R-60 blown-in upgrade typically cuts heating and cooling bills by 20-30% and eliminates ice damming and cold upstairs rooms. Payback is about 3-5 years, or sooner with the $3,100 HRS rebate. It also improves resale value and year-round comfort.
You can rent a blower and buy insulation, with materials costing roughly $500-$900. Professional installation is usually better value: a licensed crew handles prep, air sealing and even coverage to R-60. Only contractor-installed insulation qualifies for the Ontario HRS rebate of up to $3,100, which usually exceeds the DIY materials saving. See our full DIY vs professional attic insulation comparison for the numbers.
Blown-in insulation, also called loose-fill, is cellulose or fiberglass blown into the attic through a hose. Instead of fitting batts between joists, the installer fills gaps and corners with loose material to form an even thermal barrier. It is the preferred method for topping up insulation in occupied homes.
Both are excellent options for GTA attics. Blown-in cellulose is slightly denser, made from 80% recycled content, and performs slightly better in air-sealing. Blown-in fiberglass (Owens Corning AttiCat) is slightly more moisture-resistant and maintains its R-value better in high-humidity environments. Our inspector recommends the best material for your specific attic during the free assessment.
For blown-in cellulose, R-60 requires approximately 17–20 inches of insulation depth. For blown-in fiberglass, R-60 requires approximately 16–19 inches. Depth requirements vary slightly based on the brand and density of material used.
In most cases, yes. If your existing insulation is in good condition (no mould, moisture damage, or pest contamination), we blow the new material directly on top, adding depth until the R-60 target is reached. If old insulation is damaged, we first remove it before installing new blown-in material.
Yes. Blown-in insulation is the primary material used in HRS rebate-qualifying upgrades in the GTA. Both blown-in cellulose and blown-in fiberglass qualify, provided the installation reaches at least R-50 (we target R-60 as standard). Canada Energy Solution has a 100% rebate approval rate for qualifying families.
Most standard GTA homes are completed in 4–6 hours. Larger homes or those requiring old insulation removal may take a full day or two days. Your project timeline will be confirmed during the free assessment.
No. Our crew seals the attic hatch and all penetrations before beginning work. The blowing equipment is self-contained, and all material stays in the attic. We protect hallway floors and clean up any incidental dust before leaving.
We serve the entire Greater Toronto Area including Toronto, Mississauga, Oakville, Brampton, Vaughan, North York, Scarborough, Etobicoke, Hamilton, Guelph, and over 20 surrounding communities.
Blown-in Attic Insulation in Toronto & GTA
Our inspectors recommend blown-in insulation for most Ontario attics. The loose material fills gaps around irregular framing and awkward knee walls, reaching spaces that fiberglass batts leave exposed in older homes.
Blown-in insulation, also called loose-fill insulation, uses air pressure to distribute cellulose or fiberglass throughout the attic. It forms a continuous thermal barrier without cold bridges. Ontario's HRS rebate program favours this method for attic upgrades, with up to $3,100 back for qualifying families. Upgrading an attic that still relies on old fiberglass batts can bring both rebate and energy savings.
Canada Energy Solution has upgraded thousands of attics across Toronto, Mississauga, Hamilton, Oakville, Vaughan and nearby communities over 20+ years. We are an Owens Corning certified contractor with a 4.9 Google rating. We guarantee our R-value targets and handle all the rebate paperwork.

Cover quite lot of the cost
My 20 year old house had tempriture problem on some of the bedroom for many years, though it's time for us to top up the insulation in the attic, there comes John the inspector, I got his number from my colleague, he came and check my attic the very next day I called him and luckly he found out I can be qualified for the government rebate program to cover quite lot of the cost for me, he patiently walked me through the details and helped me do the application.
-Rajat Aggarwal-
Very courteous and professional
I got inspector John's number from my friend who have had his service before. He responsed very quickly, called me the same date, and came visit my house the next day. He was very courteous and professional, checked many places in my house and dignosed where the problems are coming from, turns out I only had less than 7" of the insulation on my attic, and its unevenly distributed everywhere, even saw..
- Keyvan Mosharraf -
Increased to 21 inches
I had my attic insulation increased to 21 inches last weekend. I was skeptical at first when Jakey told me about the numberous benefits of increased attic insulation. Right now, I think the upper rooms feels much warmer and the furnace seems to be running less as well.
