Upgrade Your Toronto Home's Comfort and Efficiency with Blown-In Cellulose Insulation
In a city with weather as dynamic as Toronto'sโfrom sweltering summer heatwaves to bone-chilling winter cold snapsโmaintaining a comfortable and energy-efficient home is a constant challenge. If you're battling inconsistent temperatures, skyrocketing energy bills, or premature roof wear from ice damming, the culprit is very likely hiding right above your head: your attic insulation. For homeowners across the Greater Toronto Area (GTA), blown-in cellulose insulation represents the single most effective upgrade for transforming your home's performance.
At RenoHouse, we specialize in installing premium, eco-friendly blown-in cellulose insulation from industry-leading brands like Greenfiber and Applegate. This isn't just about adding a layer of fluff to your attic; it's a strategic investment in year-round comfort, significant energy savings, and a healthier living environment. Cellulose insulation creates a dense, seamless thermal blanket that meticulously fills every gap and crevice, drastically reducing heat loss in the winter and heat gain in the summer. By choosing RenoHouse for your cellulose attic insulation in Toronto, you're not only getting a superior product but also expert installation that qualifies for substantial government rebates, including the Canada Greener Homes Grant. Let us show you how this green, high-performance solution can revolutionize your home.
Insulation Showdown: Cellulose vs. Fiberglass vs. Spray Foam

Choosing the right insulation can feel overwhelming. Each type has its pros and cons, but for attic applications in the GTA, blown-in cellulose consistently offers the best combination of performance, value, and environmental responsibility. Hereโs a detailed comparison to help you understand why.
| Feature | Blown-In Cellulose (Greenfiber, Applegate) | Blown-In Fiberglass | Spray Foam (Closed-Cell) |
|---|---|---|---|
| Material Composition | ~85% recycled paper (newspaper), treated with non-toxic borates. | ~30-50% recycled glass, sand, and other minerals. | Petroleum-based chemical polymers (isocyanate and polyol). |
| R-Value per Inch | ~R-3.7 | ~R-2.2 to R-2.7 | ~R-6.0 to R-7.0 |
| Air Sealing Ability | Excellent. The dense, fluffy material settles into gaps and cracks. | Fair. Lightweight fibers can be moved by air currents. | Superior. Expands to create an airtight seal. |
| Fire Resistance | Superior. Borate treatment provides Class 1 fire rating; it chars, not melts. | Good. Naturally fire-resistant but can melt at high temps. | Good. Contains flame retardants but can release toxic fumes when burned. |
| Moisture Management | Good. Hygroscopic; can absorb and release moisture without losing R-value. | Poor. Loses insulating properties when wet and can promote mold. | Excellent. Acts as a vapour barrier, blocking moisture entirely. |
| Sound Dampening | Excellent. The dense pack structure is a highly effective sound barrier. | Fair. Offers some sound reduction but is less effective than cellulose. | Good. The rigid foam structure blocks airborne sound well. |
| Environmental Impact | Best. Highest recycled content, lowest embodied energy to produce. | Good. Uses recycled glass but is more energy-intensive to make. | Fair/Poor. Fossil-fuel derived, high embodied energy. |
| Installed Cost | $$ (Excellent Value) | $ (Least Expensive) | $$$$ (Most Expensive) |
The Takeaway: While spray foam offers the highest R-value and a perfect air seal, its high cost and environmental footprint make it a less practical choice for a full attic upgrade. Fiberglass is affordable but underperforms in air sealing, sound dampening, and real-world thermal resistance. Blown-in cellulose hits the sweet spot for Toronto homeowners, providing outstanding thermal performance, superior fire and sound resistance, and a best-in-class environmental profile, all at a highly competitive price point.
Our Meticulous 8-Step Installation Process
A high-quality product is only as good as its installation. At RenoHouse, we follow a rigorous, step-by-step process rooted in building science principles to ensure your new cellulose insulation performs at its absolute peak for decades to come.
- Initial Consultation & Attic Assessment: Our process begins with a thorough inspection of your attic. We measure the current insulation depth, identify any issues like moisture or pest activity, assess ventilation, and discuss your goals. We provide a detailed, transparent quote with no hidden fees.
- Comprehensive Attic Preparation: This is the most critical step. We carefully clear the attic space as needed. Our team then meticulously performs air sealing, using specialized foam and caulking to seal all penetrationsโpot light enclosures, plumbing stacks, wiring holes, and wall top platesโthat allow your expensive conditioned air to escape.
- Protecting Your Home: Your home's cleanliness is our priority. We lay down protective drop cloths from your front door to the attic hatch and seal off the work area to contain any dust.
- Equipment Setup: Our state-of-the-art insulation blowing machine remains outside in our truck. We run a long, flexible hose up to the attic, minimizing any disruption or mess inside your home.
- Venting & Baffle Installation: Proper attic ventilation is crucial for a healthy roof and home. We install baffles at the eaves to ensure the soffit vents remain clear and air can flow freely from the soffit to the roof vents, preventing moisture buildup and ice dams.
- The Blowing Process: With one certified technician in the attic and another feeding the machine, we blow the Greenfiber or Applegate cellulose insulation to a precise, uniform depth. We use specific techniques to ensure complete coverage, creating a seamless thermal blanket that leaves no gaps or voids.
- Final Inspection & Depth Verification: We don't guess. We use attic rulers placed throughout the space to verify that the insulation depth meets or exceeds the target for your desired R-value (typically R-60 for Greener Homes rebates). We ensure the coverage is level and consistent across the entire attic floor.
- Thorough Cleanup & Project Completion: Once the installation is complete, we remove the hose and all our equipment. We conduct a full cleanup of the work area, vacuuming any residual dust, and leave your home exactly as we found itโonly much better insulated. We'll then walk you through the finished work and provide all necessary documentation for your rebate applications.
R-Value Recommendations for Toronto (Climate Zone 6)

The "R-value" of insulation measures its resistance to heat flow. The higher the R-value, the better it insulates. As part of Climate Zone 6, Toronto and the GTA require high R-values to effectively combat our cold winters and hot summers. The Ontario Building Code sets minimums, but to maximize energy savings and qualify for rebates, we recommend aiming higher.
| Area of Home | Ontario Building Code Minimum | Greener Homes Grant Target | Approx. Cellulose Depth (Inches) |
|---|---|---|---|
| Attic | R-50 | R-60 | ~16.5 inches |
| Exterior Walls | R-22 | R-20 (if adding continuous) | N/A (for attic service) |
| Basement Walls | R-20 | R-22+ | N/A (for attic service) |
| Exposed Floors | R-31 | R-31+ | N/A (for attic service) |
For a typical Toronto attic, upgrading from a poorly insulated R-12 to the rebate-qualifying R-60 level is a game-changer. This level of insulation significantly stabilizes your home's temperature, slashes heating and cooling costs by up to 30%, and dramatically improves your family's comfort.
Maximize Your Savings: Rebates & Programs for Toronto Homeowners
Upgrading your insulation is one of the most financially savvy home improvements you can make, thanks to generous government and utility programs. RenoHouse is an expert in helping you navigate these programs to ensure you receive the maximum possible return on your investment.
Canada Greener Homes Grant & Enbridge HER+
In Ontario, the federal Greener Homes Grant is co-delivered with the Enbridge Gas Home Efficiency Rebate Plus (HER+) program. This streamlined approach allows you to access both federal and provincial funding through a single application process.
- Total Rebates: You can receive up to $10,600 in total rebates.
- Insulation Rebates: Attic insulation upgrades can qualify for up to $2,350. The exact amount depends on the R-value you add. Upgrading to R-60 typically qualifies for the maximum amount.
- EnerGuide Audits: You can receive an additional $600 to cover the mandatory pre- and post-retrofit EnerGuide home energy audits.
- Air Sealing Bonus: Achieving specific air leakage reduction targets, verified by your post-retrofit audit, can unlock additional rebates of up to $1,300. Our meticulous air sealing process is designed to help you hit these targets.
The Process is Simple:
- Book a pre-retrofit EnerGuide audit with a registered energy advisor.
- Receive your audit report with recommendations.
- Hire RenoHouse to complete the recommended insulation and air sealing work.
- Book a post-retrofit EnerGuide audit to verify the improvements.
- Receive your rebate cheque!
City of Toronto Home Energy Loan Program (HELP)
For homeowners in the City of Toronto, the HELP program offers another powerful financial tool.
- Low-Interest Financing: HELP provides low-interest loans of up to $75,000 to cover the cost of energy efficiency improvements, including insulation.
- Convenient Repayment: The loan is tied to your property and repaid over time via your property tax bill.
- Combine with Rebates: You can use a HELP loan to finance the project and still apply for the Greener Homes/HER+ rebates to pay down the loan principal.
RenoHouse is a registered contractor with the City of Toronto's HELP program, and we can provide all the necessary contractor details for your application.
Estimated Cost for Blown-In Cellulose Insulation in the GTA

Our installed price for blown-in cellulose insulation typically ranges from $1.80 to $3.50 per square foot. This variation depends on several factors:
- Target R-Value: Achieving R-60 requires more material than R-50.
- Existing Insulation: The amount and type of insulation already in place. Removal of old, damaged insulation is an additional cost.
- Attic Complexity: Attics with complex layouts, low slopes, or difficult access require more labour.
- Air Sealing Requirements: The extent of air sealing needed to optimize performance.
Here is a table of estimated project costs for upgrading a typical attic to R-60 in various GTA locations.
| City / Region | Average Attic Size (sq. ft.) | Estimated Cost (Low End) | Estimated Cost (High End) |
|---|---|---|---|
| Toronto (Downtown) | 800 - 1,100 | $1,440 - $1,980 | $2,800 - $3,850 |
| Scarborough | 1,000 - 1,300 | $1,800 - $2,340 | $3,500 - $4,550 |
| North York | 1,100 - 1,400 | $1,980 - $2,520 | $3,850 - $4,900 |
| Etobicoke | 1,200 - 1,500 | $2,160 - $2,700 | $4,200 - $5,250 |

The RenoHouse Difference: BPI Standards & The Power of Air Sealing
Many insulation companies take a "blow-and-go" approach. They show up, blow in the insulation, and leave. At RenoHouse, we operate differently. We adhere to the principles of the Building Performance Institute (BPI), which treats your house as an interconnected system. We understand that insulation cannot do its job properly in a leaky house.
Air leakage is the enemy of energy efficiency. Your home has a "building envelope"โthe barrier between the inside and outside. In the attic, this envelope is the ceiling. Every small hole from pot lights, bathroom fans, plumbing pipes, or electrical wiring is a pathway for heat to escape. This is called the "stack effect," where warm air rises and exits through the attic, pulling cold air in through the lower levels of your home.
This is why our mandatory first step is meticulous air sealing. Before a single piece of cellulose is blown, we seal these leaks. This crucial step:
- Maximizes Insulation Performance: It stops air movement *through* the insulation, allowing it to achieve its full R-value.
- Improves Indoor Air Quality: It prevents dust, allergens, and pollutants from the attic from being drawn into your living space.
- Unlocks Rebates: The EnerGuide audit measures your home's airtightness with a blower door test. Our thorough air sealing work is specifically designed to help you achieve the air leakage reduction targets required for bonus rebates.
By combining superior cellulose insulation with professional air sealing, we don't just make your attic warmerโwe make your entire home healthier, more comfortable, and more efficient.
