More Than Just
Adding Insulation
A lot of homeowners assume attic insulation is a simple job: add more, save more. In reality, a proper attic upgrade involves several steps, and skipping any of them can leave you with the same drafts, cold rooms, and high bills you started with.
Space Insulation offers complete attic insulation and upgrade services across the GTA. That means we don't just add material on top of what's already there. We assess your attic, determine what it actually needs, and bring it up to current standards from the ground up.
Is Your Attic Meeting Ontario's Code?
Ontario's Building Code (SB-12) sets minimum insulation standards for attics, and for most homes across the GTA, that standard is R-60. If your home was insulated decades ago, or hasn't been touched since it was built, there's a good chance it's falling well short of that.
The tricky part is that most homeowners have no way of knowing where their attic stands. Insulation settles over time, gaps form around vents and framing, and older material simply doesn't perform the way it did when it was first installed. A free assessment is the easiest way to find out where your home actually sits, and what it would take to bring it up to code.
Custom Treatment
Top-Up or Full Replacement?
We'll Tell You Honestly
Not every attic needs to be gutted and started over. Some just need a top-up. Others need a full removal first. Here's the general difference:
A top-up usually makes sense when:
- Your existing insulation is dry, clean, and in reasonably good condition.
- You just need to add depth to reach current R-value standards.
- There's no sign of pest activity, mold, or water damage.
Full removal & replacement is needed when:
- The existing insulation is wet, moldy, or contaminated.
- There's evidence of pests (droppings, nesting material, damage).
- The insulation is old enough that its performance has significantly degraded.
- You're dealing with older materials that may pose safety concerns.

Our Scope
What's Included in a Complete Upgrade
A full attic upgrade with Space Insulation can include the following comprehensive steps.
Free assessment
We inspect your attic, check current insulation levels, and look for air leaks or moisture issues, at no cost to you.
Old insulation removal
If your existing insulation is contaminated or too degraded to build on, we remove it safely and prepare the space for new material.
Air sealing
Before adding new insulation, we seal the leak points that let heat escape: pot lights, plumbing stacks, and top plates. Insulation performs far better once these are addressed.
New insulation installation
We install new material to bring your attic up to R-60, using quality fiberglass or cellulose depending on your home's needs.
Ventilation check
Proper attic ventilation prevents moisture buildup and helps your new insulation perform the way it should long-term.
Rebates & Incentives for GTA Homeowners
There are provincial and utility-run programs that may help offset the cost of an attic insulation upgrade, depending on your home type, current heating source, and eligibility. Programs and amounts change over time, so rather than promising a specific number, we'll walk you through what may apply to your home during your free assessment and point you toward the current program details.

Clear Answers
Frequently Asked Questions
R-60 is the current Ontario Building Code standard for attic insulation in most of southern Ontario, including the entire GTA. It measures how well your insulation resists heat flow. Many older homes fall short of this standard, which means they're losing more heat (and money) than they should.
It depends on the condition of your existing insulation. If it's dry, clean, and undamaged, a top-up is often enough. If there's moisture, pests, or significant wear, a full replacement is usually the better long-term choice. We'll tell you which one your attic needs during the assessment.
No, eligibility depends on your home, your heating source, and current program rules, which can change. We'll help you understand what may be available, but we won't promise a specific rebate amount upfront.
Common signs include rising energy bills, cold or drafty rooms, ice damming along your roofline in winter, and visibly thin or uneven insulation in your attic.
We handle the complete process, assessment, removal (if needed), air sealing, and installation, so you're not coordinating multiple contractors for one upgrade.
