Since moving to the 6ix, my friend couldn’t stop complaining about his sky-high electric bill. After hearing him gripe for months, I told him to consult with a local pro, and the expert had one simple recommendation: attic insulation.
Turns out, adding insulation to your attic is crucial for keeping your home warm in the winter and cool in the summer—without your energy bills going through the roof!
Fast forward a few weeks, and my friend’s heating bill dropped, leaving him thrilled. To help anyone else battling high bills, here’s a quick guide to the best attic insulation services in Toronto!
How much does attic insulation cost in Toronto?
On average, homeowners can expect to pay between $1,500 to $2,500 for a standard attic insulation job. Spray foam insulation tends to be more expensive than fiberglass or cellulose options, but it offers better energy efficiency.
The cost can vary depending on factors like the size of your attic, the type of insulation used, and the condition of your current insulation.
How We Chose the Best Attic Insulation Services in Toronto
1. Four Seasons Insulation
Four Seasons Insulation has been helping homeowners in the GTA stay comfortable for over 10 years. They’re members of the Canadian Urethane Foam Contractors Association (CUFCA)—proof that they know their stuff.
We like that they only use Walltite ECO for foam insulation. Not only does it go beyond the National Building Code requirements, but it also offers thermal insulation, air sealing, and moisture proofing—all with just a single application!
If you’re looking for other options, they also offer blown-in cellulose insulation, made from shredded paper that can easily fill those hard-to-reach spaces.
And for a budget-friendly option, their fiberglass insulation, made from tiny glass fibers, is both affordable and low-maintenance.
While they offer great products, some customers have noted that appointments can occasionally get canceled or rescheduled.
My heating and air conditioning bill was cut by 70%
“I have an old house with mold issues and in the summer the Air conditioning runs non stop. I had a contractor rip out all the drywall. I wouldn’t normally take time to put a review but these guys deserve it. Mike and Paul spray foamed it about a year ago. I thought the job would drag out for a few days but they were in and out in one day. These guys barely even took a break. Extremely impressed at their attention to detail and professionalism. They spray-foamed all the walls and attic. The difference is unbelievable from how the home used to be. A year later and they solved my mold or moisture issues. A year later and my heating and air conditioning bill was cut by 70%. I am so happy with the work! Thanks guys!”

2. Spray Foam Kings
Spray Foam Kings is an owner-operated contractor specializing in insulation services.
One of their perks is their free estimate and inspection. This is a great chance to get expert advice on what type of insulation would be best for your home, based on the local climate and your unique needs.
Their main service offering is spray foam insulation, which is fantastic if you’re looking for a more energy-efficient home. And because it forms an airtight seal, the spray foam keeps out pollutants, allergens, and outdoor contaminants—a big win for anyone concerned about indoor air quality.
But if you’re looking for a quicker and more straightforward solution, they also offer blown-in insulation, which is easier to install.
One thing to keep in mind is that their attic insulation options are a bit more limited compared to other insulation companies.

“Spray foam kings Toronto Has to be one of the best spray foam companies I have ever used from their customer service to their staff on site, professional polite on time and very courteous.

Free estimates are offered first, making it easy to figure out what type of insulation fits your budget and needs.
Now, their specialty is spray foam insulation, which seals and insulates your entire attic, including beams, pipes, and ductwork. It’s a great way to lower energy bills.
They also offer blown-in insulation, which is more cost-effective and helps improve your home’s R-value—basically, how well your home resists heat loss.
As a cherry on top, EcoStar claims their modern insulation can last 80-100 years and can cut 15-50% off your electricity bills.
While they might be a bit pricey, they offer flexible payment plans through Financeit.

“Great experience with EcoStar to spray insulate our entire house. They were very professional, always on time and did not hesitate to answer our questions quickly.

Since 2008, Foam It has been providing spray foam insulation services to residential homes and commercial buildings in Toronto, Mississauga, Oakville, and more.
As the name suggests, their bread and butter is spray foam insulation. They’ve done their homework, looking into independent studies and government reports to make sure they’re using the safest and highest-performing insulation products out there.
They also promise to make your home more energy-efficient, effectively lowering your electric bills by around 40%.
Another cool perk is that the material is tough for critters to tear through. This means less need for harmful pesticides, which is a win for your home’s health and safety. In addition, spray foam helps prevent mold and water damage by sealing off areas where moisture might sneak in
We did hear about their workers being late to jobs, so maybe bring that up when asking about their services.

5. EcoComfort Insulation & Contracting
EcoComfort Insulation & Contracting specializes in attic insulation services aimed at making your home more efficient while lowering energy costs. They only use chemical-free, Canadian-approved materials, giving you peace of mind.
They specialize in blown-in cellulose insulation, which is fire-resistant, mold-resistant, and provides solid long-term performance with satisfactory R-values. This can help you save 30% to 40% on your annual utility bills.
The process is pretty straightforward: they arrive, set up their equipment, and run a large hose up into your attic, where a technician is ready to go.
Outside, another team member operates the insulation blower parked in your driveway or lawn. They feed bales of cellulose insulation into the machine, which fluffs it up before it’s blown into your attic.
Unfortunately, some customers mentioned low-quality work that needed to be redone. You might want to check their work thoroughly to see if it’s up to par.
Everything went smoothly, and they cleaned up afterwards
“I highly recommend this company! They were quick to come out to give a free quote but more importantly, they were very accommodating in regards to our schedule! We wanted our attic insulation done sooner than later. The work crew that showed up were polite and efficient. Everything went smoothly, and they cleaned up afterwards. You can’t go wrong using EcoComfort!”
