Phone: +1 613 570 8890

Strukt Solutions is one of those companies we’ve found people just keep recommending in Ottawa when it comes to insulation. Their lifetime warranty on spray foam products is a serious trust-builder.
Plus, they handle everything from residential projects to larger commercial spaces, so there’s not really a job too big or small for them. Their services cover pretty much everything insulation–related—crawl spaces, attic, blow-in insulation, and even insulation removal.
Feedback from past clients has been super positive, with people talking about their professional staff, efficient work, and how clean everything is when the job’s done.
One thing we really liked was how they’ll help you figure out grants and rebates, like the Canada Greener Homes Grant. It’s such a helpful option if you’re trying to cut down on costs!
Now, the downside? They’re in high demand, so booking can be a bit of a struggle unless you plan way ahead.

Competitive pricing and great team
“Stukt Solutions did an amazing job with our basement walls, headers, and cantelivered overhang. They were very quick and professional, and the price was very competitive. They were also very patient and understanding as I needed to reschedule on multiple occasions. If you need any spray insulation done in your home, I can’t recommend them enough.”

2. Ottawa Insulations
Address: 2838 Carp Rd.
Phone: +1 613 882 3626
Business Hours:
- Monday to Saturday – 8 AM to 6 PM
Ottawa Insulations has been keeping homes and businesses comfortable and energy-efficient for over 25 years, and honestly, they’ve earned the trust they’ve got. What makes them stand out is their focus on eco-friendly options.
Like, they don’t just do the usual attic insulation or spray foam stuff—they offer everything from blown-in cellulose to fibreglass for all types of clients.
Here’s what we really like: they’ve got the whole process down to a science. They start with a free estimate (always a win), then handle removing old insulation before getting into the nitty-gritty og building a custom plan for your space.
That means you’re not left figuring it all out yourself—it’s smooth and straightforward. Plus, clients we spoke with said the crew shows up on time and even places down mats to protect the home before bringing in any equipment.
The one-year limited warranty is another bonus. On the flip side, we’ve noticed they’re sometimes slow to respond to inquiries.
Exceptional insulation upgrade
“Used to have R10, but Ottawa Insulation came in, 3 guys (busy season) Took me from R10 to R60 for a great price. Service was amazing, staff professional and kind, Polite, these guys deserve the bonus for sure! 😎 One hour later I have a fully insulated attic and after 3 days of rain and cold I can say it made a HUGE difference in the house for dampness and cold, Totally 10000% satisfied with the service and the staff. Kevin and Zack were great communicating even going above to call me to indicate a mail issue! I would recommend their crew any day of the week without hesitation!”

Excellent cleanup
“Absolutely perfect experience. Kevin Dao and the team were professional, courteous, efficient and cleaned up well after their work was completed! They even worked with me on a specific request I had when they didn’t have to at all.
10/10 would definitely recommend and use them again if need be in the future!”

Phone: +1 800 265 1914
Business Hours:
- Monday to Friday – 8 AM to 4:30 PM
Great Northern Insulation has been doing its thing since 1980, and honestly, they’ve got the whole insulation game locked down. One thing that really caught our attention is their focus on sustainability—they use materials with a lower embodied carbon!
We also commend their thoroughness! Their installations stick to manufacturer specs and come with third-party warranties, which is a nice safety net.
Plus, they guarantee all their work, so you can trust that they won’t cut corners. They’ll even help you figure out rebates or grants to ease the cost a bit—clients love them for this!
Notably, other clients often focus on their efficiency and professionalism, showing up on time, working nonstop, and keeping job sites spotless afterward. Those details matter.
That said, we’ve heard about a few scheduling hiccups, such as double booking and missed notifications. While rare, it could be frustrating for some customers.
Efficient service with attentive installers
“Friendly and efficient process throughout. Smooth and easy quotation process. Manpreet and Gursewak were our installers. They arrived on-time and were fantastic throughout the entire installation. They took great care in pre- and post- installation to keep the work area clean and tidy. They worked very well as a team, performed the work efficiently and addressed all of our questions and concerns. Highly recommended.”

Timely and meticulous insulation team
“I had Manpreet, Sukirat and Lakhveer install attic insulation and insulate the basement walls. They were on time, professional, and got the job done efficiently and neatly. They cleaned up really well afterwards. I’d definitely recommend them for anyone needing insulation work done properly and without hassle.”

Business Hours:
- Monday to Friday – 6 AM to 8 PM
- Saturday and Sunday – 6 AM to 5 PM
Panda Insulation is easily one of the go-to options for spray foam and residential insulation services in Ottawa.
They cover it all—attic insulation, basement insulation, and even soundproofing—all while using GREENGUARD Gold Certified products that keep dust low and your indoor air clean and safe for the family.
What really caught our attention, though, is their high-efficiency insulation materials that retain energy-saving R-values longer, so you’re not just saving energy now—you’re saving for years to come.
Clients often mention how responsive and professional their team is. From free, zero-obligation consultations to detailed quotes, their communication is spot-on.
Plus, the crew doesn’t cut corners—they take before-and-after photos, clean up after themselves, and even check in a few weeks later to make sure you’re happy with the results.
One thing they could work on is their appointment scheduling—it’s had a few hiccups here and there. The good thing is they are quick to sort things out.
Exceptional responsiveness and speedy service
“I contacted Panda Insulation for an urgent issue that needed to be addressed so we could meet conditions on the sale of a house. I called just before 7:00am and Brian took my call. He sent an inspector/estimator over within a few hours, sent the quote over same day and had the work completed within two days. This level of customer service is not easily found these days. Amazing service – thank you again.”
Rob Butterfield, Google Review
Efficient and highly professional work
“Took advantage of a free quote, and after chatting with Josh, it was an easy decision to go with Panda Insulation. It just also happened they did it the very next day. Quote was precise, no surprises, the crew worked very fast, clean and professional. Cleaned up very nice after. Highly recommended!!”

5. O’Reilly Brothers Ltd.
Address: 55 Capital Dr, Nepean
Phone: +1 613 224 1677
Business Hours:
- Monday to Friday – 8 AM to 4:30 PM
O’Reilly Brothers Ltd. has been around for over 45 years, so they’re already pros at what they do, whether it’s spray foam insulation, blown cellulose, or even more specialized services like fireproofing and insulation removal.
Here, they have a dedication to sourcing materials locally—both their spray foam and cellulose come from Canadian-made raw materials, which is a nice touch when you’re all about supporting local business.
We also found their service crews to be professional and efficient. When we get to tag along, they show up on time, work quickly, and don’t leave a mess behind—big bonus points there.
Energy savings also came up quite a bit while chatting with customers; some mentioned seeing noticeable drops in heating bills after the work was done.
What we weren’t too thrilled about was their after-service support. Once the work’s finished, the follow-up isn’t as strong as we’d like—it’s not like you’re left hangin, but it could definitely be smoother.
Exceptional problem-solving and thorough cleanup
“Oun and Victor from O’Reilly Insulation did a fabulous job today. They were professional, friendly, and timely. What impressed me the most was they discovered that a previous contractor had not connected a bathroom ceiling fan exhaust properly and as a result it was venting into the insulation in the attic not outside. If not resolved this could have caused real problems. However they identified the problem and made sure the fan now vents outside. Oun took the time to show me video of the work that they had done in the attic which looked complete and professionally done. Once they were finished, they did an amazing job of cleaning up. In fact, there was no trace of insulation left in the house. They were a fantastic team and I would not hesitate to have them back for any future work. Thanks Oun and Victor!”
