No one gets excited about insulation. It’s not exactly a glamorous upgrade, like a fancy kitchen reno or a shiny new bathroom. 

But when winter rolls in and your home feels like the inside of a snow globe, or summer hits and your attic turns into a sauna, you’ll wish you’d cared about it sooner.

We’ve been there—freezing under layers of blankets while staring at my energy bill, wondering why I’m paying so much to be uncomfortable. That’s when it hit me: good insulation is the unsung hero of a cozy, efficient home.

Lucky for you, Ottawa’s got some top-notch insulation pros who know their stuff. Even if it’s your attic, basement, or walls, these experts can help you fix those drafts, keep your toes warm, and maybe even lower those sky-high energy bills. 

Let’s dive into the top insulation companies that’ll make your home the coziest spot on the block!

What is the benefit of insulation in houses?

Insulation in houses helps improve energy efficiency by keeping warm air in during winter and cool air in during summer. 
This reduces heating and cooling costs, making your home more comfortable year-round.Additionally, proper insulation minimizes noise transfer and helps regulate indoor temperatures, creating a quieter and more consistent living environment.

O’Reilly Brothers has a reputation for handling tricky insulation jobs with care and precision. Clients often mention improvements in home comfort after their work.

For instance, one family whose attic upgrade made a noticeable difference in keeping the upstairs cool in summer and warm in winter.

We love that they’re thorough with their work—removing outdated materials, tackling mold remediation, and ensuring the insulation depth meets recommended standards. 

One customer even noted they vacuumed out old vermiculite with heavy-duty equipment, then topped everything up with fresh cellulose.

What stands out is the attention to detail in keeping the rest of the house protected during messy jobs, which is a big plus in our books. While most experiences have been smooth, we did notice a few minor concerns with scheduling consistency.

Still, if you’re looking for noticeable comfort improvements and solid workmanship, O’Reilly Brothers is a dependable choice for insulation upgrades in Ottawa.

Pros

  • Noticeable improvements in home comfort
  • Thorough work, including mold remediation and asbestos removal
  • Great care in protecting the rest of the house during projects
  • Fair pricing with clear communication

Cons

  • Minor scheduling inconsistencies
  • Occasional delays in project coordination

Professional, kind, and highly recommended

“These guys deserve the high reviews they get for a few reasons; kindness, responsiveness, reasonableness, quality work. A team came to remove potential asbestos tiles, they did excellent with a few small concerns that were remedied the very next work day. 

The exceptional quality of their customer service is why I will continue recommending them to all the single women homeowners I know who struggle with managing contractors and dealing with the unnecessary sexism that comes with it- 

In contrast, the O’Reilly team is professional, straightforward and hard working. 10/10 recommend.”

A seamless and tidy insulation upgrade

“Wonderful crews.  Had my old insulation removed(prior roof leaks).  Had spray foam added to attic deck.  Then baffles & cellulose.   

Each crew left my place tidy.  A wonderful experience for a much needed household upgrade.”

Panda Insulation delivers excellent attic upgrades, and clients love how thorough they are from start to finish. We noticed consistent praise about their quick response times, detailed estimates with photos, and precise execution.

One homeowner even said the crew left their worksite so clean it was “like they were never here,” which is rare when dealing with contractors.

We love that many clients noticed improved attic insulation, with one sharing their home felt warmer in winter and cooler in summer.

However, there were a few hiccups reported. One client was initially happy but noted that Panda Insulation never fully followed up, despite multiple calls. 

Another shared frustrations with an incomplete quote and lack of follow-up communication. 

Still, Panda Insulation delivers excellent workmanship, attention to detail, and noticeable results, making them a strong choice for insulation upgrades in Ottawa. Just be sure to stay on top of any follow-ups to avoid delays.

Pros

They were professional and worked efficiently, completing the job with high-quality workmanship. The insulation was installed perfectly, and I could tell they paid attention to every detail. 

Not only did they do an excellent job, but they also cleaned up thoroughly afterward. I highly recommend this service to anyone looking for reliable and top-notch attic insulation work!”

Strukt Solutions delivers top-notch insulation work, with a strong focus on spray foam upgrades that make a real difference. One homeowner called the temperature control improvements “a game-changer,” and we’ve seen plenty of similar praise for how effective their work is.

We like that Strukt shows up on time and sticks to the plan—one client even mentioned the team finished earlier than expected, which doesn’t happen often. 

While their quotes can come in a bit higher than other companies, clients say it’s absolutely worth the cost for the quality and long-term energy savings. As one customer put it, “every penny was well spent.”

The spray foam work itself is impressive. It’s clean, quick, and effective, with clients appreciating the noticeable results and tidy workspaces afterward. If you’re looking for reliable spray foam insulation in Ottawa, Strukt Solutions is a solid choice that delivers where it counts.

Jarrah Contracting Services is well-known for tackling real insulation issues and making homes noticeably more comfortable. 

Clients often mention how their attic upgrades eliminated cold spots—one even said their kids’ room finally feels warm in winter, which is a big win in our books.

What we love is the attention to detail. They don’t just add insulation; they go the extra mile by sealing electrical outlets and windows to stop heat from escaping.

Plus, the before-and-after photos clients share prove just how thorough and meticulous they are. It’s always great to see a company that takes pride in its work.

That said, we did notice a few hiccups with delayed quotes and scheduling, which left some clients frustrated. It’s worth double-checking timelines upfront to avoid any surprises.

Still, the results speak for themselves—better energy efficiency, warmer rooms, and no more drafts. If you’re looking for reliable attic insulation in Ottawa, Jarrah Contracting Services is definitely worth considering.

Pros

  • Comprehensive work, including sealing gaps and outlets
  • Eliminates cold spots and improves comfort noticeably
  • Polite team with great attention to detail
  • Before-and-after photos ensure quality transparency

Cons

  • Delays in scheduling and quote delivery
  • Occasional communication breakdown during busy periods

Knowledgeable team with excellent results

“I will definitely recommend JCS for their excellent work at my house. Jay and the team is quite knowledgeable in providing to the point guidance about insulation, weather stripping etc. in the house. 

They are quite courteous and did excellent cleaning inside the house after the attic insulation was completed.”

-Samir Patel, Google Review

Clear communication and great insulation work

“We were really pleased with Jay and Manuel’s work. They visited our house and clearly explained what they would be doing, along with providing a quote. 

They then came back the following week and installed attic insulation, baffles and hatch. We strongly recommend!”

When it comes to home insulation projects, Ottawa Insulations is praised for their thorough work and attention to detail. 

Clients often highlight Kevin’s in-depth inspections—he doesn’t just glance around but checks vents, hidden spots, and even potential mold issues to ensure nothing gets missed.

What sets them apart is their commitment to transparency. One homeowner noted how they received before-and-after photos and videos of the attic work, giving them full confidence in the job. 

Their pricing is competitive, and clients love that Kevin honored quotes even when projects were delayed due to unrelated repairs. That kind of reliability is a big win.

While the work quality gets high marks, a couple of clients noted minor hiccups, like cellulose left on clothes near the attic hatch. Another raised concerns about review incentives, which might not sit well with everyone. 

These are small things, but they’re worth keeping in mind.

Still, Ottawa Insulations earns strong recommendations for attic upgrades, basement insulation, and beyond. 

Pros

  • Thorough inspections, including hidden attic issues
  • Transparent service with before-and-after photos
  • Competitive pricing with honored quotes
  • Quick, clear communication

Cons

  • Minor cleanup issues, like cellulose left on clothes
  • Concerns about incentivized reviews

Noticeable improvement and clean installation

“Great work by Ottawa Insulations.  They had a good look of my attic during the quote and let me know what was needed and addressed my concerns.  

They did a great job on the install.  There were a lot of tight spaces to get into and install extra baffles (4/12 roof).  It was hard to notice the difference (fall season) until the first frost. 

I could visually see how much of an improvement the work made.  No more hot spots to worry about.

Highly recommended. Side note, there was nothing to clean up after the install as well.”

-Paul Benish, Google Review

Efficient crew with impressive results

“Two man crew of Mohamed and Josh worked efficiently and effectively to do the attic insulation upgrade.  They cleaned up very well.  

I was surprised how quiet the house was when insulation was being blown in.  Mohamed provided several videos of the work being done and completed.  Very pleased with the job.”
