Top 6 Insulation Services in Ottawa
Does it feel extra chilly or oppressively hot at home even if the weather is mild? Chances are you’ll need to replace or have extra insulation installed ASAP.
Today we’re going to review some professional insulation companies in Ottawa. They were selected for their dependability, reputation, reliability, and cost-effective solutions.
But first, let’s take a closer look at how much insulation services typically cost.
How Much Does Insulation Cost in Ottawa?
A lot will depend on the kind of insulation you’ll be getting. Different types have various ranges of R-values (or thermal efficiency) which will affect their price tags in turn.
We made a table below to show the estimated costs of some popular types by the square foot along with their installation fees. You can use any online contractor calculator to compute how much you’ll be spending per square foot of insulation material.
An initial estimate by a reputable contractor can also determine the condition of your home/workplace, how it was built, and its insulation needs. The thicker the insulation application is, the higher its cost will be.
Of course, the company you’ll pick out will play a big role in your invoice, as well.
The figures below represent national averages, but fees can fluctuate with labour, overhead, and operation costs per contractor.
INSULATION TYPE/SERVICE | ESTIMATED COST |
Spray foam insulation | $5 – $7 per square foot Installation $360 – $650 |
Fibreglass insulation | $.75 – $1.50 per square foot Installation $175 – $265 |
Dense-pack insulation | $2 – $3 per square foot Installation $145 – $195 |
Blown loose-fill insulation | $2 – $3 per square foot Installation $145 – $195 |
Soundproof insulation | $1.75 – $3 per square foot Installation $175 – $265 |
Initial estimates | Typically free |
As the last item in the table indicates, most companies offer free initial estimates for their clients. That’s the best time to clarify all the costs and fees you’ll be expected to pay.

Customer Reviews
Comfort Insulation has some positive reviews from past clients:
“Arrived as booked, friendly and did the job well, cleaned up well, left.” – Lori K.
“We recently bought a townhome in Mississauga. The attic insulation was original and had settled to less than four inches in most places. Paul Baldwin came out to inspect and shortly thereafter sent in his team to install the new insulation. They installed several baffles throughout the attic and increased our insulation to R50. Ashley and Steve were professional, quick (within 2.5hrs.) and very clean leaving little residual to clean up. I would recommend them to anyone needing insulation.” – Robert W.

Want Stewart Roofing to fix your insulation? First, read the following client feedback:
“I have dealt with Stan many times, these guys do great work and are very professional. I would highly recommend them. Just remember you get what you pay for, I got many quotes when I replaced my roof. Stan’s quote was very realistic.” – Rick
“We purchased our home and the roof was in need of replacement. We met Stewart Roofing at the Ottawa Renovation show in the spring of 2014. We were impressed right away with the sales representative’s knowledge of their trade and as well of the quality of the Owens Corning Shingles. We booked an appointment with the sales team to obtain an estimate, which we found to be priced quite well given the exceptional quality of the shingles. We informed Stewart Roofing that our schedule would be quite challenging as we had other renovations taking place at the same time and knowing this they agreed to work with us to fit the roof into our renovation project. Once the installation date had been chosen the roof was installed on time and under budget! The quality of craftsmanship is evident and the new roof looks fantastic. The removal of our old roof and installation of the new shingles only took 2 days to complete and the waste bin was removed on the third. I highly recommend Stewart Roofing to anyone in need of a new roof. If you have a chance to call the office and speak with Bonnie, she is just a lovely lady and was instrumental in assisting with the timing of our roof install. All in all, a fantastic experience and money well spent.” – Bonnie
