Our building-science-driven insulation and air sealing solutions address heat loss, air leakage, and moisture issues at the source.


Veritas Insulation was born from a simple belief: every Ottawa family deserves a comfortable, energy-efficient home without breaking the bank or dealing with dishonest contractors.
Founded by Pierre Gauthier, Veritas began as a response to the poor service and inflated pricing he witnessed in the industry. Pierre's vision was clear: provide transparent pricing, use premium materials, and treat every home as if it were his own.
As a new insulation company, our core values guide everything we do. We believe in honest assessments, fair pricing, and workmanship that stands the test of time.

Pierre recently completed the attic insulation job on my home, and I couldn’t be happier with both the process and the results. He was very professional, responsive, and clearly passionate about what he does. He showed up on time, explained every step of the job in detail and also provided before and after pictures of my attic, and made sure I understood exactly what improvements were being made and why they mattered. He also did a very good job of cleaning up any mess once the job was complete as seen in picture. You can tell right away that Pierre takes real pride in his work. He didn’t just blow in insulation and call it a day — he took the time to air seal areas that were leaking, checked my attic vents, and made sure everything was up to code and done properly. The level of care and attention to detail was impressive and hard to find these days. The house feels noticeably warmer and more consistent throughout, and I can already tell the furnace isn’t running nearly as often. It’s one of those upgrades that just makes sense — more comfort, better efficiency, and long-term savings. It’s clear he’s building his business the right way — through honesty, hard work, and genuine customer care. If anyone in Ottawa or the surrounding areas is considering upgrading insulation, I can’t recommend Pierre enough. He’s reliable, friendly, and truly delivers top-notch results. Great guy, great work, and a great experience overall. It’s one of the smartest home upgrades you can make — better comfort, lower bills, and peace of mind knowing the job’s done right.
Pierre from Veritas insulation did a phenomenal job from inspection to completing the job in a timely manner. He is very thorough in his approach and passionate about doing the job perfectly. Very happy with the outcome. Thanks Veritas. Shamraiz family
I recently hired Pierre for an insulation job and I highly recommend his services. From his initial assessment to the completion of the work, Pierre was highly professional and thorough. He took the time to answer all my questions and provided a detailed quote on the spot. While his pricing was excellent, the most important aspect is the quality of the work; I am confident the job was completed correctly. I give his work a 10/10.
Very professional and timely. All expectations were met and when a slight problem occured, Veritas Insulation Inc did not rest until it was remedied. I would highly recommend them.
I was very sceptical when I was told that, under the new R60 standards, we were recommended to add at least 9 inches of insulation to our attic. Although we didn't have any ice spikes under our roof during the winter, we did have rooms on the second floor that were significantly colder than others. Yet our house isn't that old. It was built in 2002. When Pierre came to insulate the attic with cellulose, we noticed an immediate difference. The temperature upstairs is now stable in all rooms, making our lives more comfortable.
Job well done. No shortcuts as explained on site visit. Older homes need the upgrade and all issues where pointed out. Good cleanup.
Attic insulation helps maintain consistent indoor temperatures by reducing heat loss in winter and heat gain in summer. Proper insulation improves comfort, lowers energy bills, and prevents moisture and condensation issues.
Attic air sealing involves closing gaps, cracks, and penetrations that allow warm or cool air to escape. Sealing your attic reduces drafts, improves energy efficiency, and maximizes the effectiveness of your insulation.
Rim joists are the areas where the foundation meets the floor structure. They are common sources of drafts and cold air infiltration. Insulating and air sealing rim joists helps eliminate cold floors, prevents moisture issues, and reduces heating costs.
If your home has cold or hot spots, drafts, uneven temperatures, or high energy bills, your insulation may be insufficient. Veritas Insulation uses a thermal camera to identify air leaks and insulation gaps for a precise assessment.
Most attic or basement rim joist insulation and air sealing projects can be completed in a single day, depending on the size of your home and the scope of work. Our team will provide an accurate timeline during your free assessment.
