Nothing says "vintage character" like finding yesterday's news stuffed in your walls.

Newspaper was a common insulation material decades ago, and it worked about as well as you'd expect. If your walls could talk, they'd probably ask for a retrofit.

The good news? Grants and rebates are often available to help cover that upgrade.

Not sure what insulation solution is right for your project? Let's talk.

Insulation is in. The drywall is stacked and ready to hang. 🏡

This is the stage where the work disappears behind the walls, and it's the stage that decides how warm and quiet the home will be for the next 100 years. Our crew sealed every wall, ceiling and window edge before the next trade arrived.

Insulation and fire protection aren't separate conversations. They're part of the same job.

Fire Prevention Day is a good reminder that what's inside your walls matters for more than comfort and energy bills.

Thermo Seal Insulation Systems also handles fireproofing work, using code-compliant coatings to protect spray foam and other materials the way building codes require.

Is your attic insulation costing you?

As temperatures drop, proper attic insulation can make a big difference in how comfortable your home feels and how much heat you lose.

We’ve seen attics where insulation looks like it reaches the required depth near the hatch, but tapers off elsewhere, meaning homeowners may not be getting the coverage or R-value they paid for.

At Thermo Seal, we do it right. We make sure your attic top-up is installed properly and consistently throughout the space.

🏠 Better coverage
🔥 Less heat loss
💰 Potential energy savings
❄️ A more comfortable home this winter

If you’ve been thinking about adding insulation, now is the time to take a look.

Getting to this job meant loading our truck onto a barge.

Some properties in cottage country don't have road access, so if the equipment can't drive in, it goes in by water. Barging lets us take on insulation projects that would otherwise be off the table.

Have an island or waterfront property that needs insulation work? Let's talk about how we'd get there:

This is a commission-based role with weekly draws, a company vehicle, fuel, and full benefits. You'll need at least 5 years of sales experience and solid knowledge of the insulation and construction industry, since this role means reading blueprints, quoting jobs, and managing client relationships from point of sale through final payment.

Some job sites don't have a driveway. They have a shoreline.

Cottage country is full of properties that are only reachable by water, and that doesn't rule out a proper insulation job. Thermo Seal Insulation Systems uses barging to get equipment and materials into locations a truck simply can't reach.

Have a hard-to-reach property that needs insulation work? Let's talk about how we'd get there.
