Your needs

Why would you like to replace your building's caulking?

One click — no information required

Our approach

No shortcuts, just quality work.

Before applying anything, we remove the old caulking completely. We clean, prep the surface properly — that's what makes the result last.

Every joint is hand-applied with care. We don't cut corners, and it shows.

Our services

Every type of caulking

Every surface has its own requirements. Here is the work our team performs daily, residential and commercial alike.

Expansion joint caulking

Movement joints on commercial and multi-unit buildings: elastomeric sealant that absorbs material expansion.

Sealed glass joints

Sealing the glass perimeter in its frame. If fog is trapped between the panes, the sealed unit itself must be replaced.

Window sill caulking

Protecting the sill under the window, the area most exposed to runoff and freeze-thaw cycles.

Rodent-proof caulking

Closing openings and cracks with resistant materials to block access to mice and insects.

Firestop caulking

Firestop sealing of penetrations and joints (walls, floors, ducts) to the fire-resistance standards required in construction.

Water infiltration protection through exterior caulking
Our products

Sealants built to last.

We choose our products based on your surfaces — brick, aluminum, PVC, wood. The right sealant in the right place makes all the difference.

We work with professional-grade products that withstand Quebec's frost, sun and humidity.

Adhesion matched to each surface
Freeze-resistant for Quebec winters
UV protection
Clean finish, easy to maintain

Fog between the panes?

If condensation sits between the two glass panes, the problem is likely the sealed unit rather than the exterior caulking. Our specialized division Thermos Horizon can replace only the sealed glazing without changing the whole window.

Permanent fog between the panes
Cracked or damaged glass
Frost inside the glazing

Is it the caulking or the sealed unit that needs replacing?

A leak around the frame, a cracked joint or a draft can point to a caulking issue. Permanent fog between the two panes usually means the sealed unit has failed. In that case, we can refer you to Thermos Horizon, our division specialized in sealed glass unit replacement.

How it works

Easy as 1, 2, 3

We show up, assess, and get the work done — often the same day. No nonsense.

1

Free inspection

We come to your place, check around your windows, doors and foundation. We tell you exactly what needs to be done.

2

Clear quote

Fixed price, no surprises. We explain what we'll do and how much it costs before we start.

3

Often in one day

Most residential jobs can be completed in a single day, depending on scope and site conditions. We show up on time and work cleanly.

We adapt

All types of buildings.

House, condo, commercial — we have the experience and equipment to caulk everything properly.

Houses

Windows, doors, foundations, flashing — we do a complete job on your home.

Condos and apartments

We work with condo boards for projects of all sizes.

Commercial

Offices, retail, warehouses — we adapt to your schedule and needs.

Why caulk

It costs less than doing nothing.

1

Stop water damage

Water seeping around your windows causes silent damage. Good caulking is your first line of defense.

2

Keep the bugs out

Ants, spiders, mice — they get in through cracks in your joints. We shut the door.

3

Lower energy bills

Leaky joints mean heat escaping. We seal them up and your bill goes down.

4

Your windows last longer

Moisture makes wood swell and damages frames. Proper caulking protects your investment.
