Building Caulking That Seals, Protects, and Performs
Sealing Building Envelopes for Long-Term Performance
Exterior caulking and sealant services for joints, frames, and transitions, stopping water intrusion and preserving the integrity of your building envelope.
Where Caulking Matters Most
Sealants play a key role in preserving envelope performance. Addressing these weak points helps prevent air infiltration, water damage, and energy loss.
We apply high-performance caulking at key exterior locations, including:
Window and door perimeters.
Control and expansion joints.
Cladding transitions and interfaces.
Curtain wall edges and penetrations.
Electrical and mechanical entry points.
When to Replace Building Caulking
Not all caulking failures are visible, but some signs should prompt immediate inspection:
-
Cracks or gaps along joints
-
Water staining around openings
-
Drafts near windows or doors
-
Mould or mildew growth indoors
-
Unexplained spikes in heating or cooling costs
Routine caulking replacement is a simple way to avoid more invasive repairs, and extend the lifespan of your envelope systems.
Stop Water Where It Starts
Failed caulking is one of the most common causes of water intrusion in commercial or residential buildings. When joints dry out, crack, or separate from the surface, moisture finds its way in, leading to mould, façade damage, and structural wear.
We treat caulking as a critical line of defence. Canmar restores envelope performance with targeted sealant application across high-risk transitions, helping protect against water, air, and thermal leaks that compromise comfort, efficiency, and durability.
