Multi Purpose Sealant Solutions - Firestopping/Waterproofing

Interior Caulking & Sealant

Lockhart Sealant Ltd. prides itself on handling interior caulking workloads efficiently with top-quality aesthetics.

Properly sealing interior windows, bathrooms, kitchens, baseboards and cabinetry improves airflow and helps prevent water damage.

Exterior Caulking & Sealant

Windows, doorframes, and vents on the exterior of any building in Canada should have adequate industrial strength caulking products to ensure tight seals.

Water and Wind are powerful forces that whip away energy ratings and cause costly repair bills. Avoid these problems by hiring the experts at Lockhart Sealant to provide proper sealant and waterproofing applications.

Joint Sealing

Buildings are most vulnerable to water & wind damage at the joints.

With our best-in-class products and wide portfolio we can offer a custom-tailored solution for your joint sealing project.

Joint sealing amounts to a fraction of total construction costs on any large building project. In case of moisture infiltration, the cost of repairing damage is considerably higher than the initial installation price.
