Caulking and sealant services in Montreal
LavPro provides professional caulking and sealant services in Montreal for commercial, residential, and high-rise buildings. Proper caulking helps protect your property against water infiltration, air leaks, and premature deterioration of the building envelope. Our team works on façades, windows, joints, and exterior building components to deliver long-lasting weather protection and improved energy efficiency — across commercial properties, condos, office buildings, and multi-storey structures.
Window perimeter caulking
We apply and replace sealant around windows to improve airtightness, prevent water infiltration, and maintain a clean finished appearance. Window perimeters are one of the most common failure points in older buildings — addressing them early prevents drafts, energy loss, and interior damage.
Expansion joint sealing
We seal exterior joints to protect against water penetration while allowing for normal building movement. Expansion joints need a sealant that can flex with thermal cycling — we select products engineered for Montreal's freeze-thaw conditions and apply them to last.
Exterior façade sealant and full replacement
On building façades, panels, and exterior transitions, old or cracked sealant can cause expensive damage if left in place. We remove deteriorated material, prepare the substrate properly, and apply new high-performance sealants suited to the building's exposure and movement profile.
Hard-to-access caulking with rope access
For elevated or difficult-access areas, our SPRAT-certified technicians use rope access methods to complete caulking work safely and efficiently — without scaffolding or lifts. This keeps setup costs low and minimizes disruption for tenants and surrounding traffic on high-rise and complex façades.
Why sealant maintenance matters in Montreal
Montreal's freeze-thaw cycles, summer heat, and winter wind loads put exterior sealants under constant stress. Failing caulking is one of the leading causes of water infiltration, energy loss, mold, and damage to interior finishes. Regular inspection and timely replacement of failing joints is one of the most cost-effective forms of preventive building maintenance — protecting both your envelope and the longer-term condition of windows, masonry, and interior assemblies.
