Expansion Joints & Joint Sealing Experts

BC leaders in commercial expansion joints for 15 years.

The BC Expansion Joints Specialists Contractors Trust

Bringing together materials with masonry, timber, concrete, steel and other structures calls for expansion joints that provide critical enclosure. Whether your project needs to meet requirements for acoustics, firestopping, watertightness or seismic needs, we offer unparallel joint sealing expertise.

To deliver expansion joint services of the highest quality, we maintain manufacturer training and we’re proud to provide purpose-designed Emseal, Tremco, and Watson Bowman products that are as durable as they are safe and sustainable.

GRM Sealants & Coatings Inc. provides expansion joint sealants to a range of commercial, industrial and multi-family residential projects across BC—deploying local crews from Kelowna, Victoria and the Lower Mainland. Whatever the project, we recognize the critical need for overall enclosure performance to extend the life and safety of your structure.

What They’re Saying

  • Excellent workmanship on their firestopping work. From packing mineral wool, applying firestopping sealant, and spraying firestopping material, the installation work is amazing, very clean, and neat. This really demonstrates that they put their pride and heart into the work. Their shop drawings and sign-off documents are very organized as well. They also provide detailed photos of the firestopping installation. That makes the project close-out stage smooth. Well recommended firm for the firestopping work!
