Building sealing
A matter of precision
When it comes to sealing exterior surfaces, everything is a matter of precision: every small detail makes a difference.
Our experts carefully remove old sealants and decontaminate surfaces, then apply new sealants to form perfectly watertight joints.
- No damage to surfaces
- Surface decontamination
- Ultra-precise application
- Watertight and durable joints
Long-lasting protection
The best sealants available
Since caulking creates a watertight joint between two surfaces, sealant choice must consider its adhesion to those surfaces.
We take care to use the best sealants available, based on the surface type they're applied to, to provide you with lasting protection.
- Maximum surface adhesion
- Contaminant resistance
- Excellent UV resistance
- Easy-clean finish

Frequently asked
What people ask us on the phone
- How often should caulking be redone?
- As soon as the sealant hardens, cracks or pulls away. A simple test: poke it with a nail. If it cracks instead of springing back, it has lost its elasticity and no longer seals.
- Can caulking be done in winter?
- Caulking is best done in dry weather above 5 °C: below that, the compound hardens and applies poorly. That is why the season matters when planning the work.
- Do you work on condos and commercial buildings?
- Yes. Single-family homes, condos and co-ownerships, commercial buildings: the work follows the standards and regulations that apply to each building type.
- Does caulking really change anything on the bill?
- Hot air leaks and cold air infiltration account for up to 25% of a home's heat loss. Sealing around openings is one of the most cost-effective things you can do.
