Sealant replacement in Vancouver
We cut out failed caulking and reseal window, panel and flashing joints from ropes or a swing stage. Silicone and polyurethane systems, primed and tooled to the manufacturer’s joint design.
Joints we replace
Exterior sealant lasts 10 to 20 years, depending on the product and the exposure. After that it cracks, pulls off one side of the joint and lets water behind the cladding.
- Window to concrete
Perimeter joints around window wall and punched windows, the most common leak path on a tower.
- Window to flashing
Head and sill joints where the frame meets sheet metal.
- Panel reveals and brick
Metal panel reveals, brick to concrete and control joints.
- Curtain wall
Wet seals over worn gaskets and stack joints.
- Firestop and interior
Tilt-up panel joints, door sills, bathrooms and baseboards on new builds.
Questions about sealant replacement
Short answers. Call us for the long ones.
How do I know the sealant has failed?
Look for cracks along the middle of the bead, gaps down one side, or sealant that has gone hard or chalky. Water stains inside below a window are a late sign. We can inspect from ropes and mark every failed joint on your elevations.
Can you work in the rain?
No. The joint must be dry for primer and sealant to bond, so in a Vancouver winter we plan around the forecast and seal the weather side first.
Do residents need to do anything?
Keep windows closed on the drop we are working that day and clear the balcony edge. We post a schedule by elevation before we start.
Which sealant do you use?
The one your envelope consultant specifies, or a silicone or polyurethane matched to the substrate when there is no specification. We keep the batch numbers for the warranty.
Finished sealant joints
A joint is done when the bead is tooled flat to both sides and the backer rod sits at the right depth. These are ours.
