Joint sealing keeps water out of the deliberate gaps a building needs to expand, contract and settle without cracking. Over time the sealant in these joints hardens, shrinks and pulls away, opening a direct route for rain. We rake out the old, perished sealant, clean and prime the joint faces, fit a backing rod where needed to set the correct depth, then gun in a fresh polyurethane or silicone sealant chosen for that joint’s movement and exposure. Tooled off neatly, the new seal bonds to both sides and flexes with the building, so windows, doors and expansion joints stay watertight through the seasons.

Expansion Joint Sealing
The movement joints that run through walls, slabs and floors are cleaned out and resealed with a flexible sealant that stretches and compresses as the building moves, keeping water out.
Window and Door Sealing
The gaps where window and door frames meet the wall are a common leak point. We seal the perimeter with a weatherproof sealant so driving rain cannot get in around the frame.
Construction Joint Sealing
Where separate concrete pours or building sections join, we seal the construction joint with the correct system so water cannot travel through the gap between the two elements.
Re-Sealing Perished Joints
Old sealant that has gone hard, cracked or lifted is fully removed and replaced with fresh flexible sealant, restoring the watertight seal instead of just smearing new sealant over the old.
Balcony and Parapet Joint Sealing
The joints where balcony slabs, copings and parapets meet are sealed against standing water and runoff, closing the gaps that so often let leaks track down into the rooms below.
Wet Area Joint Sealing
Around showers, baths and floor edges, we apply a mould-resistant silicone sealant to the perimeter joints so water stays in the wet area and cannot seep into adjoining walls and floors.
