Glass Sealant Joints Waterproofing for Leaking Glazing
Glass sealant joints waterproofing restores the thin lines of sealant that keep glazed roofs, skylights and canopies dry. The glass itself does not leak. The joints do. Sealant between panes and around frames is exposed to direct sun every day. Over the years it hardens, shrinks and loses its grip on the glass, and water passes through the gaps.
Leak Lock Insulation Contracting carries out glazing sealant repair on glass skylights, atrium roofs, canopies and glazed sections of commercial buildings. Facility managers, building owners and villa owners use the service when water drips from a glass roof or runs down the inside of a glazed wall.
Signs Your Glazing Joints Have Failed
For example, clients contact us for one or more of the following reasons.
- Drips from the glass roof: water appears along the joint lines.
- Cracked or crumbling sealant: the joint has hardened and split.
- Sealant pulling away: gaps between the bead and the glass edge.
- Discoloured or mouldy joints: moisture is sitting in the joint.
- Water inside frames: streaks down mullions and frame members.
- Misted glass edges: moisture reaching the edge of sealed units.

Our Glass Joint Waterproofing Process
Because every site is different, we adapt these steps to your glass sealant joint waterproofing project.
- InspectionBefore anything else, joints are examined and the leak path traced.
- RemovalThen, old sealant is cut out cleanly to the glass and frame.
- Cleaning & PrimingAfter that, surfaces are cleaned and prepared for good adhesion.
- Sealant ApplicationAs soon as that is done, new sealant is gunned in, tooled and finished neatly.
- Water TestFinally, after curing, the joints are water tested.
Materials & Methods
Joints are renewed with a glazing-grade sealant suitable for exterior exposure. New sealant is never applied on top of old: the failed material is removed first, because a fresh bead only bonds properly to clean glass and frame. Where glazing meets the roof, EPDM membrane forms the flashing.
In short, the work includes the following.
- Exterior glazing-grade sealant
- Backing rod in deeper joints
- Full removal of old sealant
- EPDM membrane at frame-to-roof junctions

Glass Sealant Joint Waterproofing FAQs
Questions about glazing sealant repair. Also, you can call us with any other question.
The sealant joints between panes and at the frames break down under UV light. Water enters through the failed joints, not through the glass.
It should not. New sealant does not bond reliably to aged sealant, so the old material is removed first.
Yes. Joints are masked, tooled to an even profile and cleaned, so the finish is consistent.
Our scope is joint sealing and waterproofing. Glass replacement is carried out by a glazing contractor, and we can reseal once new glass is fitted.
Sealant needs time to cure. We schedule the work for dry weather and advise the curing time for the product used.
