Failed sealant around glazing and joints is one of the most common causes of water ingress in modern buildings. We remove and replace facade and window sealants, seal movement joints and waterproof external walls, working at height where needed.
Sealants are the flexible joints that keep water out where two materials meet: around windows, along curtain walls and across movement joints. When they crack or come loose, water finds its way in.

We check the joints and find the cause of the failure.
Remove
We cut out the old sealant completely and clean the joint.
Prepare
We prime the surfaces and fit a backing rod where the joint needs one.
Seal
We apply the specified sealant to the correct depth and tool it to a neat, smooth finish.
Check
We inspect every joint before we hand over.
