Specialist Mastic Contractors in London
United Rope Access provides mastic and sealant work across London for offices, residential blocks and commercial buildings. Failed mastic is one of the most common causes of leaks on tall buildings, and rope access lets us fix it quickly and safely.

Mastic & Sealant Work at Any Height
Over time, sealant around windows and cladding joints cracks, shrinks and pulls away, letting water into the building. Our technicians cut out the old mastic, clean and prime the joint, then apply new sealant suited to the materials and movement.
We take on single repairs and full elevation resealing throughout London, tailored to each building's height, joints and condition.
Mastic & Sealant Work for London Buildings
Watertight joints for high rise, commercial and difficult to access properties
Window Perimeter Sealing
We cut out and replace failed mastic around window and door frames to stop water getting in around the glazing.
Cladding & Expansion Joints
We reseal cladding panel joints and expansion joints using sealants that allow for the movement of the building.
Leak Investigation
Where a leak has been reported, we inspect the joints from outside and target the repair to where water is getting in.
No Scaffolding Required
Rope access reaches every joint directly, so resealing costs less and causes far less disruption than scaffolding.
Repairs & Full Elevations
From a single window to a full elevation, we provide flexible mastic work tailored to your building and budget.
Mastic & Sealant Work at Any Height

IRATA Trained Mastic Technicians in London

Every job is planned around the building, its joints and the surrounding area before work begins, with photos of the finished work provided.
