Brent has changed faster than almost anywhere in London
The streets around Wembley Stadium and Wembley Park have filled up with build-to-rent and residential towers in the last decade, and each tower is thousands of metres of sealant joint.
Window perimeters, curtain wall and cladding interfaces, balcony details, podium movement joints and internal silicone in every flat all need a sealant specialist. We price and deliver those packages for main contractors, façade firms and fit-out contractors, and come back later for maintenance re-mastic work.
South and east of the North Circular, Willesden, Harlesden, Kensal Green, Queen’s Park and Kilburn are dense Victorian terraces and conversions, where most of our window and door mastic, bathroom resealing and kitchen sealant work in Brent comes from.
Brent Civic Centre and Wembley Library, with their large glazed façades, are a good example of the curtain walling the borough is known for, and of why sealant inspections matter on buildings like them.

Sealant packages for Wembley Park and Alperton schemes
On a tower, the sealant package runs from the first window installed to the last flat handed over. We work to the façade drawings and the sealant manufacturer’s data, keep the joints consistent from floor to floor and record our work so the contractor has it for handover.
Inside, we seal kitchens, bathrooms, window boards and skirtings flat by flat, then come back for snagging.
- Façade and internal packages
- Manufacturer-approved preparation
- Floor-by-floor records
- Snagging visits before handover

Bathrooms, kitchens and windows in Brent homes
In Victorian conversions, bathrooms are often squeezed into small rooms with little ventilation, so silicone goes mouldy fast. We remove it completely, treat the mould and reseal with sanitary silicone, then explain how to keep it clean.
Outside, sash replacements and uPVC windows in Kilburn and Willesden often have cracked mastic that lets in the draught. We cut it out and reseal it in a colour that suits the brick.
We are also a polysulphide and polyurethane sealant applicator for commercial expansion joints, and use non-staining sealant on stone and listed buildings.
