Two very different halves of one borough
Haringey splits roughly along the railway line, and the sealant work splits with it.
In the west, Highgate, Muswell Hill, Crouch End, Hornsey and Stroud Green are almost all Victorian and Edwardian houses, many turned into flats. Sash windows, bays, loft conversions and small bathrooms mean steady work in window and door mastic, shower resealing and kitchen sealant.
In the east, Tottenham Hale, Wood Green and Northumberland Park have some of the largest new housing schemes in north London, with towers and blocks that need façade joints, plot mastic and internal silicone sealed for contractors and developers.
Bruce Castle in Tottenham, Alexandra Palace above Wood Green and the art deco Hornsey Town Hall in Crouch End show how much older brick and stone the borough has, all of which needs non-staining sealant and careful prep.

We are working in the City now, on the new courts building at Salisbury Square: perimeter sealant between natural stone panels and window frames.
Sealing sash and bay windows in Victorian streets
Bay windows in Crouch End and Muswell Hill move more than flat walls, and the joint between the frame and the brickwork is often packed with old, hard filler that has cracked.
We take it all out, set backer rod for the right depth and use a soft, low-modulus mastic sealant that can move with the bay. On painted or rendered reveals we match the colour so the joint disappears.
- Old filler and mastic removed
- Backer rod for the right depth
- Flexible, colour-matched sealant
- Neat finish on painted reveals
Bathrooms and kitchens in Haringey conversions
In a converted flat a failed shower joint can leak straight into the flat below. We strip out the old silicone, check the tray and tiles, dry the joint and reseal it properly.
Landlords and letting agents across Harringay, Hornsey and Wood Green use us between tenancies to get bathrooms and kitchens ready on time.
We are also a polyurethane and polysulphide sealant applicator for commercial expansion and movement joints, and provide RAMS for site work.
