Mastic man in Brighton

Mastic and sealant work in Brighton

Brighton and Hove is a city of flats, bay windows and bathrooms squeezed into old houses, and plenty of them need fresh sealant. We cover the whole city, from Portslade to Rottingdean, resealing baths and showers, replacing window and door mastic and sealing external joints that let the weather in.

We don’t patch. Whether it’s a shower tray in a top-floor flat or the mastic around a sea-facing bay, the old sealant is cut out, the joint is cleaned and dried, and a new bead goes on that suits the job. Sealant laid over sealant always fails, so we never do it.

Regency stucco, Victorian bays and converted flats

The seafront and the streets behind it are lined with Regency and early Victorian houses, many with painted stucco fronts, tall sash windows and iron balconies. Most have long been divided into flats. Inland, Victorian and Edwardian terraces climb the hills in Hanover, Round Hill and around the Seven Dials. Bay windows are a feature of many streets, and each bay has several frames, a sill and a roof joint where mastic does a lot of work.

In converted flats, bathrooms are often tucked into what used to be a box room or landing, and the bath or shower may sit on a timber floor that moves when it’s used. That movement tears a stiff bead of sealant. We use flexible sanitary silicone and fill the bath before sealing, so the bead is laid with it at its heaviest. In a building of flats, a failed seal rarely stays your problem alone: the water usually finds the ceiling below.

Many period windows here have been replaced with uPVC, and the sealant around them is now ageing. Where original timber sashes survive, the joint between frame and stucco or brick needs a sealant that suits both, and sometimes one that can be painted. Our window and door mastic page covers the frame types we work on.
