Mastic man in Crawley

Mastic and sealant work in Crawley

Mr Mastic is based in Crawley, so when you search for a mastic man in Crawley, you’re finding a firm from the town itself. We reseal baths, showers and kitchens, replace window and door mastic, seal external joints and look after hotels, offices and rented homes across the town and the villages around it.

Many of the jobs we use to explain our work are here. On a 1950s terrace on Crossways in Three Bridges, someone had sealed straight over old, failed sealant and mould had grown underneath. We took both layers out and resealed with Everbuild anti-fungal silicone in under three hours. It’s a good example of why we never seal over old silicone; our guide on putting new silicone over old explains the problem.

A new town built one neighbourhood at a time

Crawley was designated a new town in 1947 and grew as a set of neighbourhoods, each with its own parade of shops. West Green came first, from 1949, followed through the 1950s by Northgate, Langley Green, Three Bridges, Pound Hill, Ifield, Tilgate, Southgate and Gossops Green. Broadfield and Bewbush came in the 1970s, Maidenbower from the late 1980s, and Forge Wood is the newest of the town’s 14 neighbourhoods.

Each era brings its own sealant jobs. In the post-war houses, many bathrooms and kitchens have been refitted more than once, and we often find layers of old sealant, gaps where a bath has dropped, or replacement uPVC windows whose mastic has hardened after years of sun. On Harper Drive in Maidenbower, a kitchen’s 30-year-old sealant had shrunk and water was getting behind the worktop. We cut it out and used colour-matched sanitary silicone, with a food-safe product by the sink.

Newer homes have the opposite problem. In Forge Wood, a shower’s developer sealant failed after 16 months as the house settled and the shower was used every day. We removed it, primed the joint and resealed with sanitary silicone. If you’ve bought a new home and the sealant is already cracking, our new build mastic page explains what we check.
