Mastic man in Chertsey

Mastic and sealant work in Chertsey

Chertsey is an old market town on a low terrace between the Thames and the River Bourne, and its streets hold an unusual number of listed buildings for a place its size. Mr Mastic covers Chertsey from our base in Crawley, and we reseal baths, showers and kitchens, replace window and door mastic and seal the external joints that let the weather into houses, flats and shops.

A lot of what we do here is putting right earlier work: sealant laid over sealant, the wrong product around a timber frame, or a quick patch that has already peeled. That is what our remedial sealant service is for. The old bead comes out completely, the joint is cleaned and dried, and the new one is chosen for the surfaces either side of it.

Sixteenth-century frontages and floodplain streets

The town centre is a conservation area with the character of a traditional small town: narrow frontages built hard against the pavement. It holds 42 nationally listed buildings, most dating from the 16th and 17th centuries, with more locally listed. On Windsor Street, number 25 is a Grade II* listed early 18th-century house in brown brick, and the Curfew House almshouses near St Peter’s church carry a keystone dated 1725. Guildford Street is the main shopping street, with flats above many of its shops.

In old buildings like these, walls and frames move with the seasons and timber windows have often been repaired many times. Stiff or cement-based fillers crack, so we use flexible sealants and, where the joinery is painted, a sealant that can be painted to match. Hidden bathrooms tucked into old upper floors are another regular job, as the floors flex and tear tired seals around baths and trays.

Beyond the centre, Chertsey spreads into later housing and out to the wooded slopes of St Ann’s Hill and the village of Lyne. Here the usual work is replacing ageing uPVC window mastic and resealing bathrooms and kitchens that have been refitted once or twice.

Jobs we take on in Chertsey

• Bathroom & kitchen resealing: Every joint in the bathroom and kitchen, from the bath edge to the worktop, stripped back and resealed with anti-fungal silicone.
• Window & door mastic: Window and door mastic that has dried out in the sun replaced with a weather-resistant joint that can move with the frame.
• Commercial & hotel sealant: Guest bathrooms, staff washrooms and kitchens in commercial buildings resealed in a planned order that keeps the site running.
• Remedial sealant & repairs: Second opinions on sealant that keeps failing: we strip it out, check for movement or leaks and reseal it properly.
• Fire-rated sealant: Gaps in fire-separating walls and floors sealed with fire-rated products, following the tested details for each one.
• External & façade joints: Expansion joints in brick, render and cladding cut out and renewed at the right depth so they can move without splitting.
