Mastic man in Lewes

Resealing and mastic work across Lewes

Lewes is full of old buildings that have been altered, extended and refitted over centuries, and their sealant is often the newest thing in them. If you need a mastic man in Lewes, Mr Mastic covers the town and nearby villages from our base in Crawley. We reseal baths, showers, basins and kitchens, renew mastic around windows and doors, and put right failed joints left by earlier work.

In a historic house we take extra care. We protect surfaces, cut out old sealant by hand where needed, and pick a sealant to suit the material, whether that is timber, stone, render or modern tiles. We always remove the old bead completely before laying a new one; new silicone will not bond to old.

Timber frames, mathematical tiles and twittens

The centre of Lewes lies within the Lewes Conservation Area, and since 2010 the whole town has been inside the South Downs National Park, which handles planning here. The building stock is remarkably varied: timber-framed houses such as the sixteenth-century Anne of Cleves House, flint walls, Georgian frontages, and the mathematical tiles used in the eighteenth century to make older houses look like fashionable brick. The narrow twittens running off the High Street are lined with homes where space is tight and bathrooms have been fitted into whatever room was available.

Old timber frames move with the seasons, and walls rarely run true, so the gap between a bath and the wall can be wide at one end and tight at the other. A thin, rigid bead tears quickly. We fill deep gaps properly, use flexible sanitary silicone and seal with the bath full so it settles at its heaviest. Where earlier sealant has failed and caused damage, our remedial sealant service puts it right.

Victorian and twentieth-century streets around the centre, and newer homes on both sides of the Ouse, bring more familiar jobs: replacement windows whose mastic has hardened and showers whose original sealant has split.

Jobs we take on in Lewes

• Bathroom & kitchen resealing: Baths, showers, basins, wet rooms, worktops and sinks: old sealant cut out, mould treated and a new bead of anti-fungal silicone laid.
• Window & door mastic: Cracked or shrunken mastic around window and door frames, sills and patio doors replaced with a weatherproof sealant.
• Commercial & hotel sealant: Commercial washrooms, kitchens and wet areas resealed floor by floor, so only a few rooms are out of use at once.
• Remedial sealant & repairs: Failed, botched or over-sealed joints stripped out, the cause found and the joint resealed 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.
• New-build mastic & snagging: New-build bathrooms, kitchens and frames resealed where the original sealant has cracked as the house settles.
• Floor & skirting joints: Movement joints in tiled and concrete floors, and skirting gaps, sealed so they stay tidy and keep dirt out.
• Regrouting: Tired or mouldy grout raked out and renewed, and the internal corners finished in flexible silicone.
• Glazing & conservatory sealant: Conservatory, rooflight, glass panel and shower screen joints resealed with glazing silicone.
• Gutter, fascia & soffit sealing: Dripping gutter joints and end caps, and gaps at fascias and soffits, sealed with weatherproof exterior sealant.
• Sand mastic for sash & case windows: Traditional burnt sand mastic renewed around sash and case windows and doors in stone and brick.
