Mastic man in Chorleywood

Mastic and sealant work in Chorleywood

Chorleywood grew quickly once the Metropolitan Railway reached it in July 1889, and a great many of its houses are now well over a century old. Old houses tend to have bathrooms that have been refitted several times, frames that have been painted and repainted, and joints that have moved a little every winter. Mr Mastic covers Chorleywood from our base in Crawley, resealing baths, showers, basins and kitchen worktops and replacing tired mastic around windows and doors.

In a house of this age, the quality of the preparation matters more than the bead itself. We cut every trace of the old sealant out, clean the joint back to sound tile, enamel or timber, let it dry and only then lay new silicone or a suitable paintable sealant. If you have ever wondered whether it’s safe to run new silicone over the old, our guide on sealing over old silicone explains why we never do.

Voysey’s influence, Metro-land and Chartist cottages

The Chorleywood Station Estate is the clearest picture of the village’s growth. The land was bought in 1894 and sold in plots to local builders, and of its 203 houses about four in five are Victorian or Edwardian. Most are large detached houses, no two alike, and the architect Charles Voysey, who lived locally, influenced many of them. The area was made a conservation area in 1990, and its houses mix brick, render, roughcast, tile-hanging and timber sash windows, with steep roofs, bold chimneys and small windows set high under the eaves.

Those details are lovely, but they make sealant work fiddly. A roughcast wall meeting a timber sash leaves an uneven joint that a stiff bead won’t follow, and a painted frame needs a sealant that can be painted too. Inside, older bathrooms often sit on suspended timber floors, so baths move when they are filled and the wall joint splits.

South of the village, Heronsgate began as a Chartist settlement of 1846–47, with simple rendered cottages under slate roofs, and it has been a conservation area since 1993. Between these, the twentieth century filled in streets of Metro-land semis and later houses, many now with replacement uPVC windows whose mastic has hardened and cracked.

What we do in Chorleywood

• 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: Frame perimeters inside and out resealed with flexible, colour-matched sealant, with backing rod where the gap is deep.
• 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: Fire-rated and intumescent sealant around gaps, frames and service penetrations, to the product’s tested details.
• External & façade joints: Outside movement joints given new backing rod and a flexible, weatherproof sealant in a colour to match the wall.
• New-build mastic & snagging: New-build bathrooms, kitchens and frames resealed where the original sealant has cracked as the house settles.
• Floor & skirting joints: Skirting-to-floor gaps, tiled floor movement joints and concrete floor joints sealed with the right product.
• Regrouting: Shower and splashback grout replaced where it has cracked or stained, with silicone in the movement joints.
• Glazing & conservatory sealant: Conservatory, rooflight, glass panel and shower screen joints resealed with glazing silicone.
• Gutter, fascia & soffit sealing: Leaking gutter joints, end caps, fascia and soffit joints resealed with exterior sealant.
• Sand mastic for sash & case windows: Old sand mastic around sash windows and doors raked out and renewed with traditional burnt sand mastic.
