Mastic and sealant work in Woking
Woking is changing faster than most Surrey towns, with tall new apartment blocks in the centre and established estates all around it. Mr Mastic is based in Crawley and covers Woking, Horsell, Knaphill, St John’s, Goldsworth Park, Sheerwater and Old Woking, resealing bathrooms and kitchens and renewing mastic around windows, doors and external joints.
Most of what we see is simple wear: a bath seal gone black, a shower tray that’s started to leak, worktop sealant that’s shrunk away from the wall. We remove all of the old material, clean and dry the joint, and lay a fresh bead suited to the room. In kitchens that means food-safe silicone around the sink and hob areas; our kitchen resealing page has the details.
A railway town, a planned estate and a new skyline
The railway reached Woking in 1838, when the station stood on open heath well away from the original village at Old Woking. The modern town grew north of the line from the 1860s, after land near the station was sold off, and large detached houses went up at Hook Heath. Most of the Victorian centre has since been rebuilt, but older houses survive in the surrounding streets, many with replacement windows whose mastic is now decades old.
Between the wars the council built hundreds of homes, and after 1945 the London County Council built more than 1,200 houses at Sheerwater, which is now being regenerated with new homes. Goldsworth Park was approved in 1973, its first house was finished in 1974, and by 1988 there were around 3,000 homes, with the last completed in the 1990s. Many of those bathrooms are on their second or third refit, and settled baths and tired shower seals are common jobs.
Since 2012, high-density flats have reshaped the town centre, including the towers at Victoria Square. New flats need their sealant checked in the first year or two, and in apartment buildings some service penetrations call for fire-rated sealant rather than ordinary silicone.

Heathland, water and summer sun
Woking was built on heathland, and the Basingstoke Canal and the River Wey run through the borough. Homes near water or among tall trees can stay damp and shaded on one side, while south-facing frames and patio doors bake in summer sun. Both conditions shorten the life of external mastic. We use flexible weatherproof sealants outside, with backing rod in deep gaps, so joints can move with the seasons.
Town-centre hotels, offices and rental flats
Woking has a strong business base, from the McLaren Technology Centre to the head offices and serviced offices in the town centre. Office washrooms, kitchens and glazing all need sound sealant, and we can work early or late so staff areas stay usable.
The Hilton Woking opened in Victoria Square in 2024 with 189 rooms, and the town has other hotels and serviced apartments where bathrooms see constant use. Our guide to resealing hotel bathrooms explains how we keep disruption low. With so many flats in the centre, we also help landlords and letting agents between tenancies. Woking Community Hospital on Heathside Road and local care homes need hygienic seals too.

What we do in Woking
- 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: 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: Brickwork movement joints, render and cladding joints resealed with backing rod and flexible exterior sealant.

- Floor & skirting joints: Gaps under skirting boards, tile movement joints and concrete floor joints sealed with a product that suits the traffic.
- Regrouting: Shower and splashback grout replaced where it has cracked or stained, with silicone in the movement joints.
- Glazing & conservatory sealant: Glass-to-frame joints on conservatories, rooflights and shower screens cut out and resealed.
- Gutter, fascia & soffit sealing: Exterior joints at gutters, fascias and soffits resealed to stop drips and staining down the wall.

Questions from Woking
Do you cover Woking from Crawley?
Yes. Woking is part of our Surrey area, including Horsell, Knaphill, St John’s, Goldsworth Park, Sheerwater and Byfleet.
Our Goldsworth Park bath seal keeps splitting. Why?
Baths in older homes often move slightly when filled. We reseal with the bath full of water so the bead is laid with the bath at its heaviest.
Can you reseal bathrooms in a new town-centre flat?
Yes. We cut out failed developer sealant and reseal with a flexible sanitary silicone, which suits new buildings as they settle.
Do you use fire-rated sealant in apartment blocks?
Where a joint needs fire-rated sealant, we use a suitable product rather than ordinary silicone. We’ll explain what applies before we start.
Can you work in Woking hotels without closing whole floors?
We work room by room, so rooms go back into service as soon as the sealant has cured.
Do you work for letting agents?
Yes. We reseal between tenancies and when tenants report leaks or mould, and can arrange access through the agent.
