Sealant jobs we do in Caterham

Caterham has two distinct halves: Caterham on the Hill, the original settlement, and Caterham Valley, which grew in Victorian times around the railway terminus. Mr Mastic covers both from our base in Crawley, along with Whyteleafe, Chaldon, Woldingham and Warlingham nearby. We reseal baths, showers, basins and sinks, renew kitchen seals and replace failed mastic around windows, doors and outside joints.

A lot of Caterham’s homes are flats, and in a flat a leaking seal rarely stays your own problem. Water through a split shower bead can appear as a stain on the ceiling below within days. Taking out the old sealant completely and resealing properly is the surest way to stop it, and it is usually a quick job. In the Victorian houses of the Valley and the older homes on the Hill, the same care goes into baths, kitchens and window frames that have been patched more than once over the years.

Two towns in one: the Hill and the Valley

Caterham railway station, at the end of the line from Purley, opened in 1856, and Caterham Valley developed around it as a product of the Victorian age, with the larger shopping area and many period houses. Caterham on the Hill is older and has more listed buildings. In the 2011 census, the Hill had around 5,000 households, with more semis than any other type and over 1,200 flats. The Valley had about 3,500 households, of which nearly 1,400 were flats.

Two big redevelopments have shaped the Hill. The Caterham Barracks closed in 1995 and the site was redeveloped with a mixed estate of private and social housing, a supermarket and leisure buildings including The Arc arts centre. Most of the former St Lawrence’s Hospital site has also become housing. Homes on both sites include conversions of older institutional buildings alongside new-build houses and flats.

That mix brings varied jobs: compact shower rooms in flats, worn basin and sink seals, bath joints in Victorian houses with flexing floors, and cracked mastic around replacement windows. Our basin and sink resealing page covers the smaller jobs that are easy to put off.

Blocks of flats, shared entrances and the North Downs slopes

With so many flats, access is often the first thing to plan. We can liaise with managing agents about keys, entry codes and parking, and we bring everything up ourselves. In larger blocks and converted buildings, gaps around pipes and service runs through walls and floors may need sealing with a fire-rated product rather than ordinary silicone; our fire-rated sealant page explains when that applies.

Caterham lies within the North Downs, and homes on the higher, exposed slopes take more wind-driven rain. External mastic on those faces hardens and cracks sooner, so we cut it out and replace it with a flexible, weatherproof sealant, using backing rod in deeper gaps.

Schools, healthcare and town centre shops

Caterham has a range of schools, including Caterham School, on its present site since 1884, and De Stafford School, the main state secondary. Their changing rooms, kitchens and washrooms see constant use, and holiday working can be arranged. Caterham Dene, the NHS hospital on the Hill, sits among the healthcare and care buildings where clean, well-kept seals matter.

Church Walk, the shopping mall opposite the station, and the independent shops on the High Street on the Hill all have staff facilities that need resealing from time to time. We also work for landlords and letting agents with flats in the Valley. To book or ask a question, get in touch.

How a job runs

  1. Tell us about the job. A quick call or email with what needs sealing and where. Photos help us quote accurately.
  2. Quote and booking. We quote clearly before anything starts and fix a day that works for you.
  3. Preparation first. Old sealant out completely, surfaces cleaned, mould treated and the joint left dry.
  4. Lay the new bead. We apply the right product for each joint and tool it to a clean, even line.
  5. Leave it to cure. We tell you how long to leave it before use, and the work carries our one-year guarantee.
