Your local mastic man for Sunningdale

Sunningdale fills the far south-east corner of Berkshire, right against the Surrey border, with Sunninghill to the west and Virginia Water Lake to the north. It is part of the Royal Borough of Windsor and Maidenhead, has its own station on the Waterloo to Reading line, and is crossed by the A30 London Road. Mr Mastic covers Sunningdale from our base in Crawley.

Many homes here have generous bathrooms: several en suites, walk-in showers and wet rooms finished in stone or large-format tiles, where a poor seal stands out and a leak can damage expensive surfaces. We take time over this kind of work, cutting out old sealant cleanly and finishing with a neat, even bead. Our wet room sealing page explains how we approach level-access showers.

Large houses, green edges and converted mansions

Sunningdale’s civil parish was created in 1894; before that the village was part of Old Windsor. Until 1995 part of it, known as Broomhall, lay in Surrey, split between Surrey Heath and Runnymede, before the whole village came under the Royal Borough. The village is ringed by green buffers, and its northern estates run up to the edge of Virginia Water Lake. About 5,300 people lived here at the 2011 census.

Alongside its family houses, the village has some striking conversions. Charters, a Grade II listed art deco mansion built in 1938, has been redeveloped as an apartment complex and spa. Coworth Park, a late 18th-century country house, is now a hotel. Buildings like these mix period details with modern bathrooms, and both need careful sealant work.

In bigger homes the problems are often about scale: long runs of kitchen worktop, large inset and standalone baths, twin basins, frameless glass screens and several showers, each with joints that age at different rates. We look at every one and tell you which need doing now and which can wait. Long worktop runs in stone or quartz also need a sealant that will not stain the edge, so we choose the product for the surface rather than using one tube for everything.

Apartments, glass and wooded plots

In converted mansions and newer apartment blocks, a leak from one shower can quickly reach the flat below, so prompt resealing protects neighbours as well as your own finishes. We can liaise with the building’s management for access and parking and keep shared areas clean.

Outside, many Sunningdale houses sit among mature trees. Shaded walls stay damp for longer, and leaf litter and moss collect on sills and thresholds, so external mastic around windows, bi-fold doors and orangeries can break down sooner than you would expect. We remove it fully, clean the surfaces and renew the joint with a flexible, weatherproof sealant in a colour that suits the frames.

Hotels, spas and the London Road shops

Sunningdale has hospitality on a bigger scale than most villages, with Coworth Park’s hotel and the spa at Charters. Spa areas, guest bathrooms and changing rooms need regular resealing without taking rooms out of use for long, which is where our sealant work for hotels fits in. We can work room by room and out of hours.

The shops on London Road have their own kitchens and washrooms, and property managers looking after apartments and rented houses can book us for a single unit or several at once.

Jobs we take on in Sunningdale

  • 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: Hotels, offices, washrooms and welfare areas resealed room by room, with out-of-hours working possible to arrange.
  • Remedial sealant & repairs: Leaks and lifting beads from earlier sealant jobs put right, starting with finding out why they failed.

  • Floor & skirting joints: Skirting-to-floor gaps, tiled floor movement joints and concrete floor joints sealed with the right product.
