Resealing and mastic work across Sunninghill
Sunninghill is a mainly residential village just east of Ascot, in the parish of Sunninghill and Ascot, with Sunningdale and Windsor Great Park close by. Many of its homes are large houses set in their own grounds, and those houses tend to have several bathrooms, a big kitchen and a lot of windows and doors. That adds up to a lot of sealant, and it all ages at slightly different rates.
Mr Mastic covers Sunninghill from our base in Crawley. A typical visit here might take in a family bathroom, an en suite, a cloakroom basin and the kitchen worktop, all in one day, so the house is put right in one go instead of piece by piece. If you are not sure how much life is left in what you have, our guide to how long silicone sealant lasts is a good place to start.
Houses in their own grounds around an old village centre
The village has a long history. St Michael and All Angels church was rebuilt in 1808 and again in 1826–27, and opposite it stands The Cedars, a Grade II listed house. In the centre, Cordes Hall was built in 1902 to designs by Edward and Joseph Morris, and a Methodist chapel opened in 1881 in a mission hall on The Terrace. Around this core, the village is characterised by generally large dwellings set in their own grounds, and the parish also takes in Cheapside and South Ascot.
Big houses bring their own sealant problems. Wet rooms and walk-in showers are popular, and a wet room depends entirely on its joints staying sound, because there is no tray to catch a leak. We reseal wall-to-floor and screen joints in wet rooms with care; see our wet room sealing page for what that involves.
Older houses that have been extended several times often have a different frame or render on each addition, and the joint where old meets new moves more than anywhere else. In kitchens, long runs of stone worktop and upstands need a fine, neat bead that does not distract from the material.
Listed neighbours, long drives and woodland settings
Near listed buildings such as The Cedars and around the old centre, owners are often careful about what goes on the outside of a house. We use neat, colour-appropriate sealant around frames and avoid smearing it onto brick or stone, so the joint does its job without drawing the eye.
Further out, houses sit among trees and gardens close to Windsor Great Park. Shaded, damp walls and leaf litter keep external joints wet for longer, and old mastic around frames, sills and doors can go green, crack and let rain in behind. We cut it out, clean the surfaces and renew the external joints with a flexible, weatherproof sealant suited to brick, render or timber.
Silwood Park, village shops and lettings
Silwood Park, first established as the manor house of Sunninghill in 1362, is now a campus of Imperial College London, and like any campus it has kitchens, washrooms and accommodation where sealant wears out with heavy use. Around the High Street, cafés, restaurants and shops have kitchens and customer toilets that need resealing from time to time, and we can work before opening or after closing.
We also help landlords and letting agents with houses and flats across the parish, resealing between tenancies so a property is ready for the next check-in.

Questions from Sunninghill
Do you cover all of Sunninghill?
Yes. We cover the whole village and the wider parish, including Cheapside and South Ascot, as well as neighbouring Ascot and Sunningdale.
Can you reseal several bathrooms in one visit?
Yes. In larger houses we often do a family bathroom, en suites and a cloakroom in a single day, so everything is finished together.
Our wet room has a damp patch outside the door. Could it be the sealant?
It often is. In a wet room the floor and wall joints are the main defence, so we inspect them and reseal any that have failed.
My house is near a listed building. Will the outside sealant look out of place?
We choose a colour that suits the brick, stone or frame and keep the bead neat, so it blends in rather than stands out.
The mastic around my back door has gone green. What can be done?
We cut it out, clean and dry the frame and brickwork, and apply a new weatherproof sealant that copes with damp, shaded walls.
Can you work around a busy household?
Yes. We tell you in advance which rooms we need and for how long, and how soon each one can be used again.
How long before I can use the bath?
Usually around 24 hours, depending on the product. We will tell you the cure time before we leave.
