Sealant jobs we do in Weybridge
Weybridge grew up where the River Wey meets the Thames. Mr Mastic, based in Crawley, covers the whole town, including Oatlands and St George’s Hill, for bathroom and kitchen resealing, window and door mastic and external joints.
Black spots in silicone are the usual reason people call. Once mould has grown into a bead, cleaning won’t shift it, because it lives inside the sealant. The only lasting answer is to cut it all out, treat and dry the joint and reseal with an anti-fungal silicone. Our anti-mould resealing page sets out how we go about it.
Private estates, Victorian growth and plenty of flats
The town expanded after the railway station opened in 1838, and many Victorian and Edwardian houses date from the decades that followed. In 1911 the builder W. G. Tarrant bought around 936 acres to create St George’s Hill, with covenants setting a minimum plot of one acre. It remains an area of large detached houses, often with several bathrooms, steam showers, big kitchens and expanses of glass.
The 2011 census shows the other side of Weybridge too: its northern and southern wards are dominated by flats and apartments. Compact bathrooms there, often with no window, hold moisture for longer, so the sealant needs to be anti-fungal and the room needs ventilating well. In flats, a failing shower seal can quickly become a neighbour’s problem as well as yours.
Larger homes bring glazing work: bi-fold and sliding doors, roof lanterns, orangeries and frameless shower screens. The joints around these need a sealant that will cope with sun, movement and the weight of large panes. Our glazing sealant page covers the types of glazing we seal.

Two rivers and low-lying ground
With the Thames on one side and the Wey and its navigation running through, parts of the town are low-lying and exposed to damp and weather. South-facing glazing on bigger homes takes plenty of sun as well, and old mastic around frames and doors dries, shrinks and lets rain behind it. We use flexible, weatherproof sealants outside with backing rod where needed, so the new joint can move without splitting.
Hotels, Brooklands offices and schools
Weybridge has a number of hotels and venues, including the Oatlands Park Hotel, set in a mansion that became a hotel in 1856. Hotel bathrooms get daily use and need to look spotless, and our sealant contractor work for hotels is planned room by room so you keep letting the rest.
Aircraft building at Brooklands carried on until 1988, and the former factory land now holds offices, light industry and retail, alongside Brooklands Museum and Mercedes-Benz World. The town also has schools and Brooklands College. Staff showers, washrooms and kitchens in buildings like these see heavy daily use, and a failed seal there is a hygiene issue as well as an untidy one. We reseal them with anti-bacterial sanitary silicone, with out-of-hours working available so the facilities are ready when people arrive.

Towns near Weybridge
Weybridge: common questions
Do you work on St George’s Hill?
Yes. We cover St George’s Hill, Oatlands and the rest of Weybridge, and can arrange access with you in advance on private roads.
Can you reseal around bi-fold doors and roof lanterns?
Yes, where they can be reached safely. We remove the old sealant and use a weatherproof product suited to the frame and the glass.
The silicone around my frameless shower screen has gone black. Can it be cleaned?
Not once mould has grown into it. We cut the old sealant out, treat the joint and reseal with anti-fungal silicone.
Do you work for hotels in the area?
Yes. We reseal hotel bathrooms room by room, and out-of-hours working can be arranged.
I have a flat in the town centre with no bathroom window. What can I do about mould?
Use the extractor fan during and after showers, dry the seal and keep the door open afterwards. If the silicone is already mouldy, it needs replacing.
How long will new sealant last?
It depends on use and care, but properly prepared and well looked-after sealant lasts far longer than a bead laid over old silicone. Every job comes with our one-year guarantee.
