Sealant jobs we do in Walton-on-Thames
Walton-on-Thames is a riverside town in Elmbridge with a long Thames frontage, a busy station and a lot of comfortable suburban housing. Mr Mastic covers Walton and neighbouring Hersham from our base in Crawley, renewing sealant around baths, showers, basins and worktops, and resealing windows, doors and outside joints.
It’s easy to put resealing off until the line has turned black, but sealant has a working life like anything else. Our guide to how long silicone sealant lasts explains what shortens it and when to replace it. When we do, we take the whole of the old bead out, clean and dry the joint, and lay a fresh line in a sealant suited to the room.
A railway town that kept growing
The railway shaped Walton. Between 1851 and 1911 the population rose from about 4,100 to more than 19,000, and many of the Victorian and Edwardian houses near the station and the town centre date from that time. Twentieth-century suburban roads then filled in around them. More recently, The Heart replaced the 1960s town centre with a shopping mall and 279 apartments overlooking Ashley Park.
The older houses often have bathrooms that have been refitted more than once, sometimes with new silicone run over old. That never holds, and mould grows in the layer between. Baths in these homes can also drop slightly when filled, which pulls a stiff bead away from the tiles. We cut out every layer and reseal with the bath full of water. Our bath resealing page covers the process.
South of the railway, Burwood Park in Hersham is a private estate laid out from the late 1920s on a former royal deer park, now with large detached houses and later infill homes. Bigger homes like these, and the apartments in town, bring walk-in showers, en-suites and sometimes wet rooms, where a sound seal at the floor and wall junctions is what stops water escaping. Our wet room sealing service is set up for exactly that.

Riverside weather by the Thames
The town sits low beside the Thames, and properties near the river and the open ground around it catch more wind and rain than the streets further back. Sun on south-facing elevations is just as hard on mastic, drying it until it cracks and lets water behind the frame. We use flexible, weatherproof sealant outside, add backing rod where gaps are deep and check thresholds and sills as well as the frame edges.
Offices by the station, shops and rented flats
Office headquarters cluster around Walton station, and the High Street, New Zealand Avenue and The Heart have a run of shops and restaurants. Staff washrooms, kitchens and customer toilets in places like these get constant use, and we can work out of hours so the business keeps running.
We also reseal for landlords and letting agents with flats in the town, usually between tenants, and for managing agents looking after shared buildings. If you have a list of properties, get in touch through our contact page and we’ll quote for them together.

Your questions about mastic work in Walton-on-Thames
Do you cover Hersham and Burwood Park as well as Walton?
Yes. We cover Walton-on-Thames, Hersham and the surrounding parts of Elmbridge.
I live in an apartment in The Heart. Can you reseal my shower?
Yes. We work in apartment buildings regularly and can tell you if anything needs agreeing with your managing agent first.
Why does my bath sealant keep splitting along the back edge?
Usually because the bath moves when it’s filled. We reseal with the bath full so the bead is laid at its lowest point and stays intact when it’s used.
Can you seal a wet room floor and walls?
Yes. We seal the junctions between floor and walls and around fittings with a flexible sanitary silicone suited to constant wetting.
Do you work for offices near the station?
Yes. We reseal washrooms, kitchens and showers in commercial buildings, and out-of-hours working can be arranged.
Will you take out the old silicone or seal over it?
We always take it out. New silicone doesn’t bond to old, so sealing over it fails quickly.
How soon can I use the bathroom afterwards?
Usually after around 24 hours. We’ll tell you the exact cure time for the sealant we use.
