Sealant jobs we do in Addlestone

Addlestone is the largest settlement in Runnymede and the home of the borough’s Civic Centre, which opened on Station Road in 2008. The town centre has changed a great deal since then, with new apartments, a hotel and a cinema, while the streets around it run out to New Haw, Row Town and Woodham. Mr Mastic covers Addlestone from Crawley, with the M25 at junction 11 making it a straightforward trip.

Most of the calls we get are the everyday ones: a shower tray seal letting water through, black mould along the bath, a worktop joint that has shrunk, window mastic that has cracked. Each one gets the same treatment. The old sealant comes out completely, the joint is cleaned and treated, and a new bead goes on with a product chosen for that spot.

A regenerated town centre and a ring of suburbs

The clearest sign of change is Addlestone One, the regeneration scheme built by Bouygues Development beside the Civic Centre. Work began in 2015 and the scheme brought 213 apartments in two phases, along with a Premier Inn, a supermarket, shops, restaurants and a six-screen cinema. Further along Station Road, the Aviator Park business estate was completed in 2011, and some of its offices have since been converted into flats.

Beyond the centre, the housing is more varied. Row Town is a residential estate with its own shops, and the Ongar Hill parade serves the streets around it. New Haw, the southern part of the town, is mostly family housing that has filled in the ground towards Woodham. Census figures show a big privately rented sector in the Bourneside area and more socially rented homes in Addlestone North.

New apartments and office conversions often have compact shower rooms and builder-grade sealant that fails as the building settles. Our new build sealant snagging guide covers what to look for. In the older family houses, it is layered sealant from past refits and hardened mastic on replacement windows.

Apartment blocks, tenants and the flat below

With hundreds of flats in and around the centre, a lot of our Addlestone work is in blocks. In a flat, a failed shower seal is not just your problem: water can track under the tray and show up as a stain in the ceiling below long before you see anything in your own bathroom. We can arrange access and parking with managing agents, and bring everything up ourselves.

For rented homes, sealant is one of the first things to look tired at the end of a tenancy. We remove it fully, treat any mould and reseal so the property is ready for the next check-in. Out towards the Wey Navigation, houses near the water and trees can be damp, so anti-fungal silicone is a sensible choice in bathrooms there.

Station Road offices, the hotel and leisure units

The Addlestone One scheme brought a hotel, cinema and a run of restaurant and retail units to the town centre, and Station Road also has the Civic Centre and Aviator Park’s offices. Washrooms, staff kitchens and food preparation areas in places like these need sealant that is sound and easy to clean, and we can work out of hours to avoid disruption. Our commercial sealant page has more detail.

We also help letting agents and landlords across Runnymede with turnover resealing and mould complaints.

Sealant services across Addlestone

  • Bathroom & kitchen resealing: Mouldy or split sealant around baths, shower trays, basins and sinks removed completely and replaced with a neat, hygienic bead.
  • Window & door mastic: Window and door mastic that has dried out in the sun replaced with a weather-resistant joint that can move with the frame.

Addlestone: common questions

Do you cover all of Addlestone?

Yes. We cover the town centre and Station Road, Row Town, Ongar Hill, New Haw and Woodham, and nearby Chertsey.

I rent an apartment in Addlestone One and the shower sealant is mouldy. Can you reseal it?

Yes. We can work with your landlord or managing agent, remove the old sealant and reseal with anti-fungal silicone.

My flat was converted from offices. Why does the shower seal keep failing?

Conversions often have compact trays and walls that still move as the building settles. We remove the old sealant, check the tray is firm and use a flexible sanitary silicone.

Do you work for letting agents in Runnymede?

Yes. We reseal between tenancies and can quote for several properties together.

Can you work in a restaurant or hotel without closing it?

Yes. Early or late working can be arranged, and we seal areas in stages.

My bath sealant in New Haw has gone black again. Can it be stopped?

We take it right out, treat the mould underneath and use anti-fungal silicone; good ventilation helps it stay clean.

Can you replace the mastic round my uPVC windows?

Yes. We cut out the cracked mastic, clean the frame and brick, and apply a flexible exterior sealant.

I have just moved into a new-build flat in the town centre. When should the sealant be checked?

It is worth looking at it in the first year, because new buildings settle and builder sealant often splits. We can cut it out and reseal properly.
