Mastic and sealant work in Horley

Mastic and sealant work in Horley

Horley sits just north of Gatwick Airport, with Crawley on the other side of the runway, so it is one of the closest towns to our Crawley base. Mr Mastic covers the whole of Horley, from the town centre and the streets around the station to Langshott, Meath Green and the new homes at The Acres and Westvale Park. We reseal baths, showers, basins and kitchen worktops, renew the mastic around windows and doors, and seal external joints that have started to let the weather in.

Being this close means short travel and easy scheduling, but the method never changes. Old sealant comes out completely, any mould behind it is treated, the joint is cleaned and dried, and a new bead goes on that suits the surface and the movement it has to cope with. A top-up line over failing silicone never holds, which is why we always start by taking the old bead out.

A railway town that doubled after 1950, and is still growing

The railway reached Horley in 1841, but the town grew slowly until around 1950. Since then its population has roughly doubled, and it has become a commuter town for London, Gatwick and Crawley. That history shows in the housing: older houses close to the station and High Street, then streets of post-war semis and terraces, then later estates. In the 2011 census, semi-detached homes were the largest group, with more than 3,100 of them, and there were also over 2,000 flats and apartments.

The biggest change since then has been in the north of the town. The North East Sector, known as The Acres, brought around 718 homes north of Langshott, built by Barratt David Wilson and Bovis. The North West Sector, Westvale Park, is planned for about 1,570 homes off Meath Green Lane, with building that began in 2015 by Crest Nicholson, A2Dominion, Taylor Wimpey and Persimmon. Smaller schemes, such as Coopers Lodge on Massetts Road and The Grange on Bonehurst Road, add more flats and houses around the town.

New homes settle in their first few years, and the builder’s sealant around showers, baths and kitchen worktops often splits as they do. Our new build mastic page explains what we look at. In the post-war houses, the usual jobs are tired bath seals, worktop joints that have shrunk back from the tiles and uPVC window mastic that has hardened and cracked.

Snagging lists, shared blocks and homes for older residents

A lot of Horley’s sealant work comes from snagging. Many buyers at The Acres and Westvale Park find gaps around the shower tray, cracked beads at the base of the bath or mastic that has pulled away from a window reveal within the first couple of years. If your developer’s warranty period has ended, or you’d rather have the job done properly once, we cut the sealant out and reseal it. Our guide to new build sealant snagging lists the joints worth checking.

In the flats around the town centre and on the new estates, a failed shower seal usually shows up first as a stain on the ceiling below. We can arrange access through a managing agent and park close to the block. For specialist housing for older people, such as Anvil Court at The Acres, we keep visits calm and tidy, and we explain cure times clearly so nobody uses a bath or shower too soon.

Gatwick hotels, business parks and the High Street

With Gatwick on the doorstep, Horley has a cluster of airport hotels whose bathrooms are used by a different guest almost every night. We reseal room by room so most of the building stays open, and out-of-hours working can be arranged. Our sealant work for hotels page explains how we plan it.

The town also has its own business parks and a long High Street of shops, cafés and offices, and Scotia Gas Networks is based in Horley. Staff kitchens, washrooms and shower rooms in buildings like these need resealing from time to time. Landlords and letting agents with flats near the station call us between tenancies, when a reseal can be left to cure before the next tenant moves in.

Horley: common questions

Do you cover all of Horley?

Yes. We cover the town centre, Langshott, Meath Green, The Acres and Westvale Park, along with Smallfield, Salfords and Charlwood nearby.

Are you based in Horley?

No. We’re based in Crawley, just the other side of Gatwick, so Horley is one of the closest towns we cover.

The shower sealant in my Westvale Park home has split. Is that unusual?

Not at all. New houses settle and showers get daily use, so builder sealant often fails early. We remove it fully and reseal; on a Forge Wood shower in Crawley we found exactly the same problem.

Can you reseal hotel bathrooms near Gatwick without closing the hotel?

Yes. We work room by room, and out-of-hours working can be arranged so guests are not disturbed.

Water is coming through my ceiling from the flat above. Could it be sealant?

Often it is a failed bath or shower seal upstairs. We can reseal it, though a leaking pipe needs a plumber first.

Do you replace mastic around uPVC windows on post-war houses?

Yes. We cut out hardened mastic, clean the frame and brickwork, and apply a flexible, weatherproof sealant in a colour to suit.

How soon can I use the shower after a reseal?

Usually after about 24 hours. We’ll tell you the cure time for the product we used before we leave.
