Washroom sealing for Wych Cross sites

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Washroom sealing in Wych Cross, done properly

When mould has spotted a silicone joint, more cleaning won’t remove it. The mould has rooted into the silicone itself so it returns whatever the cleaning regime. Only replacement gets rid of it for good. If you’re dealing with stained or open joints at kitchen sinks and worktops and discoloured joints around urinals and WC pans, we can put it right, whatever the surface. For commercial sealant work in Wych Cross, you deal with one contact from quote to sign-off, whether it’s one building or several.

Smaller places such as Wych Cross still have commercial washrooms and kitchens: in halls, pubs, schools, care homes and farm-based businesses. Mould gets into sealant in any washroom that doesn’t dry out, and once it’s in, the sealant is replaced.

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Questions we are asked in Wych Cross

Is a hospital such as Queen Victoria Hospital somewhere you can work?

Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.

Is a smaller place like Wych Cross outside your area?

No. Places such as Wych Cross are covered as much as the big towns. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.

Is it OK to put new silicone on top of the old?

The whole of the old bead is removed and the surfaces cleaned first. That’s what makes the new joint last.

Which sealant will you use?

The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Can one quote cover more than one building?

Yes. Several buildings can share a single quote, and you deal with one contact throughout.

Can you reseal washrooms in healthcare buildings?

We work in clinics, hospitals and care homes. Tell us what records you need and we will confirm with the quote.

What happens if old sealant might contain asbestos?

The duty to manage asbestos sits with the building’s dutyholder, so we will ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.

Our process

In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed before we move to the next. If others near Wych Cross need work, visits can be combined, which keeps travel down. You will have a fixed quote before work starts.

  1. Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
  2. The phasing is agreed so there are always facilities open.
  3. We strip out the old bead and clean off the residue left behind.
  4. We clean and dry every surface so the new sealant can grip.
  5. New sanitary silicone with anti-mould additives goes in and is tooled neat.
  6. Rooms reopen after the product’s cure time, and we move to the next.

Preparing the site

  • Arrange parking or a loading space
  • Send your site hours and access windows
  • Let building users know which areas are affected

Wet areas in Wych Cross’s workplaces

Wych Cross is about 30 miles from central London. Business park offices have washrooms in daily use by staff, and resealing in phases keeps facilities available.

Clinical washrooms at sites like Queen Victoria Hospital (to the north of Wych Cross) are scheduled with the ward so the room is out of use for as little time as possible. Schools such as Greenfields School have toilets, changing rooms and kitchens that are best resealed in the holidays. Office washrooms on sites such as Forest Row Business Park, 2 miles north of Wych Cross, are in use all working day, so resealing is phased to keep some open.

Wych Cross is about 4 miles south-east of East Grinstead, in East Sussex. Across the RH18 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Wych Cross is one of 308 places in East Sussex on our list for washrooms and wet areas. There’s a separate page for Brighton, about 18 miles away.

If you need washroom sealing in RH18, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee.

We also cover Chelwood Gate (1 mile south), Forest Row (2 miles north), Birchgrove (2 miles south-west), Coleman's Hatch (2 miles north-east) and Chelwood Common (2 miles south).

General trades versus a specialist

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Why deal with it now?

Washrooms shape how visitors judge a building. Visitors notice black sealant even when the room is otherwise spotless. Resealing is a modest task with a very visible payoff. One visit to deal with every failing joint makes more sense than several trips to a place like Wych Cross. Send photographs of each area and we will quote for the lot.

We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote.
