Washroom sealing for Tilgate sites

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

Our process

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. What matters most for a job in Tilgate is a clear list of what needs doing, so send photos of each area. You will then get a fixed price for the work.

  1. We agree which washrooms close and when.
  2. Anything behind the joints that needs another trade is flagged.
  3. Failed sealant and residue are stripped out.
  4. The right sanitary or food-safe sealant is applied.
  5. We give you a reopening time for every room.

Getting the site ready

  • Send asbestos survey details if the building is pre-2000
  • Move anything stored against the joints
  • Send any specification or drawings in advance

How we handle washroom sealing in Tilgate

Black spotting along a sealant bead is not a cleaning problem. The growth is inside the sealant so it returns whatever the cleaning regime. Only replacement gets rid of it for good. We work on accessible toilets and changing rooms, showers, trays and wet room floors and urinals and WCs, and the failures we’re asked to look at most are split or peeling sealant at shower trays and urinal joints that look unhygienic. A specialist sealant contractor works differently from a general builder: in Tilgate, that means joint design, primers and backing rod as standard.

Pub and restaurant kitchens around smaller places like Tilgate work hard on their joints. Sealed joints at sinks, worktops and splashbacks help keep the kitchen cleanable, using a food-safe product near food preparation.

We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Sanitary sealant for Tilgate buildings

The area within 2 miles of Tilgate holds plenty of hotels. Behind every hotel door there’s a bathroom whose sealant will need renewing sooner or later. We work a handful of rooms at a time, so the hotel keeps letting the rest. The 2 miles around Tilgate include three care or nursing homes. In care settings, wet rooms, assisted bathrooms and en suites rely on clean, sound sealant. Rooms are done a few at a time at times agreed with the home.

For a hotel such as Arora Hotel, 0.6 miles to the north-west of Tilgate, resealing en suites a few rooms at a time keeps the rest available. Staff changing rooms and patient toilets at places like Crawley Hospital, 1.2 miles north-west of Tilgate, need cleanable, sound silicone.

Tilgate is about 1 mile south-east of Crawley, in West Sussex. Across the RH10 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. 373 places across West Sussex fall within our area, including Tilgate.

Building owners, agents and FMs in Tilgate

If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Tilgate can sit alongside others in a wider programme.

Tilgate: questions and answers

Is Tilgate off your patch?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Will you work in a care home in Tilgate without moving residents out?

Yes. Care settings are planned area by area, at times agreed with the home. Tell us about any infection-control or safeguarding requirements and we’ll work to them.

What happens if old sealant might contain asbestos?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.

Can the sealant be colour-matched?

In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We will confirm the colours available for the specified product.

Are you insured?

Yes. Our insurance certificate can be sent alongside the quote.

What guarantee comes with washroom resealing?

A 12-month guarantee covers the work. It applies to our workmanship, not to plumbing leaks or damp from poor ventilation.

Do your applicators hold CSCS cards?

Yes. We use CSCS-carded applicators, as many construction sites ask for.

What sealant work can’t fix

Some faults sit outside our scope, and we point that out rather than sealing over them:

  • Hollow tiles or loose panels behind the joint
  • Water escaping beneath the floor rather than through a joint
  • A dripping waste or valve behind a panel

If you are not sure, just call the office on 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer.

What we seal

  • Kitchens and tea points
  • Accessible toilets and changing rooms
  • Showers, trays and wet room floors
  • Urinals and WCs
  • IPS panels and cubicles
  • Vanity units and basins

Common problems we fix in Tilgate

Washrooms are warm, damp and full of organic residue, and silicone joints hold onto all three. Anti-mould additives help, but in a poorly ventilated room mould can still take hold eventually.

It’s worth sending us details if you spot any of the following:

  • Sealant stained black around basins and showers
  • Failed joints along IPS and cubicle panels
  • Shower tray joints that have opened up
  • Stained or open joints at kitchen sinks and worktops

Customer toilets in retail centres such as County Mall (0.7 miles north-west of Tilgate) rarely close, so resealing is phased.

What to look for in a quote

  • What site paperwork they can supply
  • Who will actually carry out the work
  • Will failed sealant be removed rather than covered?
  • Whether primer will be used where the manufacturer specifies it

Choosing a commercial sealant contractor

General trades versus a specialist

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Why it’s worth doing now in Tilgate

A tired washroom says a lot about how a building is run. Visitors notice black sealant even when the room is otherwise spotless. Resealing is a modest task with a very visible payoff. In a smaller place such as Tilgate, getting a contractor back for a second visit takes time, so we’d suggest renewing all the joints that are going, not just the worst.

There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we’ll price your job on its own details.

What you get with us

  • One phone line for London, the South East and Scotland
