Washroom sealing in Selmeston, done properly

Since 2005 we have resealed commercial washrooms for facilities teams, contractors and building owners. Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We are fully insured. Our workmanship is guaranteed for 12 months. We work on accessible toilets and changing rooms, IPS panels and cubicles and kitchens and tea points, and the usual reasons a site gets in touch are open joints at the base of cubicle panels and split or peeling sealant at shower trays. One point of contact handles commercial sealant work in Selmeston from the first photos to the final walk-round, whether it’s one building or several.

Community buildings around smaller places like Selmeston have kitchens and toilets used by many people. Fresh anti-mould sanitary silicone at sinks, worktops and toilets keeps them cleanable.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Washroom sealing around Selmeston: what changes locally

Central London is about 47 miles from Selmeston. Office toilets in the commuter belt are in use from first arrivals to last departures, so we phase work to keep some facilities open.

Office washrooms on sites such as Berwick Court Farm Business Park, 1.8 miles to the south-east of Selmeston, are in use all working day, so resealing is phased to keep some open. Healthcare estates like Chailey Heritage Marine Hospital, 5.3 miles south-west of Selmeston, expect contractors to follow their permits and cleaning rules in every washroom.

Selmeston is about 5 miles north of Seaford, in East Sussex. We send applicators to Selmeston for washrooms and wet areas, handled exactly as we handle every other area. Across East Sussex, 308 places are covered, Selmeston among them. We also cover Brighton, some 12 miles away.

What we can’t put right

We check first that sealant really is the fix. It isn’t the answer for:

  • A dripping waste or valve behind a panel
  • Vanity carcasses that have swollen
  • Condensation from failed extract fans

If in doubt, call 01277 525 020 or use the quote form and we will say what we think.

Surfaces we seal

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

Surface by surface

Kitchens and tea points

Kitchen joints need to be smooth and sealed so they can be cleaned properly. Food-safe sealants are used where food may touch the joint.

Showers and trays

Shower joints in hotels, gyms and workplaces work hard. Each bead is stripped, the joint dried and new sealant laid.

What affects the price in Selmeston

We price every job individually. The main factors are:

  • The product specified
  • Travel to remote or island sites
  • Any access equipment needed
  • Whether old sealant has to be cut out first

Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

What to include in your enquiry

Good information means a firmer quote. Helpful details to send:

  • Any specification or named product
  • Where the site is, with the postcode
  • Asbestos survey details if the building is older
  • The type of building and who uses it

For a fixed quote, call the office on 01277 525 020 or send photos by email, telling us the site location and the nature of the job. Our quote form is another easy route.

From enquiry to sign-off

On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, with the work itself usually taking between a morning and a week or so, set by the number of rooms and the phasing you need. Smaller jobs around Selmeston can be grouped with others nearby. A fixed quote is given before anything 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. The failed silicone is stripped and every face scraped clean of residue.
  4. Joints are cleaned, degreased and dried before sealing.
  5. We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
  6. Each room is handed back once the sealant has had its cure time.

Getting the site ready

  • Confirm the product named in the specification
  • Send asbestos survey details if the building is pre-2000
  • Warn occupants and staff about the work

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

FAQs: Selmeston

Will you plan work around the academic year at somewhere like University of Brighton?

Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.

Is Selmeston too far out for you?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Do you offer coloured sealant?

Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.

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

The failed bead is always removed. New silicone won’t stick to the old so a bead over the top fails quickly.

Are you insured?

Yes. We are fully insured, and the certificate can go with your quote.

What happens if old sealant might contain asbestos?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. 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 you follow the specification on our project?

Yes. Include it with the drawings when you ask for a quote, and we will price the work to it.

Signs you need washroom sealing in Selmeston

Panels and vanity units move slightly in use and trays shift slightly with each user. If the joint wasn’t laid to take that movement, it tears or peels away.

If one of these sounds familiar, it’s time for a closer look:

  • Split or peeling sealant at shower trays
  • Sealant laid over old silicone and now peeling
  • Urinal joints that look unhygienic
  • Washrooms that look worn because of the sealant

Student showers at universities like University of Brighton, 4.1 miles to the south-west of Selmeston, see more use than most, and their silicone shows it.

Before you book anyone

  • Will RAMS and insurance details be available?
  • How the joint faces will be prepared and primed
  • How long is the guarantee, and what does it include?
  • Their approach to joint depth and backing

How to choose a sealant contractor

When to bring in a specialist

For a quick touch-up, site staff may be fine, 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. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
