Washroom sealing in Broadwater, done properly

In a busy washroom, the sealant normally gives up long before the tiles or fittings. Basin tops, urinal backs, panel joints and shower trays put it under water, chemicals and daily cleaning, and once mould grows into it, it can’t be scrubbed out. We strip it out and lay new anti-mould sanitary silicone. Site teams most often ask us about stained sealant around pans and urinals and sealant lifting along a tray edge, on urinals and WCs, accessible toilets and changing rooms and kitchens and tea points. Most enquiries from Broadwater start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

A place of Broadwater’s size will typically have a few buildings with commercial washrooms: a school, a surgery, a pub or café, perhaps a care home. However small, each needs the old sealant removed completely and anti-mould sanitary silicone applied to clean, dry joints.

We stand by our work: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

Washroom sealing in Broadwater: the local picture

Broadwater sits close to the coast, within about 2 miles, and places by the sea often rely on visitors, so their hotels and holiday lets see heavy seasonal use. Washrooms used guest after guest wear their sanitary silicone faster, so resealing in the quieter months keeps rooms ready. Central London is about 48 miles from Broadwater. Office washrooms on business parks see heavy weekday use, so we work a block of facilities at a time.

Church halls and community buildings, such as those at St. Mary's Church, have kitchens and toilets used by many groups, and their sanitary sealant works hard. Hotels such as The Railway Hotel (to the south of Broadwater) have en suite bathrooms where tired silicone at the bath, tray and basin is replaced room by room. Colleges such as Northbrook College (under half a mile south of Broadwater) have toilets, changing rooms and catering kitchens that can be resealed around term dates.

Broadwater is about 1 mile east of Worthing, in West Sussex. Across the BN14 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Our West Sussex coverage takes in 373 places. We also cover Brighton, some 11 miles away.

Business premises anywhere in BN14 and BN11 are within our area. Streets here include Forest Road, Turner Road and Langton Road. Nearby places we also cover include Offington (1 mile north-west), Worthing (1 mile west), Salvington (1 mile north-west), East Worthing (1 mile south-east) and Sompting (2 miles east) for washrooms and wet areas. Bigger towns within reach include Bognor Regis (14 miles west), Burgess Hill (14 miles north-east), Littlehampton (7 miles west), Shoreham-by-Sea (5 miles east), Rustington (6 miles west) and Storrington (7 miles north-west).

How a job runs

Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed before the next one starts. For a job in Broadwater, the main thing is a clear picture of the work. A fixed quote follows.

  1. We survey each room, count the joints and note anything behind them that needs another trade.
  2. We agree which rooms close and when, so users always have somewhere to go.
  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.

What sealant work can’t fix

We check first that sealant really is the fix. It won’t put right:

  • Loose panels, vanity units or tiles, which need fixing first
  • Leaks through tanking or membranes below the finishes
  • Swollen or delaminated boards behind panels or vanity tops

If you are not sure, just phone 01277 525 020 or email a schedule or drawings and we will give you a straight answer before you book.

What we seal

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

Maintenance after handover

Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:

  • Leave signs up until the cure time is over
  • Photograph and log failed joints across the estate
  • Inspect washroom sealant regularly
  • Don’t leave an open joint at a basin or tray

Each room goes back into use only when the sealant has cured enough. We’ll tell you when the wet areas can be used and signage stays in place until that time.

Boards behind panels and vanity tops can swell when water gets past a failed joint. Once that happens, a reseal won’t fix them.

FAQs: Broadwater

Is hospital work, at somewhere like Worthing Hospital, something you do?

Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.

Could you schedule work at a campus like Northbrook College for the vacation?

Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

How do I request a quote?

The quote form is the simplest route, though you can also call 01277 525 020 or send photos by email. Photos, drawings or a joint schedule help us quote quickly.

Are your applicators CSCS-carded?

Yes. Our applicators hold CSCS cards, which many sites require.

Is any job too small?

We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.

Do you work in Broadwater?

Yes. We take on work across Broadwater, with one number for every area we cover.

Can the sealant be colour-matched?

That depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.

Why act early in Broadwater

Gaps and mould in joints give dirt and bacteria somewhere to sit, and in kitchens, clinics and schools that is a real concern. Sound, smooth joints are much easier to keep clean. Over time, UV, weather and movement wear any sealant out. Replacing it before it fails keeps water out.

What a job costs comes down to how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a quote once you have the details.

What you get with us

  • Colours chosen to suit frames, cladding or finishes where possible

Healthcare and care settings

We phase washroom sealing so care areas are never left without facilities. Records you need can be confirmed with the quote.

IPS and cubicle panels

A panel that has already swollen won’t be fixed by sealant and we will point out any we see.

Owners, agents and contractors

For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first.

If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.
