Washroom sealing for businesses in Westdene

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Washroom sealing in Westdene

Not every silicone belongs in a washroom. Sanitary grades carry anti-mould additives, and neutral-cure versions avoid the damage acetoxy types can do to some metals, stone and mirror backings. In food areas, hygienic or food-safe sealants are used where food contact is possible. We work on showers, trays and wet room floors, vanity units and basins and accessible toilets and changing rooms, and the usual reasons a site gets in touch are sealant stained black around basins and showers and users noticing mouldy joints. A specialist sealant contractor works differently from a general builder: on jobs in Westdene, preparation and product choice get the time they need.

Pub and restaurant kitchens around smaller places like Westdene work hard on their joints. Smooth, sealed joints at worktops, sinks and wall cladding make cleaning easier, using a food-safe product near food preparation.

Work we carry out comes with a 12-month guarantee. Should something we installed fail, speak to us on 01277 525 020 or send details through our quote form and we will come back to it.

Diagnose, treat, sign off

Tell us your site hours and access windows and we will plan around them. While we are working, the area stays contained and tidy, and your contact hears from us before we move to the next area. Work in places the size of Westdene is planned as a single visit where we can. Clear photographs and measurements help us bring the right products.

  1. We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
  2. A phasing plan keeps part of the building’s facilities in use at all times.
  3. Failed silicone is removed completely and the surfaces cleaned of every trace.
  4. Joints are cleaned, degreased and dried before sealing.
  5. New sanitary silicone with anti-mould additives goes in and is tooled neat.
  6. You get a reopening time for every room, with signage left up until then.

Preparing the site

  • Let building users know which areas are affected
  • Confirm the product named in the specification
  • Tell us what induction or permit system the site runs

Getting a fixed quote

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

Maintenance after handover

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Brief cleaning staff to treat joints gently
  • Note failing joints building by building
  • Clear standing water from shower floors where possible
  • Report split joints at trays and basins early

We hand each area back once the silicone has had the cure time the product needs. We’ll tell you when the wet areas can be used, and it helps if signs stay up until then.

A split joint at a shower tray can leak for a long time before anyone sees it. At that stage, boards or ceilings may need repair, so reseal when you first spot a split.

When it isn’t the sealant

Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be any of the following:

  • Failed tanking beneath a wet-room floor or behind tiles
  • Panel boards already damaged by water
  • Loose panels, vanity units or tiles, which need fixing first

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

Wet areas in Westdene’s workplaces

The sea is no more than about 3 miles from Westdene, and coastal hotels, guest houses and holiday sites tend to fill up in the busy months. Heavy seasonal use is hard on shower and basin sealant, so resealing in the quieter months keeps rooms ready. Westdene has a number of hotels close by, all within 2 miles. Behind every hotel door there’s a bathroom whose sealant will need renewing sooner or later.

For a site such as Mill View Hospital, 1.7 miles to the south-west of Westdene, sanitary joints in clinical areas need sound, cleanable sealant and a careful method. At a retail site such as Goldstone Retail Park, 1.6 miles south of Westdene, public and staff toilets see heavy use, so mouldy or split sealant is best replaced in phases.

Westdene is about 2 miles north-east of Brighton and Hove, in Brighton and Hove. Anywhere in BN1, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Our Brighton and Hove coverage takes in 29 places, from busy centres to rural villages.

Work on washrooms and wet areas is covered throughout BN1 and BN3, for business premises of every kind. If your site is on Mill Road, Croft Road and London Road or close by, we can quote for washrooms and wet areas. Access to Westdene is via the A27 among other routes. Close to Westdene, our area also takes in Patcham (1 mile north-east), Withdean (1 mile south-east), Waterhall (1 mile north), Preston (1 mile south-east) and West Blatchington (1 mile south-west). Nearby towns on our patch include Carlton Hill (3 miles south-east), Hanover (3 miles south-east), Portslade (3 miles south-west), Kemptown (3 miles south-east), Whitehawk (3 miles south-east) and Bevendean (3 miles south-east).

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.

Showers and trays

In staff, hotel and changing-room showers, the tray joint and wall corners take the hardest use. Each bead is stripped, the joint dried and new sealant laid.

When to call us in Westdene

Panels and vanity units move slightly in use, and shower trays shift under foot. A bead that can’t cope with the movement splits along one edge.

Any of the following is a good reason to get the joints checked over:

  • Washrooms that look worn because of the sealant
  • Kitchen worktop joints that can’t be kept clean
  • Sealant laid over old silicone and now peeling
  • Open joints along basins and vanity units

Hotels such as Preston Park Hotel (to the south-east of Westdene) have en suite bathrooms where tired silicone at the bath, tray and basin is replaced room by room.

What your quote should include

  • Are they CHAS accredited or on Constructionline?
  • Can the work be phased to keep areas open?
  • What level of public liability insurance do they hold?
  • How they handle RAMS and site documents

Our contractor checklist

Why it’s worth doing now in Westdene

When a washroom looks worn, a refit isn’t the only answer. If the finishes are in good order, replacing the sealant may do much of what’s needed while bigger works are planned. Sealant hardens, cracks and loses grip with age, UV and movement. Renewing it in good time keeps the building weathertight.

The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.

What you get with us

  • Colour agreed before work starts
  • A Constructionline member, so easy to vet
  • Fully insured
  • Colours chosen to suit frames, cladding or finishes where possible

Westdene: questions and answers

Can work at a site such as University of Brighton Moulesecoomb Campus fit around teaching?

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 will confirm them alongside the quote.

Can work in a care setting near Westdene go ahead while residents are there?

Yes. Care settings are planned area by area, at times agreed with the home. Any site rules, from signing in to infection control, are agreed before we start.

Does weather matter for sealant work?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

What do you charge?

Every job gets its own fixed quote. For yours, call the office on 01277 525 020 or email a schedule or drawings.

Do you need to remove the old sealant?

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

How long does a typical visit take?

It depends on the scope, though a typical visit usually takes a few hours for one toilet block, with bigger buildings phased across a number of visits. Larger or phased jobs take longer, and we will give you a timescale with the quote.

Can you reseal washrooms in healthcare buildings?

Yes. Your infection-control rules, estates requirements and permits are followed. The work is phased around patients or residents.
