Washroom sealing in Whitwell, done properly

Accessible WCs, showers and changing areas have their own pinch points: shower trays, wet-room floor edges, basins and floor-to-wall junctions. Gaps in those places let water get under the floor or behind panels so they get particular attention. If you have sealant stained black around basins and showers and split or peeling sealant at shower trays, we can help, on kitchens and tea points, IPS panels and cubicles and showers, trays and wet room floors alike. A single leaking joint is often how a building in Whitwell first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Farm shops, cafés and venues in converted rural buildings around places like Whitwell have busy toilets and kitchens. We plan the work around bookings and opening times.

We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

What happens if it’s left?

Sealing on top of old silicone saves nothing. Silicone won’t grip silicone, so it lifts and holds moisture underneath. Cutting out completely and cleaning back takes a little longer and lasts. Older rural buildings around Whitwell move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

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

Commercial washrooms in Whitwell

With the shore within about 1 mile, Whitwell counts as a coastal location, and places by the sea often rely on visitors, so their hotels and holiday lets see heavy seasonal use. Bathrooms turned round daily in the busy months need sound, cleanable joints, so resealing in the quieter months keeps rooms ready.

Hotels such as St. Rhadagunds Hotel, 1.2 miles south-east of Whitwell, have en suite bathrooms where tired silicone at the bath, tray and basin is replaced room by room. Colleges such as St Catherine's College (3 miles east of Whitwell) have toilets, changing rooms and catering kitchens that can be resealed around term dates. Clinical washrooms at sites like Arthur Webster Memorial Hospital for Children, 4.5 miles north-east of Whitwell, are scheduled with the ward so the room is out of use for as little time as possible.

Whitwell is about 7 miles south of Newport, in the Isle of Wight. Any commercial site in Whitwell is covered, whether it’s a single job or part of a planned programme. We work across 125 places in the Isle of Wight, from busy centres to rural villages. We also cover Portsmouth, around 17 miles from Whitwell.

Work on washrooms and wet areas is covered throughout PO38, whatever the building. Among the streets we cover are High Street, Bannock Road and Nettlecombe Lane.

From enquiry to sign-off

Diagnose, treat, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. Rural sites near Whitwell may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.

  1. Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
  2. We agree which rooms close and when, so users always have somewhere to go.
  3. Failed silicone is removed completely and the surfaces cleaned of every trace.
  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.

Getting the site ready

  • Confirm the product named in the specification
  • Tell us what induction or permit system the site runs
  • Move anything stored against the joints

Related advice

Doing it in-house

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.

As a CHAS accredited contractor and Constructionline member, we’re straightforward to vet for your supplier list. We are fully insured, and our insurance certificate can go with the quote.

Questions about Whitwell

Can you work around term dates at a campus such as St Catherine's College?

Yes, holiday working periods are the norm on campus jobs. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Can you work on a hospital site such as Arthur Webster Memorial Hospital for Children?

Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Can you quote from photos?

Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit before quoting.

Is it possible to just clean mouldy silicone?

Cleaning may lighten it, but the mould returns. New anti-mould sanitary silicone is the treatment and point out if ventilation is part of the problem.

How do you choose the sealant?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

How soon can a washroom be used after resealing?

The silicone needs time to cure before water reaches it. Phasing is planned with the cure time in mind so there are always rooms open.

How do I request a quote?

You can use the quote form on this site; alternatively, call the office on 01277 525 020 or send details through our quote form. Include photos or drawings if you have them.

What affects the price in Whitwell

To price the job, we consider:

  • The size and state of each joint
  • The product specified
  • Removal of failed or old sealant
  • Phasing around occupants

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

What to include in your enquiry

Diagnosis starts before we arrive. Let us know:

  • Access details, including height
  • The type of building and who uses it
  • Where the site is, with the postcode
  • Clear photos of the problem areas

A handful of photographs and a postcode is the fastest way to a quote. Send them through the quote form, or call 01277 525 020 or email drawings and photos to discuss it first.

When something else is needed

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • Failed tanking beneath a wet-room floor or behind tiles
  • A dripping waste or valve behind a panel
  • A room that stays damp because ventilation isn’t working

Not sure which it is? You can phone 01277 525 020 or email us and we will tell you honestly before you book.

  • Kitchens and tea points
