About our washroom sealing in Capel

Our washroom work covers offices, hotels, schools and colleges, leisure centres and gyms, clinics and care homes, plus the kitchens and tea points that go with them. Product and method follow how hard each area is used and cleaned. We work on showers, trays and wet room floors, IPS panels and cubicles and accessible toilets and changing rooms, and the failures we are asked to look at most are panel joints letting water behind and split or peeling sealant at shower trays. Most enquiries from Capel start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

Halls and community buildings near places like Capel are used by different groups through the week, and their toilets and kitchens show it. 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 the quote explains what it covers.

Common problems we fix in Capel

We often find acrylic caulk or general-purpose sealant in joints that should have sanitary silicone. They aren’t made for constant wetting, and they stain, crack or wash out.

Common reasons buildings call us in:

  • Panel joints letting water behind
  • Kitchen worktop joints that can’t be kept clean
  • Stained sealant around pans and urinals
  • Open joints along basins and vanity units

Student showers at universities like University of Kent - Tonbridge, 3.4 miles to the west of Capel, see more use than most, and their silicone shows it.

What to look for in a quote

  • Is the sealant right for the movement and the substrate?
  • Whether their applicators hold CSCS cards
  • How joint depth will be controlled
  • Do they follow the manufacturer’s priming guidance?

Questions to ask before you appoint anyone

Keeping the joints sound

Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Keep washrooms out of use until we say the sealant has cured
  • Report faulty extraction promptly
  • Act on the first split you see at a shower tray
  • Keep a record of which washrooms need attention

Mild cleaning products and non-abrasive cloths look after sanitary silicone best. Aggressive descalers, solvents and scouring pads shorten its life over 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.

What the job involves on each surface

Urinals and WC pans

Urinal backs, troughs and slab joints are resealed with sanitary silicone once the whole of the old bead has gone.

IPS and cubicle panels

Swollen or delaminated boards need replacing and we will point out any we see.

Why it’s worth doing now in Capel

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. Halls, stores and units around places like Capel may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.

No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

For a school such as Capel Primary School, washroom and kitchen sealant can be renewed around term dates. Where you are responsible for a hall attached to a building such as Church of St Thomas à Becket, its kitchen and toilets need sealant that stays cleanable.

Common questions from Capel clients

Could you schedule work at a campus like University of Kent - Tonbridge for the vacation?

Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.

Is a hospital such as Tunbridge Wells Hospital at Pembury somewhere you can work?

Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Will you quote for a small job?

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

What happens if old sealant might contain asbestos?

The duty to manage asbestos sits with the building’s dutyholder, so we will ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.

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.

Will you come and look before quoting?

That depends on the size and complexity of the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.

Do you phase washroom resealing?

Just the room being resealed is out of use. Each room reopens after the sealant’s cure time and we start the next.

From enquiry to sign-off

Site rules come first: signing in, inductions and any permit to work. Once we’re cleared to begin, we take the joints in the sequence agreed with you. Smaller jobs around Capel can be grouped with others nearby, which keeps travel down. You will have a fixed quote before work starts.

  1. We inspect each washroom and record the joints to be resealed.
