About our washroom sealing in Shalstone

Accessible toilets, shower rooms and changing rooms have joints that work harder than most: wet-floor edges, tray perimeters, basin tops and the line where flooring meets the wall. An open joint there lets water track under flooring or behind wall panels so they get particular attention. Most enquiries involve users noticing mouldy joints and panel joints letting water behind, on kitchens and tea points, IPS panels and cubicles and urinals and WCs. Whoever orders the work in Shalstone, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.

Smaller places such as Shalstone still have commercial washrooms and kitchens: in halls, pubs, schools, care homes and farm-based businesses. Mould gets into sealant in any washroom that doesn’t dry out, and once it’s in, the sealant is replaced.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Common problems we fix in Shalstone

Daily commercial cleaning wears sealant faster than people expect. Harsh products, abrasive pads and pressure washing break down a joint’s surface and edges, and dirt and mould then get a foothold.

Things that usually lead to an enquiry:

  • Stained sealant around pans and urinals
  • Panel joints letting water behind
  • Failed sealant behind washroom basins
  • Sealant lifting along a tray edge

Where you’re responsible for a hall attached to a building such as Church of St Edward, its kitchen and toilets need sealant that stays cleanable.

Questions to ask before you book

  • Proof of insurance
  • Will failed sealant be removed rather than covered?
  • The named product and why it was chosen
  • How joint depth will be controlled

Questions to ask before you appoint anyone

Questions we are asked in Shalstone

Is Shalstone off your patch?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.

Could you schedule work at a campus like University of Buckingham for the vacation?

Yes. Education sites normally 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.

What if there’s asbestos in the old mastic?

The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.

How much does the work cost?

It depends on the job: quantities, access, the product and any phasing. Call for a fixed quote.

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.

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.

Do you do washroom sealing in healthcare settings?

We work in clinics, hospitals and care homes. Any records you need are confirmed with the quote before we start.

From enquiry to sign-off

We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact. Rural sites near Shalstone 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 room is surveyed and the failed joints listed.
  2. The fixed quote sets out the rooms, the products and the phasing.
  3. The whole of the old bead is removed.
  4. Each joint is cleaned and left dry.
  5. New anti-mould sealant goes in and is tooled neat.
  6. Rooms reopen after the cure time.

Preparing the site

  • Warn occupants and staff about the work
  • Explain the parking and delivery arrangements
  • Point out any areas we must not close

Request a quote

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.

Different surfaces, different methods

Wet-room floors and floor-to-wall joints

Changing rooms and accessible showers often have wet floors so the edges are checked carefully.

Healthcare and care settings

Accessible and assisted washrooms are used and cleaned intensively, so their joints often need renewing sooner.

What sets the cost

Your fixed quote is built from the real scope. It takes account of:

  • Travel to remote or island sites
  • Phasing around occupants
  • Any access equipment needed
  • Site requirements such as inductions and permits

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Before you send an enquiry

However big the job, the same details help:

  • What the building is and how it’s used
  • When you need the work done
  • A wide shot and a close-up of the area
  • Asbestos survey details if the building is older

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to give us a call on 01277 525 020 or email the details over with what you know.

Leave it or put it right?

Bleaching black sealant may lighten it for a few days but the growth is inside the bead and returns. Replacement deals with the cause in the joint and your cleaning team stops chasing it. Around Shalstone, it’s better to renew all the failing joints at once. Send photos of each area and we’ll quote for the lot.

There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote.
