Washroom sealing across Westcott

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Our process

At the end of each section, we remove the tape, clean down and inspect every joint with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. Jobs in and around smaller places like Westcott are typically planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. Every room is surveyed and the failed joints listed.
  2. You get a fixed quote with the phasing plan.
  3. The whole of the old bead is removed.
  4. Joints are degreased and dried.
  5. A sanitary silicone bead is laid and given a smooth tooled finish.
  6. Each area is handed back when ready.

Preparing the site

  • For older buildings, check the asbestos register before work
  • Tell us what induction or permit system the site runs
  • Explain the parking and delivery arrangements

Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Washroom sealing for commercial buildings in Westcott

Closing all the facilities in a building isn’t an option. We phase the work one washroom, one bank of cubicles or one changing room at a time, so there are always facilities in use. Tell us your site hours and access windows and we will plan around them. Most enquiries involve shower tray joints that have opened up and mould spotting along silicone joints, on urinals and WCs, IPS panels and cubicles and kitchens and tea points. For commercial sealant work in Westcott, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

In and around smaller places like Westcott, washroom work is often in halls, pubs, primary schools, care homes and holiday accommodation. Sealant that has gone black with mould normally can’t be cleaned, so it is cut out and replaced.

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

Surface by surface

Wet-room floors and floor-to-wall joints

We seal the visible joints; we don’t install or repair waterproofing below and point it out if water appears to rise from below.

Showers and trays

In staff, hotel and changing-room showers, the tray joint and wall corners take the hardest use. Every joint is stripped, degreased, dried and given a new bead.

Busy facilities in and around Westcott

A 2-mile radius around Westcott takes in a number of hotels. En suite bathrooms, staff changing rooms and kitchens all need their sanitary silicone renewed in time. We work a handful of rooms at a time, so the hotel keeps letting the rest. There are four care or nursing homes within about 2 miles of Westcott. Assisted bathrooms and wet rooms in care settings need sanitary sealant that stays cleanable. We plan the work with the manager so residents are disturbed as little as possible.

On a healthcare site such as Dorking Community Hospital, 1.4 miles east of Westcott, washroom work starts with the infection-control team’s sign-off. For a school such as Surrey Hills All Saints Primary School, washroom and kitchen sealant can be renewed around term dates.

Westcott is about 2 miles west of Dorking, in Surrey. Any commercial site in Westcott is covered, whether it’s a single job or part of a planned programme. Westcott is one of 379 places in Surrey on our list. There’s a separate page for London, roughly 22 miles from Westcott.

What we’re called out for in Westcott

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

What tends to prompt an enquiry:

  • Failed sealant in a tea point or staff kitchen
  • Open joints at the base of cubicle panels
  • Urinal joints that look unhygienic
  • Sealant laid over old silicone and now peeling

For a hotel such as The Bell Hotel, 1.4 miles east of Westcott, resealing en suites a few rooms at a time keeps the rest available.

What your quote should include

  • How the existing material will be dealt with
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Who will actually carry out the work
  • Which product they’ll use, and why it suits the joint

Choosing a commercial sealant contractor

Quoting for work in Westcott

Each job is priced on its own details. The main factors are:

  • Removal of failed or old sealant
  • Site requirements such as inductions and permits
  • How much there is to seal
  • How accessible the joints are

A quote for washrooms and wet areas depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.

Sending details for a quote

The more we know, the firmer the quote. When you get in touch, include:

  • The product your specification calls for
  • The asbestos register, for older buildings
  • How the joints are reached, and at what height
  • Your programme or deadline

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. The easiest way is to ring 01277 525 020 or email a schedule or drawings.

Owners, agents and contractors

If you look after buildings for someone else, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.

Building owners and managing agents use us on sealant work across single buildings or whole portfolios around Westcott. Several sites can go on one quote, which keeps the paperwork simple.

When something else is needed

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

  • Hollow tiles or loose panels behind the joint
  • A room that stays damp because ventilation isn’t working
  • Water from plumbing, not from a joint

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

Where we work in Westcott

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

Your questions answered

Would you work within a site like Dorking Community Hospital?

Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.

Do hotels near Westcott have to close for sealant work?

Rarely, if ever. We take a few rooms out at a time. The plan is built around your bookings.

Will you quote for a small job?

Small jobs are welcome alongside larger packages. Photos and a description are enough to start.

Do you cover Westcott?

Yes. We cover Westcott, within our coverage of Greater London, South East England and Scotland. For a quote, call 01277 525 020 or send photos by email.

What do you charge?

There isn’t a price list, as every site differs. Send photographs or drawings and we will price it at a fixed figure.

How long will the new sealant last?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

How long before the toilets can reopen?

Each sealant has a cure time before it should get wet. We plan the phasing around that so facilities are never short.
