Washroom sealing for De Beauvoir Town sites

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Surface by surface

IPS and cubicle panels

Panel systems meet walls, floors and vanity tops at sealed joints. They stop water reaching the panel boards.

Showers and trays

A tray flexes every time it’s used and is constantly wet. Tray joints are where many washroom leaks start.

Washroom sealing in De Beauvoir Town

In a commercial washroom, sealant is usually the first thing to wear out. Around basins, urinals, cubicles, IPS panels and shower trays it takes water, soap, cleaning chemicals and knocks every day, and once mould grows into it, it can’t be scrubbed out. The fix is to remove it completely and reseal with sanitary silicone containing anti-mould additives. If you’re dealing with open joints at the base of cubicle panels and black mould inside silicone joints that cleaning can’t shift, we can help. A specialist sealant contractor works differently from a general builder: in De Beauvoir Town, that means joint design, primers and backing rod as standard.

Restaurants, cafés and hotel kitchens across London have joints at worktops, sinks and wall cladding that need to stay smooth and cleanable. Hygienic and anti-mould sanitary sealants are used where they suit, with food-safe products where food contact is possible.

Every job we finish is backed by a 12-month workmanship guarantee, in De Beauvoir Town as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Our process

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. In De Beauvoir Town, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.

  1. We agree which washrooms close and when.
  2. Anything behind the joints that needs another trade is flagged.
  3. Old sealant is stripped and the faces prepared.
  4. The right sanitary or food-safe sealant is applied.
  5. We give you a reopening time for every room.

Before we start on site

  • Tell us your opening times and when work is allowed
  • For older buildings, check the asbestos register before work
  • Make sure the joints can be reached

How the quote is worked out

Quotes vary with the job. It mainly depends on:

  • Removal of failed or old sealant
  • How much there is to seal
  • Location, for remote and island sites
  • Which sealant the job calls for

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

What we need to price the job

Good information means a firmer quote. Helpful details to send:

  • How the joints are reached, and at what height
  • Photos of the joints, close up and from further back
  • The site address and postcode
  • Drawings or a marked-up plan, if available

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To ask for one, give us a call on 01277 525 020 or send photos by email.

Do you need washroom sealing in De Beauvoir Town?

A lot of failed washroom sealant was laid over an old bead or a dirty surface. Silicone won’t adhere to a silicone bead so it peels away quickly.

Common reasons buildings call us in:

  • Complaints from staff, guests or users about tired washrooms
  • Sealant stained black around basins and showers
  • Failed sealant behind washroom basins
  • Resealing that didn’t last because the old bead stayed

For centre management at a site such as Anchor Retail Park, 2 miles south-east of De Beauvoir Town, washroom work is planned around footfall.

Questions to ask before you book

  • Will failed sealant be removed rather than covered?
  • Will RAMS and insurance details be available?
  • How the joint faces will be prepared and primed
  • Their approach to joint depth and backing

Choosing a commercial sealant contractor

When to bring in a specialist

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

What we can’t put right

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

  • Leaking pipes, traps, wastes or cisterns, which need a plumber
  • Swollen or delaminated boards behind panels or vanity tops
  • A room that stays damp because ventilation isn’t working

Not sure which it is? You can call 01277 525 020 or send photos by email and we will tell you honestly before you book.

What we seal

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

Questions we’re asked in De Beauvoir Town

Will you plan work around the academic year at somewhere like University of Wales Trinity Saint David London?

Yes. Education sites usually 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.

Will you work in a care home in De Beauvoir Town without moving residents out?

Yes. We work around residents’ routines, a room or two at a time. Tell us about any infection-control or safeguarding requirements and we’ll work to them.

When can the area be used after sealing?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.

How many days will you need on site?

We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.

Do you work in hospitals, clinics and care homes?

We do. We work to your estates and infection-control requirements and any site permits, and phase the work so areas keep facilities.

What about RAMS and site documents?

Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.

Is there a guarantee on the work?

Our workmanship has a 12-month guarantee, and we carry public liability insurance.
