Washroom sealing for Shoreditch sites

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

When to call us in Shoreditch

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

Site and facilities staff are often the first to spot these:

  • Panel joints letting water behind
  • Washrooms that look worn because of the sealant
  • Black mould inside silicone joints that cleaning can’t shift
  • Shower tray joints that have opened up

Toilets at colleges like London College of Fashion (to the south-west of Shoreditch) take heavy use from students and staff alike.

Questions to ask before you book

  • Health and safety accreditation such as CHAS
  • How the existing material will be dealt with
  • The named product and why it was chosen
  • What level of public liability insurance do they hold?

Our contractor checklist

Washroom sealing for commercial buildings in Shoreditch

When mould has spotted a silicone joint, more cleaning won’t remove it. The mould has rooted into the silicone itself so it returns whatever the cleaning regime. Only replacement gets rid of it for good. Site teams most often ask us about urinal joints that look unhygienic and black mould inside silicone joints that cleaning can’t shift, on urinals and WCs, accessible toilets and changing rooms and vanity units and basins. One point of contact handles commercial sealant work in Shoreditch from the first photographs to the final walk-round, whether it’s one building or several.

In Shoreditch, as across London, commercial kitchens and washrooms need sealed joints that can be cleaned properly. 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 Shoreditch as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Leave it or put it right?

Running fresh silicone along a failed bead hides the problem briefly. It doesn’t bond, so it peels and traps dirt behind it. Full removal and proper cleaning is what makes the new joint last. In Shoreditch, each extra visit means more notices, permits and disruption, so a proper job first time, with the old sealant fully removed, is worth it.

There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.

Building owners, agents and FMs in Shoreditch

If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules.

What sealant work can’t fix

Being straight saves everyone time. New sealant won’t cure:

  • Vanity carcasses that have swollen
  • Water from plumbing, not from a joint
  • Water escaping beneath the floor rather than through a joint

If you’re not sure, just give us a call on 01277 525 020 or email a schedule or drawings and we will give you a straight answer.

What we seal

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

Surface by surface

Basins and vanity tops

Stone and some composite tops need a neutral-cure sealant and we choose a neutral-cure grade for them.

IPS and cubicle panels

Panel systems meet walls, floors and vanity tops at sealed joints. Those joints protect the boards behind from water.

Questions about Shoreditch

Can you work in a care home near Shoreditch with residents in?

Yes. Care settings are planned area by area, at times agreed with the home. Any site rules, from signing in to infection control, are agreed before we start.

Can you work around term dates at a campus such as Northumbria University London Campus?

Yes. We plan campus work around teaching, exams and residence turnarounds. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.

What if there’s asbestos in the old mastic?

Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.

Will cleaning remove black mould from sealant?

Surface cleaning won’t reach mould that has rooted into the bead. We replace the sealant with an anti-mould sanitary grade and point out if ventilation is part of the problem.

Who decides which product is used?

A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

How long will the new sealant last?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Can one quote cover more than one building?

Yes. A group of buildings can go on one quote, with one point of contact.

How a job runs

When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, and the work normally takes between a morning and a week or so, set by the number of rooms and the phasing you need. All of Greater London is in the ULEZ, and kerbside space in Shoreditch can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.

  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. 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.

What we need from you

  • Have the specification and drawings to hand
  • Move anything stored against the joints
  • Share the asbestos register for older buildings
