Washroom sealing for Cold Brayfield sites

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

After the work

For the best life from the joints:

  • Include joints in routine washroom inspections
  • Keep washrooms out of use until we say the sealant has cured
  • Don’t leave trays and floors sitting wet
  • Mention any site permits or estates rules at quote stage

Each room goes back into use only when the sealant has cured enough. We’ll tell you when the wet areas can be used, and it helps if signs stay up until then.

Mouldy sealant only gets harder to ignore, and complaints follow. Replacing it early keeps the job to a reseal.

Washroom sealing in Cold Brayfield, done properly

Not every silicone belongs in a washroom. Sanitary grades carry anti-mould additives, and neutral-cure versions avoid the damage acetoxy types can do to some metals, stone and mirror backings. Where food contact is possible, we use a hygienic, food-safe grade. Most enquiries involve panel joints letting water behind and black mould inside silicone joints that cleaning can’t shift, on kitchens and tea points, vanity units and basins and accessible toilets and changing rooms. Looking for mastic applicators who cover Cold Brayfield? We’ve been sealing commercial buildings since 2005.

Smaller places such as Cold Brayfield still have commercial washrooms and kitchens: in halls, pubs, schools, care homes and farm-based businesses. Sealant that has gone black with mould normally can’t be cleaned, so it is cut out and replaced.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Our process

Before we leave any area, we remove the tape, clean down and inspect every joint. Where the sealant needs time to cure before use, we tell you and sign the area. For work around Cold Brayfield, we aim to finish in one visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.

  1. We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
  2. The phasing is agreed so there are always facilities open.
  3. Failed silicone is removed completely and the surfaces cleaned of every trace.
  4. Joints are cleaned, degreased and dried before sealing.
  5. A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
  6. Rooms reopen after the product’s cure time, and we move to the next.

Preparing the site

  • Clear stock, furniture or equipment away from the joints
  • Tell us what induction or permit system the site runs
  • Agree which areas must stay open

Request a quote

Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

Advice

What the job involves on each surface

Healthcare and care settings

Assisted bathrooms and accessible toilets get heavy use, so their joints often need renewing sooner.

Wet-room floors and floor-to-wall joints

Changing rooms and accessible showers often have wet floors, so their perimeter joints get close attention.

What we can’t put right

Some faults sit outside our scope, and we say so rather than covering them up:

  • Panel boards already damaged by water
  • Leaks through tanking or membranes below the finishes
  • Fittings that move too much to hold a bead

If in doubt, ring 01277 525 020 or send photos by email and we will say what we think before you book.

What we seal

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

Cold Brayfield: questions and answers

Is Cold Brayfield off your patch?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Which documents can you supply for work in Cold Brayfield?

RAMS, insurance certificate, CSCS details: list what the site needs and we will confirm it with the quote. We’re CHAS accredited and a Constructionline member, with £5m public liability insurance and CSCS-carded applicators.

How do we ask for a quote?

The quote form is the simplest route, though you can also phone 01277 525 020 or email the details over. Photos, drawings or a joint schedule help us quote quickly.

Do you take on multi-site work?

Yes. A group of buildings can go on one quote, and you deal with one contact throughout across South East England, Greater London and Scotland.

Will all the toilets be closed at once?

Only the area we’re working in is closed. Rooms go back into use once the sealant has cured and we start the next.

When can showers be used after new sealant?

The silicone needs time to cure before water reaches it. We plan the phasing around that so facilities are never short.

Do you work to architects’ specifications?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.

How the quote is worked out

We price every job individually. The things that drive the figure:

  • Backing rod, priming and other preparation
  • Removal of failed or old sealant
  • The total length or number of joints
  • Site requirements such as inductions and permits

The price depends on the quantity of joints, how much old material needs removing and the access. Call for a quote when you are ready.

What we need to price the job

Diagnosis starts before we arrive. Let us know:

  • Specification clauses that apply
  • Drawings or a marked-up plan, if available
  • Anything awkward about access or site hours
  • The type of building and who uses it

Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, speak to us on 01277 525 020 or email drawings and photos.

When to call us in Cold Brayfield

Low-level joints get hit by mop buckets, cleaning trolleys and feet at skirting lines, urinal bases and around pans.

Any of the following is a good reason to get the joints checked over:

  • Panel joints letting water behind
  • Complaints from staff, guests or users about tired washrooms
  • Shower tray joints that have opened up
  • Failed sealant in a tea point or staff kitchen

Schools such as Newton Blossomville Church of England School have toilets, changing rooms and kitchens that are best resealed in the holidays.

Questions to ask before you book

  • Is the sealant right for the movement and the substrate?
  • Their plan for phasing and protecting the area
  • How joint depth will be controlled
  • How the existing material will be dealt with

Questions to ask before you appoint anyone
