Washroom sealing in Selsted

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Doing it in-house

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Washroom sealing for commercial buildings in Selsted

You can’t shut every toilet in an office, school or hotel at once. Work is phased by room or by section, so there are always facilities in use. Give us your site hours and access windows and the phasing is planned around them. Site teams most often ask us about panel joints letting water behind and mould spotting along silicone joints, on vanity units and basins, accessible toilets and changing rooms and urinals and WCs. For commercial sealant work in Selsted, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

In and around smaller places like Selsted, washroom work is often in halls, pubs, primary schools, care homes and holiday accommodation. Mould gets into sealant in any washroom that doesn’t dry out, and once it’s in, the sealant is replaced.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Common questions from Selsted clients

Is Selsted too small for you to travel to?

No. Places such as Selsted are covered as much as the big towns. London and every South East county are within our area. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Will the toilets in our Selsted building be out of use?

Not all at once. We take one block of facilities at a time. We will tell you the curing time for the product before we start.

Do you offer coloured sealant?

It depends on the product. Some ranges are wide, others limited, so the available colours are confirmed with the quote.

How long will the new sealant last?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

Do you phase washroom resealing?

The work is phased so users always have somewhere to go. One washroom, one bank of cubicles or one changing room is done at a time around your site hours and access windows.

Can you quote from photos?

Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.

Is it OK to put new silicone on top of the old?

We strip every bit of the failed bead and wipe away the residue first. It’s the difference between a joint that lasts and one that peels.

What the job involves on each surface

Urinals and WC pans

Urinal backs, troughs and slab joints are resealed with sanitary silicone once the whole of the old bead has gone.

Healthcare and care settings

Healthcare work is phased so wards, clinics or residents’ areas keep their facilities. Tell us what records you need and we will confirm with the quote.

Cost factors for washrooms and wet areas

What shapes the price:

  • Whether the work must be split into stages
  • The size and state of each joint
  • The product specified
  • Location, for remote and island sites

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we will explain how it’s made up.

Details that help us quote

However big the job, the same details help:

  • Clear photos of the problem areas
  • When you need the work done
  • Whether the building will be occupied during the work
  • Where the site is, with the postcode

Pricing a project or setting a maintenance budget? Send the scope and any drawings, and we will return a fixed quote that you can work with. If you have questions first, call 01277 525 020 or email the details over.

What we can’t put right

A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be any of the following:

  • Fittings that move too much to hold a bead
  • Leaks through tanking or membranes below the finishes
  • A room that stays damp because ventilation isn’t working

If in doubt, give us a call on 01277 525 020 or send details through our quote form and we’ll say what we think before you book.

Surfaces we seal

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

On site: what to expect

At the end of each section, 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. Jobs in and around smaller places like Selsted are typically planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. First, the phasing is agreed so facilities stay open.
  2. Leaks, loose panels or damp are pointed out first.
  3. Failed sealant and residue are stripped out.
  4. We reseal with the grade suited to each area.
  5. We confirm reopening times for each washroom.

Getting the site ready

  • Agree which areas must stay open
  • Tell staff and tenants when we’ll be in
  • Explain the parking and delivery arrangements

After the work

Problems stay small when the joints are checked regularly. In particular:

  • Leave signs up until the cure time is over
  • Act on the first split you see at a shower tray
  • Squeegee showers and trays after busy periods
  • Report faulty extraction promptly

Each room goes back into use only when the sealant has cured enough. You will be told when showers and basins can be used again, and it helps if signs stay up until then.

Mould in a joint spreads along the bead and into nearby grout and users notice. Dealing with it while it’s just the sealant keeps it simple.
