Washroom sealing for commercial buildings in Birchden

In a commercial washroom, sealant is typically the first thing to wear out. Basin tops, urinal backs, panel joints and shower trays put it under water, chemicals and daily cleaning, and once mould grows into it, it can’t be scrubbed out. We strip it out and lay new anti-mould sanitary silicone. We work on kitchens and tea points, vanity units and basins and showers, trays and wet room floors, and the usual reasons a site gets in touch are complaints from staff, guests or users about tired washrooms and failed sealant behind washroom basins. A single leaking joint is often how a building in Birchden first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Smaller places such as Birchden still have commercial washrooms and kitchens: in halls, pubs, schools, care homes and farm-based businesses. Mould gets into sealant in any washroom that doesn’t dry out, and once it’s in, the sealant is replaced.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Looking after the joints

For the best life from the joints:

  • Tell us about infection-control or permit rules before we quote
  • Add sealant joints to planned maintenance checks
  • Report faulty extraction promptly
  • Act on the first split you see at a shower tray

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 signage stays in place until that time.

Water getting behind IPS panels and vanity units can swell the boards. After that, those parts need replacing rather than resealing.

Commercial clients in Birchden

CHAS accredited and a Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

Quoting for work in Birchden

Sealant work doesn’t have a standard rate, because every site is different. What we take into account:

  • Phasing around occupants
  • Specialist products, such as fire-rated or hygienic sealants
  • Travel to remote or island sites
  • Induction, permit and paperwork requirements

Pricing washrooms and wet areas depends on how many there are, their condition and the access, plus any specification you’re working to. Call for a quote.

What we need to price the job

Whether it’s one area or a whole building, these details speed things up:

  • When you need the work done
  • A wide shot and a close-up of the area
  • The postcode of the building
  • Asbestos survey details if the building is older

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. For a chat about it beforehand, call the office on 01277 525 020 or email the details over.

On site: what to expect

At the end of each section, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. For work around Birchden, we aim to finish in one visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  1. Every room is surveyed and the failed joints listed.
  2. The fixed quote sets out the rooms, the products and the phasing.
  3. Old sealant is removed completely and the faces cleaned.
  4. Each joint is cleaned and left dry.
  5. A sanitary silicone bead is laid and given a smooth tooled finish.
  6. Rooms reopen after the cure time.

Getting the site ready

  • Send your site hours and access windows
  • Let us know about inductions and permits
  • Point out any areas we must not close

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. For smaller jobs, photos and a description will do.

Wet areas in Birchden’s workplaces

Birchden is about 30 miles from central London, in a commuter belt where offices and business parks are common. Business park offices have washrooms in daily use by staff, so we work a block of facilities at a time.

Student showers at universities like Canterbury Christ Church University - Salomons (3.8 miles north-east of Birchden) see more use than most, and their silicone shows it. Where you’re responsible for a hall attached to a building such as Church of St Thomas the Apostle, its kitchen and toilets need sealant that stays cleanable. At a school such as Groombridge St Thomas' Church of England Primary School, changing rooms and kitchens need cleanable joints as much as the toilets.

When it isn’t the sealant

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Leaks through tanking or membranes below the finishes
  • Hollow tiles or loose panels behind the joint
  • Condensation from failed extract fans

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

Where we work in Birchden

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

How the job changes by surface

Basins and vanity tops

Natural stone tops can be marked by acetoxy silicone, so the product is chosen to suit.

Kitchens and tea points

Kitchen joints need to be smooth and sealed so they can be cleaned properly. Where food contact is possible, we use a hygienic, food-safe sealant.

Questions about Birchden

Can you work on a hospital site such as Tunbridge Wells Homeopathic Hospital?

Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.

Is a smaller place like Birchden outside your area?

No. Places such as Birchden are covered as much as the big towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

How much does the work cost?

We don’t publish prices, because every site is different. Send photographs or drawings and we will price it at a fixed figure.

Can you send site paperwork?

Requirements differ from site to site, so tell us what you need and we’ll confirm it when we quote.

Do you hold CHAS accreditation?

Will cleaning remove black mould from sealant?

Surface cleaning won’t reach mould that has rooted into the bead. New anti-mould sanitary silicone is the treatment and point out if ventilation is part of the problem.

Will you come and look before quoting?

Many jobs can be quoted from photographs, drawings or a joint schedule. If the job needs a look first, we will arrange a visit.
