Washroom sealing in Well Street

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Washroom sealing in Well Street

Closing all the facilities in a building isn’t an option. We phase the work one washroom, one bank of cubicles or one changing room at a time, so there are always facilities in use. Give us your site hours and access windows and the phasing is planned around them. We work on urinals and WCs, kitchens and tea points and showers, trays and wet room floors, and the usual reasons a site gets in touch are panel joints letting water behind and complaints from staff, guests or users about tired washrooms. Searching for sealant specialists in Well Street? We’ve been sealing commercial buildings since 2005.

Smaller places such as Well Street 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.

Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Should maintenance staff do it?

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Surface by surface

Kitchens and tea points

In commercial kitchens, smooth, cleanable joints help keep the kitchen hygienic. Where food contact is possible, we use a hygienic, food-safe sealant.

IPS and cubicle panels

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

Well Street: questions and answers

Could you schedule work at a campus like University for the Creative Arts - Maidstone for the vacation?

Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Do you take on work at healthcare sites like Maidstone 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.

Can you work to our specification?

Yes. The specification and the manufacturer’s installation guidance are what we work to.

What do you charge?

It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote.

Is Well Street in your area?

Yes. Well Street is in our area. To discuss a job, call the office on 01277 525 020 or use the quote form.

Do you need to remove the old sealant?

We always remove it. Fresh silicone can’t key to an old bead so a bead over the top fails quickly.

What about RAMS and site documents?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.

On site: what to expect

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. If others near Well Street need work, visits can be combined. A fixed quote is given before anything starts.

  1. We survey each room, count the joints and note anything behind them that needs another trade.
  2. A phasing plan keeps part of the building’s facilities in use at all times.
  3. Failed silicone is removed completely and the surfaces cleaned of every trace.
  4. We clean and dry every surface so the new sealant can grip.
  5. A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
  6. Each room is handed back once the sealant has had its cure time.

Preparing the site

  • Clear stock, furniture or equipment away from the joints
  • Share the asbestos register for older buildings
  • Tell us your opening times and when work is allowed

Getting a fixed quote

Why deal with it now?

Water gets behind panels and under floors through a failed joint. That can lead to swollen boards, marked ceilings below and lingering smells, and fixing that takes far more work than resealing. Halls, stores and units around places like Well Street may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

What you get with us

  • Over 20 years of commercial sealing
  • Fully insured, including public liability cover
  • Colours chosen to suit frames, cladding or finishes where possible
  • Constructionline member for supplier checks

Washroom sealing around Well Street: what changes locally

The area within 2 miles of Well Street holds several hotels. Behind every hotel door there’s a bathroom whose sealant will need renewing sooner or later. The work can go floor by floor, agreed with housekeeping. Well Street is about 27 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 phase work to keep some facilities open.

If you manage an office at a site such as Kings Hill Business Park, 1.5 miles south-west of Well Street, the washrooms and tea points can be done a floor at a time. Church halls and community buildings, such as those at Church of St James, have kitchens and toilets used by many groups, and their sanitary sealant works hard.

Signs you need washroom sealing in Well Street

Commercial cleaning is harder on sealant than everyday use. Strong chemicals, scourers and jet washing roughen, discolour or lift a bead so grime sticks to the damaged surface.

It’s worth sending us details if you spot any of the following:

  • Kitchen worktop joints that can’t be kept clean
  • Complaints from staff, guests or users about tired washrooms
  • Resealing that didn’t last because the old bead stayed
  • Sealant stained black around basins and showers

Student showers at universities like University for the Creative Arts - Maidstone, 3.2 miles east of Well Street, see more use than most, and their silicone shows it.
