Work for main contractors and building owners

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We’re fully insured, and our insurance certificate can go with the quote.

Building owners and managing agents use us on sealant work across single buildings or whole portfolios around Mount Pleasant. Several sites can go on one quote, which keeps the paperwork simple.

Our process

On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, with the work itself normally taking between a morning and a week or so, set by the number of rooms and the phasing you need. Jobs in and around smaller places like Mount Pleasant are typically planned as a single visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  1. We inspect each washroom and record the joints to be resealed.
  2. The fixed quote sets out the rooms, the products and the phasing.
  3. The whole of the old bead is removed.
  4. Each joint is cleaned and left dry.
  5. New anti-mould sealant goes in and is tooled neat.
  6. Rooms reopen after the cure time.

Preparing the site

  • Flag any permit to work we will need
  • Send asbestos survey details if the building is pre-2000
  • Let building users know which areas are affected

Getting a fixed quote

Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.

Related advice

Looking after the joints

Regular inspection catches problems early. Specifically:

  • Don’t leave an open joint at a basin or tray
  • Clear standing water from shower floors where possible
  • Tell us about infection-control or permit rules before we quote
  • Inspect washroom sealant regularly

Add washroom sealant to routine inspections. Look for black spotting, cracks, peeling edges and gaps at the busiest fittings and log what you find.

In food areas, cleanability is something environmental health officers look at. Failed sealant around sinks and worktops is easy to put right in good time.

Why it’s worth doing now in Mount Pleasant

A tired-looking washroom doesn’t always need a refurbishment. If the finishes are in good order, replacing the sealant may do much of what’s needed while bigger works are planned. One visit to deal with every failing joint makes more sense than several trips to a place like Mount Pleasant, rather than one at a time. Photos of every joint help us quote for the whole job.

We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote and we will price your job on its own details.

Different surfaces, different methods

Changing rooms and gyms

Changing rooms in gyms and leisure centres stay wet and warm so sealant there works very hard. Anti-mould sanitary silicone is the standard choice.

Kitchens and tea points

Staff kitchens and tea points have joints at worktops, sinks and splashbacks. Sound joints keep those surfaces easy to clean.

When it isn’t the sealant

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

  • Mould caused by poor ventilation, which will return until the extract is fixed
  • Hollow tiles or loose panels behind the joint
  • Vanity carcasses that have swollen

If you are not sure, just give us a call on 01277 525 020 or email the details over and we will give you a straight answer.

Joints and surfaces we work on

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

Your questions answered

Will you plan work around the academic year at somewhere like University of Sussex?

Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Is Mount Pleasant too small for you to travel to?

Not at all. Mount Pleasant is within our area. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Can weather delay the job?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

What about RAMS and site documents?

Each site asks for different documents, so tell us what you need and we will confirm it when we quote.

How long does a job like this take?

The duration is planned around your programme and the access we are given. You will have an expected duration with the quote.

What do you charge?

Each job is quoted on its own details. For yours, phone 01277 525 020 or email us.

Can you follow the specification on our project?

Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it, flagging anything that needs clarifying.
