Washroom sealing for commercial buildings in Fernhurst

We reseal washrooms and wet areas in offices, hotels, schools, universities, gyms, healthcare buildings and care homes, along with staff kitchens and tea points. The products and the method are chosen for how heavily each space is used. We work on kitchens and tea points, IPS panels and cubicles and accessible toilets and changing rooms, and the usual reasons a site gets in touch are failed sealant behind washroom basins and resealing that didn’t last because the old bead stayed. Most enquiries from Fernhurst start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Community buildings around smaller places like Fernhurst have kitchens and toilets used by many people. Fresh anti-mould sanitary silicone at sinks, worktops and toilets keeps them cleanable.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

Building owners, agents and FMs in Fernhurst

As a CHAS accredited contractor and Constructionline member, we’re straightforward to vet for your supplier list. We are fully insured, and our insurance certificate can go with the quote.

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

Our process

We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. Jobs in and around smaller places like Fernhurst are normally planned as a single visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  1. Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
  2. The phasing is agreed so there are always facilities open.
  3. The failed silicone is stripped and every face scraped clean of residue.
  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. You get a reopening time for every room, with signage left up until then.

Before we start on site

  • Tell staff and tenants when we will be in
  • Tell us your opening times and when work is allowed
  • Confirm the product named in the specification

Related advice

Leave it or put it right?

A tired washroom says a lot about how a building is run. Guests, clients, pupils and patients notice stained joints before they notice much else. Fresh sanitary silicone lifts a room with very little disruption. Halls, stores and units around places like Fernhurst may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

Why us?

  • A range of standard colours, depending on the product
  • Fully insured, including public liability cover
  • One number for every site we cover
  • Old sealant cut out, never sealed over

What the job involves on each surface

Healthcare and care settings

In healthcare, sealed joints are part of infection control. Your infection-control and estates rules are followed as well as site permits.

Showers and trays

Shower joints in hotels, gyms and workplaces work hard. Every joint is stripped, degreased, dried and given a new bead.

Questions about Fernhurst

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

Rarely all at once: work is phased so some facilities are always available. We’ll tell you the curing time for the product before we start.

Is Fernhurst off your patch?

Not at all. Fernhurst is within our area. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

Do you phase washroom resealing?

We phase it so there are always facilities open. We work through the building a room or section at a time. Tell us your site hours and access windows and we will plan around them.

Can you clean the mould off instead of resealing?

Usually not. The mould is inside the silicone, so it comes back however often it’s cleaned. Replacement is the lasting fix.

Do you work in hospitals, clinics and care homes?

We work in clinics, hospitals and care homes. Tell us what records you need and we will confirm with the quote before we start.

How long will the new sealant last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

Do you need to remove the old sealant?

We always remove it. New silicone won’t stick to the old so a bead over the top fails quickly.

What sets the cost

Each job is priced on its own details. The things that drive the figure:

  • How much there is to seal
  • Which sealant the job calls for
  • The site’s rules and procedures
  • Working within restricted access windows

The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

What we need to price the job

There’s no need for a formal survey. These details are enough to start:

  • A wide shot and a close-up of the area
  • Drawings or a marked-up plan, if available
  • Asbestos survey details if the building is older
  • The postcode of the building

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 send photos by email.

Wet areas in Fernhurst’s workplaces

Church halls and community buildings, such as those at The Parish Church of St Margaret, have kitchens and toilets used by many groups, and their sanitary sealant works hard. At a school such as Fernhurst Primary School, changing rooms and kitchens need cleanable joints as much as the toilets.

What we can’t put right

We check first that sealant really is the fix. It won’t put right:

  • Failed tanking beneath a wet-room floor or behind tiles
  • Mould caused by poor ventilation, which will return until the extract is fixed
  • Fittings that move too much to hold a bead

Not sure which it is? You can phone 01277 525 020 or email us and we will tell you honestly.
