Washroom sealing in Chavey Down, done properly

When mould has spotted a silicone joint, more cleaning won’t remove it. The growth is inside the sealant so it returns whatever the cleaning regime. Only replacement gets rid of it for good. If you are dealing with kitchen worktop joints that can’t be kept clean and sealant laid over old silicone and now peeling, we can help. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Chavey Down it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Smaller places such as Chavey Down still have commercial washrooms and kitchens: in halls, pubs, schools, care homes and farm-based businesses. Sealant that has gone black with mould typically can’t be cleaned, so it is cut out and replaced.

We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant.

How a job runs

In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then handed back before the next one starts. Jobs in and around smaller places like Chavey Down are normally planned as a single visit, so photos and measurements up front really help. That way the right products come on the day.

  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. The right sanitary or food-safe sealant is applied.
  5. We confirm reopening times for each washroom.

What we need from you

  • Have the specification and drawings to hand
  • Arrange parking or a loading space
  • For older buildings, check the asbestos register before work

Common problems we fix in Chavey Down

Low-level joints get hit by mop buckets, cleaning trolleys and feet, especially at floor edges and around urinals and WC pans.

Site and facilities staff are often the first to spot these:

  • Failed sealant behind washroom basins
  • Shower tray joints that have opened up
  • Complaints from staff, guests or users about tired washrooms
  • Sealant laid over old silicone and now peeling

Where you’re responsible for a hall attached to a building such as St Martin's Church, its kitchen and toilets need sealant that stays cleanable.

What to look for in a quote

  • The terms of the workmanship guarantee
  • Whether their applicators hold CSCS cards
  • Whether primer will be used where the manufacturer specifies it
  • Which product they’ll use, and why it suits the joint

How to choose a sealant contractor

How the job changes by surface

Basins and vanity tops

Basin joints get wet every time someone washes their hands, so the joint to the wall and around each bowl fails early. We remove the old bead and lay a fresh one of sanitary silicone.

Healthcare and care settings

In healthcare, sealed joints are part of infection control. We work to your estates and infection-control requirements and any permits the site uses.

Looking after the joints

For the best life from the joints:

  • Clean sealant with gentle products and a soft cloth
  • Add sealant joints to planned maintenance checks
  • Tell us about infection-control or permit rules before we quote
  • Keep a record of which washrooms need attention

Keep extract fans working and vents clear. A room that stays damp will grow mould on almost anything, so get faulty extract looked at.

Small numbers of failed joints are quick to phase in. Left until every washroom is affected, it becomes a bigger programme with more phasing to plan.

Your questions answered

Do you take on work at healthcare sites like Heatherwood Hospital?

Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.

Can you work around term dates at a campus such as Imperial College Silwood Park Campus?

Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Let us know which documents your site asks for, and we will confirm them alongside the quote.

What sealant do you use in washrooms?

Sanitary silicone with anti-mould additives in most cases. Neutral-cure grades are used where acetoxy types could mark metals, stone or mirror backings.

Are you CHAS accredited and on Constructionline?

Yes. We are CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.

Can the sealant be colour-matched?

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

What will the job cost?

There isn’t a price list, as every site differs. Send photographs or drawings and we’ll price it at a fixed figure.

Is it possible to just clean mouldy silicone?

Not for long. Mould grows into the sealant itself, so it comes back however often it’s cleaned. Replacement is the lasting fix.

Commercial clients in Chavey Down

If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Chavey Down can form part of a wider programme across Bracknell Forest.

What happens if it’s left?

When a washroom looks worn, a refit isn’t the only answer. Where tiles, panels and fittings are sound, new sealant may be enough to put it right for now. One visit to deal with every failing joint makes more sense than several trips to a place like Chavey Down, rather than one at a time. Photos of every joint help us quote for the whole job.

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.
