Washroom sealing near Clifton

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Aftercare for building managers

Problems stay small when the joints are checked regularly. Specifically:

  • Keep washrooms out of use until we say the sealant has cured
  • Report split joints at trays and basins early
  • Keep a record of which washrooms need attention
  • Include joints in routine washroom inspections

Ask your cleaning team to use gentle products and soft cloths on sealant. Aggressive descalers, solvents and scouring pads shorten its life and give mould a start.

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.

Washroom sealing in Clifton, done properly

Facilities managers, contractors and building owners have used us for washroom sealing for over 20 years. We are CHAS accredited and a Constructionline member, with CSCS-carded applicators. We are fully insured. Our workmanship is guaranteed for 12 months. We work on vanity units and basins, urinals and WCs and showers, trays and wet room floors, and what we’re called in for most is sealant laid over old silicone and now peeling and stained sealant around pans and urinals. A specialist sealant contractor works differently from a general builder: in Clifton, that means joint design, primers and backing rod as standard.

Smaller places such as Clifton 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.

We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Diagnose, treat, sign off

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 before the next one starts. For work around Clifton, we aim to finish in one visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. We agree which washrooms close and when.
  2. Anything behind the joints that needs another trade is flagged.
  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.

Getting the site ready

  • Clear stock, furniture or equipment away from the joints
  • Tell staff and tenants when we will be in
  • Flag any permit to work we will need

Related advice

Surface by surface

Basins and vanity tops

Basin joints get wet every time someone washes their hands, so the wall joint and bowl surrounds tend to fail before anything else. They are resealed with anti-mould sanitary silicone.

Urinals and WC pans

Urinal backs, troughs and slab joints are resealed with sanitary silicone after the old bead and residue are removed.

Clifton: questions and answers

Would you work within a site like Horton General Hospital?

Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.

Does a hotel in Clifton need to shut while its sealant is renewed?

Rarely, if ever. We take a few rooms out at a time. Tell us your quiet periods and access windows and we will plan around them.

Which silicone is right for commercial washrooms?

It depends on the joint. Washrooms and showers take anti-mould sanitary silicone while kitchens may need a food-safe grade.

Can you work to our specification?

Yes. We follow the specification, along with the manufacturer’s installation guidance.

Do you have public liability insurance?

Yes. We are fully insured, and the certificate can go with your quote.

Do you work in Clifton?

Yes. Clifton is in our area and the rest of Oxfordshire. For a quote, speak to us on 01277 525 020 or email a schedule or drawings.

When can showers be used after new sealant?

Cure times vary by product and temperature. You will get a reopening time for each area before we leave it.

Why it’s worth doing now in Clifton

Cleaning mouldy sealant only masks it, but the mould is rooted in the silicone and comes back. A full reseal deals with it and cleaners stop fighting a losing battle. Halls, stores and units around places like Clifton may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.

Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Why us?

  • Standard and matched colours in many product ranges
  • One number for every site we cover
  • Workmanship guaranteed for 12 months
  • A Constructionline member, so easy to vet

How the quote is worked out

What shapes the price:

  • Specialist products, such as fire-rated or hygienic sealants
  • Whether old sealant has to be cut out first
  • Whether the work must be split into stages
  • The total length or number of joints

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.

What we need to price the job

However big the job, the same details help:

  • Drawings or a marked-up plan, if available
  • The postcode of the building
  • A wide shot and a close-up of the area
  • The type of building and who uses it
