Washroom sealing in High Cogges

Accessible toilets, shower rooms and changing rooms have joints that work harder than most: wet-floor edges, tray perimeters, basin tops and the line where flooring meets the wall. An open joint there lets water track under flooring or behind wall panels, so we look at them closely. We work on vanity units and basins, kitchens and tea points and urinals and WCs, and the failures we are asked to look at most are open joints at the base of cubicle panels and failed sealant in a tea point or staff kitchen. Looking for mastic applicators who cover High Cogges? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.

Smaller places such as High Cogges 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.

Work we carry out comes with a 12-month guarantee. If an installation problem shows up, give us a call on 01277 525 020 or email us and we will arrange a return visit.

Common questions from High Cogges clients

Do hotels near High Cogges have to close for sealant work?

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

Will you work in a care home in High Cogges without moving residents out?

Yes, with the manager deciding the order and timing of rooms. Tell us about any infection-control or safeguarding requirements and we’ll work to them.

Will you come and look before quoting?

That depends on the size and complexity of the job. Simple work can often be priced from photos, while larger or less clear jobs get a site visit first.

How long before the joints can be used?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.

Is there a guarantee on the work?

A 12-month guarantee covers the work. It covers our workmanship rather than damage, leaks from plumbing or ventilation problems.

What sealant do you use in washrooms?

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

How do you deal with asbestos in old sealant?

Managing asbestos is the dutyholder’s responsibility, so we will ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.

Surface by surface

Urinals and WC pans

Floor joints around WC pans are often forgotten. They are checked with everything else.

Wet-room floors and floor-to-wall joints

We seal the visible joints; we don’t install or repair waterproofing below and point it out if water appears to rise from below.

Why deal with it now?

A failed joint behind a basin or along a shower tray lets water run where it shouldn’t. That can lead to swollen boards, marked ceilings below and lingering smells which costs more to fix than a reseal. Halls, stores and units around places like High Cogges may not be checked every day, which gives a failed joint time to do damage. 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.

How a job runs

Where the site stays busy, 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. For work around High Cogges, we aim to finish in one 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. You get a fixed quote with the phasing plan.
  3. The whole of the old bead is removed.
  4. Joints are degreased and dried.
  5. New anti-mould sealant goes in and is tooled neat.
  6. Each area is handed back when ready.

What sealant work can’t fix

A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be one of these:

  • Condensation from failed extract fans
  • Leaking pipes, traps, wastes or cisterns, which need a plumber
  • Water escaping beneath the floor rather than through a joint

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 before you book.

Where we work in High Cogges

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

For managing agents and facilities managers

Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

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

General trades versus a specialist

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
