Washroom sealing for Ashlett sites

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Questions we are asked in Ashlett

Will all the washrooms in our Ashlett building be closed at once?

Not all at once. We take one block of facilities at a time. We’ll tell you the curing time for the product before we start.

Is a hospital such as Coldeast somewhere you can work?

Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.

Do you do washroom sealing in healthcare settings?

Yes. We work to your estates and infection-control requirements and any site permits, and phase the work so areas keep facilities.

How many days will you need on site?

We plan the time on site around your programme and access. You will have an expected duration with the quote.

Do you work in Ashlett?

Yes. Sites across Ashlett are covered.

Can weather delay the job?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

Is it possible to just clean mouldy silicone?

Cleaning may lighten it, but the mould returns. We replace the sealant with an anti-mould sanitary grade and point out if ventilation is part of the problem.

About our washroom sealing in Ashlett

Our washroom work covers offices, hotels, schools and colleges, leisure centres and gyms, clinics 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 urinals and WCs, IPS panels and cubicles and vanity units and basins, and the failures we are asked to look at most are complaints from staff, guests or users about tired washrooms and discoloured joints around urinals and WC pans. A specialist sealant contractor works differently from a general builder: on jobs in Ashlett, preparation and product choice get the time they need.

Halls and community buildings near places like Ashlett are used by different groups through the week, and their toilets and kitchens show it. Resealing sinks, worktops and WCs with anti-mould silicone keeps them clean and watertight.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

For managing agents and facilities managers

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.

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, plus a 12-month guarantee.

Common problems we fix in Ashlett

Much of the failed sealant we remove was applied over old silicone or residue. New silicone won’t grip the old, so it soon lets go.

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

  • Complaints from staff, guests or users about tired washrooms
  • Failed sealant behind washroom basins
  • Discoloured joints around urinals and WC pans
  • Failed joints along IPS and cubicle panels

Halls linked to places like Church of All Saints host groups all week, which is hard on kitchen and toilet sealant.

Questions to ask before you book

  • How long is the guarantee, and what does it include?
  • Health and safety accreditation such as CHAS
  • How the existing material will be dealt with
  • What level of public liability insurance do they hold?

Questions to ask before you appoint anyone

Leave it or put it right?

Washrooms shape how visitors judge a building. Guests, clients, pupils and patients notice stained joints even when the room is otherwise spotless. Fresh sanitary silicone lifts a room with very little disruption. Older rural buildings around Ashlett move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

The product called for affects the cost, and so does the preparation. Access, phasing and site rules also count.

Why appoint us

  • Coloured sealants to suit the setting, where available
  • One number for every site we cover
  • Fully insured, including public liability cover
  • Our applicators hold CSCS cards

On site: what to expect

Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. Smaller jobs around Ashlett can be grouped with others nearby, which keeps travel down. You will have a fixed quote before work starts.

  1. Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
  2. A phasing plan keeps part of the building’s facilities in use at all times.
  3. Failed silicone is removed completely and the surfaces cleaned of every trace.
  4. We clean and dry every surface so the new sealant can grip.
  5. We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
  6. You get a reopening time for every room, with signage left up until then.

Getting the site ready

  • Have the specification and drawings to hand
  • Send asbestos survey details if the building is pre-2000
  • Make sure the joints can be reached

Surface by surface

Urinals and WC pans

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

Showers and trays

A tray flexes every time it’s used and is constantly wet. Tray joints are where many washroom leaks start.

Sanitary sealant for Ashlett buildings

Ashlett sits close to the coast, within about 1 mile, and seaside hospitality normally has a peak season that works washrooms hard. Showers and en suites in constant use are where silicone moulds and splits first, so we plan the work for quieter weeks where possible.

Office washrooms on sites such as Ensign Way Business Park, 2.2 miles north of Ashlett, are in use all working day, so resealing is phased to keep some open. At a hotel such as Falcon Hotel, which lies west of Ashlett, the quieter weeks are the time to reseal bathrooms.

Ashlett is about 4 miles south-east of Hythe, in Hampshire. Commercial clients in Ashlett use us for work on washrooms and wet areas. We work across 723 places in Hampshire. Southampton is covered too, around 7 miles from Ashlett.

Maintenance after handover

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Include joints in routine washroom inspections
  • Don’t leave trays and floors sitting wet
  • Make sure washroom ventilation is running
  • Note failing joints building by building

Include sealant joints in your planned maintenance checks. Look for black spotting, cracks, peeling edges and gaps at the busiest fittings and photograph anything new.

Boards behind panels and vanity tops can swell when water gets past a failed joint. After that, those parts need replacing rather than resealing.
