Washroom sealing in Clapper Hill, done properly

In a busy washroom, the sealant typically gives up long before the tiles or fittings. Around basins, urinals, cubicles, IPS panels and shower trays it takes water, soap, cleaning chemicals and knocks every day, and once mould grows into it, it can’t be scrubbed out. The fix is to remove it completely and reseal with sanitary silicone containing anti-mould additives. If you have urinal joints that look unhygienic and sealant lifting along a tray edge, we can help, whatever the surface. Searching for sealant specialists in Clapper Hill? We’ve been sealing commercial buildings since 2005.

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

Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Questions about Clapper Hill

Will the toilets in our Clapper Hill building be out of use?

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

Is Clapper Hill off your patch?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Do you take on small jobs?

Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.

Can you work to our specification?

Yes. Include it with the drawings when you ask for a quote, and we will price the work to it, flagging anything that needs clarifying.

Do you guarantee washroom sealing?

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

What do you charge?

Each job is quoted on its own details. For yours, ring 01277 525 020 or email the details over with a description of the work.

How long does a typical visit take?

That varies with the scale of the job, but the work typically takes half a day to a day per washroom, depending on the number of fittings. Larger or phased jobs take longer, and we will give you a timescale with the quote.

What the job involves on each surface

Basins and vanity tops

Water getting past a vanity top joint can swell the board beneath. Resealing early protects the unit.

Changing rooms and gyms

We phase work so not every changing area is closed at once. Tell us your site hours and access windows and we’ll plan around them.

What we are called out for in Clapper Hill

Cubicle panels, IPS panels and vanity units flex when people lean on them or doors are slammed and trays shift slightly with each user. If the joint wasn’t laid to take that movement, it tears or peels away.

It’s worth sending us details if you spot any of the following:

  • Complaints from staff, guests or users about tired washrooms
  • Sealant laid over old silicone and now peeling
  • Failed sealant in a tea point or staff kitchen
  • Panel joints letting water behind

For buildings on a site such as Business Park, which lies south-east of Clapper Hill, washrooms and tea points can be resealed in phases through the working week.

Questions to ask before you book

  • Whether old or failed sealant will be cut out, not overlaid
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Health and safety accreditation such as CHAS
  • How long is the guarantee, and what does it include?

Choosing a commercial sealant contractor

Work for main contractors and building owners

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Clapper Hill can form part of a wider programme across Kent.

How a job runs

At the end of each section, the masking comes off, the area is cleaned and every joint is checked. Where the sealant needs time to cure before use, we tell you and sign the area. Rural sites near Clapper Hill may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.

  1. We survey each room, count the joints and note anything behind them that needs another trade.
  2. A phasing plan keeps part of the building’s facilities in use at all times.
  3. The failed silicone is stripped and every face scraped clean of residue.
  4. Joints are cleaned, degreased and dried before sealing.
  5. New sanitary silicone with anti-mould additives goes in and is tooled neat.
  6. You get a reopening time for every room, with signage left up until then.

What we need from you

  • Share your working hours and any access restrictions
  • Agree which areas must stay open
  • Let us know about inductions and permits

Honest limits

Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is one of these:

  • Leaks through tanking or membranes below the finishes
  • A dripping waste or valve behind a panel
  • Vanity carcasses that have swollen

If in doubt, speak to us on 01277 525 020 or send photos by email and we’ll say what we think.

Joints and surfaces we work on

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

Why deal with it now?

Gaps and mould in joints give dirt and bacteria somewhere to sit, and in kitchens, clinics and schools that is a real concern. A smooth, sealed joint can be cleaned properly. One visit to deal with every failing joint makes more sense than several trips to a place like Clapper Hill, rather than one at a time. Photos of every joint help us quote for the whole job.

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

  • CSCS-carded applicators
