Washroom sealing in The Stocks, done properly

Accessible WCs, showers and changing areas have their own pinch points: wet-floor edges, tray perimeters, basin tops and the line where flooring meets the wall. Gaps in those places let water get under the floor or behind panels, so we look at them closely. Most enquiries involve shower tray joints that have opened up and kitchen worktop joints that can’t be kept clean, on kitchens and tea points, showers, trays and wet room floors and vanity units and basins. Facilities teams, main contractors and managing agents in The Stocks tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Rural businesses near smaller places such as The Stocks, from cafés to event venues, rely on washrooms and kitchens that stay clean. Tell us your opening times and quiet periods and we will plan around them.

We stand by our work: 12 months, guaranteed. That covers our preparation and application.

What happens if it’s left?

Bleaching black sealant may lighten it for a few days but the growth is inside the bead and returns. Replacement deals with the cause in the joint and cleaners stop fighting a losing battle. One visit to deal with every failing joint makes more sense than several trips to a place like The Stocks, rather than one at a time. Photos of every joint help us quote for the whole job.

What a job costs comes down to the quantity of joints, what has to come out first and how the joints are reached. Call for a quote when you’re ready.

Why us?

  • A range of standard colours, depending on the product
  • Matching to RAL references, product permitting
  • Our applicators hold CSCS cards
  • Commercial sealant work since 2005

From enquiry to sign-off

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. For a building around The Stocks, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

  1. We survey each room, count the joints and note anything behind them that needs another trade.
  2. The phasing is agreed so there are always facilities open.
  3. We strip out the old bead and clean off the residue left behind.
  4. Joints are cleaned, degreased and dried before sealing.
  5. New sanitary silicone with anti-mould additives goes in and is tooled neat.
  6. Rooms reopen after the product’s cure time, and we move to the next.

What we need from you

  • Make sure the joints can be reached
  • Arrange parking or a loading space
  • Point out any areas we must not close

Site staff or a sealant specialist?

Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Keeping The Stocks washrooms open while we work

The Stocks lies roughly 49 miles out from central London. Washrooms in commuter-belt offices take constant weekday traffic, and resealing in phases keeps facilities available.

Where you’re responsible for a hall attached to a building such as Parish Church of St John the Baptist, its kitchen and toilets need sealant that stays cleanable.

The Stocks is about 11 miles south-west of Ashford, in Kent. Commercial clients in The Stocks can call on us for washrooms and wet areas. Our Kent coverage takes in 931 places. We also cover Brighton, around 39 miles from The Stocks.

After the work

After handover, a little attention goes a long way:

  • Clear standing water from shower floors where possible
  • Share your site rules when you send details
  • Report split joints at trays and basins early
  • Note failing joints building by building

Add washroom sealant to routine inspections. Check for mould spots, splits, lifting edges and open joints at trays, basins and urinals and photograph anything new.

Inspectors look at whether kitchen surfaces can be kept clean. Failed sealant around sinks and worktops is easy to put right in good time.

Different surfaces, different methods

Kitchens and tea points

Kitchen joints need to be smooth and sealed so they can be cleaned properly. Food-safe sealants are used where food may touch the joint.

Showers and trays

In staff, hotel and changing-room showers, the tray joint and wall corners take the hardest use. Each bead is stripped, the joint dried and new sealant laid.

Questions about The Stocks

What documents will you need to give us for a job in The Stocks?

We’ll confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. We’re CHAS accredited and a Constructionline member, with £5m public liability insurance and CSCS-carded applicators.

Will the toilets in our The Stocks building be out of use?

Not all at once. We take one block of facilities at a time. Each area is handed back once the sealant has cured enough to use.

Who decides which product is used?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Are your applicators CSCS-carded?

Yes. Our applicators hold CSCS cards, which many sites require.

How long will the new sealant last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

How long does a typical visit take?

It depends on the scope, but the work typically takes between a morning and a week or so, set by the number of rooms and the phasing you need. Larger or phased jobs take longer, and we will give you a timescale with the quote.

Do you need to see the site first?

It depends on the job. Straightforward work can often be priced from photos and measurements, and bigger or more complex jobs typically get a visit.

When to call us in The Stocks

Sometimes the sealant fails because something behind it is moving or wet: a loose panel, a leaking waste or water coming through the wall. We look for it before resealing and say if it needs a plumber or another trade.

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

  • Stained sealant around pans and urinals
  • Sealant laid over old silicone and now peeling
  • Open joints along basins and vanity units
  • Black mould inside silicone joints that cleaning can’t shift

At a school such as Wittersham Church of England Primary School, changing rooms and kitchens need cleanable joints as much as the toilets.
