Need washroom sealing in Leigh Green?

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Our process

In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before the next one starts. If others near Leigh Green need work, visits can be combined. You’ll have a fixed quote before work starts.

  1. We survey each room, count the joints and note anything behind them that needs another trade.
  2. We agree which rooms close and when, so users always have somewhere to go.
  3. Failed silicone is removed completely and the surfaces cleaned of every trace.
  4. Joints are cleaned, degreased and dried before sealing.
  5. A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
  6. Each room is handed back once the sealant has had its cure time.

Before we start on site

  • Clear stock, furniture or equipment away from the joints
  • Confirm the product named in the specification
  • For older buildings, check the asbestos register before work

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. For smaller jobs, photographs and a description will do.

About our washroom sealing in Leigh Green

Not every silicone belongs in a washroom. Sanitary silicone contains additives that resist mould, and neutral-cure versions avoid the damage acetoxy types can do to some metals, stone and mirror backings. In food areas, hygienic or food-safe sealants are used where food contact is possible. If you have stained or open joints at kitchen sinks and worktops and split or peeling sealant at shower trays, we can put it right, whatever the surface. A single leaking joint is often how a building in Leigh Green first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Smaller places such as Leigh Green 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.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

Common questions from Leigh Green clients

Can you take on a job at a hospital such as West View Hospital?

Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.

Is Leigh Green too far out for you?

No. Small places get the same service as large ones. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.

Can washrooms stay open while you work?

The work is phased so there are always facilities open. One washroom, one bank of cubicles or one changing room is done at a time around your site hours and access windows.

Will your applicators have CSCS cards?

Yes. We use CSCS-carded applicators, as many construction sites ask for.

Which silicone is right for commercial washrooms?

An anti-mould sanitary silicone for most washroom joints. We use neutral-cure versions on stone, some metals and near mirrors.

How long before the toilets can reopen?

Cure times vary by product and temperature. You’ll get a reopening time for each area, and signs stay up until then.

What happens if old sealant might contain asbestos?

Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.

Commercial washrooms in Leigh Green

Leigh Green has a number of hotels close by, all within 2 miles. Hotel en suites take daily use, and tired silicone at trays and basins is one of the first things guests notice. Rooms are done in turn so most stay available. Leigh Green is about 46 miles from central London. Office toilets in the commuter belt are in use from first arrivals to last departures, which is why the work is phased.

At a hotel such as The Woolpack Hotel (1.2 miles west of Leigh Green), the quieter weeks are the time to reseal bathrooms. Clinical washrooms at sites like West View Hospital, 1.7 miles west of Leigh Green, are scheduled with the ward so the room is out of use for as little time as possible.

Leigh Green is about 8 miles south-west of Ashford, in Kent. Any commercial site in Leigh Green is covered. 931 places across Kent fall within our area, including Leigh Green. We also cover Brighton, around 40 miles from Leigh Green.

Site staff or a sealant specialist?

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Commercial clients in Leigh Green

Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, and our applicators hold CSCS cards.

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

Keeping the joints sound

Problems stay small when the joints are checked regularly. In particular:

  • Include joints in routine washroom inspections
  • Leave signs up until the cure time is over
  • Report split joints at trays and basins early
  • Clean sealant with gentle products and a soft cloth

Any failure in our workmanship within the 12-month guarantee is ours to put right. After that, a routine look catches failing joints early.

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

Basins and vanity tops

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

Urinals and WC pans

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

When to call us in Leigh Green

Panels and vanity units move slightly in use and trays shift slightly with each user. If the joint wasn’t laid to take that movement, it tears or peels away.

Typical triggers for a call:

  • Mould spotting along silicone joints
  • Gaps where vanity tops meet the wall
  • Kitchen worktop joints that can’t be kept clean
  • Panel joints letting water behind

Office washrooms on sites such as Pickhill Business Centre (to the south-west of Leigh Green) are in use all working day, so resealing is phased to keep some open.
