Washroom sealing across Wateringbury

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

When it isn’t the sealant

Honesty saves time and money. Fresh joints won’t solve:

  • Condensation from failed extract fans
  • Failed tanking beneath a wet-room floor or behind tiles
  • A dripping waste or valve behind a panel

If in doubt, phone 01277 525 020 or email drawings and photos and we’ll say what we think before you book.

Joints and surfaces we work on

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

About our washroom sealing in Wateringbury

Since 2005 we have resealed commercial washrooms for facilities teams, contractors and building owners. We are CHAS accredited and a Constructionline member, with CSCS-carded applicators. There is public liability insurance behind every job. Every resealed washroom carries our 12-month guarantee. Site teams most often ask us about sealant laid over old silicone and now peeling and users noticing mouldy joints, across kitchens and tea points, vanity units and basins and showers, trays and wet room floors. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Wateringbury is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

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

A 12-month guarantee applies to all our work in Kent. Should something we installed fail, call 01277 525 020 or email the details over and we will come back to it.

Why deal with it now?

Water gets behind panels and under floors through a failed joint. In a commercial building that can mean damaged boards, stained ceilings on the floor below and odours, and fixing that takes far more work than resealing. Converted and older buildings near places like Wateringbury tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

Why appoint us

  • A range of standard colours, depending on the product
  • Products installed to the manufacturer’s instructions
  • A Constructionline member, so easy to vet
  • 12 months’ guarantee on every job

Take a look at how commercial sealant jobs are priced or how we’re accredited.

Quoting for work in Wateringbury

There’s no standard rate for sealant work, since sites vary so much. What we look at:

  • How much there is to seal
  • The site’s rules and procedures
  • Any access equipment needed
  • Removal of failed or old sealant

The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site rules also count.

What we need to price the job

To price the job accurately, we need to understand the site. Send us:

  • Whether an asbestos survey exists
  • The postcode of the building
  • When you need the work done
  • Access details, including height

Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. To get it moving, call 01277 525 020 or email us.

Surface by surface

Showers and trays

Shower joints in hotels, gyms and workplaces work hard. Every joint is stripped, degreased, dried and given a new bead.

Wet-room floors and floor-to-wall joints

Wet-room floors and the joints where flooring turns up the wall need to stay sound. Floor perimeters and sealant joints near drains are resealed.

How a job runs

Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us. Rural sites near Wateringbury may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.

  1. Every room is surveyed and the failed joints listed.
  2. You get a fixed quote with the phasing plan.
  3. The whole of the old bead is removed.
  4. Each joint is cleaned and left dry.
  5. A sanitary silicone bead is laid and given a smooth tooled finish.
  6. Each area is handed back when ready.

Preparing the site

  • Confirm the product named in the specification
  • For older buildings, check the asbestos register before work
  • Let building users know which areas are affected

Wet areas in Wateringbury’s workplaces

Wateringbury lies roughly 28 miles out from central London, in a commuter belt where offices and business parks are common. Business park offices have washrooms in daily use by staff, and resealing in phases keeps facilities available.

Halls linked to places like Church of St John the Baptist host groups all week, which is hard on kitchen and toilet sealant. For a school such as Wateringbury Church of England Primary School, washroom and kitchen sealant can be renewed around term dates. At a university such as University for the Creative Arts - Maidstone, 3.5 miles to the east of Wateringbury, summer is the usual window for resealing residence bathrooms.

Wateringbury is about 5 miles west of Maidstone, in Kent. Wateringbury sits inside our coverage and the rest of Kent, with the same fixed quotes and 12-month guarantee as everywhere else. Across Kent, 931 places are covered, including Wateringbury. For work in that direction, see our London page.

Questions about Wateringbury

Would you work within a site like Oakwood Hospital?

Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Is a smaller place like Wateringbury outside your area?

Not at all. Wateringbury is within our area. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

What do you charge?

Each job is quoted on its own details. For yours, give us a call on 01277 525 020 or use the quote form with a description of the work.

Can weather delay the job?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

Is there a guarantee on the work?

Our workmanship has a 12-month guarantee backed by public liability insurance.

How long will the new sealant last?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

Do you phase washroom resealing?

Just the room being resealed is out of use. Rooms go back into use once the sealant has cured and we start the next.

Keeping the joints sound

Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Avoid scourers and harsh descalers on silicone
  • Note failing joints building by building
  • Include joints in routine washroom inspections
  • Act on the first split you see at a shower tray

Squeegeeing showers and trays after heavy use helps. Joints that sit wet for hours fail sooner.

In food areas, cleanability is something environmental health officers look at. Failed sealant around sinks and worktops is easy to put right in good time.
