Washroom sealing in Chitty

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Why deal with it now?

Washrooms shape how visitors judge a building. Guests, clients, pupils and patients notice stained joints before they notice much else. Fresh sanitary silicone lifts a room with very little disruption. Halls, stores and units around places like Chitty may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.

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

Why clients in Chitty choose us

  • CSCS-carded applicators
  • Sealing commercial buildings since 2005
  • Colours confirmed for the specified product
  • One contact handling all your sites

Washroom sealing in Chitty

Accessible toilets, shower rooms and changing rooms have joints that work harder than most: shower trays, wet-room floor edges, basins and floor-to-wall junctions. An open joint there lets water track under flooring or behind wall panels, so we look at them closely. If you’re dealing with shower tray joints that have opened up and kitchen worktop joints that can’t be kept clean, we can help, on vanity units and basins, kitchens and tea points and IPS panels and cubicles alike. For commercial sealant work in Chitty, you deal with one contact from quote to sign-off, whether it’s one building or several.

Halls and community buildings near places like Chitty 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.

A 12-month guarantee applies to all our work in Kent. If an installation problem shows up, phone 01277 525 020 or use the quote form and we will arrange a return visit.

On site: what to expect

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself usually takes half a day to a day per washroom, depending on the number of fittings, and we clear our waste as we work. Smaller jobs around Chitty can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  1. We inspect each washroom and record the joints to be resealed.
  2. You get a fixed quote with the phasing plan.
  3. Old sealant is removed completely and the faces cleaned.
  4. Joints are degreased and dried.
  5. A sanitary silicone bead is laid and given a smooth tooled finish.
  6. Each area is handed back when ready.

Preparing the site

  • Share the asbestos register for older buildings
  • Tell us which areas need to stay in use
  • Arrange parking or a loading space

What we are called out for in Chitty

Mop buckets, trolleys and knocks from users damage joints near the floor, especially at floor edges and around urinals and WC pans.

Common reasons buildings call us in:

  • Resealing that didn’t last because the old bead stayed
  • Failed sealant in a tea point or staff kitchen
  • Sealant stained black around basins and showers
  • Split or peeling sealant at shower trays

Healthcare washrooms on sites such as St Martins Hospital, 5.8 miles to the south-west of Chitty, are resealed area by area, under the site’s own infection-control rules.

What to look for in a quote

  • How long is the guarantee, and what does it include?
  • How joint depth will be controlled
  • Which product they’ll use, and why it suits the joint

How to choose a sealant contractor

Chitty: questions and answers

Can you take on a job at a hospital such as St Martins Hospital?

Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.

Do we have to close all our washrooms in Chitty for resealing?

Usually only some of them, for a short time. We work in phases so other facilities stay open. We will tell you the curing time for the product before we start.

Is old silicone taken out first?

We always remove it. Fresh silicone can’t key to an old bead, so sealing over it soon peels.

What about RAMS and site documents?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.

Do you do washroom sealing in healthcare settings?

We work in clinics, hospitals and care homes. Tell us what records you need and we will confirm with the quote before we start.

Do your applicators hold CSCS cards?

Yes. We use CSCS-carded applicators.

How do I request a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.

How the job changes by surface

Basins and vanity tops

Basin joints get wet every time someone washes their hands, so the wall joint and bowl surrounds tend to fail before anything else. We remove the old bead and lay a fresh one of sanitary silicone.

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 will plan around them.

Building owners, agents and FMs in Chitty

Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

Building owners and managing agents use us on sealant work across single buildings or whole portfolios around Chitty. Several sites can go on one quote, so there’s one set of paperwork to deal with.

Sanitary sealant for Chitty buildings

With the shore within about 3 miles, Chitty counts as a coastal location, and coastal hotels, guest houses and holiday sites tend to fill up in the busy months. Washrooms used guest after guest wear their sanitary silicone faster, so resealing in the quieter months keeps rooms ready. Central London is about 57 miles from Chitty, within the office belt around the capital. Office washrooms on business parks see heavy weekday use, and resealing in phases keeps facilities available.

If you manage an office at a site such as Chislet Business Park, which lies south-west of Chitty, the washrooms and tea points can be done a floor at a time. Church halls and community buildings, such as those at Church of St Mary the Virgin, have kitchens and toilets used by many groups, and their sanitary sealant works hard.

Chitty is about 4 miles south-east of Herne Bay, in Kent. Our applicators travel to Chitty for work on washrooms and wet areas. We work across 931 places in Kent. London is covered too, around 57 miles from Chitty.

Maintenance after handover

Once the work is signed off, these steps help:

  • Clean sealant with gentle products and a soft cloth
  • Don’t leave trays and floors sitting wet
  • Act on the first split you see at a shower tray
  • Respect the cure time before reopening each room

Mild cleaning products and non-abrasive cloths look after sanitary silicone best. Aggressive descalers, solvents and scouring pads shorten its life over time.

Mould in a joint spreads along the bead and into nearby grout and users notice. Dealing with it while it’s just the sealant keeps it simple.
