Washroom sealing across Dunton Green

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

What the job involves on each surface

Urinals and WC pans

Floor joints around WC pans are often forgotten. They are checked with everything else.

IPS and cubicle panels

Cubicle and IPS panels move when leaned on or knocked so the bead needs to cope with it. We check fixings before sealing.

Washroom sealing for commercial buildings in Dunton Green

In a commercial washroom, sealant is normally the first thing to wear out. Basin tops, urinal backs, panel joints and shower trays put it under water, chemicals and daily cleaning and mould that roots into it can’t be cleaned away. The fix is to remove it completely and reseal with sanitary silicone containing anti-mould additives. If you are dealing with stained sealant around pans and urinals and gaps where vanity tops meet the wall, we can help, on vanity units and basins, showers, trays and wet room floors and accessible toilets and changing rooms alike. A single leaking joint is often how a building in Dunton Green first comes to us: we look at the rest while we are there and tell you what we find.

Rural businesses near smaller places such as Dunton Green, from cafés to event venues, rely on washrooms and kitchens that stay clean. We plan the work around bookings and opening times.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

Doing it in-house

Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

Site maintenance staff can often handle a short internal joint. 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.

Maintenance after handover

Keep the joints in good shape with a few simple steps:

  • Avoid scourers and harsh descalers on silicone
  • Squeegee showers and trays after busy periods
  • Report split joints at trays and basins early
  • Keep washrooms out of use until we say the sealant has cured

Add washroom sealant to routine inspections. Check for mould spots, splits, lifting edges and open joints at trays, basins and urinals and log what you find.

Boards behind panels and vanity tops can swell when water gets past a failed joint. After that, those parts need replacing rather than resealing.

Wet areas in Dunton Green’s workplaces

The area within 2 miles of Dunton Green holds a number of hotels. En suite bathrooms, staff changing rooms and kitchens all need their sanitary silicone renewed in time. We work a handful of rooms at a time, so the hotel keeps letting the rest. Dunton Green lies roughly 18 miles out 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.

For a hall at a building such as St John's Church, resealing the kitchen and toilets can be fitted between bookings. At a hotel such as Donington Manor Hotel, 0.7 miles north-west of Dunton Green, the quieter weeks are the time to reseal bathrooms. Office toilets at parks like Sevenoaks Business Centre (1.1 miles east of Dunton Green) take steady weekday use, and mouldy silicone soon shows.

Dunton Green is about 1 mile north-west of Sevenoaks, in Kent. We send applicators to Dunton Green for washrooms and wet areas, handled exactly as we handle every other area. 931 places across Kent fall within our area, including Dunton Green. There’s a separate page for London, about 18 miles away.

We take on washrooms and wet areas across the TN13 and TN14 postcode area, whatever the building.

Our process

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Jobs in and around smaller places like Dunton Green are usually planned as a single visit, so photos and measurements up front really help. That way the right products come on the day.

  1. First, the phasing is agreed so facilities stay open.
  2. Leaks, loose panels or damp are pointed out first.
  3. Failed sealant and residue are stripped out.
  4. The right sanitary or food-safe sealant is applied.
  5. We confirm reopening times for each washroom.

What we need from you

  • Have the specification and drawings to hand
  • Share the asbestos register for older buildings
  • Agree which areas must stay open

What affects the price in Dunton Green

Sealant work doesn’t have a standard rate, because every site is different. What we take into account:

  • Any access equipment needed
  • Quantities, in metres or numbers
  • Phasing around occupants
  • Joint width, depth and condition

The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.

What to include in your enquiry

However big the job, the same details help:

  • How the joints are reached, and at what height
  • The postcode of the building
  • Any dates the work must fit around
  • Specification clauses that apply

Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, phone 01277 525 020 or email a schedule or drawings.

Common questions from Dunton Green clients

Is Dunton Green off your patch?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Will our hotel in Dunton Green need to close for the work?

Rarely, if ever. We take a few rooms out at a time. Housekeeping and our team agree each day’s rooms.

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. Step one needs little more than photos and a postcode.

Will your applicators have CSCS cards?

Yes. Our applicators hold CSCS cards, as many construction sites ask for.

How long does a job like this take?

We plan the time on site around your programme and access. You’ll have an expected duration with the quote.

Is it OK to put new silicone on top of the old?

We always remove it. Fresh silicone can’t key to an old bead so a bead over the top fails quickly.

Is colour matching possible?

Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.
