Washroom sealing in Chilson

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. Most enquiries involve failed sealant behind washroom basins and open joints at the base of cubicle panels, on urinals and WCs, IPS panels and cubicles and showers, trays and wet room floors. Most enquiries from Chilson start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Community buildings around smaller places like Chilson have kitchens and toilets used by many people. Resealing sinks, worktops and WCs with anti-mould silicone keeps them clean and watertight.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Questions we’re asked in Chilson

Is Chilson too small for you to travel to?

Not at all. Chilson is within our area. We work across Greater London and the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

What paperwork can you provide for a job in Chilson?

RAMS, insurance certificate, CSCS details: list what the site needs and we will confirm it with the quote. We’re CHAS accredited and a Constructionline member, with £5m public liability insurance and CSCS-carded applicators.

Are your applicators CSCS-carded?

Yes. If you need card details for site access, let us know and we will send them with the quote.

Who decides which product is used?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

What guarantee comes with washroom resealing?

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

Do you have public liability insurance?

Yes. Our insurance certificate can be sent alongside the quote.

Do you need to remove the old sealant?

The whole of the old bead is removed and the surfaces cleaned before resealing. It’s the difference between a joint that lasts and one that peels.

What the job involves on each surface

Urinals and WC pans

The joint between a pan and the floor is easy to overlook. We include them in the survey.

Kitchens and tea points

Kitchen joints need to be smooth and sealed so they can be cleaned properly. Where food contact is possible, we use a hygienic, food-safe sealant.

What happens if it’s left?

Gaps and mould in joints give dirt and bacteria somewhere to sit which matters most in healthcare, food and education settings. Sound, smooth joints are much easier to keep clean. Around Chilson, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.

What a job costs comes down to how many linear metres there are, what has to come out first and how the joints are reached. Call for a fixed quote once you have the details.

Why us?

  • Clear, fixed quotes
  • Fully insured, including public liability cover
  • Old sealant cut out, never sealed over

Looking after the joints

Cleaning and maintenance staff play a part too. Share these points with them:

  • Share your site rules when you send details
  • Keep extract fans working and vents clear
  • Clean sealant with gentle products and a soft cloth
  • Report split joints at trays and basins early

Include sealant joints in your planned maintenance checks. Check for mould spots, splits, lifting edges and open joints at trays, basins and urinals and log what you find.

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

From enquiry to sign-off

Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use. For a building around Chilson, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.

  1. We agree which washrooms close and when.
  2. Leaks, loose panels or damp are pointed out first.
  3. Failed sealant and residue are stripped out.
  4. We reseal with the grade suited to each area.
  5. We confirm reopening times for each washroom.

Before we start on site

  • Make sure the joints can be reached
  • Tell us which areas need to stay in use
  • Send any specification or drawings in advance

Getting a fixed quote

A handful of photos and a postcode is the fastest way to a quote. Send them through the quote form, or ring 01277 525 020 or send details through our quote form to discuss it first.

Related advice

Common problems we fix in Chilson

We often find acrylic caulk or general-purpose sealant in joints that should have sanitary silicone. They aren’t made for constant wetting and they discolour and fail early.

Things that usually lead to an enquiry:

  • Black mould inside silicone joints that cleaning can’t shift
  • A new bead over an old one coming away
  • Panel joints letting water behind
  • Split or peeling sealant at shower trays

If you manage an office at a site such as Southill Business Park (2.7 miles south-east of Chilson), the washrooms and tea points can be done a floor at a time.

  • Their approach to joint depth and backing
  • Their pre-qualification and accreditations
  • How the joint faces will be prepared and primed
