Washroom sealing across Westerham

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

Questions we are asked in Westerham

Would you work within a site like Tandridge Priory?

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 a smaller place like Westerham outside your area?

No. Small places get the same service as large ones. We work across Greater London and the South East. Good photographs up front let us bring everything on the first visit.

Do you need to remove the old sealant?

We strip every bit of the failed bead and wipe away the residue first. It’s the difference between a joint that lasts and one that peels.

Can you reseal washrooms in healthcare buildings?

Yes, healthcare and care settings are part of our work. Any records you need are confirmed with the quote.

How do we ask for 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 do you deal with asbestos in old sealant?

The duty to manage asbestos sits with the building’s dutyholder, so we’ll ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.

Do you guarantee washroom sealing?

Every job carries our 12-month guarantee. It covers our workmanship rather than damage, leaks from plumbing or ventilation problems.

How we handle washroom sealing in Westerham

Black spotting along a sealant bead is not a cleaning problem. The mould has rooted into the silicone itself so it returns whatever the cleaning regime. Replacing the bead is the lasting treatment. We work on IPS panels and cubicles, kitchens and tea points and vanity units and basins, and what we are called in for most is sealant stained black around basins and showers and failed joints along IPS and cubicle panels. Most enquiries from Westerham start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

In and around places like Westerham, hospitality kitchens and toilets see heavy use in busy spells. Smooth, sealed joints at worktops, sinks and wall cladding make cleaning easier.

We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application.

Owners, agents and contractors

CHAS accredited and a Constructionline member, we make supplier vetting simple. We’re fully insured, and our insurance certificate can go with the quote.

Whether you’re a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

What affects the price in Westerham

A fixed quote reflects the actual work. It allows for:

  • Joint width, depth and condition
  • The site’s rules and procedures
  • How accessible the joints are
  • Whether the work must be split into stages

There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we’ll price your job on its own details.

What we need to price the job

The more we know, the firmer the quote. When you get in touch, include:

  • The type of building and who uses it
  • The site address and postcode
  • Asbestos survey details if the building is older
  • Your programme or deadline

The quickest route to a quote is a few photographs and the site postcode. Upload them with the quote form, or speak to us on 01277 525 020 or email us to discuss it first.

Surface by surface

Urinals and WC pans

Urinal backs, troughs and slab joints are resealed with sanitary silicone once the whole of the old bead has gone.

IPS and cubicle panels

A panel that has already swollen won’t be fixed by sealant, and any we come across will be pointed out.

Why deal with it now?

When a washroom looks worn, a refit isn’t the only answer. Where tiles, panels and fittings are sound, new sealant may be enough to put it right for now. A failed joint lets water into a building whatever its size. Early resealing avoids the damage that follows a leak.

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.

Why appoint us

  • Work to your specification and the manufacturer’s guidance
  • One contact handling all your sites
  • A Constructionline member, so easy to vet
  • Colour agreed before work starts

How a job runs

Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. Work in places the size of Westerham is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.

  1. Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
  2. A phasing plan keeps part of the building’s facilities in use at all times.
  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. Rooms reopen after the product’s cure time, and we move to the next.

Getting the site ready

  • Tell us which areas need to stay in use
  • Tell us what induction or permit system the site runs
  • Share your working hours and any access restrictions

When it isn’t the sealant

Being straight saves everyone time. New sealant won’t cure:

  • Panel boards already damaged by water
  • Water from plumbing, not from a joint
  • Loose panels, vanity units or tiles, which need fixing first
