Washroom sealing for businesses in Ashurst

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Honest limits

We check first that sealant really is the fix. It won’t put right:

  • Hollow tiles or loose panels behind the joint
  • Water escaping beneath the floor rather than through a joint
  • Panel boards already damaged by water

Not sure which it is? You can give us a call on 01277 525 020 or send photos by email and we will tell you honestly.

Surfaces we seal

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

Washroom sealing in Ashurst

From one staff toilet in Ashurst to washrooms across a whole estate, we work the same way: send details, get a fixed quote, we seal, guaranteed. Photos and a rough count of basins, urinals, showers and cubicles help us give a quick quote and a site visit is an option. The enquiries we see most involve failed joints along IPS and cubicle panels and stained sealant around pans and urinals, on urinals and WCs, kitchens and tea points and vanity units and basins. For commercial sealant work in Ashurst, you deal with one contact from quote to sign-off, whether it’s one building or several.

In and around smaller places like Ashurst, washroom work is often in halls, pubs, primary schools, care homes and holiday accommodation. Mould gets into sealant in any washroom that doesn’t dry out, and once it’s in, the sealant is replaced.

The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Owners, agents and contractors

If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

On site: what to expect

Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. If others near Ashurst need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. We survey each room, count the joints and note anything behind them that needs another trade.
  2. We agree which rooms close and when, so users always have somewhere to go.
  3. We strip out the old bead and clean off the residue left behind.
  4. Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
  5. A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
  6. Each room is handed back once the sealant has had its cure time.

Preparing the site

  • Tell us what induction or permit system the site runs
  • Send asbestos survey details if the building is pre-2000
  • Move anything stored against the joints

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. For smaller jobs, photos and a description will do.

For a hall at a building such as The Parish Church of St James, resealing the kitchen and toilets can be fitted between bookings.

Keeping the joints sound

Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:

  • Brief cleaning staff to treat joints gently
  • Clear standing water from shower floors where possible
  • Keep a record of which washrooms need attention
  • Include joints in routine washroom inspections

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

Inspectors look at whether kitchen surfaces can be kept clean. Failed sealant around sinks and worktops is easy to put right in good time.

Should maintenance staff do it?

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

Different surfaces, different methods

Urinals and WC pans

We reseal around urinals and pans with a sanitary grade after the old bead and residue are removed.

Showers and trays

If a tray moves too much or is cracked, it needs attention first and we flag that beforehand.

Questions we’re asked in Ashurst

Is Ashurst too far out for you?

No. Places such as Ashurst are covered as much as the big towns. 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.

Will all the washrooms in our Ashurst building be closed at once?

Rarely all at once: work is phased so some facilities are always available. We will tell you the curing time for the product before we start.

What sealant do you use in washrooms?

It depends on the joint. Most washroom joints take sanitary silicone while kitchens may need a food-safe grade.

How long before the toilets can reopen?

The silicone needs time to cure before water reaches it. Phasing is planned with the cure time in mind so facilities are never short.

How do you choose the sealant?

The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

Can you send site paperwork?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.

Will you come and look before quoting?

That depends on the size and complexity of the job. Simple work can often be priced from photos, and bigger or more complex jobs typically get a visit.
