Need washroom sealing in Filching?

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

Site staff or a sealant specialist?

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

About our washroom sealing in Filching

Not every silicone belongs in a washroom. Sanitary silicone contains additives that resist mould, and neutral-cure versions avoid the damage acetoxy types can do to some metals, stone and mirror backings. In food areas, hygienic or food-safe sealants are used where food contact is possible. Most enquiries involve sealant stained black around basins and showers and failed sealant in a tea point or staff kitchen, on accessible toilets and changing rooms, urinals and WCs and vanity units and basins. Whoever orders the work in Filching, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

In and around smaller places like Filching, 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.

A 12-month guarantee applies to all our work. Should something we installed fail, phone 01277 525 020 or send details through our quote form and we will come back to it.

Aftercare for building managers

After handover, these steps help:

  • Don’t leave an open joint at a basin or tray
  • Include joints in routine washroom inspections
  • Note failing joints building by building
  • Make sure washroom ventilation is running

We hand each area back once the silicone has had the cure time the product needs. You will be told when showers and basins can be used again, and it helps if signs stay up until then.

A split joint at a shower tray can leak for a long time before anyone sees it. By then, other trades may be needed as well so failed joints are worth acting on quickly.

Different surfaces, different methods

Showers and trays

If a tray moves too much or is cracked, it needs attention first, and we’ll say so before resealing.

Wet-room floors and floor-to-wall joints

Wet-room floors and the joints where flooring turns up the wall need to stay sound. Floor perimeters and sealant joints near drains are resealed.

What we’re called out for in Filching

Commercial cleaning is harder on sealant than everyday use. Strong chemicals, scourers and jet washing roughen, discolour or lift a bead, and dirt and mould then get a foothold.

These are often picked up first by site or facilities staff:

  • Open joints along basins and vanity units
  • Failed joints along IPS and cubicle panels
  • Shower tray joints that have opened up
  • Failed sealant in a tea point or staff kitchen

Staff changing rooms and patient toilets at places like Eastbourne District General Hospital, 2.4 miles south-east of Filching, need cleanable, sound silicone.

Questions to ask before you appoint anyone

Diagnose, treat, sign off

Tell us your site hours and access windows and we will plan around them. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. Rural sites near Filching may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.

  1. We agree which washrooms close and when.
  2. Anything behind the joints that needs another trade is flagged.
  3. Old sealant is stripped and the faces prepared.
  4. We reseal with the grade suited to each area.
  5. We confirm reopening times for each washroom.

What we need from you

  • Point out any areas we must not close
  • Explain the parking and delivery arrangements
  • Warn occupants and staff about the work

What we can’t put right

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Hollow tiles or loose panels behind the joint
  • A room that stays damp because ventilation isn’t working
  • A dripping waste or valve behind a panel

If you’re not sure, just call the office on 01277 525 020 or send photos by email and we’ll give you a straight answer before you book.

What we seal

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

Common questions from Filching clients

Is a smaller place like Filching outside your area?

Not at all: smaller places are covered as well as 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.

Would you work within a site like Eastbourne District General Hospital?

Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Is it possible to just clean mouldy silicone?

Cleaning may lighten it, but the mould returns. We replace the sealant with an anti-mould sanitary grade and point out if ventilation is part of the problem.

Do you use special sealant for toilets and showers?

An anti-mould sanitary silicone in the majority of cases. We use neutral-cure versions on stone, some metals and near mirrors.

Is old silicone taken out first?

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.

Can weather delay the job?

Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

Do you have public liability insurance?

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