About our washroom sealing in Wiston

When mould has spotted a silicone joint, more cleaning won’t remove it. The growth is inside the sealant, which is why it comes back however often it is treated. Replacing the bead is the lasting treatment. Site teams most often ask us about black mould inside silicone joints that cleaning can’t shift and split or peeling sealant at shower trays, on IPS panels and cubicles, kitchens and tea points and urinals and WCs. Whether you call it commercial sealant work, mastic application or joint sealing, in Wiston it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

For washroom work around Wiston, we plan so every room on the list is done in one trip where possible. Photos of each washroom and a count of rooms help us quote and plan.

We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant.

When to call us in Wiston

Low-level joints get hit by mop buckets, cleaning trolleys and feet, especially at floor edges and around urinals and WC pans.

It’s worth sending us details if you spot any of the following:

  • Gaps where vanity tops meet the wall
  • Resealing that didn’t last because the old bead stayed
  • Panel joints letting water behind
  • Black mould inside silicone joints that cleaning can’t shift

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

Questions to ask before you book

  • The terms of the workmanship guarantee
  • Their public liability cover
  • Which product they’ll use, and why it suits the joint
  • Health and safety accreditation such as CHAS

When something else is needed

Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is one of these:

  • Condensation from failed extract fans
  • Failed tanking beneath a wet-room floor or behind tiles
  • Vanity carcasses that have swollen

Not sure which it is? You can give us a call on 01277 525 020 or email a schedule or drawings and we’ll tell you honestly.

What we seal

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

Why deal with it now?

Leaving the job until a shutdown often means living with it for months. Phasing lets it happen now, with facilities kept in use. Buildings that aren’t in daily use, such as halls and seasonal premises, may let water in unnoticed, giving water time to get in. Early resealing prevents it.

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Why appoint us

  • Sealing commercial buildings since 2005
  • Colours chosen to suit frames, cladding or finishes where possible
  • Our applicators hold CSCS cards
  • Fully insured

General trades versus a specialist

Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Different surfaces, different methods

Changing rooms and gyms

Shower areas, wet floor edges and vanity areas all have sealant joints, and we survey them together.

Wet-room floors and floor-to-wall joints

Changing rooms and accessible showers often have wet floors so the edges are checked carefully.

Diagnose, treat, sign off

Site rules come first: signing in, inductions and any permit to work. With the paperwork done, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. Jobs near Wiston are often grouped with others in the same area, to make the most of each trip. Let us know if your dates have any give.

  1. Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
  2. We agree which rooms close and when, so users always have somewhere to go.
  3. Failed silicone is removed completely and the surfaces cleaned of every trace.
  4. We clean and dry every surface so the new sealant can grip.
  5. New sanitary silicone with anti-mould additives goes in and is tooled neat.
  6. Rooms reopen after the product’s cure time, and we move to the next.

Preparing the site

  • Arrange parking or a loading space
  • Let building users know which areas are affected
  • Confirm the product named in the specification

Advice

Questions about Wiston

Will the toilets in our Wiston building be out of use?

Not all at once. We take one block of facilities at a time. Sanitary silicone needs time to cure before the area is used, and we’ll tell you how long for the product used.

Which documents can you supply for work in Wiston?

RAMS, insurance certificate, CSCS details: list what the site needs and we will confirm it with the quote. Our applicators are CSCS-carded, and we carry £5m public liability insurance.

When is resealing likely to be due?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Who decides which product is used?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Do you take on multi-site work?

Yes. A group of buildings can go on one quote, with one point of contact across South East England, Greater London and Scotland.

How do I request a quote?

You can use the quote form on this site; alternatively, phone 01277 525 020 or use the quote form. Photos, drawings or a joint schedule help us quote quickly.

Do you phase washroom resealing?

Just the room being resealed is out of use. Each room reopens after the sealant’s cure time and we start the next.
