Questions about Stoke

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

Normally only some of them, for a short time. We work in phases so other facilities stay open. We will tell you the curing time for the product before we start.

Do you take on work at healthcare sites like Andover War Memorial Hospital?

Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.

Can you reseal washrooms in healthcare buildings?

Yes. We work to your estates and infection-control requirements and any site permits. The work is phased around patients or residents.

What happens if old sealant might contain asbestos?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.

Can you clean the mould off instead of resealing?

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.

What site paperwork can you supply?

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

Do you need to remove the old sealant?

The failed bead is always removed. New silicone won’t stick to the old so a bead over the top fails quickly.

How we handle washroom sealing in Stoke

From one staff toilet in Stoke to washrooms across a whole estate, we work the same way: details first, then a fixed quote, then the work, then the 12-month guarantee. A few photographs and a count of fittings are enough for a quick quote, or we can arrange a visit. We work on accessible toilets and changing rooms, showers, trays and wet room floors and IPS panels and cubicles, and what we’re called in for most is resealing that didn’t last because the old bead stayed and discoloured joints around urinals and WC pans. Searching for sealant specialists in Stoke? We’ve been sealing commercial buildings since 2005.

Farm shops, cafés and venues in converted rural buildings around places like Stoke have busy toilets and kitchens. Tell us your opening times and quiet periods and we will plan around them.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Site staff or a sealant specialist?

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. For that reason, many FMs and contractors use a sealant specialist from the outset.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Our process

Site rules come first: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you, and each area is checked before we leave it. Rural sites near Stoke may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.

  1. We agree which washrooms close and when.
  2. Leaks, loose panels or damp are pointed out first.
  3. Old sealant is stripped and the faces prepared.
  4. The right sanitary or food-safe sealant is applied.
  5. We give you a reopening time for every room.

Getting the site ready

  • Share your working hours and any access restrictions
  • Flag any permit to work we’ll need
  • Let building users know which areas are affected

Request a quote

Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

How the quote is worked out

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

  • How accessible the joints are
  • The product specified
  • The size and state of each joint
  • Whether old sealant has to be cut out first

The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

Before you send an enquiry

It doesn’t need to be a full survey. A few details are enough to get going:

  • The type of building and who uses it
  • Approximate linear metres or a joint schedule
  • Specification clauses that apply
  • How the joints are reached, and at what height

Different surfaces, different methods

Showers and trays

Shower trays move under foot and are wet all day. Tray joints are where many washroom leaks start.

Wet-room floors and floor-to-wall joints

Wet floors are common in accessible showers and changing rooms so the edges are checked carefully.

Wet areas in Stoke’s workplaces

Central London is about 60 miles from Stoke, in a commuter belt where offices and business parks are common. Office washrooms on business parks see heavy weekday use, so we work a block of facilities at a time.

Pupil toilets at schools like St Mary Bourne Primary School take heavy daily use, and the holidays give the window to reseal.

Stoke is about 5 miles north-east of Andover, in Hampshire. We send applicators to Stoke for washrooms and wet areas, handled exactly as we handle every other area. Our Hampshire coverage takes in 723 places, large and small. Reading is covered too, some 23 miles away.

Common problems we fix in Stoke

Daily commercial cleaning wears sealant faster than people expect. Strong chemicals, scourers and jet washing roughen, discolour or lift a bead so grime sticks to the damaged surface.

Typical triggers for a call:

  • Split or peeling sealant at shower trays
  • Mould spotting along silicone joints
  • Gaps where vanity tops meet the wall
  • Resealing that didn’t last because the old bead stayed

For a site such as Andover War Memorial Hospital (4.6 miles south-west of Stoke), sanitary joints in clinical areas need sound, cleanable sealant and a careful method.

What to look for in a quote

  • Their plan for phasing and protecting the area
  • What site paperwork they can supply
  • How long is the guarantee, and what does it include?
  • Is the sealant right for the movement and the substrate?

How to choose a sealant contractor

Why act early in Stoke

A failed joint behind a basin or along a shower tray lets water run where it shouldn’t. In a commercial building that can mean damaged boards, stained ceilings on the floor below and odours which costs more to fix than a reseal. Around Stoke, 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.

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
