FAQs: Stede Quarter

Do we have to close all our washrooms in Stede Quarter for resealing?

Not all at once. We take one block of facilities at a time. Each area is handed back once the sealant has cured enough to use.

Is a hospital such as Benenden Hospital somewhere you can work?

Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.

Do you work in hospitals, clinics and care homes?

We do. Your infection-control rules, estates requirements and permits are followed, and phase the work so areas keep facilities.

Will you quote for a small job?

Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.

Do you cover Stede Quarter?

Yes. We cover Stede Quarter, and you can speak to us on 01277 525 020 or email the details over to get started.

How long do sealant joints last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

How do we ask for a quote?

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

Washroom sealing in Stede Quarter

In a busy washroom, the sealant normally gives up long before the tiles or fittings. Basin tops, urinal backs, panel joints and shower trays put it under water, chemicals and daily cleaning, and once mould grows into it, it can’t be scrubbed out. We strip it out and lay new anti-mould sanitary silicone. We work on accessible toilets and changing rooms, showers, trays and wet room floors and kitchens and tea points, and what we’re called in for most is resealing that didn’t last because the old bead stayed and panel joints letting water behind. Whether you call it commercial sealant work, mastic application or joint sealing, in Stede Quarter it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Smaller places such as Stede Quarter still have commercial washrooms and kitchens: in halls, pubs, schools, care homes and farm-based businesses. Mould gets into sealant in any washroom that doesn’t dry out, and once it’s in, the sealant is replaced.

Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

When it isn’t the sealant

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • A room that stays damp because ventilation isn’t working
  • Swollen or delaminated boards behind panels or vanity tops
  • Leaking pipes, traps, wastes or cisterns, which need a plumber

If in doubt, give us a call on 01277 525 020 or email the details over and we will say what we think.

Joints and surfaces we work on

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

On site: what to expect

When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work typically takes between a morning and a week or so, set by the number of rooms and the phasing you need. Jobs in and around smaller places like Stede Quarter are normally planned as a single visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  1. Every room is surveyed and the failed joints listed.
  2. The fixed quote sets out the rooms, the products and the phasing.
  3. Old sealant is removed completely and the faces cleaned.
  4. Each joint is cleaned and left dry.
  5. New anti-mould sealant goes in and is tooled neat.
  6. Rooms reopen after the cure time.

Work for main contractors and building owners

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.

Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

What we are called out for in Stede Quarter

Commercial cleaning is harder on sealant than everyday use. Strong chemicals, scourers and jet washing roughen, discolour or lift a bead so grime sticks to the damaged surface.

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

  • Black mould inside silicone joints that cleaning can’t shift
  • Open joints along basins and vanity units
  • Urinal joints that look unhygienic
  • Failed sealant in a tea point or staff kitchen

If you manage an office at a site such as Business Park, 2.6 miles south of Stede Quarter, the washrooms and tea points can be done a floor at a time.

How to choose a sealant contractor

Keeping the joints sound

Regular inspection catches problems early. Specifically:

  • Make sure washroom ventilation is running
  • Report split joints at trays and basins early
  • Note failing joints building by building
  • Add sealant joints to planned maintenance checks

We hand each area back once the silicone has had the cure time the product needs. We’ll tell you when the wet areas can be used, and it helps if signs stay up until then.

Leaks through tray and wet-floor joints can go unseen until a ceiling marks below. By then, other trades may be needed as well so failed joints are worth acting on quickly.

Why deal with it now?

Gaps and mould in joints give dirt and bacteria somewhere to sit, and in kitchens, clinics and schools that is a real concern. A smooth, sealed joint can be cleaned properly. Converted and older buildings near places like Stede Quarter tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

The specified product makes a difference, and so does the preparation. Access, phasing and site requirements come into it too.
