Need washroom sealing in South Stour?

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Our process

Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use. For work around South Stour, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  1. We inspect each washroom and record the joints to be resealed.
  2. You get a fixed quote with the phasing plan.
  3. Old sealant is removed completely and the faces cleaned.
  4. Joints are degreased and dried.
  5. New anti-mould sealant goes in and is tooled neat.
  6. Each area is handed back when ready.

What we need from you

  • Tell us what induction or permit system the site runs
  • Tell us which areas need to stay in use
  • Tell us your opening times and when work is allowed

Getting a fixed quote

How we handle washroom sealing in South Stour

Not every silicone belongs in a washroom. Sanitary grades carry anti-mould additives, 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 resealing that didn’t last because the old bead stayed and open joints along basins and vanity units, on kitchens and tea points, IPS panels and cubicles and accessible toilets and changing rooms. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in South Stour it comes down to the same thing: the right product in a properly prepared joint.

Halls and community buildings near places like South Stour are used by different groups through the week, and their toilets and kitchens show it. Resealing sinks, worktops and WCs with anti-mould silicone keeps them clean and watertight.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

What sealant work can’t fix

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Mould caused by poor ventilation, which will return until the extract is fixed
  • Water from plumbing, not from a joint
  • Panel boards already damaged by water

Not sure which it is? You can call 01277 525 020 or email drawings and photos and we will tell you honestly before you book.

Surfaces we seal

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

Quoting for work in South Stour

Each job is priced on its own details. The main factors are:

  • The site’s rules and procedures
  • Backing rod, priming and other preparation
  • Location, for remote and island sites
  • The product specified

A quote for washrooms and wet areas depends on how many there are, their condition and the access, plus any specification you’re working to. Ask us for a fixed quote.

Details that help us quote

A few photographs plus some basic facts will normally do. It helps to include:

  • The product your specification calls for
  • When you need the work done
  • Whether the building will be occupied during the work
  • The postcode of the building

Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to phone 01277 525 020 or send photos by email with what you know.

Keeping South Stour washrooms open while we work

South Stour lies roughly 51 miles out from central London, within the office belt around the capital. Office washrooms on business parks see heavy weekday use, which is why the work is phased.

At a school such as Finberry Primary School, changing rooms and kitchens need cleanable joints as much as the toilets. For a college such as Ashford College (3 miles north-west of South Stour), half-term and summer give the windows for washroom work. At a hospital like William Harvey Hospital (Ashford), which lies north of South Stour, patient and staff washrooms are best done in short phases agreed with the ward.

South Stour is about 3 miles south-east of Ashford, in Kent. Businesses, contractors and managing agents in South Stour use us for work on washrooms and wet areas, as part of our coverage of Kent. South Stour is one of 931 places we cover in Kent for washrooms and wet areas. There’s a separate page for Brighton, about 49 miles away.

Questions about South Stour

Can work at a site such as Ashford College fit around teaching?

Yes, holiday working periods are the norm on campus jobs. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Is a smaller place like South Stour outside your area?

No. Places such as South Stour are covered as much as the big towns. We work across Greater London and the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Do you offer coloured sealant?

In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.

Are you CHAS accredited?

Yes. We’re CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.

Can you follow the specification on our project?

Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it.

What happens if old sealant might contain asbestos?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.

Can weather delay the job?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

What happens if it’s left?

A failed joint behind a basin or along a shower tray lets water run where it shouldn’t. That can lead to swollen boards, marked ceilings below and lingering smells, and fixing that takes far more work than resealing. Older rural buildings around South Stour move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

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 rules also count.

What you get with us

  • Standard and matched colours in many product ranges
  • Over 20 years of commercial sealing

What the job involves on each surface

Healthcare and care settings

Clinics, hospitals and care homes need joints that can be kept clean. We work to your estates and infection-control requirements and any permits the site uses.

IPS and cubicle panels

Panel systems meet walls, floors and vanity tops at sealed joints. They stop water reaching the panel boards.

Doing it in-house

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

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