Clinical washrooms at sites like Midhurst Community Hospital, 4.1 miles south-east of Borden, are scheduled with the ward so the room is out of use for as little time as possible.

Washroom sealing in Borden

Accessible toilets, shower rooms and changing rooms have joints that work harder than most: shower trays, wet-room floor edges, basins and floor-to-wall junctions. An open joint there lets water track under flooring or behind wall panels, so we look at them closely. If you are dealing with sealant lifting along a tray edge and stained or open joints at kitchen sinks and worktops, we can put it right, whatever the surface. Most enquiries from Borden start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

Halls and community buildings near places like Borden are used by different groups through the week, and their toilets and kitchens show it. Fresh anti-mould sanitary silicone at sinks, worktops and toilets keeps them cleanable.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Diagnose, treat, sign off

Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. Smaller jobs around Borden can be grouped with others nearby, which keeps travel down. You’ll have a fixed quote before work starts.

  1. First, the phasing is agreed so facilities stay open.
  2. Anything behind the joints that needs another trade is flagged.
  3. Failed sealant and residue are stripped out.
  4. We reseal with the grade suited to each area.
  5. We confirm reopening times for each washroom.

Getting the site ready

  • Make sure the joints can be reached
  • Warn occupants and staff about the work
  • Tell us which areas need to stay in use

Getting a fixed quote

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Advice

Common problems we fix in Borden

A lot of failed washroom sealant was laid over an old bead or a dirty surface. New silicone won’t grip the old, so it soon lets go.

If one of these sounds familiar, it’s time for a closer look:

  • Stained sealant around pans and urinals
  • Users noticing mouldy joints
  • Open joints at the base of cubicle panels
  • A new bead over an old one coming away

Halls linked to places like Church of St Peter host groups all week, which is hard on kitchen and toilet sealant.

Our contractor checklist

Work for main contractors and building owners

CHAS accredited and a Constructionline member, we are straightforward to vet for your supplier list. We’re fully insured, and our insurance certificate can go with the quote.

Building owners and managing agents use us on sealant work across single buildings or whole portfolios around Borden. Several sites can go on one quote, which keeps the paperwork simple.

Looking after the joints

Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Avoid scourers and harsh descalers on silicone
  • Respect the cure time before reopening each room
  • Report split joints at trays and basins early
  • Note failing joints building by building

Mild cleaning products and non-abrasive cloths look after sanitary silicone best. Aggressive descalers, solvents and scouring pads shorten its life over time.

Inspectors look at whether kitchen surfaces can be kept clean. Failed sealant around sinks and worktops is easy to put right in good time.

When it isn’t the sealant

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

  • Vanity carcasses that have swollen
  • Hollow tiles or loose panels behind the joint
  • Leaking pipes, traps, wastes or cisterns, which need a plumber

If in doubt, give us a call on 01277 525 020 or email us and we’ll say what we think.

Joints and surfaces we work on

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

Questions we’re asked in Borden

Do we have to close all our washrooms in Borden 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 Borden off your patch?

Not at all. Borden is within our area. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Do you need to remove the old sealant?

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.

Do you guarantee washroom sealing?

Every job carries our 12-month guarantee. It applies to our workmanship, not to plumbing leaks or damp from poor ventilation.

Will you come and look before quoting?

Many jobs can be quoted from photos, drawings or a joint schedule. Where they aren’t, we arrange a site visit.

Can you send site paperwork?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.

How many days will you need on site?

The duration is planned around your programme and the access we are given. We will give you an estimate of time on site when we quote.

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 usually costs more in the end than doing them right.

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
