How we handle washroom sealing in Coleman's Hatch

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. Gaps in those places let water get under the floor or behind panels, so we look at them closely. We work on kitchens and tea points, urinals and WCs and accessible toilets and changing rooms, and the failures we’re asked to look at most are stained sealant around pans and urinals and mould spotting along silicone joints. Whether you call it commercial sealant work, mastic application or joint sealing, in Coleman's Hatch it comes down to the same thing: the right product in a properly prepared joint.

Community buildings around smaller places like Coleman's Hatch have kitchens and toilets used by many people. Resealing sinks, worktops and WCs with anti-mould silicone keeps them clean and watertight.

We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

General trades versus a 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.

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

Diagnose, treat, sign off

Tell us your site hours and access windows and we’ll plan around them. While we’re working, the area stays contained and tidy, and your contact hears from us before we move to the next area. Jobs in and around smaller places like Coleman's Hatch are normally planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. We inspect each washroom and record the joints to be resealed.
  2. You get a fixed quote with the phasing plan.
  3. The whole of the old bead is removed.
  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.

Before we start on site

  • Arrange parking or a loading space
  • Tell staff and tenants when we will be in
  • Send asbestos survey details if the building is pre-2000

Advice

When something else is needed

A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is any of the following:

  • Hollow tiles or loose panels behind the joint
  • A room that stays damp because ventilation isn’t working
  • A dripping waste or valve behind a panel

If in doubt, call the office on 01277 525 020 or use the quote form and we’ll say what we think before you book.

Where we work in Coleman's Hatch

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

Aftercare for building managers

Problems stay small when the joints are checked regularly. Specifically:

  • Add sealant joints to planned maintenance checks
  • Clean sealant with gentle products and a soft cloth
  • Don’t leave an open joint at a basin or tray
  • Keep a record of which washrooms need attention

Any failure in our workmanship within the 12-month guarantee is ours to put right. Beyond that, regular checks keep small problems small.

Boards behind panels and vanity tops can swell when water gets past a failed joint. Once that happens, a reseal won’t fix them.

When to call us in Coleman's Hatch

Panels and vanity units move slightly in use, and shower trays shift under foot. If the joint wasn’t laid to take that movement, it tears or peels away.

Typical triggers for a call:

  • Mould spotting along silicone joints
  • Failed sealant behind washroom basins
  • Resealing that didn’t last because the old bead stayed
  • Users noticing mouldy joints

For buildings on a site such as Forest Row Business Park, 1.5 miles north-west of Coleman's Hatch, washrooms and tea points can be resealed in phases through the working week.

What your quote should include

  • Who will actually carry out the work
  • Can the work be phased to keep areas open?
  • How joint depth will be controlled
  • Whether primer will be used where the manufacturer specifies it

What happens if it’s left?

Bleaching black sealant may lighten it for a few days but the growth is inside the bead and returns. Replacement deals with the cause in the joint and your cleaning team stops chasing it. Around Coleman's Hatch, it’s better to renew all the failing joints at once, rather than one at a time. Send photographs of each area and we’ll quote for the lot.

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

Questions we’re asked in Coleman's Hatch

Do we have to close all our washrooms in Coleman's Hatch for resealing?

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.

Can you take on a job at a hospital such as Queen Victoria Hospital?

Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Does the weather affect the work?

Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

What sealant do you use in washrooms?

An anti-mould sanitary silicone in most cases. Neutral-cure grades are used where acetoxy types could mark metals, stone or mirror backings.

Will cleaning remove black mould from sealant?

Typically not. Mould grows into the sealant itself, so it comes back however often it’s cleaned. Replacement is the lasting fix.

Do you hold CHAS accreditation?

Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.

Do you need to remove the old sealant?

We always remove it. New silicone won’t stick to the old, so sealing over it soon peels.
