About our washroom sealing in Great Chart

Since 2005 we have resealed commercial washrooms for facilities teams, contractors and building owners. We are CHAS accredited and a Constructionline member, with CSCS-carded applicators. We are fully insured. Every resealed washroom carries our 12-month guarantee. If you’re dealing with stained or open joints at kitchen sinks and worktops and sealant laid over old silicone and now peeling, we can put it right, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Great Chart is the same: the right product in a properly prepared joint.

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

The 12-month guarantee covers our workmanship: 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.

Different surfaces, different methods

Basins and vanity tops

Basin joints get wet every time someone washes their hands, so the wall joint and bowl surrounds tend to fail before anything else. We remove the old bead and lay a fresh one of sanitary silicone.

Healthcare and care settings

In healthcare, sealed joints are part of infection control. Your infection-control and estates rules are followed as well as site permits.

What we’re called out for in Great Chart

Washrooms are warm, damp and full of organic residue, and sealant joints trap all three. Anti-mould additives help, but in a poorly ventilated room mould can still take hold eventually.

Clients usually get in touch after noticing one or more of the following:

  • Failed joints along IPS and cubicle panels
  • Failed sealant behind washroom basins
  • Complaints from staff, guests or users about tired washrooms
  • Split or peeling sealant at shower trays

Where you’re responsible for a hall attached to a building such as Church of St Mary, its kitchen and toilets need sealant that stays cleanable.

Questions to ask before you book

  • How the joint faces will be prepared and primed
  • Will CSCS-carded applicators be on site?
  • Whether old or failed sealant will be cut out, not overlaid
  • How long is the guarantee, and what does it include?

How to choose a sealant contractor

Maintenance after handover

Keep the joints in good shape with a few simple steps:

  • Leave signs up until the cure time is over
  • Note failing joints building by building
  • Brief cleaning staff to treat joints gently
  • Inspect washroom sealant regularly

Squeegeeing showers and trays after heavy use helps. Standing water on a joint all day shortens its life.

Water getting behind IPS panels and vanity units can swell the boards. Once that happens, a reseal won’t fix them.

Why it’s worth doing now in Great Chart

Washrooms shape how visitors judge a building. Guests, clients, pupils and patients notice stained joints even when the room is otherwise spotless. Resealing is a modest task with a very visible payoff. For buildings around smaller places like Great Chart, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Why us?

  • Old sealant cut out, never sealed over
  • A Constructionline member, so easy to vet
  • A fixed quote before work starts
  • Work carried out by CSCS-carded applicators

When it isn’t the sealant

Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be any of the following:

  • Vanity carcasses that have swollen
  • Failed tanking beneath a wet-room floor or behind tiles
  • A room that stays damp because ventilation isn’t working

If in doubt, phone 01277 525 020 or send details through our quote form and we’ll say what we think before you book.

Joints and surfaces we work on

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

On site: what to expect

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Smaller jobs around Great Chart 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. Leaks, loose panels or damp are pointed out first.
  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.

Before we start on site

  • Tell us which areas need to stay in use
  • Clear stock, furniture or equipment away from the joints
  • Warn occupants and staff about the work
