Washroom sealing for Cooper's Corner sites

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Washroom sealing in Cooper's Corner

Accessible toilets, shower rooms and changing rooms have joints that work harder than most: wet-floor edges, tray perimeters, basin tops and the line where flooring meets the wall. An open joint there lets water track under flooring or behind wall panels, so we look at them closely. We work on vanity units and basins, showers, trays and wet room floors and accessible toilets and changing rooms, and what we’re called in for most is a new bead over an old one coming away and failed sealant behind washroom basins. Looking for mastic applicators who cover Cooper's Corner? Mastic Doctor has worked for contractors, FMs and building owners since 2005.

Halls and community buildings near places like Cooper's Corner 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.

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.

How the job changes by surface

Basins and vanity tops

Vanity tops and basins are splashed all day, so the joint to the wall and around each bowl fails early. We remove the old bead and lay a fresh one of sanitary silicone.

Kitchens and tea points

Kitchen work can be phased around service. Tell us your site hours and access windows and we’ll plan around them.

Why deal with it now?

Water gets behind panels and under floors through a failed joint. That can lead to swollen boards, marked ceilings below and lingering smells, and fixing that takes far more work than resealing. Converted and older buildings near places like Cooper's Corner tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

Why clients in Cooper's Corner choose us

  • Matching to RAL references, product permitting
  • Old sealant cut out, never sealed over
  • Clear, fixed quotes
  • 12 months’ guarantee on every job

How a job runs

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. Jobs in and around smaller places like Cooper's Corner are typically planned as a single visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  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 give you a reopening time for every room.

Preparing the site

  • Point out any areas we must not close
  • Send any specification or drawings in advance
  • Clear stock, furniture or equipment away from the joints

Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. Smaller jobs need nothing more than photos and a few notes.

Washroom sealing in Cooper's Corner: the local picture

At about 41 miles from central London, Cooper's Corner is within reach of the capital, in a commuter belt where offices and business parks are common. Business park offices have washrooms in daily use by staff, so we phase work to keep some facilities open.

For a site such as Hawkhurst Community Hospital, 1.8 miles north-east of Cooper's Corner, sanitary joints in clinical areas need sound, cleanable sealant and a careful method. For a school such as Hurst Green Church of England Primary School and Nursery, washroom and kitchen sealant can be renewed around term dates. For buildings on a site such as Bodiam Business Park, which lies south-east of Cooper's Corner, washrooms and tea points can be resealed in phases through the working week.

When to bring in a specialist

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Honest limits

Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:

  • Leaks through tanking or membranes below the finishes
  • Swollen or delaminated boards behind panels or vanity tops
  • Fittings that move too much to hold a bead

Not sure which it is? You can ring 01277 525 020 or email a schedule or drawings and we’ll tell you honestly.

Surfaces we seal

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

Common questions from Cooper's Corner clients

Do you take on work at healthcare sites like Hawkhurst Community Hospital?

Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Will all the washrooms in our Cooper's Corner building be closed at once?

Normally only some of them, for a short time. We work in phases so other facilities stay open. Sanitary silicone needs time to cure before the area is used, and we’ll tell you how long for the product used.

Can you work to our specification?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.

Will your applicators have CSCS cards?

Yes. If you need card details for site access, let us know and we will send them with the quote.

Will all the toilets be closed at once?

We phase it so users always have somewhere to go. We work through the building a room or section at a time around your site hours and access windows.

Is there a guarantee on the work?

Our workmanship has a 12-month guarantee backed by public liability insurance.

Are you CHAS accredited and on Constructionline?

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