Washroom sealing in East Mersea

When mould has spotted a silicone joint, more cleaning won’t remove it. The mould has rooted into the silicone itself so it returns whatever the cleaning regime. Replacing the bead is the lasting treatment. The enquiries we see most involve failed sealant behind washroom basins and sealant stained black around basins and showers, on IPS panels and cubicles, vanity units and basins and accessible toilets and changing rooms. Whoever orders the work in East Mersea, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Halls and community buildings near places like East Mersea 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.

Work we carry out comes with a 12-month guarantee. If an installation problem shows up, give us a call on 01277 525 020 or email the details over and we’ll arrange a return visit.

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. If others near East Mersea need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.

  1. Every room is surveyed and the failed joints listed.
  2. The fixed quote sets out the rooms, the products and the phasing.
  3. The whole of the old bead is removed.
  4. Each joint is cleaned and left dry.
  5. A sanitary silicone bead is laid and given a smooth tooled finish.
  6. Rooms reopen after the cure time.

What we need from you

  • Warn occupants and staff about the work
  • Tell us which areas need to stay in use
  • Point out parking and an unloading spot

Getting a fixed quote

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we will arrange a site visit if anything is unclear.

Related advice

After the work

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:

  • Tell us about infection-control or permit rules before we quote
  • Include joints in routine washroom inspections
  • Respect the cure time before reopening each room
  • Photograph and log failed joints across the estate

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

Mouldy sealant only gets harder to ignore, and complaints follow. Dealing with it while it’s just the sealant keeps it simple.

Questions we’re asked in East Mersea

Will the toilets in our East Mersea building be out of use?

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 will tell you how long for the product used.

Is East Mersea too small for you to travel to?

No. Places such as East Mersea are covered as much as the big towns. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.

How long do sealant joints last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

What happens if old sealant might contain asbestos?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.

How do you choose the sealant?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Do you take on multi-site work?

Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.

Is old silicone taken out first?

The whole of the old bead is removed and the surfaces cleaned first. It’s the difference between a joint that lasts and one that peels.

What we are called out for in East Mersea

Much of the failed sealant we remove was applied over old silicone or residue. Silicone won’t adhere to a silicone bead so it peels away quickly.

Site and facilities staff are often the first to spot these:

  • Split or peeling sealant at shower trays
  • A new bead over an old one coming away
  • Discoloured joints around urinals and WC pans
  • Sealant stained black around basins and showers

Where you are responsible for a hall attached to a building such as Parish Church of St Edmund King and Martyr, its kitchen and toilets need sealant that stays cleanable.

What to look for in a quote

  • How joint depth will be controlled
  • Will RAMS and insurance details be available?
  • Whether old or failed sealant will be cut out, not overlaid
  • Who will actually carry out the work

Our contractor checklist

Different surfaces, different methods

Changing rooms and gyms

Changing rooms can be phased so one stays open. Tell us your site hours and access windows and we’ll plan around them.

Kitchens and tea points

Staff kitchens and tea points have joints at worktops, sinks and splashbacks. Sound joints keep those surfaces easy to clean.

Leave it or put it right?

Water gets behind panels and under floors through a failed joint. In a commercial building that can mean damaged boards, stained ceilings on the floor below and odours which costs more to fix than a reseal. Converted and older buildings near places like East Mersea tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

Keeping East Mersea washrooms open while we work

With the shore within about 2 miles, East Mersea counts as a coastal location, and coastal places often have hotels, guest houses and holiday accommodation with busy seasons. Washrooms used guest after guest wear their sanitary silicone faster, so we plan the work for quieter weeks where possible. Central London is about 50 miles from East Mersea. Washrooms in commuter-belt offices take constant weekday traffic, which is why the work is phased.

Office washrooms on sites such as Waldegraves Business Park (to the south-west of East Mersea) are in use all working day, so resealing is phased to keep some open.
