Washroom sealing in South Chingford

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

Keeping South Chingford washrooms open while we work

In London buildings, toilets and showers generally need to stay partly open, so we take one block of facilities out of use at a time. The 2 miles around South Chingford include 12 care or nursing homes. Care home wet rooms and en suites are used every day and cleaned hard, which tells on the silicone. Each room is kept out of use only as long as the sealant needs.

Colleges such as Sir George Monoux College (to the south-east of South Chingford) have toilets, changing rooms and catering kitchens that can be resealed around term dates. Church halls and community buildings, such as those at St Edmund's Church, have kitchens and toilets used by many groups, and their sanitary sealant works hard.

Washroom sealing in South Chingford, done properly

We reseal washrooms and wet areas in offices, hotels, schools, universities, gyms, healthcare buildings and care homes, plus the kitchens and tea points that go with them. The products and the method are chosen for how heavily each space is used. We work on vanity units and basins, showers, trays and wet room floors and accessible toilets and changing rooms, and the usual reasons a site gets in touch are sealant stained black around basins and showers and kitchen worktop joints that can’t be kept clean. Whether you call it commercial sealant work, mastic application or joint sealing, the work in South Chingford is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Many London buildings can’t close every toilet at once. Washrooms are done core by core or floor by floor, with signage and a plan agreed beforehand.

A 12-month guarantee applies to all our work in Greater London. If an installation problem shows up, ring 01277 525 020 or email a schedule or drawings and we’ll arrange a return visit.

Keeping the joints sound

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Don’t leave an open joint at a basin or tray
  • Respect the cure time before reopening each room
  • Mention any site permits or estates rules at quote stage
  • Inspect washroom sealant regularly

Ventilation is half the battle. Constant damp lets mould take hold even on anti-mould grades so report fans that aren’t working to your building services team.

Inspectors look at whether kitchen surfaces can be kept clean. Resealing sinks, worktops and splashbacks before an inspection is a simple step.

Signs you need washroom sealing in South Chingford

Occasionally a joint keeps failing because of a problem behind it: a loose panel, a leaking waste or water coming through the wall. We look for it before resealing and say if it needs a plumber or another trade.

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

  • Black mould inside silicone joints that cleaning can’t shift
  • Stained sealant around pans and urinals
  • Sealant lifting along a tray edge
  • Washrooms that look worn because of the sealant

Halls of residence and teaching buildings at universities such as University of Portsmouth Walthamstow Campus, 2 miles south of South Chingford, are easiest to reseal during vacations.

How to choose a sealant contractor

When it isn’t the sealant

Honesty saves time and money. Fresh joints won’t solve:

  • Vanity carcasses that have swollen
  • Water from plumbing, not from a joint
  • Fittings that move too much to hold a bead

If you are not sure, just give us a call on 01277 525 020 or send photos by email and we will give you a straight answer.

What we seal

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

Common questions from South Chingford clients

Can work in a care setting near South Chingford go ahead while residents are there?

Yes. We work around residents’ routines, a room or two at a time. We follow the home’s own procedures throughout.

Can you cope with the access rules in a London building?

Yes, we plan every London job around the building’s own access rules. Send the building rules and access times with your enquiry. The ULEZ covers the whole of Greater London, which we allow for

Do you offer coloured sealant?

In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.

What guarantee comes with washroom resealing?

There is a 12-month guarantee on our workmanship backed by public liability insurance.

How long will the new sealant 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.

How soon can the area be used again?

We will confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.

Are you insured?

Yes. We are fully insured, including public liability cover.

Surface by surface

IPS and cubicle panels

Cubicle and IPS panels move when leaned on or knocked so the bead needs to cope with it. We check fixings before sealing.

Urinals and WC pans

Floor joints around WC pans are often forgotten. They are checked with everything else.

How a job runs

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. In South Chingford, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.

  1. Every room is surveyed and the failed joints listed.
  2. You get a fixed quote with the phasing plan.
  3. Old sealant is removed completely and the faces cleaned.
  4. Each joint is cleaned and left dry.
  5. New anti-mould sealant goes in and is tooled neat.
  6. Rooms reopen after the cure time.

Getting the site ready

  • Confirm the product named in the specification
  • Warn occupants and staff about the work
  • Tell us what induction or permit system the site runs
