Washroom sealing in Redbridge, done properly

When mould has spotted a silicone joint, more cleaning won’t remove it. The growth is inside the sealant, which is why it comes back however often it is treated. Replacing the bead is the lasting treatment. We work on accessible toilets and changing rooms, urinals and WCs and kitchens and tea points, and the usual reasons a site gets in touch are discoloured joints around urinals and WC pans and split or peeling sealant at shower trays. A single leaking joint is often how a building in Redbridge first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Smaller places such as Redbridge still have commercial washrooms and kitchens: in halls, pubs, schools, care homes and farm-based businesses. Sealant that has gone black with mould normally can’t be cleaned, so it is cut out and replaced.

We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant.

Work for main contractors and building owners

Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.

We work for building owners and managing agents on sealant work across single buildings or whole portfolios. Several sites can go on one quote, so there’s one set of paperwork to deal with.

Our process

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work typically takes a morning or so for a small washroom, longer where showers and changing rooms are included, and we clear our waste as we work. Rural sites near Redbridge may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.

  1. We agree which washrooms close and when.
  2. Anything behind the joints that needs another trade is flagged.
  3. Failed sealant and residue are stripped out.
  4. The right sanitary or food-safe sealant is applied.
  5. We give you a reopening time for every room.

What we need from you

  • Tell us which areas need to stay in use
  • Share the asbestos register for older buildings
  • Move anything stored against the joints

Request a quote

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. For smaller jobs, photographs and a description will do.

Related advice

Do you need washroom sealing in Redbridge?

We often find acrylic caulk or general-purpose sealant in joints that should have sanitary silicone. They don’t stand up to constant water and they discolour and fail early.

Most enquiries start with something like this:

  • Failed joints along IPS and cubicle panels
  • Open joints along basins and vanity units
  • Shower tray joints that have opened up
  • Urinal joints that look unhygienic

Hotels such as Anchor Hotel, under half a mile to the north of Redbridge, have en suite bathrooms where tired silicone at the bath, tray and basin is replaced room by room.

What your quote should include

  • Do they follow the manufacturer’s priming guidance?
  • Whether their applicators hold CSCS cards
  • What level of public liability insurance do they hold?
  • Their pre-qualification and accreditations

How to choose a sealant contractor

What we can’t put right

A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be one of these:

  • Leaks through tanking or membranes below the finishes
  • Water from plumbing, not from a joint
  • Mould caused by poor ventilation, which will return until the extract is fixed

Not sure which it is? You can phone 01277 525 020 or use the quote form and we’ll tell you honestly before you book.

What we seal

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

Should maintenance staff do it?

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.

Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

FAQs: Redbridge

Is Redbridge too small for you to travel to?

No. Places such as Redbridge are covered as much as the big towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Do you work in occupied care homes around Redbridge?

Yes. We agree rooms and times with the manager and work a few areas at a time. We follow the home’s own procedures throughout.

Are you insured?

Yes. Our insurance certificate can be sent alongside the quote.

Is it possible to just clean mouldy silicone?

Surface cleaning won’t reach mould that has rooted into the bead. We replace the sealant with an anti-mould sanitary grade and point out if ventilation is part of the problem.

Are your applicators CSCS-carded?

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

How much does the work cost?

There isn’t a price list, as every site differs. With photos or drawings, we can give you a fixed quote.

Is there a guarantee on the work?

A 12-month guarantee covers the work. It covers our workmanship rather than damage, leaks from plumbing or ventilation problems.

Busy facilities in and around Redbridge

Redbridge lies within about 1 mile of the sea, and coastal places often have hotels, guest houses and holiday accommodation with busy seasons. Heavy seasonal use is hard on shower and basin sealant, so we plan the work for quieter weeks where possible. Redbridge has several hotels close by, all within 2 miles. Behind every hotel door there’s a bathroom whose sealant will need renewing sooner or later. The work can go floor by floor, agreed with housekeeping.

Healthcare washrooms on sites such as Western Community Hospital, 1.2 miles east of Redbridge, are resealed area by area, under the site’s own infection-control rules. Toilets at colleges like Totton College, 1.5 miles to the west of Redbridge, take heavy use from students and staff alike.

Redbridge is about 1 mile east of Totton, in Southampton. Our applicators travel to Redbridge for work on washrooms and wet areas. Across Southampton, 30 places are covered, including Redbridge.

We take on washrooms and wet areas across the SO40, SO16 and SO15 postcode area.

Nearby places we also cover include Eling (1 mile south-west), Millbrook (1 mile east), Hillyfields (1 mile north), Maybush (1 mile north-east) and Regents Park (1 mile east). Bigger towns within reach include Southampton (3 miles east), Midanbury (5 miles east), Thornhill (6 miles east), Harefield (6 miles east), Itchen (5 miles east) and Sholing (5 miles east).

Why deal with it now?

A failed joint behind a basin or along a shower tray lets water run where it shouldn’t. In a commercial building that can mean damaged boards, stained ceilings on the floor below and odours, and fixing that takes far more work than resealing. One visit to deal with every failing joint makes more sense than several trips to a place like Redbridge, rather than one at a time. Send photos of each area and we will quote for the lot.

The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Why clients in Redbridge choose us

  • Old sealant cut out, never sealed over
  • A range of standard colours, depending on the product
  • Commercial sealant work since 2005
