Washroom sealing in Northbridge Street

In a busy washroom, the sealant usually gives up long before the tiles or fittings. Basin tops, urinal backs, panel joints and shower trays put it under water, chemicals and daily cleaning, and once mould grows into it, it can’t be scrubbed out. The fix is to remove it completely and reseal with sanitary silicone containing anti-mould additives. We work on IPS panels and cubicles, accessible toilets and changing rooms and kitchens and tea points, and what we’re called in for most is sealant stained black around basins and showers and discoloured joints around urinals and WC pans. For commercial sealant work in Northbridge Street, you deal with one contact from quote to sign-off, whether it’s one building or several.

Halls and community buildings near places like Northbridge Street 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.

A 12-month guarantee applies to all our work in East Sussex. Should something we installed fail, speak to us on 01277 525 020 or use the quote form and we’ll come back to it.

What the job involves on each surface

Wet-room floors and floor-to-wall joints

Wet-room floors and the joints where flooring turns up the wall need to stay sound. Floor perimeters and sealant joints near drains are resealed.

Basins and vanity tops

Natural stone tops can be marked by acetoxy silicone and we choose a neutral-cure grade for them.

Sanitary sealant for Northbridge Street buildings

At about 43 miles from central London, Northbridge Street is within reach of the capital, within the office belt around the capital. Business park offices have washrooms in daily use by staff, and resealing in phases keeps facilities available.

Office washrooms on sites such as Bodiam Business Park, 1.9 miles to the east of Northbridge Street, are in use all working day, so resealing is phased to keep some open. Hotels such as The Ostrich Hotel, 0.7 miles to the south-west of Northbridge Street, have en suite bathrooms where tired silicone at the bath, tray and basin is replaced room by room.

Northbridge Street is about 9 miles north-west of Hastings, in East Sussex. Northbridge Street sits inside our coverage and the rest of East Sussex, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Northbridge Street is one of 308 places we cover in East Sussex. There’s a separate page for Brighton, about 29 miles away.

Northbridge Street: questions and answers

Is Northbridge Street off your patch?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

Would you work within a site like Ticehurst House Hospital?

Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.

Do you offer coloured sealant?

Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.

Is it OK to put new silicone on top of the old?

We always remove it. Fresh silicone can’t key to an old bead, so sealing over it soon peels.

What about RAMS and site documents?

Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.

Is there a guarantee on the work?

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

What if there’s asbestos in the old mastic?

Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.

Do you need washroom sealing in Northbridge Street?

Washrooms are warm, damp and full of organic residue, and sealant joints trap all three. Even anti-mould grades can be colonised over time where extraction is poor.

Look out for the following:

  • Failed sealant in a tea point or staff kitchen
  • Black mould inside silicone joints that cleaning can’t shift
  • A new bead over an old one coming away
  • Urinal joints that look unhygienic

Schools such as Salehurst Church of England Primary School have toilets, changing rooms and kitchens that are best resealed in the holidays.

What to look for in a quote

  • What site paperwork they can supply
  • Who will actually carry out the work
  • Will failed sealant be removed rather than covered?
  • What the guarantee covers, and for how long

Our contractor checklist

Aftercare for building managers

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

  • Don’t leave an open joint at a basin or tray
  • Clean sealant with gentle products and a soft cloth
  • Keep washrooms out of use until we say the sealant has cured
  • Photograph and log failed joints across the estate

Each room goes back into use only when the sealant has cured enough. We’ll tell you when the wet areas can be used and signage stays in place until that time.

In food areas, cleanability is something environmental health officers look at. Resealing sinks, worktops and splashbacks before an inspection is a simple step.

When something else is needed

Some faults sit outside our scope, and we point that out rather than sealing over them:

  • Loose panels, vanity units or tiles, which need fixing first
  • Leaks through tanking or membranes below the finishes
  • Condensation from failed extract fans

If in doubt, phone 01277 525 020 or email us and we’ll say what we think.

Joints and surfaces we work on

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

Commercial clients in Northbridge Street

We work for building owners and managing agents on sealant work across single buildings or whole portfolios. One quote can cover more than one site, so there’s one set of paperwork to deal with.

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

Our process

When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself normally taking a morning or so for a small washroom, longer where showers and changing rooms are included. Jobs in and around smaller places like Northbridge Street are typically planned as a single visit, so photos and measurements up front really help. That way the right products come on the day.

  1. We inspect each washroom and record the joints to be resealed.
  2. The fixed quote sets out the rooms, the products and the phasing.
  3. The whole of the old bead is removed.
  4. Joints are degreased and dried.
  5. A sanitary silicone bead is laid and given a smooth tooled finish.
  6. Each area is handed back when ready.

What we need from you

  • Arrange parking or a loading space
  • Tell us what induction or permit system the site runs
  • Have the specification and drawings to hand
