Common questions from Woolbridge clients

Is Woolbridge off your patch?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Must every washroom in our Woolbridge building shut while you work?

Rarely all at once: work is phased so some facilities are always available. Sanitary silicone needs time to cure before the area is used, and we will tell you how long for the product used.

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

We strip every bit of the failed bead and wipe away the residue before resealing. That’s what makes the new joint last.

Is colour matching possible?

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

How do we ask for a quote?

The quote form is the simplest route, though you can also phone 01277 525 020 or email drawings and photos. Include photographs or drawings if you have them.

Are your applicators CSCS-carded?

Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.

How much does the work cost?

Every job gets its own fixed quote. For yours, phone 01277 525 020 or use the quote form with a description of the work.

Washroom sealing in Woolbridge

In a commercial washroom, sealant is normally the first thing to wear out. Basin tops, urinal backs, panel joints and shower trays put it under water, chemicals and daily cleaning and mould that roots into it can’t be cleaned away. The fix is to remove it completely and reseal with sanitary silicone containing anti-mould additives. We work on showers, trays and wet room floors, urinals and WCs and vanity units and basins, and the usual reasons a site gets in touch are failed sealant behind washroom basins and panel joints letting water behind. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Woolbridge, preparation and product choice get the time they need.

In and around smaller places like Woolbridge, washroom work is often in halls, pubs, primary schools, care homes and holiday accommodation. Mould gets into sealant in any washroom that doesn’t dry out, and once it’s in, the sealant is replaced.

What our 12-month guarantee covers is the way we did the job: 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.

From enquiry to sign-off

At the end of each section, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. Jobs in and around smaller places like Woolbridge are usually planned as a single visit, so photos and measurements up front really help. That way the right products come on the day.

  1. Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
  2. We agree which rooms close and when, so users always have somewhere to go.
  3. Failed silicone is removed completely and the surfaces cleaned of every trace.
  4. Joints are cleaned, degreased and dried before sealing.
  5. A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
  6. Each room is handed back once the sealant has had its cure time.

What we need from you

  • Make sure the joints can be reached
  • Tell us what induction or permit system the site runs
  • Arrange parking or a loading space

Ask for a quote

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, call the office on 01277 525 020 or use the quote form.

Honest limits

Sealant solves a lot, but not everything, and we’re upfront when that’s the case. It won’t fix:

  • Panel boards already damaged by water
  • Leaking pipes, traps, wastes or cisterns, which need a plumber
  • Fittings that move too much to hold a bead

If you are not sure, just call the office on 01277 525 020 or email us and we’ll give you a straight answer before you book.

What we seal

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

Site staff or a sealant specialist?

Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Maintenance after handover

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Don’t leave an open joint at a basin or tray
  • Report faulty extraction promptly
  • Keep a record of which washrooms need attention
  • Tell us about infection-control or permit rules before we quote

Ventilation is half the battle. Constant damp lets mould take hold even on anti-mould grades, so get faulty extract looked at.

Small numbers of failed joints are quick to phase in. Left until every washroom is affected, it becomes a bigger programme and more closures to manage.

Keeping Woolbridge washrooms open while we work

Woolbridge lies roughly 36 miles out from central London, within the office belt around the capital. Office washrooms on business parks see heavy weekday use, which is why the work is phased.

At a hospital like Crowborough War Memorial Hospital, which lies north-west of Woolbridge, patient and staff washrooms are best done in short phases agreed with the ward. Where you are responsible for a hall attached to a building such as Church of St. Dunstan, its kitchen and toilets need sealant that stays cleanable.

Woolbridge is about 4 miles south-east of Crowborough, in East Sussex. Businesses, contractors and managing agents in Woolbridge use us for work on washrooms and wet areas, as part of our coverage of East Sussex. We work across 308 places in East Sussex. There’s a separate page for Brighton, about 20 miles away.

We also cover Wellbrook (1 mile south-east), Butcher's Cross (1 mile south-west), Mayfield (1 mile east), Skippers Hill (1 mile south-west) and Argos Hill (1 mile north).

What affects the price in Woolbridge

The price varies from site to site. It mainly depends on:

  • Distance, for remote addresses
  • How accessible the joints are
  • The total length or number of joints
  • Backing rod, priming and other preparation

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote and we’ll explain how it’s made up.

Before you send an enquiry

However big the job, the same details help:

  • Asbestos survey details if the building is older
  • Whether the building will be occupied during the work
  • The postcode of the building
  • Any specification or named product

A handful of photos and a postcode is the fastest way to a quote. Upload them with the quote form, or call the office on 01277 525 020 or email us if you’d rather talk the job through.

When to call us in Woolbridge

Mop buckets, trolleys and knocks from users damage joints near the floor, especially at floor edges and around urinals and WC pans.

Most enquiries start with one or more of the following:

  • Failed sealant in a tea point or staff kitchen
  • Open joints at the base of cubicle panels
  • Black mould inside silicone joints that cleaning can’t shift
  • Failed sealant behind washroom basins

At a school such as Mayfield Church of England Primary School, changing rooms and kitchens need cleanable joints as much as the toilets.

Before you book anyone

  • The terms of the workmanship guarantee
  • Who will actually carry out the work
  • Is the sealant right for the movement and the substrate?
  • What level of public liability insurance do they hold?
