Washroom sealing in Jericho

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Building owners, agents and FMs in Jericho

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Jericho can sit alongside others in a wider programme.

For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.

Washroom sealing in Jericho

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 vanity units and basins, showers, trays and wet room floors and kitchens and tea points, and the failures we’re asked to look at most are failed sealant in a tea point or staff kitchen and split or peeling sealant at shower trays. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Jericho it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

In a smaller place such as Jericho, commercial washrooms tend to be in schools, pubs, cafés, surgeries, care homes and sports clubs. However small, each needs the old sealant removed completely and anti-mould sanitary silicone applied to clean, dry joints.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Looking after the joints

Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Don’t leave an open joint at a basin or tray
  • Note failing joints building by building
  • Tell us about infection-control or permit rules before we quote
  • Make sure washroom ventilation is running

Include sealant joints in your planned maintenance checks. Check for mould spots, splits, lifting edges and open joints at trays, basins and urinals and photograph anything new.

Boards behind panels and vanity tops can swell when water gets past a failed joint. Once that happens, a reseal won’t fix them.

Different surfaces, different methods

Healthcare and care settings

In healthcare, sealed joints are part of infection control. We work to your estates and infection-control requirements and any permits the site uses.

Kitchens and tea points

Kitchen work can be phased around service. Tell us your site hours and access windows and we will plan around them.

How the quote is worked out

These are the things that shape the price:

  • Access and working height
  • Which sealant the job calls for
  • How much there is to seal
  • Travel to remote or island sites

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

Details that help us quote

Whether it’s one area or a whole building, these details speed things up:

  • Anything awkward about access or site hours
  • Drawings or a marked-up plan, if available
  • Asbestos survey details if the building is older
  • When you need the work done

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. For smaller jobs, photos and a description will do.

Why it’s worth doing now in Jericho

Water gets behind panels and under floors through a failed joint. That can lead to swollen boards, marked ceilings below and lingering smells which costs more to fix than a reseal. In a smaller place such as Jericho, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Why us?

  • 12 months’ guarantee on every job
  • CHAS accredited contractor
  • A fixed quote before work starts
  • Specification-led, product-correct work

On site: what to expect

Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then reopened once the sealant allows before the next one starts. Several jobs near Jericho can be grouped on one trip. Tell us your site hours and we will plan around them.

  1. We agree which washrooms close and when.
  2. Anything behind the joints that needs another trade is flagged.
  3. Old sealant is stripped and the faces prepared.
  4. We reseal with the grade suited to each area.
  5. We give you a reopening time for every room.

Before we start on site

  • Share the asbestos register for older buildings
  • Let building users know which areas are affected
  • Tell us your opening times and when work is allowed

Questions we are asked in Jericho

Is Jericho too far out for you?

Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Will our hotel in Jericho need to close for the work?

Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. Housekeeping and our team agree each day’s rooms.

Does weather matter for sealant work?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

Can you reseal washrooms in healthcare buildings?

We work in clinics, hospitals and care homes. Tell us what records you need and we will confirm with the quote.

What about RAMS and site documents?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.

Do you take on small jobs?

We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.

Can you follow the specification on our project?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.

Sanitary sealant for Jericho buildings

Jericho lies roughly 53 miles out from central London, within the office belt around the capital. Office toilets in the commuter belt are in use from first arrivals to last departures, so we phase work to keep some facilities open. A 2-mile radius around Jericho takes in a good number of hotels. Each has en suites, back-of-house toilets and kitchens with sealant that moulds and splits.

At a college such as City of Oxford College, 0.7 miles to the south of Jericho, washroom and kitchen sealant is best renewed in the holidays or in phases during term. For buildings on a site such as Littlemead Business Park (0.8 miles south-west of Jericho), washrooms and tea points can be resealed in phases through the working week. Customer toilets in retail centres such as Clarendon Shopping Centre (0.7 miles south-east of Jericho) rarely close, so resealing is phased.
