Washroom sealing near Stanford Rivers

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Why deal with it now?

Leaving the job until a shutdown often means living with it for months. Phasing lets it happen now, with facilities kept in use. Around Stanford Rivers, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Why us?

  • Sealing commercial buildings since 2005
  • CHAS accredited contractor
  • 12 months’ guarantee on every job
  • RAL and finish matching where the product range allows

About our washroom sealing in Stanford Rivers

Facilities managers, contractors and building owners have used us for washroom sealing for over 20 years. Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We are fully insured. Every resealed washroom carries our 12-month guarantee. Most enquiries involve washrooms that look worn because of the sealant and resealing that didn’t last because the old bead stayed, across accessible toilets and changing rooms, showers, trays and wet room floors and kitchens and tea points. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Stanford Rivers it comes down to the same thing: the right product in a properly prepared joint.

Community buildings around smaller places like Stanford Rivers have kitchens and toilets used by many people. Resealing sinks, worktops and WCs with anti-mould silicone keeps them clean and watertight.

We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

After the work

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

  • Add sealant joints to planned maintenance checks
  • Don’t leave an open joint at a basin or tray
  • Leave signs up until the cure time is over
  • Squeegee showers and trays after busy periods

Any failure in our workmanship within the 12-month guarantee is ours to put right. Beyond that, regular checks keep small problems small.

Leaks through tray and wet-floor joints can go unseen until a ceiling marks below. By then, other trades may be needed as well, so reseal when you first spot a split.

How the job changes by surface

Kitchens and tea points

Staff kitchens and tea points have joints at worktops, sinks and splashbacks. Sound joints keep those surfaces easy to clean.

Urinals and WC pans

Pan and urinal joints face constant cleaning and splashing. Stained or split joints here trap smells and look unhygienic.

When to call us in Stanford Rivers

Much of the failed sealant we remove was applied over old silicone or residue. New silicone won’t grip the old, so it soon lets go.

These are often picked up first by site or facilities staff:

  • Urinal joints that look unhygienic
  • Kitchen worktop joints that can’t be kept clean
  • Open joints along basins and vanity units
  • Split or peeling sealant at shower trays

At a school such as Chipping Ongar Primary School, changing rooms and kitchens need cleanable joints as much as the toilets.

What your quote should include

  • Their public liability cover
  • The terms of the workmanship guarantee
  • Who will actually carry out the work
  • How the existing material will be dealt with

Our contractor checklist

Honest limits

Before quoting, we check that sealant is the right answer. It won’t put right:

  • A room that stays damp because ventilation isn’t working
  • Fittings that move too much to hold a bead
  • Leaks through tanking or membranes below the finishes

Not sure which it is? You can ring 01277 525 020 or email the details over and we’ll tell you honestly before you book.

Where we work in Stanford Rivers

Questions we’re asked in Stanford Rivers

Will all the washrooms in our Stanford Rivers building be closed at once?

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 hospital work, at somewhere like Suttons Manor Hospital, something you do?

Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.

How long does a job like this take?

It depends on the scope, though a typical visit usually takes between a morning and a week or so, set by the number of rooms and the phasing you need. Larger or phased jobs take longer, and we will give you a timescale with the quote.

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.

Do you cover Stanford Rivers?

Yes. Stanford Rivers falls within our area, and you can call the office on 01277 525 020 or email drawings and photos to get started.

Do you have public liability insurance?

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

How long before the toilets can reopen?

Cure times vary by product and temperature. Each room gets its own reopening time from us, and signs stay up until then.

Central London is about 19 miles from Stanford Rivers, in a commuter belt where offices and business parks are common. Office washrooms on business parks see heavy weekday use, so we phase work to keep some facilities open.

Halls linked to places like Church of St Margaret of Antioch host groups all week, which is hard on kitchen and toilet sealant. Staff changing rooms and patient toilets at places like Suttons Manor Hospital (2.4 miles south-west of Stanford Rivers) need cleanable, sound silicone.

From enquiry to sign-off

Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Smaller jobs around Stanford Rivers can be grouped with others nearby. You’ll have a fixed quote before work starts.

  1. We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
  2. The phasing is agreed so there are always facilities open.
  3. Failed silicone is removed completely and the surfaces cleaned of every trace.
  4. Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
  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.

Preparing the site

  • Warn occupants and staff about the work
  • Move anything stored against the joints
  • Send any specification or drawings in advance
