How we handle washroom sealing in Temple

Not every silicone belongs in a washroom. Sanitary silicone contains additives that resist mould, and neutral-cure versions avoid the damage acetoxy types can do to some metals, stone and mirror backings. Where food contact is possible, we use a hygienic, food-safe grade. The enquiries we see most involve stained sealant around pans and urinals and shower tray joints that have opened up, across IPS panels and cubicles, accessible toilets and changing rooms and urinals and WCs. For commercial sealant work in Temple, you deal with one contact from quote to sign-off, whether it’s one building or several.

In a London area such as Temple, commercial washrooms in offices, hotels and leisure buildings see constant use. We cut out tired sealant around vanity units, cubicles, IPS panels and showers and lay fresh anti-mould sanitary silicone, a block of facilities at a time.

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’re clear about what is covered before work starts.

Different surfaces, different methods

Changing rooms and gyms

Gym and leisure changing rooms see showers running most of the day, so mould is a constant battle. Anti-mould sanitary silicone is the standard choice.

IPS and cubicle panels

Panels flex slightly in use, so the sealant has to take that movement. We check fixings before sealing.

Doing it in-house

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Why act early in Temple

Waiting for a holiday closure can leave failing joints in place for a long time. Phasing lets it happen now, with facilities kept in use. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.

A quote for washrooms and wet areas depends on how many there are, their condition and the access. Call for a quote.

Why appoint us

  • A fixed quote before work starts
  • Our applicators hold CSCS cards
  • Old sealant cut out, never sealed over
  • Colour options checked against the specified product

What we can’t put right

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:

  • Condensation from failed extract fans
  • Loose panels, vanity units or tiles, which need fixing first
  • Water from plumbing, not from a joint

If you are not sure, just phone 01277 525 020 or email us and we’ll give you a straight answer.

Surfaces we seal

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

What we are called out for in Temple

Panels and vanity units move slightly in use, and shower trays shift under foot. If the joint wasn’t laid to take that movement, it tears or peels away.

Most enquiries start with something like this:

  • Resealing that didn’t last because the old bead stayed
  • Washrooms that look worn because of the sealant
  • Stained or open joints at kitchen sinks and worktops
  • Open joints at the base of cubicle panels

For an occupier at a site such as Grand Vitesse Industrial Estate (0.7 miles south-east of Temple), the canteen and welfare facilities need cleanable joints as much as any office.

Questions to ask before you book

  • Health and safety accreditation such as CHAS
  • Whether their applicators hold CSCS cards
  • How they’ll work around occupants
  • Whether primer will be used where the manufacturer specifies it

How to choose a sealant contractor

Wet areas in Temple’s workplaces

A 2-mile radius around Temple takes in plenty of hotels. Hotel en suites take daily use, and tired silicone at trays and basins is one of the first things guests notice. We work a handful of rooms at a time, so the hotel keeps letting the rest. Busy London buildings need some toilets open at all times, so we phase the work core by core or floor by floor with the building manager.

In a centre such as Brunswick Centre, which lies north-west of Temple, public washrooms are resealed a block of facilities at a time. Colleges such as The Royal College of Radiologists, under half a mile to the north-west of Temple, have toilets, changing rooms and catering kitchens that can be resealed around term dates.

Temple is about 1 mile south of St Pancras, in City of London. We cover Temple and the rest of City of London, with the same fixed quotes and 12-month guarantee as everywhere else. Temple is one of 7 places in City of London on our list for washrooms and wet areas.

Business premises anywhere in SE1, WC2H and WC2B are within our area for washrooms and wet areas. Streets here include Shoe Lane, Drury Lane and New Square. Access to Temple is via the A4 and A40, so getting applicators and materials to site is simple. If your building is just outside Temple, we cover Temple Bar (1 mile north), Blackfriars (1 mile east), Aldwych (1 mile west), Clare Market (1 mile north-west) and Covent Garden (1 mile west).

Around Temple

We work on buildings around Mercers' School, The Devereux pub and Garden Bridge and the streets around them. Nearby too are British Library of Political and Economic Science (under half a mile north-west), St Mary-at-Hill (1.2 miles east) and London Nautical School (under half a mile south). There’s a railway station in Temple itself: London Blackfriars station. A little further out are Montfichet's Tower (under half a mile east) and St Philip's Hospital (less than half a mile north-west). Not far away are Barnsbury Wood and Ludgate Hill.

Diagnose, treat, sign off

In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then handed back before the next one starts. Planning a London job such as one in Temple starts with access: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.

  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. We strip out the old bead and clean off the residue left behind.
  4. Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
  5. New sanitary silicone with anti-mould additives goes in and is tooled neat.
  6. Each room is handed back once the sealant has had its cure time.

What we need from you

  • Share your working hours and any access restrictions
  • Point out any areas we must not close
  • Clear stock, furniture or equipment away from the joints

Questions about Temple

Does a hotel in Temple need to shut while its sealant is renewed?

In most cases no closure is needed: we work room by room or floor by floor. Tell us your quiet periods and access windows and we’ll plan around them.

Can you take on a job at a hospital such as St Bartholomew's Hospital?

Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.

Is old silicone taken out first?

We always remove it. New silicone won’t stick to the old so a bead over the top fails quickly.

What if there’s asbestos in the old mastic?

The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.

What guarantee comes with washroom resealing?

Every job carries our 12-month guarantee. It covers our workmanship rather than damage, leaks from plumbing or ventilation problems.

Which silicone is right for commercial washrooms?

It depends on the joint. Washrooms and showers take anti-mould sanitary silicone, and food areas take a hygienic, food-safe sealant where food contact is possible.

Can the sealant be colour-matched?

In many cases, 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.
