Questions we’re asked in Luxted

Do you work in London buildings with loading restrictions?

Yes, most London buildings have access rules of some kind, and we plan around them. The building manager’s rules go straight into our method. All of Greater London is inside the ULEZ, and our planning allows for it

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

Not all at once. We take one block of facilities at a time. Each area is handed back once the sealant has cured enough to use.

What happens if old sealant might contain asbestos?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.

Are you CHAS accredited and on Constructionline?

Yes. We are CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.

Do you do washroom sealing in healthcare settings?

Yes, healthcare and care settings are part of our work. Any records you need are confirmed with the quote.

Can you quote from photographs?

It depends on the job. Straightforward work can often be priced from photos and measurements, and bigger or more complex jobs usually get a visit.

How do you choose the sealant?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Washroom sealing in Luxted

In a busy washroom, the sealant typically gives up long before the tiles or fittings. Around basins, urinals, cubicles, IPS panels and shower trays it takes water, soap, cleaning chemicals and knocks every day, 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. If you have failed joints along IPS and cubicle panels and users noticing mouldy joints, we can put it right, on showers, trays and wet room floors, vanity units and basins and kitchens and tea points alike. Whether you call it commercial sealant work, mastic application or joint sealing, in Luxted it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

In a London area such as Luxted, 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.

Work we carry out in Greater London comes with a 12-month guarantee. If an installation problem shows up, phone 01277 525 020 or email us and we will arrange a return visit.

What happens if it’s left?

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. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Diagnose, treat, sign off

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes a few hours for one toilet block, with bigger buildings phased across a number of visits, and we clear our waste as we work. All of Greater London is in the ULEZ, and kerbside space in Luxted can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.

  1. We survey each room, count the joints and note anything behind them that needs another trade.
  2. The phasing is agreed so there are always facilities open.
  3. The failed silicone is stripped and every face scraped clean of residue.
  4. We clean and dry every surface so the new sealant can grip.
  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

  • Agree which areas must stay open
  • Make sure the joints can be reached
  • Share the asbestos register for older buildings

Toilets, showers and kitchens around Luxted

In London buildings, toilets and showers generally need to stay partly open, so we phase the work core by core or floor by floor with the building manager.

Units at estates like Biggin Hill Airport Trading Estate (1 mile west of Luxted) have welfare blocks whose showers and toilets see shift after shift. En suites at hotels like The Landing Hotel, 1.1 miles to the west of Luxted, are cleaned daily, which wears silicone over time.

Luxted is about 5 miles south-west of Orpington, in Greater London. We cover Luxted and the rest of Greater London, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. We work across 764 places in Greater London, large and small. We also cover London, some 14 miles away.

Keeping the joints sound

After handover, these steps help:

  • Keep a record of which washrooms need attention
  • Add sealant joints to planned maintenance checks
  • Make sure washroom ventilation is running
  • Respect the cure time before reopening each room

Squeegeeing showers and trays after heavy use helps. Joints that sit wet for hours fail sooner.

Inspectors look at whether kitchen surfaces can be kept clean. Failed sealant around sinks and worktops is easy to put right in good time.

Different surfaces, different methods

Showers and trays

Shower trays move under foot and are wet all day. Tray joints are where many washroom leaks start.

Kitchens and tea points

We plan kitchen sealing around when the kitchen is in use. Your site hours and access windows set the timing.

When to call us in Luxted

Low-level joints get hit by mop buckets, cleaning trolleys and feet at skirting lines, urinal bases and around pans.

Any of the following is a good reason to get the joints checked over:

  • Stained or open joints at kitchen sinks and worktops
  • Urinal joints that look unhygienic
  • Mould spotting along silicone joints
  • Failed sealant behind washroom basins

At a hospital like Princess Royal University Hospital, 2.9 miles to the north of Luxted, patient and staff washrooms are best done in short phases agreed with the ward.

What your quote should include

  • Can the work be phased to keep areas open?
  • Whether old or failed sealant will be cut out, not overlaid
  • How long is the guarantee, and what does it include?
  • Will RAMS and insurance details be available?

Questions to ask before you appoint anyone

Site staff or a sealant specialist?

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 easy to get wrong without experience.

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
