Need washroom sealing in Furzedown?

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

On site: what to expect

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. All of Greater London is in the ULEZ, and kerbside space in Furzedown can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.

  1. First, the phasing is agreed so facilities stay open.
  2. Anything behind the joints that needs another trade is flagged.
  3. Old sealant is stripped and the faces prepared.
  4. The right sanitary or food-safe sealant is applied.
  5. We give you a reopening time for every room.

What we need from you

  • Have the specification and drawings to hand
  • Tell us which areas need to stay in use
  • For older buildings, check the asbestos register before work

Getting a fixed quote

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, call the office on 01277 525 020 or email us.

How we handle washroom sealing in Furzedown

Accessible toilets, shower rooms and changing rooms have joints that work harder than most: shower trays, wet-room floor edges, basins and floor-to-wall junctions. An open joint there lets water track under flooring or behind wall panels so they get particular attention. We work on urinals and WCs, kitchens and tea points and showers, trays and wet room floors, and the failures we’re asked to look at most are urinal joints that look unhygienic and panel joints letting water behind. Searching for sealant specialists in Furzedown? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.

Restaurants, cafés and hotel kitchens across London have joints at worktops, sinks and wall cladding that need to stay smooth and cleanable. Hygienic and anti-mould sanitary sealants are used where they suit, with food-safe products where food contact is possible.

Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

When to bring in a specialist

Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Some joints are best left to specialists: for instance 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.

Honest limits

Some faults sit outside our scope, and we say so rather than covering them up:

  • Failed tanking beneath a wet-room floor or behind tiles
  • Condensation from failed extract fans
  • Panel boards already damaged by water

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

Surfaces we seal

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

Leave it or put it right?

Waiting for a holiday closure can leave failing joints in place for a long time. With phasing, the work can go ahead while most facilities stay open. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.

Pricing washrooms and wet areas depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.

What the job involves on each surface

Urinals and WC pans

Pan and urinal joints face constant cleaning and splashing. Once they discolour or split, they hold odours and make the room look neglected.

Healthcare and care settings

Clinics, hospitals and care homes need joints that can be kept clean. Your infection-control and estates rules are followed as well as site permits.

Busy facilities in and around Furzedown

A London building with hundreds of occupants can’t lose every washroom for a day, so we take one block of facilities out of use at a time. Furzedown has a number of hotels close by, all within 2 miles. Each has en suites, back-of-house toilets and kitchens with sealant that moulds and splits. The work can go floor by floor, agreed with housekeeping.

Toilets at places like Priory Retail Park, 1.5 miles to the south-west of Furzedown, are cleaned constantly, so silicone needs to be sound and smooth. For an occupier at a site such as Mitcham Industrial Estate, 0.8 miles south of Furzedown, the canteen and welfare facilities need cleanable joints as much as any office. Clinical washrooms at sites like St George's Hospital (1.2 miles west of Furzedown) are scheduled with the ward so the room is out of use for as little time as possible.

Furzedown is about 3 miles east of Wimbledon, in Greater London. Anywhere in SW16, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed.

Furzedown: questions and answers

Will our hotel in Furzedown 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.

Can work in a care setting near Furzedown go ahead while residents are there?

Yes. Care settings are planned area by area, at times agreed with the home. Noise and disruption are kept to a minimum.

Is colour matching possible?

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’ll confirm the colours available for the specified product.

Do you have public liability insurance?

Yes. We are fully insured, and the certificate can go with your quote.

Do you need to see the site first?

Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we will arrange a visit.

Which sealant will you use?

A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

How soon can the area be used again?

We’ll confirm how long the chosen product needs to cure, and sign any area that should be left alone.

After the work

Keep the joints in good shape with a few simple steps:

  • Photograph and log failed joints across the estate
  • Mention any site permits or estates rules at quote stage
  • Keep extract fans working and vents clear
  • Don’t leave trays and floors sitting wet

Where possible, have shower floors and trays squeegeed after busy periods. Joints that sit wet for hours fail sooner.

A split joint at a shower tray can leak for a long time before anyone sees it. By then, other trades may be needed as well, so reseal when you first spot a split.
