How we handle washroom sealing in Wimbledon

Facilities managers, contractors and building owners have used us for washroom sealing for over 20 years. We are CHAS accredited and a Constructionline member, with CSCS-carded applicators. We are fully insured. Our workmanship is guaranteed for 12 months. Most enquiries involve failed sealant in a tea point or staff kitchen and shower tray joints that have opened up, across vanity units and basins, IPS panels and cubicles and showers, trays and wet room floors. For commercial sealant work in Wimbledon, you deal with one contact from quote to sign-off, whether it’s one building or several.

Restaurants, cafés and hotel kitchens across London have joints at worktops, sinks and wall cladding that need to stay smooth and cleanable. We use sanitary and hygienic sealants, choosing food-safe products where food may touch the surface.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Keeping the joints sound

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

  • Mention any site permits or estates rules at quote stage
  • Squeegee showers and trays after busy periods
  • Make sure washroom ventilation is running
  • Report split joints at trays and basins early

Ask your cleaning team to use gentle products and soft cloths on sealant. Strong acids, solvents and scourers wear the surface and give mould a start.

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 failed joints are worth acting on quickly.

Toilets, showers and kitchens around Wimbledon

In London buildings, toilets and showers generally need to stay partly open, which is why the work is split into phases agreed in advance. The 2 miles around Wimbledon include five care or nursing homes. In a care setting, a mouldy or lifting joint in a wet room is a hygiene issue as much as a cosmetic one. Rooms are done a few at a time at times agreed with the home.

Healthcare estates like St George's Hospital (to the east of Wimbledon) expect contractors to follow their permits and cleaning rules in every washroom. Toilets at colleges like Wimbledon College of Arts, 0.7 miles to the south of Wimbledon, take heavy use from students and staff alike.

Wimbledon is about 7 miles south of City of Westminster, in Greater London. We send applicators to Wimbledon for washrooms and wet areas, handled exactly as we handle every other area. Across Greater London, 764 places are covered, including Wimbledon. We also cover London, around 7 miles from Wimbledon.

We also cover Crooked Billet (1 mile west), Wimbledon Park (1 mile north), Wimbledon Chase (1 mile south), Copse Hill (1 mile south-west) and Merton Park (1 mile south-east) for washrooms and wet areas.

On site: what to expect

Tell us your site hours and access windows and we’ll plan around them. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. Planning a London job such as one in Wimbledon starts with access: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Give us the hours we can be on site and we’ll schedule to suit.

  1. Every room is surveyed and the failed joints listed.
  2. You get a fixed quote with the phasing plan.
  3. The whole of the old bead is removed.
  4. Joints are degreased and dried.
  5. A sanitary silicone bead is laid and given a smooth tooled finish.
  6. Each area is handed back when ready.

Before we start on site

How the job changes by surface

Changing rooms and gyms

Changing rooms in gyms and leisure centres stay wet and warm, so mould is a constant battle. We use anti-mould sanitary silicone throughout.

IPS and cubicle panels

IPS panels and cubicle systems have joints at the wall, the floor and the worktop. They stop water reaching the panel boards.

Common questions from Wimbledon clients

Will you plan work around the academic year at somewhere like Kingston University Roehampton Vale Campus?

Yes, holiday working periods are the norm on campus jobs. Let us know which documents your site asks for, and we will confirm them alongside the quote.

Do you take on jobs in Wimbledon where loading and access are tightly controlled?

Yes. Inductions, permits and timed loading are routine for us in London. Share the building’s contractor rules and we’ll work to them.

How long do sealant joints last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

What sealant do you use in washrooms?

Sanitary silicone with anti-mould additives in most cases. We use neutral-cure versions on stone, some metals and near mirrors.

Do you take on small jobs?

We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.

How do you choose the sealant?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Do you phase washroom resealing?

We phase it so there are always facilities open. We work through the building a room or section at a time. Tell us your site hours and access windows and we will plan around them.

What sets the cost

What shapes the price:

  • Quantities, in metres or numbers
  • Phasing around occupants
  • Specialist products, such as fire-rated or hygienic sealants
  • Any access equipment needed

The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site rules also count.

Sending details for a quote

However big the job, these details speed things up:

  • Whether an asbestos survey exists
  • The product your specification calls for
  • The postcode of the building
  • Clear photos of the problem areas

Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to call the office on 01277 525 020 or use the quote form with what you know.

What we are called out for in Wimbledon

Mop buckets, trolleys and knocks from users damage joints near the floor at skirting lines, urinal bases and around pans.

Most enquiries start with one or more of the following:

  • Resealing that didn’t last because the old bead stayed
  • Failed sealant behind washroom basins
  • Complaints from staff, guests or users about tired washrooms
  • Sealant stained black around basins and showers

For a campus such as Kingston University Roehampton Vale Campus, 1.9 miles north-west of Wimbledon, showers in residences and washrooms in teaching blocks can be programmed around term dates.

What to look for in a quote

  • The named product and why it was chosen
  • What site paperwork they can supply
  • Whether old or failed sealant will be cut out, not overlaid
  • How long is the guarantee, and what does it include?

How to choose a sealant contractor

What we can’t put right

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • A dripping waste or valve behind a panel
  • Failed tanking beneath a wet-room floor or behind tiles
  • Mould caused by poor ventilation, which will return until the extract is fixed

If you’re not sure, just speak to us on 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer.
