How we handle washroom sealing in Roehampton

Black spotting along a sealant bead is not a cleaning problem. The growth is inside the sealant so it returns whatever the cleaning regime. Replacing the bead is the lasting treatment. We work on urinals and WCs, showers, trays and wet room floors and kitchens and tea points, and the usual reasons a site gets in touch are a new bead over an old one coming away and washrooms that look worn because of the sealant. Whoever orders the work in Roehampton, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.

In Roehampton, as across London, commercial kitchens and washrooms need sealed joints that can be cleaned properly. We use sanitary and hygienic sealants, choosing food-safe products where food may touch the surface.

Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

What sealant work can’t fix

A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be one of these:

  • A room that stays damp because ventilation isn’t working
  • A dripping waste or valve behind a panel
  • Leaks through tanking or membranes below the finishes

If you are not sure, just call the office on 01277 525 020 or use the quote form and we will give you a straight answer before you book.

Joints and surfaces we work on

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

What happens if it’s left?

Leaving the job until a shutdown often means living with it for months. With phasing, the work can go ahead while most facilities stay open. In Roehampton, each extra visit means more notices, permits and disruption, so a proper job first time, with the old sealant fully removed, is worth it.

Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Should maintenance staff do it?

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

On site: what to expect

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For a job in Roehampton, access comes first. Give us the hours we can be on site and we will schedule to suit.

  1. Every room is surveyed and the failed joints listed.
  2. You get a fixed quote with the phasing plan.
  3. Old sealant is removed completely and the faces cleaned.
  4. Each joint is cleaned and left dry.
  5. A sanitary silicone bead is laid and given a smooth tooled finish.
  6. Rooms reopen after the cure time.

Before we start on site

  • Tell staff and tenants when we will be in
  • Tell us which areas need to stay in use
  • Have the specification and drawings to hand

Related advice

Different surfaces, different methods

Kitchens and tea points

Worktop, sink and splashback joints in tea points take water and food. Sound joints keep those surfaces easy to clean.

Showers and trays

Shower trays move under foot and are wet all day. Tray perimeters are a frequent source of leaks.

What affects the price in Roehampton

There’s no standard rate for sealant work, since sites vary so much. What we take into account:

  • The site’s rules and procedures
  • Which sealant the job calls for
  • Distance, for remote addresses
  • How much there is to seal

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.

Details that help us quote

We can often quote from photos and a few details. Please tell us:

  • The site address and postcode
  • What the building is and how it’s used
  • Whether an asbestos survey exists
  • Any specification or named product

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we will fill any gaps with a visit.

Commercial washrooms in Roehampton

London offices and hotels normally can’t close all their washrooms at once, so we phase the work core by core or floor by floor with the building manager. Several hotels sit less than 2 miles from Roehampton. 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.

On a healthcare site such as Queen Mary's Hospital (under half a mile west of Roehampton), washroom work starts with the infection-control team’s sign-off. In a centre such as Kew Retail Park, 2.4 miles north-west of Roehampton, public washrooms are resealed a block of facilities at a time. For a campus such as University of Roehampton, which lies west of Roehampton, showers in residences and washrooms in teaching blocks can be programmed around term dates.

Your questions answered

Can you work in a London building with booked loading and goods-lift slots?

Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Send the building rules and access times with your enquiry. All of Greater London is inside the ULEZ, and our planning allows for it

Do hotels near Roehampton have to close for sealant work?

Rarely, if ever. We take a few rooms out at a time. Housekeeping and our team agree each day’s rooms.

Will cleaning remove black mould from sealant?

Cleaning may lighten it, but the mould returns. New anti-mould sanitary silicone is the treatment and point out if ventilation is part of the problem.

Will all the toilets be closed at once?

Just the room being resealed is out of use. Each room reopens after the sealant’s cure time and we start the next.

What if there’s asbestos in the old mastic?

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 work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.

Do you work in hospitals, clinics and care homes?

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

Will your applicators have CSCS cards?

Yes. Should the site need card details in advance, let us know and we will send them with the quote.
