Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Aftercare for building managers

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Share your site rules when you send details
  • Keep washrooms out of use until we say the sealant has cured
  • Keep a record of which washrooms need attention
  • Include joints in routine washroom inspections

Mild cleaning products and non-abrasive cloths look after sanitary silicone best. Aggressive descalers, solvents and scouring pads shorten its life over time.

Water getting behind IPS panels and vanity units can swell the boards. Once that happens, a reseal won’t fix them.

Washroom sealing in Tooting

Accessible WCs, showers and changing areas have their own pinch points: wet-floor edges, tray perimeters, basin tops and the line where flooring meets the wall. An open joint there lets water track under flooring or behind wall panels, so we look at them closely. We work on urinals and WCs, kitchens and tea points and vanity units and basins, and what we’re called in for most is failed joints along IPS and cubicle panels and open joints along basins and vanity units. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Tooting it comes down to the same thing: the right product in a properly prepared joint.

Building managers in Tooting usually need some facilities open throughout. Washrooms are done core by core or floor by floor, with signage and a plan agreed beforehand, so staff and visitors can always find an open washroom.

A 12-month guarantee applies to all our work. Should something we installed fail, ring 01277 525 020 or use the quote form and we will come back to it.

Surface by surface

Showers and trays

In staff, hotel and changing-room showers, the tray joint and wall corners take the hardest use. Each bead is stripped, the joint dried and new sealant laid.

Kitchens and tea points

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

Commercial washrooms in Tooting

There are plenty of hotels within about 2 miles of Tooting. En suite bathrooms, staff changing rooms and kitchens all need their sanitary silicone renewed in time. The 2 miles around Tooting include five care or nursing homes. Care home wet rooms and en suites are used every day and cleaned hard, which tells on the silicone. Work is agreed with the manager, around residents’ routines.

For a campus such as University of the Arts London (3.3 miles north of Tooting), showers in residences and washrooms in teaching blocks can be programmed around term dates. Toilets at places like Priory Retail Park, 1 mile south-west of Tooting, are cleaned constantly, which is hard on silicone. Hotels such as Antoinette Hotel (to the south-west of Tooting) have en suite bathrooms where tired silicone at the bath, tray and basin is replaced room by room.

Tooting is about 3 miles south-west of Stockwell, in Greater London. Looking for washroom sealing in Tooting? We can help, as we do across Greater London. Across Greater London, 764 places are covered, including Tooting. We also cover London, around 6 miles from Tooting.

Building owners, agents and FMs in Tooting

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Tooting can form part of a wider programme.

Whether you are a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

Diagnose, treat, sign off

Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.

  1. We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
  2. A phasing plan keeps part of the building’s facilities in use at all times.
  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. We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
  6. Each room is handed back once the sealant has had its cure time.

Getting the site ready

  • Flag any permit to work we’ll need
  • Send your site hours and access windows

Why it’s worth doing now in Tooting

A failed joint behind a basin or along a shower tray lets water run where it shouldn’t. That can lead to swollen boards, marked ceilings below and lingering smells which costs more to fix than a reseal. Failed sealant in a building in Tooting can quickly affect neighbours, tenants or the floor below: water travels through shared structures, and a small leak becomes a dispute between occupiers. Dealing with it early is simpler for everyone.

The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

Quoting for work in Tooting

Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:

  • How accessible the joints are
  • Distance, for remote addresses
  • Induction, permit and paperwork requirements
  • Removal of failed or old sealant

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we’ll explain how it’s made up.

Sending details for a quote

A good diagnosis starts with the right details. Let us know:

  • Clear photographs of the problem areas
  • Anything awkward about access or site hours
  • Approximate linear metres or a joint schedule
  • Asbestos survey details if the building is older
