Common questions from Teddington clients

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

Yes, we plan every London job around the building’s own access rules. The building manager’s rules go straight into our method.

Could you schedule work at a campus like St Mary's University for the vacation?

Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

How long does a job like this take?

It depends on the scope, but the work usually takes a few hours for one toilet block, with bigger buildings phased across a number of visits. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.

Is it possible to just clean mouldy silicone?

Surface cleaning won’t reach mould that has rooted into the bead. We replace the sealant with an anti-mould sanitary grade and point out if ventilation is part of the problem.

Can you send site paperwork?

Each site asks for different documents, so tell us what you need and we’ll confirm it when we quote.

Can the sealant be colour-matched?

In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We’ll confirm the colours available for the specified product.

Can you work to our specification?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.

How we handle washroom sealing in Teddington

In healthcare and care settings, sealing is part of keeping surfaces cleanable. We work to your organisation’s estates and infection-control requirements and any site permits. Tell us what records you need and we will confirm with the quote. Site teams most often ask us about failed joints along IPS and cubicle panels and shower tray joints that have opened up, on accessible toilets and changing rooms, IPS panels and cubicles and vanity units and basins. Whoever orders the work in Teddington, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.

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.

Work we carry out in Greater London comes with a 12-month guarantee. If an installation problem shows up, ring 01277 525 020 or use the quote form and we’ll arrange a return visit.

What sets the cost

To price the job, we consider:

  • How accessible the joints are
  • Induction, permit and paperwork requirements
  • Which sealant the job calls for
  • The size and state of each joint

Pricing washrooms and wet areas depends on how many there are, their condition and the access. Ask us for a fixed quote.

What to include in your enquiry

Whether it’s one area or a whole building, the same details help:

  • Rough lengths or quantities, or drawings if you have them
  • Whether the building will be occupied during the work
  • A wide shot and a close-up of the area
  • Asbestos survey details if the building is older

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 the details over.

Different surfaces, different methods

Changing rooms and gyms

Changing rooms can be phased so one stays open. Phasing follows your site hours and access windows.

Basins and vanity tops

Basin joints get wet every time someone washes their hands, so the joint to the wall and around each bowl fails early. We remove the old bead and lay a fresh one of sanitary silicone.

Keeping the joints sound

For the best life from the joints:

  • Share your site rules when you send details
  • Keep a record of which washrooms need attention
  • Add sealant joints to planned maintenance checks
  • Don’t leave an open joint at a basin or tray

Include sealant joints in your planned maintenance checks. Check for mould spots, splits, lifting edges and open joints at trays, basins and urinals and log what you find.

Leaks through tray and wet-floor joints can go unseen until a ceiling marks below. By then, other trades may be needed as well so failed joints are worth acting on quickly.

Sanitary sealant for Teddington buildings

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. The area within 2 miles of Teddington holds plenty of hotels. En suite bathrooms, staff changing rooms and kitchens all need their sanitary silicone renewed in time. The work can go floor by floor, agreed with housekeeping.

Office toilets at parks like Newmans Shipyard & Business Park (to the north of Teddington) take steady weekday use, and mouldy silicone soon shows. Halls of residence and teaching buildings at universities such as St Mary's University, 0.7 miles north of Teddington, are easiest to reseal during vacations.

Teddington is about 5 miles west of Wimbledon, in Greater London. Commercial clients in Teddington can call on us for washrooms and wet areas. We work across 764 places in Greater London, from busy centres to rural villages. London is covered too, around 11 miles from Teddington.

Work on washrooms and wet areas is covered throughout TW11, TW12, TW2 and TW1, whatever the building. Streets here include Station Road, High Street and Church Road, and sites on any of them can send details for a fixed quote. With the A311 and A313 nearby, Teddington is easy to get to with materials and equipment. Nearby places we also cover include Strawberry Hill (1 mile north), Fulwell (1 mile north-west), Hampton Hill (1 mile west), Ham (1 mile north-east) and Eel Pie Island (1 mile north) for washrooms and wet areas. Nearby towns on our patch include London (11 miles north-east), City of Westminster (10 miles north-east), Marylebone (10 miles north-east), Kensington (8 miles north-east), St Pancras (12 miles north-east) and Shoreditch (13 miles north-east).

Near you in Teddington

We work on buildings around Bushy Park, Turing House School and Newland House School, among other places. There’s a railway station in Teddington itself: Teddington station. A little further out are Teddington Memorial Hospital (less than half a mile west) and Eel Pie Island Museum (1.5 miles north). The countryside around Teddington includes Ham Lands and Kew Gardens Lake.

What we can’t put right

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

  • Leaking pipes, traps, wastes or cisterns, which need a plumber
  • Leaks through tanking or membranes below the finishes
  • Fittings that move too much to hold a bead

If in doubt, call the office on 01277 525 020 or email drawings and photos and we’ll say what we think.

Joints and surfaces we work on

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

Do you need washroom sealing in Teddington?

Washrooms are warm, damp and full of organic residue, and silicone joints hold onto all three. Even anti-mould grades can be colonised over time where extraction is poor.

Things that usually lead to an enquiry:

  • Failed joints along IPS and cubicle panels
  • Stained or open joints at kitchen sinks and worktops
  • Shower tray joints that have opened up
  • Mould spotting along silicone joints

For centre management at a site such as Bentall Centre, 1.6 miles to the south-east of Teddington, washroom work is planned around footfall.

Before you book anyone

  • Their pre-qualification and accreditations
  • Who will actually carry out the work
  • The named product and why it was chosen
  • Will failed sealant be removed rather than covered?

How to choose a sealant contractor

From enquiry to sign-off

Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open 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. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.

  1. We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
  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. 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. You get a reopening time for every room, with signage left up until then.

Preparing the site

  • Warn occupants and staff about the work
  • Send your site hours and access windows
  • Flag any permit to work we’ll need
