Washroom sealing in Cooling Street

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

Our process

We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. Smaller jobs around Cooling Street can be grouped with others nearby, which keeps travel down. You’ll have a fixed quote before work starts.

  1. We survey each room, count the joints and note anything behind them that needs another trade.
  2. A phasing plan keeps part of the building’s facilities in use at all times.
  3. The failed silicone is stripped and every face scraped clean of residue.
  4. We clean and dry every surface so the new sealant can grip.
  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.

Before we start on site

  • Let us know about inductions and permits
  • Send your site hours and access windows
  • Send any specification or drawings in advance

Advice

Washroom sealing in Cooling Street

Closing all the facilities in a building isn’t an option. We phase the work one washroom, one bank of cubicles or one changing room at a time, so staff, guests or pupils always have somewhere to go. Give us your site hours and access windows and the phasing is planned around them. Site teams most often ask us about a new bead over an old one coming away and discoloured joints around urinals and WC pans, across kitchens and tea points, IPS panels and cubicles and urinals and WCs. Searching for sealant specialists in Cooling Street? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

In and around smaller places like Cooling Street, washroom work is often in halls, pubs, primary schools, care homes and holiday accommodation. Sealant that has gone black with mould normally can’t be cleaned, so it is cut out and replaced.

A 12-month guarantee applies to all our work. If an installation problem shows up, phone 01277 525 020 or email drawings and photos and we will arrange a return visit.

Cooling Street: questions and answers

Is Cooling Street too small for you to travel to?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.

Is hospital work, at somewhere like French Hospital, something you do?

Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Do you do washroom sealing in healthcare settings?

We work in clinics, hospitals and care homes. Tell us what records you need and we’ll confirm with the quote.

Is old silicone taken out first?

We always remove it. New silicone won’t stick to the old so a bead over the top fails quickly.

Do you work to architects’ specifications?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.

Do you offer coloured sealant?

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 will confirm the colours available for the specified product.

What happens if old sealant might contain asbestos?

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. Removing asbestos is a job for asbestos specialists, not us.

Keeping Cooling Street washrooms open while we work

The sea is no more than about 3 miles from Cooling Street, and coastal places often have hotels, guest houses and holiday accommodation with busy seasons. Heavy seasonal use is hard on shower and basin sealant, so we plan the work for quieter weeks where possible. Cooling Street lies roughly 26 miles out from central London, in a commuter belt where offices and business parks are common. Business park offices have washrooms in daily use by staff, so we work a block of facilities at a time.

For a hall at a building such as St James' Church, resealing the kitchen and toilets can be fitted between bookings. Units at estates like Nuralite Industrial Estate, 2.7 miles to the west of Cooling Street, have welfare blocks whose showers and toilets see shift after shift. For a campus such as University of Greenwich - Medway (3.3 miles south of Cooling Street), showers in residences and washrooms in teaching blocks can be programmed around term dates.

Site staff or a sealant specialist?

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.

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.

What we can’t put right

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

  • Condensation from failed extract fans
  • Panel boards already damaged by water
  • Leaking pipes, traps, wastes or cisterns, which need a plumber

Not sure which it is? You can give us a call on 01277 525 020 or use the quote form and we’ll tell you honestly before you book.

Joints and surfaces we work on

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

Keeping the joints sound

For the best life from the joints:

  • Squeegee showers and trays after busy periods
  • Keep a record of which washrooms need attention
  • Respect the cure time before reopening each room
  • Report faulty extraction promptly

Ask your cleaning team to use gentle products and soft cloths on sealant. Aggressive descalers, solvents and scouring pads shorten its life and give mould a start.

Leaks through tray and wet-floor joints can go unseen until a ceiling marks below. At that stage, boards or ceilings may need repair, so reseal when you first spot a split.

What sets the cost

These are the things that shape the price:

  • Joint width, depth and condition
  • Induction, permit and paperwork requirements
  • Any access equipment needed
  • Quantities, in metres or numbers

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Before you send an enquiry

It doesn’t need to be a full survey. These details are enough to start:

  • The postcode of the building
  • Clear photographs of the problem areas
  • When you need the work done
  • Rough lengths or quantities, or drawings if you have them

Send us photos, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.

How the job changes by surface

Urinals and WC pans

The joint between a pan and the floor is easy to overlook. They are checked with everything else.

Kitchens and tea points

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