About our washroom sealing in The Warren

In a busy washroom, the sealant normally gives up long before the tiles or fittings. Around basins, urinals, cubicles, IPS panels and shower trays it takes water, soap, cleaning chemicals and knocks every day, and once mould grows into it, it can’t be scrubbed out. The fix is to remove it completely and reseal with sanitary silicone containing anti-mould additives. Site teams most often ask us about sealant laid over old silicone and now peeling and failed sealant behind washroom basins, across kitchens and tea points, vanity units and basins and urinals and WCs. One point of contact handles commercial sealant work in The Warren from the first photographs to the final walk-round, whether it’s one building or several.

Pub and restaurant kitchens around smaller places like The Warren work hard on their joints. Smooth, sealed joints at worktops, sinks and wall cladding make cleaning easier.

We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

FAQs: The Warren

Is a smaller place like The Warren outside your area?

Not at all. The Warren is within our area. London and every South East county are within our area. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Could you schedule work at a campus like Imperial College Silwood Park Campus for the vacation?

Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

When can showers be used after new sealant?

Each sealant has a cure time before it should get wet. We plan the phasing around that so there are always rooms open.

Can weather delay the job?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.

What happens if old sealant might contain asbestos?

The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.

Which sealant will you use?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Can you handle several sites?

Yes. A group of buildings can go on one quote, and you deal with one contact throughout across South East England, Greater London and Scotland.

After the work

Keep the joints in good shape with a few simple steps:

  • Don’t leave an open joint at a basin or tray
  • Include joints in routine washroom inspections
  • Mention any site permits or estates rules at quote stage
  • Clear standing water from shower floors where possible

If a joint we sealed fails within 12 months, tell us and we’ll look at it. After that, a routine look catches failing joints early.

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 failed joints are worth acting on quickly.

Commercial clients in The Warren

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in The Warren can sit alongside others in a wider programme.

Surface by surface

Kitchens and tea points

Staff kitchens and tea points have joints at worktops, sinks and splashbacks. Sealed joints leave no gaps for food and dirt.

Urinals and WC pans

The joint between a pan and the floor is easy to overlook. We include them in the survey.

What happens if it’s left?

Water gets behind panels and under floors through a failed joint. That can lead to swollen boards, marked ceilings below and lingering smells which costs more to fix than a reseal. Over time, UV, weather and movement wear any sealant out. Renewing it in good time keeps the building weathertight.

The price depends on how many linear metres there are, how much old material needs removing and the access. Call for a fixed quote when you are ready.

Why us?

  • One contact handling all your sites
  • Sealing commercial buildings since 2005

When to call us in The Warren

Commercial cleaning is harder on sealant than everyday use. Harsh products, abrasive pads and pressure washing break down a joint’s surface and edges so grime sticks to the damaged surface.

These are often picked up first by site or facilities staff:

  • Complaints from staff, guests or users about tired washrooms
  • Sealant stained black around basins and showers
  • Open joints at the base of cubicle panels
  • Urinal joints that look unhygienic

Office toilets at parks like Bracknell Enterprise Centre, 1.8 miles to the north-west of The Warren, take steady weekday use, and mouldy silicone soon shows.

What your quote should include

  • Will CSCS-carded applicators be on site?
  • Is the sealant right for the movement and the substrate?
  • Health and safety accreditation such as CHAS
  • How the joint faces will be prepared and primed
