Washroom sealing for Westwood sites

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

How we handle washroom sealing in Westwood

Our washroom work covers offices, hotels, schools and colleges, leisure centres and gyms, clinics and care homes, along with staff kitchens and tea points. The products and the method are chosen for how heavily each space is used. Most enquiries involve urinal joints that look unhygienic and stained or open joints at kitchen sinks and worktops, on IPS panels and cubicles, accessible toilets and changing rooms and vanity units and basins. Most enquiries from Westwood start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Farm shops, cafés and venues in converted rural buildings around places like Westwood have busy toilets and kitchens. Tell us your opening times and quiet periods and we’ll plan around them.

We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Westwood: questions and answers

Can you take on a job at a hospital such as Darent Valley Hospital?

Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.

Is a smaller place like Westwood outside your area?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Can washrooms stay open while you work?

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

Will your applicators have CSCS cards?

Yes. Our applicators hold CSCS cards, which many sites require.

Do you need to see the site first?

Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit before quoting.

Can you follow the specification on our project?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.

Will you quote for a small job?

Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.

After the work

Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:

  • Keep a record of which washrooms need attention
  • Report split joints at trays and basins early
  • Clear standing water from shower floors where possible
  • Share your site rules when you send details

Keep extract fans working and vents clear. A room that stays damp will grow mould on almost anything so report fans that aren’t working to your building services team.

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.

How the job changes by surface

Kitchens and tea points

Worktop, sink and splashback joints in tea points take water and food. Sealed joints leave no gaps for food and dirt.

Basins and vanity tops

Water getting past a vanity top joint can swell the board beneath. Prompt resealing keeps the unit sound.

From enquiry to sign-off

In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then handed back before the next one starts. Rural sites near Westwood may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

  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. Failed silicone is removed completely and the surfaces cleaned of every trace.
  4. Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
  5. A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
  6. Each room is handed back once the sealant has had its cure time.

What we need from you

  • Move anything stored against the joints
  • Have the specification and drawings to hand
  • Explain the parking and delivery arrangements

Advice

General trades versus a specialist

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Owners, agents and contractors

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Westwood can form part of a wider programme.

Toilets, showers and kitchens around Westwood

Central London is about 18 miles from Westwood. Office toilets in the commuter belt are in use from first arrivals to last departures, so we phase work to keep some facilities open.

Halls of residence and teaching buildings at universities such as University of Greenwich (2.4 miles north-west of Westwood) are easiest to reseal during vacations. At a school such as Bean Primary School, changing rooms and kitchens need cleanable joints as much as the toilets. Halls linked to places like Church of Saint Mary Magdalene host groups all week, which is hard on kitchen and toilet sealant.

When something else is needed

Before quoting, we check that sealant is the right answer. It won’t put right:

  • Water escaping beneath the floor rather than through a joint
  • Loose panels, vanity units or tiles, which need fixing first
  • Swollen or delaminated boards behind panels or vanity tops

If you’re not sure, just call the office on 01277 525 020 or email the details over and we will give you a straight answer.

Surfaces we seal

  • Showers, trays and wet room floors
  • Kitchens and tea points
