Washroom sealing across Weald

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Leave it or put it right?

Sealing on top of old silicone saves nothing. Silicone won’t grip silicone, so it lifts and holds moisture underneath. Cutting out completely and cleaning back takes a little longer and lasts. Converted and older buildings near places like Weald tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

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.

Why us?

  • Standard and matched colours in many product ranges
  • Commercial sealant work since 2005
  • Colour options checked against the specified product
  • One phone line for London, the South East and Scotland

Washroom sealing for commercial buildings in Weald

Whether it’s a single toilet block in Weald or a programme across several buildings, we work the same way: details first, then a fixed quote, then the work, then the 12-month guarantee. Photos and a rough count of basins, urinals, showers and cubicles help us give a quick quote, or we can arrange a visit. We work on IPS panels and cubicles, showers, trays and wet room floors and vanity units and basins, and the failures we are asked to look at most are sealant stained black around basins and showers and stained sealant around pans and urinals. A single leaking joint is often how a building in Weald first comes to us: 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 Weald have busy toilets and kitchens. We plan the work around bookings and opening times.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

When to bring in a specialist

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Quoting for work in Weald

Before we quote, we look at:

  • How much existing material needs removing
  • Access and working height
  • Location, for remote and island sites
  • Quantities, in metres or numbers

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

What to include in your enquiry

We can often quote from photos and a few details. It helps to include:

  • The asbestos register, for older buildings
  • Any dates the work must fit around
  • What the building is and how it’s used
  • Access details, including height

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.

Our process

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself usually takes between a morning and a week or so, set by the number of rooms and the phasing you need, and we clear our waste as we work. If others near Weald need work, visits can be combined. A fixed quote is given before anything starts.

  1. We agree which washrooms close and when.
  2. Anything behind the joints that needs another trade is flagged.
  3. Failed sealant and residue are stripped out.
  4. We reseal with the grade suited to each area.
  5. We confirm reopening times for each washroom.

Before we start on site

  • Explain the parking and delivery arrangements
  • Send asbestos survey details if the building is pre-2000
  • Move anything stored against the joints

FAQs: Weald

Can you work around term dates at a campus such as University of Oxford?

Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Do you take on work at healthcare sites like Longworth Hospital?

Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.

Which sealant will you use?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Do you offer coloured sealant?

Often, 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.

Is there a guarantee on the work?

There is a 12-month guarantee on our workmanship, and we carry public liability insurance.

Will all the toilets be closed at once?

We phase it so there are always facilities open. One washroom, one bank of cubicles or one changing room is done at a time around your site hours and access windows.

What do you charge?

We don’t publish prices, because every site is different. Send photographs or drawings and we will price it at a fixed figure.

Building owners, agents and FMs in Weald

Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules.

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

Looking after the joints

Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Report split joints at trays and basins early
  • Keep extract fans working and vents clear
  • Avoid scourers and harsh descalers on silicone
  • Clear standing water from shower floors where possible

Each room goes back into use only when the sealant has cured enough. You will be told when showers and basins can be used again and signage stays in place until that time.

Mould in a joint spreads along the bead and into nearby grout and users notice. Replacing it early keeps the job to a reseal.
