A few photographs and a count of fittings are enough for a quick quote, or we can arrange a visit. If you have sealant stained black around basins and showers and complaints from staff, guests or users about tired washrooms, we can put it right, on vanity units and basins, showers, trays and wet room floors and kitchens and tea points alike.

In and around smaller places like Cross-at-Hand, 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.

Different surfaces, different methods

Basins and vanity tops

Natural stone tops can be marked by acetoxy silicone and we choose a neutral-cure grade for them.

Urinals and WC pans

Urinal backs, troughs and slab joints are resealed with sanitary silicone once the whole of the old bead has gone.

How the quote is worked out

A fixed quote reflects the actual work. It takes account of:

  • Access and working height
  • The product specified
  • Removal of failed or old sealant
  • Quantities, in metres or numbers

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

What we need to price the job

There’s no need for a formal survey. These details are enough to start:

  • The site address and postcode
  • A wide shot and a close-up of the area
  • Any specification or named product
  • Drawings or a marked-up plan, if available

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photographs and a few notes.

Questions about Cross-at-Hand

Is Cross-at-Hand off your patch?

Not at all. Cross-at-Hand is within our area. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Will all the washrooms in our Cross-at-Hand building be closed at once?

Rarely all at once: work is phased so some facilities are always available. Each area is handed back once the sealant has cured enough to use.

How many days will you need on site?

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 will give you a timescale with the quote.

Which sealant will you use?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Are you CHAS accredited?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

Do you use special sealant for toilets and showers?

It depends on the joint. Washrooms and showers take anti-mould sanitary silicone while kitchens may need a food-safe grade.

Do you phase washroom resealing?

The work is phased so there are always facilities open. We work through the building a room or section at a time. Tell us your site hours and access windows and we will plan around them.

General trades versus a specialist

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

General builders and handymen seal joints, but it isn’t their main trade. 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.

What we are called out for in Cross-at-Hand

Mop buckets, trolleys and knocks from users damage joints near the floor at skirting lines, urinal bases and around pans.

Typical triggers for a call:

  • Sealant stained black around basins and showers
  • Sealant laid over old silicone and now peeling
  • Complaints from staff, guests or users about tired washrooms
  • Sealant lifting along a tray edge

Welfare facilities in units on estates such as Barradale Farm Industrial Estate (2.8 miles east of Cross-at-Hand) have showers, toilets and kitchens with sealant that works hard.

Send that with the details and we’ll confirm the plan with the quote.

  1. We agree which washrooms close and when.
  2. Leaks, loose panels or damp are pointed out first.

  • Point out parking and an unloading spot
  • Send any specification or drawings in advance

Why act early in Cross-at-Hand

A failed joint behind a basin or along a shower tray lets water run where it shouldn’t. In a commercial building that can mean damaged boards, stained ceilings on the floor below and odours which costs more to fix than a reseal. Converted and older buildings near places like Cross-at-Hand tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we will explain how it’s made up.
