Common questions from Culverstone Green clients

Will the toilets in our Culverstone Green building be out of use?

Usually only some of them, for a short time. We work in phases so other facilities stay open. Sanitary silicone needs time to cure before the area is used, and we will tell you how long for the product used.

What site paperwork comes with a job in Culverstone Green?

We’ll confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. Our applicators are CSCS-carded, and we carry £5m public liability insurance.

How do we ask for a quote?

It works in four steps: send details, get a quote, we seal, guaranteed. The first step only needs photos and a postcode.

Are you CHAS accredited and on Constructionline?

Yes. We’re CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.

Do you phase washroom resealing?

We phase it 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.

What if there’s asbestos in the old mastic?

Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.

How long will the new sealant last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

Washroom sealing for commercial buildings in Culverstone Green

Accessible WCs, showers and changing areas have their own pinch points: wet-floor edges, tray perimeters, basin tops and the line where flooring meets the wall. An open joint there lets water track under flooring or behind wall panels, so we look at them closely. We work on kitchens and tea points, IPS panels and cubicles and vanity units and basins, and the usual reasons a site gets in touch are open joints along basins and vanity units and resealing that didn’t last because the old bead stayed. Facilities teams, main contractors and managing agents in Culverstone Green tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

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

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Building owners, agents and FMs in Culverstone Green

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

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 will confirm with the quote.

Aftercare for building managers

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

  • Respect the cure time before reopening each room
  • Report split joints at trays and basins early
  • Share your site rules when you send details
  • Include joints in routine washroom inspections

We hand each area back once the silicone has had the cure time the product needs. We’ll tell you when the wet areas can be used, and it helps if signs stay up until then.

Small numbers of failed joints are quick to phase in. Left, it tends to become a building-wide job with more phasing to plan.

Should maintenance staff do it?

Site maintenance staff can often handle a short internal joint. 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.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

On site: what to expect

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work typically takes a few hours for one toilet block, with bigger buildings phased across a number of visits, and we clear our waste as we work. For a building around Culverstone Green, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.

When something else is needed

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Panel boards already damaged by water
  • Water escaping beneath the floor rather than through a joint
  • A dripping waste or valve behind a panel

Not sure which it is? You can give us a call on 01277 525 020 or email drawings and photos and we’ll tell you honestly.

Joints and surfaces we work on

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

Leave it or put it right?

Water gets behind panels and under floors through a failed joint. That can lead to swollen boards, marked ceilings below and lingering smells, and fixing that takes far more work than resealing. Converted and older buildings near places like Culverstone Green tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site requirements come into it too.
