FAQs: Long Ditton

Can you work around term dates at a campus such as Kingston University Penrhyn Road Campus?

Yes. Education sites usually want the work in vacations or in phases during term, and we plan to suit. Let us know which documents your site asks for, and we will confirm them alongside the quote.

Can you work in a care home near Long Ditton with residents in?

Yes. We work around residents’ routines, a room or two at a time. We follow the home’s own procedures throughout.

Do you need to remove the old sealant?

The whole of the old bead is removed and the surfaces cleaned before resealing. That’s what makes the new joint last.

How do you deal with asbestos in old sealant?

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.

How soon can the area be used again?

That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.

Are your applicators CSCS-carded?

Yes. Should the site need card details in advance, let us know and we’ll send them with the quote.

What do you charge?

There isn’t a price list, because every site is different. With photos or drawings, we can give you a fixed quote.

Washroom sealing in Long Ditton, done properly

When mould has spotted a silicone joint, more cleaning won’t remove it. The mould has rooted into the silicone itself, which is why it comes back however often it is treated. Only replacement gets rid of it for good. We work on vanity units and basins, IPS panels and cubicles and showers, trays and wet room floors, and what we are called in for most is failed joints along IPS and cubicle panels and failed sealant behind washroom basins. Most enquiries from Long Ditton 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.

Pub and restaurant kitchens around smaller places like Long Ditton work hard on their joints. Sealed joints at sinks, worktops and splashbacks help keep the kitchen cleanable.

We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Honest limits

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Swollen or delaminated boards behind panels or vanity tops
  • Condensation from failed extract fans
  • Leaking pipes, traps, wastes or cisterns, which need a plumber

If you are not sure, just speak to us on 01277 525 020 or email us and we will give you a straight answer before you book.

Surfaces we seal

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

Signs you need washroom sealing in Long Ditton

Commercial cleaning is harder on sealant than everyday use. Strong chemicals, scourers and jet washing roughen, discolour or lift a bead so grime sticks to the damaged surface.

If one of these sounds familiar, it’s time for a closer look:

  • Stained or open joints at kitchen sinks and worktops
  • A new bead over an old one coming away
  • Users noticing mouldy joints
  • Panel joints letting water behind

For a college such as Hillcroft College, which lies north-east of Long Ditton, half-term and summer give the windows for washroom work.

Choosing a commercial sealant contractor

On site: what to expect

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. For a job in Long Ditton, the main thing is a clear picture of the work. You will then get a fixed price for the work.

  1. First, the phasing is agreed so facilities stay open.
  2. Leaks, loose panels or damp are pointed out first.
  3. Old sealant is stripped and the faces prepared.
  4. We reseal with the grade suited to each area.
  5. We confirm reopening times for each washroom.

Before we start on site

  • Arrange parking or a loading space
  • Have the specification and drawings to hand
  • Share the asbestos register for older buildings

Why deal with it now?

When a washroom looks worn, a refit isn’t the only answer. Where tiles, panels and fittings are sound, new sealant may be enough to put it right for now. Sealant hardens, cracks and loses grip with age, UV and movement. Replacing it before it fails keeps water out.

The specified product makes a difference, and so does the preparation. Access, phasing and site requirements come into it too.

What you get with us

  • Clear, fixed quotes
  • A Constructionline member, so easy to vet
  • Joints cleaned back to sound surfaces
  • Our applicators hold CSCS cards

How the job changes by surface

Showers and trays

If a tray moves too much or is cracked, it needs attention first, and we’ll say so before resealing.

Healthcare and care settings

Healthcare work is phased so wards, clinics or residents’ areas keep their facilities. Records you need can be confirmed with the quote.
