About our washroom sealing in Thorns Beach

In healthcare and care settings, sealing is part of keeping surfaces cleanable. We work to your organisation’s estates and infection-control requirements and any site permits. Any records you need are confirmed with the quote. Most enquiries involve stained or open joints at kitchen sinks and worktops and gaps where vanity tops meet the wall, on IPS panels and cubicles, accessible toilets and changing rooms and urinals and WCs. A specialist sealant contractor works differently from a general builder: in Thorns Beach, that means joint design, primers and backing rod as standard.

Community buildings around smaller places like Thorns Beach have kitchens and toilets used by many people. Resealing sinks, worktops and WCs with anti-mould silicone keeps them clean and watertight.

We stand by our work with a 12-month guarantee. That covers our preparation and application, and if something we did falls short, we return to it.

When to call us in Thorns Beach

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

Things that typically lead to an enquiry:

  • Failed sealant in a tea point or staff kitchen
  • Discoloured joints around urinals and WC pans
  • Open joints at the base of cubicle panels
  • Sealant laid over old silicone and now peeling

Healthcare washrooms on sites such as Lymington New Forest Hospital, 4.6 miles west of Thorns Beach, are resealed area by area, under the site’s own infection-control rules.

Our contractor checklist

What happens if it’s left?

Bleaching black sealant may lighten it for a few days but the growth is inside the bead and returns. Replacement deals with the cause in the joint and your cleaning team stops chasing it. Around Thorns Beach, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.

Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Why clients in Thorns Beach choose us

  • Fully insured
  • Old sealant cut out, never sealed over
  • Constructionline member for supplier checks

Looking after the joints

To get the most from the new sealant:

  • Photograph and log failed joints across the estate
  • Share your site rules when you send details
  • Don’t leave an open joint at a basin or tray
  • Add sealant joints to planned maintenance checks

Where possible, have shower floors and trays squeegeed after busy periods. Standing water on a joint all day shortens its life.

A split joint at a shower tray can leak for a long time before anyone sees it. At that stage, boards or ceilings may need repair so failed joints are worth acting on quickly.

Site staff or a sealant specialist?

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

On site: what to expect

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself normally takes a morning or so for a small washroom, longer where showers and changing rooms are included, and we clear our waste as we work. For a building around Thorns Beach, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.

  1. Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
  2. We agree which rooms close and when, so users always have somewhere to go.
  3. We strip out the old bead and clean off the residue left behind.
  4. Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
  5. We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
  6. Each room is handed back once the sealant has had its cure time.

Getting the site ready

  • Make sure the joints can be reached
  • For older buildings, check the asbestos register before work
  • Send your site hours and access windows
