Washroom sealing in Marden Thorn, done properly

We reseal washrooms and wet areas in offices, hotels, schools, universities, gyms, healthcare buildings and care homes, along with staff kitchens and tea points. The products and the method are chosen for how heavily each space is used. Most enquiries involve open joints along basins and vanity units and stained or open joints at kitchen sinks and worktops, across vanity units and basins, urinals and WCs and IPS panels and cubicles. One point of contact handles commercial sealant work in Marden Thorn from the first photos to the final walk-round, for single jobs and planned programmes alike.

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

The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

After the work

For the best life from the joints:

  • Include joints in routine washroom inspections
  • Clear standing water from shower floors where possible
  • Avoid scourers and harsh descalers on silicone
  • Keep extract fans working and vents clear

Mild cleaning products and non-abrasive cloths look after sanitary silicone best. Aggressive descalers, solvents and scouring pads shorten its life and give mould a start.

Small numbers of failed joints are quick to phase in. Left until every washroom is affected, it becomes a bigger programme with more phasing to plan.

What happens if it’s left?

Gaps and mould in joints give dirt and bacteria somewhere to sit which matters most in healthcare, food and education settings. Sound, smooth joints are much easier to keep clean. Converted and older buildings near places like Marden Thorn tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Why appoint us

  • Colours chosen to suit frames, cladding or finishes where possible
  • Public liability insurance in place
  • Work carried out by CSCS-carded applicators
  • One number for every site we cover

From enquiry to sign-off

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 usually 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 work around Marden Thorn, we aim to finish in one visit, so photos and measurements up front really help. Then the right materials arrive with us.

  1. We survey each room, count the joints and note anything behind them that needs another trade.
  2. The phasing is agreed so there are always facilities open.
  3. Failed silicone is removed completely and the surfaces cleaned of every trace.
  4. Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
  5. New sanitary silicone with anti-mould additives goes in and is tooled neat.
  6. Each room is handed back once the sealant has had its cure time.

Common questions from Marden Thorn clients

Will the toilets in our Marden Thorn building be out of use?

Not all at once. We take one block of facilities at a time. Sanitary silicone needs time to cure before the area is used, and we will tell you how long for the product used.

What documents will you need to give us for a job in Marden Thorn?

RAMS, insurance certificate, CSCS details: list what the site needs and we will confirm it with the quote. Our applicators are CSCS-carded, and we carry £5m public liability insurance.

Can you handle several sites?

Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.

What will the job cost?

Every job gets its own fixed quote. For yours, ring 01277 525 020 or email us with a description of the work.

Do you work in hospitals, clinics and care homes?

We work in clinics, hospitals and care homes. Tell us what records you need and we’ll confirm with the quote before we start.

Do you have public liability insurance?

Yes. We are fully insured, including public liability cover.

Will cleaning remove black mould from sealant?

Surface cleaning won’t reach mould that has rooted into the bead. New anti-mould sanitary silicone is the treatment and check the ventilation isn’t the cause.

Different surfaces, different methods

Urinals and WC pans

Joints around urinals and WC pans take splashes, cleaning chemicals and knocks. Once they discolour or split, they hold odours and make the room look neglected.

Healthcare and care settings

Accessible and assisted washrooms are used and cleaned intensively, so their joints often need renewing sooner.

What we can’t put right

We check first that sealant really is the fix. It won’t put right:

  • Leaking pipes, traps, wastes or cisterns, which need a plumber
  • Condensation from failed extract fans
  • Panel boards already damaged by water

If you are not sure, just call the office on 01277 525 020 or use the quote form and we’ll give you a straight answer before you book.

What we seal

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

What affects the price in Marden Thorn

We price every job individually. The main factors are:

  • Location, for remote and island sites
  • Backing rod, priming and other preparation
  • The total length or number of joints
  • Whether the work must be split into stages

We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

Before you send an enquiry

However big the job, the same details help:

  • The postcode of the building
  • Clear photographs of the problem areas
  • Any dates the work must fit around
  • Any specification or named product

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, ring 01277 525 020 or use the quote form.
