Washroom sealing in Yelsted

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Different surfaces, different methods

Changing rooms and gyms

Showers, floor edges and vanity units in changing rooms all need sound sealant, and we survey them together.

Showers and trays

If a tray moves too much or is cracked, it needs attention first and we flag that beforehand.

Washroom sealing in Yelsted

Since 2005 we have resealed commercial washrooms for facilities teams, contractors and building owners. We are CHAS accredited and a Constructionline member, with CSCS-carded applicators. We are fully insured. Our workmanship is guaranteed for 12 months. We work on showers, trays and wet room floors, accessible toilets and changing rooms and vanity units and basins, and the failures we are asked to look at most are split or peeling sealant at shower trays and open joints at the base of cubicle panels. One point of contact handles commercial sealant work in Yelsted from the first photographs to the final walk-round, for single jobs and planned programmes alike.

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

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Commercial clients in Yelsted

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, and our applicators hold CSCS cards.

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

Sanitary sealant for Yelsted buildings

Yelsted is about 33 miles from central London, within the office belt around the capital. Business park offices have washrooms in daily use by staff, so we phase work to keep some facilities open.

Schools such as St Augustine of Canterbury Catholic Primary School have toilets, changing rooms and kitchens that are best resealed in the holidays. At a retail site such as Parkwood Shopping Centre, 1.5 miles north-west of Yelsted, public and staff toilets see heavy use, so mouldy or split sealant is best replaced in phases.

Yelsted is about 3 miles south-east of Gillingham, in Kent. Looking for washroom sealing in Yelsted? We can help. Yelsted is one of 931 places we cover in Kent. Our London page has more on work in that area.

Our process

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work usually takes a morning or so for a small washroom, longer where showers and changing rooms are included, and our waste is bagged and taken away as we go. If others near Yelsted need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. Every room is surveyed and the failed joints listed.
  2. The fixed quote sets out the rooms, the products and the phasing.
  3. Old sealant is removed completely and the faces cleaned.
  4. Joints are degreased and dried.
  5. New anti-mould sealant goes in and is tooled neat.
  6. Rooms reopen after the cure time.

What we need from you

  • Share the asbestos register for older buildings
  • Tell us what induction or permit system the site runs
  • Tell staff and tenants when we will be in

Common problems we fix in Yelsted

Low-level joints get hit by mop buckets, cleaning trolleys and feet at skirting lines, urinal bases and around pans.

Most enquiries start with one or more of the following:

  • Stained sealant around pans and urinals
  • Complaints from staff, guests or users about tired washrooms
  • Shower tray joints that have opened up
  • Sealant laid over old silicone and now peeling

On a healthcare site such as KIMS hospital, 4 miles south-west of Yelsted, washroom work starts with the infection-control team’s sign-off.

Before you book anyone

  • How the existing material will be dealt with
  • How they handle RAMS and site documents
  • What level of public liability insurance do they hold?
  • Who will actually carry out the work

Questions to ask before you appoint anyone

What we can’t put right

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Leaks through tanking or membranes below the finishes
  • Swollen or delaminated boards behind panels or vanity tops
  • Water from plumbing, not from a joint

Not sure which it is? You can phone 01277 525 020 or send photos by email and we’ll tell you honestly before you book.

Where we work in Yelsted

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

Keeping the joints sound

After handover, a little attention goes a long way:

  • Clear standing water from shower floors where possible
  • Clean sealant with gentle products and a soft cloth
  • Respect the cure time before reopening each room
  • Keep a record of which washrooms need attention

Ask your cleaning team to use gentle products and soft cloths on sealant. Aggressive descalers, solvents and scouring pads shorten its life over time.

A few failed joints can be resealed with hardly any disruption. Left until every washroom is affected, it becomes a bigger programme with more phasing to plan.

Questions about Yelsted

Is hospital work, at somewhere like KIMS hospital, something you do?

Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Is Yelsted too far out for you?

No. Small places get the same service as large ones. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

Will cleaning remove black mould from sealant?

Not for long. The mould is inside the silicone, so it comes back however often it’s cleaned. Replacement is the lasting fix.

Do you guarantee washroom sealing?

Every job carries our 12-month guarantee. It applies to our workmanship, not to plumbing leaks or damp from poor ventilation.

What happens if old sealant might contain asbestos?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.

Will all the toilets be closed at once?

Only the area we’re working in is closed. Each room reopens after the sealant’s cure time and we start the next.

How long do sealant joints last?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
