Washroom sealing in Hampers Green, done properly

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 they get particular attention. If you are dealing with sealant laid over old silicone and now peeling and shower tray joints that have opened up, we can help, on vanity units and basins, urinals and WCs and IPS panels and cubicles alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Hampers Green, preparation and product choice get the time they need.

Community buildings around smaller places like Hampers Green have kitchens and toilets used by many people. Fresh anti-mould sanitary silicone at sinks, worktops and toilets keeps them cleanable.

Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

Common questions from Hampers Green clients

Would you work within a site like Midhurst Community Hospital?

Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.

Is a smaller place like Hampers Green outside your area?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.

How soon can a washroom be used after resealing?

The silicone needs time to cure before water reaches it. Phasing is planned with the cure time in mind so there are always rooms open.

Do you work to architects’ specifications?

Yes. We follow the specification, along with the manufacturer’s installation guidance.

Is it OK to put new silicone on top of the old?

The failed bead is always removed. Fresh silicone can’t key to an old bead, so sealing over it soon peels.

What if there’s asbestos in the old mastic?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.

Do you use special sealant for toilets and showers?

An anti-mould sanitary silicone in the majority of cases. Neutral-cure grades are used where acetoxy types could mark metals, stone or mirror backings.

Signs you need washroom sealing in Hampers Green

Cubicle panels, IPS panels and vanity units flex when people lean on them or doors are slammed and trays shift slightly with each user. If the joint wasn’t laid to take that movement, it tears or peels away.

Clients typically get in touch after noticing one or more of the following:

  • Discoloured joints around urinals and WC pans
  • Failed sealant in a tea point or staff kitchen
  • Open joints at the base of cubicle panels
  • Sealant stained black around basins and showers

At a school such as Petworth Cof E Primary School, changing rooms and kitchens need cleanable joints as much as the toilets.

Questions to ask before you book

  • Their plan for phasing and protecting the area
  • Whether primer will be used where the manufacturer specifies it
  • Whether old or failed sealant will be cut out, not overlaid
  • The terms of the workmanship guarantee

Keeping Hampers Green washrooms open while we work

For an occupier at a site such as Hampers Common Industrial Estate, which lies south of Hampers Green, the canteen and welfare facilities need cleanable joints as much as any office.

Why deal with it now?

Bleaching black sealant may lighten it for a few days but the growth is inside the bead and returns. A full reseal deals with it and your cleaning team stops chasing it. Halls, stores and units around places like Hampers Green may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.

Honest limits

A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be any of the following:

  • Leaks through tanking or membranes below the finishes
  • Vanity carcasses that have swollen
  • Mould caused by poor ventilation, which will return until the extract is fixed

If in doubt, ring 01277 525 020 or email drawings and photos and we’ll say what we think.
