Washroom sealing near Walmer

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

General trades versus a specialist

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.

Washroom sealing in Walmer

Not every silicone belongs in a washroom. Sanitary silicone contains additives that resist mould, and neutral-cure versions avoid the damage acetoxy types can do to some metals, stone and mirror backings. Where food contact is possible, we use a hygienic, food-safe grade. If you have failed sealant in a tea point or staff kitchen and users noticing mouldy joints, we can put it right, whatever the surface. A single leaking joint is often how a building in Walmer first comes to us: 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 Walmer work hard on their joints. Smooth, sealed joints at worktops, sinks and wall cladding make cleaning easier, using a food-safe product near food preparation.

We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application.

Maintenance after handover

After handover, a little attention goes a long way:

  • Keep extract fans working and vents clear
  • Act on the first split you see at a shower tray
  • Keep a record of which washrooms need attention
  • Clear standing water from shower floors where possible

Include sealant joints in your planned maintenance checks. Check for mould spots, splits, lifting edges and open joints at trays, basins and urinals and photograph anything new.

Inspectors look at whether kitchen surfaces can be kept clean. Resealing sinks, worktops and splashbacks before an inspection is a simple step.

On site: what to expect

Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. Work in places the size of Walmer is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.

  1. We survey each room, count the joints and note anything behind them that needs another trade.
  2. We agree which rooms close and when, so users always have somewhere to go.
  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. We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
  6. You get a reopening time for every room, with signage left up until then.

What we need from you

  • Arrange parking or a loading space
  • Share the asbestos register for older buildings
  • Send your site hours and access windows

Busy facilities in and around Walmer

Walmer lies within about 1 mile of the sea, and places by the sea often rely on visitors, so their hotels and holiday lets see heavy seasonal use. Showers and en suites in constant use are where silicone moulds and splits first, which is why off-season resealing makes sense. A 2-mile radius around Walmer takes in a good number of hotels. En suite bathrooms, staff changing rooms and kitchens all need their sanitary silicone renewed in time. Rooms are done in turn so most stay available.

At a hotel such as Queens Hotel, 1.1 miles to the north of Walmer, the quieter weeks are the time to reseal bathrooms. At a school such as The Downs Church of England Primary School, changing rooms and kitchens need cleanable joints as much as the toilets. For a hall at a building such as St Mary's Church, resealing the kitchen and toilets can be fitted between bookings.

Different surfaces, different methods

IPS and cubicle panels

A panel that has already swollen won’t be fixed by sealant, and any we come across will be pointed out.

Healthcare and care settings

Assisted bathrooms and accessible toilets get heavy use, so their joints often need renewing sooner.

Quoting for work in Walmer

Sealant work doesn’t have a standard rate, because every site is different. What we take into account:

  • Any access equipment needed
  • Phasing around occupants
  • Removal of failed or old sealant
  • The total length or number of joints

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

Before you send an enquiry

It doesn’t need to be a full survey. These details are enough to start:

  • The postcode of the building
  • Asbestos survey details if the building is older
  • Access details, including height
  • Rough lengths or quantities, or drawings if you have them
