Need washroom sealing in Sunnymead?

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Looking after the joints

Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:

  • Clear standing water from shower floors where possible
  • Keep washrooms out of use until we say the sealant has cured
  • Keep a record of which washrooms need attention
  • Avoid scourers and harsh descalers on silicone

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

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

Washroom sealing in Sunnymead

Black spotting along a sealant bead is not a cleaning problem. The mould has rooted into the silicone itself, which is why it comes back however often it is treated. Only replacement gets rid of it for good. The enquiries we see most involve stained or open joints at kitchen sinks and worktops and failed sealant behind washroom basins, across IPS panels and cubicles, vanity units and basins and urinals and WCs. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Sunnymead it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Jobs in a smaller place such as Sunnymead are often one building: a school’s toilets, a café kitchen, a surgery’s washrooms. Photos of each area help us plan the visit and bring the right sealant.

We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

What we’re called out for in Sunnymead

Sometimes the sealant fails because something behind it is moving or wet: a loose panel, a leaking waste or water coming through the wall. We look for it before resealing and say if it needs a plumber or another trade.

Common reasons buildings call us in:

  • Resealing that didn’t last because the old bead stayed
  • Shower tray joints that have opened up
  • Stained or open joints at kitchen sinks and worktops
  • Open joints along basins and vanity units

For buildings on a site such as Jordan Hill Business Park, which lies north-west of Sunnymead, washrooms and tea points can be resealed in phases through the working week.

What your quote should include

  • How joint depth will be controlled
  • Their plan for phasing and protecting the area
  • What the guarantee covers, and for how long
  • Will CSCS-carded applicators be on site?

Questions to ask before you appoint anyone

Different surfaces, different methods

Urinals and WC pans

Joints around urinals and WC pans take splashes, cleaning chemicals and knocks. Stained or split joints here trap smells and make the room look neglected.

Changing rooms and gyms

Changing rooms in gyms and leisure centres stay wet and warm, so mould is a constant battle. We use anti-mould sanitary silicone throughout.

How a job runs

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. For a job in Sunnymead, the main thing is a clear picture of the work. A fixed quote follows.

  1. We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
  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. Joints are cleaned, degreased and dried before sealing.
  5. A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
  6. You get a reopening time for every room, with signage left up until then.

Preparing the site

  • Share your working hours and any access restrictions
  • Share the asbestos register for older buildings
  • Point out any areas we must not close

Toilets, showers and kitchens around Sunnymead

Sunnymead is about 54 miles from central London. Office washrooms on business parks see heavy weekday use, so we phase work to keep some facilities open. A good number of hotels sit less than 2 miles from Sunnymead. Each has en suites, back-of-house toilets and kitchens with sealant that moulds and splits. Rooms are done in turn so most stay available.

Customer toilets in retail centres such as Clarendon Shopping Centre (to the south of Sunnymead) rarely close, so resealing is phased. Healthcare washrooms on sites such as John Radcliffe Hospital, 2.5 miles south-east of Sunnymead, are resealed area by area, under the site’s own infection-control rules.
