Washroom sealing for Coley Park sites

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

Commercial clients in Coley Park

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

We work for building owners and managing agents on everything from one building to a spread of sites around Coley Park. Several sites can go on one quote, so there’s one set of paperwork to deal with.

Washroom sealing in Coley Park

From one staff toilet in Coley Park to washrooms across a whole estate, we work the same way: send details, get a fixed quote, we seal, guaranteed. Photos and a rough count of basins, urinals, showers and cubicles help us give a quick quote, or we can arrange a visit. Site teams most often ask us about sealant lifting along a tray edge and failed joints along IPS and cubicle panels, on kitchens and tea points, vanity units and basins and IPS panels and cubicles. A specialist sealant contractor works differently from a general builder: in Coley Park, that means joint design, primers and backing rod as standard.

Jobs in a smaller place such as Coley Park 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.

Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

What sealant work can’t fix

A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is any of the following:

  • Vanity carcasses that have swollen
  • Water escaping beneath the floor rather than through a joint
  • Water from plumbing, not from a joint

If you are not sure, just call 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer.

Joints and surfaces we work on

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

Signs you need washroom sealing in Coley Park

Low-level joints get hit by mop buckets, cleaning trolleys and feet, especially at floor edges and around urinals and WC pans.

Clients typically get in touch after noticing something like this:

  • A new bead over an old one coming away
  • Sealant lifting along a tray edge
  • Open joints along basins and vanity units
  • Failed joints along IPS and cubicle panels

At a hotel such as Crescent Hotel, under half a mile to the north-east of Coley Park, the quieter weeks are the time to reseal bathrooms.

Questions to ask before you book

  • How they handle RAMS and site documents
  • How joint depth will be controlled
  • Do they follow the manufacturer’s priming guidance?
  • Whether old or failed sealant will be cut out, not overlaid

How to choose a sealant contractor

How a job runs

When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work normally takes a few hours for one toilet block, with bigger buildings phased across a number of visits. If neighbouring businesses or buildings around Coley Park need work too, visits can be combined. Mention the building’s opening times and we will work within them.

  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. We strip out the old bead and clean off the residue left behind.
  4. Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
  5. A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
  6. Rooms reopen after the product’s cure time, and we move to the next.

What we need from you

  • Explain the parking and delivery arrangements
  • Send any specification or drawings in advance
  • Warn occupants and staff about the work

Coley Park: questions and answers

Would you work within a site like Berkshire Independent Hospital?

Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Does a hotel in Coley Park need to shut while its sealant is renewed?

Rarely, if ever. We take a few rooms out at a time. We agree the order of rooms and the timings with you before we start.

How do you choose the sealant?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Are your applicators CSCS-carded?

Yes. If you need card details for site access, let us know and we will send them with the quote.

Is it possible to just clean mouldy silicone?

Surface cleaning won’t reach mould that has rooted into the bead. We replace the sealant with an anti-mould sanitary grade and point out if ventilation is part of the problem.

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

We always remove it. Fresh silicone can’t key to an old bead so a bead over the top fails quickly.

How do I request a quote?

The quote form is the simplest route, though you can also call 01277 525 020 or email the details over. Photos, drawings or a joint schedule help us quote quickly.

Should maintenance staff do it?

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Maintenance after handover

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Don’t leave trays and floors sitting wet
  • Brief cleaning staff to treat joints gently
  • Mention any site permits or estates rules at quote stage
  • Act on the first split you see at a shower tray

Each room goes back into use only when the sealant has cured enough. You will be told when showers and basins can be used again, and it helps if signs stay up until then.

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

Office toilets in the commuter belt are in use from first arrivals to last departures, so we work a block of facilities at a time. The area within 2 miles of Coley Park holds plenty of hotels. Each has en suites, back-of-house toilets and kitchens with sealant that moulds and splits. We work a handful of rooms at a time, so the hotel keeps letting the rest.
