Washroom sealing for Kidlington sites

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

What the job involves on each surface

Wet-room floors and floor-to-wall joints

Changing rooms and accessible showers often have wet floors, so their perimeter joints get close attention.

Urinals and WC pans

The joint between a pan and the floor is easy to overlook. We include them in the survey.

Washroom sealing in Kidlington, done properly

Accessible toilets, shower rooms and changing rooms have joints that work harder than most: shower trays, wet-room floor edges, basins and floor-to-wall junctions. Gaps in those places let water get under the floor or behind panels, so we look at them closely. If you’re dealing with sealant laid over old silicone and now peeling and mould spotting along silicone joints, we can put it right. Most enquiries from Kidlington start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

In a smaller place such as Kidlington, commercial washrooms tend to be in schools, pubs, cafés, surgeries, care homes and sports clubs. They don’t need a big crew, but they do need old sealant fully cut out before anti-mould silicone goes on.

Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Common problems we fix in Kidlington

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

It’s worth sending us details if you spot any of the following:

  • Sealant laid over old silicone and now peeling
  • Mould spotting along silicone joints
  • Failed joints along IPS and cubicle panels
  • Shower tray joints that have opened up

For a campus such as University Field Station, 2.9 miles to the south-west of Kidlington, showers in residences and washrooms in teaching blocks can be programmed around term dates.

What your quote should include

  • How the joint faces will be prepared and primed
  • Their public liability cover
  • Will failed sealant be removed rather than covered?
  • Their approach to joint depth and backing

How to choose a sealant contractor

How a job runs

At the end of each section, we remove the tape, clean down and inspect every joint, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. If neighbouring businesses or buildings around Kidlington need work too, visits can be combined. Tell us your site hours and we will plan around them.

  1. Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
  2. A phasing plan keeps part of the building’s facilities in use at all times.
  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.

Getting the site ready

  • Have the specification and drawings to hand
  • Warn occupants and staff about the work
  • Flag any permit to work we’ll need

Keeping the joints sound

Once the work is signed off, a little attention goes a long way:

  • Note failing joints building by building
  • Squeegee showers and trays after busy periods
  • Brief cleaning staff to treat joints gently
  • Add sealant joints to planned maintenance checks

Ask your cleaning team to use gentle products and soft cloths on sealant. Aggressive descalers, solvents and scouring pads shorten its life and give mould a start.

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.

Cost factors for washrooms and wet areas

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

  • Site requirements such as inductions and permits
  • Any access equipment needed
  • Location, for remote and island sites
  • Phasing around occupants

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

Details that help us quote

Diagnosis starts before we arrive. Let us know:

  • Your programme or deadline
  • Whether an asbestos survey exists
  • Rough lengths or quantities, or drawings if you have them
  • The postcode of the building

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

Leave it or put it right?

A tired-looking washroom doesn’t always need a refurbishment. Where tiles, panels and fittings are sound, new sealant may be enough to put it right for now. For buildings in places like Kidlington, one well-planned visit beats several small ones, so it’s worth dealing with every failing joint at once.

The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

What you get with us

  • Work carried out by CSCS-carded applicators
  • Fully insured
  • Colours confirmed for the specified product
  • Coloured sealants to suit the setting, where available

Sanitary sealant for Kidlington buildings

At about 56 miles from central London, Kidlington is within reach of the capital. Business park offices have washrooms in daily use by staff, so we work a block of facilities at a time. A 2-mile radius around Kidlington takes in several hotels. Hotel en suites take daily use, and tired silicone at trays and basins is one of the first things guests notice. Rooms are done in turn so most stay available.

Halls linked to places like Church of St Mary host groups all week, which is hard on kitchen and toilet sealant. At a hospital like Acland Hospital, which lies south of Kidlington, patient and staff washrooms are best done in short phases agreed with the ward.

Your questions answered

Will our hotel in Kidlington need to close for the work?

Almost never. The work is phased so most rooms stay available. Tell us your quiet periods and access windows and we’ll plan around them.

Is a hospital such as Acland Hospital somewhere you can work?

Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Will cleaning remove black mould from sealant?

Normally not. The mould is inside the silicone, so it comes back however often it’s cleaned. Replacing the bead is the lasting answer.

What’s the quickest route to a quote?

You can use the quote form on this site; alternatively, call the office on 01277 525 020 or use the quote form. Photos, drawings or a joint schedule help us quote quickly.

Is there a guarantee on the work?

A 12-month guarantee covers the work. It applies to our workmanship, not to plumbing leaks or damp from poor ventilation.

Is Kidlington in your area?

Yes. Sites across Kidlington are covered.

Do you offer coloured sealant?

In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.
