How we handle washroom sealing in Great Coxwell
Closing all the facilities in a building isn’t an option. We phase the work one washroom, one bank of cubicles or one changing room at a time, so there are always facilities in use. Give us your site hours and access windows and the phasing is planned around them. The enquiries we see most involve a new bead over an old one coming away and stained or open joints at kitchen sinks and worktops, on showers, trays and wet room floors, accessible toilets and changing rooms and IPS panels and cubicles. For commercial sealant work in Great Coxwell, you deal with one contact from quote to sign-off, whether it’s one building or several.
Smaller places such as Great Coxwell still have commercial washrooms and kitchens: in halls, pubs, schools, care homes and farm-based businesses. Mould gets into sealant in any washroom that doesn’t dry out, and once it’s in, the sealant is replaced.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Questions about Great Coxwell
Does a hotel in Great Coxwell 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.
Is a smaller place like Great Coxwell outside your area?
Not at all. Great Coxwell is within our area. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.
Do your applicators hold CSCS cards?
Yes. If you need card details for site access, let us know and we’ll send them with the quote.
Which sealant will you use?
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.
Does weather matter for sealant work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
How do we ask for a quote?
You can use the quote form on this site; alternatively, ring 01277 525 020 or email drawings and photos. Include photographs or drawings if you have them.
How the quote is worked out
Before we quote, we look at:
- Whether old sealant has to be cut out first
- Any access equipment needed
- Site requirements such as inductions and permits
- Travel to remote or island sites
The price depends on the quantity of joints, how much old material needs removing and how the joints are reached. Call for a fixed quote once you have the details.
Before you send an enquiry
Whether it’s one area or a whole building, these details speed things up:
- Whether an asbestos survey exists
- Anything awkward about access or site hours
- Clear photographs of the problem areas
- Drawings or a marked-up plan, if available
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, phone 01277 525 020 or use the quote form.

Commercial washrooms in Great Coxwell
Several hotels sit less than 2 miles from Great Coxwell. En suite bathrooms, staff changing rooms and kitchens all need their sanitary silicone renewed in time. The work can go floor by floor, agreed with housekeeping. Great Coxwell has two care or nursing homes no more than 2 miles away. In care settings, wet rooms, assisted bathrooms and en suites rely on clean, sound sealant. Each room is kept out of use only as long as the sealant needs.
Where you’re responsible for a hall attached to a building such as Church of St Giles, its kitchen and toilets need sealant that stays cleanable. Office toilets at parks like Faringdon Business Park, under half a mile south-east of Great Coxwell, take steady weekday use, and mouldy silicone soon shows.

Surface by surface
Showers and trays
A tray flexes every time it’s used and is constantly wet. Tray perimeters are a frequent source of leaks.
Wet-room floors and floor-to-wall joints
We seal the visible joints; we don’t install or repair waterproofing below, and we’ll say if the trouble looks to be beneath the floor.
Why it’s worth doing now in Great Coxwell
Gaps and mould in joints give dirt and bacteria somewhere to sit which matters most in healthcare, food and education settings. A smooth, sealed joint can be cleaned properly. For buildings around smaller places like Great Coxwell, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Our process
On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself usually taking between a morning and a week or so, set by the number of rooms and the phasing you need. If others near Great Coxwell need work, visits can be combined. You’ll have a fixed quote before work starts.
- We agree which washrooms close and when.
- Anything behind the joints that needs another trade is flagged.
- Old sealant is stripped and the faces prepared.
- The right sanitary or food-safe sealant is applied.
- We give you a reopening time for every room.
Getting the site ready
- Tell us what induction or permit system the site runs
- Clear stock, furniture or equipment away from the joints
- Tell staff and tenants when we will be in
Getting a fixed quote
Need a figure for a tender or a budget? Send the scope and any drawings, and we will return a fixed quote that you can work with. For a chat about it beforehand, give us a call on 01277 525 020 or email a schedule or drawings.

What we can’t put right
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Water escaping beneath the floor rather than through a joint
- Mould caused by poor ventilation, which will return until the extract is fixed
- Panel boards already damaged by water
If in doubt, ring 01277 525 020 or email drawings and photos and we’ll say what we think.
Surfaces we seal
- Vanity units and basins
- Accessible toilets and changing rooms
- Showers, trays and wet room floors
- Kitchens and tea points
- IPS panels and cubicles
- Urinals and WCs
Signs you need washroom sealing in Great Coxwell
Much of the failed sealant we remove was applied over old silicone or residue. Silicone won’t adhere to a silicone bead so it peels away quickly.
Common reasons buildings call us in:
- Black mould inside silicone joints that cleaning can’t shift
- Panel joints letting water behind
- Discoloured joints around urinals and WC pans
- Users noticing mouldy joints
Schools such as Faringdon Community College have toilets, changing rooms and kitchens that are best resealed in the holidays.
