How we handle washroom sealing in Ewelme
You can’t shut every toilet in an office, school or hotel at once. Work is phased by room or by section, so staff, guests or pupils always have somewhere to go. Tell us your site hours and access windows and we’ll plan around them. If you have users noticing mouldy joints and split or peeling sealant at shower trays, we can put it right, on vanity units and basins, urinals and WCs and IPS panels and cubicles alike. Whether you call it commercial sealant work, mastic application or joint sealing, in Ewelme it comes down to the same thing: the right product in a properly prepared joint.
Halls and community buildings near places like Ewelme are used by different groups through the week, and their toilets and kitchens show it. Resealing sinks, worktops and WCs with anti-mould silicone keeps them clean and watertight.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Leave it or put it right?
Open or mouldy joints are hard to keep hygienic, and in kitchens, clinics and schools that is a real concern. Sound, smooth joints are much easier to keep clean. For buildings around smaller places like Ewelme, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Washroom sealing in Ewelme: the local picture
Ewelme is about 43 miles from central London, in a commuter belt where offices and business parks are common. Office toilets in the commuter belt are in use from first arrivals to last departures, which is why the work is phased.
Where you’re responsible for a hall attached to a building such as Church of St Mary, its kitchen and toilets need sealant that stays cleanable. At a school such as Ewelme CofE Primary School, changing rooms and kitchens need cleanable joints as much as the toilets.
Ewelme is about 8 miles east of Didcot, in Oxfordshire. Across the OX10 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Our Oxfordshire coverage takes in 423 places, from busy centres to rural villages. Our Oxford page has more on work in that area, about 11 miles away.

Questions about Ewelme
What paperwork can you provide for a job in Ewelme?
Whatever your site asks for, from RAMS to CSCS details, is confirmed when we quote. We are CHAS accredited and a Constructionline member, with £5m public liability insurance and CSCS-carded applicators.
Is Ewelme too small for you to travel to?
No. Places such as Ewelme are covered as much as the big towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
Is old silicone taken out first?
We always remove it. New silicone won’t stick to the old, so sealing over it soon peels.
What will the job cost?
Every job gets its own fixed quote. For yours, call 01277 525 020 or email drawings and photos.
Can you quote from photos?
It depends on the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.
Will cleaning remove black mould from sealant?
Normally not. The mould is inside the silicone so cleaning only lightens it for a while. Replacing the bead is the lasting answer.
Are you CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
What else we do in Ewelme
Building owners, agents and FMs in Ewelme
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.
Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.
What we can’t put right
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Panel boards already damaged by water
- Loose panels, vanity units or tiles, which need fixing first
- A dripping waste or valve behind a panel
If you are not sure, just call the office on 01277 525 020 or send details through our quote form and we’ll give you a straight answer before you book.
Surfaces we seal
- Showers, trays and wet room floors
- Vanity units and basins
- Accessible toilets and changing rooms
- Urinals and WCs
- Kitchens and tea points
- IPS panels and cubicles
When to call us in Ewelme
Mop buckets, trolleys and knocks from users damage joints near the floor at skirting lines, urinal bases and around pans.
Things that typically lead to an enquiry:
- Shower tray joints that have opened up
- Washrooms that look worn because of the sealant
- Urinal joints that look unhygienic
- Sealant laid over old silicone and now peeling
Units at estates like Watlington Industrial Estate (3 miles north-east of Ewelme) have welfare blocks whose showers and toilets see shift after shift.
Before you book anyone
- Are they CHAS accredited or on Constructionline?
- Will failed sealant be removed rather than covered?
- Which product they’ll use, and why it suits the joint
- How they’ll work around occupants
How the job changes by surface
Wet-room floors and floor-to-wall joints
Wet-room floors and the joints where flooring turns up the wall need to stay sound. We reseal the floor-to-wall junctions and around drains where sealant is used.
IPS and cubicle panels
Swollen or delaminated boards need replacing and we will point out any we see.
Our process
On arrival, 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 any cutting starts, and the work typically takes a few hours for one toilet block, with bigger buildings phased across a number of visits. If others near Ewelme need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.
- First, the phasing is agreed so facilities stay open.
- Leaks, loose panels or damp are pointed out first.
- Failed sealant and residue are stripped out.
- We reseal with the grade suited to each area.
- We confirm reopening times for each washroom.
Before we start on site
- Tell staff and tenants when we will be in
- Send your site hours and access windows
- Confirm the product named in the specification
