How we handle washroom sealing in Donnington
We reseal washrooms and wet areas in offices, hotels, schools, universities, gyms, healthcare buildings and care homes, along with staff kitchens and tea points. Product and method follow how hard each area is used and cleaned. We work on kitchens and tea points, accessible toilets and changing rooms and showers, trays and wet room floors, and what we are called in for most is stained sealant around pans and urinals and mould spotting along silicone joints. A single leaking joint is often how a building in Donnington first comes to us: we look at the rest while we’re there and tell you what we find.
In and around smaller places like Donnington, washroom work is often in halls, pubs, primary schools, care homes and holiday accommodation. Mould gets into sealant in any washroom that doesn’t dry out, and once it’s in, the sealant is replaced.
We stand by our work: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

Should maintenance staff do it?
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Advice
Different surfaces, different methods
Urinals and WC pans
Floor joints around WC pans are often forgotten. They are checked with everything else.
Changing rooms and gyms
Shower areas, wet floor edges and vanity areas all have sealant joints, and we survey them together.
When it isn’t the sealant
A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is any of the following:
- Fittings that move too much to hold a bead
- Leaks through tanking or membranes below the finishes
- Swollen or delaminated boards behind panels or vanity tops
Not sure which it is? You can give us a call on 01277 525 020 or send photos by email and we will tell you honestly before you book.

- Vanity units and basins
- IPS panels and cubicles
- Accessible toilets and changing rooms

What we are called out for in Donnington
Cubicle panels, IPS panels and vanity units flex when people lean on them or doors are slammed, and shower trays shift under foot. If the joint wasn’t laid to take that movement, it tears or peels away.
What tends to prompt an enquiry:
- Discoloured joints around urinals and WC pans
- Users noticing mouldy joints
- Failed sealant in a tea point or staff kitchen
- Sealant stained black around basins and showers
Toilets at colleges like Newbury College, 2.5 miles south of Donnington, take heavy use from students and staff alike.

Common questions from Donnington clients
Is Donnington off your patch?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.
Can you work around term dates at a campus such as Newbury College?
Yes, holiday working periods are the norm on campus jobs. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
What happens if old sealant might contain asbestos?
Managing asbestos is the dutyholder’s responsibility, so we will ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
Do you need to remove the old sealant?
The whole of the old bead is removed and the surfaces cleaned before resealing. That’s what makes the new joint last.
Do you work in hospitals, clinics and care homes?
Yes, healthcare and care settings are part of our work. Any records you need are confirmed with the quote.
Does weather matter for sealant work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
