Remedial sealant in Sunningwell
A joint that keeps failing usually has a reason. Movement, the wrong product or a leak from somewhere else will beat any new bead. Finding that cause comes before any new sealant. If you have floor or wall movement joints that have failed and leaks that keep coming back after resealing, we can put it right, whatever the surface.
Homes around Sunningwell are mostly houses and cottages rather than flats, some with bathrooms tucked into older rooms or extensions. The work is the same as anywhere: old material cut out, joints cleaned and a fresh finish laid.
Whatever the size of the job, it’s backed by our 12-month guarantee in Sunningwell and across Oxfordshire.

When it is not the sealant
To be straight with you, there are a few things sealant won’t fix:
- Older mastics that may need an asbestos check before removal
- Water damage behind tiles that needs a tiler
- Cracks in the fitting rather than the joint
If in doubt, call 0345 464 0079 or email us and we will say what we think.

How to look after the new joints
Looking after new joints is easy, and it makes a real difference:
- Keep bleach and abrasives off the bead
- Keep an eye on the ceiling below the bathroom
- Find out why the sealant failed first
- Have loose fittings fixed before resealing
Where we’ve pointed out another fault, have it put right, because the new sealant can’t hold back a problem underneath.
Leaks through failed sealant grow over time. Every shower or downpour sends more water through, into floors, walls or ceilings. Early action keeps it to a sealant job.
DIY versus a professional finish
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
Sunningwell: your questions answered
I let a flat near Radley station. Can you help?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear price.
Is Sunningwell in your area for remedial sealant?
Yes. Our work covers London and the South East, and Sunningwell is part of that. You can ring 0345 464 0079 or email us and let us know what needs doing.
How long will it take to strip and reseal the joint?
It takes a few hours for a typical bath or shower, longer where several layers have been applied. We’ll give you a timescale when we quote.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Do you fix expansion and movement joints?
Yes. Failed movement joints are cut out and resealed with backing and a flexible sealant suited to the movement.
Do you work for hotels and businesses?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. Working times can be discussed when we quote.
Can you do several jobs on one visit?
Yes, we can. More than one area can go on one quote.
Someone sealed over the old bead. Can you fix it?
Yes. We remove every layer; over-sealing fails because silicone will not bond to silicone.
What affects the cost of remedial sealant
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Working hours on commercial sites
- How many rooms, windows or areas are involved
- Any mould that needs treating
- How much old sealant there is and how hard it is to remove
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, call 0345 464 0079 or drop us an email for an honest opinion and a quote.
Helping us quote
You don’t need to know the technical terms. It helps if you can tell us:
- Whether it’s a home or a business
- Any previous sealing or DIY work
- Where the property is
- The rough size of the job
It all starts with a short chat. Describe the problem, the location and the size of the job. When it suits you, call 0345 464 0079 or drop us an email.
What we do, step by step
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The work itself takes a few hours for most joints, depending on how much old sealant has to come out, including the tidy-up. For a village or hamlet like Sunningwell, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We look at how the sealant has failed and check for movement or a leak path.
- Every layer of old sealant is cut and cleaned out.

When to call us in Sunningwell
Even good sealant ages. Mould grows into the silicone, the surface hardens and the bead shrinks, faster where ventilation is poor. Then the only fix is removal and a new bead.
The problems people usually mention when they call are:
- Worktop sealant that has shrunk and split
- Floor or wall movement joints that have failed
- A shower that leaks however often it’s resealed
- Dark patches showing through the sealant
Schools such as Sunningwell Church of England Primary School are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

Remedial sealant in Sunningwell: local notes
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Letting a property close to Radley station? Then failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. If you live in an older home near Church of St Leonard, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.
