How we handle remedial sealant in Duns Tew
If a joint has been resealed and is leaking again, it’s worth a proper look. It helps to have photos when you call 0345 464 0079 or send us an email. We work on failed movement joints, expansion joints and mouldy bath & shower sealant, and people most often call us about dark patches showing through the sealant and torn expansion joints.
Homes around Duns Tew are mostly houses and cottages rather than flats, some with bathrooms tucked into older rooms or extensions. Sealant and grout wear out here just as they do anywhere: everything old comes out before the new sealant or grout goes in.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Duns Tew: your questions answered
Can you do remedial sealant in Duns Tew?
Yes, Duns Tew is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or email us and let us know what needs doing, and we’ll send you a clear quote.
Do you work for landlords with property near Heyford station?
Yes, we work for letting agents and landlords. Just call 0345 464 0079 or email us and tell us about the property, and we will give you a clear price.
What happens if the problem is the tray or the plumbing?
We check for that before we reseal. If the fault is elsewhere, you’ll know before any work is done.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. Our applicators cover Duns Tew.
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.
What should I tell you?
Just the basics: where it is, what you’ve noticed and how we reach it. Then ring 0345 464 0079 or send us an email.
Will the old sealant be removed?
Yes, always, and completely. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Can I do it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
When to call us in Duns Tew
Some joints fail because water is reaching them from behind. A leaking valve, a failed waste or cracked grout feeds water behind the bead, so the silicone goes mouldy or lets go.
It’s worth asking for a quote if you see:
- Dark patches showing through the sealant
- Leaks that keep coming back after resealing
- Wide, uneven beads that look worse than the old ones
- A second bead peeling off the first
Homes close to Church of St Mary Magdalene include some older properties, and older homes can move a little, which is hard on rigid grout and tired sealant.

Why act early in Duns Tew
Repeat failures have a cause. Taking time to find the cause, whether it’s movement, a leak or the wrong product, is what stops it happening again. In a small place like Duns Tew, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Combining jobs into one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

What affects the cost of remedial sealant
There’s no set price list, because no two jobs are the same. The quote depends on:
- Whether old sealant or filler has to be cut out
- Whether there’s mould to deal with
- How easy the joints are to reach
- When we can work, for business premises
Leaving a failed joint normally makes the job bigger, not smaller. If you’re unsure, phone 0345 464 0079 or email us for an honest opinion and a quote.
What we need to know
When you call or email, it’s useful to know:
- How many joints, rooms or windows are involved
- Whether it has been sealed before
- Pictures of the joints, sent by email
- What the problem is, such as mould, gaps, leaks or cracking
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we’ll explain how we’d tackle it. Whenever you’re ready, call 0345 464 0079 or email us.
DIY sealant or a professional job?
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
What we do, step by step
Every visit runs the same way: we check the joints, protect the area around them, do the work and clear up. Most jobs take a few hours, depending on how many layers have to come out. Somewhere like Duns Tew needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided 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.
- Next, any mould is treated and the joint dried.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- Finally we finish the joint and talk you through what we found.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Tell us if parking is tricky
- Plan for the work area to be out of bounds to pets and children

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Never fill a movement joint with mortar or grout
- Look for stains below bathrooms now and then
- Always have old sealant cut out, not covered
- Find out why the sealant failed first
Ventilation keeps mould away from the new bead: run the fan during and after showers, or open a window.
Signs to act on: peeling layers, mould showing through the bead, leaks after showering or cracks in a movement joint. Each one is worth getting looked at.
