Remedial sealant & repairs in Downend, West Berkshire
Remedial sealant for Downend, by sealant specialists with 20+ years’ experience. Rated 4.9 on Google from 180+ five-star reviews.

- Caulk or the wrong sealant used in a wet area
What happens if it’s left?
Remedial work takes longer than a straight reseal, but rarely a lot: the work takes a few hours for most joints, depending on how much old sealant has to come out. Compared with chasing the same leak every few months, it’s time well spent. Where a wall is exposed, as many are in small places like Downend, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
What it costs depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before any work starts, so you know where you stand.

How we handle remedial sealant in Downend
Getting old sealant out properly is slow, careful work. Every layer is cut out, the residue cleaned off and the joint degreased, taking care not to scratch the surfaces around it. Only then can new sealant bond. We’re often asked to deal with floor or wall movement joints that have failed and repeat leaks from the same joint, across leaking tray & enclosure joints, failed movement joints and mouldy bath & shower sealant.
For a small place like Downend, remedial sealant is planned like any other job: the journey and access are simply agreed in advance. In the bathroom or kitchen, the work is the same as in any town.
Our work is backed for twelve months, in Downend and everywhere else we cover.

Common questions in Downend
Is there a guarantee on remedial sealant in Downend?
Every job comes with our one-year guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
Is Downend in your area for remedial sealant?
Yes, Downend is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or email us and tell us what needs doing, and we’ll send you a clear quote.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Can I choose the sealant colour?
Usually, yes. White, clear and grey are common, and other colours are available for many products, and we will agree it with you first.
Can I do it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Someone sealed over the old bead. Can you fix it?
Yes. It’s slower than a standard reseal, because every layer has to come out cleanly, but it’s the only way the new joint will last.
Do you remove the old sealant?
Yes, every time. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
My shower still leaks after a reseal. Can you sort it?
Yes. All the sealant comes out, we find out why it failed, and the joint is resealed properly.
What we cannot put right
We will always be straight with you, so here’s what new sealant won’t do:
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- Water damage behind tiles that needs a tiler
- A tray or bath that’s cracked
If you are not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer before booking.
What we seal
- Expansion joints
- Leaking tray & enclosure joints
- Failed movement joints
- Mouldy bath & shower sealant
- Botched or over-sealed joints
- Shrunken worktop sealant
How the visit works
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and tidy away. It generally takes a few hours, depending on how many layers have to come out. Somewhere like Downend 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.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Old beads and residue are removed down to clean surfaces.
- We treat any mould and dry the joint thoroughly.
- We reseal with a product suited to the joint, backed where needed.
- The joint is tooled and you are told about anything else we found.
Getting ready for the visit
- Let us know about parking restrictions
- For business premises, tell us about site rules or sign-in
- Mention any leaks or damp you’ve noticed

Aftercare tips
A little care helps the new joints last. We recommend:
- Don’t wait for a small gap to become a leak
- Keep an eye on the ceiling below the bathroom
- Keep movement joints clear of mortar and paint
- Air the bathroom so the sealant can dry
If we’ve found a cause, such as a loose tray or a leaking waste, get it fixed, or the new joint may fail again.
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.
Surface by surface
Windows & doors
Smeared or badly matched mastic can be cut out and redone neatly, in a colour that suits the frame.
Worktops & kitchens
Kitchen joints hold grease and residue, so we spend extra time cleaning before resealing.

DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

When to call us in Downend
Joints that move need sealant that can stretch. A bath that flexes, a tray that rocks or a building joint that opens and closes will split a rigid or thin bead.
The most common problems we see are:
- Smears and lumps from a botched reseal
- Movement joints that have split or pulled away
- Kitchen joints letting water behind the worktop
- Dark patches showing through the sealant
In the older streets around Church of St Mary, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.
