Sands End Remedial Sealant
We cover Sands End for removing failed, mouldy or leaking sealant and putting it right. Old material cut out, joints cleaned and sealed neatly and a one-year guarantee.
- Decorators’ caulk around a bath or shower
- Beads that never stuck properly
- Repeat leaks from the same joint
Why deal with it now?
Mould under a bead cannot be reached by cleaning. Removal is the only way to get at it. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Sands End, the repair is bigger than a sealant job.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or drop us an email.
Why Sands End customers choose us
- White, clear, grey or another colour, product permitting
- An ARBOMaster approved applicator

Remedial sealant for homes and businesses in Sands End
If a joint has been resealed and is leaking again, it’s worth a proper look. Send pictures when you call 0345 464 0079 or send us an email, and say how long ago it was last done. If you have torn expansion joints and products that weren’t meant for the joint, we can help, on botched or over-sealed joints, mouldy bath & shower sealant and leaking tray & enclosure joints alike.
London’s water is hard, so limescale builds up along sealant lines, in grout and on fittings. In Sands End, remedial sealant is as much about a room looking cared for as about keeping water out.
We stand behind the work with a one-year guarantee, so you’re covered after we have gone.

Honest limits
New sealant can’t fix everything, and we’d rather say so up front. It won’t solve:
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- Tiles that have come away from the wall
- A bath, tray or worktop that moves until it’s properly fixed
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly.
What we seal
- Mouldy bath & shower sealant
- Leaking tray & enclosure joints
- Botched or over-sealed joints
- Shrunken worktop sealant
- Failed movement joints
- Expansion joints

What else we do in Sands End
What affects the quote in Sands End
There’s no set price list, because no two jobs are the same. What we look at:
- How many rooms, windows or areas are involved
- The number and length of the joints
- The product the joint needs
- The old material and how stubborn it is
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.
Helping us quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- Roughly how big the job is
- Photos by email, if that’s easy
- Where the property is
- What the problem is, such as mould, gaps, leaks or cracking
We quote each job on its own, so the first step is telling us about yours. Just ring 0345 464 0079 or drop us an email with the details.

Common questions in Sands End
Do you work for landlords with property near Imperial Wharf station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear quote.
Can parking be tricky for a visit in Sands End?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
Where are you based?
Mr Mastic is based in Crawley. We cover Sands End and the rest of Greater London, along with the rest of our area.
Do you do commercial work?
Yes. We work in offices, washrooms, hotels and other commercial premises. We can talk about working times when we quote.
Can you remove old sealant without damaging the bath?
Yes, with care. We cut and lift the old sealant with tools suited to the surface, then clean off the residue. Any existing damage is pointed out before we start.
Can you take off two layers of silicone?
Yes. Both layers come out; new silicone does not bond to old silicone, which is why over-sealing fails.
Can you quote for more than one area?
Yes, we can. More than one area can go on one quote.
Can I do it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
What happens on the day
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours for most joints, depending on how much old sealant has to come out. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.
- We protect the surfaces around the joint.
- Every layer of failed sealant is stripped out.
- We clean and degrease the joint and look for signs of movement or water.
- Once dry, a suitable sealant is applied and tooled.
- We give you the cure time and explain what caused the failure.
How to prepare
- Mention if the joints have been sealed before
- Mention any sign-in or site rules at work premises
- Tell us if parking is tricky

Related advice
When to call us in Sands End
How a joint is built matters as much as the product. A bead bonded on three sides, or laid too thick, can’t flex, so it tears when the joint moves. Backing rod or bond-breaker tape prevents it.
The problems people normally mention when they call are:
- Gaps opening along the back of the worktop
- Products that weren’t meant for the joint
- Sealant that came away because the surface wasn’t prepared
- A shower that leaks however often it’s resealed
Sands End is in London, so parking needs planning: let us know about parking bays, permits or a driveway.
Before booking anyone
- How hidden problems are handled
- Whether all the old sealant comes out first
- Which sealant they’ll use, and why
- Whether you can choose the colour
DIY versus a professional finish
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
