Remedial sealant in Cornish Hall End
Remedial work is what we do when sealant has failed or been done badly. New sealant over old, smeared beads, unsuitable products and hidden mould all need stripping out before the joint can be done properly. We are often asked to deal with beads that never stuck properly and worktop sealant that has shrunk and split, on mouldy bath & shower sealant, failed movement joints and leaking tray & enclosure joints.
Somewhere as small as Cornish Hall End, homes tend to be cottages, farmhouses or converted buildings, with some newer houses too. Movement in older walls and floors tends to show first as cracked grout or split sealant.
A 12-month guarantee comes as standard.

Signs you need remedial sealant in Cornish Hall End
Movement tears sealant that is not designed for it. Flexing baths, rocking trays and building movement joints split any bead that is too stiff or too thin.
People generally contact us after spotting something like this:
- Sealant peeling off a dusty or damp surface
- Smears and lumps from a botched reseal
- Sealant applied over old sealant that has lifted
- Caulk or the wrong sealant used in a wet area
For an older house near a landmark such as St John the Evangelist Church, timber floors under older bathrooms flex, so joints need a sealant that moves with them.

The process
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, do the work and clear up. It normally takes a few hours, depending on how many layers have to come out. For a village or hamlet like Cornish Hall End, 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.
- 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.
- Mould is treated and the joint dried.
- The right product goes in, with backing where the joint moves.
- We finish neatly and point out anything that needs another trade.
Getting ready for the visit
- Keep children and pets away from the work area
- Try not to wet indoor joints just before the visit
- Tell us about any water getting in

Questions from Cornish Hall End
Is Cornish Hall End within the area you cover?
Yes, Cornish Hall End is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you do remedial sealant in Cornish Hall End?
Yes, Cornish Hall End is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear price.
How long before the joint can be used?
That depends on the sealant used, so please follow the time we give you when we finish.
What does remedial sealant cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we’ll talk you through it.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we are fully insured.
Do you remove the old sealant?
Yes, always, and completely. New silicone does not stick to old silicone, so the joint is cleaned back first.
Do you have insurance?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Do you work for letting agents?
Yes, often. Several properties can be quoted together, and between tenancies is a good time for the work.
When something else is needed
New sealant can’t fix everything, and we’d rather say so up front. Sealant won’t put right:
- A leaking trap, valve or supply pipe
- Cracks in the fitting rather than the joint
- Tiles that have come away from the wall
If you are not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer.
What we seal
- Mouldy bath & shower sealant
- Expansion joints

For landlords and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
What happens if it’s left?
Hidden water does the most damage: soaked floorboards, ceiling stains below and blown plaster. By comparison, sorting the joint is quick. Where a wall is exposed, as many are in small places like Cornish Hall End, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.
