Remedial sealant in Banstead, done properly
If a joint fails again and again, something is causing it. A tray that moves, a worktop that isn’t fixed, the wrong sealant or water getting in elsewhere will beat any new bead. Finding that cause comes before any new sealant. If you’re dealing with worktop sealant that has shrunk and split and wide, uneven beads that look worse than the old ones, we can put it right, whatever the surface.
In and around Banstead, older properties sit alongside newer ones. In older homes, walls and floors can move a little more, so the right flexible sealant matters.
You get a 12-month guarantee, the same in Banstead as everywhere else we work.

What we do, step by step
The work is kept neat and contained to the area we are working on. Expect the work to take a few hours, depending on how many layers have to come out, and we tell you how long to leave it before we go. Parking around Banstead is usually easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- 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
- Mention any tricky access
- Let us know about earlier repairs to the joints
- Let us know if you’ve seen damp or leaks

When it isn’t the sealant
Sealant is not the answer to every problem, and we will tell you before work begins. It will not solve:
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- A bath, tray or worktop that moves until it’s properly fixed
- Tiles that have come away from the wall
If you’re not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer.
Joints and surfaces we work on
- Expansion joints
- Botched or over-sealed joints
- Failed movement joints
- Leaking tray & enclosure joints
- Mouldy bath & shower sealant
- Shrunken worktop sealant
Should I try it myself first?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Questions from Banstead
Can you do remedial sealant in Banstead?
Yes. We work across London and the South East, and Banstead is part of that. 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.
Will you come out to Banstead?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Where are you based?
Mr Mastic is based in Crawley. Our applicators cover Banstead.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Do you work for landlords and businesses?
Yes, often. We can quote for several properties at once, and between tenancies is a good time for the work.
I rent my home. Can I book you?
We are happy to deal with the tenant, landlord or agent. Just make sure your landlord agrees.
How long will it take to strip and reseal the joint?
Longer than a simple reseal, because every layer has to come out. Most jobs take a few hours, and we confirm the time with your quote.
Can failed expansion joints be resealed?
Yes. Backing sets the depth and stops the sealant sticking to the back.
Different surfaces, different methods
Leaking trays & enclosures
Where the joints are the problem, every bead is stripped and resealed with anti-fungal sanitary silicone, including the screen profile and tray edges.
Over-sealed & botched joints
Thick, smeared sealant looks messy and hides problems. Taking it back shows what’s underneath, then reseal neatly.
When to call us in Banstead
A lot of failed joints have been sealed over rather than replaced. New silicone cannot stick to the old bead, so the new layer peels, and damp and mould settle between them.
Any of these means the joints need attention:
- Sealant applied over old sealant that has lifted
- Smears and lumps from a botched reseal
- Worktop sealant that has shrunk and split
- Black mould underneath the bead
If you look after a building such as St Anne's Catholic Primary School, we reseal washrooms and kitchens in schools and businesses as well as homes.
What your quote should include
- The length of the guarantee
- Whether you can choose the colour
- What preparation is included
- Whether they seal over old material or remove it

What remedial sealant looks like in Banstead
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.
Letting a property close to Banstead station? Then failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. In the older streets around Church of All Saints, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

Why act early in Banstead
Adding more sealant is the usual quick fix, and it rarely works. It can’t bond to what’s underneath, leaving the leak in place and one more layer to cut out later. In an older home around Banstead, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before we start.
