Remedial sealant for homes and businesses in Stone
Decorators’ caulk in a shower, bathroom silicone on a window, a rigid filler in a movement joint won’t last, however tidy it looks. We take it out and use a sealant made for that joint. We work on shrunken worktop sealant, botched or over-sealed joints and leaking tray & enclosure joints, and common reasons people get in touch are smears and lumps from a botched reseal and sealant that came away because the surface wasn’t prepared.
Around Stone, you will mostly find houses and bungalows, from older cottages to newer builds. Sealant and grout wear out here just as they do in a big town.

Common questions in Stone
I let a flat near Stone Crossing station. Can you help?
Yes, rental work is part of what we do. You can call 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before we start.
Will you come out to Stone?
Yes, Stone is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.
Do you remove the old sealant?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Where do you work from?
Mr Mastic is based in Crawley. We cover Stone and the rest of Kent, along with the rest of our area.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you do not need to watch us work.
Can you remove old sealant without damaging the bath?
Yes. We take our time over removal, particularly on softer surfaces like acrylic.
Will you leave a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Deal with small splits early
- Ask why a joint failed before redoing it
- Keep an eye on the ceiling below the bathroom
- Always have old sealant cut out, not covered
Keep an eye on the joint at first, especially if movement was the problem. Should anything change, ring 0345 464 0079 or drop us an email.
Don’t keep resealing the same joint. Get the cause found first, or the next bead will go the same way.
Can I do it myself?
A DIY attempt does not rule out a professional job. We cut it out and start again.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
How it works
There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the job takes a few hours for most joints, depending on how much old sealant has to come out in most cases. Parking around Stone is usually easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- We protect the surfaces around the joint.
- The botched or failed sealant is cut away completely.
- We clean and degrease the joint and look for signs of movement or water.
- Once dry, a suitable sealant is applied and tooled.
- You get the cure time and our view on why the joint failed.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Let us know about stairs, lifts or work at height
- On commercial sites, let us know about site rules

What else we do in Stone
Stone homes and their sealant
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
If you let a flat or house near Stone Crossing station, a joint that keeps failing is best fixed properly while the property is empty. For an older house near a landmark such as Church of St Mary, older homes can move a little, which is hard on rigid grout and tired sealant. If you look after a building such as Stone St Mary's CofE Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
