Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Keep water off fresh sealant until it has cured
- Resist patching a failed seal with a tube from the DIY shop
- Don’t wait for the house to settle if water is getting through
- Open a window or run the fan after bathing
Follow the cure time we give you before the area gets wet. Silicone is usually left for about a day to cure enough for use.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in keeps the job straightforward.
How the job changes by surface
Skirting and floors
Floors and skirting move as the house dries and the heating runs. We use a flexible product rather than caulk painted or coloured to suit.
Kitchens
Worktop, upstand and sink joints in new kitchens often get a hurried bead. We remove it and reseal with a kitchen-suitable sealant.

Are you ARBOMaster approved?

How long should I leave it?

Where is Mr Mastic based?
We are based in Crawley, and we cover South East England, London and all of Scotland.
Is it worth resealing while the house is still settling?
Any seal that’s leaking should be redone straight away. Cosmetic gaps can wait until the first year or two of movement has passed.
Do you take out the old sealant first?
Yes, always, and completely. New silicone does not stick to old silicone, so the joint is cleaned back first.
Can you reseal over the builder’s sealant?
No. Over-sealing traps mould and water and soon fails. All the old sealant comes out before work begins.
What happens if it’s left?
A tube of sealant from the DIY shop won’t fix the cause: grit, unprimed surfaces and old layers underneath. Cutting out, cleaning and priming are what make the difference. Around West Hoathly, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
