Advice
What we’re called out for in Milton-next-Gravesend
If plaster or screed was still damp when it was sealed, the bond suffers. Site programmes don’t always leave time for joints to dry first.
Any of these means the joints need attention:
- Kitchen sealant that has pulled off the wall
- Cracked sealant around new window and door frames
- Plot mastic for developers ahead of handover
- New-build shower sealant that has already split
If you’ve bought a new home near Gravesend station, the sealant around baths, showers and frames is worth checking in the first year or two.
Before you book anyone
- When the joint can take water or movement
- Whether all the old sealant comes out first
- Whether you can choose the colour
- Who turns up on the day

Milton-next-Gravesend: your questions answered
Do you work for landlords with property near Gravesend station?
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 work begins.
Do you cover smaller places like Milton-next-Gravesend?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
What information do you need?
The location, the problem and the rough size of the job. If you can, email a few photos.
Is it worth trying it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
Is it normal for sealant to crack in a new home?
Cracking in the first couple of years is common. Rushed application on dusty surfaces makes it worse.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Will you just run a new bead over the existing one?
No. New silicone will not bond to old silicone, so sealing over the top fails quickly. We cut the old bead out completely.
Can you do plot mastic on a new development?
Yes. Plot mastic and second-fix sealing for developers is part of our work. Send the schedule and any specification and we will give you a quote.
What sealant work can’t fix
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Settlement cracks that need a surveyor
- Disputes or warranty claims with your builder
- Leaking fittings rather than failed sealant
If you’re not sure, just call 0345 464 0079 or email us and we will give you a straight answer before booking.

Why deal with it now?
The builder is generally the first port of call while the snagging or warranty period runs. If it keeps failing or is not dealt with, we can reseal it properly. In an older home around Milton-next-Gravesend, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
Why choose Mr Mastic in Milton-next-Gravesend

Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Get a leaking seal dealt with right away
- Follow the cure time we give you
- Ventilate bathrooms well, especially in the first year
- Report sealant problems to your builder during the snagging period
Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents.
If a shower tray or bath seal splits in the first year, look for movement. Have it resealed, and the tray or bath checked, before it gets worse.
