Keeping the joints in good condition
After the cure time, these simple habits help:
- Get a leaking seal dealt with straight away
- Look at the sealant regularly in the first couple of years
- Resist patching a failed seal with a tube from the DIY shop
- Open a window or run the fan after bathing
Ventilation matters in a new home, which is still drying out. Run the fan or open a window after bathing.

If in doubt, call 0345 464 0079 or email us and we’ll say what we think before you book.

Questions from Sulhamstead Bannister Upper End
Is Sulhamstead Bannister Upper End in your area for new build mastic?
Yes. We work across London and the South East, and Sulhamstead Bannister Upper End is part of that. You can phone 0345 464 0079 or drop us an email and let us know what needs doing.
Can you help a landlord with a rental near Theale station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or send us an email and tell us about the property, and we will send you a clear quote.
Will it make a mess?
Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we’re done.
Can you match the sealant colour to my new kitchen or bathroom?
Most bathroom joints are white or clear, but other colours are available. We match the colour to the finish and agree it with you.
Can new sealant go on top of the old bead?
No. New silicone won’t bond to old silicone, so sealing over the top fails quickly. We cut the old bead out completely.
Do you guarantee your work?
Yes, always. Each job is guaranteed for twelve months.
Is there any odour?
Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.
Do you remove the old sealant?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Should I try it myself first?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
