New build mastic in Cubitt Town
Dust is the enemy of new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the new bead bonds properly. We work on windows & doors, kitchens and skirting & floors, and the jobs we see most are worktop and upstand sealant coming away and shower seals failing in the first year or two.
Across London, commercial floors have movement joints that break down under heavy foot traffic, while new homes need a neat, sound finish around frames, baths and kitchens before handover, in Cubitt Town and beyond.
The work is covered for a year after we finish. If anything is not right with it, phone 0345 464 0079 or email us.

Common questions in Cubitt Town
Can parking be tricky for a visit in Cubitt Town?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
Do you work for landlords with property near Canary Wharf station?
Yes. We work for landlords and letting agents as well as homeowners. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll send you a clear quote.
Do you cover Cubitt Town?
Yes. We cover Cubitt Town, as part of our work across South East England, London and Scotland. To book, call 0345 464 0079 or send us an email.
Can you do plot mastic on a new development?

Where is Mr Mastic based?
We’re based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
How long does new build mastic take?
Most jobs take a few hours in a single home, including the preparation. Your quote will say how long we expect yours to take.
Do you remove the old sealant?
Yes, always, and completely. New sealant will not bond properly to old, so the joint is cleaned back first.
Do you work through snagging lists?
Yes. Send the list and a few pictures of the sealant items. We will flag anything that needs another trade.
Leave it or put it right?
A hairline gap at a skirting can wait, but a leaking seal cannot. Not sure whether yours can wait? You can phone 0345 464 0079 or email us with a few photos and we will give you a straight answer. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Cubitt Town, the repair is bigger than the sealant job would have been.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

Advice
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Look at the sealant regularly in the first couple of years
- Raise failed sealant with the developer while you are covered
- Resist patching a failed seal with a tube from the DIY shop
- Use the extractor fan every time you shower
Keep the bathroom ventilated, especially in the first year. Use the extractor fan or open a window after showers.
Early snagging is easier snagging. Left alone, a small crack can become a leak in a busy bathroom.
Should I try it myself first?
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Do you need new build mastic in Cubitt Town?
A new house holds a lot of water from the build, and it dries out over the first couple of years. As it does, timber shrinks and joints open and the sealant has to cope with the movement.
The most common problems we see are:
- Cracks appearing as a new home settles
- Plot mastic for developers ahead of handover
- Shower seals failing in the first year or two
- Skirting joints opening in the first winter
If you’ve bought a new home near Canary Wharf station, the sealant around baths, showers and frames is worth checking in the first year or two.
