How we handle new build mastic in Broad Oak
A new build should have a neat, sound bead at every joint. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water gets into the floor or walls. We work on skirting & floors, bathrooms & en suites and kitchens, and the jobs we see most are second-fix sealing on new plots and gaps behind new kitchen upstands.
For a small place like Broad Oak, the journey and access are planned in advance, and the work itself is the same as on any site.
You get a one-year guarantee, the same in Broad Oak as everywhere else we work.

Your questions about new build mastic in Broad Oak
Can you do new build mastic in Broad Oak?
Yes. Our work covers London and the South East, and Broad Oak is part of that. You can call 0345 464 0079 or send us an email and let us know what needs doing, and we’ll give you a clear price.

Yes, rental work is part of what we do. You can ring 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before any work starts.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures.
How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint before we leave.
Where are you based?
Mr Mastic is based in Crawley. We cover Broad Oak and the rest of East Sussex.
My new home is still under warranty. Should I contact you?
Report it to the builder first while you are covered. If it isn’t resolved, we’ll cut it out and reseal it.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Will it make a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
What we cannot put right
We’ll always be straight with you, so here’s what new sealant will not do:
- Cracking that points to a structural problem
- Your warranty claim itself, which is between you and the builder
- Broken tiles or a split tray
If you are not sure, just call 0345 464 0079 or email us and we will give you a straight answer before booking.

- We clean out the dust and grit left from the build.

When to call us in Broad Oak
New homes are full of moisture from plaster, screed and concrete, 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.
Any of these means the joints need attention:
- Kitchen sealant that has pulled off the wall
- Plot mastic for developers ahead of handover
- Cracks appearing as a new home settles
- Beads laid onto grit and dust from the build
Around Broad Oak, as everywhere, new build mastic is only as good as the preparation behind it.

Aftercare tips
So the new joints stay in good condition:
- Resist patching a failed seal with a tube from the DIY shop
- Keep water off fresh sealant until it has cured
- Put sealant faults on your snagging list early
- Check bath and shower seals every few months as the house settles
Leave the sealant for the cure time we give you before showering or bathing. Silicone is generally left for about a day before water reaches them.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant.
How the job changes by surface
Skirting and floors
Gaps under skirting are one of the most common new-build snags. A flexible sealant closes it without cracking like caulk.
Bathrooms and en suites
En suite seals are easy to miss on a snagging list until they leak. A proper reseal keeps water in the tray.
What new build mastic looks like in Broad Oak
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For new homes near Stonegate station, it’s worth checking the sealant early, while snags are still fresh.
