New build mastic in Shortgate
In a new home, every joint should have a clean, even bead. Smeared, patchy or cracked sealant is worth sorting early, before water reaches anything behind it. We work on plot handovers, windows & doors and bathrooms & en suites, and the jobs we see most are sealant that never bonded to the surface and gaps between new skirting and floors.
Around Shortgate, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

What we can’t put right
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Broken tiles or a split tray
- Plumbing faults behind the sealant
- Your warranty claim itself, which is between you and the builder

Why deal with it now?
A quick bead over the top of the old sealant can look fine at first, but it won’t bond to the old layer. A lasting seal starts with removing the old one completely. Where a wall is exposed, as many are in small places like Shortgate, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
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 we need extra access for height. Your quote takes all of that into account.

Related advice
Can I do it myself?
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.
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.

Do you need new build mastic in Shortgate?

- Untidy sealant flagged on a snagging list
- Plot mastic for developers ahead of handover
- Frame joints opening as the plaster dries
- New-build shower sealant that has already split
For new homes near Uckfield station, it’s worth checking the sealant early, while snags are still fresh.

Questions from Shortgate
Will you come out to Shortgate?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Yes, we work for landlords and agents. 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 any work starts.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all.
Can you quote for more than one area?
Yes. Several rooms, windows or areas can go on one quote.
What does new build mastic cost?
Size, access and the old material all affect the cost. Ask us for a quote and we will talk you through it.
What sealant do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We will tell you what we are using and why.
Will you just run a new bead over the existing one?
No. New silicone will not bond to old silicone, so it soon lifts and traps water. We cut the old bead out completely.
Why does sealant fail so quickly in new builds?
A new house dries and settles for a year or two, and sealant is often applied quickly onto dusty surfaces. Either can make it fail early.
How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Resist patching a failed seal with a tube from the DIY shop
- Watch for new gaps as the house dries out
- Follow the cure time we give you
- Clean sealant with mild detergent, not abrasives
Avoid standing on the rim of the bath or the edge of the tray while the sealant cures. If a bath or tray moves when you stand in it, get it looked at.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in keeps the job straightforward.
