Uckfield New Build Mastic
Plot mastic for developers and snagging failed sealant in new homes for homes and businesses in Uckfield and across East Sussex. Fully insured, ARBOMaster approved and guaranteed for a year.
- Leaking shower tray seals in a new home
- Beads laid onto grit and dust from the build
- Gaps between new skirting and floors
Aftercare tips
After the cure time, these simple habits help:
- Follow the cure time we give you
- Avoid running a DIY bead over the old one
- Put sealant faults on your snagging list early
- Avoid scourers and strong chemicals on sealant
Do not stand on the bath edge or the lip of the tray. 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 saves a harder job later.
New build mastic in Uckfield
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. In both, preparation makes the difference since hurried prep is behind a lot of new-build failures. We work on kitchens, plot handovers and bathrooms & en suites, and common reasons people get in touch are cracked sealant around new window and door frames and shower seals failing in the first year or two.
In a town like Uckfield, skirting and floor joints open up as homes settle and floors move with the seasons. Those joints need a flexible sealant, as rigid filler soon cracks out.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Questions from Uckfield
Do you work for landlords with property near Uckfield station?
Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Is there a guarantee on new build mastic in Uckfield?
All our work, in Uckfield and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Do you take out the old sealant first?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Should I try DIY first?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Are you insured?
Yes. Full insurance covers our work.
Will there be a smell?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
Do you do commercial work?
Yes. We work in offices, washrooms, hotels and other commercial premises. We can talk about working times when we quote.
Can you work from my snagging list?
Yes. Snagging lists are a common starting point for us. We agree the sealant items with you before we start.

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Honest limits
It helps to know what we cannot do too:
- Your warranty claim itself, which is between you and the builder
- A tray or bath that isn’t properly supported, until it’s fixed
- Structural cracks in walls or ceilings
