New homes and floors in Pett
Pett is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so any gaps are best picked up early. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Around Pett, as everywhere, new build mastic is only as good as the preparation behind it.

About our new build mastic in Pett
Some owners wait for the first year’s movement before having joints redone. That makes sense for small gaps that are just cosmetic, but a seal that is letting water through needs doing now. We work on plot handovers, windows & doors and kitchens, and people most often call us about smeared, uneven beads picked up at snagging and worktop and upstand sealant coming away.
Work in a small place like Pett just needs the journey and access planning, and the work itself is the same as on any site.
Each job carries a 12-month guarantee, whatever its size.

How the visit works
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. It generally takes a few hours in a single home. For a village or hamlet like Pett, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We go through the snagging list or plot schedule and agree the joints to do.
- We cut out every bit of the failed or messy sealant.
- Each joint is cleaned of dust and grit, then primed if required.
- New sealant suited to each joint is applied and tooled neatly.
- We check every joint and tell you how long each needs to cure.
Before we arrive
- Let us know about parking restrictions
- Clear items away from the joints we are working on
- For indoor joints, keep the area dry beforehand if you can

Why it’s worth doing now in Pett
A hairline gap at a skirting can wait, but water getting through cannot. If you are unsure which you have, phone 0345 464 0079 or drop us an email with photos. Older cottages and farmhouses around Pett can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
The cost depends on the size of the job, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts.

For landlords and businesses

DIY versus a professional finish
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Signs you need new build mastic in Pett
A new house holds a lot of water from the build, and it dries out over the first couple of years. Drying timber shrinks and pulls joints apart, and sealant that can’t keep up splits.
If you can see any of these, it’s time to have the joints looked at:
- Worktop and upstand sealant coming away
- Shower seals failing in the first year or two
- Untidy sealant flagged on a snagging list
- Beads laid onto grit and dust from the build
If you’ve bought a new home near Three Oaks station, the sealant around baths, showers and frames is worth checking in the first year or two.
What your quote should include
- What guarantee comes with the work
- When the joint can take water or movement
- Which colour the sealant will be
- What preparation is included
What affects the quote in Pett
We quote each job individually. This is what makes a difference:
- Any mould that needs treating
- When we can work, for business premises
- The size of the job
- Whether old sealant or filler has to be cut out
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.
Asking for a quote
You don’t need to know the technical terms. Just tell us:
- Where the property is
- The type of property
- Roughly how big the job is
- What’s wrong with the joints now
Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we’ll explain what’s involved before giving you a price.

Bathrooms, kitchens and frames in show homes are sealed or resealed to a neat finish. We will plan around viewing times.
