New build mastic in East Chiltington
New homes move as they dry out. Timber shrinks, plaster dries and baths and trays bed down, and sealant applied in a hurry at handover can split. We work on kitchens, bathrooms & en suites and show homes, and common reasons people get in touch are kitchen sealant that has pulled off the wall and frame joints opening as the plaster dries.
In a village or hamlet like East Chiltington, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
All our work comes with our one-year guarantee, wherever you are in East Sussex.

What we do, step by step
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours in a single home. Somewhere like East Chiltington needs a little journey planning: 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.
- Each joint is checked for movement before we start.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
How to prepare
- Keep children and pets away from the work area
- Tell us about access, such as stairs, a lift or high-level joints
- Clear the area around the work

Why it’s worth doing now in East Chiltington
A tube of sealant from the DIY shop won’t fix the cause: dust, no primer and old sealant left in the joint. Cutting out, cleaning and priming are what make the difference. Older cottages and farmhouses around East Chiltington can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you are not sure whether it needs doing, phone 0345 464 0079 or send us an email and we will give you an honest view and a quote.
What you get with us
- White, clear, grey or another colour, product permitting
- A 12-month guarantee on all work
- Experience in homes, commercial sites and hotels
- Tidy, careful work
Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
A careful DIYer can reseal a simple joint, 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 East Chiltington?
Once people move in, baths and trays take weight and bed down. A bath sealed empty drops slightly when filled, straining the joint.
Look out for any of the following:
- Shower seals failing in the first year or two
- Frame joints opening as the plaster dries
- Gaps opening as the house dries out and settles
- Gaps behind new kitchen upstands
In and around East Chiltington, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Questions to ask before booking
- How long the guarantee is
- How much experience the applicator has
- Whether all the old sealant comes out first
- Whether they’re fully insured
How to look after the new joints
Good habits help new joints last longer. A few tips:
- Wipe joints with warm soapy water
- Keep pictures and emails about snagging items
- Get a leaking seal dealt with right away
- Report sealant problems to your builder during the snagging period
Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents as they wear the bead.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in keeps the job straightforward.
What sealant work can’t fix
Before booking, it’s worth knowing the limits:
- Damaged fittings that need replacing
- Baths and trays that move too much for sealant to cope with
- Leaks from pipes, valves or wastes, which need a plumber
