About our new build mastic in East Hoathly
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’s letting water through needs doing now. We work on show homes, bathrooms & en suites and windows & doors, and common reasons people get in touch are skirting joints opening in the first winter and sealant that never bonded to the surface.
In a village or hamlet like East Hoathly, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
Big or small, you get the same one-year guarantee.

Why it’s worth doing now in East Hoathly
A tube of sealant from the DIY shop will not fix the cause: grit, unprimed surfaces and old layers underneath. Cutting out, cleaning and priming are what make the difference. Older cottages and farmhouses around East Hoathly can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first.
Why us?
- Trusted Arbo and Everbuild sealants
- ARBOMaster approved applicator
- We never seal over old sealant

Signs you need new build mastic in East Hoathly
A new house holds a lot of water from the build, which takes a year or two to dry out. As it does, timber shrinks and joints open, and sealant that cannot keep up splits.
Keep an eye out for any of the following:
- Shower seals failing in the first year or two
- Joints pulling apart as timber shrinks
- Plot mastic for developers ahead of handover
- Skirting joints opening in the first winter
Around East Hoathly, as everywhere, new build mastic is only as good as the preparation behind it.

How to look after the new joints
To keep the joints looking good and working properly:
- Keep water off fresh sealant until it has cured
- Raise failed sealant with the developer while you are covered
- Record problems with dated pictures
- Open a window or run the fan after bathing
Wipe the sealant with warm soapy water. Keep scourers and harsh chemicals off it.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black saves a harder job later.

Windows and doors
A draught at a new window can be a missed or failed joint. We look at the joints and reseal where needed.
