New build mastic in Fairlight
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. In both, preparation makes the difference. We work on windows & doors, plot handovers and bathrooms & en suites, and common reasons people get in touch are plot mastic for developers ahead of handover and gaps opening as the house dries out and settles.
Somewhere as small as Fairlight, new homes tend to be conversions, self-builds or a few houses rather than an estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
All our work is covered by a 12-month guarantee, wherever you are in East Sussex.

Different surfaces, different methods
Bathrooms and en suites
En suite showers are a common source of leaks into the room below. A proper reseal keeps water in the tray.
Kitchens
As a new house dries, worktops and walls shift a little, opening gaps behind the upstand. A fresh flexible bead closes them.
How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Keep water off fresh sealant until it has cured
- Resist patching a failed seal with a tube from the DIY shop
- Clean sealant with mild detergent, not abrasives
- Ventilate bathrooms well, especially in the first year
Keep an eye on the joints over the first couple of years. Hairline gaps can open as timber and plaster dry.
Report failed sealant to the builder while you are in the snagging period. After that, putting it right may fall to you.
New build mastic in Fairlight: local notes
Fairlight is within about 1 mile of 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. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In and around Fairlight, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint. 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.

Fairlight: your questions answered
Do you work for landlords with property near Three Oaks station?
Yes, we work for landlords and letting agents. Just call 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear price.
Is Fairlight within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Where do you work from?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Is it worth trying it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
Do you have insurance?
Yes. We are fully insured, and we can confirm the details when we quote.
Should I wait before resealing?
That depends on the joint. A leaking shower or bath seal should be redone right away, but cosmetic gaps can wait for movement to slow.
Who should fix failed sealant in a new build?
Report it to the builder first while you’re covered. Once that is done, or if they will not put it right, we’ll cut it out and reseal it.
Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
How it works
The work is kept neat and contained to the area we’re working on, so you can get on with your day. The job generally takes a few hours for most snagging lists, longer for a run of plots, and we explain the cure time before we leave. For a village or hamlet like Fairlight, 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.
- First we work through your snagging list or plot schedule with you.
- The old bead comes out in full, with no layer left behind.
- Each joint is cleaned of dust and grit, then primed if required.
- A sealant chosen for each area goes in and is tooled smooth.
- Finally, each room is checked and you are given the cure time.
Preparing for the visit
- Clear the area around the work
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us about any water getting in

Advice
Why it’s worth doing now in Fairlight
Small cosmetic gaps can wait for the house to settle, but water getting through can’t. If you are unsure which you have, phone 0345 464 0079 or drop us an email with photos and we’ll tell you. Around Fairlight, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
