New build mastic in Chailey, done properly
We never seal over a failed new-build bead. New silicone will not bond to old silicone, so the joint is cut out, cleaned, dried and resealed. We are often asked to deal with sealant that never bonded to the surface and gaps opening as the house dries out and settles, on kitchens, bathrooms & en suites and windows & doors.
In a village or hamlet like Chailey, 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 is covered by a one-year guarantee, wherever you are in East Sussex.

For landlords and businesses
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
We work for letting agents and landlords as well as householders. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
DIY versus a professional finish
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
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.
What new build mastic looks like in Chailey
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For new homes near Plumpton station, it’s worth checking the sealant early, while snags are still fresh.

Common questions in Chailey
Do you work for landlords with property near Plumpton station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear quote.
Do you cover smaller places like Chailey?
Yes. Chailey is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is it normal for sealant to crack in a new home?
New homes dry out and move in their first couple of years, and sealant is often applied quickly onto dusty surfaces. Either can make it fail early.
When is the best time to reseal in a new build?
Where water is getting through, don’t wait. Hairline cosmetic gaps can wait until the house has settled.
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.
Can you work from my snagging list?
Yes. Send the list and a few photos of the sealant items and we will give you a quote. We’ll tell you if anything on it is not a sealant job.
Can you reseal over the builder’s sealant?
No. Sealing over old sealant looks fine for a few weeks, then lifts. All the old sealant comes out before work begins.
Where do you work from?
We are a Crawley-based firm. We work across South East England, London and Scotland.
The process
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for most snagging lists, longer for a run of plots, and the area is left clean. Somewhere as small as Chailey, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Tell us if parking is tricky
- Let us know about earlier repairs to the joints
Get a quote
Getting a quote is simple: let us know the job and the location, and roughly how big it is. A few pictures by email make the job easier to understand, and we’ll take it from there.
Advice
How to look after the new joints
Aftercare is simple:
- Wipe joints with warm soapy water
- Ventilate bathrooms well, especially in the first year
- Report sealant problems to your builder during the snagging period
- Keep water off fresh sealant until it has cured
Keep an eye on the joints over the first couple of years. Hairline gaps can open as timber and plaster dry.
If a shower tray or bath seal splits in the first year, look for movement. Have it resealed, and the tray or bath checked, before it gets worse.

Common problems we fix in Chailey
A new house holds a lot of water from the build, which takes a year or two to dry out. Drying timber shrinks and pulls joints apart.
Most people get in touch when they notice something like this:
- Sealant that never bonded to the surface
- Kitchen sealant that has pulled off the wall
- Frame joints opening as the plaster dries
- Joints pulling apart as timber shrinks
Around Chailey, as everywhere, new build mastic is only as good as the preparation behind it.

Leave it or put it right?
Resealing everything on a snagging list in one visit is usually simpler than chasing joints one at a time. It’s one visit, one quote and one set of cure times. Around Chailey, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.
