How we handle new build mastic in Clap Hill
Dust is the enemy of new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the new bead bonds properly rather than sitting on a layer of grit. We are often asked to deal with gaps opening as the house dries out and settles and sealant applied over dusty or wet surfaces, on kitchens, bathrooms & en suites and plot handovers.
Somewhere as small as Clap Hill, 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.
A one-year guarantee comes as standard, so you’re not left on your own once the job is done.

Signs you need new build mastic in Clap Hill
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.
Most people get in touch after spotting something like this:
- Joints pulling apart as timber shrinks
- Frame joints opening as the plaster dries
- Sealant that never bonded to the surface
- Plot mastic for developers ahead of handover
For new homes near Ham Street station, it’s worth checking the sealant early, while snags are still fresh.

What we do, step by step
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for most snagging lists, longer for a run of plots, and the area is left clean. For a village or hamlet like Clap Hill, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip 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.
- Each area is checked and left with its cure time.
Getting ready for the visit
- Mention any parking rules near the property
- Mention any tricky access
- For business premises, tell us about site rules or sign-in

New build mastic in Clap Hill: local notes
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

Leave it or put it right?
If you are still in the builder’s snagging or warranty period, ask them to put it right first. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. Where a wall is exposed, as many are in small places like Clap Hill, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first and give you a clear quote before we start.

What the job involves on each surface
Plot handovers
Plot mastic is carried out to the developer’s schedule. Joints are prepared properly before sealing so the sealant lasts.
Skirting and floors
As timber and screed dry, skirting and floors shift. Caulk cracks; a flexible sealant moves with it.

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
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.
Keeping the joints in good condition
After the cure time, these simple habits help:
- Wait for the cure time before using a resealed shower
- Do not seal over failed sealant yourself
- Check bath and shower seals every few months as the house settles
- Photograph failed sealant before it’s redone
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Small faults turn into leaks if left over time.
