How we handle new build mastic in Bishopsbourne
New homes move as they dry out. Timber dries and shrinks, and baths and trays settle, and sealant applied in a hurry at handover can split. Common call-outs are for kitchen sealant that has pulled off the wall and cracked sealant around new window and door frames, across bathrooms & en suites, show homes and skirting & floors.
Work in a small place like Bishopsbourne just needs the journey and access planning, and the work itself is the same as on any site.
There’s a 12-month guarantee on every job, large or small.

What sealant work can’t fix
It helps to know what we can’t do:
- Cracking that points to a structural problem
- Leaks from pipes, valves or wastes, which need a plumber
- A tray or bath that isn’t properly supported, until it’s fixed
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly.
What we seal
- Skirting & floors
- Show homes
- Plot handovers
- Bathrooms & en suites
- Windows & doors
- Kitchens
Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Check bath and shower seals every few months as the house settles
- Report sealant problems to your builder during the snagging period
- Keep photos and emails about snagging items
- Act quickly if a seal starts to leak
Ventilation matters in a new home, which is still drying out. Use the extractor fan or open a window after showers.
Early snagging is easier snagging. Small faults turn into leaks if left.
Signs you need new build mastic in Bishopsbourne
Fresh sealant can be knocked or cut by trades finishing off. A bead disturbed before it has cured may never seal properly.

- Sealant that never bonded to the surface
- Untidy sealant flagged on a snagging list
- Leaking shower tray seals in a new home
- Sealant work across a run of new homes
If you’ve bought a new home near Bekesbourne station, the sealant around baths, showers and frames is worth checking in the first year or two.

Surface by surface
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. We reseal once the old bead is fully out and baths are filled before sealing.
Show homes
We seal show-home bathrooms, kitchens and frames ready for viewings. We’ll plan around viewing times.
Can I do it myself?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Some sealant jobs are within reach of a careful DIYer, 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.
How the visit works
When we arrive, we start by going over the job with you. Surfaces next to the work are protected before any work begins. Most jobs take anything from a few hours to several days, depending on the number of plots. Somewhere like Bishopsbourne needs a little journey planning: 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.
- We go through the snagging list or plot schedule and agree the joints to do.
- We cut out every bit of the failed or messy sealant.
- 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
- Keep children and pets away from the work area
- For business premises, tell us about site rules or sign-in
- Clear the area around the work

Why deal with it now?
Small cosmetic gaps can wait for the house to settle, but a leaking seal can’t. Not sure whether yours can wait? You can phone 0345 464 0079 or drop us an email with a few photos. Around Bishopsbourne, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
A failed joint rarely gets cheaper to fix by waiting. If you’re unsure, call 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.
