Why it’s worth doing now in Charlton
For developers, getting the sealant right first time saves return visits. Every return visit for a failed seal takes time, and they’re avoidable with good preparation. Around Charlton, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
The cost depends on the size of the job, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts, so you know where you stand.

About our new build mastic in Charlton
Developers send us the plot schedule and we work through it. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover using the right product for each joint. We work on skirting & floors, bathrooms & en suites and show homes, and the jobs we see most are gaps opening as the house dries out and settles and sealant work across a run of new homes.
Older homes in small places like Charlton often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

What else we do in Charlton
Can I do it myself?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
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.
What sealant work can’t fix
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Leaks from pipes, valves or wastes, which need a plumber
- Damaged fittings that need replacing
- Baths and trays that move too much for sealant to cope with
If in doubt, call 0345 464 0079 or send us an email and we will say what we think.

Joints and finishes in Charlton homes
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For new homes near Andover station, it’s worth checking the sealant early, while snags are still fresh.

Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Raise failed sealant with the developer while you’re covered
- Get a leaking seal dealt with straight away
- Look at the sealant regularly in the first couple of years
- Open a window or run the fan after bathing
Keep the bathroom ventilated, especially in the first year. Run the fan or open a window after bathing to help keep mould away.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black saves a harder job later.

Do you need new build mastic in Charlton?
Once people move in, baths and trays take weight and bed down. A bath sealed empty drops slightly when filled, straining the joint and the sealant may split.
If you can see any of these, it’s time to have the joints looked at:
- Untidy sealant flagged on a snagging list
- Shower seals failing in the first year or two
- Kitchen sealant that has pulled off the wall
- Cracks appearing as a new home settles
Around Charlton, as everywhere, new build mastic is only as good as the preparation behind it.
