Common problems we fix in Weston
If plaster or screed was still damp when it was sealed, the bond suffers. On a busy site, joints are not always given time to dry first.
The problems people normally mention when they call are:
- Kitchen sealant that has pulled off the wall
- Smeared, uneven beads picked up at snagging
- Plot mastic for developers ahead of handover
- Cracks appearing as a new home settles
Around Weston, as everywhere, new build mastic is only as good as the preparation behind it.

Honest limits
We’d rather tell you now than do work that will not last, so here’s what sealant can’t put right:
- Damaged fittings that need replacing
- Leaking fittings rather than failed sealant
- A tray or bath that is not properly supported, until it’s fixed
If in doubt, call 0345 464 0079 or email us and we will say what we think.
Surfaces we seal

What new build mastic looks like in Weston
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.
If you’ve bought a new home near Baldock station, the sealant around baths, showers and frames is worth checking in the first year or two.

- The old bead comes out in full, with no layer left behind.
- Surfaces are cleaned of building dust and primed where needed.
- New sealant suited to each joint is applied and tooled neatly.
- Finally, each room is checked and you’re given the cure time.

Advice
Nearby places to Weston
Also in Weston
Surface by surface
Show homes
Show homes need sealant that looks right from day one. Every bead is neat and coloured to suit the room.
Skirting and floors
Wet-area floor joints need a flexible seal. They get a flexible, water-resistant sealant.
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Some sealant jobs are within reach of a careful DIYer, 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.
