How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Raise failed sealant with the developer while you’re covered
- Check bath and shower seals every few months as the house settles
- Resist patching a failed seal with a tube from the DIY shop
- Photograph failed sealant before it’s redone
Don’t stand on the bath edge or the lip of the tray while the sealant cures. Report any movement in a bath or tray.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Small faults turn into leaks if left.
What we do, step by step
At the end, we look at the finished work together and explain the cure time. The work normally takes a few hours for most snagging lists, longer for a run of plots, depending on how much there is to do. Somewhere like North Weston needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- Failed or untidy sealant is cut out completely.
- Surfaces are cleaned of building dust and primed where needed.
- A sealant chosen for each area goes in and is tooled smooth.
- Finally, each room is checked and you are given the cure time.
How to prepare
- Let us know if you’ve seen damp or leaks
- Let us know about parking restrictions
- Tell us about access, such as stairs, a lift or high-level joints

What happens if it’s left?
Sealant done properly at handover means fewer callbacks. Every return visit for a failed seal takes time and most come down to preparation. In a small place like North Weston, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Doing several joints on one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

When to call us in North Weston
When the heating goes on in the first winter, the house dries fast. Gaps open along skirting, frames and worktops.
People generally contact us after spotting one of these:
- Kitchen sealant that has pulled off the wall
- Cracked caulk along new skirting
- Smeared, uneven beads picked up at snagging
- Plot mastic for developers ahead of handover
Around North Weston, as everywhere, new build mastic is only as good as the preparation behind it.

DIY versus a professional finish
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
