How we handle new build mastic in Goose Green
A new build should have a neat, sound bead at every joint. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water reaches anything behind it. We work on plot handovers, skirting & floors and windows & doors, and people most often call us about new-build shower sealant that has already split and gaps between new skirting and floors.
Work in a small place like Goose Green just needs the journey and access planning, and the work itself is the same as on any site.
We stand behind the work with a 12-month guarantee, so you’re covered after we have gone.

People normally contact us after spotting something like this:
- Sealant applied over dusty or wet surfaces
- Gaps opening as the house dries out and settles
- Shower seals failing in the first year or two
- Gaps behind new kitchen upstands
In and around Goose Green, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
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.
Leave it or put it right?
Small cosmetic gaps can wait for the house to settle, but a leaking seal cannot. Not sure whether yours can wait? You can call 0345 464 0079 or email us with a few pictures. Where a wall is exposed, as many are in small places like Goose Green, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
