New build mastic in Green Hailey, done properly
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. If you’re still within the builder’s snagging or warranty period, tell them first, and if it is not put right, get in touch with us. We work on kitchens, skirting & floors and plot handovers, and common reasons people get in touch are gaps behind new kitchen upstands and new-build shower sealant that has already split.
Somewhere as small as Green Hailey, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
All our work is covered by our 12-month guarantee, wherever you are in Buckinghamshire.

The cost reflects the work involved, not guesswork. That is why we ask a few questions first and give you a clear price before work begins.

DIY sealant or a professional job?
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Why it’s worth doing now in Green Hailey
For developers, getting the sealant right first time saves return visits. Every return visit for a failed seal takes time. Where a wall is exposed, as many are in small places like Green Hailey, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
The cost depends on the size of the job, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.
