About our sand mastic in Minstead
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s a mix of sand and a linseed-oil-based binder and built up by hand. On period homes, it looks right where silicone wouldn’t. If you are dealing with wind and rain getting in round a sash window and window mastic to renew ahead of painting, we can help, whatever the surface.
Outdoor sealant needs dry, clean surfaces, so work on frames around Minstead is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

What happens if it’s left?
Replacing sash windows is a big decision for a period home, and in listed buildings it may need consent. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. Around Minstead, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before we start.

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
