How we handle sand mastic in Bough Beech
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, applied by hand. On period homes, it looks right where silicone wouldn’t. We work on period & listed homes, timber door frames and tenement windows, and common reasons people get in touch are a silicone bead on a sash window that spoils the look and gaps where the frame meets the masonry.
Mastic can only go onto a dry, clean joint, so window work in Bough Beech is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

Should I try it myself first?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

How it works

In total, it generally takes anything from a few hours to a full day, depending on how many windows.

- First, we look at the surrounds with you and agree what needs doing.
- Old, loose mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- We dress the surface so it sits neatly against the masonry.

Sash and case windows
Sash windows are where we do most sand mastic work. We renew the mastic round each box.
Period and listed homes
Materials matter on listed and conservation-area homes. Sand mastic is often the preferred finish.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Sort the mastic before the decorators arrive
- Ask us before painting near the mastic
- Make sure water runs off the sill
- Ask a joiner to look at soft timber first
Don’t run silicone over the new mastic. If anything cracks, get it looked at rather than patching it.
Sound mastic protects the frame. Failed mastic lets water reach the timber, which can lead to rot.
