Sand mastic in Little Braxted, done properly
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s a mix of sand and a linseed-oil-based binder and built up by hand. On older homes, it suits the building far better than silicone. We are often asked to deal with crumbling sand mastic round a window and mastic round period door frames that has failed, on period & listed homes, stone surrounds and sash and case windows.
Mastic can only go onto a dry, clean joint, so window work in Little Braxted is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

What we do, step by step
There is not much for you to do on the day. Point us to the joints and we’ll get on with it. The work itself takes anything from a few hours to a full day, depending on how many windows. In a small place like Little Braxted, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each surround and agreeing the joints to renew.
- Old, loose mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The finish is dressed so it sits neatly against the stone or brick.

Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

Signs you need sand mastic in Little Braxted
Age is the main cause. Sand mastic is a maintenance item like any pointing, depending on exposure and upkeep.
Look out for these signs:
- Gaps round a timber door in stone or brick
- Mastic dropping out of the joint
- Tired mastic found when preparing windows for paint
- A silicone bead on a sash window that spoils the look
For an older house near a landmark such as Church of St Nicholas, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

How to look after the new joints
Good habits help new joints last longer. A few tips:
- Inspect the joints round the windows every year or so
- Check with your local planning authority if your home is listed
- Take care around the mastic when scraping paint
- Plan mastic work ahead of painting
Make sure water drains away from the window surround. Water sitting against the mastic shortens its life.
Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.
