Why it’s worth doing now in Goodworth Clatford
Gaps round a sash window let in rain and draughts. Left, water can reach the timber and the wall, so dealing with it now protects both. Older cottages and farmhouses around Goodworth Clatford can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Doing several joints on one visit is usually more efficient than separate visits, so tell us about everything that needs sealing. We will give you a clear quote for the lot.

How we handle sand mastic in Goodworth Clatford
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s made from sand and a linseed-oil-based binder, applied by hand. On older homes, it suits the building far better than silicone. We work on tenement windows, sash and case windows and timber door frames, and people most often call us about gaps between timber frames and stone or brick and mastic dropping out of the joint.
Outdoor sealant needs dry, clean surfaces, so work on frames around Goodworth Clatford is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
All of our work is guaranteed for twelve months, in Goodworth Clatford and everywhere else we cover.

Aftercare tips
To keep the joints looking good and working properly:
- Ask the planning authority about consent for listed or conservation-area homes
- Renew mastic before redecorating the windows
- Ask us before painting near the mastic
- Avoid heavy scraping on the mastic joint
Do not run silicone over the new mastic. If you see a crack, ask us to take a look rather than patching it.
Sound mastic protects the frame. Once it fails, water can sit against the timber and timber that stays wet can rot.
What happens on the day
Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes a few hours per window, depending on the condition of the joints, depending on the size of the job. Somewhere like Goodworth Clatford needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- 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.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The mastic is finished to sit tidily against the stone or brick.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Keep pets and children clear of the area while we work
