About our sand mastic in Woodnesborough
Burnt sand mastic is a traditional material blends with stone and brick surrounds. It suits period and listed homes, where modern sealant can look out of place. We work on tenement windows, brick reveals and sash and case windows, and common reasons people get in touch are cracked mastic round a front door frame and gaps between timber frames and stone or brick.
Outdoor sealant needs dry, clean surfaces, so work on frames around Woodnesborough is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
The work is covered for a year after we finish. If anything isn’t right with it, call 0345 464 0079 or send us an email.

Sash and case windows
On a sash window, the mastic joint shows on the outside so we finish it carefully.
Timber door frames
Doors face weather and wear, so their mastic can fail sooner. It’s renewed by hand.

What sand mastic looks like in Woodnesborough
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Goodnestone Park (about 3.8 miles west) nearby, there’s older building stock in the area around Woodnesborough as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Schools such as Sandwich Technology School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around Church of St Mary the Virgin, the joint between an old wall and a newer frame is normally the first place rain gets in.

Questions to ask before booking
- What happens if they find a problem under the old sealant
- Are they insured?
- Which sealant they’ll use, and why
- How the joint is cleaned and prepared
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Why act early in Woodnesborough
Draughts round a sash window are not always the sashes. Gaps between the frame and the wall can be just as bad, and renewing the mastic closes them. Older cottages and farmhouses around Woodnesborough can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Ask a joiner to look at soft timber first
- Go gently near the mastic when preparing windows
- Leave the new mastic unpainted
- Look over the window mastic once a year
Leave the new mastic unpainted, as traditional guidance advises. If you’re redecorating, ask us first.
Sound mastic protects the frame. Failed mastic lets water reach the timber, which can lead to rot.
