Sand mastic in Beenham Stocks, done properly
Sand mastic doesn’t last for ever and gaps open up round the frame. We rake it out and renew it so the surround looks right again. We work on tenement windows, stone surrounds and timber door frames, and the jobs we see most are open joints round the window box and tired mastic found when preparing windows for paint.
Homes in small places like Beenham Stocks often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
There’s a 12-month guarantee on every job.

Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Go gently near the mastic when preparing windows
- Renew mastic before redecorating the windows
- Ask the planning authority about consent for listed or conservation-area homes
- Make sure water runs off the sill
Leave the new mastic unpainted, which is the traditional advice. Ask us before any decorating around it.
Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall so early renewal protects both.
DIY versus a professional finish
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
If you are set on DIY, put the effort into 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.
What the job involves on each surface
Brick reveals
An open joint at a brick reveal lets weather in. New mastic seals the gap.
Timber door frames
A neat sand mastic joint round a front door suits a period home.
For landlords and businesses
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
The process
You don’t need to clear the whole room or building before we come, only the area right around the joints. Everything nearby is protected, and the work takes a few hours for a single window, longer for several for a typical job. Somewhere like Beenham Stocks needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic isn’t too thick.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- Mention any leaks or damp you’ve noticed
- Keep children and pets away from the work area

Related advice
Why it’s worth doing now in Beenham Stocks
Draughts round a sash window are not always the sashes. Open mastic joints round the box can let air in and new mastic seals them. Older cottages and farmhouses around Beenham Stocks can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

Do you need sand mastic in Beenham Stocks?
Most of it is simply age. Even well-laid mastic needs renewing in time, depending on exposure and upkeep.
The problems people generally mention when they call include:
- Crumbling sand mastic round a window
- A silicone bead on a sash window that spoils the look
- Gaps where the frame meets the masonry
- Gaps round a timber door in stone or brick
If you look after a building such as Beenham Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
