Wicken Bonhunt Sand Mastic
Problem with your window and door surrounds in Wicken Bonhunt? We remove the old material, prepare the joints and seal them properly, with a 12-month guarantee.
- Mastic round period door frames that has failed
- Window mastic to renew ahead of painting
- Cement or filler used on old window joints that has cracked
Common problems we fix in Wicken Bonhunt
Rain on the window surround works into any crack and pushes it out. Windows facing the weather tend to go first.
Any of these means the joints need attention:
- Mastic worn away on windows facing the weather
- Gaps between timber frames and stone or brick
- A silicone bead on a sash window that spoils the look
- Window mastic to renew ahead of painting
Managing a site like Joyce Frankland Academy? Then larger buildings have plenty of frames, and the mastic around each one ages.

How we handle sand mastic in Wicken Bonhunt
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 work on timber door frames, sash and case windows and brick reveals, and people most often call us about window mastic to renew ahead of painting and failed mastic on an exposed elevation.
Homes in small places like Wicken Bonhunt often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

What the job involves on each surface
Brick reveals
We rake out the old mastic and pack deep voids before the new mastic goes in.
Timber door frames
Doors face weather and wear, so their mastic can fail sooner. We rake it out and renew it.
How it works
When we arrive, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before any work begins. Most jobs take anything from a few hours to a full day, depending on how many windows. Somewhere as small as Wicken Bonhunt, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check the window surrounds and agree which joints need renewing.
- We rake out the old mastic and clean the joint.
- Large voids are packed out first, so the mastic is not too thick.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Mention any sign-in or site rules at work premises
- Tell us about access, such as stairs, a lift or high-level joints

Sand mastic in Wicken Bonhunt: local notes
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Audley End House (about 3.7 miles north-east) nearby, there’s older building stock in the area around Wicken Bonhunt as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
For an older house near a landmark such as Church of St Margaret, the joint between an old wall and a newer frame is usually the first place rain gets in. If you let a flat or house near Newport (Essex) station, any sash windows need sound mastic to keep draughts and rain out.

Why act early in Wicken Bonhunt
If you are redecorating, renew the mastic first. Painting over failed mastic does not seal it and traditional guidance is to leave the new mastic unpainted. Older cottages and farmhouses around Wicken Bonhunt 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 price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.

Questions from Wicken Bonhunt
I let a flat near Newport (Essex) station. Can you help?
Yes, rental work is part of what we do. You can call 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before any work starts.
Is Wicken Bonhunt in your area for sand mastic?
Yes. We work across London and the South East, and Wicken Bonhunt is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear price.
Will you leave a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Should I try DIY first?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Will there be a smell?
There can be a smell while the sealant cures. Ventilation helps.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Does someone need to be in?
If the work is inside, we need someone to let us in. Once we have agreed the job, you don’t need to watch us work.
Is it possible to take out silicone and use sand mastic instead?
Generally, yes. With the silicone removed and the joint cleaned, sand mastic is applied by hand.
How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Inspect the joints round the windows every year or so
- Ask the planning authority about consent for listed or conservation-area homes
- Take care around the mastic when scraping paint
- Avoid patching sand mastic with silicone
Keep paint scrapers and sanders off the mastic when redecorating. It can be damaged by heavy scraping.
Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.
