About our sand mastic in Ashwell End
Sand mastic doesn’t last for ever, leaving gaps round the window. Renewing it closes the gap so the surround looks right again. We are often asked to deal with old cement repairs round a window that have failed and open joints round the window box, on stone surrounds, brick reveals and sash and case windows.
Mastic can only go onto a dry, clean joint, so window work in Ashwell End is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
All of our work is guaranteed for twelve months, in Ashwell End and everywhere else we cover.

Frames and glazing around Ashwell End
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Hinxworth Place (about 0.9 miles west) are a reminder that the area around Ashwell End has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Schools such as Ashwell Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. If you let a flat or house near Ashwell & Morden station, any sash windows need sound mastic to keep draughts and rain out.

Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
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 Ashwell End
Over the years, sand mastic weathers. It hardens, cracks and starts to come away from the frame or the masonry.
People generally contact us when they notice something like this:
- Failed mastic on an exposed elevation
- Crumbling sand mastic round a window
- Mastic that needs renewing before redecorating
- Gaps between timber frames and stone or brick
Homes close to St Mary's Church include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

The process
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, carry out the job and tidy away. Most jobs take anything from a few hours to a full day, depending on how many windows. Somewhere as small as Ashwell End, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking each surround and agreeing the joints to renew.
- We rake out the old mastic and clean the joint.
- Large voids are packed out first, so the mastic isn’t too thick.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Before we arrive
- Clear items away from the joints we’re working on
- On commercial sites, let us know about site rules
- Tell us if parking is tricky

How do I get a quote for sand mastic in Ashwell End?
It depends on the job, so we quote each one individually. For a quick quote, ring 0345 464 0079 or drop us an email with a short description of the job.
Will the old sealant be removed?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Do you have insurance?
Yes. We are fully insured.
How long will you be here?
That depends on the amount of work, but as a guide it takes anything from a few hours to a full day, depending on how many windows. We’ll tell you when we quote.
Is it possible to paint over sand mastic?
The usual advice is to leave sand mastic unpainted. Ask us before you decorate around it and we will advise.
Can I add another job to the visit?
Yes. Several rooms, windows or areas can go on one quote.
What happens if it’s left?
Before painting the windows, it pays to renew the mastic. Painting over failed mastic does not seal it and traditional guidance is to leave the new mastic unpainted. Older cottages and farmhouses around Ashwell End can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and give you a clear quote before any work starts.

How the job changes by surface
Brick reveals
Loose mastic comes out and deep gaps are packed before pointing.
Tenement and terrace windows
Where a building is shared, window work may involve neighbours, so check who is responsible first.
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Have rotten timber repaired before new mastic goes in
- Clear gutters so water doesn’t pour onto the windows
- Leave the new mastic unpainted
- Plan mastic work ahead of painting
Make sure water drains away from the window surround. Water sitting against the mastic shortens its life.
Sound mastic protects the frame. Failed mastic lets water reach the timber and timber that stays wet can rot.
