About our sand mastic in Tyler's Hill
Traditional burnt sand mastic blends with stone and brick surrounds. It’s a good fit for period properties, where modern sealant can look out of place. Typical jobs include draughts and rain around sash boxes and mastic round period door frames that has failed, on tenement windows, sash and case windows and timber door frames.
Around Tyler's Hill, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Advice
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward 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: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Don’t run silicone over sand mastic
- Find out about consent before window work on a listed home
- Don’t paint over the new mastic
- Check the mastic when you check the paintwork
Leave the new mastic alone while it firms up. It skins over quickly, but takes longer to harden fully.
Sound mastic protects the frame. Failed mastic lets water reach the timber, which can lead to rot.
How we quote for sand mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- Working hours on commercial sites
- Any mould that needs treating
- Whether old sealant or filler has to be cut out
- The number and length of the joints
What it costs depends on the amount of work, how much old material has to come out and how easy the joints are to reach. We give a clear quote before any work starts.
Helping us quote
Photos help, but a description is a good start. Try to tell us:
- If it’s domestic, commercial or a hotel
- What the problem is, such as mould, gaps, leaks or cracking
- A few pictures by email, if you can
- Any previous sealing or DIY work
There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, call 0345 464 0079 or send us an email.

Leave it or put it right?
Replacing sash windows is a big decision for a period home and on a listed home, consent may be needed. Where the frames are in good order, new mastic seals the surround. Older cottages and farmhouses around Tyler's Hill can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

What sand mastic looks like in Tyler's Hill
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Chenies Manor House (about 3 miles south-east) are a reminder that the area around Tyler's Hill has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
For landlords with property near Amersham station, any sash windows need sound mastic to keep draughts and rain out. If you look after a building such as Ley Hill School, larger buildings have plenty of frames, and the mastic around each one ages.

Common problems we fix in Tyler's Hill
Over the years, sand mastic weathers. It dries out, cracks and loses its grip from the frame or the masonry.
Look out for any of the following:
- Window mastic to renew ahead of painting
- Open joints round the window box
- Mastic dropping out of the joint
- Weathered mastic on the most exposed windows
If you live in an older home near St George's Church, the joint between an old wall and a newer frame is generally the first place rain gets in.
