Sand mastic in Hawkley
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s made from sand and a linseed-oil-based binder, applied by hand. On period homes, it looks right where silicone wouldn’t. We are often asked to deal with cracked mastic round a front door frame and open joints round the window box, across tenement windows, sash and case windows and brick reveals.
Mastic can only go onto a dry, clean joint, so window work in Hawkley is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

How to look after the new joints
Aftercare is simple:
- Take care around the mastic when scraping paint
- Get any rot dealt with first
- Avoid patching sand mastic with silicone
- Renew mastic before redecorating the windows
Do not run silicone over the new mastic. If you see a crack, ask us to take a look rather than patching it.
Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.
What affects the cost of sand mastic
There’s no set price list. The quote depends on:
- The size of the job
- The type of sealant required
- Mould in or behind the old joints
- Working hours on commercial sites
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.
What to tell us for a quote
Photos help, but a description is a good start. Try to tell us:
- The rough size of the job
- Where the job is, and your postcode
- Whether it has been sealed before
- The problem you’ve noticed
We do not publish a price list. Instead, we give you a clear quote for your job. To get started, phone 0345 464 0079 or drop us an email.
Signs you need sand mastic in Hawkley
Previous repairs in cement or silicone often trap water or crack away. They do not move with the timber and we normally remove them.
If you can see any of these, it’s time to have the joints looked at:
- Gaps where the frame meets the masonry
- Patchy fillers round a sash window
- Window mastic to renew ahead of painting
- Draughty sash windows at the surround
Homes close to Church of St Peter and St Paul include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Leave it or put it right?
Not every draught comes from the sashes themselves. Gaps between the frame and the wall can be just as bad and new mastic seals them. Where a wall is exposed, as many are in small places like Hawkley, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we will go through it with you.
