About our sand mastic in Woodlands St Mary
Silicone on a period window often looks wrong and isn’t always the right material. Sand mastic is the traditional choice, and we can replace one with the other. We work on timber door frames, stone surrounds and sash and case windows, and the jobs we see most are mastic that needs renewing before redecorating and mastic dropping out of the joint.
Somewhere as small as Woodlands St Mary, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
There’s a 12-month guarantee on every job, whatever its size.

What affects the cost of sand mastic

- The size of the job
- Any working-time requirements on site
- How easy the joints are to reach
- How much old sealant there is and how hard it is to remove
What it costs depends on how much there is to do, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.
What we need to know
To make quoting easier, let us know:
- Pictures of the joints, sent by email
- Whether it’s a home or a business
- If someone has resealed it before
- The problem you’ve noticed
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that is easy.
Why act early in Woodlands St Mary
Not every filler suits an old window surround. Sand mastic matches what was there and that can be important for listed homes. Older cottages and farmhouses around Woodlands St Mary can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Combining jobs into one visit is generally more efficient than separate visits. We’ll give you a clear quote for the lot.

Advice
Frames and glazing around Woodlands St Mary
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.
For an older house near a landmark such as St Mary's Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Rented homes near Hungerford station change hands often, and any sash windows need sound mastic to keep draughts and rain out.

What information do you need?

Is it worth trying it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Clear gutters so water doesn’t pour onto the windows
- Ask us before painting near the mastic
- Have rotten timber repaired before new mastic goes in
- Avoid patching sand mastic with silicone
When preparing windows for paint, take care around the mastic. It can be damaged by heavy scraping.
Gaps round a sash box let in draughts and rain. Left, the gap tends to get bigger as more mastic falls out.
