How we handle sand mastic in Bunce Common

On period homes, it looks right where silicone wouldn’t. We’re often asked to deal with mastic that needs renewing before redecorating and mastic round period door frames that has failed, on stone surrounds, tenement windows and timber door frames.

What happens if it’s left?
If you’re redecorating, renew the mastic first. Paint over cracked mastic won’t stop the gaps, and the new mastic is traditionally left unpainted. In a small place like Bunce Common, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re unsure, call 0345 464 0079 or email us for an honest opinion and a quote.

Advice
Common problems we fix in Bunce Common
Over the years, sand mastic weathers. It hardens, cracks and starts to come away from the frame or the masonry.
These are the problems we’re asked about most:
- Tired mastic found when preparing windows for paint
- Draughts and rain around sash boxes
- Old sand mastic that has cracked, crumbled or fallen out
- Gaps between timber frames and stone or brick
For landlords with property near Betchworth station, older sash windows in a rental need their mastic kept sound to keep the weather out.
What your quote should include
- Whether the sealant suits the joint
- What insurance they hold
- Who does the work, and how experienced they are
- How the colour is chosen
How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Sort the mastic before the decorators arrive
- Avoid heavy scraping on the mastic joint
- Look over the window mastic once a year
- Don’t paint over the new mastic
Leave the new mastic unpainted, as traditional guidance advises. Ask us before any decorating around it.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber and timber that stays wet can rot.
How we quote for sand mastic
Every job gets its own quote. These are the things that affect it:
- Any mould that needs treating
- The product the joint needs
- Access and height
- The number of rooms or windows
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
