Sand mastic in Woolhampton
Across Woolhampton, we renew sand mastic around sash and case windows. Every joint is cleaned out and filled by hand, finished to suit the masonry. We work on period & listed homes, timber door frames and tenement windows, and people most often call us about open joints round the window box and crumbling sand mastic round a window.
In a village or hamlet like Woolhampton, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

What the job involves on each surface
Stone surrounds
Sand mastic sits naturally against stone. The finish blends with the masonry.
Timber door frames
Sand mastic is used round timber door frames too. The method is the same as for windows.
How it works
At the end, we look at the finished work together and tell you how long to leave it. The work normally takes anything from a few hours to a full day, depending on how many windows, depending on how much there is to do. In a small place like Woolhampton, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we look at the surrounds with you and agree what needs doing.
- Old, loose mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- We dress the surface so it sits neatly against the masonry.
Before we arrive
- Let us know about stairs, lifts or work at height
- Keep pets and children clear of the area while we work
- Tell us about any water getting in

How to look after the new joints
After the cure time, these simple habits help:
- Get any rot dealt with first
- Avoid heavy scraping on the mastic joint
- Renew mastic before redecorating the windows
- Leave the new mastic unpainted
Keep paint scrapers and sanders off the mastic when redecorating. 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.
Signs you need sand mastic in Woolhampton
Age is the main cause. Even well-laid mastic needs renewing in time and how long it lasts depends on the weather it faces.
Keep an eye out for any of the following:
- A silicone bead on a sash window that spoils the look
- Gaps round a timber door in stone or brick
- Crumbling sand mastic round a window
- Failed mastic on an exposed elevation
If you live in an older home near Church of St Peter, the joint between an old wall and a newer frame is generally the first place rain gets in.

Why it’s worth doing now in Woolhampton
Replacing sash windows is a big decision for a period home, and in listed buildings it may need consent. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. In a small place like Woolhampton, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
What you pay reflects the work, not a rough estimate. That is why we ask about the job first and send you a clear quote before we start.
