How we handle sand mastic in Little Barrington
Sand mastic does not last for ever and gaps open up round the frame. We rake it out and renew it so the surround looks right again. We work on period & listed homes, sash and case windows and brick reveals, and people most often call us about wind and rain getting in round a sash window and gaps round a timber door in stone or brick.
Mastic can only go onto a dry, clean joint, so window work in Little Barrington is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
You’re covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or send us an email.

Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
When to call us in Little Barrington
Most of it is simply age. Sand mastic is a maintenance item like any pointing, depending on exposure and upkeep.
The problems people usually mention when they call are:
- Wind and rain getting in round a sash window
- Gaps between timber frames and stone or brick
- Gaps round a timber door in stone or brick
- Weathered mastic on the most exposed windows
Homes close to Church of St Peter include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.
What to look for in a quote
- Is VAT in the price?
- When the joint can take water or movement
- How the surfaces are prepared before sealing
- Whether they seal over old material or remove it
How the job changes by surface
Timber door frames
Door frames get knocked and soaked and the mastic can crack early. We rake it out and renew it.
Sash and case windows
Most of our sand mastic work is on sash windows. We renew the mastic round each box.
What we do, step by step
At the end, we look at the finished work together and tell you how long to leave it. The work normally takes a few hours for a single window, longer for several, depending on the amount of work. Somewhere like Little Barrington needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
Before we arrive
- Mention any tricky access
- Tell us about any water getting in
- Keep pets and children clear of the area while we work
