Sand mastic in Moss End
Across Moss End, we renew sand mastic around sash and case windows. Every joint is cleaned out and filled by hand for a neat, traditional finish. If you have modern sealant on a period surround and failed mastic on an exposed elevation, we can help.
Around Moss End, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
Whatever the size of the job, it’s backed by our one-year guarantee in Moss End and across Bracknell Forest.

Moss End: your questions answered

Yes, we work for landlords and agents. You can ring 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before any work starts.
Does someone need to be in?

The usual advice is to leave sand mastic unpainted. Ask us before you decorate around it and we’ll advise.
Is it messy?

Do you hold any approvals?

Should I check with the council before work on a listed or conservation-area home?
Check with your local planning authority. They decide whether consent is needed for work to your windows.
What we’re called out for in Moss End
Some old mastic was never deep enough. A thin layer does not hold well, which is why we pack deep voids first and get the depth right.
If you can see any of these, it’s time to have the joints looked at:
- Wind and rain getting in round a sash window
- Patchy fillers round a sash window
- Gaps between timber frames and stone or brick
- Mastic round period door frames that has failed
For an older house near a landmark such as Church of St Michael and All Angels, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
Before booking anyone
- How long to leave it before use
- Which colour the sealant will be
- What product goes in the joint
- Is the old sealant removed completely?
Should I try it myself first?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Leave it or put it right?
Gaps round a sash window let in rain and draughts. Left, water can reach the timber and the wall, so dealing with it now protects both. Older cottages and farmhouses around Moss End can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

What the job involves on each surface
Brick reveals
An open joint at a brick reveal lets weather in. Renewing the mastic closes it.
Stone surrounds
Stone openings are rarely perfectly straight, so the gap is not the same all the way round. We shape it by hand to follow the stone.
Moss End homes and the weather
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like St Leonard's Hill (about 4.5 miles east) are a reminder that the area around Moss End has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
For landlords with property near Bracknell station, older sash windows in a rental need their mastic kept sound to keep the weather out. For site and facilities teams at buildings such as Garth Hill College, the mastic around its windows and doors needs looking after like any other building’s.

The process
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. It normally takes anything from a few hours to a full day, depending on how many windows. Somewhere as small as Moss End, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at the surrounds with you and agree the joints to renew.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
How to prepare
- Mention if the joints have been sealed before
- Mention any sign-in or site rules at work premises
- Mention any tricky access
