Sand Mastic in Little Kingshill
Problem with your window and door surrounds in Little Kingshill? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.
- Mastic dropping out of the joint
- Cement or filler used on old window joints that has cracked
- Draughty sash windows at the surround
How the job changes by surface
Brick reveals
Gaps between frame and brick let in rain and draughts. New mastic seals the gap.
Stone surrounds
Sand mastic sits naturally against stone. It finishes to look like part of the surround.
Sand mastic for homes and businesses in Little Kingshill
We renew sand mastic around sash windows and doors in stone and brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. Typical jobs include cement or filler used on old window joints that has cracked and tired mastic found when preparing windows for paint, on sash and case windows, brick reveals and timber door frames.
Homes in small places like Little Kingshill often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

Questions from Little Kingshill
Do you work for landlords with property near Great Missenden station?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can go on one quote. You can call 0345 464 0079 or email us with the details for a clear quote.
Can you do sand mastic in Little Kingshill?
Yes. We work across London and the South East, and Little Kingshill is part of that. You can ring 0345 464 0079 or email us and tell us what needs doing.
Is it OK to seal over old sealant?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. It all has to come out first.

Where are you based?
We work from Crawley. We cover Little Kingshill and the rest of Buckinghamshire.
What exactly is sand mastic?
It’s a mix of sand and a linseed-oil-based binder. It’s built up in the joint by hand and shaped to suit the surround.

Tell us what needs doing and where, with photos by email if possible. We’ll ask anything else we need to know.
Can you quote for more than one area?

Honest limits
Some problems need a builder, plumber or other trade rather than us:

Common problems we fix in Little Kingshill
Some old mastic was never deep enough. A thin layer doesn’t hold well so we make sure the new mastic is the right thickness.
It’s worth asking for a quote if you see:
- Silicone on a period window that looks wrong
- Cracked mastic round a front door frame
- Weathered mastic on the most exposed windows
- Gaps between timber frames and stone or brick
In the older streets around Church of Saints Peter and Paul, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Windows and doors in Little Kingshill
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Hughenden Manor (about 3.5 miles south-west) nearby, there’s older building stock in the area around Little Kingshill as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Letting a property close to Great Missenden station? Then older sash windows in a rental need their mastic kept sound to keep the weather out. If you look after a building such as Ash Hill Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Keep modern sealant off the mastic
- Find out about consent before window work on a listed home
- Clear gutters so water doesn’t pour onto the windows
- Do not paint over the new mastic
Look at the mastic when you look over the windows. Small cracks are easier to deal with early.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.
