Sand mastic for sash & case windows in East Shalford, Surrey
We cover East Shalford for traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old material cut out, joints cleaned and sealed neatly and a one-year guarantee.
- Draughty sash windows at the surround
- Mastic dropping out of the joint
- Mastic round period door frames that has failed
Aftercare tips
So the new joints stay in good condition:
- Find out about consent before window work on a listed home
- Ask us before painting near the mastic
- Go gently near the mastic when preparing windows
- Clear gutters so water doesn’t pour onto the windows
Keep paint scrapers and sanders off the mastic when redecorating. Hard scraping can loosen it.
Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.
Sand mastic in East Shalford
For a listed home or one in a conservation area, ask your local planning authority whether consent is needed for work to windows. Sand mastic is often favoured as a like-for-like material. Common call-outs are for wind and rain getting in round a sash window and mastic worn away on windows facing the weather, on brick reveals, sash and case windows and period & listed homes.
Homes in small places like East Shalford often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
We stand behind the work with a 12-month guarantee, so you’re not left on your own once the job is done.

How it works
At the end, we look at the finished work together and explain the cure time. 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. Somewhere as small as East Shalford, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- 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.
Getting ready for the visit
- Mention any tricky access
- Tell us about any previous sealing or DIY attempts
- Mention any leaks or damp you’ve noticed

Advice
Landlords, agents and businesses in East Shalford
Letting agents often deal with us directly. Tell us the address, the job and how access works and we will quote.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
Leave it or put it right?
Before painting the windows, it pays to renew the mastic. Painting over failed mastic doesn’t seal it and traditional guidance is to leave the new mastic unpainted. Where a wall is exposed, as many are in small places like East Shalford, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.

Common questions in East Shalford
Will you come out to East Shalford?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you do sand mastic in East Shalford?
Yes, East Shalford is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear price.
Where is Mr Mastic based?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Can new sealant go over the old?
No, and we never do. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Is there any odour?
There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.
How long will you be here?
As a guide, most jobs take a few hours for a single window, longer for several. Bigger jobs take longer, and we’ll tell you how long to expect.
Can I paint the new mastic?
Traditional guidance is not to paint over sand mastic. If you’re redecorating the window, ask us first and we’ll advise.
Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, 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.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Frames and glazing around East Shalford
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Chilworth Manor (about 0.9 miles east) nearby, there’s older building stock in the area around East Shalford as well as newer homes. 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.
Homes close to Church of St Thomas include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in. Letting a property close to Shalford station? Then any sash windows need sound mastic to keep draughts and rain out. For site and facilities teams at buildings such as Tillingbourne Junior School, its window and door frames need their mastic kept sound, just like a home’s.
