Sand mastic for sash & case windows in Broad Oak, Kent
Our applicators work in Broad Oak on traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old sealant removed completely, joints prepared properly.
- Modern sealant on a period surround
- Draughts and rain around sash boxes
- Cracked mastic round a front door frame
How it works
There isn’t much for you to do on the day. Point us to the joints and we will get on with it. The job generally takes a few hours per window, depending on the condition of the joints. Somewhere as small as Broad Oak, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check the window surrounds and agree which joints need renewing.
- Old, loose mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic isn’t too thick.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Preparing for the visit
- Clear the area around the work
- Keep pets and children clear of the area while we work
- Tell us about any previous sealing or DIY attempts

Sand mastic in Broad Oak
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. If you have open joints round the window box and weathered mastic on the most exposed windows, we can help, on stone surrounds, tenement windows and brick reveals alike.
Mastic can only go onto a dry, clean joint, so window work in Broad Oak is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
All our work comes with our 12-month guarantee, wherever you are in Kent.

Broad Oak: your questions answered
Is Broad Oak in your area for sand mastic?
Yes. Our work covers London and the South East, and Broad Oak is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear price.
Is Broad Oak within the area you cover?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can new sealant go over the old?
No, it won’t last. 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.
How long does the job take?
It depends on the size of the job, but most jobs take anything from a few hours to a full day, depending on how many windows. We’ll give you a better idea when we quote.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
Will there be a smell?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
Are you insured?
Yes. We are fully insured for domestic and commercial work.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done.

Windows and doors in Broad Oak
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.
Rented homes near Sturry station change hands often, and any sash windows need sound mastic to keep draughts and rain out. For an older house near a landmark such as St Nicholas' Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you look after a building such as Sturry Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s.

Aftercare tips
A little care helps the new joints last. Our advice:
- Sort the mastic before the decorators arrive
- Inspect the joints round the windows every year or so
- Find out about consent before window work on a listed home
- Make sure water runs off the sill
Leave the new mastic unpainted, as traditional guidance advises. Ask us before any decorating around it.
Renewing mastic before redecorating saves doing it twice. Painting over failed mastic hides the problem for a while.
When something else is needed
We’ll always be straight with you, so here’s what new sealant will not do:
- Putty and glazing repairs
- Crumbling stone or brickwork round the window
- Sashes that need overhauling
If in doubt, call 0345 464 0079 or send us an email and we will say what we think before booking.

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 the new mastic is traditionally left unpainted. Older cottages and farmhouses around Broad Oak can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
The cost depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins.
