Sand mastic in Bowlhead Green, done properly
Old sand mastic cracks, crumbles and falls out over time and gaps open up round the frame. We rake it out and renew it and tidies the surround. We work on timber door frames, tenement windows and stone surrounds, and people most often call us about open joints round the window box and cracked mastic round a front door frame.
Homes in small places like Bowlhead Green 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.
Each job carries a 12-month guarantee, large or small.

Signs you need sand mastic in Bowlhead Green
Decorating can disturb tired mastic. Many people find it crumbling when they prepare the windows, which is a good time to renew it.
Any of these means the joints need attention:
- Cracked mastic round a front door frame
- Modern sealant on a period surround
- Mastic that needs renewing before redecorating
- Gaps where the frame meets the masonry
In the older streets around 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.

- Whether the sealant suits the joint

- When the joint can take water or movement
What happens if it’s left?
Replacing sash windows is a big decision for a period home, and in listed buildings it may need consent. Where the frames are in good order, new mastic seals the surround. Where a wall is exposed, as many are in small places like Bowlhead Green, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

Questions from Bowlhead Green
Is Bowlhead Green within the area you cover?
Yes, Bowlhead Green is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you cover Bowlhead Green for sand mastic?
Yes. We work across London and the South East, and Bowlhead Green is part of that. You can phone 0345 464 0079 or send us an email and tell us what needs doing.
Is it OK to seal over old sealant?
No, it will not last. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.
Is it possible to take out silicone and use sand mastic instead?
Often, yes. With the silicone removed and the joint cleaned we point it with sand mastic.
Can you match the sealant colour?
We will suggest a colour to suit the surroundings. The product needed can limit the range.
Are you insured?
Yes, we’re fully insured for every job we do.
Do you do commercial work?
Yes. We’ve worked for hotels, offices and other businesses and we are fully insured.
What sealant do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
What sealant work can’t fix
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Masonry that needs repairing
- Whether work needs listed building consent
- Sash cords, weights and draught-proofing of the sashes
Not sure which it is? You can ring 0345 464 0079 or send us an email and we’ll tell you honestly.

How the job changes by surface
Sash and case windows
The box of a sash and case window sits in the stone or brick opening. The gap round it is pointed with sand mastic.
Brick reveals
Sand mastic is also used where timber frames meet brick. It suits older brickwork.
Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Renew mastic before redecorating the windows
- Do not run silicone over sand mastic
- Find out about consent before window work on a listed home
- Ask us before painting near the mastic
Make sure water drains away from the window surround. Constant wetting wears the mastic faster.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber and timber that stays wet can rot.

After that, the work takes a few hours per window, depending on the condition of the joints. Somewhere as small as Bowlhead Green, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we look at the surrounds with you and agree what needs doing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
