Sand Mastic in Woodham Walter
We cover Woodham Walter for traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old sealant removed completely, joints prepared properly and a 12-month guarantee.
- Wind and rain getting in round a sash window
- Mastic round period door frames that has failed
- Window mastic to renew ahead of painting
How the job changes by surface
Stone surrounds
Stone openings are rarely perfectly straight, so the joint varies in width. Sand mastic is shaped by hand to suit.
Sash and case windows
A sash window’s box frame sits in the masonry opening. Sand mastic seals the joint round it.
How we handle sand mastic in Woodham Walter
Old sand mastic cracks, crumbles and falls out over time and gaps open up round the frame. We rake it out and renew it so the surround looks right again. Typical jobs include crumbling sand mastic round a window and gaps between timber frames and stone or brick, on stone surrounds, sash and case windows and brick reveals.
Mastic can only go onto a dry, clean joint, so window work in Woodham Walter is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

DIY sealant or a professional job?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

Your questions about sand mastic in Woodham Walter
Do you cover Woodham Walter for sand mastic?

Does someone need to be in?
It depends on the job. Inside work needs someone to give us access.
Do you take out the old sealant first?
Yes, always, and completely. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Where do you work from?
Our base is in Crawley, and we work across South East England, London and Scotland.
Is sand mastic better than silicone for my windows?
That depends on your windows. On many period windows, sand mastic looks right and suits the building, while modern frames normally get a flexible sealant.
Can I paint the new mastic?
It’s traditionally left unpainted, as guidance on traditional windows advises. Ask us before decorating.
Is it messy?
Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we are done.
What sealant work can’t fix
A few problems are outside what sealant work can do:

What happens if it’s left?
A silicone bead can be quicker, but it can look wrong on a period surround. Sand mastic suits the building and blends with the stone or brick. In a small place like Woodham Walter, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
The cost reflects the work involved, not guesswork. That is why we ask about the job first and give you a clear price before any work starts.

Sand mastic in Woodham Walter: local notes

Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

How to look after the new joints
Good habits help new joints last longer. Our tips:
- Ask us before painting near the mastic
- Keep sills and gutters clear so water drains away
- Check the mastic when you check the paintwork
- Check with your local planning authority if your home is listed
Leave the new mastic unpainted, as traditional guidance advises. If you’re redecorating, ask us first.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens as more mastic falls out.
