How we handle sand mastic in Amen Corner
Traditional burnt sand mastic blends with stone and brick surrounds. It suits period and listed homes, where modern sealant can look out of place. We are often asked to deal with cement or filler used on old window joints that has cracked and mastic that needs renewing before redecorating, on brick reveals, timber door frames and sash and case windows.
Homes around Amen Corner range from older properties to newer houses, and their windows range just as widely. The right sealant depends on the frame and on what it sits in.
The work is covered for a year after we finish. If anything isn’t right with it, call 0345 464 0079 or email us.

Windows and doors in Amen Corner
Bracknell, which Amen Corner is part of, is one of England’s post-war new towns. With many homes from the post-war decades, replacement windows and doors are common. The mastic around replacement frames ages too, and gaps at sills and frame heads are where water gets in. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Letting a property close to Bracknell station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about. If you look after a building such as Jennett's Park CofE Primary School, its window and door frames need their mastic kept sound, just like a home’s.

Your questions about sand mastic in Amen Corner
Should the sealant in an older Amen Corner home be renewed?
Often, yes: cracked, shrunken or mouldy sealant has done its job. New sealant won’t stick to old, so the old bead has to come out completely first.
Will you come out to Amen Corner?
Yes, Amen Corner is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before resealing.
Can new sealant go over the old?
No, it won’t last. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
Can I add another job to the visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
Is it messy?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Is consent needed for window work on a listed home?
Your local planning authority is the one to ask. They’ll tell you if consent is needed.
How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Make sure water runs off the sill
- Ask us before painting near the mastic
- Avoid patching sand mastic with silicone
- Plan mastic work ahead of painting
Keep paint scrapers and sanders off the mastic when redecorating. Hard scraping can loosen it.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber, which can lead to rot.
What we do, step by step
We bring everything the job needs with us, so there’s nothing for you to buy. Once we’ve agreed what’s being done, we protect the area and start. Most jobs take a few hours for a single window, longer for several. Parking around Amen Corner is normally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- We look at the surrounds with you and agree the joints to renew.
- 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.
Preparing for the visit
- Mention if the joints have been sealed before
- Where the joints are inside, avoid wetting them before we arrive
- Mention any sign-in or site rules at work premises

What we’re called out for in Amen Corner
Over the years, sand mastic weathers. It hardens, cracks and starts to come away from the frame or the masonry.
The most common problems we see are:
- Cement or filler used on old window joints that has cracked
- Draughty sash windows at the surround
- Gaps where the frame meets the masonry
- Window mastic to renew ahead of painting
In the older streets around Church of St Mark, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
