About our sand mastic in Ealing
Our applicators renew the sand mastic around sash and case windows and doors in stone and brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. We work on brick reveals, tenement windows and sash and case windows, and the jobs we see most are old cement repairs round a window that have failed and open joints round the window box.
London’s Victorian and Edwardian terraces were built with timber sash windows, and many still have them or their replacements. Either way, the mastic between frame and brickwork is what stops draughts and rain getting in, in Ealing as anywhere.
Your job is guaranteed for a year, as with all our work.

Aftercare tips
After the cure time, these simple habits help:
- Go gently near the mastic when preparing windows
- Leave the new mastic unpainted
- Keep modern sealant off the mastic
- Find out about consent before window work on a listed home
Leave the new mastic alone while it firms up. It forms a skin fairly soon, but takes longer to harden fully.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
What we can’t put right
It helps to know what we can’t do:
- Sashes that need overhauling

What the job involves on each surface
Period and listed homes
A traditional finish suits a period property.
Timber door frames
A neat sand mastic joint round a front door suits a period home.
Why deal with it now?
Silicone might seem the quicker option, but on period stone or brick it often looks out of place. Sand mastic is the traditional material and blends with the stone or brick. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble for homes in Ealing.

Can I do it myself?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.

FAQs for Ealing
Is Ealing in your area for sand mastic?
Yes. We work across London and the South East, and Ealing is part of that. You can call 0345 464 0079 or email us and let us know what needs doing, and we’ll send you a clear quote.
Is parking a problem for a job in Ealing?
Parking in Ealing, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
Can you seal over the old sealant?
No, and we never do. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
How do I get a quote for sand mastic in Ealing?
It depends on the job, so we quote each one individually. For a quick quote, ring 0345 464 0079 or send us an email with a short description of the job.
I rent my home. Can I book you?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.
Will you leave a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
How long does the job take?
It depends on the size of the job, but as a guide it takes a few hours for a single window, longer for several. We’ll give you a better idea when we quote.

- 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.
- Large voids are packed out first, so the mastic is not too thick.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The mastic is finished to sit tidily against the stone or brick.
Preparing for the visit
- Mention any tricky access
- Where the joints are inside, avoid wetting them before we arrive
