Sand mastic in Ilford
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s a mix of sand and a linseed-oil-based binder, applied by hand. On older homes, it suits the building far better than silicone. We’re often asked to deal with mastic that needs renewing before redecorating and cement or filler used on old window joints that has cracked, across brick reveals, stone surrounds and sash and case windows.
Many London homes are flats, with windows high above the street. In a converted house or block, the lease usually says who is responsible for the windows, so it’s worth checking before booking.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Why it’s worth doing now in Ilford
A silicone bead can be quicker, but on period stone or brick it often looks out of place. Sand mastic suits the building and blends with the stone or brick. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in Ilford, the repair is bigger than the sealant job would have been.
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and agree the price before starting.
Why book with us
- Full insurance on every job
- Trusted Arbo and Everbuild sealants

Other services in Ilford
Should I try it myself first?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
When to call us in Ilford
Decorating can disturb tired mastic. It’s often found when windows are being prepared for paint.

Sand mastic in Ilford: local notes
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Valentines Mansion (about 0.9 miles north-west) are a reminder that the area around Ilford has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
