Sand mastic for homes and businesses in Eastwick
Burnt sand mastic is a traditional material blends with stone and brick surrounds. It’s a good fit for period properties, where modern sealant can look out of place. If you’re dealing with tired mastic found when preparing windows for paint and cement or filler used on old window joints that has cracked, we can help, on sash and case windows, brick reveals and tenement windows alike.
In a village or hamlet like Eastwick, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
The work is covered for a year after we finish. If anything is not right with it, phone 0345 464 0079 or email us.

Signs you need sand mastic in Eastwick
Water gets into small cracks in the mastic and loosens it further. Windows facing the weather tend to go first.
Common reasons people contact us include:
- Weathered mastic on the most exposed windows
- Mastic dropping out of the joint
- Gaps round a timber door in stone or brick
- Patchy fillers round a sash window
Homes close to Church of St Botolph include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in.

Frames and glazing around Eastwick
Harlow, which Eastwick 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. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Letting a property close to Harlow Town station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about. For site and facilities teams at buildings such as Pemberley Academy, its window and door frames need their mastic kept sound, just like a home’s.

DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
