About our sand mastic in Nevendon
Traditional burnt sand mastic blends with stone and brick surrounds. It suits period and listed homes where a modern sealant bead would stand out. If you have old cement repairs round a window that have failed and cracked mastic round a front door frame, we can put it right, on tenement windows, period & listed homes and brick reveals alike.
Around Nevendon, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
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.

How it works
At the end, we look at the finished work together. The visit itself generally takes a few hours per window, depending on the condition of the joints, depending on the size of the job. Somewhere as small as Nevendon, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each surround is checked first.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic is not too thick.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- Keep pets and children clear of the area while we work
- For business premises, tell us about site rules or sign-in

Why act early in Nevendon
Silicone might seem the quicker option, but on period stone or brick it often looks out of place. Sand mastic suits the building and finishes neatly against the masonry. Where a wall is exposed, as many are in small places like Nevendon, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
We do not show prices on the website, because each job is priced on what it involves. Call for a quick quote.

For an older house near a landmark such as Church of All Saints, frames set in older brick or stone need a sealant that suits the wall as well as the frame. If you let a flat or house near Wickford station, any sash windows need sound mastic to keep draughts and rain out.
