How we handle sand mastic in Sacombe Green
Across Sacombe Green, we renew sand mastic around sash and case windows. Every joint is cleaned out and filled by hand for a neat, traditional finish. We work on stone surrounds, sash and case windows and timber door frames, and the jobs we see most are mastic that needs renewing before redecorating and mastic dropping out of the joint.
Around Sacombe Green, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
You are covered for a year from the day we finish. If anything is not right with it, call 0345 464 0079 or email us.

Related advice
Landlord and commercial work in Sacombe Green
Letting agents and landlords in Sacombe Green can book us as well as householders. Sealant work between tenants keeps a property looking cared for.
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Should I try it myself first?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
If you’re set on DIY, put the effort into 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.
What happens if it’s left?
Silicone might seem the quicker option, but it can look wrong on a period surround. Sand mastic suits the building and blends with the stone or brick. Older cottages and farmhouses around Sacombe Green can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
What you pay reflects the work, not guesswork. That’s why we ask about the job first and give you a clear quote before work begins.

Signs you need sand mastic in Sacombe Green
Scraping and sanding before painting can loosen old mastic. Many people find it crumbling when they prepare the windows.
Any of these means the joints need attention:
- Draughty sash windows at the surround
- Weathered mastic on the most exposed windows
- Crumbling sand mastic round a window
- Silicone on a period window that looks wrong
Letting a property close to Watton-At-Stone station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about.

Sand mastic in Sacombe Green: local notes
Historic houses like Aston Bury (about 4.4 miles west) are a reminder that the area around Sacombe Green has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you look after a building such as Ralph Sadleir Middle School, larger buildings have plenty of frames, and the mastic around each one ages. If you live in an older home near Church of St Katherine, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

As a guide, most jobs take anything from a few hours to a full day, depending on how many windows. Bigger jobs take longer, and we’ll say how long yours will take.
Should I use sand mastic or silicone?
For period timber windows in stone or brick, sand mastic is often the better fit. On modern frames, we’d normally use a flexible sealant, and we’ll explain why.

There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
What exactly is sand mastic?
It’s a mix of sand and a linseed-oil-based binder. It’s built up in the joint by hand and finished to sit neatly against the masonry.
