How we handle sand mastic in Salehurst
Old sand mastic cracks, crumbles and falls out over time and gaps open up round the frame. Renewing it closes the gap and tidies the surround. We’re often asked to deal with mastic dropping out of the joint and window mastic to renew ahead of painting, on period & listed homes, brick reveals and tenement windows.
Mastic can only go onto a dry, clean joint, so window work in Salehurst is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
You’re covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or send us an email.

The process
Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take anything from a few hours to a full day, depending on how many windows. In a small place like Salehurst, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check the window surrounds and agree which joints need renewing.
- Old, loose mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The finish is dressed so it sits neatly against the stone or brick.
Before we arrive
- Keep pets and children clear of the area while we work
- For business premises, tell us about site rules or sign-in
- Let us know about stairs, lifts or work at height

What else we do in Salehurst
Can I do it myself?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Why act early in Salehurst
Filling over old, loose mastic does not last. We remove the loose material first so the new work lasts. Older cottages and farmhouses around Salehurst can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Make sure water runs off the sill
- Ask the planning authority about consent for listed or conservation-area homes
- Take care around the mastic when scraping paint
- Leave the new mastic unpainted
Keep gutters and sills clear so water runs away from the surround. Water sitting against the mastic shortens its life.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens.
Salehurst homes and the weather
Historic houses like Durhamford Manor (about 3.7 miles south) are a reminder that the area around Salehurst 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. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For landlords with property near Robertsbridge station, cracked sand mastic around sash windows lets in the draughts tenants complain about. If you look after a building such as Salehurst Church of England Primary School, its window and door frames need their mastic kept sound, just like a home’s.
