Why it’s worth doing now in East Chiltington
Not every filler suits an old window surround. Sand mastic is the like-for-like choice and that can be important for listed homes. Around East Chiltington, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts.

About our sand mastic in East Chiltington
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. If you have patchy fillers round a sash window and mastic round period door frames that has failed, we can put it right, on tenement windows, brick reveals and stone surrounds alike.
In a village or hamlet like East Chiltington, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
There’s a 12-month guarantee on every job, whatever its size.

Can I do it myself?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.
Some sealant jobs are within reach of a careful DIYer, 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.

Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we’ll give you a quote.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Windows and doors in East Chiltington
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Anne of Cleves House (about 4.3 miles south-east) are a reminder that the area around East Chiltington has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.

What the job involves on each surface
Brick reveals
An open joint at a brick reveal lets weather in. New mastic seals the gap.
Stone surrounds
Stone surrounds suit sand mastic well. It finishes to look like part of the surround.
Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Ask a joiner to look at soft timber first
- Take care around the mastic when scraping paint
- Avoid patching sand mastic with silicone
- Look over the window mastic once a year
Leave the new mastic alone while it firms up. It forms a skin fairly soon but needs longer to fully harden.
An open joint round the box lets weather through. Left, the gap tends to get bigger as more mastic falls out.
What happens on the day
All our tools and materials come with us in the van. Once we’ve agreed what’s being done, the area is protected and the work begins. Most jobs take a few hours for a single window, longer for several. Somewhere as small as East Chiltington, 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.

Advice
When to call us in East Chiltington
Water gets into small cracks in the mastic and loosens it further. Windows facing the weather tend to go first.
The most common problems we see are:
- Tired mastic found when preparing windows for paint
- A silicone bead on a sash window that spoils the look
- Gaps where the frame meets the masonry
- Cracked mastic round a front door frame
For site and facilities teams at buildings such as Plumpton Primary School, its window and door frames need their mastic kept sound, just like a home’s.
