Sand mastic in Palmer's Green, done properly
We renew sand mastic around sash windows and doors set in stone or brick. The old mastic is raked out, and new mastic is applied and shaped by hand. We are often asked to deal with old cement repairs round a window that have failed and gaps between timber frames and stone or brick, across period & listed homes, timber door frames and brick reveals.
In a village or hamlet like Palmer's Green, 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.
You are covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or drop us an email.

When to call us in Palmer's Green
Shallow joints are a common cause. A thin layer doesn’t hold well, which is why we pack deep voids first and get the depth right.
People normally contact us after spotting something like this:
- Silicone on a period window that looks wrong
- Open joints round the window box
- Wind and rain getting in round a sash window
- Mastic dropping out of the joint
Homes close to Parish Church of All Saints include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

- How the joint is cleaned and prepared

Questions from Palmer's Green
Will you come out to Palmer's Green?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you help a landlord with a rental near Paddock Wood station?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we will send you a clear quote.
Can you replace silicone on a period window with sand mastic?
In most cases. The silicone is cut out and the joint cleaned before the sand mastic goes in.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
What exactly is sand mastic?
It’s sand mixed with a linseed-oil-based binder for the joint between timber frames and masonry.
Do you hold any approvals?
Yes. We are approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
Do you remove the old sealant?
Yes, always, and completely. New silicone does not stick to old silicone, so the joint is cleaned back first.
Do I need to be at home?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
Why act early in Palmer's Green
New mastic over crumbling mastic will not hold. We remove the loose material first so the new work lasts. Older cottages and farmhouses around Palmer's Green can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

What we can’t put right
We will always be straight with you, so here’s what new sealant will not do:
- Sashes that need overhauling
- Planning or listed building consent (your local planning authority decides)
- Rotten sashes, sills or window boxes (a joiner’s job)
Not sure which it is? You can ring 0345 464 0079 or send us an email and we’ll tell you honestly before booking.

What we do, step by step
We keep the work tidy and contained to the area we’re working on, so you can carry on as normal. Expect the work to take anything from a few hours to a full day, depending on how many windows, and we tell you how long to leave it before we go. Somewhere as small as Palmer's Green, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking each surround and agreeing the joints to renew.
- We rake out the old mastic and clean the joint.
- Deep voids are packed so the mastic is the right thickness.
- The mastic is mixed, pressed into the joint by hand and shaped.
- We dress the surface so it sits neatly against the masonry.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Mention any sign-in or site rules at work premises
- Clear items away from the joints we’re working on

Advice
Sand mastic in Palmer's Green: local notes
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Scotney Castle (about 4 miles south) nearby, there’s older building stock in the area around Palmer's Green as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you let a flat or house near Paddock Wood station, any sash windows need sound mastic to keep draughts and rain out. Managing a site like Brenchley and Matfield Church of England Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.

What affects the cost of sand mastic
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Whether old sealant or filler has to be cut out
- Working hours on commercial sites
- The number of rooms or windows
- Whether there’s mould to deal with
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
What we need to know
Before you ask for a quote, have a think about:
- What the problem is, such as mould, gaps, leaks or cracking
- How many joints, rooms or windows are involved
- Whether it’s a home or a business
- Where the property is

Aftercare tips
Good habits help new joints last longer. Our tips:
- Ask a joiner to look at soft timber first
- Find out about consent before window work on a listed home
- Plan mastic work ahead of painting
- Avoid patching sand mastic with silicone
Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.
Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.
