About our sand mastic in Pond Park
Burnt sand mastic is a traditional material that sits naturally against stone and brick. It’s a good fit for period properties, where modern sealant can look out of place. We’re often asked to deal with cracked mastic round a front door frame and crumbling sand mastic round a window, across brick reveals, stone surrounds and period & listed homes.
Around Pond Park, conservatories, garden rooms and patio doors are often part of the house. Their glazing joints and frame seals are as much a part of the job as the windows, and any older timber or sash windows need a sealant that suits them.
Whatever the size of the job, you get the same one-year guarantee in Pond Park and across Buckinghamshire.

How the visit works
Once we are on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes a few hours per window, depending on the condition of the joints. Parking around Pond Park is normally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- We check the window surrounds and agree which joints need renewing.
- We rake out the old mastic and clean the joint.
- Deep voids are packed so the mastic is the right thickness.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Before we arrive
- Keep children and pets away from the work area
- Let us know if you’ve seen damp or leaks
- Mention any tricky access

- Where the property is
We quote each job on its own, so the first step is telling us about yours. Simply call 0345 464 0079 or email us and describe the job, and pictures are welcome.
What sealant work cannot fix
To be straight with you, some problems need a different trade:
- Sashes that rattle, stick or will not open
- Crumbling stone or brickwork round the window
- Rotten sashes, sills or window boxes (a joiner’s job)
Not sure which it is? You can call 0345 464 0079 or send us an email and we’ll tell you honestly.
Surfaces we seal
- Sash and case windows
- Tenement windows
- Stone surrounds
- Brick reveals
- Period & listed homes
- Timber door frames
Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Have rotten timber repaired before new mastic goes in
- Avoid heavy scraping on the mastic joint
- Sort the mastic before the decorators arrive
- Avoid patching sand mastic with silicone
Make sure water drains away from the window surround. Constant wetting wears the mastic faster.
Sound mastic protects the frame. Once it fails, water can sit against the timber, which can lead to rot.
For landlords and businesses
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
For anyone letting property in or around Pond Park, jobs at different addresses can go on one quote. Just tell us the addresses and what each one needs.
Surface by surface
Stone surrounds
Stone openings are rarely perfectly straight, so the joint varies in width. Sand mastic is shaped by hand to suit.
Sash and case windows
Sash windows are where we do most sand mastic work. Each joint round the box is raked out and renewed.
Signs you need sand mastic in Pond Park
Sand mastic slowly weathers. It dries out, cracks and loses its grip from the frame or the masonry.
These are the problems we are asked about most:
- Weathered mastic on the most exposed windows
- Mastic that needs renewing before redecorating
- Mastic dropping out of the joint
- Cracked mastic round a front door frame
If you let a flat or house near Amersham station, older sash windows in a rental need their mastic kept sound to keep the weather out.

Frames and glazing around Pond Park
With historic houses such as Cholesbury Manor House (about 3 miles north-west) nearby, there’s older building stock in the area around Pond Park as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. 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.
Historic houses such as Cholesbury Manor House, about 3 miles north-west, show how far back building around Pond Park goes. Managing a site like Ivingswood Academy? Then the mastic around its windows and doors needs looking after like any other building’s.

Common questions in Pond Park
Is Pond Park in your area for sand mastic?
Yes. Our work covers London and the South East, and Pond Park is part of that. You can ring 0345 464 0079 or drop us an email and tell us what needs doing, and we will send you a clear quote.
I let a flat near Amersham station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
When will the new mastic be hard?
It forms a skin fairly soon, then hardens over a longer period. Timing depends on the weather and the joint.
Do you remove the old sealant?
Yes, every time. New silicone does not stick to old silicone, so the joint is cleaned back first.
What’s sand mastic made of?
A traditional pointing material made from sand and a linseed-oil-based binder for the joint between timber frames and masonry.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status, and we are fully insured.
