Frames and glazing around Swinbrook
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Minster Lovell Hall (about 2.9 miles south-east) nearby, there’s older building stock in the area around Swinbrook as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Letting a property close to Shipton station? Then any sash windows need sound mastic to keep draughts and rain out. For an older house near a landmark such as Church of St Mary, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Sand mastic in Swinbrook, done properly
Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant, and we will talk through which suits your home. We work on brick reveals, period & listed homes and timber door frames, and common reasons people get in touch are mastic that needs renewing before redecorating and gaps where the frame meets the masonry.
In a village or hamlet like Swinbrook, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
The work is covered for a year after we finish. If anything isn’t right with it, call 0345 464 0079 or drop us an email.

Common questions in Swinbrook
Do you work for landlords with property near Shipton station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or send us an email and tell us about the property, and we’ll send you a clear quote.
Will you come out to Swinbrook?
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.
How much does sand mastic cost in Swinbrook?
Every job is different, so each one gets its own quote. To get one, phone 0345 464 0079 or email us with a short description of the job.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. We can talk about working times when we quote.
What is sand mastic?
It’s the traditional filler for the joint round timber windows and doors. It combines sand with a linseed-oil-based binder.
Can I add another job to the visit?
Yes. Several rooms, windows or areas can go on one quote.
Are you insured?
Yes. We are fully insured, and we can confirm the details when we quote.
Can old silicone round a sash window be swapped for sand mastic?
Often, yes. Once the silicone is out and the joint prepared we point it with sand mastic.
Why deal with it now?
New mastic over crumbling mastic won’t hold. Raking out and preparing the joint gives it a sound base so the new mastic stays put. Older cottages and farmhouses around Swinbrook can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Combining jobs into one visit generally makes better use of the time than several visits. You’ll get one clear quote for the whole job.

What we do, step by step
Every visit runs the same way: we check the joints, protect the area around them, carry out the job and tidy away. Most jobs take a few hours per window, depending on the condition of the joints. For a village or hamlet like Swinbrook, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We check the window surrounds and agree which joints need renewing.
- Old, loose mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- 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.
How to prepare
- Clear the area around the work
- Where the joints are inside, avoid wetting them before we arrive
- Tell us if parking is tricky

How to look after the new joints
Aftercare is simple:
- Look over the window mastic once a year
- Clear gutters so water does not pour onto the windows
- Avoid patching sand mastic with silicone
- Go gently near the mastic when preparing windows
When preparing windows for paint, take care around the mastic. It can be damaged by heavy scraping.
Fine cracks show the mastic is starting to fail. It’s easier to renew it before it drops out.
When to call us in Swinbrook
Rain on the window surround works into any crack and pushes it out. Windows facing the weather tend to go first.
The problems people normally mention when they call include:
- Old sand mastic that has cracked, crumbled or fallen out
- Wind and rain getting in round a sash window
- Gaps where the frame meets the masonry
- Cement or filler used on old window joints that has cracked
If you look after a building such as Burford School, its window and door frames need their mastic kept sound, just like a home’s.
