About our sand mastic in Dane Hill
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s a mix of sand and a linseed-oil-based binder and built up by hand. On older homes, it suits the building far better than silicone. If you have silicone on a period window that looks wrong and gaps between timber frames and stone or brick, we can help, on timber door frames, brick reveals and sash and case windows alike.
In a village or hamlet like Dane Hill, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

How the visit works
You do not need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the job takes a few hours per window, depending on the condition of the joints for a typical job. In a small place like Dane Hill, access is generally 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.
- We rake out the old mastic and clean the joint.
- 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 mastic is finished to sit tidily against the stone or brick.
Before we arrive
- On commercial sites, let us know about site rules
- Let us know about parking restrictions
- Tell us about any water getting in

Dane Hill questions
Will you come out to Dane Hill?
Yes, Dane Hill is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
I let a flat near Heyford station. Can you help?
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.
What information do you need?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply call 0345 464 0079 or send us an email.
What does sand mastic cost?
It depends on the job, so we quote each one individually. For a quick quote, call 0345 464 0079 or send us an email with a short description of the job.
Where do you work from?
We work from Crawley. We cover Dane Hill and the rest of Oxfordshire, along with the rest of our area.
Which is right for my windows, sand mastic or modern sealant?
It depends on the window. Period windows in stone or brick usually suit sand mastic, while modern frames normally get a flexible sealant.
Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in.
Will it make a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
What sand mastic looks like in Dane Hill
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.
Rented homes near Heyford station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.
