Sand Mastic in Balscote
Professional sand mastic in and around Balscote, with every bit of old sealant taken out first.
- Wind and rain getting in round a sash window
- Gaps between timber frames and stone or brick
- Gaps round a timber door in stone or brick
Different surfaces, different methods
Sash and case windows

Timber door frames
Round a period front door, sand mastic gives the right look.
Sand mastic in Balscote, done properly
On many period windows, sand mastic looks right and suits the building. Newer frames normally get a flexible sealant instead and we’ll explain which is best for yours. If you’re dealing with weathered mastic on the most exposed windows and crumbling sand mastic round a window, we can help, whatever the surface.
Around Balscote, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.

How it works
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. It normally takes anything from a few hours to a full day, depending on how many windows. Somewhere like Balscote needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First, we look at the surrounds with you and agree what needs doing.
- Old, loose mastic is raked out and the joint cleaned.
- 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.
Getting ready for the visit

Leave it or put it right?
Replacing sash windows is a big decision for a period home and on a listed home, consent may be needed. Where the frames are in good order, new mastic seals the surround. In a small place like Balscote, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Combining jobs into one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll send you a clear quote for the lot.

Balscote homes and the weather
With historic houses such as Upton House (about 2.8 miles north-west) nearby, there’s older building stock in the area around Balscote as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you let a flat or house near Banbury station, any sash windows need sound mastic to keep draughts and rain out. If you live in an older home near Church of St Mary Magdalene, the joint between an old wall and a newer frame is generally the first place rain gets in.

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Clear gutters so water doesn’t pour onto the windows
- Check the mastic when you check the paintwork
- Check with your local planning authority if your home is listed
- Have rotten timber repaired before new mastic goes in
Avoid painting over the new mastic, as traditional guidance advises. If you are redecorating, ask us first.
Renewing mastic before redecorating saves doing it twice. Painting over failed mastic hides the problem for a while.

Questions from Balscote
Do you work for landlords with property near Banbury station?
Yes, we work for landlords and letting agents. Just call 0345 464 0079 or drop us an email and tell us about the property, and we will send you a clear quote.
Do you cover Balscote for sand mastic?
Yes. Our work covers London and the South East, and Balscote is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will tell you what we’re using.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
Can old silicone round a sash window be swapped for sand mastic?
In most cases. The silicone is cut out and the joint cleaned, then point it with sand mastic.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status.
Are you fully insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Is it OK to seal over old sealant?
No, because it fails. The old sealant always comes out first, so the new joint bonds to clean surfaces.

DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
