Sand mastic for homes and businesses in Enstone
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s made from sand and a linseed-oil-based binder and built up by hand. On period homes, it looks right where silicone wouldn’t. If you’re dealing with open joints round the window box and wind and rain getting in round a sash window, we can help.
Mastic can only go onto a dry, clean joint, so window work in Enstone is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
A one-year guarantee comes as standard, so you’re not left on your own once the job is done.

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.

Advice
Quotes for sand mastic in Enstone
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Working hours on commercial sites

- The problem you’ve noticed
- Whether it’s a home or a business

Enstone questions
Is Enstone within the area you cover?
Yes, Enstone is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Charlbury station?
Yes, we work for letting agents and landlords. You can phone 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before any work starts.
Is sand mastic better than silicone for my windows?
For period timber windows in stone or brick, sand mastic is often the better fit. Modern frames normally suit a flexible sealant.
Can you work on commercial sites?
Yes. We can plan bigger jobs in stages.
How long does sand mastic take to harden?
It takes a while. It skins first and hardens fully later, and we’ll tell you what to expect.
How do I get a quote for sand mastic in Enstone?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before work begins.
Do I need permission for sand mastic on a listed building?
Speak to your local planning authority before work starts. Sand mastic is often favoured as like for like, but they decide.
Will you leave a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Do you need sand mastic in Enstone?
Decorating can disturb tired mastic. Many people find it crumbling when they prepare the windows.
Any of these means the joints need attention:
- Modern sealant on a period surround
- Open joints round the window box
- Failed mastic on an exposed elevation
- Mastic dropping out of the joint
Homes close to Church of St Kenelm include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in.
What to look for in a quote
- Is the old sealant removed completely?
- How the joint is cleaned and prepared
- What the quote includes, VAT included or not
- How long the guarantee is
For landlords and businesses
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
We also work for property managers and facilities teams in Enstone and across Oxfordshire. We can quote a run of properties together, and we are fully insured.
