Sand mastic in Stratton Audley, done properly
On many period windows, sand mastic looks right and suits the building. Newer frames usually get a flexible sealant instead, and we’ll talk through which suits your home. Typical jobs include open joints round the window box and modern sealant on a period surround, on tenement windows, timber door frames and brick reveals.
Mastic can only go onto a dry, clean joint, so window work in Stratton Audley is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
Every job is covered by our 12-month guarantee, wherever you are in Oxfordshire.

Stratton Audley questions
Can you do sand mastic in Stratton Audley?

What should I tell you?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply ring 0345 464 0079 or email us.
Can you match the sealant colour?
Yes. White, clear and grey are common, and other colours are available, and we agree the colour with you before work begins.
Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.
Do you work for hotels and businesses?
Yes. We’ve worked for hotels, offices and other businesses and we’re fully insured.
Can you seal over the old sealant?
No. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Is there any odour?
There can be a smell while the sealant cures. Opening a window helps.
Do you need sand mastic in Stratton Audley?
Timber frames move with the seasons. That movement opens up the mastic joint little by little.
Signs it’s time to call us include:
- Open joints round the window box
- Old sand mastic that has cracked, crumbled or fallen out
- Cracked mastic round a front door frame
- Old cement repairs round a window that have failed
Homes close to Church of St Mary and St Edburga include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in.

Leave it or put it right?
Draughts round a sash window are not always the sashes. Open mastic joints round the box can let air in, and renewing the mastic closes them. Older cottages and farmhouses around Stratton Audley can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or send us an email and we’ll talk you through it.

DIY sealant or a professional job?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.

Looking after it afterwards
A little care helps the new joints last. We recommend:
- Check the mastic when you check the paintwork
- Have rotten timber repaired before new mastic goes in
- Do not run silicone over sand mastic
- Leave the new mastic unpainted
Avoid painting over the new mastic, which is the traditional advice. If you are redecorating, ask us first.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
