Leave it or put it right?
Draughts round a sash window aren’t always the sashes. Gaps between the frame and the wall can be just as bad, and renewing the mastic closes them. Around Warnford, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
The cost depends on how much there is to do, how much old material has to come out and access to the work. You will have a clear quote before any work starts.

Sand mastic for homes and businesses in Warnford
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. 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 are dealing with draughty sash windows at the surround and old sand mastic that has cracked, crumbled or fallen out, we can help, on stone surrounds, period & listed homes and brick reveals alike.
Mastic can only go onto a dry, clean joint, so window work in Warnford is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or email us.

What affects the quote in Warnford
Some jobs are bigger than they look, and some smaller. The main factors:
- Any working-time requirements on site
- How much old sealant there is and how hard it is to remove
- Whether the work is at height
- The number of rooms or windows
Combining jobs into one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.
What to tell us for a quote
What to tell us when you ask for a quote:

Warnford questions
Do you cover smaller places like Warnford?
Yes, we do. 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.
Is sand mastic in Warnford guaranteed?
All our work, in Warnford and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Can you quote for more than one area?
Yes. Several rooms, windows or areas can go on one quote.
What exactly is sand mastic?
A traditional pointing material made from sand and a linseed-oil-based binder for the joint between timber frames and masonry.
How much does sand mastic cost in Warnford?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
What should I tell you?
A short description and the location. If we need more, we’ll ask.
Will there be a smell?
Sometimes, a little. It fades as the sealant cures.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
What sand mastic looks like in Warnford
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Hinton Ampner House (about 3.1 miles north-west) nearby, there’s older building stock in the area around Warnford as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
In and around Warnford, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

What happens on the day
We bring everything the job needs with us, so you don’t need to buy or prepare anything. Once we have agreed what’s being done, we protect the area and start. It normally takes anything from a few hours to a full day, depending on how many windows. Somewhere as small as Warnford, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check each window surround and the condition of the joint.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic is not too thick.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.
Getting ready for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us if parking is tricky
- Keep children and pets away from the work area

When to call us in Warnford
Over the years, sand mastic weathers. It hardens, cracks and starts to come away on the stone or timber.
Most people get in touch after spotting something like this:
- Mastic round period door frames that has failed
- Old cement repairs round a window that have failed
- A silicone bead on a sash window that spoils the look
- Old sand mastic that has cracked, crumbled or fallen out
If you live in an older home near Church of Our Lady, the joint between an old wall and a newer frame is usually the first place rain gets in.
