About our sand mastic in North Leigh
Across North Leigh, we renew sand mastic around sash and case windows. Each joint is raked out, prepared and pointed by hand, finished to suit the masonry. Typical jobs include gaps round a timber door in stone or brick and silicone on a period window that looks wrong, on tenement windows, period & listed homes and timber door frames.
In a village or hamlet like North Leigh, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
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.

North Leigh homes and the weather
With historic houses such as Blenheim Palace (about 3.9 miles north-east) nearby, there’s older building stock in the area around North Leigh as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For an older house near a landmark such as St Mary's Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Rented homes near Combe station change hands often, and any sash windows need sound mastic to keep draughts and rain out.

The process
Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours per window, depending on the condition of the joints. Somewhere as small as North Leigh, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at the surrounds with you and agree the joints to renew.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Before we arrive
- Try not to wet indoor joints just before the visit
- Tell us about any water getting in
- Move anything stored near the joints

Advice
Landlords, agents and businesses in North Leigh
We work for letting agents and landlords as well as householders. Resealing between tenancies keeps a property looking cared for before the next move-in.
In hotels, rooms out of use cost money, so we plan the work room by room. We have worked in hotels as well as homes and businesses.
What we are called out for in North Leigh
Most of it is simply age. Even well-laid mastic needs renewing in time, depending on exposure and upkeep.
It’s worth asking for a quote if you see:
- Failed mastic on an exposed elevation
- Gaps round a timber door in stone or brick
- Silicone on a period window that looks wrong
- Old cement repairs round a window that have failed
Schools such as North Leigh Church of England (Controlled) School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

Why it’s worth doing now in North Leigh
New sash windows are a major, costly change, and in listed buildings it may need consent. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. Around North Leigh, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Leaving a failed joint normally makes the job bigger, not smaller. If you’re not sure whether it needs doing, call 0345 464 0079 or drop us an email for an honest opinion and a quote.

Questions from North Leigh
Do you cover North Leigh for sand mastic?
Yes, North Leigh is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll send you a clear quote.
Do you cover smaller places like North Leigh?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
When will the new mastic be hard?
The surface skins quite quickly and it hardens fully over a longer time. Timing depends on the weather and the joint.
What do you need from me for a quote?
A short description and the location, with photos by email if possible. If we need more, we’ll ask.
Is there any odour?
Possibly a little. It fades as the sealant cures.
How long does the job take?
Typically it takes a few hours for a single window, longer for several. Bigger jobs take longer, and we’ll say how long yours will take.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
What is sand mastic?
It’s sand mixed with a linseed-oil-based binder, used between timber frames and stone or brick.
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Find out about consent before window work on a listed home
- Do not paint over the new mastic
- Sort the mastic before the decorators arrive
- Take care around the mastic when scraping paint
Make sure water drains away from the window surround. Constant wetting wears the mastic faster.
Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall so early renewal protects both.

DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
