What affects the cost of sand mastic
The quote reflects the job in front of us. We look at:
- Whether there’s mould to deal with
- Whether old sealant or filler has to be cut out
- The number and length of the joints
- The product the joint needs
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, phone 0345 464 0079 or send us an email for an honest opinion and a quote.

Sand mastic for homes and businesses in Laddingford
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, applied by hand. On older homes, it suits the building far better than silicone. We work on tenement windows, stone surrounds and timber door frames, and people most often call us about draughts and rain around sash boxes and window mastic to renew ahead of painting.
Homes in small places like Laddingford often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Why deal with it now?
Not every draught comes from the sashes themselves. Open mastic joints round the box can let air in and new mastic seals them. In a small place like Laddingford, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
The cost depends on how much there is to do, how much old material has to come out and access to the work. We give a clear quote before any work starts, so you know where you stand.
Why choose Mr Mastic in Laddingford

From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.

Laddingford homes and the weather
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

Your questions about sand mastic in Laddingford
Will you come out to Laddingford?
Yes, Laddingford 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.
Can you do sand mastic in Laddingford?
Yes. We work across London and the South East, and Laddingford is part of that. Just phone 0345 464 0079 or drop us an email with a few details of the job, and we’ll send you a clear quote.
Do I need permission for sand mastic on a listed building?
Your local planning authority is the one to ask. They decide whether consent is needed for work to your windows.
Do I need to be at home?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
How long does sand mastic take to go off?
It takes a while. It skins first and hardens fully later, and we will tell you what to expect.
Can I do it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Do you hold any approvals?
Yes. We are an ARBOMaster approved applicator, which is run for the Arbo sealant brand.

When it is not the sealant
New sealant cannot fix everything, and we’d rather say so up front. Sealant won’t put right:
- Sash cords, weights and draught-proofing of the sashes
- Masonry that needs repairing
- Decayed frames that need repair
If you’re not sure, just call 0345 464 0079 or email us and we will give you a straight answer before you book.
Surfaces we seal
- Timber door frames
- Sash and case windows
- Period & listed homes
- Brick reveals
- Tenement windows
- Stone surrounds
Do you need sand mastic in Laddingford?
Over the years, sand mastic weathers. It dries out, cracks and loses its grip from the frame or the masonry.
Common reasons people contact us include:
- Wind and rain getting in round a sash window
- Silicone on a period window that looks wrong
- Tired mastic found when preparing windows for paint
- Mastic dropping out of the joint
If you live in an older home near St Mary, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
