About our sand mastic in Letcombe Regis
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 period homes, it looks right where silicone wouldn’t. If you are dealing with gaps where the frame meets the masonry and crumbling sand mastic round a window, we can help, whatever the surface.
Mastic can only go onto a dry, clean joint, so window work in Letcombe Regis is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
Our work is backed for twelve months.

How the visit works
We bring everything the job needs with us, so you don’t need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours for a single window, longer for several. In a small place like Letcombe Regis, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at the surrounds with you and agree the joints to renew.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- Tell us about any water getting in
- Tell us if parking is tricky

Common problems we fix in Letcombe Regis
Water gets into small cracks in the mastic and pushes it out. Exposed elevations generally fail first.
These are the problems we’re asked about most:
- Modern sealant on a period surround
- Gaps round a timber door in stone or brick
- Mastic that needs renewing before redecorating
- Cement or filler used on old window joints that has cracked
For site and facilities teams at buildings such as St Nicholas CofE Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

Leave it or put it right?
Silicone might seem the quicker option, but it can look wrong on a period surround. Sand mastic is the traditional material and blends with the stone or brick. Where a wall is exposed, as many are in small places like Letcombe Regis, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll go through it with you.

Landlord and commercial work in Letcombe Regis
We also work for property managers and facilities teams in Letcombe Regis and across Oxfordshire. Several sites can be quoted together, and we’re fully insured.
Letting agents and landlords in Letcombe Regis can book us as well as homeowners. Sealant work between tenants keeps a property looking cared for.
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
When something else is needed
Before you book, it’s worth knowing the limits too:
- Masonry that needs repairing
- Rotten sashes, sills or window boxes (a joiner’s job)
- Planning or listed building consent (your local planning authority decides)
Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly before booking.

Letcombe Regis homes and the weather
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Homes close to Church of St Andrew include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Your questions about sand mastic in Letcombe Regis
What guarantee comes with sand mastic in Letcombe Regis?
Every job comes with our one-year guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Will you come out to Letcombe Regis?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Where do you work from?
We’re a Crawley-based firm. We work across South East England, London and Scotland.
What exactly is sand mastic?
It’s the traditional filler for the joint round timber windows and doors. It combines sand with a linseed-oil-based binder.
I’m a tenant. Can you help?
Yes. Check with your landlord; we can send the quote to them too.
Does someone need to be in?
We need access to the joints, so we will agree that with you when we book. Indoors, that generally means someone at home.
Can landlords and businesses book you?
Yes, regularly. We can quote for several properties at once.
Do you do commercial work?
Yes. We have worked for hotels, offices and other businesses.
Aftercare tips
A little care helps the new joints last. Our advice:
- Make sure water runs off the sill
- Leave the new mastic unpainted
- Plan mastic work ahead of painting
- Take care around the mastic when scraping paint
Look at the mastic when you look over the windows. Catching cracks early keeps repairs small.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
