About our sand mastic in Lambourn Woodlands
Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant, and we’ll talk through which suits your home. We work on period & listed homes, sash and case windows and brick reveals, and the jobs we see most are open joints round the window box and old sand mastic that has cracked, crumbled or fallen out.
Somewhere as small as Lambourn Woodlands, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.

What affects the cost of sand mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- The product the joint needs
- How easy the joints are to reach
- How many areas need sealing
- How much old sealant there is and how hard it is to remove
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

Your questions about sand mastic in Lambourn Woodlands
Is Lambourn Woodlands within the area you cover?
Yes, Lambourn Woodlands is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
I let a flat near Hungerford station. Can you help?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before we start.
What information do you need?
The location, the problem and the rough size of the job. Photos by email help too.
Do you offer different sealant colours?
In most cases you can choose. We’ll tell you which colours the right product comes in and agree one before work begins.
Can you quote for more than one area?
Yes, we can. Several rooms, windows or areas can go on one quote.
What is sand mastic?
A traditional pointing material made from sand and a linseed-oil-based binder, used between timber frames and stone or brick.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Is sand mastic better than silicone for my windows?
That depends on your windows. On many period windows, sand mastic looks right and suits the building, while modern frames normally get a flexible sealant.
Can I do it myself?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Check with your local planning authority if your home is listed
- Check the mastic when you check the paintwork
- Keep modern sealant off the mastic
- Leave the new mastic unpainted
Leave the new mastic alone while it firms up. It skins over quickly, but takes longer to harden fully.
Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall, so renewing it early is worth it.
When something else is needed
To be straight with you, some problems need a different trade:
- Whether work needs listed building consent
- Sashes that rattle, stick or won’t open
- Putty and glazing repairs
If you are not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer.

Lambourn Woodlands homes and the weather
Historic houses like Ashdown House (about 4.6 miles north-west) are a reminder that the area around Lambourn Woodlands has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.
If you live in an older home near St Mary's Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Advice
What we’re called out for in Lambourn Woodlands
Most of it is simply age. Sand mastic is a maintenance item like any pointing, depending on exposure and upkeep.
Look out for these signs:
- Old cement repairs round a window that have failed
- Gaps where the frame meets the masonry
- A silicone bead on a sash window that spoils the look
- Cracked mastic round a front door frame
Rented homes near Hungerford station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.
