Hobbs Cross Sand Mastic
Sand mastic across Hobbs Cross and nearby, with old sealant always removed completely and a 12-month guarantee.
- Gaps between timber frames and stone or brick
- Mastic dropping out of the joint
- Cement or filler used on old window joints that has cracked
Should I try it myself first?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
Sand mastic for homes and businesses in Hobbs Cross
Sand mastic has long been used to fill the joint between timber frames and masonry. 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 have cement or filler used on old window joints that has cracked and window mastic to renew ahead of painting, we can help.
Homes in small places like Hobbs Cross 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.
The work is covered for a year after we finish. If anything isn’t right with it, call 0345 464 0079 or email us.

What we’re called out for in Hobbs Cross
Shallow joints are a common cause. A thin layer doesn’t hold well so we make sure the new mastic is the right thickness.
Keep an eye out for these signs:
- Gaps where the frame meets the masonry
- Failed mastic on an exposed elevation
- Tired mastic found when preparing windows for paint
- Mastic round period door frames that has failed
If you look after a building such as St John's Church of England Voluntary Controlled School, its window and door frames need their mastic kept sound, just like a home’s.

FAQs for Hobbs Cross
Is Hobbs Cross within the area you cover?
Yes. Hobbs Cross is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is there a guarantee on sand mastic in Hobbs Cross?
Every job comes with our one-year guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
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.
What sealant do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll explain our choice.
Can I do it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
Is there any odour?
There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.
Do you offer different sealant colours?
Normally, yes. White, clear and grey are common, and other colours are available for many products, and we agree the colour with you before any work starts.
What exactly is sand mastic?
It’s a mix of sand and a linseed-oil-based binder. It’s built up in the joint by hand and finished to sit neatly against the masonry.

What sand mastic looks like in Hobbs Cross
Rainfall in the South East is lower than in much 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 Hill Hall (about 0.9 miles east) nearby, there’s older building stock in the area around Hobbs Cross as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Homes close to Church of All Saints include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

- First, we look at the surrounds with you and agree what needs doing.
- Old, loose mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
