Any of these means the joints need attention:
- Failed mastic on an exposed elevation
- Gaps where the frame meets the masonry
- Patchy fillers round a sash window
- Tired mastic found when preparing windows for paint

How we handle sand mastic in Shepperton Green
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s made from sand and a linseed-oil-based binder and built up by hand. On older homes, it suits the building far better than silicone. We’re often asked to deal with gaps between timber frames and stone or brick and failed mastic on an exposed elevation, across tenement windows, brick reveals and stone surrounds.
In smaller places like Shepperton Green, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. The right sealant depends on the frame and on what it sits in.
Every job comes with a 12-month guarantee, wherever you are in Surrey.

Shepperton Green: your questions answered
I let a flat near Shepperton station. Can you help?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or email us with the details for a clear quote.
Do you cover smaller places like Shepperton Green?
Yes. Shepperton Green 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.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will tell you what we’re using.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Do you hold any approvals?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Do I need to be at home?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Will there be a smell?
There can be a smell while the sealant cures, but it fades. Opening a window helps.
Is consent needed for window work on a listed home?
Checking first is sensible. Ask your local planning authority whether consent is needed for work on a listed home or in a conservation area.
Can I do it myself?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
How the visit works
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours for a single window, longer for several. Parking around Shepperton Green is usually easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic isn’t too thick.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
Before we arrive
- Mention any parking rules near the property
- Mention any sign-in or site rules at work premises
- Plan for the work area to be out of bounds to pets and children

Windows and doors in Shepperton Green
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Botleys Mansion (about 3.6 miles south-west) nearby, there’s older building stock in the area around Shepperton Green 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.
If you look after a building such as Saxon Primary School, larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around Church of St Mary Magdalene, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Leave it or put it right?
If you’re redecorating, renew the mastic first. Paint over cracked mastic won’t stop the gaps and traditional guidance is to leave the new mastic unpainted. Homes in smaller places like Shepperton Green can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Ask us for a quote and we will explain what it covers.
