How we handle sand mastic in Bobbingworth
Traditional burnt sand mastic blends with stone and brick surrounds. It’s a good fit for period properties where a modern sealant bead would stand out. If you are dealing with failed mastic on an exposed elevation and draughty sash windows at the surround, we can put it right, on period & listed homes, sash and case windows and timber door frames alike.
Mastic can only go onto a dry, clean joint, so window work in Bobbingworth is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
Each job carries a 12-month guarantee, whatever its size.

What we’re called out for in Bobbingworth
Shallow joints are a common cause. Mastic that is too thin cracks and drops out, which is why we pack deep voids first and get the depth right.
These are the problems we’re asked about most:
- Draughts and rain around sash boxes
- Mastic worn away on windows facing the weather
- Gaps round a timber door in stone or brick
- Window mastic to renew ahead of painting
If you look after a building such as Moreton Church of England Voluntary Aided Primary School, its window and door frames need their mastic kept sound, just like a home’s.

Sand mastic in Bobbingworth: local notes
Historic houses like Hill Hall (about 4.9 miles south-west) are a reminder that the area around Bobbingworth 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. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In the older streets around Church of St Germain, 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 Bobbingworth
Is there a guarantee on sand mastic in Bobbingworth?
Every job comes with our 12-month guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Is Bobbingworth within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is it possible to take out silicone and use sand mastic instead?
In most cases. The silicone is cut out and the joint cleaned, then point it with sand mastic.
Can I choose the sealant colour?
Most of the time, yes. We’ll explain which colours are available.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status and we are fully insured too.
Can you seal over the old sealant?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
How long does sand mastic take to go off?
The surface skins quite quickly and it hardens fully over a longer time. Timing depends on the weather and the joint.
Do you work for hotels and businesses?
Yes. We work in offices, washrooms, hotels and other commercial premises. We can talk about working times when we quote.
How we quote for sand mastic
You’ll get a clear quote before any work starts. It takes into account:
- The amount of work
- How many rooms, windows or areas are involved
- Working hours on commercial sites
- Mould in or behind the old joints
What you pay reflects the work, not guesswork. That’s why we ask a few questions first.
What we need to know
Photos by email are helpful but not essential. Try to tell us:
- Where the property is
- Pictures of the joints, sent by email
- The type of property
- If someone has resealed it before
We quote each job on its own, so start by telling us what you need. Simply phone 0345 464 0079 or send us an email and describe the job, and pictures are welcome.
What happens if it’s left?
New sash windows are a major, costly change and on a listed home, consent may be needed. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. Older cottages and farmhouses around Bobbingworth can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs. Call for a quick quote and we will explain what it covers.
Why us?
- Anti-fungal sanitary silicone in wet areas
- Domestic, commercial and hotel work

How the job changes by surface
Sash and case windows
Most of our sand mastic work is on sash windows. We renew the mastic round each box.
Timber door frames
Round a period front door, sand mastic gives the right look.
How to look after the new joints
So the new joints stay in good condition:
- Clear gutters so water does not pour onto the windows
- Avoid patching sand mastic with silicone
- Avoid heavy scraping on the mastic joint
- Have rotten timber repaired before new mastic goes in
Look at the mastic when you look over the windows. Small cracks are easier to deal with early.
Fine cracks show the mastic is starting to fail. It’s easier to renew it before it drops out.
What happens on the day
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours per window, depending on the condition of the joints and we leave things clean and tidy. In a small place like Bobbingworth, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- Large voids are packed out.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Plan for the work area to be out of bounds to pets and children
- For business premises, tell us about site rules or sign-in
