How we handle sand mastic in Inhurst
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s made from sand and a linseed-oil-based binder, applied by hand. On period homes, it looks right where silicone wouldn’t. We work on brick reveals, sash and case windows and tenement windows, and the jobs we see most are draughts and rain around sash boxes and window mastic to renew ahead of painting.
Homes in small places like Inhurst 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.
There’s a 12-month guarantee on every job, large or small.

The process
When we arrive, we start by going over the job with you. Surfaces next to the work are protected before we start. Most jobs take a few hours for a single window, longer for several. Somewhere as small as Inhurst, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each surround is checked first.
- We rake out the old mastic and clean the joint.
- Large voids are packed out.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
Before we arrive
- Let us know about earlier repairs to the joints
- Mention any sign-in or site rules at work premises
- Clear items away from the joints we are working on

What affects the quote in Inhurst
The quote reflects the job in front of us. We take into account:
- Whether old sealant or filler has to be cut out
- How many rooms, windows or areas are involved
- Any mould that needs treating
- The number and length of the joints
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
Helping us quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- Whether it’s a home or a business
- If someone has resealed it before
- Roughly how big the job is
- What the problem is, such as mould, gaps, leaks or cracking
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we will explain how we’d tackle it. When it suits you, call 0345 464 0079 or drop us an email.
How to look after the new joints
Aftercare is simple:
- Have rotten timber repaired before new mastic goes in
- Look over the window mastic once a year
- Do not run silicone over sand mastic
- Sort the mastic before the decorators arrive
Keep gutters and sills clear so water runs away from the surround. Water sitting against the mastic shortens its life.
Sound mastic protects the frame. Failed mastic lets water reach the timber and timber that stays wet can rot.
What sealant work cannot fix
To be straight with you, some problems need a different trade:
- Sash cords, weights and draught-proofing of the sashes
- Crumbling stone or brickwork round the window
- Rotten sashes, sills or window boxes (a joiner’s job)
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we will tell you honestly before booking.

What happens if it’s left?
Filling over old, loose mastic doesn’t last. We remove the loose material first so the new mastic stays put. Where a wall is exposed, as many are in small places like Inhurst, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first.

Inhurst: your questions answered
Is Inhurst in your area for sand mastic?
Yes, Inhurst is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll give you a clear quote.
Do you work for landlords with property near Midgham station?

What sealant do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We’ll tell you what we’re using and why.
Is it worth trying it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
How long does sand mastic take to go off?
It forms a skin fairly soon and it hardens fully over a longer time. The weather and joint depth both affect it.
Can I choose the sealant colour?
We help you choose a colour that suits, from white and clear to greys and other shades. The choice depends on the product the joint needs.
Can I add another job to the visit?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Will the old sealant be removed?
Yes, every time. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Common problems we fix in Inhurst
Shallow joints are a common cause. Mastic that’s too thin cracks and drops out, which is why we pack deep voids first and get the depth right.
It’s worth asking for a quote if you see:
- Tired mastic found when preparing windows for paint
- Gaps between timber frames and stone or brick
- Draughts and rain around sash boxes
- Modern sealant on a period surround
If you look after a building such as The Hurst School, the mastic around its windows and doors needs looking after like any other building’s.
