Hurley Sand Mastic
Our applicators work in Hurley on traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old material cut out, joints cleaned and sealed neatly.
- Old cement repairs round a window that have failed
- Draughty sash windows at the surround
- Cracked mastic round a front door frame
What happens if it’s left?
Not every draught comes from the sashes themselves. Open mastic joints round the box can let air in, and renewing the mastic closes them. In a small place like Hurley, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll explain what it covers.

About our sand mastic in Hurley
Sand mastic does not last for ever and gaps open up round the frame. We rake it out and renew it so the surround looks right again. We are often asked to deal with old cement repairs round a window that have failed and mastic dropping out of the joint, across brick reveals, sash and case windows and period & listed homes.
Around Hurley, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
There’s a 12-month guarantee on every job.

How it works
Every visit runs the same way: we check the joints, protect the area around them, do the work and clear up. Most jobs take a few hours per window, depending on the condition of the joints. For a village or hamlet like Hurley, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- Each surround is checked first.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic is not too thick.
- We point the joint with sand mastic by hand.
- We finish the mastic to a tidy line.
How to prepare
- Clear items away from the joints we are working on
- Keep children and pets away from the work area
- Where the joints are inside, avoid wetting them before we arrive

Advice
What we’re called out for in Hurley
Previous repairs in cement or silicone often trap water or crack away. They don’t move with the timber, and they usually need raking out.
Keep an eye out for any of the following:
- Tired mastic found when preparing windows for paint
- Gaps where the frame meets the masonry
- Failed mastic on an exposed elevation
- A silicone bead on a sash window that spoils the look
For site and facilities teams at buildings such as Danesfield School, its window and door frames need their mastic kept sound, just like a home’s.

Can you help a landlord with a rental near Marlow station?

Is Hurley in your area for sand mastic?
Yes. Our work covers London and the South East, and Hurley is part of that. Just ring 0345 464 0079 or email us with a few details of the job.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Where is Mr Mastic based?
We are a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
Do you offer different sealant colours?
We help you choose a colour that suits. The choice depends on the product the joint needs.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Which is right for my windows, sand mastic or modern sealant?
That depends on your windows. Period windows in stone or brick normally suit sand mastic, while modern frames normally get a flexible sealant.
Are you an approved applicator?
Yes. We are an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What sand mastic looks like in Hurley
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. Historic houses like Harleyford Manor (about 0.6 miles north) are a reminder that the area around Hurley has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
For an older house near a landmark such as Church of St Mary, frames set in older brick or stone need a sealant that suits the wall as well as the frame. If you let a flat or house near Marlow station, any sash windows need sound mastic to keep draughts and rain out.

Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Find out about consent before window work on a listed home
- Avoid heavy scraping on the mastic joint
- Renew mastic before redecorating the windows
- Don’t run silicone over sand mastic
Make sure water drains away from the window surround. Constant wetting wears the mastic faster.
Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall, so renewing it early is worth it.
How we quote for sand mastic
The quote reflects the job in front of us. We look at:
- When we can work, for business premises
- Whether there’s mould to deal with
- Access and height
- Which sealant suits the joint
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
Asking for a quote
To help us quote quickly, let us know:
- Roughly how big the job is

Different surfaces, different methods
Stone surrounds
Sand mastic sits naturally against stone. The finish blends with the masonry.
Period and listed homes
Many older homes were built with sand mastic round the windows. If your home is listed, ask your local planning authority about consent.
