About our sand mastic in Rowledge
Burnt sand mastic is a traditional material that sits naturally against stone and brick. It suits period and listed homes where a modern sealant bead would stand out. We work on stone surrounds, period & listed homes and tenement windows, and common reasons people get in touch are mastic that needs renewing before redecorating and crumbling sand mastic round a window.
Homes in small places like Rowledge often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
Whatever the size of the job, you get the same one-year guarantee.

Frames and glazing around Rowledge
With historic houses such as Farnham Castle (about 2.6 miles north) nearby, there’s older building stock in the area around Rowledge as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.
Homes close to Saint James include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For landlords with property near Bentley (Hampshire) station, any sash windows need sound mastic to keep draughts and rain out. Schools such as Rowledge Church of England Controlled Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

How to look after the new joints
To keep the joints looking good and working properly:
- Ask us before painting near the mastic
- Make sure water runs off the sill
- Get any rot dealt with first
- Check with your local planning authority if your home is listed
Look at the mastic when you look over the windows. Catching cracks early keeps repairs small.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens.
How the job changes by surface
Period and listed homes
On a listed home or in a conservation area, the right material matters. Like-for-like sand mastic is generally favoured.
Sash and case windows
The box of a sash and case window sits in the stone or brick opening. The gap round it is pointed with sand mastic.

Advice
Rowledge questions
Is Rowledge in your area for sand mastic?
Yes, Rowledge is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or drop us an email and let us know what needs doing.
Is Rowledge within the area you cover?
Yes, Rowledge is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Where are you based?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
Is it possible to take out silicone and use sand mastic instead?
Yes. The silicone is cut out and the joint cleaned, then point it with sand mastic.
Do I have to be there?
It depends on the job. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.
Which is right for my windows, sand mastic or modern sealant?
That depends on your windows. Period windows in stone or brick usually suit sand mastic and newer frames normally get a flexible sealant.
How long does sand mastic take to harden?
It takes a while. It skins first and hardens fully later and we will give you an idea for your job.
Will you leave a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Why deal with it now?
New sash windows are a major, costly change and on a listed home, consent may be needed. Where the frames are in good order, new mastic seals the surround. Around Rowledge, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

How we quote for sand mastic
There’s no set price list, because jobs vary so much. What we look at:
- Whether old sealant or filler has to be cut out
- Mould in or behind the old joints
- Whether the work is at height
- The number and length of the joints
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
Asking for a quote
Before you ask for a quote, have a think about:
- Whether it’s a home or a business
- Where the job is, and your postcode
- Roughly how big the job is
- What’s wrong with the joints now
