Sand mastic in Royal Tunbridge Wells: local notes
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Groombridge Place (about 3.6 miles west) nearby, there’s older building stock in the area around Royal Tunbridge Wells as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you let a flat or house near Tunbridge Wells station, any sash windows need sound mastic to keep draughts and rain out. Homes close to Parish Church of St Barnabas include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

About our sand mastic in Royal Tunbridge Wells
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s a mix of sand and a linseed-oil-based binder, applied by hand. On period homes, it looks right where silicone wouldn’t. We’re often asked to deal with crumbling sand mastic round a window and gaps where the frame meets the masonry, across stone surrounds, brick reveals and timber door frames.
In a town like Royal Tunbridge Wells, the windows on the most exposed side of a house take the brunt of the rain, and that’s usually where the sealant gives up first. It’s worth looking at every frame, not just the one that leaks.

How it works
The work is kept neat and contained to the area we’re working on, so you can carry on as normal. The job usually takes anything from a few hours to a full day, depending on how many windows, and we explain the cure time before we leave. For a job in Royal Tunbridge Wells, we need access to where the work is and somewhere nearby to park. If the job is outside, mention gates, side access and anything above ground floor.
- First, we look at the surrounds with you and agree what needs doing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- We dress the surface so it sits neatly against the masonry.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Mention if the joints have been sealed before
- Clear the area around the work

When to call us in Royal Tunbridge Wells
Rain on the window surround works into any crack and pushes it out. Windows facing the weather tend to go first.
Keep an eye out for any of the following:
- Old cement repairs round a window that have failed
- Weathered mastic on the most exposed windows
- Mastic round period door frames that has failed
- Mastic dropping out of the joint
Schools such as St Barnabas CofE VA Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

Work for landlords, hotels and businesses
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we’ll quote.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
What affects the cost of sand mastic
Your quote is based on your job. We take into account:
- Working hours on commercial sites
- Any mould that needs treating
- How easy the joints are to reach
- How much there is to do
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
What to tell us for a quote
There’s no need for technical detail. Just tell us:
- Whether it has been sealed before
- Where the job is, and your postcode
- The rough size of the job
- Access, such as stairs, a lift or height
We quote each job on its own, so start by telling us what you need. Simply phone 0345 464 0079 or drop us an email and describe the job.
Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Get any rot dealt with first
- Keep sills and gutters clear so water drains away
- Go gently near the mastic when preparing windows
- Keep modern sealant off the mastic
Check the mastic when you check the paintwork. Small cracks are easier to deal with early.
Sound mastic protects the frame. Failed mastic lets water reach the timber and timber that stays wet can rot.
