Sand mastic for homes and businesses in Wadhurst
Traditional burnt sand mastic blends with stone and brick surrounds. It suits period and listed homes where a modern sealant bead would stand out. If you have gaps where the frame meets the masonry and weathered mastic on the most exposed windows, we can put it right, whatever the surface.
Around Wadhurst, conservatories, garden rooms and patio doors are often part of the house. Their glazing joints and frame seals are as much a part of the job as the windows.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or drop us an email.

What sand mastic looks like in Wadhurst
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Wadhurst Castle (about 0.1 miles south) are a reminder that the area around Wadhurst has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
For landlords with property near Wadhurst station, cracked sand mastic around sash windows lets in the draughts tenants complain about. Homes close to The Parish Church of St Peter and St Paul include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Aftercare tips
How long the joints last depends on use and care. We suggest:
- Look over the window mastic once a year
- Find out about consent before window work on a listed home
- Have rotten timber repaired before new mastic goes in
- Do not paint over the new mastic
Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.
Renewing mastic before redecorating saves doing it twice. Painting over failed mastic hides the problem for a while.

Leave it or put it right?
Not every filler suits an old window surround. Sand mastic is the like-for-like choice and that can be important for listed homes. In an older home around Wadhurst, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.

Wadhurst questions
Do you cover smaller places like Wadhurst?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
I let a flat near Wadhurst station. Can you help?
Yes, we work for letting agents and landlords. Just ring 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear quote.
Where do you work from?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
How long does sand mastic take to go off?
It takes a while. It skins first and hardens fully later, and we’ll tell you what to expect.
Do I have to be there?
That depends on where the joints are. For work indoors, someone needs to let us in.
Can you seal over the old sealant?
No, it will not last. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Can old silicone round a sash window be swapped for sand mastic?
Yes, it’s a common request. The old silicone has to come out completely so the mastic can sit properly.
What exactly is sand mastic?
Sand mastic is a traditional material for pointing round windows and doors. It’s made with sand and a linseed-oil-based binder.
The process
A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and tidy away. Most jobs take a few hours per window, depending on the condition of the joints. Parking around Wadhurst is usually easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- First, we look at the surrounds with you and agree what needs doing.
- We rake out the old mastic and clean the joint.
- Large voids are packed out first, so the mastic is not too thick.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Getting ready for the visit
- Mention any tricky access
- Mention any leaks or damp you’ve noticed
- Tell us about any previous sealing or DIY attempts

Advice
DIY sealant or a professional job?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
What we cannot put right
In fairness, some problems need a different trade:
- Decisions on consent for listed homes
- Cracked or broken glass
- Decayed frames that need repair
If you’re not sure, just call 0345 464 0079 or drop us an email and we will give you a straight answer before you book.
Surfaces we seal
- Timber door frames
- Stone surrounds
- Tenement windows
- Period & listed homes
- Brick reveals
- Sash and case windows
When to call us in Wadhurst
Decorating can disturb tired mastic. Many people find it crumbling when they prepare the windows.
The problems people normally mention when they call are:
- Gaps where the frame meets the masonry
- Draughts and rain around sash boxes
- Old cement repairs round a window that have failed
- Modern sealant on a period surround
Schools such as Wadhurst CofE Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
