Wartling Sand Mastic
Problem with your window and door surrounds in Wartling? We cut out the old, prepare the joints and apply the right sealant.
- Cement or filler used on old window joints that has cracked
- Weathered mastic on the most exposed windows
- Mastic dropping out of the joint
Why it’s worth doing now in Wartling
Not every draught comes from the sashes themselves. Gaps between the frame and the wall can be just as bad and new mastic seals them. Where a wall is exposed, as many are in small places like Wartling, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

Sand mastic in Wartling
Old sand mastic cracks, crumbles and falls out over time, leaving gaps round the window. We rake it out and renew it and tidies the surround. We work on stone surrounds, period & listed homes and tenement windows, and the jobs we see most are wind and rain getting in round a sash window and mastic worn away on windows facing the weather.
In a village or hamlet like Wartling, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
Your job is guaranteed for a year, as with all our work.

How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Keep modern sealant off the mastic
- Renew mastic before redecorating the windows
- Check the mastic when you check the paintwork
- Find out about consent before window work on a listed home
Avoid painting over the new mastic, which is the traditional advice. Ask us before any decorating around it.
Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.
Wartling homes and the weather
Wartling is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. With historic houses such as Horselunges Manor (about 5 miles west) nearby, there’s older building stock in the area around Wartling as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
In the older streets around The Parish Church of St Mary Magdalene, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Rented homes near Normans Bay station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.

What we do, step by step
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from a few hours to a full day, depending on how many windows. In a small place like Wartling, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each surround and agreeing the joints to renew.
- Old, loose mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic isn’t too thick.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
How to prepare
- Tell us if parking is tricky
- Let us know about earlier repairs to the joints
- Clear items away from the joints we’re working on

Should I try it myself first?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Common questions in Wartling
I let a flat near Normans Bay station. Can you help?
Yes. We work for landlords and letting agents as well as householders, and several properties can be quoted together. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear quote.
Does living near the coast affect sand mastic in Wartling?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Should I try DIY first?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
Where do you work from?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
What is sand mastic?
It’s a mix of sand and a linseed-oil-based binder. It’s built up in the joint by hand and shaped to suit the surround.
How much does sand mastic cost in Wartling?
We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Can old silicone round a sash window be swapped for sand mastic?
In most cases. We remove the silicone and clean the joint, then point it with sand mastic.
Is there any odour?
It depends on the product. Some smell for a while, some hardly at all.
