About our window mastic in Stone
From a single sill to a whole house of windows, the work is priced before anything is done. To get one, call 0345 464 0079 or email us with the number of frames and any access details for window mastic in Stone. Typical jobs include gaps left after new windows were fitted and white mastic on grey or black frames, on window sills, uPVC windows and composite doors.
Homes in small places like Stone 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.
A 12-month guarantee comes as standard, so you’re covered after we’ve gone.

Stone questions
Is Stone within the area you cover?
Yes, Stone is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Does the coastal weather in Stone affect outside sealant?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
I rent my home. Can I book you?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.
Should I try DIY first?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Can you reach windows above the ground floor?
Normally, yes. We plan safe access before the job.
Where do you work from?
We’re a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Are you ARBOMaster approved?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Is there any odour?
It depends on the product. Some products have a noticeable smell, others very little.
Why deal with it now?
Running fresh sealant over the old joint is tempting, but new sealant can’t bond to old, crumbling mastic. It soon lifts and the leak carries on behind it. Proper resealing starts with removing the old joint. Around Stone, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are unsure, call 0345 464 0079 or email us for an honest opinion and a quote.

Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Keep paint and stain on wooden frames in good order
- Look round the frames every year or so
- Wipe condensation off the frames
- Keep drainage slots and sill grooves clear
A yearly look round the frames is enough. Small splits are simple to catch before they leak.
Water trapped behind a failed joint can start rot in timber frames and sills. Once wood has rotted, it needs repair before it can be sealed, so early resealing is worth it.
Honest limits
Before booking, it’s worth knowing the limits too:
- Rotten timber, which needs a joiner first
- Penetrating damp from a failed cavity tray or render
- Worn gaskets, brush seals or a door that has dropped
If you’re not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer.

What else we do in Stone
How the visit works
When we arrive, we start by going over the job with you, so you know exactly what we’re doing. Surfaces next to the work are protected before we start. Most jobs take a few hours for a handful of frames, longer for a whole house. Somewhere like Stone needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Mention if the joints have been sealed before
- On commercial sites, let us know about site rules
How to get a quote

Related advice
What the job involves on each surface
Composite doors
If the door itself is draughty, the issue may be the door seals or hinges rather than the frame mastic. We will tell you if that is what we find.
Patio & French doors
The joints around patio doors run a long way, top, sides and threshold. Most leaks start at the bottom corners, so we pay close attention there.
What window mastic looks like in Stone
Stone is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around window and door frames, especially on the side facing the sea. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For an older house near a landmark such as St Francis, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Around Stone, as everywhere, window mastic is only as good as the preparation behind it.

DIY versus a professional finish
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
