Window mastic in Stonecrouch
The mastic around a window or door seals the gap between the frame and the wall. Once that seal fails, wind and rain find the gap. The old mastic is removed and the joint resealed with a flexible exterior sealant. We work on patio & French doors, composite doors and uPVC windows, and common reasons people get in touch are cracked or shrunken mastic around the frame and rain getting in at the frame or under the sill.
Homes in small places like Stonecrouch 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.
There’s a 12-month guarantee on every job, whatever its size.

Leave it or put it right?
Getting a straight, even bead on an outside frame takes practice, especially upstairs. We cut out properly, back deep gaps and tool every joint neatly, using a product chosen for the frame and wall. Where a wall is exposed, as many are in small places like Stonecrouch, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first.
Why choose Mr Mastic in Stonecrouch
- Any old sealant cut out fully, not covered over
- Sealant colour chosen to suit
- An ARBOMaster approved applicator
- Tidy, careful work
Window mastic in Stonecrouch: local notes
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Scotney Castle (about 1.6 miles north-west) are a reminder that the area around Stonecrouch has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
Scotney Castle, about 1.6 miles north-west, is one of the historic houses in the wider area around Stonecrouch, and older homes nearby need a sealant that suits their walls.

Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Wash the frames with mild soapy water
- Make sure the drainage slots aren’t blocked
- Air rooms to keep condensation down around windows
- Keep jet washers away from the mastic
Have a look at the joints once a year, ideally after winter. Cracks and lifting edges are easy to spot early.
Water trapped behind a failed joint can start rot in timber frames and sills. Rotten timber needs a joiner, not a sealant, so it pays to reseal before that happens.

When to call us in Stonecrouch
Plenty of failed mastic was poorly applied in the first place. Sealant run over dust, wet brick or loose mortar didn’t grip properly, and it lets go sooner than it should.
If you can see any of these, it’s time to have the joints looked at:
- A bead that does not match the frame
- Draughty joints inside around the window
- Rain getting in at the frame or under the sill
- Hard, cracked sealant around windows
For landlords with property near Etchingham station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Your questions about window mastic in Stonecrouch
Do you cover smaller places like Stonecrouch?
Yes. Stonecrouch is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you cover Stonecrouch for window mastic?
Yes, Stonecrouch is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job.
Where do you work from?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Will you leave a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
How long before the joint can be used?
It depends on the product. Before we leave, we will tell you the cure time.
Can you do the inside joint as well?
Yes, we do both. Indoors, we seal between the frame and the plaster or reveal, using a paintable sealant if you want to decorate.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done and you’ll get one quote.
Do I have to be there?
It depends on the job. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
How the job changes by surface
Composite doors
Front doors take the weather head on, and the top and bottom corners tend to fail first. We pay most attention there.
Window sills
Sills catch the water running down the glass, so the sill ends and the joint under the frame are vital. Each is cleaned out and resealed.
When it isn’t the sealant
Sealant is not the answer to every problem, and we will tell you before work begins. Sealant will not put right:
- Soft or decayed wood in the frame
- Misting between the panes of a double-glazed unit (that needs a new unit)
- A sash or casement that will not close properly
If in doubt, phone 0345 464 0079 or email us and we’ll say what we think before you book.
Surfaces we seal
- Aluminium frames
- Patio & French doors
- uPVC windows
- Timber windows & doors

DIY sealant or a professional job?
If you’re 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 doesn’t work out, we can still put it right.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
How the visit works
All our tools and materials come with us in the van. Once we have agreed what’s being done, we protect the area and start. It normally takes anything from an hour or two to a full day, depending on how many frames there are. Somewhere like Stonecrouch needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We check each frame and agree which ones need doing.
- The old mastic is cut out and the surfaces cleaned back.
- Deep gaps are filled with backing rod to set the depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- We clear up and check every joint is fully closed.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Let us know about stairs, lifts or work at height
- Let us know about parking restrictions
