- Rushed sealant from a window installation
- Leaking joints at the ends of sills
- Sealant in the wrong colour for the frame
Looking after it afterwards
Aftercare is simple:
- Avoid harsh chemicals near the mastic
- Don’t aim a pressure washer at the joints
- Ventilate rooms so frames do not stay wet inside
- Paint up to the joint, not over it
Wipe the frames with soapy water when you clean the windows, and avoid solvent cleaners on the sealant.
A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. Resealing closes it.
Window mastic for homes and businesses in Palmer's Green
A window frame and the wall around it expand and shrink at different rates. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. That’s why the joint needs a flexible, low-modulus sealant rather than something rigid. Typical jobs include draughty joints inside around the window and whistling draughts around closed windows, across aluminium frames, patio & French doors and window sills.
Homes in small places like Palmer's Green often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Windows and doors in Palmer's Green
The South East is one of 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 Scotney Castle (about 4 miles south) are a reminder that the area around Palmer's Green 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’s traditional sand mastic.
Schools such as Brenchley and Matfield Church of England Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. If you live in an older home near Parish Church of All Saints, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

When to call us in Palmer's Green
Every frame moves through the day. Sun on a frame makes it expand, and it contracts again overnight, while the brick or render around it hardly moves. If the sealant cannot stretch, it splits.
These are the problems we are asked about most:
- Black, perished sealant on frames
- Leaking joints at the ends of sills
- Damp patches on the reveal after heavy rain
- Draughts coming in around windows and doors
Rented homes near Paddock Wood station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

What we do, step by step
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take a morning for a couple of windows and a door. For a village or hamlet like Palmer's Green, the journey is planned in advance: 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.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
How to prepare
- Let us know about earlier repairs to the joints
- Tell us if parking is tricky
- Mention any leaks or damp you’ve noticed

Palmer's Green questions
I let a flat near Paddock Wood station. Can you help?
Yes. We work for letting agents and landlords as well as homeowners. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Do you cover Palmer's Green for window mastic?
Yes, Palmer's Green is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear quote.
Are you insured?
Yes. We’re fully insured, and we can confirm the details when we quote.
Can you do several jobs on one visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
Can resealing stop a draught around my window?
If the draught is coming in around the frame, yes. If it’s through the window’s own seals or a hinge, that’s a different fix, and we will say so.
Where is Mr Mastic based?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
When is the sealant fully cured?
That depends on the sealant used, so please follow the time we give you.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.
What we cannot put right
In fairness, there are a few things sealant will not fix:
- A frame that has rotted at the joint
- Worn gaskets, brush seals or a door that has dropped
- Damp problems in the wall away from the window
If you’re not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer before you book.
Where we work in Palmer's Green
- uPVC windows
- Composite doors

What happens if it’s left?
A cracked joint around a frame lets rain into the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. Resealing now is a small job by comparison. Older cottages and farmhouses around Palmer's Green can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
What you get with us
- White, clear, grey or another colour, product permitting

We quote each job individually. These are the things that affect it:
- The number of rooms or windows
- Whether old sealant or filler has to be cut out
- The type of sealant required
- Mould in or behind the old joints
