How we handle window mastic in Chiddingstone Causeway
Frames and walls do not move together. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. So the sealant has to stretch and recover, which is why we use a low-modulus product. If you have draughts coming in around windows and doors and white mastic on grey or black frames, we can help, on uPVC windows, aluminium frames and window sills alike.
Around Chiddingstone Causeway, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
Whatever the size of the job, you get the same 12-month guarantee.

When it is not the sealant
New sealant cannot fix everything, and we’d rather say so up front. Sealant will not put right:
- Faulty window hardware
- A frame that has rotted at the joint
- Draughts through the window seals rather than the frame
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think before you book.
Surfaces we seal
- uPVC windows
- Timber windows & doors
- Composite doors
- Patio & French doors
- Aluminium frames
- Window sills
What else we do in Chiddingstone Causeway
Common questions in Chiddingstone Causeway
Will you come out to Chiddingstone Causeway?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is Chiddingstone Causeway in your area for window mastic?
Yes. We work across London and the South East, and Chiddingstone Causeway is part of that. You can ring 0345 464 0079 or send us an email and tell us what needs doing.
Can you quote for more than one area?
Yes. More than one area can be quoted together.
What do you need from me for a quote?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply ring 0345 464 0079 or drop us an email.
Are you insured?
Yes. We are fully insured.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.
How long does it take to reseal the windows on a house?
A few frames take a few hours. You’ll get a timescale with the quote.
Can new window sealant be painted?
That depends on the product. Some hybrid sealants can be painted; silicone can’t. Mention any painting plans before work begins.
What we’re called out for in Chiddingstone Causeway
Joints that are too thin or too deep fail early. A skim of sealant over a wide gap soon tears, while a joint packed solid cannot stretch. That’s what backing rod is for.
The problems people usually mention when they call are:
- White mastic on grey or black frames
- Mastic that has split away from the wall
- Leaking joints at the ends of sills
- Old mastic that has gone black or come away
Letting a property close to Penshurst station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
Questions to ask before booking
- Who does the work, and how experienced they are
- Whether the sealant suits the joint
- When the joint can take water or movement
- The length of the guarantee
Leave it or put it right?
If you are painting or rendering, reseal at the same time. Fresh joints finish the job neatly, and it’s easier while the walls are being worked on anyway. Around Chiddingstone Causeway, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
Why us?
- An ARBOMaster approved applicator
- Anti-fungal sanitary silicone in wet areas
- White, clear, grey or coloured to suit, where the product allows
- Fully insured

Different surfaces, different methods
Window sills
The end joints of a sill tend to fail before the rest. We reseal them so rain cannot run into the wall.
Patio & French doors
Water at the foot of a door frame is not always the mastic: blocked drain slots, worn brush seals and threshold details can let water in too. We check before we reseal.
Landlords, agents and businesses in Chiddingstone Causeway
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we will quote.
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
What window mastic looks like in Chiddingstone Causeway
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. With historic houses such as Chiddingstone Castle (about 1.5 miles south-west) nearby, there’s older building stock in the area around Chiddingstone Causeway as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you live in an older home near Church of St Luke, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
