About our window mastic in Chartway Street
Around Chartway Street we seal all kinds of frames: uPVC, aluminium, timber and composite, plus patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. We work on window sills, timber windows & doors and aluminium frames, and people most often call us about cracked sealant at the sill ends and cracked internal joints between frame and plaster.
Around Chartway Street, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
Your job is guaranteed for a year, as with all our work.

Your questions about window mastic in Chartway Street
I let a flat near Harrietsham station. Can you help?
Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or email us with the details for a clear quote.
Will you come out to Chartway Street?
Yes, smaller places are covered as well as towns. 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 remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
How long will my window job take?
A few frames take a few hours, while a whole house takes longer. We confirm the timing with your quote.
What do you need from me for a quote?
Just the basics: where it is, what you’ve noticed and how we reach it. Then ring 0345 464 0079 or email us.
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.
Will resealing my frames help with draughts?
Yes, if the air is getting in around the frame. If it’s coming through the window seals, we’ll tell you.
Do I have to be there?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you don’t need to watch us work.
How it works
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a morning for a couple of windows and a door, and the area is left clean. Somewhere as small as Chartway Street, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
How to prepare
- Tell us about any previous sealing or DIY attempts
- Move anything stored near the joints
- Let us know about parking restrictions

What the job involves on each surface
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We can talk through the options.
Aluminium frames
Coated aluminium needs a compatible sealant. Neutral-cure sealant is the safe choice.
When something else is needed
New sealant can’t fix everything, and we’d rather say so up front. Sealant won’t put right:
- Damp problems in the wall away from the window
- A door that needs adjusting, rehanging or new seals
- Broken hinges, locks or handles
If in doubt, phone 0345 464 0079 or email us and we will say what we think before you book.

Windows and doors in Chartway Street
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 Leeds Castle (about 2 miles north) nearby, there’s older building stock in the area around Chartway Street as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
For landlords with property near Harrietsham station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Managing a site like Kingswood Primary School? Then its window and door frames need their mastic kept sound, just like a home’s. Homes close to St Peter's and St Paul's Church include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Make sure the drainage slots aren’t blocked
- Walk round the house once a year and look at the joints
- Ventilate rooms so frames don’t stay wet inside
- Keep jet washers away from the mastic
Wipe the frames with soapy water when you clean the windows, and avoid solvent cleaners on the sealant.
Water gets in quietly when mastic fails. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.
