Signs you need window mastic in Leigh Green
Joint shape matters as much as the product. A skim of sealant over a wide gap soon tears, while a joint packed solid can’t stretch. Backing rod sets the right depth.
Common reasons people contact us are:
- Cold air getting in at the frame edge
- Mastic that has split away from the wall
- Gaps left after new windows were fitted
- Cracked internal joints between frame and plaster
In the older streets around Parish Church of St Mildred, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

How we handle window mastic in Leigh Green
Around Leigh Green we seal all kinds of frames: from uPVC casements to timber and aluminium, along with patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. We work on aluminium frames, uPVC windows and timber windows & doors, and common reasons people get in touch are cracked or shrunken mastic around the frame and draughty joints inside around the window.
In a village or hamlet like Leigh Green, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
You are covered for a year from the day we finish. If anything is not right with it, call 0345 464 0079 or email us.

Leigh Green homes and the weather
Historic houses like Smallhythe Place (about 1.9 miles south) are a reminder that the area around Leigh Green has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Rented homes near Appledore (Kent) station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Managing a site like Tenterden Church of England Junior School? Then larger buildings have plenty of frames, and the mastic around each one ages.

Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Keep drainage slots and sill grooves clear
- Avoid harsh chemicals near the mastic
- Don’t aim a pressure washer at the joints
- Wipe condensation off the frames
Wipe the frames with soapy water when you clean the windows, and keep solvents and harsh chemicals off the joint.
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.
DIY versus a professional finish
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Why act early in Leigh Green
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. Around Leigh Green, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

Take a look at what affects the cost and our reviews.
What the job involves on each surface
Patio & French doors
The joints around patio doors run a long way, top, sides and threshold. Most leaks start at the bottom corners, so they get particular care.
Composite doors
A composite door generally sits in a plastic outer frame, and the joint around it is sealed like a window. We match the colour to the frame.
