Frames and glazing around Stone Corner
The South East is one of 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 Smallhythe Place (about 1.4 miles north-west) are a reminder that the area around Stone Corner has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Historic houses such as Smallhythe Place, about 1.4 miles north-west, show how far back building around Stone Corner goes, and older homes nearby need a sealant that suits their walls.

Looking after it afterwards
Looking after new joints is easy:
- Wash the frames with mild soapy water
- Walk round the house once a year and look at the joints
- Paint up to the joint, not over it
- Wipe condensation off the frames
Have a look at the joints once a year, ideally after winter. Small splits are simple to catch before they leak.
A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and a cold room gets colder. Resealing closes it.
When something else is needed
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- A door that needs adjusting, rehanging or new seals
- Soft or decayed wood in the frame
- Misting between the panes of a double-glazed unit (that needs a new unit)
If you’re not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer.

Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
What the job involves on each surface
Composite doors
Front doors take the weather head on. Those corners get the most care.
Patio & French doors
Not every patio door leak is a mastic problem: blocked drain slots, worn brush seals and threshold details can let water in too. We check before we reseal.
When to call us in Stone Corner
Sun, frost and rain wear sealant out. Sunlight dries the surface out, until it loses its stretch and starts to crack.
These are the problems we’re asked about most:
- Sealant in the wrong colour for the frame
- Rain getting in at the frame or under the sill
- Gaps left after new windows were fitted
- Gaps where the sill meets the wall
If you let a flat or house near Appledore (Kent) station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
