How we handle window mastic in Horney Common
A window frame and the wall around it expand and shrink at different rates. Heat and cold make frames grow and shrink against brick or render that hardly moves. So the sealant has to stretch and recover, which is why we use a low-modulus product. We work on uPVC windows, timber windows & doors and window sills, and common reasons people get in touch are rushed sealant from a window installation and draughts coming in around windows and doors.
Around Horney Common, 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.
A one-year guarantee comes as standard.

What window mastic looks like in Horney Common
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In the older streets around Christ Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

DIY versus a professional finish
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.

How the visit works
Good joint work is mostly preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it usually takes a morning for a couple of windows and a door. Somewhere as small as Horney Common, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check how each frame can be reached safely.
- All the failed sealant is cut away.
- The surfaces are cleaned and left dry.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Before we arrive
- Keep pets and children clear of the area while we work
- Tell us about any previous sealing or DIY attempts
- Mention any leaks or damp you’ve noticed

Looking after it afterwards
A little care helps the new joints last. We recommend:
- Look round the frames every year or so
- Wipe condensation off the frames
- Keep jet washers away from the mastic
- Keep solvents and bleach off the sealant
A yearly look round the frames is enough. Small splits are simple to catch before they leak.
On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.

What else we do in Horney Common
What the job involves on each surface
Aluminium frames
Large aluminium doors have long joints down each side and across the head, and the threshold joint takes a lot of water. Each is cleaned, backed where deep and resealed.
Timber windows & doors
Soft or rotten wood cannot be sealed successfully. We’ll point out any rot we find, as that’s a job for a joiner.
Common problems we fix in Horney Common
Older frames were often sealed with products that set hard. Once it has hardened, the frame’s movement tears it from the wall, leaving a hairline gap down one side.
The problems people normally mention when they call include:
- White mastic on grey or black frames
- Mastic that’s falling out in pieces
- Cracked sealant at the sill ends
- Cracked internal joints between frame and plaster
For landlords with property near Buxted station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

- Damp problems in the wall away from the window
- A door that needs adjusting, rehanging or new seals
