How we handle window mastic in Nyton
The new joint doesn’t have to be white. White, brown, anthracite grey, black and clear sealants are all available, so the line suits the frame instead of standing out. We are often asked to deal with gaps left after new windows were fitted and a bead that doesn’t match the frame, on timber windows & doors, window sills and patio & French doors.
In a village or hamlet like Nyton, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
Every job comes with our 12-month guarantee.

Aftercare tips
After the cure time, these simple habits help:
- Wash the frames with mild soapy water
- Clear any debris from frame drain holes
- Keep paint and stain on wooden frames in good order
- Paint up to the joint, not over it
Wipe the frames with soapy water when you clean the windows, and keep solvents and harsh chemicals off the joint.
On timber windows, water behind the joint can lead to rot. Once wood has rotted, it needs repair before it can be sealed, so it pays to reseal before that happens.
When something else is needed
To be straight with you, some problems need a different trade:
- A frame that has rotted at the joint
- Faulty window hardware
- Worn gaskets, brush seals or a door that has dropped
If you are not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer.

Window mastic in Nyton: local notes
Historic houses like Goodwood House (about 3.6 miles north-west) are a reminder that the area around Nyton has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Managing a site like Ormiston Six Villages Academy? Then larger buildings have plenty of frames, and the mastic around each one ages. Rented homes near Barnham station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Goodwood House, about 3.6 miles north-west, is one of the historic houses in the wider area around Nyton.

Leave it or put it right?
Draughts and leaks don’t always mean new windows. Where the frames are sound, new mastic normally deals with draughts and leaks at the edges. Problems with the glass or gaskets are for a window company, and we’ll say so. Around Nyton, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference.

Surface by surface
uPVC windows
Some uPVC windows were sealed at fitting with a quick bead that never bonded. It comes out, deep gaps get backing rod and the joint is resealed.
Composite doors
Draughts round the door leaf generally come from worn seals or adjustment, not the mastic. We will tell you if that’s what we find.
