About our window mastic in High Salvington
Over two decades of sealing frames has taught us which products suit which walls. We are fully insured ARBOMaster approved applicators, and every job is covered by a 12-month guarantee. We’re often asked to deal with mastic that has split away from the wall and gaps where the sill meets the wall, on window sills, timber windows & doors and composite doors.
In smaller places like High Salvington, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. Each frame material needs the right sealant against the right wall.
Big or small, it’s backed by our one-year guarantee.

How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Air rooms to keep condensation down around windows
- Check the mastic once a year
- Don’t aim a pressure washer at the joints
- Paint up to the joint, not over it
Try not to touch the new joint while it cures, following the cure time we give you. Don’t point a pressure washer at the joints.
Signs to watch for: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. Any of these is worth a call.
What happens if it’s left?
Running fresh sealant over the old joint is tempting, but it will not grip old, dirty sealant. It soon lifts and the leak carries on behind it. Proper resealing starts with removing the old joint. Homes in smaller places like High Salvington can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
We do not show prices on the website, because each job is priced on what it involves. Call for a quick quote and we’ll talk you through it.

High Salvington homes and the weather
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Ecclesden Manor (about 3.1 miles south-west) are a reminder that the area around High Salvington has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
Homes close to St Peter include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame. For site and facilities teams at buildings such as Vale School, larger buildings have plenty of frames, and the mastic around each one ages.
