Window & door mastic in East Ashling, West Sussex
Our applicators work in East Ashling on mastic around window and door frames, sills and patio doors. Old material cut out, joints cleaned and sealed neatly.

- Gaps where the sill meets the wall
How we handle window mastic in East Ashling
Frames and walls do not move together. 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 are often asked to deal with draughts coming in around windows and doors and damp patches on the reveal after heavy rain, on uPVC windows, patio & French doors and aluminium frames.
Around East Ashling, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
There’s a 12-month guarantee on every job, whatever its size.

DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
What window mastic looks like in East Ashling
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 West Dean House (about 4 miles north-east) are a reminder that the area around East Ashling 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.
Managing a site like Funtington Primary School? Then its window and door frames need their mastic kept sound, just like a home’s. Homes close to Church of St Andrew include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

How it works
When we arrive, we start by going over the job with you. We protect the surfaces around the joints before any work begins. The work usually takes a few hours for a few frames, or a day or more for a whole house. For a village or hamlet like East Ashling, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely.
- The surfaces are cleaned and left dry.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.

Aftercare tips
Aftercare is simple:
- Air rooms to keep condensation down around windows
- Look round the frames every year or so
- Keep paint off silicone joints
- Avoid harsh chemicals near the mastic
A yearly look round the frames is enough. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just ring 0345 464 0079 or drop us an email.
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.
Common problems we fix in East Ashling
Every frame moves through the day. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the masonry beside it stays put. A sealant that cannot keep up eventually tears.
People normally contact us when they notice something like this:
- White mastic on grey or black frames
- Cracked or shrunken mastic around the frame
- Rain getting in at the frame or under the sill
- Mastic that’s falling out in pieces
Letting a property close to Bosham station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

How the job changes by surface
uPVC windows
We clean the frame edge carefully so the plastic isn’t marked, then the sealant goes in between frame and wall.
Aluminium frames
Large aluminium doors have long joints down each side and across the head, and the bottom joint sees the most water. Each is cleaned, backed where deep and resealed.
For landlords and businesses
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can be quoted together.
