Window & door mastic in Goose Green, West Sussex
Problem with your window and door frames in Goose Green? We remove the old material, prepare the joints and seal them properly.
- Rain getting in at the frame or under the sill
- Cracked internal joints between frame and plaster
- Untidy mastic left by window fitters
How we handle window mastic in Goose Green
A cold draught around a closed window often comes from the frame edge. A new joint stops the air getting through. If the draught is through the window seals instead, we’ll tell you. Common call-outs are for rain getting in at the frame or under the sill and gaps where the sill meets the wall, across aluminium frames, timber windows & doors and composite doors.
Somewhere as small as Goose Green, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
All our work comes with our 12-month guarantee.

What the job involves on each surface
Window sills
Sills catch the water running down the glass, so the sill ends and the joint under the frame are vital. Each is cleaned out and resealed.
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.

What window mastic looks like in Goose Green
Historic houses like Parham House (about 4.5 miles south-west) are a reminder that the area around Goose Green 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. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For site and facilities teams at buildings such as Rydon Community College, its window and door frames need their mastic kept sound, just like a home’s. In the older streets around The Parish Church of St Mary, the joint between an old wall and a newer frame is generally the first place rain gets in. Rented homes near Billingshurst station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Advice
Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Keep paint off silicone joints
- Use gentle cleaners on frames and sealant
- Clear any debris from frame drain holes
- Air rooms to keep condensation down around windows
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: split or missing mastic, gaps, damp patches inside or black mould on the reveal. Any of these is worth a call.

Leave it or put it right?
Once mastic fails, rain can get between the frame and the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. Resealing now is a small job by comparison. Older cottages and farmhouses around Goose Green can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first and give you a clear quote before work begins.
