Window & door mastic in East Dean, East Sussex
Window mastic across East Dean and nearby, with every bit of old sealant taken out first and a 12-month guarantee.
- Damp patches on the reveal after heavy rain
- Leaking joints at the ends of sills
- Mastic that’s falling out in pieces
What happens if it’s left?
Resealing frames is a short job: it takes anything from an hour or two to a full day, depending on how many frames there are. Wait for damp to appear and there may be plaster and decorating to sort out too. In a small place like East Dean, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Doing several joints on one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll send you a clear quote for the lot.

How we handle window mastic in East Dean
Homes in East Dean have every kind of window: from uPVC casements to timber and aluminium, plus patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. We work on patio & French doors, window sills and composite doors, and the jobs we see most are black, perished sealant on frames and a bead that doesn’t match the frame.
Somewhere as small as East Dean, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
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.
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Repaint timber before it’s bare
- Walk round the house once a year and look at the joints
- Clear any debris from frame drain holes
- Clean frames with a soft cloth and soapy water
Try not to touch the new joint while it cures, for as long as we advise. Don’t point a pressure washer at the joints.
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 the job involves on each surface
Patio & French doors
Patio and French doors have the longest joints on most houses. Most leaks start at the bottom corners, so they get particular care.
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.

East Dean: your questions answered
Does living near the coast affect window mastic in East Dean?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Do you work for landlords with property near Eastbourne station?
Yes, we work for landlords and agents. You can ring 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before work begins.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is usually more efficient.
Do you work on first-floor windows?
Yes, if safe access is possible. Higher or awkward frames may need extra access, and we’ll confirm what’s needed.
Where do you work from?
Our base is in Crawley, and we work across South East England, London and Scotland.
How do I get a quote for window mastic in East Dean?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we’ll talk you through it.
Can resealing stop a draught around my window?
It will if the frame joint is the problem. We find where the air is coming from before we reseal.
Can I paint over the new sealant?
Not if it’s silicone. Tell us your decorating plans and we’ll pick a sealant to suit.
What window mastic looks like in East Dean
East Dean is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you let a flat or house near Eastbourne station, renewing tired window mastic between tenants heads off draught and damp complaints. In the older streets around The Parish Church of St Simon and St Jude, the joint between an old wall and a newer frame is normally the first place rain gets in.

How it works
Before we leave, we go over the finished joints with you. The visit itself generally takes a few hours for a handful of frames, longer for a whole house, depending on how much there is to do. In a small place like East Dean, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- Plan for the work area to be out of bounds to pets and children
- Clear items away from the joints we are working on

What we cannot put right
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Damp coming through the wall itself rather than the frame joint
- Faulty window hardware
- Rotten timber, which needs a joiner first
