Window & door mastic in Broad Oak, East Sussex
Window mastic across Broad Oak and nearby, with every bit of old sealant taken out first and a one-year guarantee.
- Black, perished sealant on frames

- Hard, cracked sealant around windows
How we handle window mastic in Broad Oak
Most frames have an outside joint and an inside one. The external joint is the weather seal; inside, the joint between frame and plaster stops draughts and tidies the reveal. Either or both can be done. We work on aluminium frames, timber windows & doors and patio & French doors, and the jobs we see most are gaps left after new windows were fitted and gaps where the sill meets the wall.
Homes in small places like Broad Oak often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
You are covered for a year from the day we finish. If anything is not right with it, phone 0345 464 0079 or drop us an email.

How it works
Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes most of a day for a typical house, less for a few frames. Somewhere as small as Broad Oak, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away.
- Frame and wall are cleaned and must be dry before sealing.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
How to prepare
- Keep children and pets away from the work area
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any sign-in or site rules at work premises

Advice
What happens if it’s left?
Draughts and leaks do not always mean new windows. Where the frames are sound, new mastic generally deals with draughts and leaks at the edges. Problems with the glass or gaskets are for a window company, and we’ll say so. Where a wall is exposed, as many are in small places like Broad Oak, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are not sure whether it needs doing, phone 0345 464 0079 or drop us an email and we will give you an honest view and a quote.

What affects the cost of window mastic
The quote reflects the job in front of us. We look at:
- How many rooms, windows or areas are involved
- The type of sealant required
- Access and height
- The size of the job
What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.
Helping us quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- A few pictures by email, if you can
- What’s wrong with the joints now
- The address or postcode of the job
- Any previous sealing or DIY work
Every job is quoted individually, so start by telling us what you need. Simply call 0345 464 0079 or email us and describe the job, and pictures are welcome.
When to call us in Broad Oak
Joints that are too thin or too deep fail early. A thin smear across a wide gap has nothing to it, and a gap filled solid cannot flex. That is what backing rod is for.
It’s worth asking for a quote if you see:
- Cracked or shrunken mastic around the frame
- Rain getting in at the frame or under the sill
- Gaps between the frame and the inside reveal
- Rushed sealant from a window installation
If you let a flat or house near Stonegate station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
Questions to ask before you book
- Is the old sealant removed completely?

How the job changes by surface
Patio & French doors
The joints around patio doors run a long way, top, sides and threshold. Most leaks start at the bottom corners, so they get particular care.
Composite doors
Front doors take the weather head on, and the top and bottom corners tend to fail first. Those corners get the most care.

Should I try it myself first?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Windows and doors in Broad Oak
Historic houses like Bateman's (about 4.2 miles east) are a reminder that the area around Broad Oak 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. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For site and facilities teams at buildings such as Broad Oak Community Primary School, the mastic around its windows and doors needs looking after like any other building’s. Homes close to Ebenezer Chapel include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
