Window & door mastic in Binsted, West Sussex
Problem with your window and door frames in Binsted? We remove the old material, prepare the joints and seal them properly, with a 12-month guarantee.
- Cracked internal joints between frame and plaster
- Leaking joints at the ends of sills
- Water coming in at the bottom corners of a door
Window mastic in Binsted
Every window and door frame has a gap around it, and mastic is what closes it. Once that seal fails, wind and rain find the gap. Our applicators cut it out and replace it with a flexible, weatherproof sealant. We are often asked to deal with cracked internal joints between frame and plaster and gaps where the sill meets the wall, across uPVC windows, composite doors and timber windows & doors.
In a village or hamlet like Binsted, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
There’s a 12-month guarantee on every job, whatever its size.

How the visit works
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours for a handful of frames, longer for a whole house and we leave things clean and tidy. Somewhere as small as Binsted, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
How to prepare
- Mention any parking rules near the property
- Let us know about earlier repairs to the joints
- Move anything stored near the joints
Getting a quote
Getting a quote is simple: let us know the job and the location, and roughly how big it is. A few photos by email make the job easier to understand.
Advice
Leave it or put it right?
The work is quick compared with the damage it prevents: it takes most of a day for a typical house, less for a few frames. Wait for damp to appear and there may be plaster and decorating to sort out too. Where a wall is exposed, as many are in small places like Binsted, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.

What the job involves on each surface
Patio & French doors
Water at the foot of a door frame isn’t always the mastic: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We look for the cause first.
Aluminium frames
Coated aluminium needs a compatible sealant, and acetoxy silicones aren’t used, as they can attack some metals. Neutral-cure sealant is the safe choice.
How to look after the new joints
To keep the joints looking good and working properly:
- Wash the frames with mild soapy water
- Repaint timber before it’s bare
- Avoid blasting the frames with a pressure washer
- Don’t use solvent cleaners on the joint
Silicone can’t generally be painted, so mention any painting plans before any work starts. We can use a paintable sealant where that matters.
A failed joint lets water into the wall a little at a time. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.
Signs you need window mastic in Binsted
A lot of older mastic was never designed to stay flexible. Once it’s rigid, every bit of frame movement pulls at it, leaving a hairline gap down one side.
People generally contact us when they notice one of these:
- Whistling draughts around closed windows
- Cracked internal joints between frame and plaster
- Rain getting in at the frame or under the sill
- Gaps left after new windows were fitted
If you look after a building such as Walberton and Binsted CofE Primary School, the mastic around its windows and doors needs looking after like any other building’s.
What your quote should include
- What guarantee comes with the work
- What insurance they hold

- How the joint is cleaned and prepared
What affects the cost of window mastic
There’s no set price list. The quote depends on:
- The size of the job
- Working hours on commercial sites
- Whether old sealant or filler has to be cut out
- The product the joint needs
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
What we need to know
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Whether it has been sealed before
- Where the job is, and your postcode
- Roughly how big the job is
- The problem you’ve noticed
We don’t publish a price list, because every job is different. Instead, we give you a clear quote for your job. To get started, phone 0345 464 0079 or email us.

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.
In the older streets around Church of St Mary, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Letting a property close to Ford station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Your questions about window mastic in Binsted
Will you come out to Binsted?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
I let a flat near Ford station. Can you help?
Yes, we work for landlords and letting agents. You can call 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before we start.
How long does it take to reseal the windows on a house?
The work takes most of a day for a typical house, less for a few frames. Access and how stubborn the old mastic is affect the time most.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Can you get sealant to suit coloured frames?
Yes. We can use white, brown, anthracite grey, black or clear.
What information do you need?

Do you work on first-floor windows?
Yes, in most cases. We plan safe access before the job, so mention the height and anything in the way.
Will resealing my frames help with draughts?
In many cases. Air often gets in between the frame and the wall, and resealing inside and out closes it.
