Window mastic for homes and businesses in Winklebury
From a single sill to a whole house of windows, the work is priced before anything is done. Just ring 0345 464 0079 or drop us an email and tell us how many frames there are and how they’re reached. We’re often asked to deal with mastic that’s falling out in pieces and draughty joints inside around the window, on aluminium frames, patio & French doors and uPVC windows.
In smaller places like Winklebury, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. Each frame material needs the right sealant against the right wall.
Every job comes with a 12-month guarantee, wherever you are in Hampshire.

Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Clear any debris from frame drain holes
- Look round the frames every year or so
- Avoid blasting the frames with a pressure washer
- Keep solvents and bleach off the sealant
Wipe the frames with soapy water when you clean the windows, and avoid solvent cleaners on the sealant.
Draughts get worse, not better. As the old mastic shrinks further, more air gets through, and a cold room gets colder. Resealing closes it.
Why deal with it now?
Failed mastic is not a reason to replace sound windows. If the frames and glass are in good order, resealing the joints is often all that is needed. Problems with the glass or gaskets are for a window company, and we’ll say so. Around Winklebury, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.
Why us?

What affects the cost of window mastic
Every job gets its own quote. This is what makes a difference:
- The amount of work
- How many rooms, windows or areas are involved
- Any mould that needs treating
- Access and height
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we will go through it with you.
What to tell us for a quote
There’s no need for technical detail. It helps if you can tell us:
- If someone has resealed it before
- The problem you’ve noticed
- Pictures of the joints, sent by email
- Whether it’s a home or a business
To get a quote, call 0345 464 0079 or send us an email and tell us where the job is and what the problem looks like. You will have a clear quote before any work starts.
How the visit works
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. It normally takes a few hours for a handful of frames, longer for a whole house. Parking around Winklebury is generally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- We check each frame and agree which ones need doing.
- We remove the old mastic and clean the frame and the wall.
- We fit backing rod in deep gaps so the sealant is the right depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Finally we tidy up and check each joint.
How to prepare
- Tell us about any previous sealing or DIY attempts
- Tell us about any water getting in
- Clear items away from the joints we’re working on
Getting a quote
Every job is quoted individually, so start by telling us what you need. Simply phone 0345 464 0079 or drop us an email and describe the job and send photos if you have them.

Frames and glazing around Winklebury
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

What we’re called out for in Winklebury
Sills take more water than any other part of a window, and the ends of the sill, where it meets the wall, are where it gets in. When that sealant fails, water gets into the wall or under the frame.
Most people get in touch after spotting one of these:
- Leaking joints at the ends of sills
- Rain getting in at the frame or under the sill
- Untidy mastic left by window fitters
- White mastic on grey or black frames
For site and facilities teams at buildings such as Castle Hill Infant School, its window and door frames need their mastic kept sound, just like a home’s.

Surface by surface
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.
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.
