Window & door mastic in Wineham, West Sussex
Window and door frames in Wineham need attention? We cut out the old, prepare the joints and apply the right sealant, with a 12-month guarantee.
- Untidy mastic left by window fitters
- Sealant in the wrong colour for the frame
- Whistling draughts around closed windows
How it works
Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it generally takes a few hours for a few frames, or a day or more for a whole house. In a small place like Wineham, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we look at every frame and agree the list.
- 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.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Finally we tidy up and check each joint.
How to prepare
- Let us know about earlier repairs to the joints
- Move anything stored near the joints
- Plan for the work area to be out of bounds to pets and children

About our window mastic in Wineham
Behind a thin line of old mastic there’s sometimes a deep void. Packing it solid with sealant gives a joint that cannot flex, so we fit backing rod to set the right depth. The sealant then grips the two sides it should. If you are dealing with draughty joints inside around the window and mastic that’s falling out in pieces, we can help, on uPVC windows, aluminium frames and patio & French doors alike.
Mastic can only go onto a dry, clean joint, so window work in Wineham is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
There’s a 12-month guarantee on every job, whatever its size.

What we are called out for in Wineham
Some failures date back to when the windows were fitted. Mastic laid onto dusty, damp or crumbling surfaces didn’t grip properly, so it comes away long before its time.
People usually contact us after spotting something like this:
- Rain getting in at the frame or under the sill
- Gaps where the sill meets the wall
- Mastic that has split away from the wall
- Whistling draughts around closed windows
In and around Wineham, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.
What your quote should include
- How the joint is cleaned and prepared
- How hidden problems are handled
- Whether all the old sealant comes out first
- Whether they’re fully insured
Surface by surface
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, so we use a flexible, low-modulus sealant. White is the usual colour, with brown, anthracite grey and black for coloured frames.
Timber windows & doors
Where timber has rotted at the joint, it needs repairing first. We’ll point out any rot we find, as a joiner will need to deal with it.

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
When something else is needed
We will always be straight with you, so here’s what new sealant won’t do:
- Draughts through the window seals rather than the frame
- A frame that has rotted at the joint
- Damp problems in the wall away from the window
If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think.
Surfaces we seal
- Patio & French doors
- uPVC windows
- Window sills
- Composite doors
- Aluminium frames

Leave it or put it right?
Draughts and leaks don’t always mean new windows. Where the frames are sound, new mastic generally deals with draughts and leaks at the edges. If we find failed glass units or worn seals, we will tell you. Around Wineham, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
The cost depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before work begins.

Frames and glazing around Wineham
With historic houses such as Ockenden Manor (about 4.9 miles north-east) nearby, there’s older building stock in the area around Wineham as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For an older house near a landmark such as The Parish Church of St Peter, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
