About our window mastic in Foxcotte
There are two joints on most windows. Outside, the mastic keeps rain out; inside, the joint between frame and plaster stops draughts and tidies the reveal. We seal one or both, depending on what’s needed. We work on uPVC windows, patio & French doors and timber windows & doors, and common reasons people get in touch are hard, cracked sealant around windows and white mastic on grey or black frames.
Homes in small places like Foxcotte often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
All of our work is guaranteed for twelve months, in Foxcotte and everywhere else we cover.

What we can’t put right

- Misting between the panes of a double-glazed unit (that needs a new unit)
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think.

What else we do in Foxcotte
Leave it or put it right?
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. If we find failed glass units or worn seals, we’ll tell you. Where a wall is exposed, as many are in small places like Foxcotte, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts.

Questions from Foxcotte
Do you cover smaller places like Foxcotte?
Yes, Foxcotte is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you work for landlords with property near Andover station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear price.
Can I paint over the new sealant?
It depends on the sealant. Silicone is not paintable, but some hybrid sealants are. Tell us if you are decorating and we’ll choose accordingly.
Will it make a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Is it OK to seal over old sealant?
No. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you do not need to watch us work.
Can I do it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Do you take out the old sealant first?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Keep drainage slots and sill grooves clear
- Check the mastic once a year
- Do not paint over the silicone
- Avoid blasting the frames with a pressure washer
Timber frames need their paint kept up, since wood that gets wet swells and shrinks more. Paint up to the joint, not over the silicone.
Look out for the warning signs: split or missing mastic, gaps, damp patches inside or black mould on the reveal. If you notice one, it’s time to get the joint looked at.
How it works
At the end, we look at the finished work together and explain the cure time. The visit itself generally takes a few hours for a few frames, or a day or more for a whole house, depending on the size of the job. Somewhere like Foxcotte needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We start by checking each window and door with you.
- The old mastic is cut out and the surfaces cleaned back.
- Deep gaps are filled with backing rod to set the depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Finally we tidy up and check each joint.
Before we arrive
- Tell us about any water getting in
- Tell us about access, such as stairs, a lift or high-level joints
- Keep pets and children clear of the area while we work

Letting a property close to Andover station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Different surfaces, different methods
Patio & French doors
Heavy door frames can move more than windows. A flexible sealant copes with that.
Window sills
Stone and concrete sills have their own joints, and the joint under the frame can let rain run behind. We seal those with a sealant suited to masonry.
Do you need window mastic in Foxcotte?
Joints that are too thin or too deep fail early. A thin smear across a wide gap has nothing to it, while a joint packed solid cannot stretch. That is what backing rod is for.
These are the problems we’re asked about most:
- Water coming in at the bottom corners of a door
- Cracked internal joints between frame and plaster
- White mastic on grey or black frames
- Mastic that has split away from the wall
For site and facilities teams at buildings such as Harrow Way Community School, the mastic around its windows and doors needs looking after like any other building’s.
