Window & door mastic in Hundred Acres, Hampshire
Window and door frames in Hundred Acres need attention? We cut out the old, prepare the joints and apply the right sealant.
- Draughty joints inside around the window
- Cracked or shrunken mastic around the frame
- Draughts coming in around windows and doors
Window mastic in Hundred Acres, done properly
The new joint doesn’t have to be white. White, brown, anthracite grey, black and clear sealants are all available, so the bead blends with the window rather than framing it. We work on patio & French doors, uPVC windows and timber windows & doors, and the jobs we see most are black, perished sealant on frames and rushed sealant from a window installation.
Around Hundred Acres, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

How the job changes by surface
Timber windows & doors
Soft or rotten wood can’t be sealed successfully. We’ll point out any rot we find, as that’s a job for a joiner.
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A tidy bead in anthracite grey, black or a matching colour keeps the clean look.
Common problems we fix in Hundred Acres
Sun, frost and rain wear sealant out. UV light hardens the outside of the bead, until it loses its stretch and starts to crack.
People usually contact us after spotting one of these:
- Sealant in the wrong colour for the frame
- Cracked internal joints between frame and plaster
- Cracked sealant at the sill ends
- Hard, cracked sealant around windows
For an older house near a landmark such as Church of St Nicholas, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Hundred Acres: your questions answered
I let a flat near Fareham station. Can you help?
Yes, we work for letting agents and landlords. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear quote.
Do you cover Hundred Acres for window mastic?
Yes, Hundred Acres is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or drop us an email and let us know what needs doing.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises. We can talk about working times when we quote.
Do you remove the old sealant?
Yes, always, and completely. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Do you work on first-floor windows?
Yes, as long as they can be reached safely. Let us know about access when you ask for a quote so we can plan the job.
Do I need to be at home?
Access is agreed with you when the job is booked. Indoors, that normally means someone at home.
Where are you based?
We work from Crawley. Our applicators cover Hundred Acres.
Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.

DIY versus a professional finish
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
What window mastic looks like in Hundred Acres
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Rented homes near Fareham station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Why it’s worth doing now in Hundred Acres
Failed mastic is not a reason to replace sound windows. Where the frames are sound, new mastic normally deals with draughts and leaks at the edges. Problems with the glass or gaskets are for a window company, and we’ll say so. Around Hundred Acres, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
The cost depends on the amount of work, how hard the old material is to remove and access to the work. We give a clear quote before any work starts, so you know where you stand.
