About our window mastic in Upper Clatford
A cold draught around a closed window often comes from the frame edge. Resealing that joint can make a room feel noticeably less draughty. If the draught is through the window seals instead, we’ll tell you. We’re often asked to deal with white mastic on grey or black frames and rain getting in at the frame or under the sill, on window sills, uPVC windows and timber windows & doors.
Somewhere as small as Upper Clatford, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
The work is covered for a year after we finish. If anything is not right with it, call 0345 464 0079 or drop us an email.

What we do, step by step
When we arrive, we start by going over the job with you. We protect the surfaces around the joints before any work begins. Most jobs take a few hours for a handful of frames, longer for a whole house. In a small place like Upper Clatford, access is generally the main thing to plan. 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.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
How to prepare
- Let us know about earlier repairs to the joints
- Tell us if parking is tricky
- Mention any sign-in or site rules at work premises

Window mastic in Upper Clatford: local notes
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you look after a building such as Balksbury Junior School, its window and door frames need their mastic kept sound, just like a home’s. Homes close to Church of All Saints include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Leave it or put it right?
A quick bead over the top of old mastic looks like an easy fix, but new sealant cannot bond to old, crumbling mastic. It peels before long, and water still gets in behind. Proper resealing starts with removing the old joint. Older cottages and farmhouses around Upper Clatford can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, call 0345 464 0079 or email us for an honest opinion and a quote.

What we’re called out for in Upper Clatford
Every frame moves through the day. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the brick or render around it hardly moves. A sealant that cannot keep up eventually tears.
People usually contact us after spotting one of these:
- Cracked sealant at the sill ends
- Mastic that’s falling out in pieces
- Whistling draughts around closed windows
- Untidy mastic left by window fitters
For landlords with property near Andover station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

- How long the guarantee is
- What insurance they hold

Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
