Why it’s worth doing now in North Stoke

A cracked joint around a frame lets rain into the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. A reseal is a much smaller job. Where a wall is exposed, as many are in small places like North Stoke, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.

What you get with us

  • We leave the area clean and tidy
  • White, clear, grey or another colour, product permitting

How it works

The work is kept neat and contained to the area we’re working on. Expect the work to take most of a day for a typical house, less for a few frames, and we tell you how long to leave it before we go. Somewhere as small as North Stoke, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We check each frame and agree which ones need doing.
  2. Next the failed sealant is cut away and the joint cleaned.
  3. Where gaps are deep, backing rod goes in first.
  4. New exterior sealant goes on in a matching colour and is tooled smooth.
  5. We clear up and check every joint is fully closed.

Preparing for the visit

  • Keep pets and children clear of the area while we work
  • Let us know about earlier repairs to the joints
  • Where the joints are inside, avoid wetting them before we arrive

What window mastic looks like in North Stoke

Historic houses like Brightwell Manor (about 3.5 miles north-west) are a reminder that the area around North Stoke has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

If you live in an older home near St Mary the Virgin, frames set in older brick or stone need a sealant that suits the wall as well as the frame. If you let a flat or house near Cholsey station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Keeping the joints in good condition

Once the sealant has cured, a few habits help it last:

  • Clear any debris from frame drain holes
  • Avoid blasting the frames with a pressure washer
  • Look round the frames every year or so
  • Wipe condensation off the frames

Keep sill grooves and drainage slots clear, so rain drains out rather than building up at the sealant.

Look out for the warning signs: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. Any of these is worth a call.

How the job changes by surface

Aluminium frames

Aluminium moves with heat, and the frames are often slimmer than uPVC. A neat, narrow bead in a colour to match keeps the clean look.

Patio & French doors

Water at the foot of a door frame is not always the mastic: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We check before we reseal.

Common problems we fix in North Stoke

Mastic ages in the weather. Sunlight dries the surface out, until it loses its stretch and starts to crack.

Common reasons people contact us are:

  • Rushed sealant from a window installation
  • Old mastic that has gone black or come away
  • Hard, cracked sealant around windows
  • Rain getting in at the frame or under the sill

For site and facilities teams at buildings such as Wallingford School, larger buildings have plenty of frames, and the mastic around each one ages.
