Window mastic for homes and businesses in Leigh
The mastic around a window or door seals the gap between the frame and the wall. Once that seal fails, wind and rain find the gap. Our applicators cut it out and replace it with a flexible, weatherproof sealant. Common call-outs are for black, perished sealant on frames and sealant in the wrong colour for the frame, across uPVC windows, timber windows & doors and window sills.
Outdoor sealant needs dry, clean surfaces, so work on frames around Leigh is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
There’s a 12-month guarantee on every job.

The process
Once we’re on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take most of a day for a typical house, less for a few frames. For a village or hamlet like Leigh, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We check each frame and agree which ones need doing.
- The old mastic is cut out and the surfaces cleaned back.
- Where gaps are deep, backing rod goes in first.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Finally we tidy up and check each joint.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Let us know about stairs, lifts or work at height
- Tell us if parking is tricky

Advice
How the job changes by surface
Window sills
Where a sill meets brick or render, the ends often crack first. A tight seal at each end keeps rain out of the wall.
Composite doors
Draughts round the door leaf normally come from worn seals or adjustment, not the mastic. We will tell you if that’s what we find.
Other services in Leigh
Window mastic in Leigh: local notes
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 let a flat or house near Betchworth station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. For site and facilities teams at buildings such as Burys Court School, larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around Church of St Bartholomew, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

DIY versus a professional finish
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
Why deal with it now?
Resealing frames is a short job: the visit takes a morning for a couple of windows and a door. Wait for damp to appear and there may be plaster and decorating to sort out too. Where a wall is exposed, as many are in small places like Leigh, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Doing several joints on one visit is normally more efficient than separate visits. You’ll get one clear quote for the whole job.
