- Gaps where the sill meets the wall
- Mastic that has split away from the wall
Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Window mastic for homes and businesses in Moodiesburn
Every window and door frame has a gap around it, and mastic is what closes it. Once that seal fails, wind and rain find the gap. Our applicators cut it out and replace it with a flexible, weatherproof sealant. Typical jobs include draughts coming in around windows and doors and a bead that doesn’t match the frame, on window sills, composite doors and patio & French doors.
Mastic can only go onto a dry joint, so outside work in Moodiesburn depends on the weather, and longer journeys are planned in advance. Let us know about access to every frame, including any upstairs.
A 12-month guarantee comes as standard.

Leave it or put it right?
A cracked joint around a frame lets rain into the wall. Over time that can mean damp patches, damaged plaster and rotting timber. Resealing now is a small job by comparison. In an older home around Moodiesburn, damp from a failed joint can get into timber and plaster.
Combining jobs into one visit is usually more efficient than separate visits, so tell us about everything that needs sealing. We will send you a clear quote for the lot.

Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Keep jet washers away from the mastic
- Ventilate rooms so frames don’t stay wet inside
- Check the mastic once a year
- Clear any debris from frame drain holes
On timber frames, keep the paintwork in good order, since wood that gets wet swells and shrinks more. Keep paint off the silicone itself.
A failed joint lets water into the wall a little at a time. You might not see it until plaster blows or a damp patch appears inside. Catching it early keeps the fix to a reseal.

Surface by surface
Timber windows & doors
Soft or rotten wood cannot be sealed successfully. If we find rot, we’ll tell you before going ahead, as that is a job for a joiner.
uPVC windows
uPVC expands and contracts noticeably with temperature, so the joint needs a low-modulus sealant that stays flexible. White is the usual colour, with brown, anthracite grey and black for coloured frames.
For landlords and businesses
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we are fully insured for the work.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements.
Common problems we fix in Moodiesburn
Timber windows bring their own problems. Mastic painted over many times cracks with the paint, and timber moves with moisture as well as temperature.
It’s worth asking for a quote if you see:
- White mastic on grey or black frames
- Gaps where the sill meets the wall
- Rain getting in at the frame or under the sill
- Draughty joints inside around the window
For landlords with property near Gartcosh station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Frames and glazing around Moodiesburn
Moodiesburn is in the west of Scotland, which is wetter than the east, which means the mastic around window and door frames has to cope with a lot of rain. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
For site and facilities teams at buildings such as Chryston High School, larger buildings have plenty of frames, and the mastic around each one ages.
