Window mastic in Balmore
Most frames have an outside joint and an inside one. The external joint is the weather seal; the internal joint closes the gap to the plaster and stops draughts. Either or both can be done. If you’re dealing with a bead that doesn’t match the frame and cracked internal joints between frame and plaster, we can help.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Wind-driven rain finds any gap around a frame or sill, so the mastic there works hard.
Every job comes with our one-year guarantee.

DIY sealant or a professional job?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.

Aftercare tips
A little care helps the new joints last. Our advice:
- Air rooms to keep condensation down around windows
- Wash the frames with mild soapy water
- Do not paint over the silicone
- Make sure the drainage slots are not blocked
Try not to touch the new joint while it cures, following the cure time we give you. Keep jet washers away from the frames.
On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.
Balmore homes and the weather
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that. Balmore 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.
For an older house near a landmark such as Cadder Parish Church, the joint between an old wall and a newer frame is usually the first place rain gets in. If you let a flat or house near Bishopbriggs station, renewing tired window mastic between tenants heads off draught and damp complaints.

Signs you need window mastic in Balmore
Plenty of failed mastic was poorly applied in the first place. Mastic laid onto dusty, damp or crumbling surfaces didn’t grip properly, so it comes away long before its time.
Most people get in touch when they notice one of these:
- Gaps between the frame and the inside reveal
- Mastic that has split away from the wall
- Old mastic that has gone black or come away
- Gaps left after new windows were fitted
Managing a site like Bishopbriggs Academy? Then its window and door frames need their mastic kept sound, just like a home’s.
What your quote should include
- What guarantee comes with the work
- How the surfaces are prepared before sealing
- Which colour the sealant will be
- What product goes in the joint
What the job involves on each surface
Composite doors
Front doors take the weather head on, and the top and bottom corners tend to fail first. Those corners get the most care.
Aluminium frames
Coated aluminium needs a compatible sealant and we avoid acetoxy silicones, which can react with some metals. We use a neutral-cure product.
What happens if it’s left?
Failed mastic is not a reason to replace sound windows. If the frames and glass are in good order, resealing the joints is often all that is needed. Problems with the glass or gaskets are for a window company, and we’ll say so. In an older home around Balmore, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
What it costs depends on the amount of work, how much old material has to come out and access to the work. We give a clear quote before any work starts.

What we do, step by step
At the end, we look at the finished work together and tell you how long to leave it. The work normally takes a few hours for a handful of frames, longer for a whole house, depending on the size of the job. For a place like Balmore, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We check each frame and agree which ones need doing.
- Next the failed sealant is cut away and the joint cleaned.
- Where gaps are deep, backing rod goes in first.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- We clear up and check every joint is fully closed.
How to prepare
- Keep pets and children clear of the area while we work
- Clear the area around the work
- Tell us about access, such as stairs, a lift or high-level joints
