Window mastic in Broomhouse
There are two joints on most windows. The external joint is the weather seal; the internal joint closes the gap to the plaster and stops draughts. We seal one or both, depending on what’s needed. We work on composite doors, timber windows & doors and aluminium frames, and the jobs we see most are white mastic on grey or black frames and black, perished sealant on frames.
Outdoor sealant needs a dry surface, so window work around Broomhouse is planned around the weather. Tell us about access to all the windows and doors, upstairs included.
All of our work is guaranteed for twelve months.

What affects the cost of window mastic
Jobs vary more than people expect. The main factors:
- The amount of work
- Whether old sealant or filler has to be cut out
- When we can work, for business premises
- How many rooms, windows or areas are involved
What you pay reflects the work, not guesswork. That’s why we ask about the job first.

Why act early in Broomhouse
Working on frames from a ladder with a sealant gun is not easy, especially on upper floors. We cut out properly, back deep gaps and tool every joint neatly, in a sealant suited to the wall. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Doing several joints on one visit is generally more efficient than separate visits. We will give you a clear price for the lot.
Why us?

- Every job guaranteed for a year

What the job involves on each 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’s a job for a joiner.
uPVC windows
Some uPVC windows were sealed at fitting with a quick bead that never bonded. It comes out, deep gaps get backing rod and the joint is resealed.
Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Avoid harsh chemicals near the mastic
- Paint up to the joint, not over it
- Ventilate rooms so frames do not stay wet inside
- Keep drainage slots and sill grooves clear
Try not to touch the new joint while it cures, for as long as we advise. Do not point a pressure washer at the joints.
Signs to watch for: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. If you notice one, it’s time to get the joint looked at.
When to call us in Broomhouse
Mastic ages in the weather. UV light hardens the outside of the bead, and over the years it loses its give, cracks and comes away.
Signs it’s time to call us include:
- White mastic on grey or black frames
- Gaps left after new windows were fitted
- Cracked or shrunken mastic around the frame
- Whistling draughts around closed windows
If you live in an older home near Baillieston St Andrew's Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

I’m a tenant. Can you help?
Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.
Do you seal inside as well as outside?
Yes. Draughts often come through the inside gap too, so sealing both is often worthwhile.
What sealant work cannot fix
A few problems are outside what sealant work can do:
- A door that needs adjusting, rehanging or new seals

What we do, step by step
When we arrive, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before any work starts. Most jobs take most of a day for a typical house, less for a few frames. Outdoor work around Broomhouse depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Before we arrive
- Let us know about earlier repairs to the joints
- Let us know about parking restrictions
- Let us know if you’ve seen damp or leaks

Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. Much of Glasgow is built from red and blond sandstone, and sandstone is porous, so any sealant against it has to be one that won’t stain or attack it.
