How we handle window mastic in Strathbungo
If you can feel air around a shut window, the gap is often at the frame. A new joint stops the air getting through. Where the air is getting in through the window itself, we will say so. If you have cold air getting in at the frame edge and leaking joints at the ends of sills, we can put it right, on composite doors, window sills and timber windows & doors alike.
In a Scottish city, many flats have windows two, three or four floors up, where failing mastic is easy to miss. For a flat in Strathbungo, access is the first thing to plan.
A one-year guarantee comes with the work, just as it does everywhere we cover.

The process
There isn’t much for you to do on the day. Show us the job and we will take it from there. The job generally takes anything from an hour or two to a full day, depending on how many frames there are from start to finish. In a city area like Strathbungo, parking may be by permit or pay-and-display, so tell us what’s nearby. For flats, mention the door entry system and any shared-stair arrangements.
- First we look at every frame and agree the list.
- Next the failed sealant is cut away and the joint cleaned.
- Deep gaps are filled with backing rod to set the depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Every joint is checked before we leave.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks
- For business premises, tell us about site rules or sign-in

Why act early in Strathbungo
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 will say so. For landlords in Strathbungo, damp and leaks can be a Repairing Standard issue, so it’s worth fixing failed sealant before a tenant reports it.
The cost depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before any work starts, so you know where you stand.

When something else is needed
Some problems need a builder, plumber or other trade rather than us:

- Broken hinges, locks or handles
- Penetrating damp from a failed cavity tray or render

Frames and glazing around Strathbungo
With historic houses such as Pollok House (about 1.9 miles west) nearby, there’s older building stock in the area around Strathbungo as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. Glasgow’s tenements are largely red and blond sandstone, and sandstone is porous, so any sealant against it has to be one that won’t stain or attack it.
Letting a property close to Queens Park (Glasgow) station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Schools such as Shawlands Academy are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

Common problems we fix in Strathbungo
Water runs down the glass onto the sill, and the ends of the sill, where it meets the wall, are where it gets in. Failed sealant there lets rain into the wall or behind the frame.
The problems people normally mention when they call are:
- Cold air getting in at the frame edge
- Gaps between the frame and the inside reveal
- Old mastic that has gone black or come away
- Rushed sealant from a window installation
For an older house near a landmark such as Strathbungo U.P. Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Questions from Strathbungo
Is Strathbungo in your area for window mastic?
Yes. Our work covers the whole of Scotland, and Strathbungo is part of that. You can send an email to info@mrmastic.co.uk and let us know what needs doing, and we will give you a clear quote.
How do repairs to the shared parts of a tenement in Strathbungo get organised?
Most tenements arrange shared repairs through the owners or a property factor. The Tenements (Scotland) Act 2004 sets the rules for common parts if the deeds do not, and we can quote for the factor or the owners directly.
Can I do it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Do you guarantee window mastic?
Yes. Our 12-month guarantee covers every job, inside or out.
Can you seal the gap between the frame and the plaster indoors?
Yes. Outside is the weather seal; inside closes the gap to the plaster. We do one or both.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice.
Can you work on commercial sites?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Clean frames with a soft cloth and soapy water
- Make sure the drainage slots are not blocked
- Keep jet washers away from the mastic
- Air rooms to keep condensation down around windows
Timber frames need their paint kept up, since wood that gets wet swells and shrinks more. Paint up to the joint, not over the silicone.
Water gets in quietly when mastic fails. Often the first sign is a damp patch inside or flaking paint on the reveal. Catching it early keeps the fix to a reseal.

Patio & French doors
Heavy door frames can move more than windows. A flexible sealant copes with that without cracking.
Aluminium frames
Large aluminium doors have long joints down each side and across the head, and the bottom joint sees the most water. We prepare and reseal every joint, backing the deep ones.
