About our window mastic in Barmulloch
Over two decades of sealing frames has taught us which products suit which walls. We are fully insured ARBOMaster approved applicators, and we give a one-year guarantee on the work. If you’re dealing with gaps between the frame and the inside reveal and rain getting in at the frame or under the sill, we can put it right.
Tenement flats in Scotland’s cities often have windows high above the street, where failing mastic is easy to miss. For a flat in Barmulloch, access is the first thing to plan, and in a tenement the outside of the building may be a shared repair.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

- Faulty window hardware
- Penetrating damp from a failed cavity tray or render
- Soft or decayed wood in the frame
Not sure which it is? You can email us at info@mrmastic.co.uk and we’ll tell you honestly before you book.

Why act early in Barmulloch
Running fresh sealant over the old joint is tempting, but it won’t grip old, dirty sealant. It soon lifts and the leak carries on behind it. Proper resealing starts with removing the old joint. For landlords in Barmulloch, damp and leaks can be a Repairing Standard issue, so it’s worth fixing failed sealant before a tenant reports it.
Combining jobs into one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear quote for the lot.

Do you need window mastic in Barmulloch?
On timber frames, paint and putty build up around the joint. Old mastic gets painted over and cracks under the paint, and the wood moves with damp as well as heat.
If you can see any of these, it’s time to have the joints looked at:
- Whistling draughts around closed windows
- Gaps where the sill meets the wall
- Cracked internal joints between frame and plaster
- Mastic that has split away from the wall
Letting a property close to Barnhill station? Then renewing tired window mastic between tenants heads off draught and damp complaints.
What your quote should include
- What happens if they find a problem under the old sealant
- What insurance they hold
- Which colour the sealant will be
- Is the old sealant removed completely?
Common questions in Barmulloch
Do you cover Barmulloch for window mastic?
Yes. We work across all of Scotland, and Barmulloch is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we will give you a clear quote.
Who arranges sealant work on the shared parts of a tenement in Barmulloch?
Shared parts of a tenement, such as the roof and outside walls, are generally repaired with the agreement of the owners, often through a property factor. Where the title deeds are silent, the Tenements (Scotland) Act 2004 fills the gaps. Windows often belong to the individual flat, but it’s worth checking your deeds.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. We cover Barmulloch and the rest of Glasgow, along with the rest of our area.
Will you leave a mess?
We keep the work tidy. We protect what’s around the joints, and we clear up when we are done.
Can you do upstairs windows?
Yes, where they can be reached safely. Let us know about access when you ask for a quote and we’ll plan for it.
Will new mastic stop draughts?
Yes, if the air is getting in around the frame. If it’s through the window’s own seals or a hinge, that’s a different fix, and we will say so.
What information do you need?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
Can landlords and businesses book you?
Yes, we do. We work in homes, commercial premises and hotels.
Can I do it myself?
A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
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.
Barmulloch homes and the weather
The Tenements (Scotland) Act 2004 sets out how owners share the upkeep of common parts like the roof and outside walls, and many buildings use a factor to arrange it. Who owns the windows depends on the title deeds. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.

What affects the quote in Barmulloch
We do not publish a price list. The quote depends on:
- Whether there’s mould to deal with
- Access and height
- The number of rooms or windows
- The type of sealant required
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
Helping us quote
You do not need to know the technical terms. It helps if you can tell us:
- If it’s domestic, commercial or a hotel
- The rough size of the job
- Any previous sealing or DIY work
- Where the property is
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.
Looking after it afterwards
To keep the joints looking good and working properly:
- Avoid harsh chemicals near the mastic
- Clean frames with a soft cloth and soapy water
- Paint up to the joint, not over it
- Keep jet washers away from the mastic
Wipe the frames with soapy water when you clean the windows, and keep solvents and harsh chemicals off the joint.
On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so it pays to reseal before that happens.
