Window mastic for homes and businesses in Kingsknowe
If you can feel air around a shut window, the gap is often at the frame. A new joint stops the air getting through and quietens the whistle on windy days. If the draught is through the window seals instead, we will tell you. We work on aluminium frames, window sills and composite doors, and people most often call us about whistling draughts around closed windows and untidy mastic left by window fitters.
Sash and case windows are a feature of older tenements in all four Scottish cities, though many have since been replaced. In Kingsknowe, as anywhere, the mastic between frame and wall is what stops draughts and rain getting in.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

Signs you need window mastic in Kingsknowe
Some failures date back to when the windows were fitted. Sealant run over dust, wet brick or loose mortar never bonded as it should, and it lets go sooner than it should.
Signs it’s time to call us include:
- Sealant in the wrong colour for the frame
- Old mastic that has gone black or come away
- Cracked sealant at the sill ends
- Draughts coming in around windows and doors
For landlords with property near Kingsknowe station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Questions from Kingsknowe
How is work on the outside of a tenement in Kingsknowe normally arranged?
The owners of the flats generally agree repairs to shared parts like the roof and outside walls, and many buildings have a factor to arrange it. Where the title deeds are silent, the Tenements (Scotland) Act 2004 fills the gaps. Your title deeds will say who owns the windows.
I let a flat near Kingsknowe station. Can you help?
Yes, we work for landlords and agents. You can drop us a line at info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before any work starts.
Do you seal inside as well as outside?
Yes. Outside is the weather seal; inside closes the gap to the plaster. We can do either or both.
Are you insured?
Yes. We are fully insured, and we’ve been doing sealant work for more than 20 years.
How much does window mastic cost in Kingsknowe?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
How long does it take to reseal the windows on a house?
It depends on access, the old mastic and the size of the frames. You will know the timing when we quote.
Is it OK to seal over old sealant?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
What happens if it’s left?
The work is quick compared with the damage it prevents: it takes most of a day for a typical house, less for a few frames. Wait for damp to appear and there may be plaster and decorating to sort out too. In a Scottish city tenement, failed sealant affects more than one flat: a leak can come through the ceiling below, and gaps in shared walls or fire-rated joints matter to every flat.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please email us at info@mrmastic.co.uk.

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
What affects the quote in Kingsknowe
There’s no set price list. The quote depends on:

What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and give you a clear price before we start.
