Why act early in Blackford
The work is quick compared with the damage it prevents: the visit takes a morning for a couple of windows and a door. Leave it until water is coming in and you may need plastering and decorating as well. In a place like Blackford, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.

Window mastic in Blackford, done properly
From a single sill to a whole house of windows, the work is priced before anything is done. To get one, drop us a line at info@mrmastic.co.uk with the number of frames and any access details. If you have a bead that doesn’t match the frame and cracked internal joints between frame and plaster, we can help.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
You’re covered for a year from the day we finish. If anything is not right with it, drop us a line at info@mrmastic.co.uk.

What affects the cost of window mastic
You’ll get a clear quote before we start. It takes into account:
- The number and length of the joints
- How easy the joints are to reach
- The old material and how stubborn it is
- Whether there’s mould to deal with
A few things move the cost up or down: 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.
Asking for a quote
Photos by email are helpful but not essential. Try to tell us:
- Any access issues, like height or stairs
- Photos by email, if that is easy
- Roughly how big the job is
- If it’s domestic, commercial or a hotel
It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll talk you through what we’d do. When it suits you, send an email to info@mrmastic.co.uk.
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Ventilate rooms so frames don’t stay wet inside
- Walk round the house once a year and look at the joints
- Keep paint and stain on wooden frames in good order
- Keep paint off silicone joints
Most silicone sealants won’t take paint, so if you’re planning to paint the frames or walls, tell us beforehand. We can use a paintable sealant where that matters.
Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. Resealing closes it.
Frames and glazing around Blackford
Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
Around Blackford, as everywhere, window mastic is only as good as the preparation behind it.

Should I try it myself first?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Blackford questions
Do you cover smaller places like Blackford?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Can you do window mastic in Blackford?
Yes. We work across all of Scotland, and Blackford is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job.
Can new sealant go over the old?
No. We remove every bit of old sealant first.
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.
What should I tell you?
Only a few details: the address or postcode, what’s wrong and any access issues. Then email us at info@mrmastic.co.uk.
Can I add another job to the visit?
Yes. Just list everything you need.
Can you do the inside joint as well?
Yes. Draughts often come through the inside gap too, so it can be worth sealing both.

Yes. We work in offices, washrooms, hotels and other commercial premises. We can talk about working times when we quote.
How the visit works
You don’t need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the work takes a few hours for a few frames, or a day or more for a whole house for a typical job. Around Blackford, distance and access matter more than parking. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.

- Every joint is tooled smooth and checked before we leave.

How the job changes by surface
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A tidy bead in anthracite grey, black or a matching colour keeps the clean look.
Composite doors
Draughts round the door leaf generally come from worn seals or adjustment, not the mastic. We seal the frame and let you know about anything else.
Common problems we fix in Blackford
Joint shape matters as much as the product. A skim of sealant over a wide gap soon tears, while a joint packed solid cannot stretch. That’s what backing rod is for.
These are the problems we’re asked about most:
- Cold air getting in at the frame edge
- Cracked sealant at the sill ends
- Cracked or shrunken mastic around the frame
- Black, perished sealant on frames
If you let a flat or house near Gleneagles station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
