How we handle window mastic in Croftfoot
Around Croftfoot we seal all kinds of frames: from uPVC casements to timber and aluminium, along with patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. We’re often asked to deal with mastic that’s falling out in pieces and gaps between the frame and the inside reveal, on aluminium frames, patio & French doors and window sills.
Croftfoot is in one of Scotland’s four big cities, where many older buildings are sandstone or granite. Stone needs a sealant that suits it, which normally means a neutral-cure product or a traditional sand mastic rather than an acetoxy silicone.

Surface by surface
Composite doors
Composite doors are normally hung in an uPVC-type frame, so its perimeter joint is sealed much like a window. We match the colour to the frame.
uPVC windows
The frame is cleaned with a product that will not harm the plastic, then the new bead is laid against the frame and the wall.

FAQs for Croftfoot
Do you cover Croftfoot for window mastic?
Yes. We work across all of Scotland, and Croftfoot is part of that. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing, and we will send you a clear quote.
How is work on the outside of a tenement in Croftfoot normally arranged?
Most tenements arrange shared repairs through the owners or a property factor. The Tenements (Scotland) Act 2004 covers the common parts where the deeds don’t, and we can quote for the factor or the owners directly.
Can tenants book the work?
We can work for tenants, landlords or agents. Get your landlord’s agreement first.
Where is Mr Mastic based?
We are a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Do you work on first-floor 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.
Is there any odour?
It depends on the product. Some products have a noticeable smell, others very little.
Can you do several jobs on one visit?
Yes. More than one area can go on one quote.
Can I paint over the new sealant?
That depends on the product. Some hybrid sealants can be painted; silicone cannot. Tell us if you’re decorating and we’ll choose accordingly.
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Ventilate rooms so frames do not stay wet inside
- Don’t paint over the silicone
- Make sure the drainage slots are not blocked
- Avoid harsh chemicals near the mastic
Clean the frames with mild soapy water, and avoid solvent cleaners on the sealant.
A failed joint lets water into the wall a little at a time. You might not see it until plaster blows or a damp patch appears inside. Catching it early keeps the fix to a reseal.
What sealant work cannot fix
Some problems need a builder, plumber or other trade rather than us:
- A door that needs adjusting, rehanging or new seals
- Penetrating damp from a failed cavity tray or render
- A frame that has rotted at the joint
If you are not sure, just email us at info@mrmastic.co.uk and we’ll give you a straight answer.

Frames and glazing around Croftfoot
Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic. Under the Tenements (Scotland) Act 2004, shared parts of a tenement, such as the roof and outside walls, are looked after by the owners together, often through a property factor. Who owns the windows depends on the title deeds.
Provand's Lordship, about 3.4 miles north, is one of the historic houses in the wider area around Croftfoot, and older homes nearby need a sealant that suits their walls. For landlords with property near Croftfoot station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. Schools such as St Margaret Mary's Secondary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

- The type of sealant required
- Any working-time requirements on site
- How many areas need sealing
- Access and height
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part.
What we need to know
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- Any access issues, like height or stairs
- Pictures of the joints, sent by email

Why deal with it now?
A cracked joint around a frame lets rain into the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. Resealing now is a small job by comparison. In a tenement flat in Croftfoot, a failed seal is rarely just your problem: 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 each job is priced on what it involves. Call for a quick quote and we will talk you through it.
