FAQs for Blackhill
Who arranges sealant work on the shared parts of a tenement in Blackhill?
It generally goes through the owners together, or through the factor if the building has one. The Tenements (Scotland) Act 2004 covers the common parts where the deeds do not, and we can quote for the factor or the owners directly.
Do you work for landlords with property near Alexandra Parade station?
Yes, we work for landlords and agents. You can email us at info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before work begins.
Will there be a smell?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
What do you need from me for a quote?
A short description and the location, with pictures by email if possible. If we need more, we’ll ask.
What guarantee do I get?
Our 12-month guarantee applies on all our work.
Do you hold any approvals?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
What sealant do you use on glazing?
Glass needs a sealant made for glazing. We use neutral-cure glazing silicone and anti-fungal silicone in wet areas.
How long does the job take?
That depends on the amount of work, but as a guide it takes a few hours for most jobs. We’ll give you a better idea when we quote.
About our glazing silicone in Blackhill
We renew glazing silicone on conservatories, rooflights and glass panels, as well as frameless shower screens and glass balustrade bases. The old sealant comes out, the joint is cleaned and new silicone goes in. We’re often asked to deal with shower screens leaking along the wall or tray and glazing silicone that has cracked or come away, across glass balustrade bases, shower screens and conservatory frames.
Blackhill is in one of Scotland’s four big cities, where many older buildings are sandstone or granite. Natural stone around older windows needs a sealant that will not mark or attack it, which usually means a neutral-cure product or a traditional sand mastic rather than an acetoxy silicone.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

How the job changes by surface
Glass balustrade bases
Glass balustrades sit in a channel that is often finished with sealant. When it fails, water can sit in the channel.
Rooflights
Water around a rooflight isn’t always the sealant. We check which it is.
What we are called out for in Blackhill
UV light ages silicone and roof joints get the most sun. Old silicone hardens, cracks and loses its grip on the glass.
The most common problems we see are:
- Conservatory leaks at frame and glazing joints
- Mouldy sealant around glass panels
- A quick top-up bead that didn’t last
- Shower screens leaking along the wall or tray
If you let a flat or house near Alexandra Parade station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.
Questions to ask before booking
- Which colour the sealant will be
- The length of the guarantee
- What the cure time is
- Whether all the old sealant comes out first

DIY sealant or a professional job?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Frames and glazing around Blackhill
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. Historic houses like Provand's Lordship (about 1.7 miles south-west) are a reminder that the area around Blackhill has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Historic houses such as Provand's Lordship, about 1.7 miles south-west, show how far back building around Blackhill goes.

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Stick to mild cleaners on glass
- Avoid strong solvents on or near the sealant
- Open vents or windows to let moisture out
- Run a squeegee over the glass when you’re done
Keep the new joints dry for as long as we advise. After that, clean glass with a mild cleaner.
Cracked glazing silicone means the joint has failed. Renewing it early keeps it simple compared with fixing water damage later.
