Gutter sealing for homes and businesses in Cowlairs
For gutter sealant to hold, the joint has to be clean and dry. That’s why we take out the old sealant and dirt first and the joint is dried before the new sealant goes in. We work on roofline trims, gutter joints and gutter end caps, and the jobs we see most are rain getting in around a garage door and end caps that drip every time it rains.
In a Scottish city tenement, the roof, gutters and outside walls are shared by all the flats. In Cowlairs, work on shared parts of a tenement is generally agreed between owners, often with a factor arranging it.
All our work comes with a 12-month guarantee, wherever you are in Glasgow.

Common questions in Cowlairs
Do you work for landlords with property near Ashfield station?
Yes, rental work is part of what we do. Just drop us a line at info@mrmastic.co.uk and tell us about the property, and we will give you a clear price.
Who arranges sealant work on the shared parts of a tenement in Cowlairs?
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.
How much does gutter sealing cost in Cowlairs?
It depends on the job, so we quote each one individually. To get one, drop us a line at info@mrmastic.co.uk and tell us what needs doing and where.
Can you seal over the old sealant?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. We remove it all first.
Do you clean gutters?
We clean the joints we are sealing and clear debris we find nearby. A full gutter clean is a separate service.
Will sealing fix a sagging gutter?
Sealing a sagging joint will not last. The gutter needs refixing by a gutter installer.
Do you have insurance?
Yes. We’re fully insured, and we’ve been doing sealant work for more than 20 years.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access.

What else we do in Cowlairs
How the job changes by surface
uPVC fascias
Open fascia joints look untidy and can let water in. A neat bead closes them up.
Gutter end caps
End caps are resealed where they meet the gutter once clean and dry.
Leave it or put it right?
Water from a leaking joint hits the same spot every time. Left, it can stain walls and lead to damp so early sealing is worthwhile. For landlords in Cowlairs, damp and leaks can be a Repairing Standard issue, so it’s worth fixing failed sealant before a tenant reports it.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and send you a clear quote before any work starts.

What gutter sealing looks like in Cowlairs
Glasgow’s tenements are largely red and blond sandstone, and porous sandstone needs a sealant that won’t mark it. Cowlairs is in the west of Scotland, which is wetter than the east, which means gutter, fascia and roofline joints has to cope with a lot of rain.
Historic houses such as Tenement House, about 1.4 miles south-west, show how far back building around Cowlairs goes. For site and facilities teams at buildings such as St. Roch's Secondary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Letting a property close to Ashfield station? Then a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside.

Should I try it myself first?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Clear leaves and moss from the gutters
- Sort out a dripping joint early
- Watch for drips in a downpour
- Make sure downpipes are not blocked
Clear the gutters once or twice a year so water doesn’t sit on the joints. Water left in a gutter tests every joint.
A drip from a gutter joint won’t stop on its own. Water keeps hitting the same part of the wall, which can lead to staining and damp.
