Gutter sealing in Dennistoun
Gutter and fascia replacement isn’t our trade, and nor is roofing. Sealant fixes joints; it won’t fix a broken bracket, a cracked section or a blocked downpipe. We work on soffit joints, roofline trims and garage door frames, and the jobs we see most are water dripping where gutter sections meet and old gutter sealant that has let go.
Scotland’s cities also have plenty of modern blocks with rendered or clad walls and sealed movement joints. Around Dennistoun, as anywhere, those joints dry out and crack over time, letting water behind the face of the building.
You get a 12-month guarantee, the same in Dennistoun as everywhere else we work.

Dennistoun: your questions answered
How do repairs to the shared parts of a tenement in Dennistoun get organised?
It normally goes through the owners together, or through the factor if the building has one. The Tenements (Scotland) Act 2004 sets the rules for common parts if the deeds don’t.
Can you help a landlord with a rental near Duke Street station?
Yes, rental work is part of what we do. 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 work begins.
Can you work on commercial sites?
Yes. We’ve worked for hotels, offices and other businesses and we’re fully insured.
Where is Mr Mastic based?
We work from Crawley. We cover Dennistoun and the rest of Glasgow.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
How long will you be here?
That depends on how much there is to do, but as a guide it takes anything from an hour or two to a few hours. We’ll tell you when we quote.
Does someone need to be in?
That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Is sealant enough for a gutter that has dropped?
Not for long. The movement opens the joint again so the gutter has to be refixed first.
What we do, step by step
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes an hour or two for a few joints, longer for a full run and we leave things clean and tidy. In a city area like Dennistoun, parking may be by permit or pay-and-display, so tell us what’s nearby. For flats, mention the door entry system and any shared-stair arrangements.
- We look at the gutters, fascias and trims and agree the joints to seal.
- We clean out each joint.
- We make sure everything is dry.
- We apply exterior or gutter sealant and finish it neatly.
- The joints are checked once sealed.
Before we arrive
- Let us know about stairs, lifts or work at height
- Move anything stored near the joints
- Plan for the work area to be out of bounds to pets and children

What the job involves on each surface
Garage door frames
A fresh seal around the frame stops rain getting in.
Roofline trims
Trim joints are cut out and resealed.
Walls and rooflines in Dennistoun
Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex. Much of Glasgow is built from red and blond sandstone, and sandstone is porous, so any sealant against it has to be one that won’t stain or attack it.
If you live in an older home near Rutherford Church, the joints between older walls, newer extensions and the roofline need a sealant that can move. Schools such as Whitehill Secondary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.

Why it’s worth doing now in Dennistoun
Sealant won’t clear a blocked downpipe. We check the cause first and tell you if something else is needed. Private landlords in Dennistoun must meet the Repairing Standard, and damp or leaks can fall short of it, so it’s worth fixing failed sealant before a tenant reports it.
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and agree the price before starting.

How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Check the gutters during heavy rain
- Deal with a drip before winter
- Look for streaks or damp on the wall below gutters
- Rest ladders on the wall, not the gutter
Make sure downpipes aren’t blocked, so water can get away. A blocked pipe backs water up to the joints.
Split sealant on fascias and trims lets water in behind. Sealing it early keeps the boards behind dry and the wall below.

What sealant work cannot fix
New sealant cannot fix everything, and we will tell you before any work starts. It won’t solve:
- Leaks from the roof rather than a joint
- Sagging gutters or broken brackets
- A gutter length that has split
If in doubt, email us at info@mrmastic.co.uk and we’ll say what we think.
