How we handle gutter sealing in Port Dundas
We work across Port Dundas on leaking gutter joints and roofline trims. Single-storey and low gutters are simple to reach and if it’s higher up, let us know and we’ll confirm what access is needed. Typical jobs include streaks down the brickwork from a leaking joint and old sealant on roofline trims that has split, on gutter end caps, gutter joints and roofline trims.
On a four-storey tenement, gutter joints are a long way from the street, so a leaking joint can run down the stone for months before anyone notices. For a building in Port Dundas, access is planned first, and shared parts may need the other owners to agree.
All our work is covered by our 12-month guarantee, wherever you are in Glasgow.

Questions from Port Dundas
Is Port Dundas in your area for gutter sealing?
Yes. We work across all of Scotland, and Port Dundas is part of that. You can email us at info@mrmastic.co.uk and let us know what needs doing, and we will give you a clear price.
Who arranges sealant work on the shared parts of a tenement in Port Dundas?
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.
Do you work for landlords and businesses?
Yes. We work for householders, landlords, letting agents, businesses and hotels.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Can new sealant go over the old?
No, it will not last. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Do you clean gutters?
The joints we seal are cleaned out and any debris nearby is cleared. Cleaning the whole run is a different job.
Where do you work from?
Mr Mastic is based in Crawley. We cover Port Dundas and the rest of Glasgow.
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Gutter sealing in Port Dundas: local notes
Harled (roughcast) walls are common in Scotland, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
Historic houses such as Tenement House, about 0.7 miles south-west, show how far back building around Port Dundas goes. Managing a site like St Aloysius' College? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Keep ladders off the guttering
- Sort out a dripping joint early
- Don’t leave a sagging gutter
- Check that water runs out of the downpipes
Give the sealant the cure time we tell you before poking or cleaning near it.
A leaking stop end is best sealed before the wet months. A winter of drips can lead to damp patches inside.
When it is not the sealant
We will always be straight with you, so here’s what sealant cannot fix:
- Water backing up from a blocked pipe
- Fascias that need replacing
- Cracked, split or warped gutter sections
If in doubt, email us at info@mrmastic.co.uk and we’ll say what we think before booking.
Joints and surfaces we work on
- uPVC fascias
- Gutter joints
- Soffit joints
- Garage door frames
- Roofline trims
- Gutter end caps
What the job involves on each surface
Gutter end caps
A leaking end cap sends water straight down the wall. It’s a small job to fix.
Roofline trims
Trim joints are cut out and resealed suited to the material.
Common problems we fix in Port Dundas
Roofline sealant ages in sun and rain. It hardens, shrinks and splits after some years.
People normally contact us after spotting one of these:
- Old gutter sealant that has let go
- Cracked sealant along roofline trims
- Damp on an inside wall under a dripping gutter
- Streaks down the brickwork from a leaking joint
Rented homes near Glasgow Queen Street station change hands often, and leaking gutter joints on a rental are best caught before they stain the walls.
Questions to ask before you book
- Whether they’re fully insured
- What happens if they find a problem under the old sealant
- Whether the sealant suits the joint
- When the joint can take water or movement
Why deal with it now?
Leaving a leaking end cap can send water down the wall all winter. Resealing it is a quick job before the damage spreads. For landlords in Port Dundas, damp and leaks can be a Repairing Standard issue, so it’s worth fixing failed sealant before a tenant reports it.
What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts.
