For landlords and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
We work for letting agents and landlords as well as householders. Resealing between tenancies is a simple way to keep a property in good order.
Gutter sealing in Canonbie
Open fascia and soffit joints spoil the roofline and can let weather in. They’re sealed in a matching colour where possible. We work on uPVC fascias, gutter joints and garage door frames, and common reasons people get in touch are quick sealant fixes on gutters that didn’t last and failed sealant on a garage door frame.
Across smaller places in Scotland, stone and harled cottages, farm buildings and newer houses often stand exposed to wind and rain. Gutter joints and wall joints take a battering.
Whatever the size of the job, you get the same 12-month guarantee in Canonbie and across Dumfries and Galloway.

The process
When we arrive, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before work begins. The work generally takes anything from an hour or two to a few hours. For a place like Canonbie, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- First we agree which joints need sealing.
- We clean out each joint.
- The joints are dried.
- We apply exterior or gutter sealant and finish it neatly.
- The joints are checked once sealed.

What we cannot put right
New sealant cannot fix everything, and we’d rather say so up front. It will not solve:
- Boards that have decayed or split
- A gutter length that has split
- Leaks from the roof rather than a joint
If you’re not sure, just send an email to info@mrmastic.co.uk and we will give you a straight answer.
What we seal
- uPVC fascias
- Gutter end caps
- Garage door frames
- Gutter joints
- Soffit joints
- Roofline trims
Looking after it afterwards
After the cure time, these simple habits help:
- Get leaks sealed before the wet months
- Watch for drips in a downpour
- Get a dropping gutter looked at quickly
- Glance at the soffit joints now and then
While checking gutters, glance at the fascia joints too. Splits are easier to seal early.
Leaking gutter joints get worse over time. The same spot gets soaked every time it rains, which can lead to staining and damp.
Common problems we fix in Canonbie
Gutter joints depend on seals that wear out. Temperature changes make gutters move and that movement opens up tired joints.
The problems people normally mention when they call are:
- Fascia boards with gaps between them
- Old gutter sealant that has let go
- End caps that drip every time it rains
- Water dripping where gutter sections meet
In the older streets around Canonbie Parish Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Walls and rooflines in Canonbie
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. 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.
Around Canonbie, as everywhere, gutter sealing is only as good as the preparation behind it.

Canonbie: your questions answered
Is gutter sealing in Canonbie guaranteed?
All our work, in Canonbie and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Do you cover Canonbie for gutter sealing?
Yes, Canonbie is within the area we cover. Our work covers the whole of Scotland. You can email us at info@mrmastic.co.uk and tell us what needs doing.
Do you install new fascias or gutters?
We don’t replace gutters or fascias. If a gutter is broken or sagging, we will tell you.
Do you take out the old sealant first?
Yes, every time. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done.
What about gutters on a second or third storey?
It depends on the access. Let us know the height and the ground below when you email us at info@mrmastic.co.uk.
Do I have to be there?
It depends on the job. For work indoors, someone needs to let us in.
Is it worth trying it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
What the job involves on each surface
Roofline trims
Roofline trims rely on sealant at their joints. Split sealant lets water in.
Soffit joints
We choose a sealant colour that suits the soffit, where one is available.
