Gutter sealing for homes and businesses in Thankerton
A lot of gutter leaks come down to one tired joint. The joint is cleaned, dried and resealed with a sealant made for guttering. If the gutter itself has failed, we say so. We work on roofline trims, gutter end caps and garage door frames, and common reasons people get in touch are failed sealant on a garage door frame and dripping gutter ends.
In and around a place like Thankerton, many buildings face open ground and take the full weather. Outside joints on exposed walls work hard, so they need a sealant that moves with the building.

Your questions about gutter sealing in Thankerton
Do you cover smaller places like Thankerton?
Yes, we do. We work across all of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
I let a flat near Carstairs station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners. You can email us at info@mrmastic.co.uk with the details for a clear quote.
Will there be a smell?
There can be a smell while the sealant cures. Opening a window helps.
Are you ARBOMaster approved?
Yes. We are approved under the ARBOMaster scheme.
Do you replace gutters or fascias?
No. We seal joints and replacement is a job for an installer.
Can I do it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
What does gutter sealing cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we will talk you through it.
Will sealing fix a sagging gutter?
Not on its own. A sagging gutter pulls its joints apart, so the brackets need fixing first.
Walls and rooflines in Thankerton
Plenty of Scottish homes have harled walls, 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.
For an older house near a landmark such as Covington Parish Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Leave it or put it right?
Sealant won’t clear a blocked downpipe. We check the cause first and point you to the right trade if needed. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
The cost depends on the amount of work, how hard the old material is to remove and access to the work. We give a clear quote before we start.

When to call us in Thankerton
Stop ends take pressure from water running along the gutter. If the seal fails, water escapes at the end.

- Old gutter sealant that has let go
- Garage door frames letting rain in

Letting a property close to Carstairs station? Then a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Keep the gutters clear of debris
- Do not leave a sagging gutter
- Sort out a dripping joint early
- Look at the gutters while it’s raining
Check the joints after heavy rain now and then. It’s the easiest time to see a leak.
Early sealing limits how much water hits the wall. If we find a bigger problem, we’ll tell you.

What we do, step by step
You don’t need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the job takes anything from an hour or two to a few hours for a typical job. Around Thankerton, distance and access matter more than parking. Tell us how to find the property and how to reach the work.
- First we trace the drip and check the gutter isn’t damaged.
- The old sealant and dirt are cleaned out of the joint.
- The joint is dried before sealing.
- We seal the joint with a sealant made for gutters.
- We check the run and clear debris near the joints.
