Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
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.
Gutter sealing in Scottish Borders
Garage door frames let rain in when the sealant around them fails. The frame joint is cut out and resealed with an exterior sealant. If you are dealing with streaks down the brickwork from a leaking joint and internal damp traced to a gutter joint, we can put it right, on roofline trims, gutter end caps and garage door frames alike.
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.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

What we do, step by step
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, do the work and clear up. Most jobs take a few hours, depending on the number of joints and the access. Around Scottish Borders, distance and access matter more than parking. Tell us how to find the property and how to reach the work.
- We start by tracing the leak and checking the gutter itself is sound.
- Old sealant and dirt are removed from the joint.
- The joint is dried, because sealant won’t bond to a wet surface.
- Gutter or exterior sealant is applied and finished.
- The run is checked and any debris near the joints is cleared.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Mention any sign-in or site rules at work premises
- Tell us if parking is tricky

Is gutter sealing in Scottish Borders guaranteed?
All our work, in Scottish Borders and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Will there be a smell?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is generally more efficient.
Will you clear out my gutters?
The joints we seal are cleaned out and any debris nearby is cleared. Cleaning the whole run is a different job.
Will sealing fix a sagging gutter?
No. A sagging gutter pulls its joints apart, so the brackets need fixing first.

Gutter sealing in Scottish Borders: local notes
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. 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.
For an older house near a landmark such as Tweedsmuir Parish Church, an extension built onto an older house moves differently, and the joint between them takes the strain. In and around Scottish Borders, as anywhere, good gutter sealing starts with a clean, dry, properly prepared joint.

Joints and surfaces we work on
- Gutter joints
- Gutter end caps
- Roofline trims
- Soffit joints
- Garage door frames
- uPVC fascias
Aftercare tips
Looking after new joints is easy:
- Check that water runs out of the downpipes
- Sort out a dripping joint early
- Look along the fascias for open joints
- Rest ladders on the wall, not the gutter
Give the sealant the cure time we tell you before poking or cleaning near it.
Early sealing limits how much water hits the wall. We’ll let you know if the gutter needs more than sealant.
Different surfaces, different methods
Gutter end caps
End caps take the pressure of water running along the gutter. A failed seal makes them leak.
Soffit joints
Gaps at soffit joints can let in draughts and insects. A neat seal closes them.
How we quote for gutter sealing
The price is agreed before any work begins. It takes into account:
- The size of the job
- Access and height
- How many rooms, windows or areas are involved
- Any mould that needs treating
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.
What to tell us for a quote
To make quoting easier, please include:
- Whether it’s a home or a business
- What the problem is, such as mould, gaps, leaks or cracking
- Any access issues, like height or stairs
- The address or postcode of the job
There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, send an email to info@mrmastic.co.uk.

Why it’s worth doing now in Scottish Borders
Sealing over a dirty, wet joint is a quick fix that rarely lasts, but it soon lets go. Proper preparation is the difference. Around Scottish Borders, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please drop us a line at info@mrmastic.co.uk.
