Gutter sealing in Mochrum, done properly
For gutter sealant to hold, the joint has to be clean and dry. That is why we take out the old sealant and dirt first and the joint is dried before the new sealant goes in. We are often asked to deal with fascia boards with gaps between them and internal damp traced to a gutter joint, on garage door frames, roofline trims and gutter end caps.
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, so they need a sealant that moves with the building.
Our work is backed for twelve months, in Mochrum and everywhere else we cover.

DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What gutter sealing looks like in Mochrum
Mochrum is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on gutter, fascia and roofline joints, which can dry out and crack sooner where a building faces the weather. 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.
In and around Mochrum, as anywhere, good gutter sealing starts with a clean, dry, properly prepared joint.

Common questions in Mochrum
Do you cover smaller places like Mochrum?
Yes, we do. We work across all of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Does living near the coast affect gutter sealing in Mochrum?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Are you insured?
Yes. We are fully insured.
Is it messy?
Tidy work is part of the job. We protect what’s around the joints.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
Will you clear out my gutters?
We clean the joints we are sealing and any debris nearby is cleared. A full gutter clean is a separate service.
Can you do several jobs on one visit?
Yes. Just list everything you need and we will quote it together.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
How it works
We keep the work tidy and contained to the area we’re working on. The job usually takes a few hours, depending on the number of joints and the access. In smaller Scottish places, parking is usually less of an issue than access and distance. 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 will not bond to a wet surface.
- Gutter or exterior sealant is applied and finished.
- We check the run and clear any debris we find while we are there.
Before we arrive
- Tell us about any water getting in
- Clear items away from the joints we are working on
- Tell us about access, such as stairs, a lift or high-level joints

For gutter sealing in Mochrum, send an email to info@mrmastic.co.uk. Tell us what the problem is and where, and we will agree the price before any work begins.
What we cannot put right
New sealant cannot fix everything, and we’d rather say so up front. Sealant won’t put right:
- Leaks from the roof rather than a joint
- Sagging gutters or broken brackets
- Water backing up from a blocked pipe
If you are not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer.
Joints and surfaces we work on
- Roofline trims
- Gutter end caps
- Gutter joints
- Garage door frames
- uPVC fascias
- Soffit joints
Common problems we fix in Mochrum
Roofline sealant ages in sun and rain. It hardens, shrinks and splits after some years.
Common reasons people contact us are:
- Internal damp traced to a gutter joint
- Streaks down the brickwork from a leaking joint
- Garage door frames letting rain in
- Earlier gutter repairs that have peeled off
Homes close to Kirk of Mochrum include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.
Questions to ask before you book
