What affects the cost of gutter sealing
We quote each job individually. These are the things that affect it:
- The number and length of the joints
- The old material and how stubborn it is
- Whether there’s mould to deal with
- Working hours on commercial sites
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
What to tell us for a quote
Photos help, but a description is a good start. Try to tell us:
- Access, such as stairs, a lift or height
- Any previous sealing or DIY work
- Whether it’s a home or a business
- The problem you’ve noticed
We don’t publish a price list, because every job is different. Instead, we give you a clear price for your job. To get started, email us at info@mrmastic.co.uk.
About our gutter sealing in Monreith
Many dripping gutters are just a failed joint or end cap. The joint is cleaned, dried and resealed with a sealant made for guttering. If the gutter itself has failed, we say so. We’re often asked to deal with quick sealant fixes on gutters that didn’t last and damp on an inside wall under a dripping gutter, across gutter end caps, uPVC fascias and soffit joints.
In and around a place like Monreith, many buildings face open ground and take the full weather. Gutter joints and wall joints take a battering, so they need a sealant that moves with the building.
All our work comes with our one-year guarantee.

What gutter sealing looks like in Monreith
Monreith is within about 1 mile of 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. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
In and around Monreith, as anywhere, good gutter sealing starts with a clean, dry, properly prepared joint. Whether the job is in Monreith itself or nearby, the right material for each joint matters as much as a neat finish.

Other services in Monreith
Should I try it myself first?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Your questions about gutter sealing in Monreith
Does living near the coast affect gutter sealing in Monreith?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. Walls facing the sea are usually the first to need attention.
Will you come out to Monreith?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Will you clear out my gutters?
The joints we seal are cleaned out and clear debris we find nearby. Cleaning the whole run is a different job.
Do you take out the old sealant first?
Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Do you replace gutters or fascias?
That’s not something we do. We seal joints; replacing gutters and fascias needs a gutter or roofline installer.
Do the sealants smell?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
Are you fully insured?
Yes. Mr Mastic is fully insured, and we have been doing sealant work for more than 20 years.
Which products do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We will tell you what we’re using and why.

How the visit works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours, depending on the number of joints and the access. Around Monreith, 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.
- We make sure the joint is dry before sealing.
- Gutter or exterior sealant is applied and finished.
- We look along the gutter and clear debris around the joints.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Tell us about access, such as stairs, a lift or high-level joints
- On commercial sites, let us know about site rules

What we cannot put right
A few problems are outside what sealant work can do:
- Rotten or damaged fascia boards
- Brackets that have snapped or loosened
- Water backing up from a blocked pipe
If in doubt, email us at info@mrmastic.co.uk and we’ll say what we think.
Where we work in Monreith
- Gutter joints
- Gutter end caps
- Soffit joints
- Roofline trims
- Garage door frames
- uPVC fascias
What happens if it’s left?
Sealant won’t clear a blocked downpipe. We look at what’s really happening and tell you if something else is needed. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part.
