FAQs for Colgrain
I let a flat near Craigendoran station. Can you help?
Yes, rental work is part of what we do. You can email us at info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before we start.
Is Colgrain within the area you cover?
Yes, Colgrain is covered. 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.
Will there be a smell?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
Can new sealant go over the old?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Do you install new fascias or gutters?
That is not something we do. Our work is sealing joints; replacing gutters and fascias needs a gutter or roofline installer.
How do I get a quote for gutter sealing in Colgrain?
It depends on the job, so we quote each one individually. To get one, drop us a line at info@mrmastic.co.uk and let us know what needs doing and where.
Is it possible to stop a gutter joint dripping with sealant?
In many cases, yes. Cleaning, drying and resealing the joint generally works. A split or warped section needs replacing.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.
About our gutter sealing in Colgrain
It’s easy to live with a dripping gutter joint, but the water lands on the same spot every time it rains. Resealing it is a small job if the gutter is otherwise in good order. We work on roofline trims, gutter end caps and soffit joints, and common reasons people get in touch are water dripping where gutter sections meet and damp patches inside below a leaking gutter.
Stone walls need a stone-friendly sealant, as acetoxy products can attack some stone. On newer homes, the movement joints and roofline trims are what need watching.
There’s a 12-month guarantee on every job, whatever its size.

What else we do in Colgrain
What happens on the day
We bring everything the job needs with us, so you do not need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. Most jobs take an hour or two for a few joints, longer for a full run. For a place like Colgrain, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We start by tracing the leak and checking the gutter itself is sound.
- The joint or trim is cleaned out and old sealant removed.
- The joint is dried, because sealant will not bond to a wet surface.
- Gutter or exterior sealant is applied and finished.
- We look along the gutter and clear debris around the joints.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Where the joints are inside, avoid wetting them before we arrive
- Mention if the joints have been sealed before

Outside joints around Colgrain
Colgrain is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on gutter, fascia and roofline joints, which can dry out and crack sooner where a building faces the weather. With historic houses such as Hill House (about 2.7 miles north-west) nearby, there’s older building stock in the area around Colgrain as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
If you look after a building such as Hermitage Academy, its movement joints, gutters and trims need looking after like any other building’s. Rented homes near Craigendoran station change hands often, and a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.

Surface by surface
Roofline trims
Sealing roofline trims is joint work only. Roofing problems need a roofer.
Gutter end caps
End caps take the pressure of water running along the gutter. When their seal fails, they drip.
Signs you need gutter sealing in Colgrain
Roofline sealant ages in sun and rain. It goes hard, cracks and pulls away over time.
Look out for any of the following:
- End caps that drip every time it rains
- Old sealant on roofline trims that has split
- Rain getting in around a garage door
- Fascia boards with gaps between them
Hill House, about 2.7 miles north-west, is one of the historic houses in the wider area around Colgrain.

Quotes for gutter sealing in Colgrain
The quote reflects the job in front of us. We look at:
- Whether there’s mould to deal with
- How much old sealant there is and how hard it is to remove
- How many areas need sealing
- Which sealant suits the joint
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.
Asking for a quote
Before you ask for a quote, have a think about:
- Any previous sealing or DIY work
- Roughly how big the job is
- Photos by email, if that’s easy
- Whether it’s a home or a business
Call for a quick quote, or email us if that is easier. Describe what needs sealing and we’ll talk you through the work before giving you a price.
Can I do it myself?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Looking after it afterwards
To keep the joints looking good and working properly:
- Get leaks sealed before the wet months
- Keep ladders off the guttering
- Keep downpipes clear
- Look for streaks or damp on the wall below gutters
Clear the gutters once or twice a year, so water drains away past the joints. Standing water strains every seal.
A leaking garage frame lets water reach stored items. Resealing the frame is a quick job.
Leave it or put it right?
Leaving a leaking end cap can send water down the wall all winter. It’s a small job to put right compared with treating damp later. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
We don’t 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.
