Sealing leaking gutter joints, end caps, fascias, soffits and roofline trims for householders, landlords and businesses in Arrochar. Fully insured, ARBOMaster approved and guaranteed for a year.

- Garage door frames letting rain in
Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Gutter sealing in Arrochar
Many dripping gutters are just a failed joint or end cap. We clean out the joint, dry it and reseal it using a gutter sealant. If the gutter itself has failed, we say so. If you are dealing with rain getting in around a garage door and end caps that drip every time it rains, we can put it right, whatever the surface.
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.
A 12-month guarantee comes as standard, so you’re covered after we have gone.

Common questions in Arrochar
Can you help a landlord with a rental near Arrochar & Tarbet station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can drop us a line at info@mrmastic.co.uk with the details for a clear quote.
Is Arrochar within the area you cover?
Yes, Arrochar is covered. Our work covers the whole of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Will sealing fix a sagging gutter?
It won’t last. The joint will pull apart so the gutter has to be refixed first.
How long does the job take?
As a guide, most jobs take an hour or two for a few joints, longer for a full run. Larger jobs naturally take longer.
Will sealant fix a dripping gutter joint?
Most of the time. If the gutter is sagging or cracked, sealing will not last, and we’ll tell you.
Can you fit new guttering?
No, we reseal joints and trims. Replacement needs a gutter installer or roofer.
Where are you based?
We work from Crawley. We cover Arrochar and the rest of West Dunbartonshire, along with the rest of our area.
Do you guarantee gutter sealing?
Our one-year guarantee covers every job.

What affects the cost of gutter sealing
The price is agreed before any work begins. It’s based on:
- Working hours on commercial sites
- Which sealant suits the joint
- Access and height
- How many rooms, windows or areas are involved
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Helping us quote
When you contact us, it’s useful to know:
- If it’s domestic, commercial or a hotel
- Whether it has been sealed before
- Photos by email, if that is easy
- Access, such as stairs, a lift or height
Asking for a quote is easy: let us know the job and the location. A few photos by email make the job easier to understand.
What happens on the day
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take an hour or two for a few joints, longer for a full run. In smaller Scottish places, parking is generally less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- First, we find the drip and check the gutter is not cracked or sagging.
- 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 check the run and clear any debris we find while we’re there.
Before we arrive
- Mention any sign-in or site rules at work premises
- Clear items away from the joints we are working on
- Tell us about any previous sealing or DIY attempts

Advice
Walls and rooflines in Arrochar
Arrochar 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. Arrochar is in the west of Scotland, which is wetter than the east, which means gutter, fascia and roofline joints has to cope with a lot of rain.
If you live in an older home near Arrochar Church, an extension built onto an older house moves differently, and the joint between them takes the strain.

Keeping the joints in good condition
After the cure time, these simple habits help:
- Have sagging gutters refixed early
- Watch the wall under the gutters for staining
- Glance at the soffit joints now and then
- Keep the gutters clear of debris
Give the sealant the cure time we tell you before poking or cleaning near it.
A leaking stop end is best sealed before the wet months. Water down the wall all winter can cause damp inside.
When to call us in Arrochar
Water spilling over a blocked gutter is often mistaken for a leak. If the downpipe is blocked, water has nowhere to go, which is why we look before we seal.
