We cover Shandon for sealing leaking gutter joints, end caps, fascias, soffits and roofline trims. Old material cut out, joints cleaned and sealed neatly.
- Dripping gutter ends
- Rain getting in around a garage door
- Water running down the wall below the gutter
How it works
All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours, depending on the number of joints and the access. Somewhere like Shandon may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- We start by tracing the leak and checking the gutter itself is sound.
- We clean out the joint and take out the old sealant.
- We make sure the joint is dry before sealing.
- An exterior or gutter sealant is applied to the joint.
- We check the run and clear any debris we find while we are there.

Gutter sealing for homes and businesses in Shandon
A leaking gutter joint marks the wall and wets the ground underneath. Often a reseal is enough if the gutter is not damaged. Typical jobs include damp patches inside below a leaking gutter and gaps along fascia and soffit joints, across roofline trims, gutter end caps and garage door frames.
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.
Every job is covered by a one-year guarantee, wherever you are in Argyll and Bute.

Landlord and commercial work in Shandon
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can be quoted together.
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will give you a quote.
DIY sealant or a professional job?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Leave it or put it right?
You do not need to replace a garage door because rain gets in round the frame. Sealing the frame generally stops it, if the frame itself is sound. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
What you pay reflects the work, not guesswork. That’s why we ask about the job first and send you a clear quote before we start.

What we’re called out for in Shandon
Sealant on fascias and trims weathers like any outdoor joint. It goes hard, cracks and pulls away over time.
Common reasons people contact us include:
- Damp patches inside below a leaking gutter
- Old gutter sealant that has let go
- Dripping gutter ends
- Drips from gutter joints and end caps
If you let a flat or house near Helensburgh Upper station, leaking gutter joints on a rental are best caught before they stain the walls.
What to look for in a quote
- How the surfaces are prepared before sealing
- How long the guarantee is
- How much experience the applicator has
- When the joint can take water or movement
Different surfaces, different methods
Garage door frames
The joint between frame and brickwork moves and weathers. We use a sealant made for outdoor joints.
Gutter joints
A dripping joint doesn’t always mean a failed gutter. Sealing the joint often stops it.

What gutter sealing looks like in Shandon
Shandon 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. That is hard on gutter, fascia and roofline joints, especially on the side facing the sea. Shandon is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for gutter, fascia and roofline joints to keep out.
In the older streets around Parish Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.
