Gutter sealing in Luss
Open fascia and soffit joints spoil the roofline and can let weather in. They’re sealed in a matching colour where one is available. We’re often asked to deal with rain getting in around a garage door and internal damp traced to a gutter joint, on gutter end caps, uPVC fascias and roofline trims.
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, large or small.

Are you an approved applicator?

DIY versus a professional finish
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
What the job involves on each surface
Soffit joints
We choose a sealant colour that suits the soffit, where one is available.
Garage door frames
Failed sealant around a garage door frame lets water in. We cut it out and reseal.
How it works
Once we are on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours, depending on the number of joints and the access. Outside jobs in Luss need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- First, we find the drip and check the gutter is not cracked or sagging.
- We clean out the joint and take out the old sealant.
- The joint is dried, because sealant will not bond to a wet surface.
- We seal the joint with a sealant made for gutters and outdoor use.
- We check the run and clear any debris we find while we are there.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about any previous sealing or DIY attempts

What else we do in Luss
Luss buildings and the weather
The west of Scotland is wetter than the east, which means gutter, fascia and roofline joints has to cope with a lot of rain. Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex.
In and around Luss, as anywhere, good gutter sealing starts with a clean, dry, properly prepared joint. If you live in an older home near Luss Parish Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Why act early in Luss
Replacing guttering is a much bigger job than sealing joints. If the gutter is sound and the drip is a joint, resealing is the sensible fix. If it’s broken or sagging, a gutter installer needs to look. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.
