Gutter sealing for homes and businesses in Cardross
Gutter and fascia replacement isn’t our trade, and nor is roofing. What sealant does is close joints and it can’t mend broken brackets, split sections or blocked downpipes. We work on roofline trims, soffit joints and garage door frames, and people most often call us about damp on an inside wall under a dripping gutter and wet patches on the wall under a gutter joint.
External sealant needs dry surfaces, so outdoor work around Cardross is planned around the weather. Let us know about access to every wall and roofline.
Whatever the size of the job, it’s backed by our 12-month guarantee in Cardross and across West Dunbartonshire.

How the visit works
The work is kept neat and contained to the area we are working on, so you can carry on as normal. The job usually takes anything from an hour or two to a few hours, and we tell you how long to leave it before we go. Outside jobs in Cardross 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. Work indoors is not affected.
- 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 area is dried so the sealant can bond.
- 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.
Before we arrive
- Clear items away from the joints we’re working on
- Mention any tricky access
- Let us know about earlier repairs to the joints

What gutter sealing looks like in Cardross
Cardross is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on gutter, fascia and roofline joints, especially on the side facing the sea. The west of Scotland is wetter than the east, which means gutter, fascia and roofline joints has to cope with a lot of rain.
Homes close to Parish Church include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant. Rented homes near Cardross station change hands often, and a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.

Why it’s worth doing now in Cardross
New gutters cost far more than a few resealed 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.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

Should I try it myself first?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
