Gutter, fascia & soffit sealing in St Leonards, South Lanarkshire
Professional gutter sealing in and around St Leonards, with old sealant always removed completely and a 12-month guarantee.
- Leaking gutter joints and stop ends
- Garage door frames letting rain in
- End caps that drip every time it rains
Keeping the joints in good condition
So the new joints stay in good condition:
- Deal with a drip before winter
- Keep ladders off the guttering
- Look at the gutters while it’s raining
- Clean out the gutters once or twice a year
Look at fascia and trim joints when you are checking the gutters. A small split is quicker to put right.
Early sealing limits how much water hits the wall. We’ll let you know if the gutter needs more than sealant.
Gutter sealing in St Leonards, done properly
Our work covers gutter joints and end caps as well as fascias and soffits plus roofline trims and garage door frames. It’s joint work, not replacing the gutter. If you are dealing with rain getting in around a garage door and trim joints where the sealant has failed, we can help, whatever the surface.
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.
Your job is guaranteed for a year, as with all our work.

DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.

Advice
Why it’s worth doing now in St Leonards
Leaving a leaking end cap can send water down the wall all winter. Resealing it is a quick job before the damage spreads. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
