Gutter sealing in Southerness, done properly
We don’t replace gutters, fascias or roofs. What sealant does is close joints; it won’t fix a broken bracket, a cracked section or a blocked downpipe. Common call-outs are for quick sealant fixes on gutters that didn’t last and damp on an inside wall under a dripping gutter, on roofline trims, garage door frames and soffit joints.
In and around a place like Southerness, many buildings face open ground and take the full weather. Outside joints on exposed walls work hard.
Your job is guaranteed for a year, as with all our work.

DIY sealant or a professional job?
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.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Southerness buildings and the weather
Southerness is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on gutter, fascia and roofline joints, which can dry out and crack sooner where a building faces the weather. Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex.
Whether the job is in Southerness itself or nearby, the right material for each joint matters as much as a neat finish. Around Southerness, as everywhere, gutter sealing is only as good as the preparation behind it.

Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Deal with a drip before winter
- Rest ladders on the wall, not the gutter
- Don’t leave a sagging gutter
- Look along the fascias for open joints
While checking gutters, glance at the fascia joints too. Splits are easier to seal early.
If an end cap is dripping, deal with it before winter. Water down the wall all winter can cause damp inside.
What happens on the day
A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and tidy away. It usually takes a few hours, depending on the number of joints and the access. Somewhere like Southerness may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- We find where the water is coming from and check the gutter is sound.
- We remove the old sealant and clean the joint.
- We dry the joint so the new sealant can bond.
- A gutter sealant is applied to the joint.
- The gutter is checked and debris around the joints cleared.
Preparing for the visit
- Let us know about parking restrictions
- On commercial sites, let us know about site rules
- Mention if the joints have been sealed before

Surface by surface
Gutter joints
When a joint drips, the gutter is often still sound. Sealing the joint often stops it.
Roofline trims
We seal the trims, not the roof. A roofer deals with the roof itself.
