About our gutter sealing in Garthamlock
Across Garthamlock, we reseal gutter joints, end caps and roofline trims. Single-storey and low gutters are simple to reach and if it’s higher up, let us know and we will confirm what access is needed. We work on gutter end caps, roofline trims and gutter joints, and common reasons people get in touch are fascia boards with gaps between them and dripping gutter ends.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. Newer houses need their movement joints and roofline trims kept sound.
All of our work is guaranteed for twelve months.

Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
Walls and rooflines in Garthamlock
Garthamlock 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. Harled (roughcast) walls are common in Scotland, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface.
Homes close to Saint Benedict's Church include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant. For site and facilities teams at buildings such as St Andrew's Secondary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. If you let a flat or house near Stepps station, a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.

Why deal with it now?
Sealant won’t clear a blocked downpipe. We check the cause first and tell you if something else is needed. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Combining jobs into one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.
