How we handle gutter sealing in Bonaly
Water dripping from a gutter joint can stain walls and soak the ground below. Resealing the joint is often all it needs, as long as the gutter is sound. If you have drips from gutter joints and end caps and wet patches on the wall under a gutter joint, we can help, on gutter joints, gutter end caps and uPVC fascias alike.
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.
A one-year guarantee comes as standard.

What else we do in Bonaly
DIY versus a professional finish
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
If you’ve already had a go yourself, that is fine. We cut it out and start again.
What gutter sealing looks like in Bonaly
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. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
If you look after a building such as Army School of Bagpipe Music and Highland Drumming, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. In the older streets around Colinton Parish Church, an extension built onto an older house moves differently, and the joint between them takes the strain.

Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Watch for drips in a downpour
- Make sure downpipes are not blocked
- Watch the wall under the gutters for staining
- Deal with a drip before winter
Leave the new sealant to cure as we advise and avoid disturbing it.
If an end cap is dripping, deal with it before winter. Water down the wall all winter can cause damp inside.
Why it’s worth doing now in Bonaly
A bead squeezed onto a wet joint might hold for a while but it tends to peel off. Cleaning out and drying the joint first is what makes it last. 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.
Doing several joints on one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We’ll send you a clear quote for the lot.

How it works
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes an hour or two for a few joints, longer for a full run. For a place like Bonaly, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- 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’re there.
Preparing for the visit
- Keep children and pets away from the work area
- Try not to wet indoor joints just before the visit
- Tell us about access, such as stairs, a lift or high-level joints

Related advice
Common problems we fix in Bonaly
When a gutter sags, its joints open. Resealing a sagging joint will not last, so the gutter needs refixing first.
Any of these means the joints need attention:
- Gaps along fascia and soffit joints
- Dripping gutter ends
- Water dripping where gutter sections meet
- Cracked sealant along roofline trims
Rented homes near Kingsknowe station change hands often, and leaking gutter joints on a rental are best caught before they stain the walls.
