Gutter sealing in Bonkle, done properly
Failed sealant round a garage door frame lets rain blow in. We cut out the old sealant and reseal the frame with an exterior sealant. Typical jobs include open joints in fascias and soffits and dripping gutter ends, on gutter joints, soffit joints and uPVC fascias.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. On newer homes, the movement joints and roofline trims are what need watching.
Each job carries a 12-month guarantee, large or small.

DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
Why deal with it now?
Water from a leaking joint hits the same spot every time. Over time that can stain brickwork, mark render and encourage damp so early sealing is worthwhile. Around Bonkle, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

What happens on the day
There’s no need to move everything out before we come, just the space around the work. Everything nearby is protected, and the work takes a few hours, depending on the number of joints and the access for a typical job. In smaller Scottish places, parking is generally less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- First we agree which joints need sealing.
- Each joint is cleaned and any old sealant removed.
- We make sure everything is dry.
- We apply exterior or gutter sealant and finish it neatly.
- The joints are checked once sealed.
How to prepare
- Move anything stored near the joints
- Mention any parking rules near the property
- For business premises, tell us about site rules or sign-in

Walls and rooflines in Bonkle
Harled (roughcast) walls are common in Scotland, and joints where harling meets other materials need a sealant that can grip and flex. Historic houses like Cambusnethan House (about 4.3 miles south-west) are a reminder that the area around Bonkle has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
Letting a property close to Hartwood station? Then a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside. If you live in an older home near Bonkle Parish Church, an extension built onto an older house moves differently, and the joint between them takes the strain.

When to call us in Bonkle
When a gutter sags, its joints open. Sealing will not hold if the gutter keeps dropping, so the gutter needs refixing first.
It’s worth asking for a quote if you see:
- Drips from gutter joints and end caps
- End caps that drip every time it rains
- Trim joints where the sealant has failed
- Old gutter sealant that has let go
If you look after a building such as Coltness High School, its movement joints, gutters and trims need looking after like any other building’s.

Different surfaces, different methods
uPVC fascias
Open fascia joints look untidy and can let water in. Sealing them closes the gap.
Roofline trims
We seal the trims, not the roof. Roofing problems need a roofer.
