- Water running down the wall below the gutter
Surface by surface
uPVC fascias
Joints between fascia boards can open over time. They’re sealed tidily with a matching sealant where possible.
Gutter joints
Gutter joints move and sit in water. A dedicated gutter sealant suits them.
Gutter sealing in Cumbernauld, done properly
Gaps along uPVC fascias and soffits look untidy and can let in water and draughts. We seal them in a colour to suit where possible. We work on gutter joints, gutter end caps and soffit joints, and the jobs we see most are water running down the wall below the gutter and internal damp traced to a gutter joint.
Harled walls are common in Scottish towns like Cumbernauld, and the joints where harling meets windows, doors and pipes need a sealant that grips and flexes. Rooflines take their share of the weather as well.
There’s a 12-month guarantee on every job, whatever its size.

Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Work for landlords, hotels and businesses
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
Signs you need gutter sealing in Cumbernauld
Stop ends take pressure from water running along the gutter. If the seal fails, water escapes at the end and runs down the wall.
Any of these means the joints need attention:
- Water running down the wall below the gutter
- Fascia boards with gaps between them
- Earlier gutter repairs that have peeled off
- Water dripping where gutter sections meet
Rented homes near Cumbernauld station change hands often, and leaking gutter joints on a rental are best caught before they stain the walls.

Why deal with it now?
Sealing over a dirty, wet joint is a quick fix that rarely lasts, but it soon lets go. Proper preparation is the difference. Scottish weather finds any gap, and in a town like Cumbernauld, failed outside joints soon let damp into walls. Indoors, failed sealant lets water into floors and ceilings.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
Why book with us
- Quality sealants from Arbo and Everbuild
- Anti-fungal silicone where joints get wet
- Over 20 years’ experience
- Fully insured

What does gutter sealing cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.
Can new sealant go over the old?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
Can I add another job to the visit?
Yes, we can. More than one area can be quoted together.
Do the sealants smell?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.

What gutter sealing looks like in Cumbernauld
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. Plenty of Scottish homes have harled walls, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface.
If you live in an older home near St Mungo's Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep. Schools such as Our Lady's High are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
