Gutter sealing in Thornton, done properly
Sealant only bonds to a clean, dry joint. So the old sealant and grime come out first and the joint is dried before the new sealant goes in. We work on gutter joints, uPVC fascias and gutter end caps, and people most often call us about stop ends leaking at the end of a run and leaking gutter joints and stop ends.
External sealant needs dry surfaces, so outdoor work around Thornton is planned around the weather, and longer journeys are planned in advance. Let us know about access to every wall and roofline.
Each job carries a 12-month guarantee, large or small.

Why deal with it now?
Sealant won’t clear a blocked downpipe. We look at what’s really happening and tell you if something else is needed. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference.
Why Thornton customers choose us
- A 12-month guarantee on all work
- Approved under the ARBOMaster scheme
- Anti-fungal silicone where joints get wet
- We never seal over old sealant

Surface by surface
Soffit joints
Open soffit joints let draughts in. We close them with a suitable sealant.
Gutter end caps
A leaking end cap sends water straight down the wall. It’s a quick reseal.
Can I do it myself?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Outside joints around Thornton
Thornton is within about 3 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on gutter, fascia and roofline joints, especially on the side facing the sea. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
If you live in an older home near Old Parish Church, an extension built onto an older house moves differently, and the joint between them takes the strain.
