Downpipe unblocking
If the gutter overflows in heavy rain, the downpipe is often the reason.
Clear, flush, test — every outlet
Many gutter cleans fail at the downpipe. Compacted leaves, a tennis ball, or thatch from a birds' nest forms a plug at the bend or the shoe, and the next downpour sends water over the fascia instead of to the drain. I check every outlet, not just the one you can see from the ground.
Method is simple and thorough: probe with a rod to locate the blockage, work it clear, then flush with water until I see clean flow at the ground. I finish by running water along the gutter so you can watch the level drop evenly — proof the line is open. If the shoe is buried or the drain is surcharged, I'll tell you plainly rather than pretend the gutter was the problem.
This work is included when you book a full gutter clean. As a standalone call-out, I still charge the quoted price with no travel fee added after — the same "price I quote is the price you pay" you'd expect from the $109 gutter tier. Most blocks happen on internal gutters and Taylor fascia systems where a hidden internal sump feeds a single downpipe; one block affects the whole run, so catching it early saves the ceiling below.
Downpipes are the narrow throat that decides whether your gutter works or floods the fascia. In Christchurch's older housing stock — especially New Brighton bungalows and 1970s brick-and-tile — a single blocked outlet can back up an entire run. I have cleared downpipes choked with oak leaves, pine needles, children's toys and the concrete-like slurry that forms when fine grit sits wet for months. The symptom is usually the same: water spills over the outer edge in rain you would not call heavy, and the ceiling below stays dry until the day it doesn't.
The test I use is simple and visible. After clearing, I pour a measured amount of water at the high end of the gutter and you watch the level fall evenly toward the outlet. No pooling, no hesitation at the bend. If the shoe discharges to a stormwater drain that is itself blocked, I will tell you — pushing water into a blocked drain just moves the problem underground. One reviewer noted I "highlighted an issue we had with our roof that needed a fix" rather than adding a line to the invoice.
For landlords and property managers in Canterbury, I coordinate gutter and downpipe checks between tenancies so overflow doesn't become a tenant complaint. For homeowners, I note the time of year and the trees around your street — a Titahi Bay macrocarpa sheds differently from a New Brighton silver birch — and suggest a sensible interval. Every job is still one person, one visit, one price quoted before I start.
