Why Your Gutters Might Still Overflow After Cleaning
This is one of the most common — and most frustrating — complaints in gutter cleaning: a homeowner pays for a cleaning, gets an invoice that says the gutters were “cleared and functioning,” and the very next rain the water still overflows. The gutter wasn’t the problem. The downspout was.
Two Different Problems That Look Identical
A gutter trough — the horizontal channel that runs along your roofline — can be completely clear of leaves and pine straw and still overflow if the downspout it drains into is blocked. Downspouts clog in a different way than gutters do: compacted debris lower down in the vertical pipe, or a blockage in the underground drain line the downspout empties into at ground level. A visual check of the gutter trough from a ladder won’t catch either of those.
Why This Gets Missed So Often
Clearing a gutter trough is quick and visible. Checking whether water actually flows all the way through a downspout and out the other end takes an extra step — running water through it and watching what happens — that a fast, low-cost cleaning sometimes skips entirely. That extra step is the difference between a gutter that’s been touched and a gutter that’s actually working.
How We Handle It
We run water through every downspout on every job before we consider it finished — not as an upsell, as the standard. If a downspout or underground line is blocked separately from the gutter itself, that’s a distinct repair we’ll flag and quote honestly rather than folding it silently into a cleaning that won’t actually fix the overflow.

Frequently Asked Questions
Why would gutters overflow right after being cleaned?
Almost always because the downspout or its underground drain line is still blocked – a clear trough doesn’t mean water is actually draining away from the roofline.
How can I tell if it’s a downspout problem and not a gutter problem?
Run water into the gutter near a downspout – if it backs up or drains very slowly at the downspout opening, the blockage is downstream of the visible gutter.
Does a standard gutter cleaning include testing the downspouts?
It should, but not every company does it – this is the exact step to ask about before hiring anyone, since it’s the one most often skipped.
