What gutter cleaning includes.
Gutter cleaning removes the leaves, sticks and packed debris that stop gutters draining, then proves they drain: every run and every downspout is flushed with water. A gutter that looks empty from the lawn can still be blocked at the downspout.
For homes and businesses across Suffolk County.
All debris removed
By hand, the full length of every gutter.
Gutters and downspouts flushed
Water through every run.
Downspouts checked for clogs
Surfaces cleaned
The gutters themselves, not just their contents.
Why clogged gutters cost more than a cleaning.
A blocked gutter doesn’t stop the water — it just sends it somewhere else. It spills over the edge, streaks down the siding, soaks the beds below and pools against the foundation. That’s how water damage, foundation problems and mold start.
The standing water left in a clogged gutter is a breeding ground for mosquitoes too.
Overflowing when it rains
Water sheeting over the edge instead of down the spout.
Visible debris
Leaves and sticks you can see from the ground.
Water stains on the siding below
Streaks under the gutter line.
After the leaves drop, or a winter storm
Fall leaves and storm debris fill them fastest.
How we clean gutters.
Set up safely
Trained techs working to company safety guidelines, with the right ladders and high-reach equipment for second- and third-story rooflines.
Clear every gutter by hand
Leaves, sticks and packed debris removed from the full run of gutter — not just the corners you can see from the lawn.
Flush gutters and downspouts
Water through every run and down every downspout, so you know it drains, not just that it looks empty.
Check and clean up
Downspouts checked for clogs and the gutter surfaces cleaned before we leave.
Water already in the basement?
That’s our other half.
While we’re up there.
Streaked roofs and dirty siding usually show up alongside clogged gutters. Both are soft-washed, never pressure-washed.
What it costs.
There’s no flat price: a single-story ranch and a three-story house with a wraparound porch aren’t the same job.
Free estimate. The price you’re quoted is the price you pay.
Length of gutter
Measured in feet of gutter, plus the number of downspouts to flush and check for clogs.
Height and access
Single-story gutters are quicker than second- and third-story rooflines that need high-reach equipment and more setup.
How packed they are
One fall's leaves clear quickly; years of compacted debris take longer to dig out and flush.

Frequently asked questions
Straight answers on cost, timing and what's included.
How much does gutter cleaning cost?
It depends on how many feet of gutter there are, how high the house is, and how packed they are. The estimate is free, and the price you're quoted is the price — no hidden fees.
How often should gutters be cleaned?
Whenever they fill. On Long Island that usually means fall, once the leaves are down, and again in spring to clear what winter storms left behind. Houses under mature trees fill fastest.
What's included?
Every gutter cleared by hand, gutters and downspouts flushed, downspouts checked for clogs, and the gutter surfaces cleaned.
What happens if I don't clean my gutters?
They overflow. Water spills down the siding and pools at the foundation — staining the house and landscaping, and leading to water damage, foundation problems and mold. Standing water in a clogged gutter also breeds mosquitoes.
Can I clean my gutters myself?
On a one-story house with a sturdy ladder, maybe. Second- and third-story rooflines are where ladder work gets dangerous — which is why most people hand it off.
Do you clean gutters for businesses?
Yes — homes and commercial properties across Suffolk County.
Water's already come into the basement — can you help with that?
Yes. That's K.O.S.'s restoration side: 24/7 water damage restoration and mold remediation. Call and it's handled by the same company.
