Everything gutters, nothing else
One trade. Six services. Done right the first time.
We don’t paint, side, or roof. Gutters are all we do — installation, cleaning, repair, guards, copper work, ice-dam fixes. When you specialize in one thing, you get fast, and you stay honest.
Seamless Gutters Long Island — Nassau & Suffolk County
LI Gutter Service provides seamless gutter installation across all of Long Island, covering Nassau County and Suffolk County from a single East Meadow base. Our Senox roll-forming machine arrives on your driveway and forms continuous aluminum gutters to the exact length of your fascia — no field seams, no future leak points. We offer 5-inch and 6-inch K-style seamless gutters in aluminum, and half-round copper for historic and Tudor-style homes.
Gutter cleaning across Nassau and Suffolk is handled by our dedicated cleaning crew, who hand-bag debris, snake downspouts, and run a full flow test before leaving every job. Gutter guards — micromesh, reverse-curve, and screen — are installed on new or existing gutters throughout the island. Nassau County towns we serve include Great Neck, Smithtown, Hauppauge, Massapequa, Hicksville, Garden City, and Westbury. Suffolk County coverage extends to Huntington, Commack, Bay Shore, Babylon, Islip, Patchogue, Port Jefferson, and Stony Brook.

Seamless Gutter Installation Nassau County & Suffolk County
Nassau County
We install seamless gutters across Nassau County, including Hempstead, Garden City, Massapequa, Hicksville, Westbury, Levittown, East Meadow, Great Neck, Oyster Bay, and Valley Stream. Our East Meadow shop puts most Nassau County jobs within a 20-minute drive. Same-week quotes available throughout the county.
Suffolk County
Suffolk County coverage runs from Smithtown and Hauppauge in the west through Huntington, Commack, Babylon, Bay Shore, Islip, Patchogue, and Port Jefferson to the east. Smithtown is one of our most active Suffolk markets — gutter cleaning, seamless installation, and replacement requests come in year-round from the Smithtown, Kings Park, and St. James area.
6 Inch Seamless Gutters Long Island
Six-inch gutters are the right call for most Long Island homes. Our island sees some of the heaviest rainfall on the East Coast, and nor’easters can drop two inches of rain in under an hour. A standard 5-inch gutter handles around 1.2 inches of rain per hour per 100 sq ft of roof — a 6-inch handles roughly 40% more. For colonials with steep pitches, large roof planes, or significant tree canopy, 6-inch seamless aluminum prevents the overflow and fascia rot that undersized gutters cause. We form 6-inch K-style runs on-site in the same Senox machine as our 5-inch, so there’s no upcharge for production — just a small material difference. Ask us whether 6-inch is right for your home at your free estimate.
6 Inch Seamless Gutters — Smithtown, NY
Smithtown’s wooded neighborhoods — Kings Park, Nesconset, Hauppauge, and St. James — generate one of the heaviest leaf loads in all of Suffolk County. The mature oak, maple, and tulip-tree canopy means gutters fill up fast and need to move water fast. Six-inch seamless gutters handle roughly 40% more water volume than standard 5-inch gutters, which matters when a nor’easter drops two inches of rain in an hour on a steep-pitched colonial roof. Many Smithtown homes built in the 1960s through 1980s still have original 4-inch aluminum gutters — the kind that overflow in a moderate rainstorm and have been sagging and leaking for years. Replacing them with 6-inch seamless aluminum is one of the highest-ROI gutter upgrades we do.
We form 6-inch K-style seamless aluminum gutters on your Smithtown driveway, cut to the exact length of your fascia, with no field seams. Hidden hangers every 24 inches, pitched to grade, flow-tested before we leave. Most Smithtown gutter replacements are completed in a single day. We’re familiar with the heavy fall debris load in Kings Park and the ice-dam history on Smithtown’s north-facing roof slopes. Free estimates, most jobs scheduled within 7 days.
Why do Smithtown homes need 6-inch gutters more than other LI towns?+
Smithtown's tree canopy is unusually dense — mature oaks and maples in neighborhoods like Kings Park, Nesconset, and Hauppauge drop more leaf debris per square foot than most Nassau County streets. That debris combined with steep-pitch colonials common in the area means standard 5-inch gutters get blocked and overflow more often. Six-inch gutters slow down the cycle, handle higher water volume, and give guards more surface area to work with.
How much does 6-inch seamless gutter installation cost in Smithtown NY?+
Six-inch seamless aluminum gutters in Smithtown typically run $9–$14 per linear foot installed, depending on fascia condition, number of downspouts, and whether any corners or miters need special treatment. A typical Smithtown colonial with 180 linear feet lands in the $1,800–$2,600 range. We itemize every line item in writing at your free on-site estimate.
Can you replace my old 4-inch aluminum gutters with 6-inch seamless in Smithtown?+
Yes — we do this regularly in Smithtown, Kings Park, and Hauppauge. We tear off the old gutters, inspect the fascia for rot or damage (and repair it if needed), install new apron flashing, and form and hang new 6-inch seamless aluminum runs on the same visit. Most full replacements finish in one day.
Do you clean gutters in Smithtown NY?+
Yes — gutter cleaning in Smithtown is one of our most active services year-round. We hand-bag debris, snake downspouts, and run a flow test on every cleaning. We also offer spring and fall cleaning packages for Smithtown homeowners on annual maintenance. Cleanings are usually scheduled within 3–5 business days.
Gutter Cleaning Hauppauge NY
Hauppauge is one of our most active gutter cleaning markets in Suffolk County. Between the Hauppauge Industrial Park neighborhoods and the residential streets off Veterans Memorial Highway, we run cleaning crews through Hauppauge spring and fall every year. Hauppauge’s mix of mature trees and mid-century ranch and colonial homes means gutters fill up quickly — blocked downspouts and overflowing front fascia are the two most common calls we get from the area.
Every Hauppauge gutter cleaning includes hand-bagging all debris, snaking downspouts, flushing with water, and a before/after photo set. We also inspect fascia condition and gutter pitch while we’re on the ladder — if we spot a sagging run or a leaking miter, we’ll flag it and give you a repair price on the spot. Most Hauppauge cleanings are scheduled within 3–5 business days. Call (516) 874-8200 or request a quote online.

What to expect

Measure & walk the roof
We measure linear feet, count inside/outside corners, check fascia condition, confirm pitch, and map downspout runs to grade.
2
Written quote, same visit
Line-item pricing: gutters, downspouts, guards, labor, disposal. Everything on paper. No verbal estimates, no 'let me call the office.'
3
Schedule within 7 days
Once you approve the quote, we're usually on-site within a week. Weather-dependent. We call the night before to confirm.
4
Form, hang, test, cleanup
Gutter machine on the driveway, continuous runs in under 2 hours for a typical colonial. Hidden hangers every 24". Flow test before we leave. Magnet sweep for nails.

Here’s what a few Nassau and Suffolk homeowners said recently.
“Called on a Tuesday for gutter cleaning, they were out Friday. Fully insured, sent before/after photos. Exactly what you want from a local contractor.”
“Got three quotes for gutter guards. LI Gutter was the only one that explained micromesh vs reverse-curve vs screens without trying to upsell me to LeafFilter at 3x the price.”
“Ice dam tore down our back gutter in January. Kyle showed up two days later, replaced the run, fixed the pitch, installed heat cable. Problem hasn't come back.”
“Copper half-round on our Tudor. The work is beautiful — patina is coming in exactly like Tony said it would. Worth every dollar.”
“These guys replaced 220 linear feet in a single day. Clean, polite, magnet swept for nails. Even fixed a rotted fascia board I didn't know about for a fair add-on price.”

Common questions
The stuff homeowners ask us on every call.
Still have questions? Call (516) 529-6634— Maria picks up between 7am and 5pm.
(516) 529-6634Most single-family homes — colonials, capes, ranches, splits — take one full day. A 2,000 sq ft colonial with 160 linear feet and 6 downspouts is about 6-7 hours including tear-off, forming, hanging, and cleanup. Larger homes (over 240 lf) or steep gable work can stretch to a day and a half.
Seamless gutters are formed continuously from a single coil of aluminum right on your driveway, so the only seams are at corners and downspout outlets. Sectional gutters (the kind sold at big box stores) have a seam every 10 feet — and every seam is a future leak. On Long Island's heavy rain and freeze-thaw cycles, sectional gutters typically fail at seams within 5-7 years. Seamless aluminum lasts 20+ years.
Honest answer: depends on your trees and roof. Micromesh stainless (LeafFilter, Gutter Helmet's mesh line, LeafGuard Brothers) is the gold standard for homes near oaks, maples, and pines — it blocks pine needles and shingle grit that clog everything else. Reverse-curve (LeafFilter's curved system, Gutter Helmet's classic) is great if you already have 6" gutters. Plain screens and foam are cheaper but clog faster. We'll walk you through tradeoffs at your free estimate.
Ranges we commonly install: aluminum 5" seamless runs $7-$12 per linear foot installed. 6" runs $9-$14. Copper half-round is $28-$45 per linear foot. Typical Long Island colonial (160-200 lf with 5-6 downspouts) lands in the $1,800-$3,200 range for aluminum, depending on fascia repairs and guards. We itemize everything — see our /pricing page for the full breakdown.
Both. Kyle runs our cleaning crew — spring and fall cleanings, emergency clogs, downspout snaking, and flow tests. Single-story cleanings start at $150; two-story $225. Add guards if you're cleaning twice a year and tired of it. See /services/gutter-cleaning for details.
