Seamless gutters are the only type of gutter we install on primary runs. The machine on our truck rolls continuous aluminum to the exact length of your fascia, which means seams — the #1 cause of gutter failure — exist only at corners and downspout outlets, instead of every 10 feet like big-box sectional gutters.

On Long Island's rain patterns (100-year storms every four years, it feels like) and our freeze-thaw cycles, sectional gutters start leaking at the seams by year 5-7. Seamless aluminum, hung correctly with hidden hangers every 24 inches, lasts 20-30 years. Copper lasts 60+.

We form on your driveway. You watch it happen. You get a piece of gutter as long as the side of your house, in one continuous piece. No compromise, no seams, no future leaks.

Seamless Gutter Installation on Long Island

What’s included

Here’s exactly what we do on every seamless gutter job.

Tear-off of existing gutters

Including magnetic nail sweep of landscaping and a clean jobsite at the end.

Fascia inspection & minor repairs

We check every board before hanging. Rotted sections get replaced (time and materials; itemized upfront).

Apron flashing & drip edge

New flashing tucks under the shingles, over the gutter lip — keeps wind-driven rain from getting behind.

Continuous seamless aluminum

5" or 6" K-style, formed on-site, heavy-gauge .032 coil — not the .027 big-box sectional stock.

Hidden hangers every 24 inches

No spike-and-ferrule junk. Screwed into solid wood, not nailed into old nail holes.

3x4 downspouts (or 4x5 on big runs)

3x4 moves ~50% more water than the standard 2x3. On big roof sheds, that's the difference between overflow and no overflow.

Splash blocks or French drain hookups

Water needs to leave the house. Splash blocks included on grade; we can tie into existing French drains.

Flow test before we pack up

Tony walks every run with a hose while Kyle watches the downspouts. We don't leave until water flows.

Before/after photos in your email

Texted to you the same day. Install photos, nameplate on the downspout, and the finished look.

Our process

Four steps, written on the quote.

Seamless Gutter Installation on Long Island process
1

Measure + walk the roof

We count linear feet, inside/outside corners, and confirm pitch. We look at your fascia, your kickouts, and your downspout routes. 15-20 minute visit.

2

Written quote, same day

Line-item pricing for tear-off, gutters, downspouts, flashing, fascia repair, guards, disposal — everything on paper, no verbal pricing.

3

Schedule within 7 days

Most installs happen within a week of quote approval. Weather-dependent. We call the night before to confirm start time.

4

Form, hang, flash, test, cleanup

Gutter machine on your driveway at 8am. Most single-family Long Island homes finish between 2-4pm. Full cleanup + magnet sweep before we pull out.

Materials & options

Here’s the honest rundown of your options.

Aluminum (most popular)

Aluminum (most popular)

Heavy-gauge .032 aluminum coil. 27 color options. 20-30 year life on Long Island. $7-$12/lf installed.

Steel (commercial / coastal)

Steel (commercial / coastal)

Heavier than aluminum; better for commercial buildings or homes within 1,000 feet of salt water. $9-$14/lf.

Copper half-round

Copper half-round

Soldered seams, true half-round profile. Tudor, Colonial, historic homes. $28-$45/lf. 60-year life.

K-style vs half-round

K-style vs half-round

K-style holds ~40% more water per linear foot than half-round. Half-round looks period-correct on older homes and self-cleans better. We carry both.

5-inch vs 6-inch

5-inch vs 6-inch

5-inch is standard residential. 6-inch is recommended for steep/large roofs, long fascia runs, or homes under heavy tree cover. Same install price difference is small.

Gutter guard compatible

Gutter guard compatible

All our seamless gutters are guard-ready. We can install guards at time of new install or retrofit later.

Got three quotes for gutter guards. LI Gutter was the only one that didn't try to upsell me to LeafFilter at 3x the price.

Common questions

Before you schedule, here’s what homeowners ask.

Still wondering about something? Call (516) 529-6634and we’ll walk you through it.

Sectional gutters come in 10-foot factory sections you screw together. Every seam is sealed with caulk or silicone — and every seam is a future leak. Seamless gutters are rolled continuously from a coil on our truck, so your 45-foot run is one piece of aluminum with zero seams in the middle.
.032 gauge. That's 25% thicker than the .027 aluminum most competitors use (and most big-box sectional gutter is even thinner). .032 holds hanger screws better, resists dents, and handles ladders leaning on it without folding.
Never. Spike-and-ferrule is the old 1970s method — a nail driven through the front of the gutter and out the back. They pull out in 5-10 years and leave holes. We use hidden hangers screwed into the fascia every 24 inches. They never pull out and they don't show from the ground.
Usually yes. We carry 27 stock colors in .032 coil. If you have an unusual color, we'll email you a color chart and pick the closest match, or order a custom coil (adds 2-3 weeks).
A 200 lf aluminum 5-inch job with 6 downspouts, tear-off, new flashing, and splash blocks typically lands between $1,800 and $2,800 — depending on fascia condition, pitch, color, and whether you add guards. You'll get a line-item written quote before we start.
Most Long Island colonials, capes, ranches, and splits take one day — usually 6-8 hours including tear-off, forming, hanging, flashing, and cleanup. Bigger homes (300+ lf) can go into a day-and-a-half.
Yes, routinely. We inspect every board before we hang. If we find rot during tear-off, we stop and show you, then wrap the repair into the job at time-and-materials pricing (we itemize it on the invoice). Typical fascia board replacement runs $60-$120 per 16 feet installed.
