Gutter Shutter is a dealer-installed, all-in-one gutter system: a 6-inch seamless aluminum gutter made from 0.032-inch aluminum, topped by a separate rolled hood that uses surface tension to pull rainwater in while leaves slide off. It is made by Gutter Shutter LLC of Seymour, Connecticut, sold only through independent authorized dealers, and backed by a lifetime no-clog warranty and a 20-year paint warranty. The company publishes no prices, so every number you see is a dealer quote or a third-party estimate.
That makes Gutter Shutter a different purchase from a guard you clip onto old gutters. You are buying new gutters, downspouts and a hood in one job, and the hood is a reverse-curve design, which brings the strengths and the heavy-rain limits of that category. This review covers what the system is, how it works, what the warranty language actually says, what the public record shows on cost and the Better Business Bureau, and how it compares with LeafFilter, LeafGuard and Gutter Helmet.

What is Gutter Shutter?
Gutter Shutter is a brand of integrated gutter and gutter guard system, not a standalone guard. Gutter Shutter LLC manufactures the components and sells them through a network of authorized, independent dealers, who measure, quote and install. The company says it was founded in 2003, and its press releases list Seymour, Connecticut as the dateline for the company.
Gutter Shutter describes itself as part of Contractor Nation, a network founded by Larry Janesky that also includes Basement Systems, Foundation Supportworks and Dr. Energy Saver. The Better Business Bureau profile for the Seymour headquarters lists Larry M. Janesky as CEO. A Gutter Shutter LLC patent application published on May 7, 2026 (US 2026/0125904 A1, a “valley flow controller”) names Janesky as an inventor, and a 2021 design patent for a downspout (US D931,425) is assigned to Gutter Shutter LLC.
Because dealers are separate companies, your experience depends heavily on the local installer. Many dealers trade under names like “Gutter Shutter of Greater Atlanta,” while others are roofing or basement contractors that add the product to their line. Our guide to the main types of gutter guards explains where this kind of system sits among the five guard categories.
Is Gutter Shutter still in business?
Yes. Gutter Shutter LLC announced new authorized dealers in Tennessee, North Carolina and Georgia on March 13, 2026, and in northern Indiana on June 5, 2026, according to press releases on its website. The question often comes from search listings for individual local companies: for example, Yelp marks a Cincinnati listing named The Gutter Shutter Co as closed. Since each dealer is an independent business, check the status of the specific company quoting your job.
How does Gutter Shutter work?
Gutter Shutter works on surface tension. Rain running off the roof follows the rounded nose of the hood and curls back into the gutter, while leaves and twigs are too stiff to follow the curve and fall to the ground. Gutter Shutter compares it to water clinging to the side of a glass as you pour, and says there are no screens, inserts or filters to clog.
The manufacturer lists several parts that make up the system. Each part has a job, and knowing them helps you read a dealer’s quote line by line.
| Component | What Gutter Shutter says it does | Source |
|---|---|---|
| Rolled hood | Covers the gutter; water wraps around the nose by surface tension, debris falls off | guttershutter.com, Q&A and Compare Gutter Guards pages |
| Flow reducers and perforated hood | Slow roof runoff and control the volume of water entering the gutter | guttershutter.com, Benefits of Our System page |
| High back | Extends up behind the gutter to cover the fascia and keep water from getting behind it | guttershutter.com, Benefits of Our System page |
| GutterStud bracket | Polymer (mostly virgin nylon) bracket supporting back, front and hood, every 24 inches | guttershutter.com, Q&A and Benefits pages |
| End caps | One-piece end caps that encase both gutter and hood | guttershutter.com, Benefits of Our System page |
| Wide-mouth outlet and 3 x 4 inch downspouts | Move water out of the gutter faster than a standard outlet and 2 x 3 inch downspout | guttershutter.com, Compare Gutter Guards page |
| Pine needle design | Listed as available; details are not published | guttershutter.com, Compare Gutter Guards page |
Is Gutter Shutter a one-piece or two-piece system?
Gutter Shutter’s own pages describe it both ways. Its comparison chart lists “one-piece design” as a feature, but its Q&A page says the system uses a two-piece design in which a separate hood is secured to the bracket and trough, so a damaged hood can be replaced without replacing the seamless gutter. In practice, the hood and gutter are separate parts installed together as one integrated system, which differs from LeafGuard’s single formed piece. For how that one-piece design holds up, see our LeafGuard review.
Does Gutter Shutter go under the shingles?
No, according to the manufacturer. Gutter Shutter says the system installs under the drip edge, not under the shingles, and fastens directly into the fascia board. That is why the company says it does not interfere with a roof replacement and should not affect a shingle warranty. Gutter Shutter’s comparison page warns that guards nailed under the shingles may put a roof warranty at risk, so check your shingle maker’s terms if a competing quote uses that method.
Gutter Shutter materials, gauge and capacity
Gutter Shutter builds its gutters and hoods from 0.032-inch aluminum with a factory-baked enamel finish, uses a 6-inch gutter profile and pairs it with 3 x 4 inch downspouts. Those choices put it at the heavy end of residential aluminum gutter systems. The manufacturer lists 12 colors on its color page, including White, Almond, Musket Brown, Black and Forest Green.
Three of the manufacturer’s capacity claims can be checked with simple arithmetic. The table shows the claim, the math, and what it means.
| Claim | Roofing Brief arithmetic | What it means for you | Source of claim |
|---|---|---|---|
| 0.032-inch aluminum, thicker than typical residential gutters | Residential aluminum gutter coil is commonly sold in 0.027 and 0.032 inch. 0.032 / 0.027 = 1.185, about 19% thicker | Thicker coil is generally stiffer and less prone to dents and sag than 0.027 coil | guttershutter.com |
| 3 x 4 inch downspouts are “double the size” of 2 x 3 inch | 3 x 4 = 12 sq in; 2 x 3 = 6 sq in. Nominal cross-section is 2.0 times larger | Checks out on nominal dimensions; fewer downspout clogs and faster drainage | guttershutter.com |
| 6-inch gutter carries 20% more water than a standard 5-inch | Not independently verifiable from published data; capacity depends on the profile’s cross-section, not width alone | Treat as a manufacturer claim; ask the dealer for the profile drawing | guttershutter.com |
The downspout claim holds on nominal dimensions. The gutter capacity claim is plausible for a larger K-style profile, but Gutter Shutter does not publish the cross-sectional area that would let you confirm the 20% figure.
What does the Gutter Shutter warranty cover?
Gutter Shutter advertises three protections: a lifetime no-clog warranty, a 20-year paint warranty covering the factory-baked enamel against chipping and flaking, and a no-sag, no-pull guarantee that the company describes as lasting “for the lifetime of the structure.” The full warranty certificate is not posted online. The warranty page tells buyers to contact their local dealer to learn more.
The website does not say whether the warranties transfer to a new owner, who performs service if the original dealer closes, or what exclusions apply. Those three points are where gutter warranties differ most. For comparison, LeafGuard’s posted certificate states that performance claims for clogging are “the sole responsibility of the installing dealer,” and it excludes gutters installed within half a mile of the seacoast. Gutter Shutter’s terms may be different, which is why the certificate matters.
Before you sign, get written answers to these questions. They take five minutes and settle most warranty disputes before they start.
- Ask for the full warranty certificate, not the brochure summary, and keep a copy with your contract.
- Ask whether the lifetime no-clog warranty is backed by Gutter Shutter LLC, by the dealer, or by both, and who you call if the dealer goes out of business.
- Ask whether each warranty transfers to the next owner, and whether coverage changes after a sale.
- Ask what “clog” means under the warranty: debris inside the trough, debris resting on the hood, or water overshooting the nose.
- Ask about exclusions for ice, storms, tree damage, coastal salt exposure and roof work by other contractors.
- Ask whether you must register the warranty and by what deadline.
How much does Gutter Shutter cost?
Gutter Shutter does not publish prices. Every product page ends with a request for a free in-home estimate, and the Q&A page refers to a “Best Value Guarantee” without stating terms. The only cost figures in the public record are dealer marketing claims, a dated owner estimate and national surveys of comparable professionally installed systems. None of them is a Gutter Shutter price list.
| Data point | Figure | Type and date | Source |
|---|---|---|---|
| Manufacturer price list | Not published | Site pages archived March to June 2026 | guttershutter.com |
| Manufacturer positioning | A complete system “for the same or less money” than products added to old gutters | Manufacturer claim, no figures given | guttershutter.com, Q&A page |
| Dealer marketing | “We will BEAT LeafGuard and LeafFilter’s price by up to 50%” | One dealer’s advertising claim | BNW Builders, Facebook video post |
| Owner estimate | “Probably $30 to $40 per foot installed (in San Francisco area)” | Consumer-reported, July 2009 | Kevin Kelly, Cool Tools |
| National survey, gutter guard installation | $39.71 per linear foot average; $7,941 for 200 feet | Third-party survey of 1,000 homeowners, 2026 | This Old House, updated October 6, 2026 |
| National survey, by brand (200 feet) | LeafGuard $7,919; LeafFilter $8,344 | Third-party survey, 2026 | This Old House |
| Plain seamless gutter replacement | About $8 to $28 per foot installed | Roofing Brief cost guide, 2026 | The Roofing Brief |
Two points follow from that record. Gutter Shutter replaces your gutters, so a fair comparison is against a full gutter replacement plus a guard, not against a $2 per foot screen. And because the closest one-piece rival, LeafGuard, also replaces the whole gutter, its survey average is the most useful benchmark for a Gutter Shutter quote. Our LeafGuard cost breakdown shows how that price scales with home size.
How to sanity-check a Gutter Shutter quote
Convert any quote to a per-foot figure and set it against the two 2026 anchors above: plain seamless replacement and the national guard-system average. The table below is Roofing Brief arithmetic at those rates. It is a benchmark for reading a quote, not a Gutter Shutter price.
| Gutter length | Plain seamless replacement, $8 to $28/ft | National guard-system average, $39.71/ft | Basis |
|---|---|---|---|
| 100 ft | $800 to $2,800 | $3,971 | Length x rate |
| 150 ft | $1,200 to $4,200 | $5,957 | Length x rate |
| 200 ft | $1,600 to $5,600 | $7,942 | Length x rate (This Old House rounds to $7,941) |
| 250 ft | $2,000 to $7,000 | $9,928 | Length x rate |
To compare quotes correctly, ask each company to list linear feet of gutter, number and size of downspouts, extension lengths, fascia repair allowances, and old gutter removal as separate lines. Then divide the total by the gutter footage. Prices vary by region, roof height and fascia condition, so treat any single per-foot figure as a starting point.
Gutter Shutter pros and cons
Gutter Shutter’s strengths come from heavier materials and a fully covered trough; its weaknesses come from the reverse-curve physics it shares with every hood-style guard and from a dealer-only sales model. The table separates what the manufacturer’s documents support from what the design itself implies.
| Pros | Cons |
|---|---|
| 0.032-inch aluminum and brackets every 24 inches, per the manufacturer | No published prices; quote only after an in-home appointment |
| Fully covered trough sheds large leaves without a screen to clog | Reverse-curve noses can let water overshoot in very heavy runoff (see below) |
| 3 x 4 inch downspouts double the nominal outlet area of 2 x 3 inch | Replaces your gutters; you cannot keep sound existing gutters |
| Installs under the drip edge into the fascia, not under shingles | Full warranty certificate is not posted online; transferability not stated |
| Hood is a separate part that can be replaced without replacing the gutter | Hood-style profile is bulkier from the street than a flat mesh guard |
| Lifetime no-clog and 20-year paint warranties advertised | Workmanship and service depend on an independent local dealer |
Does Gutter Shutter work in heavy rain?
Gutter Shutter says yes: its Q&A states the system “has been designed and tested to handle the heaviest rainfalls” and that surface tension “isn’t affected by the amount or speed of the water.” The engineering record on reverse-curve hoods is more cautious. Very high runoff can carry water past the nose instead of around it, and Gutter Shutter publishes no inches-per-hour rating to judge the claim.
US Patent 7,104,012 (Bayram, granted September 12, 2006) describes the problem directly in its background on curved-nose guards: “during a heavy water flow, because of the large volume of water, much of the rain water will tend to fall off the roof from the curved end of the gutter guard, rather than flow around the curved end into the gutter.” The same patent notes that earlier fixes, such as bumps or S-bends that slow the water, still let much of the water fall off in heavy rain, and that ice and snow on the hood can defeat surface tension.
Gutter Shutter’s own recent patent filing acknowledges a related case. Its 2026 published application for a valley flow controller says water concentrated in a roof valley “can gain enough momentum flowing down the roof valley such that it will overshoot the outside edges of the intersecting gutter sections.” Flow reducers on the hood, which Gutter Shutter lists as a feature, are the same category of fix the 2006 patent describes: they slow water before it reaches the nose.
Competitors publish lab figures. Gutter Helmet says its hood was tested to handle 22 inches of rain per hour, and LeafGuard says its gutters handle 32 inches per hour. Those are manufacturer test claims under controlled conditions, not field guarantees. Our comparison of micro-mesh vs reverse-curve gutter guards covers how each style behaves when rainfall spikes.
Overshoot risk tends to rise in a few predictable places. Use this list to point the dealer at the spots on your roof that matter.
- Roof valleys that dump concentrated water onto a short run of gutter.
- Long, steep roof planes that deliver fast, deep runoff to one edge.
- Upper roofs that drain onto a lower roof and then into one gutter.
- Cold climates where ice can form on the hood, which the 2006 patent identifies as defeating surface tension.
Gutter Shutter BBB rating and complaints
The Better Business Bureau profile for Gutter Shutter at 60 Silvermine Rd, Seymour, Connecticut showed “Not Rated” and “Profile Under Review” when checked on October 9, 2026, with the notice “BBB’s information on this company is being updated, and no report is available at this time.” The same profile says the business has been BBB Accredited since September 19, 2022, and lists Larry M. Janesky as CEO.
Dealers carry their own BBB profiles, and those records differ by company. For example, Gutter Shutter of Greater Atlanta in Alpharetta, Georgia showed an A+ rating, BBB accreditation since November 30, 2022, and zero complaints in the last three years when checked on October 9, 2026. BBB ratings change as complaints are filed and resolved, so look up the specific dealer that will install your gutters, not only the manufacturer.

Gutter Shutter vs LeafFilter vs LeafGuard vs Gutter Helmet
These four names come up together because they are all professionally installed, lifetime-warranted systems sold through in-home appointments. They differ most in what gets installed: Gutter Shutter and LeafGuard replace your gutters, while LeafFilter and Gutter Helmet go on top of existing gutters. Every row below comes from each brand’s own website as published in 2026.
| Brand | Guard type | What gets installed | Install model | Warranty, as each brand states it | Published rain claim | Source |
|---|---|---|---|---|---|---|
| Gutter Shutter | Reverse-curve rolled hood, separate from gutter | New 6-inch seamless aluminum gutter, hood, 3 x 4 inch downspouts | Independent authorized dealers | Lifetime no-clog; 20-year paint; no-sag, no-pull guarantee | None published | guttershutter.com |
| LeafGuard | Reverse-curve hood formed as one piece with the gutter | New one-piece seamless gutter system | LeafGuard installers and dealers; product made by Englert | “Guaranteed not to clog for as long as you own your home, or we will clean your gutters for free”; lifetime ScratchGuard finish warranty, transferable, 50-year prorated for later owners | 32 inches per hour | leafguard.com |
| LeafFilter | Micro-mesh in a u-PVC frame | Guard on existing gutters (gutter replacement also offered) | LeafFilter North installers | Lifetime transferable warranty | None published | leaffilter.com |
| Gutter Helmet | Reverse-curve hood with 3/8-inch water opening | Hood over existing gutters | Certified installers and dealers | Performance transferable lifetime warranty | 22 inches per hour | gutterhelmet.com |
The deciding question is usually whether your existing gutters are worth keeping. If they are sound, correctly pitched and well fastened, an over-the-gutter guard avoids paying for new gutters. If they leak, sag or are undersized, a full replacement system like Gutter Shutter or LeafGuard solves both problems in one job. Our LeafFilter review and Gutter Helmet cost guide cover those two brands in more depth.
Is Gutter Shutter right for your home?
Gutter Shutter fits homes that need new gutters anyway and see heavy large-leaf debris. It fits less well where fine debris dominates, where roofs dump concentrated valley water, or where existing gutters are in good shape. Use this table to match your situation to the type of system that usually suits it.
| Your situation | Usually the better fit | Why |
|---|---|---|
| Old gutters leak, sag or are 5-inch on a large roof, plus heavy oak or maple leaf fall | Full replacement system with a hood (Gutter Shutter or LeafGuard) | Solves capacity, fastening and debris in one job |
| Existing gutters are sound and well pitched | Guard over existing gutters (micro-mesh or hood) | Avoids paying to replace working gutters |
| Mostly pine needles, seed pods or shingle grit | Micro-mesh guard, or ask about Gutter Shutter’s pine needle design in writing | Fine debris is where mesh tends to outperform open hoods |
| Roof has deep valleys or long steep planes | Any system, with the dealer’s specific valley plan in writing | Concentrated runoff is the classic overshoot point for hoods |
| Budget is the main constraint | Plain seamless gutters plus a mid-priced guard | Premium all-in-one systems sit near the top of the price range |
| You may sell the home soon | Whichever brand states transferable warranty terms in the certificate | Transfer terms affect resale value of the warranty |
How the Gutter Shutter buying process works
Gutter Shutter sells only through local dealers, and the website routes every visitor to a zip code lookup and a free estimate request. The steps below follow the process the manufacturer and its dealers describe, with the checks worth adding at each stage.
- Enter your zip code on guttershutter.com to find the authorized dealer for your area, then look up that dealer’s BBB profile and state contractor license.
- Book the free in-home estimate. Expect the representative to inspect your current gutters, fascia and roof edge and to measure the linear footage.
- Ask for an itemized written quote: gutter footage, hood type (standard or pine needle), number of downspouts, extension lengths, fascia repairs and removal of old gutters.
- Ask how the dealer handles valleys and steep roof planes, and get any valley diverters or splash guards written into the quote.
- Collect the full warranty certificate and confirm who backs each warranty and whether it transfers.
- Get at least one competing quote for a full replacement system and one for a guard on your existing gutters, then compare per-foot totals.
- On install day, check that brackets are fastened into the fascia and that the hood sits under the drip edge, not under the shingles. Gutter Shutter says its system installs in one day.
Gutter Shutter: the bottom line
Gutter Shutter is a heavy-duty, dealer-installed replacement gutter with an integrated reverse-curve hood. Its published specifications, 0.032-inch aluminum, 6-inch gutters and 3 x 4 inch downspouts, sit at the strong end of residential aluminum systems, and the manufacturer advertises lifetime no-clog and 20-year paint warranties.
The open questions are price, warranty fine print and heavy-rain behavior. The company publishes no prices, does not post its warranty certificate, and publishes no rainfall rating, while patent literature, including its own 2026 filing, documents overshoot where runoff is heavy or concentrated. If you need new gutters and have large-leaf trees, get a Gutter Shutter quote alongside a LeafGuard quote and an over-the-gutter guard quote, and compare them per foot with the warranty certificates in hand.
Gutter Shutter FAQ
Is Gutter Shutter any good?
Gutter Shutter is a well-built system on paper: 0.032-inch aluminum, 6-inch seamless gutters, 3 x 4 inch downspouts and brackets every 24 inches, per the manufacturer. It sheds large leaves well because the trough is fully covered. Like other reverse-curve hoods, it can let water overshoot in very heavy or concentrated runoff, and results depend on the local dealer’s installation.
How much is a Gutter Shutter?
Gutter Shutter publishes no prices; costs come from an in-home dealer estimate. For context, This Old House’s 2026 survey put professionally installed gutter guard systems at $39.71 per linear foot on average, and LeafGuard, a comparable full-replacement system, at $7,919 for 200 feet. A 2009 owner estimate put Gutter Shutter at $30 to $40 per foot in the San Francisco area.
What are gutter shutters?
Gutter Shutter is a brand name, not a generic product. It is an all-in-one system of new seamless aluminum gutters with a rolled hood on top. Rainwater follows the curved nose of the hood into the gutter by surface tension, while leaves and twigs slide off the edge. It is made by Gutter Shutter LLC and sold only through authorized dealers.
How long has Gutter Shutter been in business?
Gutter Shutter says it was founded in 2003. Gutter Shutter LLC is headquartered in Seymour, Connecticut, is part of the Contractor Nation network founded by Larry Janesky, and has held BBB accreditation since September 19, 2022, according to its BBB profile. The company announced new dealers as recently as June 2026.
Is Gutter Shutter still in business?
Yes. Gutter Shutter LLC announced new authorized dealers in Tennessee, North Carolina and Georgia in March 2026 and in northern Indiana in June 2026. Individual dealers are independent companies, and some local businesses using the name have closed, so confirm the status, license and BBB record of the specific dealer quoting your home.
Is Gutter Shutter better than LeafGuard?
They are close rivals. Both replace your gutters with seamless aluminum and a reverse-curve hood. Gutter Shutter uses a separate, replaceable hood on a 6-inch gutter; LeafGuard forms gutter and hood as one piece and publishes a 32 inch per hour rain claim and a posted warranty certificate. Compare written quotes and warranty certificates from both before deciding.
Can Gutter Shutter be installed on existing gutters?
Generally no. Gutter Shutter is sold as a complete system of new gutters, hoods, brackets and downspouts, and its Q&A argues against keeping old gutters. If your current gutters are sound and you only want debris protection, an over-the-gutter guard such as a micro-mesh screen or a Gutter Helmet hood is the more direct comparison.
