Costco is a great place to turn to if you’re looking to save money but also get great quality, so it should come as no surprise that the gutter guards available from Costco provide some of the best value in the gutter guard industry.

You’ll need to install Costco gutter guards yourself, which will require some time and effort on your part, but the result is you’ll save even more on installation and get a product that works quite well on your existing gutters, even for smaller debris.

In this guide, we’ll review the gutter guards available from Costco. We’ll include information about how well they work, how easy they are to install, the overall cost and value and the warranty coverage that’s included.

Costco at a Glance

Costco is a great place for homeowners looking to complete DIY home improvement projects, as it carries affordable and easy-to-install home products that are available in 46 states. The gutter guards from Costco are suitable even for inexperienced DIYers, and they come with an outstanding warranty that makes them all the more appealing, especially given their low cost.

Unlike other home improvement stores that carry multiple types of gutter guards, Costco carries just one: micro-mesh gutter guards. This style is designed to allow water to flow neatly into your gutter system and down the downspouts while keeping virtually all debris from causing clogs. 

This includes large debris like pine cones and leaves as well as small debris like leaf particles and pine needles.

Costco maintains an A+ rating with the Better Business Bureau (BBB) as well as countless positive online reviews. As far as gutter guards go, the company’s warranty is excellent, provided you install the guards properly, and you can extend your warranty from 10 years up to an impressive 25 years, which is longer than many other DIY gutter guard solutions like GutterGlove and Amerimax.

Costco Gutter Guard Review

Gutter guards are essential for homeowners looking to protect their homes and home foundations with gutter systems and who also want to avoid having to get on a ladder and clean out the gutters several times a year. Costco gutter guards perform better than many other DIY options especially cheaper ones like foam and brush gutter guards.

In the sections below, we’ll include some detailed information about the gutter screens from Costco including how well they work, what they cost and how easy they are to install yourself.


Unlike some dedicated home improvement stores like Home Depot and Lowes, Costco offers just one brand of gutter guard: EasyOn Gutter Guard. These guards are available in two lengths: 24 feet and 100 feet, which is great for customizing your system to your specific home without having to buy large pieces that will go unused.

The gutter guards from Costco are also available in two different widths — five-inch and six-inch  — that are designed to fit standard K-style gutter systems. These choices will be suitable for most homes, although homeowners with other gutter styles may not be able to install these properly.

The gutter guards from Costco are made of durable stainless steel micro-mesh, so they won’t rust or get discolored with exposure to sunlight or moisture, and they won’t warp over time. The mesh is fine enough to catch just about any debris that falls or washes onto them, including pollen and pine needles, and there are thousands of customer reviews to back this up. The stainless steel is also more durable than aluminum gutter guards.

A unique feature of the Costco gutter guards is that they are UL-certified for rainwater harvesting, so homeowners who harvest rainwater for non-consumption uses can rest assured that these gutter guards won’t leach harmful chemicals into the water that passes through them.

How Costco Gutter Guards Work

The EasyOn Gutter Guards feature a fine mesh made of stainless steel that allows water to pass through for proper drainage but stops just about all debris from clogging your gutter system. These gutter guards have around 24,000 reviews, with most customers raving that:

  • They catch large debris like sticks and pinecones
  • They prevent small debris like pine needles from entering your rain gutters
  • They can handle large volumes of water
  • There is minimal splash-over that reaches your foundation

Of all DIY gutter guard options, the EasyOn brand from Costco is among the top-rated options in the industry.

Warranty Coverage

The Costco gutter guards come with a 10-year warranty for equipment, which is quite good for a DIY gutter guard option. However, you can register your gutter guards after installation to get the extended warranty, which is up to a staggering 25 years. 

This is the kind of warranty you typically see with professionally installed gutter guards — like LeafFilter and LeafGuard — so it’s outstanding for an affordable DIY option.

It’s important to keep in mind that you must install your gutter guards precisely according to the directions. Any changes or modifications to the gutter guards or signs of improper installation will void your warranty, so it’s important that you follow the directions as closely as possible.

It’s also important to remember that the warranty that comes with the EasyOn Gutter Guards is for the equipment only, so it only guarantees that you won’t experience product failure or breakage like warping, cracking or rusting. 

Unlike a professionally installed gutter guard system, you won’t get a performance warranty with these guards or the promise that gutter cleaning — if required after installation — will be paid for.

Costco Gutter Guard Installation

DIY gutter guards are a great option for homeowners looking for an affordable solution to clogged gutters, but, of course, they do require some time and effort on your part. The gutter guards from Costco are no exception, so you should be prepared to spend some time installing this product.

Generally speaking, the installation process is quite easy. The guards are designed to be installed on top of the gutters. The side closest to your roof gets tucked under the first layer of roof shingles (so you won’t void your roof warranty as long as you follow the directions), and the other side attaches to the outer edge of your gutters with the pre-applied tape and/or self-drilling screws.  

If you need to bend the gutter guards to fit your gutters, the side closest to your roof can be attached to the fascia.

Unlike other home improvement stores, Costco doesn’t offer the option of professional installation. You could purchase the guards and hire a third-party installer, but the process is simple enough for most homeowners to do themselves.

Lastly, it’s important to keep in mind that you may need additional equipment to install these gutter guards. Some things you may need include:

  • A metal-cutting saw
  • A drill
  • A sturdy ladder that can reach your gutters
  • Self-tapping screws (and/or exterior tape or adhesives)

Most DIYers should be able to install these guards in a day or two.

Costco Gutter Guard Cost

Costco’s EasyOn Gutter Guards cost between $2 and $2.50 per linear foot, depending on which width you get (5 inches or 6 inches) and the length you buy (it’s available in 24-foot and 100-foot options). 

These are a bit more expensive than the DIY gutter guards available from Home Depot and Lowes, but they are still far cheaper than professionally-installed gutter guards, which can reach up to around $7 per linear foot or more if you also need professional installation.


Costco is a nationwide company that operates in 46 states plus Washington, D.C. and Puerto Rico, so these gutter guards are available to most homeowners no matter where they live in the U.S. 

On the Costco website, prices include shipping and handling and descriptions note that the guards may be available for pickup in the warehouse for a lower price. There are additional delivery charges for destinations in Alaska, Hawaii and Puerto Rico.

Costco Gutter Guard Reviews

There are about 24,000 reviews for EasyOn Gutter Guards on, which is a testament to their popularity. The guards have nearly a five-star overall rating, which speaks to their effectiveness and high value-to-cost ratio. 

Some positive things commonly mentioned in the reviews include:

  • How quickly water can pass through the mesh
  • How much large and small debris the guards keep out of your gutters
  • How easy they are to install
  • How easy they are to return if needed
  • How seldom they need cleaning

Here’s a video from one reviewer:

One thing in particular that makes it into many of the reviews is how much more efficiently they function than other DIY guards. Many customers have had other DIY gutter guard options clog or cause spillover, especially during a downpour.

The reviews for Costco gutter guards suggest that spillover is almost never an issue, and some customers have mentioned that they have tested the guards with five-gallon buckets of water and hoses, and the results are almost always positive. These guards are commonly recommended by customers for areas that experience heavy or above-average rainfall.

One recurring issue commonly reported with these gutter guards is that they can form ice dams and icicles in the winter in colder climates. Unfortunately, this is the case with all types of gutter guards unless you buy heated ones that are suitable for below-freezing weather. EasyOn Gutter Guards have a facility for installing heat cables.

Below, we’ll include some of the positive and negative reviews of these gutter guards to give you a sense of what you can expect after you install them.

“Easy install. I used [the] screw-in method. Pieces overlap neatly. Using [a] metal saw I easily cut out about 4 inches of the aluminum sides near one end, then tuck the stainless steel mess of that end into the gutter’s end section. Works great despite heavy rain for the past 3-4 weeks. No overflow. It does catch pine needles poking into the mesh, so definitely need to use the brush at times. [I ended up replacing a] previous, more expensive brand that failed. I like the thin profile of this one as well.”

“I put them on the section of my roof that is under a white pine and a pin oak. Both these trees are dirty and have given every other gutter guard I have tried a problem. The white pine needles find a way to get stuck in the larger openings and the pin oak drops heavy sticky pollen pods in the spring. The fine stainless steel mesh has kept my gutters in perfect working order with no maintenance for two seasons. Installation is easy and I was finished in under two hours.”

— MrBooj via

“I’m a contractor, so I asked my gutter guy what is the best gutter guard system and he told me the best he had seen were the ones at Costco. At first [my customer] was very happy with the performance of the system until it came to winter time. I received calls from her that the gutters had icicles hanging from them. Come to find out that the fine mesh allows water to freeze up and block drainage to the gutters.”

— Mdpflueger via

Final Thoughts & Recommendation

If you’re looking to forego professional installation and prefer to install gutter guards yourself, the Costco gutter guards are some of the best options. These guards are a bit more expensive than the ones you’ll find at stores like Home Depot and Lowes, but they are super easy to install and come with an outstanding warranty that is extendable for up to 25 years.

Although the warranty doesn’t cover performance or guarantee, as some professional installers do, that your gutters won’t get clogged, most of the customer reviews for this product are overwhelmingly positive. 

The majority of homeowners who choose these guards are pleased with the water flow rate into their gutters and how well their gutters and downspouts are protected from all debris, from pine needles to large sticks.

Overall, we recommend Costco gutter guards if you’re looking for a high-quality gutter guard system that you can install yourself. With a day or two for the installation process and some time dedicated to cleaning the stainless steel mesh one to two times per year, the EasyOn Gutter Guards from Costco should serve you and your home quite well, saving you money while still offering ample protection from clogged gutters.
