GutterBrush Gutter Guard Information

▶ Click here to watch a 30 second video "What Is GutterBrush.  The GutterBrush Gutter Guard system consists of filling the entire gutter with 3 foot lengths of self-positioning GutterBrush, and leaving them in place; the brush keeps debris out and keeps the gutter from clogging while the water flows between the bristles. No tools or fasteners required.   Each length of GutterBrush is a flexible bottle brush with stiff black bristles.  For a more technical description, the GutterBrush Gutter Guard is a cylinder shaped, twisted in wire, polypropylene black brush with double UV protection. The center core of GutterBrush Gutter Guard is 12 Gauge Galvanized Steel. Available in 5 diameters ranging from 3.25 inches for small specialty gutters up to 8 inches for large Industrial gutters. GutterBrush Gutter Guard is a simple, easy, effective, and affordable way to install year round gutter protection.

When placed in a rain gutter or eavestroughs, stiff Black GutterBrush Gutter Guard bristles fill the entire rain gutter or eavestroughs from "end to end" and provide year round gutter protection by preventing leaves and other debris from accumulating i­n the rain gutter and impeding water flow. Water continues to flow freely between the gutter guard bristles,  and down the drain pipe or downspout.  ▶ Click here to view a 33 second video of how the debris can no longer "clump, flow and clog".

Even small amounts of small debris can clog your gutter and GutterBrush is the simplest easiest and fastest way to keep gutters from clogging without spending a fortune.  No tools or fasteners required for installation.  Click here to see a short video on how only small amounts of debris can clog your gutter.  Click here to view a 56 second video about the simplicity of GutterBrush.  Rain gutter helmets, covers, gutter screens, meshes, leaf filters, reverse curves, perforations, louvers, fine screens, slits, slots & combinations of the above have never done what the GutterBrush simple gutter guard can do: protect your rain gutter or eavestroughs and keep debris out of the rain gutter channel all year round while keeping the water flowing. Helmets, covers and screens are very expensive and they eventually do clog requiring expensive disassembly. They are notorious for creating a flat mat of debris laying on top, which causes the rain water to bypass and miss the gutter altogether.   The GutterBrush Gutter Guard eliminates clogged and overflowing rain gutter systems that contribute to rot and water damage of the soffit, trim, sills, landscaping, walls, fascia boards, foundation, basement, and crawl spaces. Other systems are very expensive and complicated to install, however GutterBrush is self-positioning and installs quickly and easily with no tools and no fasteners making GutterBrush the best value.  Anyone who works on ladders or cleans gutters, can install GutterBrush quickly and easily; and if necessary, GutterBrush is easily maintained and renewed for long lasting continued performance.

If debris rests on your roof, the same may be the case with GutterBrush until the wind blows it off so don’t panic! Leaves and debris may be caught in the top of the gutter guard bristles, but individual pieces of suspended debris can't cause a clog because it can not "clump together and flow to clog".  Click here for a 33 second video.   With continual cycles of rain, sun and wind, combined with the high level of airflow through the GutterBrush Gutter Guard, most debris either dries out and blows away or self-composts and breaks down into small particles that wash down the rain gutter. Water will continue to flow through the gutter guard and your rain gutters or eavestroughs will not clog!  GutterBrush keeps the gutter flowing.  Eventually, at some point it is very easy to maintain and renew.  It keeps in-ground drainage clear too.

With pine needles, GutterBrush keeps the gutter from cloggingClick here to view a 1 minute video about small debris like pine needles and maple seeds. Although pine needles, maple seeds and other small debris may become caught in the top of the GutterBrush they remain suspended and can no longer clump together and flow down the gutter creating a clog. Natural cycles of sun, rain, and abundant airflow help blow the debris from the gutter guard or promote rapid decomposition and break-down. Your rain gutters will remain protected and water will continue to flow.  Individual pieces of small debris can not create a clog themselves, unless they are allowed to clump together, which cant happen with GutterBrush. Additionally,  the bristles are directionally leading towards the center of the gutter and are directing the water into the gutter and not past the gutter.  Eventually, at some point, maintenance is easy by just removing the brushes and shaking them out, clean the gutter and reinstall completely renewed.  Click here for an article about GutterBrush and Pine needles .

The K-Style gutter is the most commonly produced gutter style.  Click to view a 49 second video about the K-Style gutter.  Considered a "standard gutter", view pictures of the K-style gutter at the top of our "Fit My Gutter" page.  It is produced in custom long lengths roll formed out of the back of trucks or trailers in all neighborhoods in the USA. GutterBrush is designed and sized to fit perfectly in K-style gutters.  This style of gutter, years ago was named after the upper portion of the script written K, because the curves of the gutter's face resemble the curved nature of the upper-half portion of the capitalized letter K when written in script.  GutterBrush also fits the ever so popular Fascia style gutter.   The K-style gutter is also often referred to as an OG or Ogee or K-Ogee.  OGEE is a word that often refers to any  architectural design that incorporates a double curve like an "S" which curves in both directions.   With respect to a K-style gutter,  the curve of the face of the gutter reverses direction like an "S" curve and resembles the aesthetic appeal of the double curve on a crown molding.   GutterBrush fits into all size and style gutters and functions well because it is, by itself, a protected flow channel.

Why GutterBrush GutterGuard

All rain gutter protection systems are not the same. Most are extremely expensive requiring professional installation costing from $15. per foot to as much as $ 30. per foot. Many of them create a flat "debris covered" shelf that causes ice dams and causes water to backup over the fasca or back -up under the roof shingles and leak into the building. Debris covered screens and covers are notorious for actually causing the rain water to skip off the device, miss the gutter entirely, and cascade over the side. The GutterBrush Gutter Guard is different.  GutterBrush does not intersect or even touch the roof. It comes in different sizes and lengths to accommodate different rain gutters, sizes and configurations, and can easily be inexpensively installed by the homeowner, a handyman, landscaper, painter, contractor of choice; or by a GutterBrush contractor found on our "find an installer" web page.   The key is the speed and ease of installation which requires no tools or fasteners and keeps the cost down.  All gutter guards require maintenance and GutterBrush is easy to maintain too. The GutterBrush Gutter Guard is the best rain gutter protection system on the market because it is the best value and will prevent rain gutter clogging; and will also prevent entry to birds and animals. Other GutterGuards mislead by claiming that you will never have to clean your gutters again.  All gutter guards require maintenance and GutterBrush is the easiest to maintain. At some point if necessary, just remove GutterBrush, bang the debris out, clean the gutter and reinstall completely renewed.

Yes, the first thing to do, is determine which size or diameter of GutterBrush will fit your particular gutters best. Visit our "Fit My Gutter" web page or call 888-397-9433 for assistance.  GutterBrush comes in 5 different sizes or diameters to fit all of the most common size gutters.  First, determine which size of GutterBrush is the right fit for your gutters. Depending on your size of gutter, we offer GutterBrush in different box length increments. Based on your total linear footage of gutter or eavestroughs, you can order a combination of these box sizes to meet your needs. Finally, the GutterBrush Guys recommend ordering an additional 6 to 10 feet over your measurement to accommodate different rain gutter configurations, bends and other slight product waste during installation.  All GutterBrush orders are fulfilled predominantly with three foot lengths which are inserted into the gutter one after the other filling the entire gutter from "end to end".  Each box also has a few 18" lengths so you can choose a smaller piece when you get to the end....and you do not have to cut GutterBrush because you can fold it back into itself to create that last piece.

The simple design, self positioning, and quality manufacturing allows the GutterBrush Gutter Guard to be installed quickly and hassle-free. The GutterBrush Gutter Guard system is the best solution because it is based on a simple premise that prevents your rain gutter from clogging combined with the fact that the direction of the bristles is actually into the gutter.  Other systems create a "flat horizontal plane" that causes water to skip past, but GutterBrush's raised profile actually causes the bristles to draw water into the center of the gutter for better performance. There is no complicated assembly of the GutterBrush Gutter Guard system, no touching of roof material, no holes or fasteners are placed in or on your home’s roof, fascia or rain gutters, and it stays in your gutter year round. This means the GutterBrush can be purchased and installed for a small fraction of the cost of other, more complicated rain gutter protection devices. Plus, if the GutterBrush Gutter Guard ever requires maintenance, the system is easily and quickly removed, renewed, and re-installed with no damage to your valuable home. The simple yet incredibly effective design of the GutterBrush Gutter Guard combined with the ease of installation, allows us to pass considerable savings along to you.

GutterBrush Gutter Guard Installation

GutterBrush comes in five different sizes or diameters to fit the most common size gutters. Within each GutterBrush size, multiple box sizes or lengths are available.Our products are as follows.
Small for 4 inch gutters (actual brush diameter is 3.25")
Standard for 5 inch gutters (actual diameter is 4.25")
Oversized for 6 inch gutters (actual diameter is 5.25")
Extra Large for 7 inch gutters (actual diameter is 6.5")
Industrial for 8 inch gutters (actual brush diameter is 8")
The most common size of GutterBrush is Standard for 5 inch gutters. The most common Style of gutter, by far, is the K-Style gutter. If you have a K-Style gutter, you simply measure your rain gutter across the top horizontally from the back of the rain gutter (at the fascia) to the outermost tip of the gutter. 5 inch = Standard (most common) , 6 inch = Oversized. To see pictures of "How to Measure", click here go to our "Fit My Gutter" page. If you have a K-style gutter, simply identify which size you have and order the appropriate GutterBrush size and footage. If you have some other size or style of gutter, residential sizing samples and commercial sizing samples ( 2 different sample boxes) are available for a portion of our sample cost. The residential sizing sample box (smp-res) contains 6" length samples of each of our 3 smallest residential size products for $ 7.95. The commercial sizing sample box (smp-com) contains 6" length samples of each of our 3 largest commercial size products for $ 9.95. Once again, if you have a K-style gutter you should not need sizing samples, however if you have some other style of gutter, the sizing samples box enables you to receive samples of 3 different sizes so that you can actually check the fit of each to determine the best most optimal GutterBrush product for your gutters.

GutterBrush's Fit Criteria: The best most optimal performance is achieved when the brush fills the gutter as much as possible without overly compressing the bristles.  Additionally it is also desirable that the brush creates a "raised profile"  or "crowns" or extends out the top of the gutter about an inch or two.  The raised profile increases surface area and also allows that debris that may lay on the brush is up higher than the sides of the gutter so that the wind can purge.  Since GutterBrush was originally designed for K-style gutters, the fit is always perfect when you purchase the right size.   Other style gutters can be fit by using the most optimal size of GutterBrush that follows the GutterBrush Fit Criteria.  As the Fit Criteria States, it is desirable that GutterBrush fills the gutter and extends or "crowns" out the top to create a raised profile, however with gutters which have a width that differs from the length, it is not always possible to fill the entire gutter and create the raised profile.  In such cases, an on-site decision can be made with sizing samples to determine the most optimal fit.   GutterBrush will work fine even if it does not fill the entire gutter or if it does  not necessarily extend or "crown " out the top creating the raise profile.   While these characteristics are desirable to create the best performance, GutterBrush works just fine when it does not necessarily have all of these characteristics because GutterBrush is, in itself, a protected flow chanel.  

No. If your rain gutters and downspouts are properly installed, in good condition with an adequate number of downspouts, the GutterBrush can be installed inside your existing clean rain gutters with no tools or fasteners needed; just fill the entire gutter from "end to end".    There is also one other GutterBrush advantage:  If you do choose to purchase new gutters and downspouts, GutterBrush is very inexpensive because when new gutters are being fabricated, GutterBrush can be inserted into the new gutter while it is being fabricated from the ground, thereby saving a step because the gutters can be "hung" with GutterBrush already inside.

No! The GutterBrush Gutter Guard does not need to be cut in fact no tools are necessary. The GutterBrush Gutter Guard ships in two lengths, 3 foot and 18 inches. When you come to the end of your rain gutter, if a section is too long, simply bend or fold the excess gutter guard brush back into itself to achieve the desired length. (installation tip: if the folded piece is a little bulky, install it and then spin it 1/4 turn so that the gutter contains the bulky portion.) GutterBrush gutter guards can also be bent around corners for a customized fit without cutting.

Yes! GutterBrush Gutter Guard is easily installed and will not interfere with or even touch roof surfaces such as Asphalt, Fiberglass, Cedar Shake, Slate, Tile, Rubber, Metal or other kinds of roof. It also works in combination with any rain gutter type including: K-Style, Half Round, Fascia Style, Copper, PVC, Aluminum, Galvanized or Stainless Steel. * GutterBrush Gutter Guard may be slightly more visible when used in 1/2 Round style gutters, but performs very well. Any good roofer will tell you that the goal is to get the water controlled and off of the roof as quickly as possible which is why it is insane to install a gutter guard that even touches the roof, decreases the slope of the roof, or creates a horizontal shelf aimed at the top edge of the fascia. Gutter Guards can burden roofs and even cause leaks by creating a "shelf" or barrier that in high winds or ice can cause water to be directed up under roof shingles, or back-up over the fascia and into the building. Gutters are not absolutely necessary on a roof, but when connected
to a roof they can be the cause of bad roof leakage.

Our record of customer satisfaction is unparalleled and we will do whatever it takes to protect that record.

Your rain gutters will remain clear and flowing after the installation of GutterBrush Gutter Guard.   Gutters can continue to flow freely even with debris lodged in the bristles.  The debris and the bristles actively gather and direct water down into the gutter; however, if you ever do need to address gutter debris or a trouble spot, renewing your GutterBrush and rain gutters becomes as easy as removing a section of the GutterBrush Gutter Guard and giving it a quick shake or a brush with your hand or bang it onto a hard surface causing the debris to release; clean the gutter and then easily slide the GutterBrush back into place.  Other gutter solutions allow debris to flow within the gutter but not GutterBrush.  GutterBrush suspends any debris, therefore it now also becomes possible to perform minimal or partial maintenance to solve an issue.  GutterBrush customers also enjoy the fact that partial maintenance now also makes sense.

GutterBrush Gutter Guard Problems

GutterBrush does not touch or get fastened to the roof so it has no effect on the roof whatsoever.  Ice dams are typically the result of a combination of improper insulation and a lack of soffit ventilation resulting in unnatural melting or a  “warm roof”  which becomes susceptible to ice dams and daily worsening of the condition.  GutterBrush does not cause icing or ice problems as it is entirely confined to the gutter and has no effect on the roof. However, GutterBrush decreases gutter icing and improves the performance of the gutter in the winter.  What many do not realize is that snow causes gutter clogs in an unprotected gutter.  Without GutterBrush, snow causes clogged winter gutters during melting or rain, and then the gutter fills with water and freezes to a solid block of ice that evening. With GutterBrush in the gutter, the snow tends to sit only atop of the brush and the flow channel stays protected from outlet tube to outlet tube, so that during rain or melting, the water is capable of flowing out the outlet tubes and down the down spouts, so you get fewer occurrences of icing.   Day by day, the condition actually improves (rather than worsening)  because the melting water can flow out rather than making the ice larger during slow melting.  Additionally, the mere fact that the black bristles which are exposed absorb the sun's warmth and transfer that heat to the wire core accelerating natural melting.  Click here to go to our Winter Performance page and see pictures and learn more.   GutterBrush is compatible and can be used in conjunction with heat tapes or heat melting wires.   GutterBrush customers express a great decrease in ice and icicles.

Although we think our product is the best on the market, we also believe it best if you never see it working. The GutterBrush Gutter Guard is manufactured of the highest quality materials that contribute to its low-profile application that keeps your rain gutters clean while remaining almost undetectable from ground level. For example, in lower level gutters you may just see the tips of the Gutter Guard bristles and in rain gutters 10-12 feet off of the ground the Gutter Guard will not be visible.  In most gutters, the black bristles extend about an inch to an inch and a half above the edge of the gutter and due to the height of most homes, they are not visible because of the angle of the viewer looking upward.   In cases where the bristles might be visible, a dark dip edge behind the brush further acts to decrease detectability.  Samples can be acquired to set in your gutter and view.
