Other Gutter Guards

Gutter Screen Covered With Leaves and Pine Needles. Water overflowing past gutter

🚫 Other Gutter Guards get dirty and restrict the gutter often sending the water past the gutter entirely!

💦 Try To Keep Every Spec of Debris Out and You End Up Keeping The Water Out Too - Dont over spend - read the reviews!

😩 Many Gutter Guards Cost a fortune and do not work requiring maintenance too frequently anyway.

✅ GutterBrush Is Better - Just fill the whole gutter. No other gutter guard accepts rain water as well as GutterBrush. Water follows the bristles into the gutter.

Went back to Gutterbrushes again

We had Gutterbrushes for years, but eventually they broke into smaller pieces, probably partly from banging them too hard on the side of the ladder. (a big sycamore over the house sheds a lot of stuff) Tried a metal gutter cover, but it didn’t work as well and the winter ice pushed them off so we’ve gone back to Gutterbrushes.

Success for 2”alumawood gutter

I finally found something that’ll work for my 2 inch wide Alumawood patio gutter. There really isn’t anything else available for such a narrow gutter. Gutterbrush is the only company that offered a product that works!
Thank you, Gutterbrush.

Ladder-Max is a winner!

The 19” standoff of Ladder-Max allowed me to SAFELY remove, refurbish, and re-pitch the 6” half-round gutters on my home. The gutters rest on brackets and are held in place with wire clips. Ladder-Max’s maximized clearance allows me to lift the gutters off the brackets and bring them down safely on the inside of the ladder’s pitch. Love it!

Does the Job

We have had good luck with ours, and we just added to them to the patio cover gutter, we did not realize that the patio gutter had filled up with debris and mud and had started a weed garden in the gutter, so we will be adding them up there, hoping this will help, but regarding the ones we have had in the house gutters, we can go about 2 years with out cleaning, yes some debris will collect but not like before without any protection, we find them helpful and easier to maintain

As Advertised!!!!

Simple to install and the product was as advertised. No surprises or disappointments. In today’s world of cyber shopping, that is refreshing. I will be purchasing more to do the rest of the gutters.

Repeat customer of GutterBrushes

I have previously purchased The GutterBrush 5 inch Gutter Guards for part of my gutters years ago. When I was replacing my roof and gutters this summer, I removed the previous GutterBrushes and sprayed them off and gave them a good shake and they were good as new. I purchased additional GutterBrushes to finish all my new gutters. And they were quick and easy to install.

Special application for very small Greenhouse gutters

Special, very small size worked for small gutters on greenhouse. Easy to install and cut to length. Only in use for one Fall "leaf" season and seems to work well.

6 INCH GUTTER GUARD - 6 FT. (5.25 IN. DIA.) TRIAL PACK
Easy install

I’ve installed various gutter guards over the years, wire mesh, aluminum and plastic. Without a doubt these are the easiest install possible. I have high confidence that they will stay in place, not be bothered by birds or limbs. I also believe they will be easy to clean should leaves impale themselves.

Gutter Guard Sizes, GutterBrush Questions

6 Gutter Guard Brush Sizes, Which One Is Right for Me?

Fill the width of the gutter with one of the 6 sizes. Fill the width of the gutter without overly compressing the bristles. A raised bristle profile may be desirable but is not always necessary or possible. Check out this page and see your gutter style at our "How To Measure page "

Yes! Whether it is a standard k style residential gutter, oversized 6 inch gutter, metal roof gutter, commercial gutter or a custom gutter, one of the 6 GutterBrush sizes will fit and solve your gutter problems. fromRe 2.25" diameter to 8 inch diameter

Does GutterBrush last a long time out in the gutter?

GutterBrush has been sold since 2004 and it lasts a very long time out in the gutter. It is made of lang lasting thick UV protected bristles and a galvanized steel core. GutterBrush comes with a 10 year material warranty but it lasts far longer than that.

Do all gutter guards require maintenance to keep flowing?

Yes, those who work outside on roofs and gutters know that all gutter guards out in debris areas will need maintenance in order to keep flowing. There is no such thing as a maintenance free gutter guard and people who overspend often have major disappointment when the complicated device becomes a water ramp that sends the water past the gutter.

Can GutterBrush be cleaned and renewed to start over?

Yes, that is the wonderful thing about a clog protection system that is easy to install and requires no fastening. If necessary, GutterBrush is easy to renew. Just remove some or all of the brushes, bang them on a hard surface to get the debris to drop out, clean the gutter and reinstall renewed and ready to start over fresh.

How can I learn more about How GutterBrush Works?

Visit this page to read more information and details about How GutterBrush Works.

When will my GutterBrush require maintenance.

Every gutter is different based on different conditions like the type of gutter, height of gutter, height of trees, prevailing wind patterns, types of trees, slope of roof etc. Some gutters go many many years without needing maintenance and others require maintenance more frequently. All gutter guards require maintenance so get one that is fast and easy to maintain, eventually. GutterBrush is easy to maintain and renew.
