Why GutterBrush Downspout Guards are THE BEST

GutterBrush is larger with more surface area to keep downspouts protected longer without clogging or requiring cleaning. Wire basket downspout strainers are too small so they fill up, clog, and require cleaning way too soon. GutterBrush goes far longer!

Fill The Whole Gutter - BEST RESULTS

Our downspout guards are the best! Buy them here! But here's a tip! Fill the entire gutter for even better results. GutterBrush sells footage packs with 3 foot lengths. Fill the entire gutter and leave it in place for the easiest DIY way to stop gutter clogging. GutterBrush is an easy gutter guard system. Protect downspouts or fill the whole gutter!

All GutterBrush Sizes - 3 foot lengths

Downspout Protectors and Gutter Protection

18 inch lengths are the best gutter downspout guards because they are larger than downspout strainers with more surface area so they protect longer.

If you like 18 inch lengths, try a 3 foot length for more longevity or better yet, fill the whole gutter for the easiest simple and effective gutter protection system that anyone can install. Just fill the whole gutter to solve gutter clogging.

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

Thank you for explaining! Please come again! 888-397-9433 Gutterbrush

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.

Thanks for returning after YEARS! 888-397-9433 GutterBrush!

Downspout Guards

Downspout guards are necessary to keep gutter debris out of the downspout elbows because the downspout elbows are susceptible to clogging. People often buy a downspout wire strainer which is traditionally a simple fix whereby the homeowner or business owner simply climbs the ladder and stuffs the wire strainer into the gutter outlet opening. These downspout guards and downspout Protectors come in all sorts of shapes and sizes but with one problem which is that they are too small and they can not filter out enough debris without clogging or needing cleaning or maintenance. I have dealt with this for customers myself where all of a sudden someone needs to keep debris out of the downspout but the cure becomes worse than the problem. The mere activity of shoving a strainer into an outlet tube can cause required cleaning every 2 weeks which is far too frequently and the reason for such is because even a small handful of gutter debris can overcome and clog small strainers.

Downspout Wire Strainers

Downspout wire strainers are just too small so they fill with debris too quickly and they clog and cause the rain water to pour over the side of the gutter. Continue reading below to learn why downspout wire strainers will keep debris from clogging the downspouts, but they are just too small and so they clog too frequently.

Better Downspout Guard Because It Is Larger

The logic is simple. In order to keep downspouts clear and decrease the number of times you need to get out the ladder and climb up there, you need a larger strainer that can provide the maximum downspout protection filtering more leaves and debris while still allowing rain water to flow through and out the downspouts. Larger is better and more surface area is the best. That's why our 18 inch downspout guards are better than wire basket downspout strainers and other downspout Protectors. Our 3 foot sections are even better in fact the more you add, the longer the amount of time you can go without maintenance. Fill the entire gutter for best results, and clog protection. Fill the whole gutter and see how long you can go without having a clog and without having to perform gutter cleaning. You will be amazed. Click here for how it works. GutterBrush solves clogging and if or when it ever needs maintenance, it is easy to remove, bang out, clean the gutter and start over completely renewed.

Downspout Clogging

Downspouts are susceptible to clogging because the gutter elbows usually have restrictions, fasteners and less slope. Stop downspout clogging by laying Gutterbrush over the gutter downspout opening. The more you use over the outlet tube, the better the results will be.

Downspout Enters Ground Drain Pipe

GutterBrush is a fantastic solution if you need to keep gutter leaves out of your downspouts and more important if you need to keep debris out of your storm drainage which is buried in the ground. It is very important to keep in ground storm drainage pipes clear because if they clog you may have to bear the expense of digging them up and replacing them. Even the cost of roto rooter is expensive so you might as well use GutterBrush downspout guards and Gutterbrush gutter guard system to both keep the gutter from clogging and also keep the debris and gutter leaves out of the in-ground drainage pipes. Whenever downspouts or leader pipes enter the ground, it is Important to not let the gutter debris enter the ground. Keep the debris out by purchasing and installing the correct size GutterBrush.
