The only thing that has worked!

My house is surrounded by trees...pines, oaks, maples. My gutters and downspouts clogged continually. I purchased gutter guards that fit atop the gutters, but the rain just slid across them and waterfalls down the other side. I purchased gutter brush a few years ago and I don't have to worry now. Everything flows smoothly. Yes, every now and then they need to be taken out and shaken to clean them, but it's been 3 years and they are still doing the job without me touching them. So simple, yet so effective.

I could not have said it better! Thanks! (we love pictures of smiling people and Gutterbrush too)

Expect them to work fine, neighbor has an oak tree that fills my front gutters, will be an interesting test as oak leaves have hooks that catch on everything.

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.

Thanks very much for coming back to GutterBrush after trying other solutions! GutterBrush is coming up on 21 years! 888-397-9433

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.
