Gutter Covers, Screens and Mesh

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

🚫 Debris Disrupts Water Flow – Leaves, pine needles, and pollen pile up on gutter screens and covers, forming a barrier that causes rainwater to flow over instead of flowing into your gutters.

💦 It’s Not a Defect—It’s the Design – Even professionally installed micro-mesh and screen guards get dirty and become a ramp sending the water past the gutter, especially in heavy rain.

😩 Expensive & Frustrating – Many homeowners invest thousands in gutter covers, only to find their gutters still overflow when debris builds up.

🔧 More Maintenance, Not Less – To keep screens working, regular cleaning is required, often meaning more time on a ladder—defeating the purpose of a gutter guard.

✅ GutterBrush is the Better Solution – Instead of covering gutters and trapping debris on top, GutterBrush fills the gutter, keeping water flowing while preventing gutter clogs and overflow—no screens, no frustration, just reliable protection.

They have worked well at my house

They have worked well at my house. Have not had a gutter blockage in 4 years and it was a constant problem before as we live in an oak forest!
My leaves at home are mostly oak. i just installed the brushes at work where the pine needles where may be more of a challenge. However its very difficult to clean out the gutters there so we hope the brushes perform well there as well. Not very expensive and super easy to install. Cheers

So far, so good!

I purchased these gutter guards during the time that there a very few leaves falling and little rain, so they haven't been put to the test yet. I can say that customer service is spot on and so is delivery. Installation is very easy (so far, as I'm not finished yet). If I have a chance, I'll review later after we have heavy rains with lots of falling leaves.

Awesome Product for Apartment Patios

This is an awesome product, but I didn’t use it for traditional gutters. I live in a ground floor apartment. The gardeners are constantly blowing leaves into my patio from the small opening underneath the patio wall. So I placed the brushes under the wall. Perfect! Leaves can’t come in, but water can drain out. Thank you, thank you, thank you!
