Great stuff gutter stuff

Came quickly, installed easily, I think I’m going to buy some more for another house I have.

Good Customer Service

Since it has not rained yet since I installed the GutterStuff Pro gutter foam on my house a little over a week ago, I cannot yet attest to the functionality of the gutter foam. But I am impressed with your customer service in quickly replacing several pieces of the foam that I received which were excessively coated with the protective coating which would definitely impede the water flow through them. Installation was relatively easy and straightforward.

Keeps gutters clear, but...

The water flow has been uninterrupted by debris - which is great. We live next to a 300,000 acre lake in a veritable forest. Our 6" Ogee gutters could be cleaned every 2 weeks from September to January if the goal was to keep them forever unclogged. I am trying this product on the front of my house. I am also installing new speed hangars at the same time because originally they were installed with 1.5" ring shank nails which has caused some negative slope. I must admit that removing and reinstalling the speed hangars make installing the gutter stuff. And the flow of water through the gutters has been great. My only complaint is that while most leaves flow right over the small twigs with a few leaves that seem to hang up in the foam. I feel like I have traded a functional problem for an aesthetic problem. The gutters can appear clogged and over flowing - but the gutters are clear and are functioning fine.
I will say that from my experience with other gutter guards, helmets, shields, etc. which I never want to own them again. This system seems to be working better and unlike gutter helmet I don't see a way for pin oak or other smaller leaves to migrate into the gutter space itself.

Michael, We recommend to occasionally brush or spray off GutterStuff to remove any twigs that get hung up in the foam. With a little occasional maintenance GutterStuff will perform at peak performance for years to come.
Love these things!

Thank you for your wonderful product and for sending it out so quickly! I'm about to order more now that I see how well these work and how easy they are to install. Thanks!

New Gutter Stuff

Arrived in good shape and installed. The coating must have been applied just before boxing up to ship. There were "run off" stains inside the card board box and the coating was uneven on a number of pieces Hopefully, it will work ok.
