Eavestrough Repairs and Preventing Downspout Blockages with Gutterstuff

Our latest house is two stories tall, with eavestrough at both levels. It's also situated close to many mature trees, and as I quickly found out, none of the downspouts were clear and working properly. In the summer we get oak seeds (double samaras) - some people call them helicopter seeds, and then in the fall we get leaves - lots of them.

My first season in the house I tried to alleveiate the problem by installing spherical downspout strainers on all the downspouts. These worked - for about 2 weeks. And then they become completely blocked with leaves and as the leaves rod, they gradually allow infiltration into the downspout. It was definitely not the solution I was looking for.



My second season, I went looking for a better solution. I considered the plastic or aluminum covers that you can purchase, however I was worried about two aspects - i) fit; and ii) performance - would water just sheet off the cover and overrun the eavestrough? It seemed like too much trouble to install, and would be finicky to fit.

I stumbled across a product called Gutterstuff in my local home improvement store - it's a black, open cell foam cut into a triangular shape, which stuffs into your eavetrough gutters making it impossible for helicopter seeds or leaves to get down into the gutter and block your downspouts. It looked like it would work - so I bought half a dozen pieces to try out on my eavestroughs. 

The triangular shape leaves the bottom free for water to flow to the downspout. The top surface is completely closed - preventing any leaves or seeds to get into the downspout. This is the "K Style" Gutterguard. There are other shapes available.

The open cell design allows water to flow through very easily.
Installation is very simple - the pieces are 4 feet long, and stuff underneath the nails or screws that hold your eavestroughs to your eaves. It cuts with scissors, and can be easily fit around corners or odd angles.

So - how does it work? Absolutely great! I haven't been up to clean out gutters by hand in 14 months now, and everything flows perfectly. No more overflowing gutters, no more water soaked brick, no more blocked downspouts. I find that leaves may land and rest on top of the gutters, but not for more than a few hours or a day. As soon as a little bit of wind hits the gutters, the wind will sweep the leaves off the top of the Gutterstuff keeping everything clear. Water sweeps right through the open cell foam, and does not splash or overrun the gutter. So far it's holding up well under the sun with no UV degradation.

If you have a problem with leaves and your eavestroughs, I highly recommend this product, it will work.
