Having properly-working gutters to carry runoff water away from your home is very important in maintaining the integrity of your foundation. But even the best gutter system won’t accomplish its goal if the water pours out of the downspout next to the base of the home.

That’s why gutter downspout extensions are sometimes necessary. Affixing these products onto the ends of your downspouts can help guide the water

1. to a spot where it won’t pool near your foundation. There are plenty of different types of downspout extensions that are available, but here are the top five when it comes to customer reviews.
