Failing to clean your gutters can lead to serious and costly damage. When leaves and other debris cause blockages, water cannot drain properly and will overflow. This can lead to water pooling around your home’s foundation, causing basement flooding and structural damage. The overflow can also damage your roof, siding, and fascia boards, with the constant moisture promoting mold, mildew, and rot. The weight of wet debris can cause gutters to sag or break, while stagnant water creates a breeding ground for pests like mosquitoes and rodents. Additionally, runoff can damage landscaping or freeze on driveways and patios, causing cracks. To prevent these issues, it is recommended to clean your gutters at least once or twice a year.

Buried downspouts can freeze during cold weather as cold water runs through them. If you’ve discovered your downspouts are frozen, you can carefully pour hot water down the top of the downspout to defrost them. If that doesn’t work, you may need to dig your downspout back up. Avoid trying to break the ice from the exterior using a hammer as this can cause cracks and damage to your downspout.

To avoid freezing the future, consider adding a heating cable to the exterior, which can adjust heat based on the surrounding temperature.

The cost to install a downspout extension or reroute a downspout generally falls between $30 and $200. The final price depends on factors like whether you DIY the project or hire a gutter professional, the complexity of your gutter system, and the length of the new extension. A simple, above-ground DIY installation can cost as little as $30 for materials. In contrast, a more complex project involving professional installation and digging trenches for underground piping could cost over $1,000. This is still a significant saving compared to replacing your entire gutter system, which costs around $1,900 on average.

Absolutely—and lots of it. Overflowing water from your gutters can damage your siding and your roof. All of the moisture getting into the cracks and crevices of your home can lead to mold or mildew problems down the line. In addition, when water pools around your home, it needs a place to go—and sometimes it ends up inside the house, creating a very unwanted flood.
