Gutter Repair and Replacement FAQs, answered by experts

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.

Yes. Excessive pitch in gutters can cause water to flow too rapidly, leading to a decrease in the gutter's water-holding capacity; consequently, during heavy rainstorms, water may awkwardly splash outside the gutters. Ideally, you should aim for a quarter-inch of gutter slope for every 10 feet of gutter run. However, it's important to note that this guideline may vary depending on your home's structure and the type of gutters being installed.

Downspouts channel water from your roof and gutters into the ground following a specific route so water doesn’t accumulate around your house’s foundation. Without a downspout, the standing water will wash away material and disrupt the soil, leading to foundation erosion. The standing water will also form ice around your house during cold weather, causing a safety hazard.

How long hangers last will depend on what gutter material they’re made from, but generally you can expect to get at least 10 to 15 years from them no matter what they’re made from. But don’t wait for them to break to give them a checkup. Inspect this part of your gutters on a yearly basis, and make repairs at the first sight of damage.

Yes, gutter repair is almost always worth the investment. Some homeowners believe that gutter repairs are only to improve the home’s curb appeal, but gutters play a pivotal role in protecting your foundation from damage and structural instability, and they also prevent water damage to your soffits, fascia, roof, and exterior walls. You will pay an average of around $400 to have your gutters professionally repaired, but it’s worth it even for the peace of mind of knowing that one of your largest investments is adequately protected from the elements.
