"I had our front stoop and limestone steps replaced and repaired. Geni and his brother, Arjan, are so professional. My husband and I are so pleased with the finished work. Aside from that we also had them repair our front gutter and seal the back to prevent anymore leaks. We definitely recommend them to anyone."

Gutter Repair and Replacement FAQs, answered by experts

If you are experiencing minor issues with your gutters, such as a small leak or cracks in one or two sections, it makes more sense to repair the issue than to replace your entire gutter system. However, you may need to replace your gutters if they’re frequently detaching from your home or if you notice a buildup of mold or mildew in your basement.

If you don't repair your home’s gutter leaks, water or the gutters themselves can damage your home’s siding, roofing, foundation, and landscaping. Untreated leaks encourage mildew, mold, and rot, depending on the type of siding material. The foundation, chimney, window frames, and drywall can also crack over time, leading to costly repairs. 

If your gutters get overwhelmed every time it rains, adding an extra downspout is a solution. First, you'll need to decide where to add the downspout. If your current setup only has a single downspout, one option is to place a new one at the opposite end of the gutter. If you already have a downspout at each end, adding a third one in the middle can help to lighten the load. 

You can hire a professional to add a downspout yourself by cutting into the existing gutter and attaching the necessary parts, such as an outlet and brackets.

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.

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.
