"I spoke with Joe, from Gutter Brothers, about checking out my gutters for alignment and cleaning them. His team came when at their scheduled time and performed the work that I had asked. The very next day we had a heavy rain for several hours and my gutters go the job done."

"Riza was very professional and very nice to work with. He and his workers did a great job repairing and replacing exterior window trim and minor deck repairs. He also built a platform to raise my fridge which was an additional request. They even repaired a screen door and added an additional support. Great work ethic, responsive, and work done well and finished fast. I recommend and would hire again."

"We were looking to have gutter and downspout work on our home, but economic times being what they are, we wanted to get a few estimates to try and stay within our budget. Unfortunately the amount quoted from this company was somewhat more than we could pay without financing it. That said, the rep who came out, I believe his name is Edgar, did a great job outlining what the procedure would entail. He was very professional and took the time to answer all our questions."

"These guys are competitively priced and highly professional. Thorough job power washing our 3 story British Colonial Home (circa 1754) including a good deal of intricate molding around the windows and western red cedar roof. Diagnosed necessary repairs to our copper gutter system and downspouts. Quickly provided a detailed quote on that overhaul work. They are on my short list of home service providers going forward. These guys are a diamond in the rough."

Gutter Repair and Replacement FAQs, answered by experts

There are a handful of things you can look for to determine if you need to pay for gutter repairs, including the following:

  • Water leaking from the underside of your gutters during rainfall

  • Visible gaps between your gutters and your roof

  • Frequent issues with gutters overflowing or holding standing water

  • Gutters that sag or pull away from the house

  • Water damage to soffits, fascia boards, or other building materials

  • Mold growth on your exterior walls

  • Soil erosion underneath your roof overhang

  • Foundation leaks or inward bowing of foundation walls

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.

Gutters should not drip at the seams. This problem could indicate that water is collecting in the gutters instead of moving to the downspouts. You could have leaves or other debris blocking the flow of water at the seams. Try cleaning the gutters, adjusting the slope, and sealing any holes or cracks in the material to fix this problem.

You may have a clogged gutter. Downspouts can also clog if your gutter collects too much debris. Hire a professional gutter cleaner, and if you still have problems, install a gutter guard (which prevents debris from entering your gutter system) and a downspout extension (which helps drain water further away from your foundation, so it doesn't pool near your house). Follow these tips to keep your gutter downspouts clean.

Unless you've chosen to install underground downspouts, your gutter downspouts shouldn't touch the ground. If they come into contact with the soil or pavement next to your home, rainwater can back up into them during a storm, preventing them from doing their job effectively. Instead, aim to have your downspouts end about 12 inches from the ground.
