"Ray was very experienced and helpful and eager to help me with my gutter drainage issues. He didnโ€™t just install brand new guttersโ€”he examined the entire exterior of my house and made recommendations for downspout placement that would drain most of the rainwater away from my house. He made other non-gutter suggestions to help with my drainage issues as well. I had four contractors come to my house for this work and I gave them all the same direction. He was the only one who actually addressed my questions. I would use him again and recommend him highly to others looking for a consultative approach to their gutter project."

"I had a great experience from initial phone call inquiring about gutter repairs and roof repairs on my home. After contacting a few companies for estimates. I decided the customer care, warranty, and pricing was best with Home Genius. I had my roof and gutters replaced with gutter guards, the crew was efficient, neat, but most importantly everything looks great! Thank you to Alex, Andrew, Becca, and Taylor they were all knowledgeable and answered my random questions almost immediately."

"They were prompt, quick, neat and when the job was finished, the foreman went around the house with me to ensure all
was done to my satisfaction. They also fixed the connection between the drain and the new gutter. ย The price is with a coupon, but I don't recall the amount.

Gutter Repair and Replacement FAQs, answered by experts

The cost to repair copper gutters typically ranges from $200 to $1,500. The final price is determined by the severity of the damage, current material costs, labor rates, and whether any additional reinforcements are needed for the repair.

The trick to getting gleaming gutters can vary based on the material of your gutters. Aluminum gutters can often be restored to pristine condition by using a cloth to scrub them with a solution consisting of 1 cup of vinegar and 1 cup of water. Vinyl gutters can be whitened using dish soap and water. For deeply stained vinyl gutters, adding bleach with water and dish soap may help to remove black streaks. Many retailers sell premixed gutter sprays. Applying cleaning solutions to dry gutters before rinsing can help cleaners attach to dirt and grime for easier removal.

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.

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

The best way to seal gutters is with a combination of waterproof roofing cement and silicone gutter sealant. This powerful duo works to prevent water from escaping through holes and cracks while allowing for breathability. While you can use polyurethane sealants, silicone sealants tend to be more flexible when it comes to climate. Silicone is UV-resistant and bonds well to many surfaces. However, polyurethane sealant bonds better with wood.
