"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."

"I liked the way every detail we had discussed was itemized in the contract. Henry, the owner, was always polite, answered my questions and assured me that my concerns would be met. They showed up at 7:30 am, like they said they would, and finished the roofing in one day, doing an excellent cleanup job,too. The next day they put up screened gutters and downspouts. I decided to order it with screening because the screening cost will be recouped in 2 or 3 years by not hiring someone to clean the gutters. I interviewed five people and choose this company because they had a 5 star rating, their price was a great value for what they did and I interviewed the owner, Henry, not a salesperson, and he seemed very sincere in listening to and addressing my concerns."

"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."

"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."

"I had a great experience with Fairfield Gutter and Exteriors! From start to finish, they were professional, efficient, and very thorough. They came out to assess what needed to be done and took pictures so they could clearly explain everything that needed attention. They walked me through the entire process and explained in detail what needed to be done, which I really appreciated. Once they started the repair, they completed everything in just about two and a half hours! The work was done efficiently and professionally, and they did a great job. I was also very impressed with how affordable the service was. I highly recommend Fairfield Gutter and Exteriors to anyone looking for reliable, professional, efficient, and reasonably priced gutter or roofing repair services. Excellent service from beginning to end! Maria R."

Gutter Repair and Replacement FAQs, answered by experts

When you need to repair your galvanized gutters from leaks and caulk isn’t doing the job, you can solder your gutters with a roofer’s soldering iron. First, you’ll need to clean your gutters thoroughly with a wire brush and remove rust and oxidized paint. Next, you’ll make weld points on the gutter and solder over the connection until it’s completely smooth. You can also hire a roofing company near you to tackle this project.

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.

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. 

While minimal drippage may not be problematic, gutters that are constantly leaking or overflowing indicate damage or improper installation. A rain chain gutter or other ornamental feature may produce more dripping than usual. Likewise, rain dispersal systems may also cause water to sprinkle to the ground. However, if you notice pools of water or flooding around your property, then it’s a good idea to have your gutter system inspected.

The most common problem with gutters is clogging from debris like leaves, blossoms, and seeds from surrounding trees. This debris can block downspouts, leading to improper drainage and water overflow.

Other common issues include:

  • Leaks and holes, which can often be repaired with gutter sealant or caulk.

  • Rust, sagging, or detachment from the roofline.

  • Damage from strong storms.

  • Improperly pitched gutters that don't drain correctly.

Regular cleaning in the spring and fall is the best way to prevent most of these problems. You may need to clean them more often during periods of heavy leaf fall.
