"From estimate to installation, Brothers that just do Gutters provided outstanding customer service. The project estimate was detailed and clearly explained. All my questions were answered. I received timely updates about the schedule. The installation crew arrived on time. The crew chief walked me through the installation steps to ensure we were on the same page. I highly recommend this company and will will definitely call them for any future gutter projects."

"Joe helped us in our time of need when we had a leak just days before our house was to close. The leak was due to the chimney flashing and he saved the day by repairing it! He was very kind, worked fast, and also did it for a very reasonable price. Definitely recommend!"

"We had a tree growing out of the left corner of our second story gutter. Caio Lanes from Lanes Gutters called and we set up a day and time. He arrived a little after our appointed time but he'd called to say he was going to arrive later. He went right up the ladder and took pictures of the gutter and tree. The 12" to 15" tree was growing in a large amount of damp soil like debris that was clogging the gutter. Clearly we needed to have the entire gutter cleaned. Caio took off the leaf filters, removed the debris, reinstalled the leaf filters and worked his way across the 36 feet length of the front gutter. He worked quickly, had a nice personality and my wife and I are very pleased with the quality of his entire approach. We're going to have him back to clean more sections of our gutters."

"I put in my request through HomeAdvisor and David from D&M contacted me within a few minutes. We set up a time to look at the project for the next day. He gave me a good price and told me he would get the job done the following Tuesday or Wednesday depending on the weather. Wednesday morning as I was drinking my morning coffee I thought to myself, "I wonder if I'll have my gutters today?" Looked out the window and realized they were already up! He had done them Tuesday and the instillation was so well done I hadn't even noticed! We have been through some rain and some snow and they are doing just what I needed them to do. D&M was a pleasure to work with."

"Quality Insulation of Portsmouth did two jobs for me: They added blown in insulation to my attic last fall and installed gutters plus leaf guards this spring. Both jobs were excellently done at a reasonable cost. I would certainly recommend them and will likely use them again in the future."

Gutter Repair and Replacement questions, answered by experts

In most cases, it makes more sense to repair leaking or damaged gutters than it will to replace them. You’ll spend an average of $400 to repair your gutters, while full replacement will cost around $2,000 or more, depending on the gutter material and style and the size of your home. If your gutters are nearing the end of their lifespan—usually around 20 years for aluminum or vinyl gutters or up to 50 years for copper or steel—then it might make sense to replace them, as it could cost you less in the long run.

If you don't want to install gutter guards, the most common and inexpensive alternative is regular gutter cleaning, either annually, biannually, or as soon as they start to fill up. Using a leaf blower attachment can make this process easier. Other products designed to reduce cleanings include gutter screens (made of wire mesh, nylon, or foam), which are typically less expensive than a full gutter guard installation. You can also find guards and inserts designed specifically to protect your downspouts or opt for a whole gutter system like LeafGuard, which integrates the gutter and guard into a single product.

Calcium chloride does not do significant damage to gutters when used properly and in moderate amounts. If you use too much too frequently, it could eventually cause corrosion in your gutters. Rock salt will harm your gutters, though.

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. 

One of the biggest causes of gutter leaks is clogged gutters. If your gutters are full of debris and leaves, water will back up and eventually overflow outside of the gutter. Other common causes of gutter leaks include loosened gutter fasteners, faulty gutter slopes (sagging gutters), separated joints, and cracks or holes.
