"I had Sam inspect my gutter and siding for damage after the recent hail storm. Sam came out took pictures and helped me with the insurance process. I got a new gutter and siding all paid for by my insurance company and I did not have to do anything except decide on what colors I wanted. I can honestly see why now that I have done business with them. I hope I never have to replace my siding and repair my gutter again but if I do I will be calling All Complete Construction. Thanks"

Gutter Repair and Replacement questions, answered by experts

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.

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. 

Frequently, when water flows over gutters, it indicates a potential clog, necessitating cleaning. For instance, if a twig becomes lodged in the downspout, it can lead to a traffic jam, causing more leaves and sticks to accumulate. Another potential issue is an incorrect pitch, as gutters should channel water toward the downspout. If you observe water overflowing the end cap or leaking through it, it suggests that your gutters are improperly tilted.

Yes, it’s possible to replace only one section of a gutter, and it’s a common repair. Often, a tree limb will damage a gutter on one side of the house, or constant weather will cause early corrosion. Gutters are often joined together with couplings that are easy to remove and swap out. For this reason, some homeowners will purchase extra gutters when they install them to have spare sections to use for replacement later.

Absolutely—and lots of it. Overflowing water from your gutters can damage your siding and your roof. All of the moisture getting into the cracks and crevices of your home can lead to mold or mildew problems down the line. In addition, when water pools around your home, it needs a place to go—and sometimes it ends up inside the house, creating a very unwanted flood.
