Can you replace only one section of a gutter?

Accepted Answer

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.

Question 2

What is the best sealant for gutters?

Accepted Answer

•

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.

Question 3

​​Do buried downspouts freeze?

Accepted Answer

•

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.

Question 4

Is it better to repair or replace leaking or damaged gutters?

Accepted Answer

•

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.

Question 5

Do you have to caulk vinyl gutters?

Accepted Answer

•

Yes, caulking or sealing your vinyl gutters is a good way to help prevent gutter leaks. When you’re installing gutters, it’s important to overlap the sections to help avoid issues like leaks or drips, but they can still happen. In this case, adding caulk can help. Make sure to use a caulk designed for multiple surfaces, like a silicone-based caulk. You can also purchase a gutter sealant as well, which is specifically designed for this purpose.
