How to Run a Conduit Through an Exterior Wall to Avoid Water Leaks

Publish date: 2024-02-28

Introduction

Hidden water leaks caused by improper cable and phone line penetrations through the siding can cause rot and mold.

As a homeowner, you willingly go to great lengths to prevent leaks from causing water damage to your home. Think about the time spent cleaning gutters, making sure windows and doors are properly sealed, checking the chimney cap and the flashing, inspecting pipes, and on and on.

It’s all worth the effort because few things can be as ruinous to a home as unseen water leaks. But there’s one potential weak spot that may have escaped your attention: that spot in your exterior of your home where cable comes into it. Whether it’s a phone line, cable television or home internet, if the cable is improperly installed, it can lead to water damage.

Fortunately, there’s a simple fix that you can do yourself to prevent water from running across the cable and into your home where it can lead to mold or other water damage.

For this helpful hack to work, it assumes that the cable has been installed properly. Ideally, the cable should run upward and then into the home.

As a reminder, cable should never run downward and directly into your house. Rainwater will cling to the cable and follow it right into your home.

If your cable was installed incorrectly, contact your service provider and voice your concerns. They should be willing to fix the problem, but if the provider refuses to do anything about it, see if you can reroute the cable in order to gain a couple of feet.
