Why an Exterior Door Threshold Extension Helped Me

When I first moved into my home, I noticed that the transition between my exterior door and the ground was not as smooth as I would have liked. Rainwater would pool just outside the door, and I often found myself wiping muddy footprints off my floors. After some research, I decided to install a threshold extension, and it has made a world of difference.

One of the most significant benefits I’ve experienced is improved water drainage. The extension creates a barrier that prevents rainwater from seeping underneath the door, which has greatly reduced the risk of water damage and mold in my entryway. I no longer worry about the rainy season ruining my hardwood floors, and I can keep my home looking clean and fresh.

Additionally, the threshold extension has enhanced the overall energy efficiency of my home. By sealing the gap between the door and the ground, it minimizes drafts, keeping the warm air in during winter and the cool air in during summer. This has not only made my home more comfortable but has also led to lower energy bills. I feel like I’m not just investing in my home’s aesthetics but also in its energy performance.

Lastly, the extension has improved accessibility. As someone who occasionally has guests with mobility
