What Is the Bottom Gap?
The bottom gap refers to the space between the bottom of your garage door and the ground. Ideally, this gap should be minimal to ensure a tight seal. Over time, factors such as settling foundations, wear and tear, or improper installation can cause this gap to widen.
How It Works
The bottom gap is typically sealed with a weatherstripping material that compresses when the door closes. This seal is essential for:
- Preventing air leaks.
- Blocking out pests.
- Keeping moisture at bay.
Main Purpose
The main purpose of adjusting the bottom gap is to ensure that your garage door operates efficiently while providing protection against external elements. A well-adjusted door not only enhances security but also prolongs the lifespan of your garage door system.
Common Reasons for Adjusting Garage Door Bottom Gap
Understanding the common reasons for adjusting the bottom gap of your garage door can help you identify when it’s time to take action. Here are some prevalent situations and problems that make this topic relevant:
1. Settling Foundation
Over time, the foundation of your home may settle, causing the garage door to become misaligned. This can create a larger gap at the bottom, compromising the seal.
2. Wear and Tear
Frequent use of the garage door can lead to wear on the hinges, springs, and tracks, which may affect how the door closes and create gaps.
3. Weather Changes
Extreme weather conditions, such as heavy rain or snow, can cause the ground to shift or settle, impacting the alignment of your garage door.
4. Improper Installation
If your garage door was not installed correctly, it may not sit flush against the ground, leading to an uneven gap.
5. Damaged Weatherstripping
Old or damaged weatherstripping can lose its effectiveness, allowing air, water, and pests to enter through the bottom gap.
