No, there should not be a gap between your garage door and the floor. Gaps can make your garage less energy efficient, leading to higher energy bills. They also create an entry point for pests like rodents and insects, as well as rain and melted snow, which can lead to foundation damage or mold issues.

If you have a gap under your garage door, potential causes include an uneven garage floor or worn-out weather stripping. To fix it, you can try several solutions:

• Replace the weather stripping: The seal at the bottom of the door may need to be replaced.

• Adjust the garage door: You may be able to adjust the closing position on your garage door opener to eliminate the gap.

• Inspect the floor: If the concrete floor has shifted or is uneven, it may need to be repaired to create a level surface.

If these solutions do not resolve the issue, it is best to call a garage door repair specialist to inspect the door and floor.

The level of insulation is determined by both the material and the thickness of the door. Some garage door materials (such as wood) have natural insulating capabilities, while other materials (such as metal) do not. No matter the material, two-layer and three-layer garage doors have a higher R-value than single-layer garage doors, as insulation is fitted between the panels. 

Getting a garage door tune-up is worth it. Tune-ups are a form of preventative maintenance that help extend a garage door's lifespan and prevent dangerous issues, like worn springs or misaligned sensors. The cost to get a garage tune-up is far less than letting problems get out of hand and causing costly repairs—or worse—injuries.

A garage ceiling needs a vapor barrier if it’s a heated garage or if you’re installing insulation in the ceiling. Without a vapor barrier, you risk moisture issues and mold growth. If you have an unheated garage and don’t plan on installing insulation that could get wet and harbor mold, the ceiling doesn't need a vapor barrier.
