Gaps Under Closed Garage Doors

Have you started noticing a sliver of sunlight peeking under your closed garage door? Or maybe you’ve recently had some uninvited, four-legged guests make their way inside?

A gap between your garage door and the concrete floor is more than just an eyesore—it’s a warning sign. While it usually comes down to three main culprits—a failing garage door, heaved concrete, or settling concrete—at Colorado Concrete Leveling, we find that a shifting floor is most often to blame.

Here is what you need to know about the signs, the problems, and how to fix it.

The Signs: How to Spot the Issue

Aside from a visible gap when the door is fully shut, keep an eye out for these common warning signs:

Sunlight Peeking Through:
Light filtering in along the bottom seal, especially on one side or in the center.

Drafts and Moisture:
Water pooling inside the garage after a heavy Colorado downpour or snowmelt.

Pest Invasions:
Mice, bugs, or spiders suddenly finding an easy entry point into your home.

Uneven Cracks:
Visible cracks spreading across your garage floor, often near the threshold.

The Problems: Why You Shouldn’t Ignore It

Energy Loss:
A broken seal lets cold winter air or scorching summer heat right into your home, driving up utility bills.

Structural Strain:
If the concrete has settled unevenly, it can cause your garage door tracks to misalign, leading to damaged rollers, broken springs, or a burnt-out door opener.

Property Damage:
Water intrusion can ruin stored items, compromise drywall, and even erode the soil underneath your foundation further.

The Solution: Get Expert Advice Today

Don’t just replace the weather stripping. If your concrete is settling, a thicker rubber seal is only a temporary band-aid for a deeper problem.

Contact Colorado Concrete Leveling today for a free on-site evaluation. Our team of local experts will inspect your garage, diagnose the root cause, and give you honest, professional advice on how to level up your home’s safety and curb appeal.

To permanently fix the issue, you need to address the foundation. Replacing an entire garage floor is expensive, disruptive, and often unnecessary.
