Today we talk about a common issue of Why Is There a Gap Under My Garage Door and How Can It Be Fixed? A gap under your garage door can allow water, dirt, pests, and outside air into your garage. While a small opening may seem harmless, it can indicate worn weather stripping, an uneven floor, or a door alignment problem. At Alliance Overhead Door, We recommend identifying the cause before deciding on the right solution.
What Causes a Gap Under a Garage Door?
A worn bottom seal is one of the most common causes. This flexible strip runs along the bottom of your door and creates a barrier against the garage floor. Over time, weather exposure and daily operation can cause it to crack, flatten, or pull away.
An uneven garage floor can also create gaps, especially when concrete settles or slopes. Additionally, worn rollers, damaged tracks, or improper door alignment can prevent your garage door from closing evenly.
If you are considering Garage Door Installation in Simi Valley CA, checking the floor and garage opening beforehand can help ensure a proper fit.
Can a New Bottom Seal Fix the Gap?
If your garage door operates correctly but the weather stripping is worn, replacing the bottom seal may solve the problem. Different garage doors require different seal styles, so choosing the proper type is important.
However, weather stripping cannot correct every issue. If the floor is significantly uneven, a larger threshold seal may be needed. Likewise, mechanical problems should be corrected rather than hidden with additional weather stripping.
Does Your Garage Door Need an Adjustment?
Sometimes the gap is caused by a door that no longer closes evenly. You may notice one side touching the floor while daylight remains visible beneath the other side.
Professional Garage Door Repair in Simi Valley CA can identify whether tracks, rollers, cables, or other components are affecting the door. If incorrect spring tension is preventing proper balance, Garage Door Spring Repair may also be required.
Why Should You Fix a Garage Door Gap?
Closing the gap helps protect your garage from rain, leaves, dust, insects, and rodents. Additionally, proper sealing can reduce drafts and limit hot or cold outside air entering your garage.
Fixing the underlying problem may also reduce unnecessary strain on the door. For example, an improperly balanced or misaligned system can place additional stress on other moving components.
Find the Right Solution for Your Garage Door
Before replacing parts, determine why the gap developed. A professional inspection can evaluate your bottom seal, floor contact, tracks, alignment, and operating hardware.
At Alliance Overhead Door, We can identify the source and recommend an appropriate solution. Ultimately, correcting the actual cause helps your garage door close properly while improving protection, appearance, and dependable everyday operation.
