Can a Misaligned Garage Door Let In Insects
and Moisture?
Yes — a misaligned garage door can create small gaps around the bottom or sides that allow insects, moisture, sand, and humid air to enter your garage. Even tiny misalignment issues can let in ants, roaches, spiders, and water during rain or storm season.
Why Alignment Matters for Florida Garages
In Florida climates — with humidity, rain, and frequent storms — keeping the garage sealed tight is essential.
A properly aligned door sits flush against the floor and frame, creating a secure seal.
When alignment is off, you may notice:
- Light peeking in around the door edges
- A small gap along the floor
- Wind, sand, or water blowing inside
- Humidity rising inside the garage
- Insects sneaking through corners or track gaps
A flush seal protects your home’s interior, walls, stored items, and keeps pests outside where they belong.
Common Causes of Garage Door Misalignment
- Worn or damaged bottom rubber seal
- Tracks out of adjustment
- Settling concrete or shifting floors
- Door hit by a vehicle or bumped by equipment
- Broken or weakened springs affecting balance
- Florida storm pressure and humidity shifting components
Even a slight tilt or uneven drop can break the weather barrier.
Signs Your Door Might Be Misaligned
- You see daylight around the edges
- The bottom rubber doesn’t sit flat on the floor
- Door shakes or rubs while opening
- Water trails or sand under the door after rain
- Bugs appear more often in corners or near the seal
- One side touches the ground before the other
If you see any of these, it’s time to check alignment before bigger issues develop.
Can a small gap really let in pests?
Yes. Ants, roaches, spiders, and lizards only need a tiny opening to enter.
Does misalignment cause water leaks?
It can — especially during heavy rain or wind-driven storms.
Will humidity enter through a misaligned door?
Absolutely. Warm, moist air flows through even small gaps.
Should I fix misalignment myself?
Garage door components are under tension, so it's safer to have a trained technician adjust alignment and seals.
When to Call a Garage Door Technician
Contact a professional if:
- You can see light or feel air near the seal
- Your door won’t sit perfectly level on the floor
- Water or insects are entering the garage
- The door is noisy or rubbing the tracks
- You suspect spring or track issues
Correct alignment helps keep pests, weather, humidity, and damage away — especially in Florida environments.
