Flood-Proofing Your Garage Door

For many, a garage is a secure storage location, a place to work or a home for a vehicle. Your garage door should be able to stand up to inclement weather, but periodically verifying that your installation is in solid condition is still a wise move.

It’s always better to take a proactive approach to flood-proofing a garage. This guide will give you tips and steps on how to keep your attached or detached garage dry.

The Reality of Flooded Garages

All it takes is a small imperfection in weatherstripping or a gap between the bottom of a garage door and the ground to let water seep in. Similar to the rest of your home, a garage is enclosed, making it difficult to dry surfaces after water enters. A flooded garage is a surprise no one wants to discover, as mold growth can begin shortly after a storm passes through.

The reality of a flooded garage is you can be set back in more than one way. First, the vehicles, tools or personal belongings you keep in the enclosed space are at risk of damage, and second, you could end up paying thousands of dollars in structural repairs. It’s worth taking garage door flood prevention seriously to sidestep a major headache and financial burden down the road.

Why Garage Flooding Occurs

Garage door flooding can happen due to several events, some of which are more preventable than others. The most common reasons for garage door flooding are below:

  • Weather-related instances: Rainstorms and wind put stress on garage doors. Bent panels, compromised seals, missing hardware and crooked tracks allow water to enter easily during these events. Contacting a professional for repairs before a storm strikes is your best move to prevent flooding.
  • Sewage backups: Intense rainfall, plumbing clogs and cracked connections may result in water rising from drainage outlets. Monitor your property for standing water that sits close to your garage door entrance.
  • Faulty home water pipes: You could have plumbing connections freeze and crack. This results in gallons of water leaving the system and pouring into your garage from above or through nearby walls.

How Can I Stop My Garage From Flooding?

Determining how to keep water outside your garage door may look different based on the age of your overhead door installation and where on your property the garage door sits.

Garages can flood from multiple angles — via the door, up through the ground, or through walls and ceilings. Prepare for unexpected events by walking around your property to see where you can make changes from outside your storage space.

Preventive Measures for Attached and Detached Garages

An excellent way to reduce the likelihood of your garage flooding is to put gutters around the perimeter. Gutters allow you to guide water away from your home’s exterior and toward drains or the street. You might also explore flood prevention measures such as:

  • Waterproof veneers: Coatings for wood are useful in keeping moisture out of garages.
  • Foundation repairs: Seal up cracking concrete below your residential space to ensure water stays out.
  • Landscaping: Cleaning up yard clippings and leaf piles around the garage stops hidden puddles from lingering and growing larger.
  • Stack sandbags: Bags of sand make outstanding barricades. Build a dam to block water or direct it toward an exit path.
  • Install traditional drains: A professional may put additional drains in and around the garage to help water leave quickly.
  • Create French drains: A French drain is a trench filled with gravel that redirects water. Placing one near your garage can help prevent pooling and flooding.
  • Storm shields: If your concrete surface is unlevel, consider using a rubber barricade at the bottom of the garage door to prevent water entry.
  • Lawn maintenance: Check your property for moving water that flows toward the garage — you may be dealing with poor grading.

How Do You Flood-Proof a Garage Door Installation?

Your garage door is in the line of fire during a severe storm or emergency. You likely open and close your overhead door dozens of times a week, so it’s a good idea to use your eyes and ears to detect issues with an assembly before the forecast takes a turn. Note that you should only have an experienced professional perform garage door maintenance and repairs, as the springs are under high tension and require training to work on safely.

It’s important to realize that it’s impossible to have a 100% waterproof garage door — but there are methods that can help in stopping water from reaching your storage space.

Before you start the process, request an inspection to have a trained technician come to your residential space and identify areas requiring attention. Keep these recommendations in mind to flood-proof a garage door.

1. Replace Garage Door Weatherstripping

Weatherstripping lines the bottom and sides of your garage door. It’s best to visually inspect this element between seasons to ensure it is still doing its job. From noticeable gaps in weatherstripping to sections that appear dry or discolored, issues with this material may allow water to enter your garage. The right garage door team can apply new weatherstripping for your peace of mind.

2. Change the Door’s Cables and Springs

An uneven garage door does little in the fight against flooding. You’ve probably noticed all of the cables and springs that make up your overhead door assembly — these components hold an incredible amount of tension and should be assessed periodically to gauge their reliability. Schedule cable and spring repair services to get your overhead door to sit even with the ground and keep water out.

3. Update or Replace the Hinges

Your garage door features hinges between moving parts. The panel surfaces require these hinges so the overhead assembly can move from the open and closed positions freely.

Hinges on panels will eventually wear out with time and use, leaving weak spots across surfaces where water can enter. Having an expert replace worn hinges is effective for protecting your space and increasing the structural integrity of your installation.

4. Replace Your Overhead Door

There comes a time when it’s more cost-effective to select a garage door replacement than repair an old model.
