DIY Flood Barrier Tips to Prepare for Flooding During Storm Season

Simple Ways to Help Protect Your Home

When storm season arrives, heavy rain, rising tides, and overflowing drains can quickly turn into destructive floods. For homeowners, the difference between minor water intrusion and costly damage often comes down to preparation. The good news? You don’t need an expensive contractor or bulky equipment to protect your home. With the right DIY flood barriers and sealing methods, you can create an effective defense line against floodwaters.

Understanding Flood Risks During Storm Season

Storm season brings unpredictable weather patterns, including tropical storms, hurricanes, and severe thunderstorms. Flooding can occur when storm surges push water inland, when drainage systems are overwhelmed, or when homes sit on low-lying ground. Even a few inches of water can cause thousands of dollars in repairs, ruin flooring, and destroy personal belongings. Taking preventive action now is one of the best ways to minimize risk.

Essential DIY Flood Barrier Options

1. Sandbags and Alternatives

Sandbags are one of the oldest flood defense tools. When stacked correctly, they form a barrier that slows down or redirects water. However, they’re heavy to fill and move, and disposal after a flood can be messy.

Today, there are lightweight alternatives, including water-activated bags that expand when wet. These are easier to store, deploy, and clean up while offering similar levels of protection.

2. Plastic Sheeting and Plywood Shields

Covering doorways, windows, and garage entrances with heavy-duty plastic or plywood can provide short-term protection from rising water. When secured properly, these shields help block out water and debris carried by floodwaters. Adding bracing to garage doors and crawl space openings also helps reinforce areas that are especially vulnerable.

3. FloodTape® for Sealing Leaks and Gaps

Traditional barriers only go so far if water seeps in through cracks and seams. That’s where FloodTape® stands out. This heavy-duty doublesided tape creates a watertight seal that can be applied to doors, windows, vents and any clearances or gaps prone to water intrusion. Unlike standard duct tape or packing tape, FloodTape® is engineered to resist water intrusion without leaving any residue or damage to the paint when removed! FloodTape® is an essential part of any storm preparation kit. It applies quickly, adheres strongly, and helps prevent small leaks from turning into big problems.

4. DIY Water Diversion Techniques

In emergencies, homeowners often get creative with what they have on hand. Buckets, boards, or even rolled-up tarps can help redirect water away from entry points. Landscaping sand or gravel can also be shaped into makeshift channels. While these solutions may not hold up for long periods, they can buy you valuable time during heavy rain.

Step-by-Step Tips for Installing DIY Flood Barriers

1. Clear debris from around doors, drains, and low-level windows.

2. Lay out your barrier materials in advance so you’re not rushing during a storm.

3. Stack or layer barriers tightly to minimize gaps.

4. Apply FloodTape® to seal around edges, seams, and cracks where water could sneak in.

5. Reinforce large openings like garage doors with plywood or bracing.

6. Test your setup with a garden hose or bucket of water before the storm arrives.

Mistakes to Avoid

Flooding during storm season can’t always be avoided, but smart preparation can make all the difference. By combining proven DIY flood barriers with modern solutions like FloodTape®, homeowners can significantly reduce the risk of water damage.

Make sure to prepare well in advance. There’s nothing worse than waiting until the last minute when supplies are sold out and storms are imminent. Providing ample time for setup helps ensure that smaller entry points, such as vents and crawl spaces, are not overlooked. Use only specially designed FloodTape® to seal sensitive areas. Standard tape or thin plastic won’t hold up to water pressure. Of course, don’t rely on DIY barriers as long-term floodproofing measures.

Remember, flood barriers are only part of the equation. Homeowners should also move valuables and electronics to higher levels, inspect and maintain sump pumps and backup systems, and keep an emergency kit with flashlights, batteries, food, and water.

Make FloodTape® Part of Your Flood Preparation

Taking the time to prepare now ensures you’re ready when the next storm rolls in. Stay drive, stay safe, and stay one step ahead with FloodTape®.
