How to install?

  • STEP 1

    Remove Old Vent

    Carefully remove your existing foundation vent. Clean away any remaining debris, old caulk, or mounting materials from the opening.

  • STEP 2

    Prepare the Surface

    Ensure the mounting surface is clean, dry, and level. For masonry foundations, verify the surface is smooth enough for proper adhesive contact or mark anchor hole locations.

  • STEP 3

    Surface Mount the Frame

    Secure the vent using either premium construction adhesive for a permanent bond or masonry anchors for maximum hold.

  • STEP 4

    Install the Flood Activated Insert

    Snap in your chosen insert configuration vented, solid, or insulated.

FAQs

Yes, all FloodGuard flood vents are ICC-ES certified and meet FEMA Technical Bulletin 1 requirements. They're engineered to automatically equalize hydrostatic pressure during flooding, which satisfies NFIP (National Flood Insurance Program) requirements. This certification ensures your flood insurance remains valid and can help lower premiums in flood-prone areas.

Engineered flood vents are permanent ICC-rated openings designed to allow floodwater to flow through your foundation walls, preventing structural damage from hydrostatic pressure. Breakaway vents are designed to fail and detach during flooding - allowing the widest possible debris opening to clear your crawl space of moisture. Our vents are the superior solution and they can be reused after flood events.

Each FloodGuard vent provides 305 square feet of flood zone coverage. Measure the square footage of your crawl space and divide by 305 to determine the minimum number of vents needed. You'll need at least one vent per 150 square feet of crawl space, and vents must be installed on at least two different exterior walls. Our team can help you calculate your specific requirements.

FloodGuard Vents work for both new construction and retrofit installations in existing foundations. For existing foundations, you'll need to repurpose existing foundation vents or core drill openings to the appropriate size. Our vents are designed for straightforward surface-mount installation with basic tools, though we recommend working with a qualified contractor for cutting into existing foundation walls.

Yes, our insulated models feature foam-core construction that provides thermal protection for your crawl space while still meeting all flood vent requirements. All our vents include integrated louvers and screens that prevent pest entry while allowing proper ventilation. They're designed to perform year-round, not just during flood events.
