DoorDam
Q: What is DoorDam?
A: DoorDam is the first effective “off-the-shelf” flood barrier product designed specifically for the millions of homeowners and small businesses in flood-plain areas across the U.S. DoorDam is a convenient, cost-efficient replacement for sandbags and plywood, which have been the primary flood protection tools for homes and small businesses until now. DoorDam flood gates are re-usable, reliable and easy to use.
Q: How is DoorDam constructed?
A: Our patented design and heavy-duty construction will keep the water out, yet is lightweight and easily installed by one person.
• Lightweight rugged frame made of aircraft-grade aluminum
* DoorDam 3600 is made of welded steel beams
• Stainless steel scissor jack is strong and rust resistant
• Industrial-quality, waterproof neoprene pouch keeps
the water out
• A tough, coated aluminum debris guard protects against
floating
By turning the handle at DoorDam’s top edge, you expand its width to press the seals against the vertical surfaces at either side of a doorway or similar opening which creates the watertight seal. Jamb compression clips provide downward sealing force.
Q: How Does DoorDam Work?
A: DoorDam is designed to fit inside, across an opening and then securely expand to keep out floodwaters. Once properly installed in an otherwise watertight building, DoorDam will provide a watertight barrier to help keep floodwaters out. A variety of brackets are available to install DoorDam properly depending on the type of opening you have to protect. Once the brackets are installed, DoorDam slips down between them, and with the turn of a handle a powerful scissor jack is engaged and the DoorDam then expands to fit the opening.
Q: Where can I use DoorDam?
A: DoorDam is flood protection for well-maintained buildings that are watertight except for their doorways or a similar opening. Needless to say, if the walls of a structure are not watertight, DoorDams alone, will not provide adequate protection. The requirement for a watertight structure is explained in all DoorDam product literature and is part of the conditions agreed to in the DoorDam purchase process.
Q: What type of structure is appropriate for DoorDam?
A: DoorDam is suitable for structures that are constructed of concrete, brick, sealed stone or other watertight materials in good watertight condition. These structures must not have basement windows or sunken/slanted outdoor cellar doorways. DoorDam can work in wooden structures if they are fully encircled by a watertight concrete foundation that rises at least 18” above the lowest doorway footfall for DoorDam 1800, 26" for DoorDam 2600, and 36” high for DoorDam 3600. Again, such structures should not have basement windows or sunken/slanted outdoor cellar doorways.
Q: Where can't I use DoorDam?
A: DoorDam is not suitable for non-watertight structures such as wood frame houses with foundations lower than 18” above the lowest doorway footfall. DoorDam is also not appropriate for any structures with basement windows or with sunken/slanted outside cellar doorways.
Q: How much water will DoorDam keep out of my home or office?
A: DoorDam 1800™: 18-inches tall and is designed for minor to moderate flash flooding, storm drain overflow, etc.
DoorDam 2600™: 26-inches high and is designed for heavy flooding and hurricane protection.
DoorDam 3600™: 36-inches high and is our industrial model designed for severe flooding and hurricanes and heavy-duty protection
- If you think the height of floodwaters could exceed 16-inches, the DoorDam 2600 is the right model. If water could exceed 24-inches and you need industrial
protection the DoorDam 3600 is correct.
Q: Can DoorDam be used more than once?
A: That’s one of the great features of DoorDam. Unlike sandbags and plywood, DoorDam can effectively protect you from floodwaters again and again. With proper care and maintenance, your DoorDam will last for years.
Q: Is DoorDam waterproof?
A: DoorDam is watertight, but not necessarily waterproof. You may experience some leakage around the edges, depending on the quality of the seal you are able to create. If the vertical surfaces beside your door opening are too irregular for a flush fit or if there is not an adequate backstop to hold back the force of the water, you WILL need to install brackets (sold separately except for J-Brace) to ensure proper sealing for DoorDam. They should be installed on each side of the doorway, either inside the doorway itself or on the surfaces just outside of it. DoorDam User 1800 & 2600 Manual : DoorDam 3600 User Manual
Q: My opening is greater than 50” wide -- what can I do?
A: DoorDams can be used individually or in multiple units by connecting them end to end with Mullions. When using multiple DoorDams, they are joined by mullions for anchoring (sold separately). Anything larger than the standard sizes, can be customized to your needs. Just call 1-866-DOORDAM (366-7326).
Q: How much does DoorDam weigh?
A: DoorDams are available in 7 18-inch and 26-inch sizes that protect openings from 28" to 50" wide and 8 36-inch sizes that protect openings from 25” to 50” wide. The weights of each run from 26 pounds to a maximum of 70 pounds, depending on the amount of protection you need. As an example, a DoorDam 2600 that fits in a 36” wide opening weighs about 43 pounds, which is almost equal to one sandbag. However, a single DoorDam that size can do the job of 50 sandbags (source: Army Corps of Engineers). A DoorDam 3600 protecting three linear feet replaces 102 sandbags!
Q: How much does DoorDam cost?
A: DoorDam retail prices range from $398 and $715 depending on the model chosen. Online or other discounts may apply, so be sure to review the specific model you need for current pricing.
Q: Where can I buy DoorDam?
A: DoorDam can be purchased by calling us at 1-866-366-7326, or from an authorized dealer. Information you need prior to ordering DoorDam for flood protection.

A: We use standard UPS shipping, but rush delivery is available for a fee.
Q: Can I return the DoorDam if I don’t like it?
