Frequently Asked Questions

How does flowstop prevent flooding damages?

Our inflatable devices are custom-made to fit your door’s frame and create a high-pressure, sealed barrier in any framed opening, preventing water from entering.

Can I set up a Flowstop against a window?
Yes. The pressure that holds the flowstop in place is against the frame, the side of the opening, not the door or window. Flowstop won’t put any pressure or resistance or inflict any damage to your door or window.
Does flowstop resist strong wind?
Yes, our technology is designed to resist pulling and pushing forces.
Is flowstop resistant against debris?
Yes! We tested our flowstop against heavy logs, bricks, and scissors. Our double PVC panels are incredibly resistant.
Can I use Flowstop if my frame is uneven?
Yes, Flowstop is an inflatable device; therefore, the shape of the devices will adapt to the unperfect environment.
Can I use Flowstop on a slope?
Yes, Flowstop will hold a strong seal on a slope as well.
Where can I see flowstop in person?
We are offering a demo program. Contact us to get your demo device sent to your house.
When do I set up my Flowstops?
Your Flowstop devices can be inflated minutes or months before a risk of flooding is announced. We designed our high-quality valves to keep the pressure up to 2 months.
Temperature
Flowstops are inflated at 13.5 PSI pressure. At such pressure, even in extreme temperature differences, the pressure is such that there is no alteration of the shape or resistance. We tested Flowstops at 167f without any problem.
What size do I order?
Measure the size of the opening you want to protect (not the size of the door/window) and order a flow stop of that width. Please visit our tutorial for more information.
What size do you have?
Flowstops are custom-made to fit your opening. We can custom-make any size or shape. Our standards are rectangular shapes with 31.5″ in height, 6″ – 7.5″ in depth, and 40″- 177″ in width. We can also custom-make round or square devices.
Do I need to purchase tools or other equipment to use my Flowstop?
No, there is no additional cost or need for any installation tool. We include a pump to inflate your Flowstop with your order. You only need a measuring tape to measure the width of your openings before ordering to ensure we create the perfect flowstop for your doors and windows.
How long does it take to receive my devices?
Standard sizes that we carry in stock ship within 3 days; depending on the size you need, custom sizes can take up to 3 weeks to produce.
Can I re-use my flowstops?
Yes! Flowstop guarantees over a hundred uses.

    I equipped myself with an inflatable Flowstop model because my house has already been flooded during rising water levels. I have not yet been able to test its effectiveness myself, but the product is very easy to set up. Moreover, the company was very attentive to the problems specific to my situation, and they enabled me to equip myself as best as possible thanks to their expertise and advice. They were also very accommodating. Thanks to them.
  • Gérard Bastian

    The company is very responsive, from the initial contact to the delivery of the product, providing serious and, as mentioned, responsive support. The product is of high quality and stands out for its simplicity and speed of implementation. Highly recommended!

    Following our initial contact, the team came out for a demonstration; the product is super easy to implement and very convenient (lightweight, doesn’t take up much space). Fingers crossed that we won’t have to use it too often…

    Positive aspects: Professionalism, Quality, Responsiveness. The concept is truly innovative. Custom-made, space-saving, easy and quick to install. I also really appreciated the company’s responsiveness to the questions I had.
  • Géraldine Perrin Cabard

    Absolutely brilliant! Custom-made, easy to install (even my teenager can do it) that protects without detracting from the aesthetics and structure of the house. I really recommend it! Insurances should offer them, they would benefit!
  • Christian Querion

    I contacted this company in July to protect a basement with a 2.40m garage door from flooding. The device was received in August, and the initial tests with sustained watering were not conclusive. There was a slight defect that prevented a perfect seal. So, I got back in touch with the company, supported by photos, and they restarted the production of a new Flowstop. This morning, Olivier Guillou (the company’s manager) came to install and test the new device. The tests were…
