Floodshield Barrier Fit & Installation

How easy is it to fit a Floodshield?

Very easy. Floodshield’s were designed to be fitted quickly and without tools, even in an emergency. Simply wind the clips to the right length, press the barrier into place, and it's ready. Full installation instructions are available online so head over to How it works page to find out more.

Do I need any tools or permanent attachments?

No tools, no screws, no ugly fixings. Floodshield clips securely to your door frame with its unique compression system. You can store it away and deploy it in under a minute. Great for rented homes or listed buildings too. Check out our How it works page to find out more.

What size door will a Floodshield protect?

Floodshield fits most UK single residential doors, from 760mm to 960mm wide. If your door is slightly outside this range, we may still be able to help; just send us your measurements and we’ll advise. For larger openings like patio or garage doors, we recommend FloodSax.

My doorframe is very deep, will your clips reach the frame?

Each Floodshield comes with standard 50mm bolts. If your frame is unusually deep, we can supply longer bolts on request, just let us know at checkout or contact us.

My doorframe is narrower than the 35mm needed, what can I do?

Affixing a wooden batten each side of the door frame will increase the width of the outside surface to a above the required 1 ½ inches (35mm). This will allow the barrier to seal and clip to the frame correctly. Once the wooden batten is painted it becomes part of your door frame. Go to our wooden door frames help section for a diagram example. Visit our How to Install page for full details on installation.

Standard vs Closed Floodshield: how do I know?

Use a Closed Floodshield only if your door has a continuous solid threshold along the bottom. If the base of the doorframe is not sealed, go for the Standard model. For more details please visit our How to Install page.

Will it fit around the plastic trim on my UPVC door?

UPVC door frames are approx. 75mm wide, which allows the barrier to overlap at least 35mm each side of the door frame. This width means that there should be ample space to fit the barrier whilst avoiding the plastic trim. Go to our UPVC door frames help section for a diagram example of this. Visit our How to Install page for full details on installation.

Do Floodshields work with outward opening doors?

No, the barrier is only compatible with inward-opening doors. For outward-opening doors, we recommend FloodSax.

Can I stack multiple Floodshield on top of each other to get a higher barrier?

Unfortunately not. The barriers are not built to seal water tight this way - once water levels reach this height there are likely to be many more entrance points for the water, for example windows, ventilation. Check out our Full Home Protection range for options.

How much does a Floodshield weigh?

A Floodshield weighs only 5kg and so can be carried and fitted by most people from 8 to 80+!

How tall is the Floodshield?

Floodshield is 58cm high, or roughly 2 feet.
