Four categories of flood protection
Whether you’re in a flood zone or not, proactive measures dramatically reduce risk and damage. Each category links to detailed guides, product recommendations, and vetted installers.
Water Diversion
Grading, swales, French drains, and landscaping strategies to redirect water before it reaches your home.
Entry Protection
Flood barriers, door seals, window covers, and sump pump systems to stop water at the point of entry.
Water Removal
Sump pumps, backup power, drainage systems, and rapid-response tools to remove water quickly if it enters.
Structural Protection
Elevating utilities, sealing foundations, waterproof materials, and retrofitting for long-term resilience.

Real stories from people who’ve used Oiriunu to understand and act on their flood risk.
“I had no idea I was in a flood zone until I ran the assessment. We installed a sump system and applied for a FEMA grant within a month.”
“The prevention plan gave us a clear priority list. We started with the cheap wins and are now fully protected for under $3,000.”
“Our insurer had declined us twice. Oiriunu connected us to a private flood carrier we’d never heard of. We’re now fully covered.”
