Installing a Radon Mitigation System at my house

I discovered my radon levels were 8x above the safe limit — so I fixed it myself for under $500, saving $2,000 in professional installation fees. Here's the complete DIY guide from start to finish. My radon levels were dangerously high at 8.11 pCi/L (the EPA action level is 4.0 pCi/L). After getting quotes from professional mitigation companies ranging from $1,500–$2,000, I decided to tackle this myself in an old farmhouse with a dirt-floor crawl space. This video walks you through every single step — fan selection, suction testing, crack sealing, PVC piping, wiring, and final validation. Before-and-after radon readings included. ✅ Results: Radon dropped from 8.11 pCi/L → 0.70 pCi/L 🛒 Everything I Used — Parts & Links Radon Fans (Festa Radon) All Festa Radon fans (high suction & high flow — browse all models): https://www.festaradontech.com/collections/fans High Suction Fan I used in this video (Festa AMG Legend Extreme): https://www.festaradontech.com/products/amg-legend-extreme 🔧 Pipe & Fittings PVC One-Hole Pipe Clamps: https://www.festaradontech.com/products/one-hole-pipe-clamp 6 x 3 Fernco Coupler: https://www.festaradontech.com/products/6x-3-fernco-coupler 6 x 4 Fernco Coupler: https://www.festaradontech.com/products/6x-4-fernco-coupler U-Tube Radon System Manometer: https://www.festaradontech.com/products/5-5-u-tube-radon-system-manometer Critter Guard (pipe cap protection): https://www.festaradontech.com/products/critter-guard Radon Eye — Continuous Radon Detector (the one I use): https://amzn.to/41VwYqe Condensation Bypass: https://amzn.to/4kSGumz Outdoor Electrical Kit — Plug-In Option: https://amzn.to/3DW0GDv Outdoor Electrical Kit — Exact One Used in This Video: https://shopradon.com/products/outdoor-electrical-kit Radon Caulk (crack sealing): https://amzn.to/3FyQ7a0 PVC Primer I used: https://amzn.to/4h8xl6s Spray Paint (exterior pipe finish): https://amzn.to/4huZx3P ⏱️ Chapters 0:00 – Introduction & My Radon Test Results 0:33 – Why Radon Fluctuates & Why Sealing Matters 1:14 – Basement Tour & Where to Place the System 1:57 – High Suction vs. High Flow Fans — Which Do You Need? 2:16 – Old Basement & Crawl Space Challenges 3:15 – Strategic Placement for Full Coverage 4:02 – Drilling the Suction Hole in Concrete 4:48 – The Incense Suction Test — Does It Work? 6:09 – Sealing All Basement Floor Cracks 7:46 – Exterior Pipe & Fan Components Overview 8:17 – Festa AMG Legend Extreme Fan Breakdown 9:06 – Condensation Bypass Feature Explained 9:55 – Exterior Pipe Routing & Securing to Siding 11:02 – Step-by-Step Interior Pipe Installation 12:00 – Exterior Fan & Boot Assembly 13:40 – Gluing PVC for a Perfect Air-Tight Seal 14:48 – Oops — Spilled PVC Primer (It Happens) 15:01 – Securing Interior Pipes with Brackets 15:13 – Ensuring Proper Condensation Drainage 15:32 – Final Exterior Assembly & Gluing 17:12 – Wiring the Fan & Installing a Kill Switch 18:01 – First Fan Startup Moment 18:54 – Installing & Reading the Radon Manometer 19:41 – Final Radon Level Results (You'll Be Shocked) 20:09 – Total DIY Cost vs. Professional Quotes ⚠️ Disclaimer: I'm not a licensed radon mitigation professional.
