    Did Your Insulation Contractor BLOCK Your Soffit Vents?

    Send us Fan Mail Is your attic insulation causing higher energy bills? Discover why blocking soffit vents ruins your home cooling efficiency. Many homeowners struggle with an overheated upstairs without realizing the culprit is poor attic ventilation. This video explains how insulation contractors often inadvertently block soffit vents during installation, trapping heat and preventing your home from breathing properly. We walk through exactly what happens when these vents are obstructed and why it matters for your comfort. You will learn how to identify if your airflow is compromised and what to look for when inspecting your attic insulation. By understanding the relationship between blown-in insulation and soffit vents, you can prevent unnecessary repairs and stop overpaying for cooling. We break down the visual signs of improper installation so you know exactly what to check after your next service. 🛠️ PRODUCTS FOR ATTICS: • Spray Foam Kits - https://supply.crawlspaceninja.com/collections/insulation  • Attic and crawl space fans - https://supply.crawlspaceninja.com/collections/fans • Attic Hatch cover - https://amzn.to/4nwUMtj • Solar Attic Fan - https://amzn.to/2Le6o4U • Radiant Barrier - https://amzn.to/4ohWfnK • Recessed Light Cover - https://amzn.to/3ft67ch • Flir C2 Thermal Imaging Camera: https://amzn.to/2Wc5CKO • Smoke Pen: https://amzn.to/49bUS69  • Laser Temperature Meter: https://amzn.to/4qT34hZ 🆓 FREE Attic Air Seal & Insulate Guide: 👉 https://buymeacoffee.com/csninja/e/478323 📖 Seal First, Insulate Second:  👉 https://buymeacoffee.com/csninja/e/546355 🛒 DIY Store — Professional-Grade Materials: 👉 https://supply.crawlspaceninja.com 📞 Book a Personal Consultation with Michael: 👉 https://buymeacoffee.com/csninja **Disclaimer:** This information is for educational purposes only.

    Hot Bonus Room? A Mini Split May Not Be the Answer

    Send us Fan Mail Is your bonus room over the garage always hot in the summer, even though your air conditioner seems to be working fine? Many homeowners are told to install a ductless mini split, but that may only treat the symptom instead of fixing the real problem. Before you spend thousands of dollars on another HVAC system, it's important to understand why bonus rooms become uncomfortable in the first place. In this video, Michael Church from Crawl Space Ninja explains why knee walls, attic air leaks, poor insulation, leaky ductwork, and attic ventilation problems often cause bonus rooms to overheat. You'll learn when a mini split is a smart solution, when it isn't, and why fixing your attic first can improve comfort, lower energy bills, and help your HVAC system perform the way it was designed. 🛠️ PRODUCTS FOR ATTICS: • Spray Foam Kits - https://supply.crawlspaceninja.com/collections/insulation  • Attic and crawl space fans - https://supply.crawlspaceninja.com/collections/fans • Attic Hatch cover - https://amzn.to/4nwUMtj • Solar Attic Fan - https://amzn.to/2Le6o4U • Radiant Barrier - https://amzn.to/4ohWfnK • Recessed Light Cover - https://amzn.to/3ft67ch • Flir C2 Thermal Imaging Camera: https://amzn.to/2Wc5CKO • Smoke Pen: https://amzn.to/49bUS69  • Laser Temperature Meter: https://amzn.to/4qT34hZ 🆓 FREE Attic Air Seal & Insulate Guide: 👉 https://buymeacoffee.com/csninja/e/478323 📖 Seal First, Insulate Second:  👉 https://buymeacoffee.com/csninja/e/546355 🛒 DIY Store — Professional-Grade Materials: 👉 https://supply.crawlspaceninja.com 📞 Book a Personal Consultation with Michael: 👉 https://buymeacoffee.com/csninja **Disclaimer:** This information is for educational purposes only.

    Why Your Bonus Room Is Always Hot

    Send us Fan Mail Is your bonus room always hot in the summer and freezing in the winter? Most homeowners are told to add more insulation, replace the windows, or install a bigger HVAC system. Unfortunately, those expensive fixes often miss the real problem. In this video, I explain the building science behind uncomfortable bonus rooms and show you why air sealing is almost always the first step. You'll learn where conditioned air escapes, how knee walls affect comfort, and why sealing before insulating can make a dramatic difference. In this video you'll learn: • Why bonus rooms get so hot • The hidden problem behind knee walls • Why insulation alone doesn't solve it • Common myths that waste money • The correct order: air seal first, insulate second If you're dealing with an uncomfortable room over your garage, this video will help you understand the real cause before spending thousands on the wrong solution. 🛠️ PRODUCTS FOR ATTICS: • Spray Foam Kits - https://supply.crawlspaceninja.com/collections/insulation  • Attic and crawl space fans - https://supply.crawlspaceninja.com/collections/fans • Attic Hatch cover - https://amzn.to/4nwUMtj • Solar Attic Fan - https://amzn.to/2Le6o4U • Radiant Barrier - https://amzn.to/4ohWfnK • Recessed Light Cover - https://amzn.to/3ft67ch • Flir C2 Thermal Imaging Camera: https://amzn.to/2Wc5CKO • Smoke Pen: https://amzn.to/49bUS69  • Laser Temperature Meter: https://amzn.to/4qT34hZ 🆓 FREE Attic Air Seal & Insulate Guide: 👉 https://buymeacoffee.com/csninja/e/478323 📖 Seal First, Insulate Second:  👉 https://buymeacoffee.com/csninja/e/546355 🛒 DIY Store — Professional-Grade Materials: 👉 https://supply.crawlspaceninja.com 📞 Book a Personal Consultation with Michael: 👉 https://buymeacoffee.com/csninja Videos: Common Mistakes That Make Your Bonus Room TOO HOT https://youtu.be/uytb3wYmftU Your Ducts Are Leaking and You Don't Even Know It https://youtu.be/NfTSBC46MhI **Disclaimer:** This information is for educational purposes only.

    That New Attic Insulation? It's Probably Installed Wrong

    Send us Fan Mail You can drop thousands on blown-in attic insulation and still live with drafts, a scorching second floor, and energy bills that refuse to budge. The uncomfortable truth is that insulation is not an air barrier. If air can move through your attic floor, fiberglass will not stop it, it will only hide it. We walk through the one rule that changes everything for home energy efficiency: seal first, insulate second. We break down how the stack effect turns your house into a chimney, pushing warm air out through attic leaks in winter and pulling hot attic air down into living space in summer. Then we get specific about where those leaks actually are: top plates along every wall, recessed can lights, plumbing and wiring penetrations, attic hatches that fit like loose drywall, and even gaps around HVAC boots. We also talk about indoor air quality, because the same airflow that wastes conditioned air can drag dust and insulation particles into your home. To prove the point, we share a blower door test case study where air leakage stayed exactly the same before and after adding insulation. That is why skipping attic air sealing can become the most expensive shortcut: fixing it later may require vacuuming out new insulation just to reach the leaks you needed to seal in the first place. We close with a simple checklist mindset: air seal, confirm attic ventilation from soffit to ridge, then insulate to the right level for your climate zone (often around R49). 🆓 FREE Attic Air Seal & Insulate Guide: 👉 https://buymeacoffee.com/csninja/e/478323 📖 Seal First, Insulate Second:  👉 https://buymeacoffee.com/csninja/e/546355 🛒 DIY Store — Professional-Grade Materials: 👉 https://supply.crawlspaceninja.com 📞 Book a Personal Consultation with Michael: 👉 https://buymeacoffee.com/csninja 🛠️ PRODUCTS FOR ATTICS: • Spray Foam Kits - https://supply.crawlspaceninja.com/collections/insulation  • Attic and crawl space fans - https://supply.crawlspaceninja.com/collections/fans • Attic Hatch cover - https://amzn.to/4nwUMtj • Solar Attic Fan - https://amzn.to/2Le6o4U • Radiant Barrier - https://amzn.to/4ohWfnK • Recessed Light Cover - https://amzn.to/3ft67ch • Flir C2 Thermal Imaging Camera: https://amzn.to/2Wc5CKO • Smoke Pen: https://amzn.to/49bUS69  • Laser Temperature Meter: https://amzn.to/4qT34hZ **Disclaimer:** This information is for educational purposes only.

    Knee Wall Insulation: Why Finished Attic Rooms Are So Hot!

    Send us Fan Mail Is your finished attic, bonus room, or room over the garage always hotter than the rest of the house in summer and colder in winter? Most homeowners assume they need a bigger HVAC system, but the real problem may be hiding behind a knee wall in the attic. In this video, Michael Church from Crawl Space Ninja explains one of the most overlooked attic insulation and air sealing problems: open floor cavities behind knee walls. You'll learn why fiberglass insulation alone often fails, what building scientists call "wind washing," how attic air sneaks under your floor, and why many contractors miss this critical detail. You'll also learn: ✅ What a knee wall is ✅ Why finished attic rooms are uncomfortable ✅ How open floor cavities affect HVAC performance ✅ Common ductwork problems behind knee walls ✅ The proper way to insulate and air seal a knee wall assembly ✅ Why you should check the building envelope before replacing HVAC equipment If you're struggling with a hot upstairs room, high energy bills, or poor comfort in a finished attic space, this video may save you thousands of dollars. 🆓 FREE Attic Air Seal & Insulate Guide: 👉 https://buymeacoffee.com/csninja/e/478323 📖 Seal First, Insulate Second:  👉 https://buymeacoffee.com/csninja/e/546355 My Favorite Radiant Barrier — US Energy Products 👉 https://amzn.to/4vnRixQ 🛒 DIY Store — Professional-Grade Materials: 👉 crawlspaceninja.com/supply 📞 Book a Personal Consultation with Michael: 👉 https://buymeacoffee.com/csninja Support the show Check out Michael's book, "Crawl Space Repair Myths-Busted" now available on Amazon!

    Attic Ventilation Explained: Soffit Vents, Ridge Vents, and Why Your Attic Still Gets Hot

    Send us Fan Mail Is your attic hot even though you have ridge vents, soffit vents, or even a powered attic fan? You're not alone. Many homeowners spend thousands on attic ventilation upgrades and still end up with high energy bills, uncomfortable rooms, and overheating HVAC systems. In this video, I explain how attic ventilation actually works, why balanced airflow matters, and the biggest mistakes I see during attic inspections. You'll learn the difference between soffit vents, ridge vents, gable vents, and powered attic fans—and why more ventilation is not always better. Most importantly, I'll show you why ventilation is only one part of the equation and why air sealing should always come before insulation and ventilation. In this video you'll learn: ✅ Why attics get hot ✅ How soffit vents and ridge vents work together ✅ Why gable vents can create airflow problems ✅ When attic fans help—and when they hurt ✅ Why air sealing is more important than most homeowners realize ✅ The "Seal First, Insulate Second, Ventilate Third" approach 🆓 FREE Attic Air Seal & Insulate Guide: 👉 https://buymeacoffee.com/csninja/e/478323 📖 Seal First, Insulate Second:  👉 https://buymeacoffee.com/csninja/e/546355 My Favorite Radiant Barrier — US Energy Products 👉 https://amzn.to/4vnRixQ 🛒 DIY Store — Professional-Grade Materials: 👉 crawlspaceninja.com/supply 📞 Book a Personal Consultation with Michael: 👉 https://buymeacoffee.com/csninja Support the show Check out Michael's book, "Crawl Space Repair Myths-Busted" now available on Amazon!
