How to Tell If Your Attic Needs More Insulation

Image
Key Takeaways If attic insulation is level with or below the floor joists, or leaves joists visible, ENERGY STAR says adding insulation is worth considering. Check several areas: insulation should be spread evenly, including near the eaves, rather than judged by the deepest spot alone. Insulation depth is only a rough guide because R-value depends on the material; Illinois Extension notes that the right R-value varies with climate, home construction, and heating and cooling systems. Seal air leaks before adding insulation, and address wet material, damaged framing, blocked vents, or unsafe wiring first. Keep soffit ventilation paths open, and do not disturb vermiculite insulation during a routine attic inspection. Table of Contents How Do I Know If My Attic Needs More Insulation?

How to Find and Seal Air Leaks Around Exterior Doors

Image
Key Takeaways Check a closed exterior door for visible gaps, then use a hand or dollar-bill test to narrow down where air is passing. Use weatherstripping where the moving door meets its frame; use caulk or another suitable sealant for stationary joints. For concealed gaps between the jamb and wall framing, access and gap size determine whether caulk, backer rod, or suitable foam is appropriate. A door sweep and a well-fitted threshold can reduce air entering beneath the door, but the door must still open and close normally. Water stains, rot, or damaged trim call for checking the water-entry path instead of simply covering the area with sealant.

Home Energy Audit: What to Expect and How to Prepare

Image
Key Takeaways A home energy audit examines how energy moves through a house and helps identify practical improvements to consider first. Prepare recent utility bills and notes about drafts, uncomfortable rooms, and recurring condensation so the assessor can connect measurements with daily conditions. A blower door, infrared camera, or duct leakage test may be used when appropriate, but no single test represents the entire assessment. Ask what the service includes, what the written report will contain, and whether any local program affects the price before scheduling.
