Check Attic Insulation
Why It Matters
Inadequate attic insulation is the #1 source of home energy loss. Proper insulation can cut heating/cooling costs by 20%.
Quick Guide

Perform the check attic insulation
Inspect attic insulation depth and condition, looking for gaps, compression, or moisture. Safety note: Walk only on joists, never between them.

Community Tips
Attic insulation effectiveness depends heavily on depth and density — measure at least five different spots across the attic floor, as settlement and moisture damage often create thin zones that compromise overall R-value performance. Owens Corning fiberglass batts ($40-60 per 16-sq-ft bundle) show visible compression or gaps that indicate replacement is needed in those specific areas.
Asbestos-containing insulation, commonly found in homes built before 1980, poses serious health risks if disturbed — visible signs include loose, crumbly material or labeling mentioning asbestos, and these areas require professional abatement rather than DIY inspection or removal.
A complete attic insulation upgrade typically costs $1,500-$3,000 for an average 1,500-sq-ft home, but spot-treating identified thin zones with Rockwool ComfortBatt ($50-75 per bundle) often solves 60-70% of temperature and energy problems at just 10-15% of full replacement cost. ---
