Most comfort problems aren’t caused by insulation alone. Drafty rooms, uneven temperatures, high energy bills, and air-quality issues usually come from how your entire home system works together or doesn’t. Adding insulation without testing is often guesswork. Air leaks, pressure imbalances, duct issues, and ventilation problems can remain untouched, limiting real improvement. In some cases, adding insulation alone can even trap moisture or create new problems. That’s why insulation works best after the real issues are identified. Home performance focuses on fixing the root cause, not just adding materials and hoping for results.
