Imagine a chilly winter night—you're bundled in blankets, yet drafts still creep through unseen gaps around doors and windows. Or picture a sweltering summer day when your AC struggles against rising energy bills, with poorly sealed openings being the likely culprit. Weatherstripping, though often overlooked, plays a crucial role in maintaining home comfort and energy efficiency.
Weatherstripping refers to narrow materials that seal gaps around movable building components like doors and windows. Its primary functions are preventing outdoor air, moisture, and pests from entering while retaining conditioned indoor air. Proper weatherstripping selection can significantly impact:

Weatherstripping projects typically range from $130 to $430 depending on materials and labor. Simple adhesive-backed products cost $3-$10 per linear foot, while premium options like interlocking metal systems reach $15-$30 per foot.
DIY installation suits adhesive types and door sweeps, potentially saving 50-70% on labor. Complex systems like tubular gaskets or threshold replacements often require professional expertise to ensure proper sealing.
Inspect weatherstripping biannually—before winter and after spring storms. Most materials last 3-5 years, with these replacement signs:
In harsh climates, consider replacing every 2-3 years for optimal performance. Always clean surfaces thoroughly before installing new weatherstripping to ensure proper adhesion.
