What Is Weatherization?

Weatherization refers to a set of home improvement measures designed to protect your home from external conditions like heat, cold, wind, and moisture. It includes sealing air leaks, upgrading insulation, and improving ventilation to optimize energy performance and indoor comfort.

Our Weatherization Services

Air Sealing

We locate and seal gaps, cracks, and leaks in your home’s exterior—around doors, windows, plumbing, and ductwork—to prevent energy loss and drafts.

Insulation Upgrades

Boost your home’s thermal performance with high-quality insulation in attics, walls, floors, and crawl spaces. Proper insulation helps regulate indoor temperatures and reduces HVAC load.

Window & Door Weatherstripping

We install or upgrade weatherstripping on windows and doors to block air leaks and improve comfort without needing full replacements.

Duct Sealing & Repair

Leaky ducts can waste up to 30% of your home’s heated or cooled air. We professionally seal and insulate ductwork to restore proper airflow and efficiency.

Moisture & Ventilation Control

Proper airflow and moisture control prevent mold, mildew, and structural issues. We assess and improve your home’s ventilation systems as part of our weatherization strategy.
