What We Do

Complete home weatherization services

We treat your home as a system — sealing leaks, improving insulation, and making every energy dollar count.

Insulation Upgrades

Attic, wall, and crawl space insulation to stop heat loss in winter and keep cool air inside all summer.

Air Sealing

We locate and seal gaps around windows, doors, plates, and penetrations — often the fastest path to savings.

Duct Sealing

Leaky ducts waste conditioned air before it reaches your rooms. We seal and test for better airflow and comfort.

Energy Audits

A thorough assessment pinpoints where your home loses energy so we prioritize the improvements that matter most.

Health & Safety Checks

Combustion appliance testing, carbon monoxide checks, and ventilation review — standard on every HWAP project.

Efficiency Upgrades

LED lighting, smart thermostats, and other measures that stretch your savings even further after the core work is done.
