  • Vapor barrier installed in a crawlspace to prevent moisture infiltration, improve energy efficiency, and protect the home from water damage and mold growth

    Crawlspaces & Basements

    Encapsulating a crawl space extends the building envelope to the foundation walls and floor, improving energy efficiency and mechanical system performance. It regulates temperature and humidity to match the home’s interior, preventing musty air from entering through the stack effect. This also enhances moisture control and increases the foundation’s durability.

  • Attic top plates air-sealed with foam insulation to prevent air leaks, improving energy efficiency and reducing heating and cooling costs

    Attic Air-Sealing

    Sealing air leaks with caulk, spray foam, and weather stripping is a cost-effective way to improve energy efficiency and comfort. While drafts around windows and doors are noticeable, the most significant leaks are often hidden in attics, crawlspaces, and basements—leading to higher energy bills and discomfort. Properly sealing these areas ensures a more efficient, comfortable home year-round.

  • Insulation batts installed in an attic with the proper R-value, ensuring optimal energy efficiency and maintaining comfortable indoor temperatures

    Insulation

    Maximize your home's energy efficiency and comfort with expert sealing and insulation. We assess and seal air leaks before installing the right insulation—fiberglass, blown cellulose, rigid foam board, or spray foam—for optimal performance. Proper installation ensures lower energy bills and a more comfortable home. Trust our experts for precision and lasting results.

  • Upgraded outside dryer vent ensuring proper ventilation, improving airflow, reducing moisture buildup, and enhancing energy efficiency

    Fresh Air Ventilation

    Optimize indoor air quality and efficiency with the right ventilation system. An Energy Recovery Ventilator (ERV) exchanges stale air for fresh while minimizing energy loss. It pre-cools and dehumidifies in warm months and pre-heats and humidifies in colder months, ensuring comfort and efficiency. Proper bath fans and dryer vents remove excess moisture and improve airflow. Our experts will help you choose the best solution for a healthier, more efficient home.
