Building Sealing Services
Improve energy efficiency, indoor air quality, and long-term building performance with professional building sealing across Minnesota.
A Tighter Building Starts With Proper Sealing
Building sealing focuses on closing gaps, cracks, and openings in the building envelope to control unwanted airflow. These leaks often occur around windows, doors, electrical outlets, light fixtures, ductwork, and structural penetrations.
Crescent Moon Insulation provides comprehensive building sealing services designed to reduce drafts, improve comfort, and enhance overall energy efficiency. By properly sealing the building envelope, we help prevent moisture intrusion, reduce air leakage, and support a healthier indoor environment.
Improved Energy Efficiency
Reduces air leakage and lowers heating and cooling costs.
Enhanced Indoor Air Quality
Limits dust, allergens, and pollutants entering the building.
Moisture Control
Helps prevent condensation, mold growth, and structural damage.
HVAC Performance Support
Sealed ducts and penetrations improve system efficiency.
Air Leaks Drive Energy Loss
Unsealed gaps in walls, roofs, floors, and foundations allow conditioned air to escape and unfiltered outdoor air to enter. This increases heating and cooling costs, places strain on HVAC systems, and can lead to moisture-related issues such as mold and pest intrusion.
Building sealing is a critical step in improving energy performance. When combined with proper insulation, sealing helps buildings maintain consistent temperatures and operate more efficiently year-round.
Building Assessment
We identify air leaks and problem areas throughout the building envelope.
Sealing Plan
A targeted plan is developed using the appropriate sealing methods.
Professional Application
Weatherstripping, caulking, foam sealing, and duct sealing are applied as needed.
Final Verification
We confirm improved airtightness and overall performance.
