Insulation Installation
Our insulation services enhance energy efficiency and comfort through customized solutions for modern and historic buildings. We use advanced materials like closed-cell spray foam and Rockwool to meet specific performance needs while preserving architectural integrity. Upgrades reduce heating and cooling costs by up to 40% while improving indoor air quality and moisture control.
Air Sealing
Precision air sealing eliminates energy waste by addressing gaps and cracks in building envelopes. Our technicians use diagnostic testing to identify leakage points before applying specialized sealing techniques that maintain structural integrity while improving energy performance and reducing pest infiltration risks.
Mold Assessment
Our certified mold assessments identify indoor air quality risks through comprehensive testing and analysis. We use specialized equipment to detect hidden moisture issues and mold growth, providing detailed remediation plans that address root causes while maintaining building integrity and occupant health.
Diagnostic Testing
Advanced diagnostic testing pinpoints building performance issues using tools like blower door tests and infrared imaging. This data-driven approach identifies hidden air leaks, insulation gaps, and moisture problems to create targeted improvement plans that maximize energy efficiency and comfort outcomes.
Historic Preservation
Specialized historic preservation services maintain architectural character while modernizing building performance. We implement energy-saving upgrades that comply with preservation standards, using period-appropriate materials and techniques to enhance comfort without compromising historical integrity.
