Ex-E1 Sustainable Building Systems, LLC is a General contractor focused on high-performance construction and upgrades that improve comfort, durability, and energy efficiency. For the best results, request an on-site assessment and a line-item proposal that outlines materials (e.g., insulation R-values and air-sealing methods), schedule milestones, warranties, and how subcontractors are supervised. Ask about their approach to moisture management and code compliance, and request references plus photos of comparable projects. Schedule a consultation to align your budget with energy-saving goals and inquire about available rebates or tax incentives that could lower your total cost.
