Portland adopted the Maine Uniform Building and Energy Code (MUBEC), which mandates U-Factor ≤ 0.30 for replacement windows in Climate Zone 6. CountBricks estimates automatically filter out products that don’t comply, protecting you from failed inspections. Our platform also flags Efficiency Maine rebates, often worth $40-$60 per qualifying window. We apply those savings directly to your invoice so you see the net price instantly.
A premium triple-pane window can perform worse than builder-grade glass if it’s shimmed or sealed incorrectly. CountBricks crews follow AAMA installation standards and photograph every step for quality control. Our AI checks that rough opening moisture levels are within tolerance before insulation goes in, ensuring long-term durability.
