Blackstar Aluminum Ltd Toronto
Most reviewers praise Blackstar's professionalism, clean work, and reliable gutter systems with guards that eliminate yearly maintenance. However, recent complaints reveal serious flaws: one customer's gutters were installed backwards (sloping away from downspouts), causing standing water and dirt buildup, and the company ignored repeated requests for fixes since August. Pat and the crew earn consistent praise for responsiveness, on-time service, and attention during siding and soffit work. The gutter guards genuinely perform as promised when installed correctly. A separate complaint flags an undisclosed $3000 minimum job threshold. The installation error and non-responsiveness expose a gap between brand promise and execution on critical details.
