At Grand Banks, we understand that commercial projects come in all shapes and sizes—from modest renovations to large-scale custom builds. Whether you’re looking for full-package support or need help with a specific window opening, technical drawing, or feasibility study, our team is here to deliver practical, detail-driven solutions from start to finish.
We’ll walk with you through your entire project. From initial design through the final build and beyond. We can provide you with drawings, specifications, design guidance, and alternate products for your job.
Large-scale commercial jobs often require custom sizing, specialized products, and expert coordination. We bring deep knowledge and creative problem-solving to the table, drawing from decades of experience and strong relationships with leading brands like Marvin, Jeld-Wen, Boston Sash, Velux, and Cleary for commercial steel doors. We also work closely with custom fabricators to deliver tailored solutions that meet your design and performance goals.
From technical drawings and shop drawings to real-world mockups and material sourcing, our team provides the resources you need to move forward with confidence. We support feasibility studies, value engineering, and historic approvals with clear, actionable data—always focused on how to replicate existing conditions cost-effectively and with long-term savings in mind.
With commercial timelines stretching months—or even years—our team steps into a true project management role. We coordinate with subcontractors, manage delivery logistics, track inventory and itemizations, and ensure all trades are aligned. We become your point of contact, making sure all stakeholders stay on scope and on schedule.
From small storefront upgrades to landmark restoration, we’ve handled it all. Our process is rooted in communication, transparency, and precision. Every quote we provide is comprehensive—if our number isn’t the lowest, it’s because we include everything you’ll need to finish the job right, without surprise add-ons later.
We meet testing and mockup requirements, support longevity and maintenance planning, and offer both installation services and technical support for third-party installers. Whether we’re drawing from scratch or assembling something from real-world building experience, our secret weapon is knowing how to ask the right questions—and get the right answers.
