Karl Erickson, President of National Stained Glass Group, on-site at a project

Your Dedicated Advocate on Every Project


Major stained glass projects involve architects, contractors, building committees, and significant budgets. Without independent oversight, it's easy for costs to spiral and quality to slip.

NSGCG serves as your owner's agent — managing every aspect of the stained glass portion of your project. We write the specs, help you choose the right people, and hold everyone accountable to quality and budget.

What We Do

Our Project Management Services

📋

Detailed Specifications

Comprehensive, written specifications that define scope, materials, techniques, and quality standards — the foundation of a well-managed project.

🤝

Vendor Selection Support

Guidance on evaluating proposals, checking references, and selecting the most qualified studios and contractors for your specific project.

🔍

Quality Control Oversight

Regular on-site inspections at critical milestones. We catch problems early and ensure all work meets the specifications — before you sign off.

📅

Timeline Management

Realistic scheduling, milestone tracking, and proactive problem-solving to keep your project on track and your committee informed.

💰

Budget Protection

Independent oversight prevents scope creep and unnecessary change orders. We protect your budget like it's our own — because that's our job.

Final Walkthrough & Acceptance

A thorough final inspection verifying all work meets specifications before final payment is released. Peace of mind that the job is truly done right.
