Professional Stained Glass Appraisals
Accurate, independent valuations for insurance, estate, market, and replacement cost — trusted by churches, collectors, and institutions nationwide.
Know the True Value of Your Stained Glass
Many stained glass windows are significantly underinsured — sometimes by hundreds of thousands of dollars. An outdated or incomplete valuation puts your organization at serious financial risk.
NSGCG delivers professional, defensible appraisals prepared with deep industry expertise. Whether you need documentation for insurance, estate planning, donation, or sale — we provide comprehensive written reports that stand up to scrutiny.
Appraisals Tailored to Your Needs
Every stained glass appraisal is unique. We offer several types of valuations, each carefully prepared to meet your specific requirements.
Insurance Appraisals
Replacement cost valuations that ensure your windows are properly covered. Essential for churches and institutions with significant stained glass assets.
Fair Market Value
Accurate market valuations for buying, selling, or transferring stained glass. Defensible documentation that holds up in any transaction.
Replacement Cost
What would it cost to recreate your window today? Essential for insurance coverage and disaster planning, based on current material and labor costs.
Antique & Historic Valuation
Specialized appraisals for historically significant or antique stained glass, factoring provenance, artist attribution, and historical context.
Church & Institutional
Comprehensive appraisals for houses of worship and institutions — often involving multiple windows, large-scale documentation, and building committee coordination.
Estate & Donation
Professional valuations for estate planning, tax purposes, and charitable donations. Documentation prepared to meet IRS and legal requirements.
What Determines the Value of Stained Glass?
Multiple factors influence valuation. Our experts evaluate each element to deliver an accurate, defensible appraisal.
Why Independent Appraisals Matter
A studio that offers "free appraisals" has a built-in incentive to recommend work — their own work. That's not an appraisal; it's a sales pitch.
NSGCG provides truly independent valuations. We have no ties to any studio, no products to sell, and no restoration work to bid on. When we tell you a window is worth $50,000 — or that it needs $200,000 in restoration — you can trust those numbers.
- No conflicts of interest — ever
- Defensible reports accepted by insurance carriers
- Documentation suitable for legal and estate purposes
- Honest assessment of condition and urgency
