While quite durable, metals are inherently vulnerable to corrosion due to ongoing reactions with environmental factors such as moisture, oxygen, pollutants, and biological agents that lead to gradual deterioration.

Through a rigorous, research-driven approach, EverGreene ensures that historic metalwork is stabilized and preserved, restoring the integrity and appearance while respecting original finishes. Results of material testing and analysis and expertise in historic metalwork guide diagnosing deterioration and developing targeted treatment strategies. Our process typically includes:

• Analysis—Identification of metal types, corrosion mechanisms, and contributing environmental conditions
• Stabilization & Cleaning—Removal of corrosion and contaminants through carefully selected mechanical or chemical methods
• Treatment—Application of corrosion inhibitors, protective coatings, or other tailored interventions
• Documentation—Detailed records of condition, treatment methods, and recommendations for ongoing care

With projects spanning the country, EverGreene brings proven expertise to each metal conservation engagement—explore our portfolio to see the breadth of our work.
