Building Envelope Inspection Services

Understand What's Happening on the Outside of Your Building Before It Becomes a Problem Inside

A commercial building's envelope—including exterior walls, windows, roofing interfaces, sealants, joints, penetrations, and other exterior components—plays an important role in protecting the structure from moisture and environmental exposure.

Small exterior deficiencies can develop into larger problems when they go undetected.

National Drone Systems provides technology-supported building envelope inspection services designed to help property owners and facility managers identify, document, and monitor visible exterior conditions.

Technology-Driven Exterior Inspections

Traditional inspections of elevated façades and difficult-to-access areas can require lifts, scaffolding, or specialized access equipment.

Drone technology can provide an efficient method for visually documenting many of these areas while reducing the need to place personnel in difficult or elevated locations during the initial assessment.

High-resolution imagery can document conditions such as:

• Cracks and visible façade deterioration
• Damaged or deteriorating sealants
• Exterior staining and discoloration
• Window and glazing conditions
• Open joints or visible gaps
• Roofing and flashing conditions
• Water-related exterior observations
• Difficult-to-access building components

Better Documentation. Better Maintenance Decisions.

Inspection imagery can provide facility teams with a documented record of observed building conditions.

This information can help customers prioritize areas requiring additional evaluation, plan maintenance, monitor changes over time, and communicate more effectively with contractors, consultants, engineers, and other building professionals.

From Inspection to Action

Identifying a condition is only the beginning.

NDS can help customers coordinate appropriate next steps through its broader network of building asset professionals and service providers.
