The Smart Value of a Leedan Intercom System Retrofit

Complete hardware tear-outs are a relic of the past. Choosing a precise technical retrofit offers substantial real-world advantages for New York City property managers, co-op boards, and building owners alike.

💰 Significant Cost Advantages

​A complete system overhaul requires massive capital. By adapting modern digital components to fit your building's current structural footprint, a retrofit delivers an enterprise-grade upgrade at a fraction of the cost of a full replacement.


🏢 Preservation of Building Infrastructure


Avoid months of messy drilling, dust, and disruptions. Our technicians map modern, high-definition intercom capabilities straight onto your existing low-voltage wiring pathways, leaving your architectural aesthetics untouched.

📱 Smartphone & Remote Cloud Access

Bring your property into the digital age. Retrofitted units can readily bridge into advanced features like crisp HD video feeds, smartphone app unlocks for residents, and remote, cloud-based tenant management platforms.
