After getting quotes from three companies, we went with Attico Elevators for our home elevator installation in Delhi. Here is what genuinely impressed us about the process:

Site survey & civil planning (Week 1–2): Attico sent a structural engineer alongside the sales team for the initial visit. They assessed our existing shaft space, floor load capacity, and electrical supply - not just the aesthetics. This is rare. Most companies just sell the product; Attico coordinated with our civil contractor to modify the shaft dimensions before any equipment arrived.

Timeline transparency: We received a written installation timeline broken into phases: civil readiness, equipment delivery, electromechanical installation, testing, and handover. Each phase had a responsible contact person and a WhatsApp update system. When our marble contractor caused a 5-day delay, Attico rescheduled without penalty.

Final testing and commissioning: The commissioning process took a full day - load testing, door cycle tests, ARD simulation, and a safety walkthrough with our family. We received a handover document with all test results.

If you are looking for the best elevator installation experience in Delhi NCR, the differentiator is not the machine - it is the coordination and project management around it. For residential elevators in Delhi, Attico's structured approach made what could have been chaotic feel completely managed.
Happy to answer specific questions about the installation process.
