The 4-Step Installation Process

From first measurement to final smart-home pairing — every stage matters.

1. Measure Accurately

Measure the window opening at three points (top, middle, bottom) for width and the left, center, right for height. Use the smallest measurement for inside mounts.

  • Use a steel tape measure
  • Measure to the nearest 1/8 inch
  • Account for obstructions like handles

2. Prep & Mark Mounting Points

Mark bracket locations level with a pencil. For outside mounts, ensure the headrail overhangs the opening by at least 1.5 inches on each side.

  • Use a level for alignment
  • Locate studs for heavy treatments
  • Use wall anchors for drywall

3. Install Brackets & Headrail

Secure brackets with the appropriate fasteners, then snap or slide the headrail into place. Confirm it's level and operates smoothly before finishing.

  • Pre-drill to prevent splitting
  • Test the lift mechanism
  • Check for bowing across width

4. Wire Motorized Systems

For motorized shades, connect the power supply and pair with the home automation hub. Test remote and app control before finalizing the install.

  • Follow manufacturer wiring specs
  • Pair with smart-home hub
  • Set schedules in the app
FAQ

Common Installation Questions

Inside mount vs. outside mount — which do I need?

Inside mounts sit within the window frame for a clean, built-in look. Outside mounts mount above or on the frame and are ideal for shallow frames or blocking more light.

Can I install motorized shades myself?

Battery-operated motorized shades are DIY-friendly. Hardwired systems that tie into home electrical or smart-home hubs typically require a licensed professional.

How far should drapery extend beyond the window?

For a luxurious look, mount drapery rods 4–8 inches beyond the window frame on each side and 4–6 inches above the top of the frame.
