You're managing a new build and want the clean, modern convenience of motorized blinds. But you're worried about messy after-the-fact wiring, unreliable batteries, or costly rework orders that blow your project timeline.
For ultimate reliability, motorized blinds[^1] should be hardwired[^2] during the construction phase. This involves running low-voltage wiring[^3] from a power source to each window, completely eliminating the need for batteries and ensuring consistent, maintenance-free operation for your clients.
In my experience, what makes or breaks a motorized blind installation isn't the final programming, but the decisions made back in the construction phase. I’ve seen projects get delayed for weeks because of wiring issues that could have been prevented. For a project contractor like my partner Emma, pre-wiring[^4] is the cheapest insurance policy you can buy. Getting it right from the start directly determines your delivery efficiency and eliminates the risk of call-backs. A little planning goes a long way.
What wiring is really needed for motorized blinds?
You know you need to pre-wire, but the electrician is asking for specifics you might not have. Getting the location, voltage, and wire type wrong can compromise the entire installation.
You need a low-voltage, 2-core wire run inside a conduit to a specific point inside the planned shade pocket. While you don't need a standard wall outlet, this dedicated low-voltage connection is the key to a professional, hidden installation.
The difference between a smooth installation and a nightmare is often just a few centimeters. Based on hundreds of projects, my team has learned that success comes down to three critical pre-wiring rules. First is the position. The wire should exit from a 20mm (3/4 inch) PVC conduit buried in the wall, with the opening placed about 120mm (4.7 inches) above the window opening and tucked inside the curtain box or shade pocket. An error of just 5cm here can prevent the shade housing from closing properly. Second is the voltage. For residential projects, 24V low-voltage DC is the safest and most efficient choice. For larger commercial buildings, we recommend centralizing the AC-to-DC conversion in a utility closet, which simplifies maintenance across dozens or hundreds of units. Third is redundancy[^5]. You can often run one 1.0 mm² (or 18 AWG) two-core wire to power up to three windows, but always run one extra empty conduit in that bundle. This "dark" conduit is your secret weapon for future-proofing, providing a clean path to install a Zigbee or Matter gateway[^6] later without tearing open the walls.
| Pre-Wiring Specification | Recommendation | Why It Matters |
|---|---|---|
| Location | 120mm above window, inside shade pocket | Ensures the wire is completely hidden and the shade fits perfectly. |
| Voltage | 24V DC (Residential); Centralized AC→DC (Commercial) | Safe to work with, efficient, and simplifies large-scale maintenance. |
| Wire Type | 1.0 mm² (18/2 AWG) 2-Core Wire | Provides sufficient power for multiple shades without being bulky. |
| Redundancy | Include one extra empty conduit per wire run | Future-proofs the installation for smart home gateway upgrades. |
What is the real cost and payback of installing motorized blinds?
Your client sees the price tag and asks if it's worth it. You need to confidently explain the total project cost and justify the investment with tangible, long-term benefits like energy savings.
Professional installation of hardwired blinds typically adds $100 to $300 per window, but this investment provides a clear return. By significantly reducing solar heat gain, these blinds can lower your electric bill and improve home comfort.
Calculating the true cost means looking beyond the price of the blinds themselves. You have to factor in the installation. For a hardwired system, this includes the cost of the low-voltage wire, a central DC power supply, and the electrician's labor. While this sounds like a lot, remember my earlier point: paying for an electrician to run these wires during construction is dramatically cheaper than paying them to retrofit a solution into a finished wall later. That initial meter of conduit can save you hours of labor and patching costs down the road.
The payback comes from energy efficiency. Do blinds lower the electric bill? Absolutely. In the summer, automated shades can be scheduled to close during the hottest parts of the day, blocking solar radiation and dramatically reducing the load on your air conditioning. In the winter, cellular or honeycomb shades in particular create an insulating air pocket that reduces heat loss through the glass. This isn't just a vague claim; it's a measurable reduction in your HVAC system's energy consumption, leading to lower monthly bills and a more comfortable, consistent indoor temperature year-round.
Conclusion
The key to a successful motorized blind installation is planning. By pre-wiring correctly during construction, you ensure a clean aesthetic, flawless reliability, and a future-proof system that adds lasting value and energy savings.
