Step 1: Turn Off the Power
Safety is paramount when working with electrical systems. Before touching any wires, you must turn off the power to your existing doorbell.
Locate Your Circuit Breaker
Go to your home’s main electrical panel (breaker box). Look for the circuit labeled “doorbell,” “chime,” or something similar. If it’s not labeled, you may need to test circuits by turning them off one at a time and checking if your doorbell stops working.
Turn Off the Correct Circuit
Switch the breaker to the “off” position. Use a non-contact voltage tester at the doorbell location to confirm there’s no power. Simply touch the tester near the wires—if it doesn’t beep or light up, you’re safe to proceed.
Pro Tip: Place a piece of tape over the breaker switch and write “DO NOT TURN ON” to prevent someone else from accidentally restoring power while you’re working.
Step 2: Remove the Old Doorbell (If Applicable)
If you’re replacing an existing doorbell, you’ll need to remove it first.
Unscrew the Faceplate
Use a screwdriver to remove the screws holding the old doorbell to the wall. Gently pull the device away from the wall to expose the wires.
Disconnect the Wires
Take a photo of the wiring setup for reference. Then, loosen the terminal screws and carefully disconnect the two wires. Twist the exposed ends together temporarily to prevent them from slipping back into the wall.
Remove the Mounting Bracket
Unscrew and remove the old mounting bracket. You may need to wiggle it slightly if it’s stuck due to paint or caulk.
Step 3: Choose the Right Location
The placement of your Nest Doorbell affects both functionality and aesthetics.
Ideal Height
Mount the doorbell between 48 and 60 inches from the ground. This height ensures clear video of visitors and prevents tampering.
Centering and Alignment
Position the doorbell directly in front of your door, slightly angled if needed to capture the walkway. Use a level to ensure it’s straight.
Avoid Obstructions
Keep the doorbell away from direct sunlight, rain gutters, or overhangs that could block the camera or cause glare.
Check for Obstructions Behind the Wall
Use a stud finder to scan the area. Avoid drilling into studs, electrical wires, or plumbing. Stucco walls often have metal lath or wire mesh beneath the surface—this is normal, but you’ll need to drill carefully.
Step 4: Mark and Drill the Mounting Holes
Drilling into stucco requires precision to avoid cracking or chipping.
Use the Mounting Bracket as a Template
Hold the Nest Doorbell mounting bracket against the wall at your chosen location. Use a level to ensure it’s straight, then mark the screw holes with a pencil.
Drill Pilot Holes
Attach the carbide-tipped masonry bit to your drill. Set the drill to a low speed and high torque setting. Start drilling slowly at a 90-degree angle to prevent the bit from wandering.
Important: Apply gentle, consistent pressure. Let the drill bit do the work—don’t force it. Stucco is brittle, so aggressive drilling can cause cracks.
Drill Through the Stucco and Lath
You’ll likely feel resistance when the bit hits the metal lath beneath the stucco. Continue drilling slowly until you’ve created clean holes about 1–1.5 inches deep.
Clean Up Dust
Use a vacuum or brush to remove dust and debris from the holes and surrounding area. This ensures a clean surface for mounting and sealing.
Step 5: Run and Prepare the Wires
Now it’s time to connect the wires to your new doorbell.
Feed Wires Through the Bracket
If you removed an old doorbell, the wires should already be accessible. Gently pull them through the center hole of the mounting bracket.
Strip the Wire Ends
Use wire strippers to remove about 1/4 inch of insulation from each wire. Be careful not to cut the copper strands.
Twist the Wires (If Needed)
If the wires are frayed or loose, twist the exposed copper tightly to create a solid connection.
Step 6: Connect the Wires to the Nest Doorbell
The Nest Doorbell uses a simple two-wire connection.
Attach Wires to the Terminal Screws
Loosen the terminal screws on the back of the doorbell. Insert one wire under each screw and tighten securely. It doesn’t matter which wire goes where—Nest Doorbell is not polarity-sensitive.
Secure with Electrical Tape (Optional)
For extra safety, wrap the connections with electrical tape to prevent accidental contact.
Test the Connection (Optional but Recommended)
Temporarily reconnect the wires at the chime inside your home and turn the power back on briefly to test if the doorbell powers up. If it works, turn the power off again before final mounting.
Step 7: Mount the Doorbell Bracket
With the wires connected, it’s time to secure the bracket to the wall.
Insert Wall Anchors
If your stucco is soft or the holes are loose, use plastic wall anchors for added support. Tap them gently into the drilled holes with a hammer.
Secure the Bracket
Align the bracket with the holes and insert the screws. Tighten them just enough to hold the bracket firmly—don’t overtighten, as this can crack the stucco.
Check for Level
Use a level to confirm the bracket is straight. Adjust if necessary before fully tightening the screws.
Step 8: Attach the Nest Doorbell
Now for the final step—mounting the doorbell itself.
Slide the Doorbell onto the Bracket
Align the doorbell with the bracket and slide it down until it clicks into place. You should hear a secure snap.
Secure with the Security Screw
Use the provided security screw and screwdriver to lock the doorbell in place. This prevents theft or accidental removal.
Step 9: Seal the Installation
Stucco is porous and can allow water to seep behind the wall if not sealed properly.
Apply Silicone Caulk
Run a thin bead of silicone caulk around the edges of the mounting bracket where it meets the stucco. This creates a waterproof seal.
Smooth the Caulk
Use your finger or a caulk tool to smooth the bead for a clean, professional finish. Wipe away excess with a damp cloth.
Let It Cure
Allow the caulk to dry completely (usually 24 hours) before exposing it to rain or moisture.
Step 10: Restore Power and Test
Once everything is sealed and secure, it’s time to power up.
Turn the Breaker Back On
Return to the electrical panel and switch the doorbell circuit back on.
Test the Doorbell
Press the button to see if the chime rings and the Nest app on your phone receives a notification. Check the video feed for clarity and proper angle.
Adjust if Needed
If the video is tilted or the angle is off, you can adjust the doorbell slightly by loosening the security screw and repositioning it.
Troubleshooting Common Issues
Even with careful installation, you might run into a few hiccups. Here’s how to fix them.
