This guide walks you through installing a Blink doorbell without screws using strong adhesive mounts. Perfect for renters or anyone avoiding drilling, it covers prep, mounting, syncing, and troubleshooting for a secure, hassle-free setup.
Key Takeaways
- Use high-quality adhesive mounts: Choose 3M VHB tape or Blink’s official adhesive mount for strong, long-lasting hold on smooth surfaces like wood, metal, or painted walls.
- Clean the surface thoroughly: Wipe the installation area with isopropyl alcohol to remove dust, grease, and moisture for maximum adhesive grip.
- Allow proper curing time: Let the adhesive set for at least 24 hours before attaching the doorbell to ensure it stays firmly in place.
- Test signal strength first: Use the Blink app to check Wi-Fi connectivity at the installation spot to avoid weak signals or disconnections.
- Angle the doorbell correctly: Tilt the mount slightly downward (10–15 degrees) to capture visitors’ faces and avoid glare from sunlight or porch lights.
- Monitor battery life regularly: Since there’s no hardwired power, check battery levels in the app and replace them every 6–12 months depending on usage.
- Know when screws are better: For rough, uneven, or outdoor-exposed surfaces, consider using screws for added security and durability.

The screw-free installation method offers several advantages:
- No permanent damage: Ideal for renters or anyone who wants to avoid drilling.
- Quick and easy setup: Takes under 30 minutes with no tools required.
- Clean, minimalist look: No visible screws or brackets cluttering your entryway.
- Removable and reusable: You can take the doorbell with you when you move (with some adhesive residue cleanup).
However, it’s important to note that adhesive mounts work best on smooth, flat, and clean surfaces. If your doorframe is textured, uneven, or exposed to extreme weather, you may need to consider alternative mounting options or reinforce the setup.
What You’ll Need
Before you begin, gather these supplies to ensure a smooth installation:
- Blink Video Doorbell (2nd Gen or newer recommended)
- Blink adhesive mount (included with the doorbell or available separately)
- 3M VHB double-sided tape (optional, for extra strength)
- Isopropyl alcohol (70% or higher) and a clean cloth
- Measuring tape or ruler
- Pencil or painter’s tape (for marking)
- Smartphone with the Blink app installed
- Wi-Fi network with 2.4 GHz band (required for Blink devices)
Optional but helpful:
- A small level (to ensure the doorbell is straight)
- A helper (to hold the doorbell while you adjust positioning)
- A hairdryer (to soften adhesive if you need to remove or reposition)
Step 1: Choose the Right Adhesive Mount
The Blink Video Doorbell comes with a standard adhesive mount designed for screw-free installation. This mount uses industrial-grade double-sided tape that adheres well to most smooth surfaces. However, for added security—especially in high-traffic areas or extreme climates—you may want to upgrade to a stronger solution like 3M VHB tape.
Understanding Adhesive Options
Blink Adhesive Mount: This is the default option included in the box. It’s pre-applied with strong tape and designed specifically for the Blink doorbell. It works well on painted wood, metal, glass, and smooth plastic.
3M VHB Tape: A premium alternative, 3M VHB (Very High Bond) tape is known for its exceptional strength and weather resistance. It’s commonly used in automotive and construction industries. You can purchase 3M VHB tape rolls or pre-cut pads online or at hardware stores. Look for “3M VHB 4950” or “5952” for best results.
Reusable Adhesive Strips: Products like Command™ Outdoor Strips are designed for outdoor use and can hold up to 16 pounds. While convenient, they may not be as durable long-term as VHB tape, especially in direct sunlight or rain.
Which One Should You Use?
- For most homes: The included Blink adhesive mount is sufficient.
- For high-wind areas or extreme weather: Use 3M VHB tape for extra hold.
- For temporary setups or rentals: Command™ strips offer easy removal with minimal residue.
Tip: If you’re unsure, start with the Blink mount. If it feels loose after a few days, reinforce it with a small piece of 3M VHB tape on the back.
Step 2: Prepare the Installation Surface
The success of your adhesive mount depends heavily on how well you prepare the surface. Even the strongest tape won’t stick to a dirty, oily, or uneven wall.
Clean the Area Thoroughly
- Use a clean cloth and isopropyl alcohol to wipe the area where the mount will go. Focus on removing dust, dirt, grease, and any old adhesive residue.
- Let the surface dry completely—this is crucial. Moisture can weaken the bond.
- If the surface is painted, make sure the paint is in good condition. Peeling or flaking paint will prevent a strong hold.
Check Surface Compatibility
Adhesive mounts work best on:
- Smooth, painted wood
- Metal (aluminum, steel)
- Glass
- Smooth plastic or composite materials
Avoid using adhesive mounts on:
- Textured or rough surfaces (e.g., brick, stucco, concrete)
- Porous materials (e.g., unsealed wood, drywall)
- Surfaces with loose paint or wallpaper
- Areas exposed to constant rain or direct sunlight (unless using weatherproof tape)
Mark the Ideal Position
Use a pencil or painter’s tape to mark where the center of the doorbell will sit. The ideal height is between 48 and 60 inches from the ground—this ensures it captures most visitors’ faces clearly.
Tip: Stand back and look at the angle. You want the camera to point slightly downward (about 10–15 degrees) to avoid glare from the sun or porch lights and to get a better view of packages left at the door.
Step 3: Attach the Adhesive Mount
Now it’s time to secure the mount. Follow these steps carefully to ensure a strong, lasting bond.
Remove the Backing from the Tape
Peel off the protective liner from the adhesive side of the mount. Be careful not to touch the sticky surface with your fingers—oils from your skin can reduce adhesion.
Position the Mount
- Align the mount with your marked spot. Make sure it’s level—use a small level or the grid lines on the mount to check.
- Press firmly on the center of the mount for 30 seconds. Apply even pressure across the entire surface.
- For extra security, press along the edges and corners to ensure full contact.
Let It Cure
This step is often overlooked but critical. Most adhesives need time to reach full strength. Wait at least 24 hours before attaching the doorbell. During this time, avoid touching or moving the mount.
Why wait? Adhesives bond gradually. The initial stick is strong, but the full bond develops over hours as the adhesive molecules interlock with the surface. Rushing this step can lead to failure, especially in hot or cold weather.
Step 4: Install the Blink Doorbell
Once the mount has cured, you’re ready to attach the doorbell.
Insert the Batteries
- Open the battery compartment on the back of the doorbell.
- Insert two AA lithium batteries (recommended for longer life and better performance in cold weather).
- Close the compartment securely.
Attach the Doorbell to the Mount
- Align the doorbell with the mount. The bottom of the doorbell should snap into the lower hook.
- Gently press the top of the doorbell until it clicks into place.
- Give it a light tug to confirm it’s secure.
Tip: If the doorbell feels loose, double-check that the mount is fully adhered. You can also use a small piece of clear tape on the top edge for added security (just avoid covering the camera or sensor).
Step 5: Sync the Doorbell with the Blink App
Now that the hardware is in place, it’s time to connect your doorbell to your home network.
Download and Open the Blink App
If you haven’t already, download the Blink Home Monitor app from the Apple App Store or Google Play Store. Create an account or log in if you have one.
Add a New Device
- Tap the “+” icon in the app and select “Add Device.”
- Choose “Doorbell” from the list.
- Follow the on-screen instructions to scan the QR code on the back of your doorbell.
Connect to Wi-Fi
- Make sure your phone is connected to your 2.4 GHz Wi-Fi network (Blink devices don’t support 5 GHz).
- Enter your Wi-Fi password when prompted.
- Wait for the app to connect the doorbell to your network. This may take 1–2 minutes.
Test the Connection
Once connected, the app will guide you through a quick setup. Test the live view to ensure the camera is working. Press the doorbell button to trigger a notification and check if you receive an alert on your phone.
Step 6: Optimize Placement and Settings
Even with a secure mount, small adjustments can make a big difference in performance.
Adjust the Angle
If the camera is pointing too high or too low, you can slightly reposition the mount before the adhesive fully cures (within the first 24 hours). Use a hairdryer on low heat to soften the tape, then gently adjust the angle.
Enable Motion Zones
In the Blink app, go to your doorbell settings and enable “Motion Zones.” This lets you define specific areas where motion should trigger alerts (e.g., the walkway) and ignore others (e.g., a busy street).
Set Up Chime and Alerts
You can choose to receive alerts on your phone, tablet, or a Blink Sync Module 2 with a built-in chime. Customize notification sounds and sensitivity levels to reduce false alarms.
Troubleshooting Common Issues
Even with careful installation, you might run into a few hiccups. Here’s how to fix the most common problems.
Doorbell Won’t Stick
- Cause: Dirty or incompatible surface.
- Solution: Remove the mount, clean the area again with alcohol, and reapply. Consider using 3M VHB tape for extra strength.
Weak Wi-Fi Signal
- Cause: Doorbell is too far from the router or obstructed by walls.
- Solution: Move your router closer, use a Wi-Fi extender, or install a Blink Sync Module 2 near the doorbell to boost the signal.
Battery Drains Too Fast
- Cause: High motion activity, cold weather, or old batteries.
- Solution: Use lithium batteries, reduce motion sensitivity, or install a Sync Module 2 with a power adapter for continuous power.
Doorbell Falls Off
- Cause: Adhesive wasn’t allowed to cure, or surface was unprepared.
- Solution: Wait 24 hours before reattaching. If it happens again, switch to screw mounting or use a stronger adhesive.
No Notifications
- Cause: App permissions, Do Not Disturb mode, or poor connection.
- Solution: Check app notifications are enabled, ensure your phone isn’t in silent mode, and verify the doorbell is online in the app.
Maintenance Tips for Long-Term Use
To keep your screw-free Blink doorbell working smoothly:
- Clean the lens monthly: Use a microfiber cloth to wipe away dust and smudges.
- Check battery levels: The app will notify you when batteries are low, but check every 3–6 months.
- Inspect the mount: Look for signs of peeling or loosening, especially after storms or temperature changes.
- Update firmware: The app will prompt you when updates are available—keep your device up to date for security and performance.
When to Consider Screw Mounting
While adhesive mounting is convenient, it’s not always the best choice. Consider using screws if:
- Your surface is rough, uneven, or porous.
- You live in an area with high winds, heavy rain, or extreme temperatures.
- The doorbell is in a high-traffic area where it might be bumped or tampered with.
- You want the most secure, long-term installation possible.
The Blink doorbell includes screw holes and mounting hardware in the box, so you can always switch to a screw-mounted setup later if needed.
