Siding isn’t like drywall or brick. It’s often thinner, more flexible, and can be prone to cracking or warping—especially in extreme weather. Vinyl siding, for example, expands and contracts with temperature changes, which means screws can loosen over time if not installed correctly. Wood and fiber cement siding may require pilot holes to prevent splitting, while metal siding demands corrosion-resistant hardware.
Additionally, many siding types have a textured or uneven surface, making it hard to get a flush mount. If your Blink doorbell isn’t mounted level or securely, it can tilt, vibrate in the wind, or even fall off—leading to damage or loss of functionality.
That’s why it’s crucial to use the right mounting technique, hardware, and sealants. Taking the time to do it right the first time saves you from headaches down the road.
Tools and Materials You’ll Need
Before you begin, gather all the necessary tools and materials. Having everything ready will make the process smoother and faster.
Essential Tools
- Cordless drill with drill bits (including a 3/16” bit for pilot holes)
- Screwdriver (Phillips head)
- Tape measure
- Level (a small bubble level works best)
- Pencil or marker
- Stud finder (optional, but helpful if you want to anchor into a stud)
- Smartphone with the Blink app installed
Mounting Hardware and Supplies
- Blink doorbell mounting bracket (included with the doorbell)
- Longer screws (if needed—Blink’s default screws may be too short for thick siding)
- Siding anchors or toggle bolts (for hollow areas behind siding)
- Silicone sealant (clear or exterior-grade)
- Weatherproof electrical tape (optional, for added protection)
- Sandpaper (if smoothing rough siding edges)
Optional but Helpful
- Drill guide or template (you can print one from Blink’s website)
- Caulk gun (for applying sealant neatly)
- Extension ladder (if mounting high up)
- Helper (to hold the doorbell while you work)
Step 1: Choose the Best Location
Picking the right spot is half the battle. A poorly placed doorbell can miss visitors, have weak Wi-Fi, or be easily tampered with.
Ideal Height and Angle
Blink recommends mounting the doorbell at about 48 inches (4 feet) from the ground. This height captures most people’s faces clearly and reduces the chance of accidental damage. Avoid placing it too high—above 60 inches—as it may miss shorter visitors or packages left at the door.
The doorbell should face directly toward the walkway or driveway, not at an extreme angle. A slight downward tilt (about 10–15 degrees) helps improve motion detection and reduces glare from the sun.
Check Wi-Fi Signal Strength
Your Blink doorbell relies on a strong Wi-Fi connection. Before drilling any holes, use your smartphone to check the signal strength at the intended location. Stand where you plan to mount the doorbell and open a video streaming app or run a speed test. If the signal is weak, consider:
- Moving your router closer
- Installing a Wi-Fi extender
- Choosing a different mounting spot
Blink doorbells work best within 30–50 feet of the sync module, which should be connected to your router. Keep this in mind when planning.
Avoid Obstructions and Interference
Don’t mount the doorbell behind trees, bushes, or decorative trim. These can block the camera view or trigger false motion alerts. Also, avoid areas with direct sunlight for long periods—this can cause overheating or washed-out video.
If your door has a storm door, make sure the Blink doorbell doesn’t interfere with its swing. You may need to mount it slightly to the side.
Step 2: Prepare the Mounting Area
Now that you’ve chosen the spot, it’s time to prep the siding for mounting.
Clean the Surface
Use a damp cloth or sponge to wipe away dirt, dust, or mildew from the area where the bracket will go. Let it dry completely. A clean surface helps the sealant adhere better and ensures a tight fit.
Mark the Mounting Points
Hold the Blink mounting bracket against the siding at the desired height. Use a level to make sure it’s straight—this is critical for proper camera alignment. Once level, use a pencil to mark the screw holes.
Pro tip: Place a small piece of masking tape over the area before marking. This prevents the pencil from smudging and makes it easier to see your marks.
Check for Obstructions Behind the Siding
If possible, use a stud finder to check what’s behind the siding. Ideally, you’ll want to anchor into a stud for maximum stability. However, most exterior walls have studs spaced 16 or 24 inches apart, so you may not hit one directly.
If there’s no stud, don’t worry—siding anchors or toggle bolts can provide strong support in hollow areas. Just make sure they’re rated for exterior use and can handle the weight of the doorbell (which is lightweight, but still).
Step 3: Drill Pilot Holes
Drilling pilot holes prevents the siding from cracking or splitting, especially with wood or fiber cement.
Select the Right Drill Bit
Use a drill bit slightly smaller than your screws—usually 3/16” works well for most Blink mounting screws. This creates a snug fit without forcing the material.
Drill Carefully
Hold the drill perpendicular to the siding to avoid angled holes. Drill slowly and steadily. If you hit resistance (like a stud), stop and switch to a longer screw if needed.
For vinyl siding, be extra gentle—too much pressure can crack or warp the panel. If your siding is old or brittle, consider using a siding anchor designed for vinyl.
Clear Debris
After drilling, blow out any dust or debris from the holes. This ensures the screws go in smoothly and the bracket sits flush.
Step 4: Install the Mounting Bracket
Now it’s time to attach the bracket securely.
Apply Silicone Sealant
Before placing the bracket, apply a small bead of clear silicone sealant around the back edges of the bracket. This creates a waterproof barrier and prevents moisture from seeping behind the siding.
Don’t overdo it—too much sealant can squeeze out and look messy. A thin, even line is all you need.
Secure the Bracket
Line up the bracket with the pilot holes and insert the screws. Use a screwdriver or drill with a low torque setting to avoid over-tightening. Over-tightening can crack vinyl or strip the holes in softer materials.
If you’re using siding anchors, follow the manufacturer’s instructions. Typically, you’ll insert the anchor into the hole, then screw into it until it expands behind the siding.
Check Alignment
Once the bracket is attached, use your level again to confirm it’s straight. Adjust if necessary before the sealant dries.
Let the sealant cure for at least 30 minutes (or as recommended on the product label) before attaching the doorbell.
Step 5: Attach the Blink Doorbell
With the bracket in place, it’s time to mount the doorbell itself.
Insert the Battery
Open the battery compartment on the back of the doorbell and insert the included lithium battery. Make sure it’s seated correctly and the compartment snaps shut securely.
Snap the Doorbell into the Bracket
Align the doorbell with the bracket and press firmly until it clicks into place. You should hear a secure snap—this means it’s locked in.
Give it a gentle tug to confirm it’s attached properly. It shouldn’t wobble or come loose.
Adjust the Angle (If Needed)
Some Blink models allow slight angle adjustment. If your doorbell has a swivel feature, tweak it so the camera points directly at the walkway. Avoid extreme angles, as this can reduce motion detection accuracy.
Step 6: Sync and Test the Doorbell
Now that it’s mounted, let’s make sure everything works.
Open the Blink App
Launch the Blink app on your smartphone and log in to your account. If you haven’t set up the sync module yet, follow the in-app instructions to pair it with your Wi-Fi network.
Add the Doorbell
Tap “Add a Device” and select your doorbell model. The app will guide you through the syncing process. You may need to press the sync button on the doorbell (usually located on the back or side).
Test the Live View
Once synced, open the live view in the app. Check for:
- Clear video quality
- Proper field of view (no obstructions)
- Good lighting (avoid backlighting)
Walk in front of the doorbell to test motion detection. The app should send a notification and start recording.
Check Battery Life and Signal
The app will show battery percentage and Wi-Fi signal strength. If the signal is weak, consider relocating the sync module or using a Wi-Fi extender.
Troubleshooting Common Issues
Even with careful installation, you might run into a few hiccups. Here’s how to fix them.
Doorbell Won’t Stay Attached
If the doorbell keeps falling off, the bracket may not be secure. Check that the screws are tight and the sealant has cured. For vinyl siding, consider using a specialized vinyl siding clip or longer screws with washers for better grip.
Poor Video Quality or Lag
This is usually a Wi-Fi issue. Move the sync module closer to the doorbell, or reduce interference by keeping it away from microwaves, cordless phones, or thick walls.
False Motion Alerts
If the doorbell triggers too often, adjust the motion sensitivity in the app. Also, make sure trees, flags, or shadows aren’t causing false triggers.
Water Seeping Behind the Siding
If you notice moisture, reapply silicone sealant around the bracket. For long-term protection, consider installing a small drip edge or weather flap above the doorbell.
Battery Drains Too Fast
Cold weather can reduce battery life. If you live in a cold climate, consider using a Blink Outdoor Battery Pack or switching to a wired model if available.
Maintenance Tips for Long-Term Performance
To keep your Blink doorbell working well:
- Clean the lens monthly with a soft, dry cloth
- Check the sealant every 6–12 months and reapply if cracked
- Replace the battery as needed (typically every 1–2 years)
- Update the app and firmware regularly
- Trim nearby plants that might block the view
