Quick Answer
Yes, you can add a peephole to your front door in most cases. Peepholes, also known as door viewers, allow you to see who is outside your door without opening it. Adding a peephole is a relatively simple project that can be done by most homeowners with basic DIY skills and tools. However, if your front door is unusually thick or made from a material like glass, you may need to take extra precautions or hire a professional.
What is a Peephole?
A peephole, also known as a door viewer or door scope, is a small lens installed in an exterior door that allows the occupant to see outside. Peepholes are typically installed at eye level and use a fish-eye lens to provide a wide viewing angle. This allows you to easily see who is at your door without opening it.
Peepholes provide several important benefits:
– Security – You can identify visitors before allowing access to your home. This allows you to keep the door locked against intruders.
– Privacy – You can avoid opening the door to unwanted or unknown visitors. This keeps solicitors and strangers from catching you off guard.
– Convenience – You can see deliveries as they arrive and avoid missed packages. This also allows you to acknowledge neighbors or guests without fully opening the door.
Overall, peepholes are an inexpensive way to boost home security, privacy, and convenience. They have become common features in most exterior doors.
Requirements for Adding a Peephole
Adding a peephole requires making a small hole in your door and installing the viewing device. This is usually a straightforward process for wooden doors between 1-3/4 and 2-inches thick. To add a peephole, you’ll need:
– Peephole unit – The peephole lens and housing that fits into the door hole. This is available at hardware stores.
– 1/2-inch drill bit – Match this size to the peephole housing for installation.
– Utility knife – For trimming away excess material around the peephole.
– Tape measure
– Pencil or marker
– Drill with 1/2-inch bit
– Screwdriver
– Eye and ear protection – For safe operation of the drill.
You’ll also need to consider your door material and thickness. Most peepholes are designed for exterior wooden doors between 1-3/4 and 2-inches thick. If your door is metal, thicker than 2-inches, or made of glass, you may need a different type of peephole.
How to Add a Peephole
Follow these basic steps to add a standard peephole to a wooden exterior door:
1. Measure and mark the location – Peepholes are typically installed about 58-60 inches from the floor, at eye level. Use a tape measure and pencil to lightly mark the 1/2-inch hole location.
2. Drill a pilot hole – Use a very small drill bit first to drill a pilot hole where your peephole will go. This makes drilling the full 1/2-inch hole easier.
3. Drill 1/2-inch hole – With eye and ear protection, use the 1/2-inch bit to drill the full hole for the peephole. Drill straight through to the other side.
4. Test the fit – Insert the peephole in the hole to ensure it fits properly before proceeding. It should fit snugly.
5. Insert and fasten peephole – Place the peephole lens in the exterior side. From the inside, insert the housing and screw it into place according to the manufacturer’s instructions. The housing threads should keep it firmly in place.
6. Trim excess – Use the utility knife to carefully trim away any splintered edges or excess material around the peephole.
7. Test and inspect – Verify that the peephole functions properly by looking through it. Make sure the lens is secure and provides a good field of vision.
With those simple DIY steps, you can successfully add a standard peephole to a typical wooden exterior door. Just be sure to follow any specific directions from the peephole manufacturer as well.
Variations for Unique Doors
For specialty doors that are extra thick, metal, glass, or otherwise unique, you may need to take some additional precautions or use specialized peephole products:
Thick doors
– Longer drill bit – Use the appropriate size bit that matches the thickness of your door. This ensures drilling all the way through.
– Extended peephole – Look for a product designed specifically for thick doors over 2 inches. These feature a longer barrel and lens tube.
Metal doors
– Step drill bit – Start with a smaller pilot hole then gradually increase to the full 1/2-inch hole using a step drill bit. This cleanly cuts the metal.
– Metal reinforcement – Some peepholes for metal doors include a metal sleeve insert to reinforce the hole and secure the housing threads.
Glass doors
– Glass drill bit – Special diamond-tipped drill bits are required to penetrate glass. Never try drilling glass with a standard wood bit.
– Glass peephole – Instead of drilling, adhesive glass peepholes attach to the door surface. These avoid any glass damage.
– Window film – Privay window film adds a one-way view while avoiding any glass holes. This peel-and-stick film easily applies to glass.
For specialty doors or installations, be sure to acquire the proper peephole designed for your specific situation. Carefully read and follow the product instructions. Consulting a professional locksmith is also a good idea for custom doors.
Positioning Your New Peephole
Where you place your peephole matters almost as much as properly installing it. Follow these tips for ideal peephole placement:
– Eye level – Install the peephole at about 58-60 inches above the floor. This allows easy viewing without having to bend or stretch.
– Central – Position the peephole in the center horizontal axis of the door. This provides the widest possible view from side to side.
– Clearance – Make sure exterior decorations, storm doors, or porches don’t obstruct the peephole view. Test the view before permanently installing.
– Lighting – Avoid facing the peephole into direct sunlight or exterior lights. This can cause glare and make viewing difficult.
– Accessibility – Put the peephole low enough for children and those in wheelchairs to use as well. You may want to add a second lower peephole.
Take the time to find the optimal peephole location. This ensures it provides the best possible visibility and convenience for all users.
Security Considerations
While very helpful, peepholes also come with some potential security considerations to keep in mind:
– Two-way viewing – While you can see out, someone outside can also see your eye looking through a standard peephole.
– Blocking – An intruder could potentially block the peephole view with tape or another obstruction.
– Breaking – Although durable, it’s possible for an intruder to break a peephole with force and gain entry.
– Concealing – Make sure the exterior peephole blends with your door and is not obvious from outside.
To further boost security, consider adding a wide-angle viewer, security chain, or smart camera doorbell as well. Taking these extra precautions helps minimize peephole risks.
Conclusion
Installing a peephole is one of the simplest DIY home security projects. In most cases, it just takes a few tools and following basic installation steps. While wooden doors are ideal, peepholes can also work for metal, glass, and thick specialty doors with the proper materials. Just be sure to position the peephole properly to maximize visibility. With minimal effort, a peephole allows you to see who is at your door before opening it. This added peace of mind makes peepholes a worthwhile upgrade for any home.
