The peephole in your front door is gone—either it fell out, was removed by a previous tenant, or was taken during a door upgrade. Now you’re left with a visible hole going all the way through the door. In Evanston, IL, where many rental apartments and older homes have standard peephole-sized holes in their entry doors, this is a common issue that previous tenants or property managers often leave unresolved.
A missing peephole leaves a hole that is typically 1/2 to 5/8 inch in diameter, going completely through the door. This hole lets in light, air, and noise from the outside. It can also be a tripping point during move-out inspections, as landlords expect doors to be returned in their original condition. The good news is that peephole hole repair is straightforward and can be done cleanly with the right approach.

Quick Answer: How Do You Fix a Peephole Hole in a Door?
You have three options: (1) Install a new peephole in the existing hole (easiest and most functional), (2) plug the hole from both sides with wooden dowels and wood filler (best if you don’t want a peephole), or (3) use a decorative plug or cap to cover the hole from one side (quickest cosmetic fix). For hollow-core doors, you may need to pack the hollow interior with filler material before plugging the hole.
Why Peephole Holes Get Left Behind
Previous tenant removal. Tenants sometimes remove peepholes when moving out, either to take them with them or because they were loose and fell out.
Door upgrade or replacement. When a door is upgraded or replaced, the old peephole may be removed but the hole not filled.
Accidental damage. The peephole was bumped, pried, or otherwise damaged and removed, leaving the hole.
Property manager oversight. Between tenants, property managers may not notice or address a missing peephole.
Intentional removal for privacy. Some residents remove peepholes for privacy reasons, preferring not to have a hole through their door.
Repair Options for a Peephole Hole
Option 1: Install a new peephole. The simplest and most functional solution. Buy a replacement peephole (they cost $5–$20) and install it in the existing hole. This restores the door’s functionality and appearance.
Option 2: Plug the hole with wood. For a permanent fill, insert a wooden dowel or plug into the hole from one side, trim flush, fill with wood filler, sand smooth, prime, and paint. For hollow-core doors, you need to pack the interior cavity first.
Option 3: Decorative plug or cap. A decorative wooden or metal plug can be inserted into the hole from one side for a quick cosmetic fix. This doesn’t seal the hole from the other side.
Option 4: Epoxy fill. For a strong, permanent fill, use two-part epoxy to fill the hole from both sides. This works well on both solid-core and hollow-core doors.
Can You Fix It Yourself?
Yes, all four repair options are DIY-friendly. Installing a new peephole is the easiest—just push or screw it into the existing hole. Plugging with a wooden dowel requires basic tools (drill, dowel, wood glue, filler, sandpaper). Epoxy fill requires mixing and applying two-part epoxy but creates the strongest repair.
The main challenge with hollow-core doors is that the hole goes into an empty cavity. You need to pack the cavity with filler material (crumpled paper, foam, or epoxy) before plugging the hole, otherwise the plug has nothing to grip.
Tools and Materials Needed
- Replacement peephole. If choosing Option 1.
- Wooden dowel or plug. Sized to fit the peephole hole diameter.
- Wood glue. For securing the dowel or plug.
- Wood filler or two-part epoxy. For filling gaps and smoothing the repair.
- Sandpaper (120–220 grit). For smoothing the repair.
- Primer and paint. For finishing the repair to match the door.
- Utility knife. For trimming excess material.
- Crumpled paper or packing material. For filling the hollow cavity in hollow-core doors.
Step-by-Step: Plugging a Peephole Hole
Step 1: Clean the hole. Remove any debris, old adhesive, or peephole fragments from the hole.
Step 2: Pack the cavity (hollow-core doors only). Stuff crumpled paper or packing material into the hollow cavity through the hole. This gives the plug something to grip.
Step 3: Insert the plug. Apply wood glue to a wooden dowel or plug that fits the hole. Insert it from one side until it meets the packing material or the opposite side of the door.
Step 4: Trim flush. Once the glue is dry, trim the plug flush with the door surface using a utility knife or sandpaper.
Step 5: Fill and smooth. Apply wood filler or epoxy over the plug. Let dry, then sand smooth.
Step 6: Prime and paint. Prime the repaired area, then paint to match the door finish.
When DIY Is Not Enough
The hole is larger than standard. If the peephole hole has been enlarged by damage, a custom repair may be needed.
The door is a metal or fiberglass door. These require different repair materials and techniques than wood doors.
You need a flawless finish. If the door is a high-visibility entry door and you need a perfect paint match, a professional can achieve better results.
How a Handyman Repairs It Properly
A professional will assess the door type, hole condition, and your preference (new peephole vs. filled hole). For Evanston rental properties, we commonly install a new peephole to restore the door to its original condition for move-out inspections. For homeowners who prefer no peephole, we use epoxy-based repairs that are strong, clean, and paintable.
We also check for related issues—is the door in good overall condition? Are there other holes or damage that should be addressed at the same time?

FAQ: Peephole Hole Repair
Q: How much does it cost to fill a peephole hole?
A: Filling a peephole hole typically costs $50–$100 including materials and labor. Installing a new peephole is similar in price.
Q: Should I fill the hole or install a new peephole?
A: Installing a new peephole is more functional and often expected by landlords. Filling the hole is better if you don’t want a peephole for privacy reasons.
Q: Can I fill a peephole hole with caulk?
A: Caulk is not ideal for a through-hole. It won’t provide a solid fill and may not adhere well inside the hollow cavity. Use wood filler, epoxy, or a wooden plug instead.
Q: Will filling a peephole hole weaken my door?
A: No. A properly filled peephole hole does not affect the structural integrity of the door. The hole is too small to matter structurally.
Q: My landlord wants the peephole replaced. What should I do?
A: Install a standard replacement peephole. They are inexpensive and widely available. If you’re unsure about the installation, a handyman can do it quickly.
Q: Can I paint over a new peephole?
A: No. The peephole lens should remain clear. You can paint the door around the peephole, but avoid getting paint on the lens itself.
Q: How long does peephole hole repair take?
A: Installing a new peephole takes 5–15 minutes. Filling and painting the hole takes longer due to drying time (typically 2–4 hours total, or two visits for paint drying).
