Loose Door Hinge Repair: How to Tighten & Fix
Loose door hinges are caused by screws working their way out over time or wood fibers stripping around old screw holes, usually from frequent door use. A box of replacement wood screws costs $3–8 at any hardware store, and most repairs take under 30 minutes. This guide walks you through tightening, replacing screws, and reinforcing stripped holes so your door closes smoothly and silently again.
Step-by-Step Fix
- 1
Inspect the hinges
Close the door and look at both the top and bottom hinges on the frame side. Check if either hinge pulls away from the door frame or if the door sags on one side. Open the door fully and gently wiggle the edge near each hinge to feel for movement—loose hinges will shift noticeably under light pressure.

Tighten existing screws
Use a Phillips head screwdriver that fits snugly into each screw slot to avoid stripping. Tighten all visible screws in each hinge by turning clockwise, applying steady pressure without forcing. Start with the top hinge, then move to the bottom. Test the door swing after tightening to see if sagging or sticking is resolved.
- 3
Replace stripped screws
If screws spin freely without tightening, remove that screw completely and inspect the hole. Replace it with a new wood screw that is the same length (typically 0.75 to 1 inch) but one gauge size larger—for example, upgrade from a number 6 to a number 8 screw. Insert the larger screw and tighten firmly; the wider shaft will grip the wood fibers more securely.
- 4
Repair enlarged holes
If the hole is too enlarged and even a larger screw won't hold, remove the hinge leaf and fill the hole with wooden toothpicks or matchsticks coated in wood glue. Pack them tightly into the hole, let the glue dry for 1–2 hours, then cut off any protruding wood flush with a utility knife. Reinstall the hinge and screw in the original screw size; it will now grip the new wood fibers.
- 5
Check door alignment
Open and close the door slowly while watching the gaps between the door and frame at the top and bottom. The gaps should be even and consistent; if the door still sags or rubs, loosen the bottom hinge by half a turn and tighten the top hinge by half a turn to level it. Repeat this fine-tuning until the door closes smoothly without binding.
⚠️ Safety Notes
- Always support the door with your hand or a wedge before removing both hinges at once, or the door can fall and cause injury or damage.
- Do not over-tighten screws into wood, as this can strip the hole further or crack the hinge leaf—tighten until snug and stop.
- If the hinge itself is bent or cracked, the entire hinge assembly must be replaced; no amount of screw tightening will fix a damaged hinge.
When to Call a Pro
Call a professional if the door frame wood is split, rotted, or if the hinge mounting holes have shifted so far that hinges no longer align—these issues require frame repair or replacement beyond simple tightening.
Frequently Asked Questions
- Why do door hinges become loose over time?
- Door hinges loosen because wood fibers around screw holes compress and shrink with repeated use and humidity changes, causing screws to gradually back out. Metal hinges and wood expand and contract at different rates, which also contributes to loosening.
- Can I fix a loose door hinge without removing the door?
- Yes, you can tighten most loose hinges without removing the door by simply using a screwdriver to tighten the visible screws while the door is closed. However, if you need to replace a hinge or repair the frame, removing the door makes the job easier and safer.
- What size screws do door hinges use?
- Most residential door hinges use number 6 or number 8 wood screws, typically 0.75 to 1 inch long depending on the hinge depth. Check your existing screws or take a hinge to the hardware store to match the correct size.
- How do I know if my door hinge is permanently damaged?
- A hinge is permanently damaged if it is visibly bent, cracked, or severely corroded, or if screw holes are torn and no longer hold any fastener. Damaged hinges must be replaced entirely; tightening will not restore function.
- How much does it cost to replace a door hinge?
- A replacement residential door hinge costs $4–15 each depending on material and style, so replacing both hinges on a door typically costs $15–40 in parts alone. Doing this repair yourself saves the $75–200 labor cost of hiring a professional.
