Sticking, squeaking, sagging, not latching — interior door problems fixed quickly, with no minimum job size.
Interior Door Repair in St. Louis
Most interior door problems in St. Louis — sticking, squeaking, sagging, failing to latch, loose hinges, or broken doorknobs — come down to hinge issues, seasonal wood movement, or hardware that has simply worn out. In most cases the door does not need replacing. FIX St. Louis diagnoses what’s actually wrong, gives you a firm quote, and fixes it — usually in one visit. No minimum job size.
The Door That Gets Overlooked Until It Gets Annoying
Interior doors with hinges are the most common door type in any St. Louis home. Bedroom doors, bathroom doors, closet doors, laundry room doors — they all work the same way: a slab hung on two or three hinges, swinging on a pin. Simple in concept. Prone to a predictable set of problems over time.
Most interior door problems are not door problems. They are hinge problems. The door itself is usually fine — it’s the hardware holding it in the frame, or the frame itself, that has shifted or worn out. Understanding that distinction is what separates a quick, inexpensive repair from an unnecessary door replacement.
FIX St. Louis has been looking at interior doors in St. Louis homes for years. We know the problems that show up in older brick homes in Kirkwood and Webster Groves, and we know the ones that show up in newer construction in Chesterfield and Creve Coeur. The causes are usually the same, and they’re almost always fixable. See why St. Louis homeowners trust us for straight answers before any work begins.
Dr. Steve’s Pro Tip:
Before calling anyone about a sticking interior door, try tightening every hinge screw with a hand screwdriver — not a drill. Over-tightening with a drill strips the holes and makes the problem worse. A snug hand-tight screw on every hinge fixes a surprising number of sticking doors in about five minutes and costs nothing.
Diagnose Your Interior Door Problem
Interior door symptoms usually point to a specific cause. Use this table to identify what’s most likely going on with your door before you do anything else:
| Symptom | Most Likely Cause |
|---|---|
| Rubs at top corner, latch side | Hinge sag — loose hinge screws or stripped screw holes |
| Rubs all along one side | Wood swelling from humidity or house settling |
| Drags on the floor | Hinge sag has pulled door down, or floor level has changed |
| Won’t latch without lifting or pushing | Strike plate is out of alignment with the latch bolt |
| Swings open or closed on its own | Frame is out of plumb — gravity takes the door where it wants to go |
| Creaks or squeaks on every swing | Dry or worn hinge pins needing lubrication or replacement |
| Doorknob is loose or wobbly | Set screw loose, or spindle has worn and no longer seats properly |
Whatever the symptom, we start with the diagnosis before we start the repair. There’s no point in planing a door that’s actually sticking because of loose hinges, or replacing a doorknob when the real problem is a misaligned strike plate.

| Door rubs against floor | Adjust hinges or plane the bottom edge to restore proper clearance. |
| Door rubs against frame sides or top | Identify and correct the binding point — hinge adjustment, planing, or shimming. |

| Hinges are loose | Tighten screws; replace with longer screws to reach framing; fill stripped holes before reattaching. |

| Doorknob needs replacement | Remove old hardware and install new knob or lockset, including proper backset and strike plate alignment. |
| Doorknob bumps into wall | Install door stop — floor-mounted, wall-mounted, or hinge-pin style — to prevent wall and knob damage. |
| Door stops needed or broken | Install new door stops or replace damaged ones; also inspect existing stops for trim damage. |
| Casing trim loose or damaged | Re-secure, repair, or replace interior casing trim around the door frame. |
| Door needs replacement | Source and hang a new interior door slab; adjust frame as needed for proper fit. |
The Most Common Interior Door Problems in St. Louis
Dr. Steve’s Take:
Squeaky hinges made Dr. Steve’s Top 5 Most Overlooked Home Repairs list — not because they’re dramatic, but because they’re the kind of thing people live with for years when a five-minute fix would end it permanently. Dry hinge pins are the most common cause. Lubricate them properly once and you probably won’t think about that door again for years.

Dr. Steve’s Take:
Dr. Steve has written about door latches in the context of the small repairs that actually improve daily life — the ones that seem minor until you’re dealing with a bathroom door that won’t latch or a bedroom privacy lock frozen in place. A doorknob or lockset that doesn’t work properly isn’t just inconvenient. In a bathroom or bedroom, it’s a genuine quality-of-life issue worth fixing.

Simple Maintenance That Keeps Interior Doors Working Longer
Interior doors need very little maintenance — but that little bit matters. Here’s what Dr. Steve recommends. For more home care guidance, visit Dr. Steve’s Tips.
Dr. Steve’s Pro Tip:
Silicone spray on hinge pins, not WD-40. WD-40 is a water displacer and short-term lubricant that evaporates quickly, leaving the metal dry and attracting dust into the barrel. A dry silicone spray or white lithium grease applied once in the fall lasts through the heating season and dramatically reduces hinge wear over time.
| Frequency | What to Do |
|---|---|
| Seasonally | Check every interior door in the house for smooth operation. A door that’s starting to stick or lag is much cheaper to fix early than after the problem compounds. |
| Fall / pre-winter | Lubricate all hinge pins with a dry silicone spray or white lithium grease. This prevents winter squeaks and slows pin wear. |
| Annually | Check hinge screws on every door. Tighten any that have worked loose. If a screw spins without tightening, the hole is stripped — flag it for repair before the hinge starts pulling away from the jamb. |
| As needed | Install door stops on any door where the knob is making contact with the wall. One door stop is far cheaper than drywall repair or a new doorknob. |
