A door that drags across the floor every time you open it is not a mystery you have to live with. The scraping sound, the visible arc worn into the flooring, the extra shove needed to clear the threshold, these are symptoms with identifiable causes, and each cause points to a different fix. This guide walks through how to find where the rub actually starts, what the five most common root causes look like, and how to work through corrections in the right order so you fix the problem instead of masking it.
What causes a door to rub against the floor? The three most common causes are worn or loose hinge screws that let the door sag over time, seasonal wood expansion from humidity and temperature changes, and structural misalignment in the frame or floor caused by settling. Each leaves a distinct pattern you can identify with a simple visual and tactile check.
Some of these fixes are within reach for a homeowner with basic tools and patience. Others involve frame plumb, floor levelness, or structural settling that go beyond hinge adjustment. Ace Handyman Services works with homeowners at any point in that process, whether you want a second opinion on your diagnosis or want the whole repair handled by a professional.
Quick Overview: Diagnosing and Fixing a Rubbing Door
- Locate the exact contact point on the door and floor using visual marks and a straightedge
- Check whether the rub is one-sided (hinge or frame issue) or affects the full width (warp, floor, or humidity swelling)
- Test hinge screws for looseness and door plumb using a level or straightedge
- Test frame plumb on both jambs to rule out structural twist
- Check the floor itself for heave, settling, or uneven substrate beneath the door swing
- Start with the least invasive fix: tighten hinge screws
- Move to shimming hinges if screws are stripped or tightening does not resolve the rub
- Plane the door bottom only after ruling out hinge and frame causes
- Escalate to a professional assessment if frame or floor issues exceed a quarter inch out of plumb
How to Identify Where Your Door Is Rubbing
How to identify where your door is rubbing: Inspect the door bottom and frame for scuff marks or worn finish, then run your fingers along the contact edge to feel where drag occurs. Use a straightedge against the door and frame to spot gaps or high points. A rub on one side signals hinge or frame trouble; a rub across the full width points to warp, floor issues, or humidity swelling.
Start by watching where the door drags as you open and close it slowly. A mark on the flooring finish, whether it is a dulled patch on hardwood or a worn line in carpet fibers, tells you exactly where contact happens. Note whether the rub happens near the latch side, the hinge side, or evenly across the bottom edge.
Checking Door Height and Level
Hold a straightedge or level against the bottom edge of the door while it is open and compare it to the floor line. If the door bottom is parallel to the floor but sits too low overall, the door has likely dropped uniformly, which usually points to hinge wear or humidity swelling. If one corner sits noticeably lower than the other, the door has twisted or a hinge has failed unevenly.
Testing Frame Alignment and Plumb
Set a level against both sides of the door frame, top to bottom. A frame that reads plumb on one side but leans on the other indicates the frame itself has shifted, often from foundation settling or a poorly shimmed installation. This is a structural signal, not a hinge problem, and hinge adjustment alone will not resolve it. A frame more than a quarter inch out of plumb over three feet warrants a closer look before you spend time on hinge fixes.
Assessing Floor Levelness Beneath the Door
Slide a straightedge across the floor beneath the door swing and check for gaps or high spots with a feeler gauge if you have one. Floors settle, heave, or develop uneven spots from subfloor damage, concrete curing, or moisture damage, and none of that gets fixed by adjusting the door. This is especially relevant over garage entries, basement doors, and exterior thresholds where substrate movement is more common than interior rooms.
Five Root Causes of Door Rubbing and What They Look Like
Why is my door rubbing the floor? The top causes are loose or worn hinge hardware causing sagging, seasonal wood swelling from humidity, frame misalignment from settling, floor heave or substrate irregularity, and door warp. Each shows a distinct pattern: hinge sag rubs progressively, swelling rubs uniformly, and frame or floor issues rub on one side only.
Hinge Failure and Sagging Doors
Hinge wear progresses in stages. Early on, screws simply loosen in their holes, and the fix is as simple as retightening. As wear advances, the screw holes strip and tightening stops holding. In later stages, the hinge pins themselves develop play or the metal fatigues, letting the whole door drop at the latch corner. Wiggle the door gently at the top while it is open; noticeable play at the hinge confirms wear. Sagging typically shows first as a rub at the top corner of the latch side, then spreads downward as the drop worsens.
Wood Expansion Due to Humidity and Temperature
Solid wood doors absorb and release moisture with the seasons, swelling in humid months and shrinking in dry ones. This shows up as a rub that appears across the full width of the door bottom, rather than concentrated on one side, and it tends to come and go with the calendar rather than getting steadily worse. Homes in humid regions see this more severely than homes in arid climates, and it is worth tracking whether the rub disappears in a different season before assuming a permanent cause.
Frame Twisting and Settling
Foundation settling, building shift, or an imperfect original installation can twist a door frame out of plumb over time. This produces a rub confined to one side of the door that persists no matter how much you adjust the hinges, because the problem is not the door, it is the opening itself. A visibly leaning frame, or rubbing that shows up simultaneously on multiple doors on the same level, both point toward a structural cause rather than a hardware one.
Floor Heave and Substrate Issues
Concrete heave, expansive soil, subfloor sagging, or a thick carpet transition can all raise the floor surface enough to catch the bottom of a door that was previously clearing fine. This cause is easy to miss because it has nothing to do with the door or the frame at all. Watch for rubbing that is localized to one section of the door's swing path or that coincides with a flooring change, a garage threshold, or a basement stairwell.
Door Warp or Cup
A warped door bends slightly along its length or across its width, which a straightedge will reveal even when the frame and hinges test out fine. Warp is common in exterior doors exposed to sun on one face and shade on the other, and in interior doors that have taken on moisture unevenly. Pressure from a warped door distributes unevenly across the bottom edge rather than in a single clean line.
- Hinge sag: the rub starts at the top corner and spreads down. You will feel play when you wiggle the open door at the top.
- Humidity swelling: the rub runs the full width and comes and goes with the season.
- Frame twist: the rub sits on one side and persists year round. A level reads the frame out of plumb.
- Floor heave: the rub is confined to a localized section. A straightedge shows a high spot in the floor.
- Door warp: pressure is uneven with no clean contact line. A straightedge laid across the door shows a bow.
Essential Equipment and Materials for This Repair
Primary Equipment: Level, Straightedge, or Both
A 4-foot level covers frame plumb checks and rough door alignment. A metal straightedge, or even a stiff yardstick, works for tighter measurements against the door bottom. Most homeowners already own one or can borrow one rather than renting; this repair rarely justifies a rental tool.
Shims and Screws: Selecting the Right Size
Thin cedar shims work for hinge adjustments; wood shims work for frame gaps. Replacement screws should match the original hinge screw gauge, and longer screws (2.5 to 3 inches) that reach the framing behind the jamb hold better than the short screws often used in factory installation.
Other Materials You Will Need
- Feeler gauge or thin cardboard shims for measuring gaps
- Wood filler for stripped screw holes
- Hand plane or belt sander if planing becomes necessary
- Sealer or primer for any exposed raw wood after planing
- Replacement hinge screws in a longer gauge
If the diagnostic step points toward a frame or floor issue rather than a simple hinge fix, the equipment needs change and the margin for error narrows. A door installation and repair professional carries the plumb bob, jamb spreaders, and shim sets suited to structural adjustments, and can tell within minutes whether your problem is hardware or foundation.
Step-by-Step Fixes for Door Rubbing
How can I fix a door that rubs at the bottom? Diagnose the cause first using a straightedge and level, then work through fixes in order: tighten loose hinge screws, shim the hinges if screws will not hold, and plane the door bottom only if rubbing persists after both. Skipping the diagnostic step risks planing a door that did not need it.
Step 1: Tighten Hinge Fasteners and Hardware
Support the door slightly while working, and tighten the top hinge screws first, then the bottom, then the middle hinge if present. If a screw spins without tightening, the hole is stripped; back it out, insert a wood filler dowel or toothpick with glue, let it cure, then reinstall. This single step resolves a large share of rubbing cases caused by early-stage hinge wear.
Step 2: Shim Hinges to Reset Door Alignment
If tightening does not close the gap, remove one hinge at a time and place a thin cardboard or wood shim behind the hinge leaf before reinstalling. This shifts the door slightly within the frame, lifting the rubbing corner. Add one shim, test the door, and repeat gradually rather than stacking several shims at once, which risks overcorrecting and creating a new gap on the opposite side.
Step 3: Plane the Door Bottom If Rubbing Persists
Planing is a last resort because it removes material permanently and cannot be undone. Only move to this step once hinge tightening and shimming have been tried and the straightedge test confirms the door itself, not the frame or floor, is the source. Aim for roughly 1/8 inch clearance from the floor in dry conditions, up to 1/4 inch for solid wood doors in humid climates to allow for seasonal swelling. Seal any exposed raw wood immediately after planing to prevent uneven future swelling.
Expect noticeable improvement within a week if hinge tightening was the correct fix. Shimming typically takes two or three rounds of small adjustments to dial in. Planing is permanent and should resolve the issue outright if the diagnosis was accurate.
Interior vs. Exterior Doors: Different Causes, Different Solutions
Exterior doors face weather exposure that interior doors do not: rain-driven swelling, UV-driven expansion on the sun-facing side, and temperature swings across a threshold. Weatherstripping and thresholds on exterior doors create their own contact patterns, and clearance standards differ, an exterior door needs a tighter fit to block weather infiltration while still clearing the threshold sweep. Interior doors, by contrast, rub more often from hinge wear or frame settling since they see less direct environmental stress. Climate zone plays a real role here: homes in humid coastal regions see exterior door swelling that homes in arid inland regions rarely encounter.
Should a Door Sweep Touch the Floor?
A properly installed door sweep should make light contact with the floor or threshold, enough to seal against drafts without dragging or creating resistance when the door swings. If the sweep drags heavily or you feel real resistance opening the door, the sweep is set too low or the floor beneath it has shifted, and it needs adjustment rather than removal.
When to Stop DIY Troubleshooting and Seek Professional Help
If the frame reads more than a quarter inch out of plumb over three feet, if the floor shows visible settling or heave, if you notice cracking or separation around the frame, or if multiple doors on the same level are rubbing at once, the problem has moved past hardware and into structural territory. Attempting to plane or shim your way around a structural issue can mask a bigger problem and make the eventual fix more expensive. At this point, reaching out to your local door installation and repair specialist gives you a trained assessment of whether the frame, the floor, or the foundation is the real source.
Special Considerations for Challenging Situations
Older homes with settled foundations, doors over basement stairwells, and exterior doors with damaged thresholds all present rubbing problems that resist standard fixes. A door that has been planed multiple times over its life may not have enough material left to plane again without compromising its structure. In these cases, replacement rather than repeated adjustment becomes the more sensible path, and pairing that decision with a broader look at adjacent flooring conditions often reveals whether the floor itself is contributing to the problem. When a door has been fought with for years, a fresh professional assessment can save time compared to another round of DIY guesswork.
Maintenance and Long-Term Care
Scheduling a brief annual hinge inspection takes minimal time and extends the life of your doors significantly. Check screw tightness once a year, and note any seasonal rubbing pattern so you can distinguish it from a permanent problem before it worsens.
- Tighten hinge screws annually before they progress to stripped holes
- Track whether rubbing changes with the seasons to separate humidity swelling from structural drift
- Keep indoor humidity in a moderate range to reduce wood movement in solid doors
- Watch frame plumb periodically, especially in older homes prone to settling
- Reseal any planed or exposed wood edges promptly to prevent uneven future swelling
Things to Consider Before You Start
- Have you confirmed the rub location with a straightedge, not just a guess? Skipping this step risks fixing the wrong component entirely.
- Is the rub one-sided or full-width? This single distinction determines whether you are looking at hinges and frame or humidity and warp.
- Are you prepared to accept that planing is irreversible? Once material is removed, it cannot be added back.
- Does the frame or floor show signs of settling beyond a quarter inch? That reading moves this from a hardware fix to a structural one.
Understanding the root cause helps you determine whether you can handle this repair yourself or whether it makes more sense to bring in a professional.

Frequently Asked Questions
How do I know if the rub is from the door, frame, or floor?
Use a straightedge on all three surfaces: the door bottom, both sides of the frame, and the floor beneath the swing. Whichever surface shows the gap or high spot when compared to the others is the source. A plumb frame and level floor with an uneven door points to the door itself.
What's the difference between a door rubbing on one side versus both sides?
A one-sided rub usually points to hinge failure or a twisted frame, since the problem originates on one edge of the opening. A rub across the full width more often indicates humidity swelling or door warp, since those causes affect the entire bottom edge evenly.
When should I hire a professional instead of fixing this myself?
If your straightedge and level checks show the frame is more than a quarter inch out of plumb over three feet, or the floor shows settling or heave, the problem has moved beyond hinge adjustment. At that point, professional assessment prevents you from masking a structural issue with a cosmetic fix.
How much does it cost to fix a rubbing door?
Hinge tightening or shimming costs little beyond a few dollars in hardware. Planing adds modest time and a small amount for sealer. Frame or floor corrections involving structural work carry a wider range depending on the extent of settling, so a professional assessment is the best way to get an accurate scope.
Can humidity really cause a door to rub only part of the year?
Yes. Solid wood doors absorb moisture in humid months and release it in dry months, which changes their dimensions enough to create a seasonal rub that appears and disappears. If your rub tracks with the weather rather than steadily worsening, humidity swelling is the likely cause.
Is it normal for a new door to rub slightly at first?
A small amount of contact right after installation can be normal while the door settles into the frame and any factory finish cures. If the rub does not improve within the first few weeks or worsens, treat it as a hinge, frame, or floor issue rather than assuming it will resolve on its own.
