🔧 Question 1:

Why does my door suddenly scrape the floor even though it was fine a month ago?

Answer:
A door that once opened smoothly but now scrapes the floor is likely suffering from loose or worn-out hinge screws. Over time, the constant opening and closing motion puts pressure on the top hinge, causing it to sag slightly. As screws loosen or the wood around the screw holes wears out, the weight distribution shifts, and gravity pulls the door downward. Even seasonal changes like humidity can cause wood to swell, worsening the misalignment. Identifying whether it’s the hinge screws or the frame swelling is the first step to solving this.

👉 Ready to see if you’ve grasped this common cause? Test your understanding with the options below.

MCQ Options:

  1. It’s caused by poor door color matching.

  2. It means the floor is uneven.

  3. The top hinge may be loose or the screw holes worn. ✅

  4. It’s due to a misaligned door lock.

Correct Answer: Option 3


🔧 Question 2:

What is the first thing I should check before tightening my door’s hinges?

Answer:
Before grabbing your screwdriver, always inspect which hinge is actually causing the sag. Most commonly, it’s the top hinge, since it bears most of the door’s weight. Open and close the door slowly and watch how it moves—if it dips downward as it swings open, that’s a clear sign of a failing top hinge. Also check if any hinge screws are visibly loose or stripped. Jumping into repairs without assessing the real issue might make things worse.

👉 Think you can spot the right hinge now? Let’s find out—choose below!

MCQ Options:

  1. The handle should be checked first.

  2. The bottom hinge needs tightening by default.

  3. Inspect the top hinge and its screws for sagging. ✅

  4. Remove the entire door to check the frame.

Correct Answer: Option 3


🔧 Question 3:

Why shouldn’t I just keep tightening the same loose screw repeatedly?

Answer:
If a hinge screw keeps coming loose even after tightening, it means the wood behind it is stripped. Re-tightening won’t help long-term because the screw has nothing solid to grip. Instead, insert a matchstick or toothpick dipped in wood glue into the hole, then reinsert the screw. This gives it fresh grip. For heavily worn holes, use longer screws or install a larger diameter screw that bites into fresh wood. This fix helps the hinge stay firm, preventing further sagging.

👉 Time to test if this trick is stuck in your mind—try the MCQ below!

MCQ Options:

  1. Keep tightening until it stops.

  2. Replace the entire hinge.

  3. Use wood glue and toothpicks to refill the screw hole. ✅

  4. Use nails instead of screws for better grip.

Correct Answer: Option 3


🔧 Question 4:

How do I know if my door’s hinge screws are too short?

Answer:
Short screws often only anchor into the door jamb’s surface and not the wall stud, making them easy to loosen. To test this, unscrew one hinge screw and check its length—screws shorter than 1 inch are usually not sturdy enough. Replace them with 3-inch screws, which reach into the framing behind the door and hold the hinge firmly. This small change drastically improves door stability and prevents recurring sag.

MCQ Options:

  1. Screws under 2mm are always best.

  2. Use 3-inch screws to anchor into the wall stud. ✅

  3. Short screws work better in metal frames.

  4. Size doesn’t matter if screws are new.

Correct Answer: Option 2


🔧 Question 5:

What’s the risk of ignoring a sagging door?

Answer:
A door that scrapes the floor isn’t just annoying—it’s actively damaging your home. Continued scraping can leave deep grooves on hardwood or tile, ruining your flooring. Worse, it puts extra stress on the hinges and door frame, which can warp over time, making your door impossible to close or lock properly. In apartments, it can even violate lease terms due to property damage. Fixing the sag early not only saves money but also preserves your home’s integrity and safety.

👉 Now that you know the risk, test your recall—pick the right consequence below!

MCQ Options:

  1. It will stop on its own over time.

  2. It improves door insulation.

  3. It causes floor damage, hinge stress, and frame warping. ✅

  4. It makes the door more secure.

Correct Answer: Option 3


🔧 Question 6:

What should I do if the hinge screws spin in place and won’t tighten?

Answer:
When screws just spin instead of tightening, it means the wood inside the hole is stripped. A simple and effective DIY fix is to use wooden toothpicks or matchsticks dipped in wood glue, stuffed tightly into the screw hole. Let it dry slightly, then reinsert the screw. The added material gives the screw something to bite into, restoring tightness. This trick works especially well if you’re not ready to replace the entire hinge or door jamb, and it prolongs the door’s stability without costly repairs.

MCQ Options:

  1. Hammer the screw deeper.

  2. Use a larger nail.

  3. Fill the hole with toothpicks and glue before reinserting the screw. ✅

  4. Cover the screw hole with tape.

Correct Answer: Option 3


🔧 Question 7:

How do I realign a door that looks crooked in the frame?

Answer:
If your door appears slanted or crooked, it usually means one or more hinges are misaligned. Start by tightening all screws on the top hinge. If the issue persists, try loosening the screws slightly on the opposite hinge to let the door reposition itself naturally. Close the door and observe the spacing around the edges. Aim for an even gap. If necessary, adjust one hinge at a time until the door sits flush in the frame. Minor realignments can drastically improve performance and eliminate the sagging effect.

👉 Think you can balance that door’s alignment? Prove it by selecting the correct step!

MCQ Options:

  1. Paint the frame to make it look even.

  2. Loosen and adjust hinge screws until the door aligns properly. ✅

  3. Trim the bottom of the door.

  4. Replace the entire door.

Correct Answer: Option 2


🔧 Question 8:

Can using the wrong type of screws cause door sagging?

Answer:
Absolutely. Many doors come pre-installed with short or low-quality screws that barely anchor into the frame. These screws loosen easily with regular use, causing the door to sag. You should replace them with long, high-quality wood screws (preferably 3-inch). They reach into the door framing studs and offer better long-term support. Stainless steel or coated screws are better for humid environments, preventing rust. Always make sure screw heads fit flush into the hinge holes to avoid creating additional pressure points.

👉 Now that you know screw quality matters, test what you’ve learned!

MCQ Options:

  1. Screws don’t impact sagging.

  2. Short screws hold better than long ones.

  3. Low-quality screws can loosen and cause sagging over time. ✅

  4. Rusty screws are stronger.

Correct Answer: Option 3


🔧 Question 9:

What if the screw hole is too big even for toothpicks or wood filler?

Answer:
When a screw hole becomes too large to hold even after using wood filler or toothpicks, the best solution is to drill a slightly larger hole and insert a wooden dowel coated in wood glue. Once the glue dries, re-drill a pilot hole into the dowel and insert your screw. This method provides a fresh, strong anchor and restores the door’s stability. It’s a semi-permanent fix that works when quick tricks fail. It’s commonly used by carpenters to reinforce stripped-out wood structures.

MCQ Options:

  1. Fill the hole with cotton.

  2. Insert a glued wooden dowel and re-drill a pilot hole. ✅

  3. Hammer a screw sideways.

  4. Use duct tape to tighten the screw.

Correct Answer: Option 2


🔧 Question 10:

Should I remove the door to fix sagging hinges?

Answer:
Not always. In many cases, you can tighten or replace screws while the door is still hanging. But if the door is too heavy or the sag is severe, temporarily removing it may be safer and more effective. This gives you better access to all hinge points and allows you to reposition or replace them precisely. Use wooden shims or cardboard under the door to protect the floor and help with realignment when reinstalling. So, while it’s not mandatory, it can make the repair process smoother.

👉 Can you decide when door removal is the smart choice? Give it a shot!

MCQ Options:

  1. Always remove the door before any repair.

  2. Never remove the door, even if it’s sagging.

  3. Remove the door only if it’s too heavy or misaligned badly. ✅

  4. Remove the door hinges instead.

Correct Answer: Option 3


🔧 Question 11:

How can humidity affect the door and cause it to scrape the floor?

Answer:
Humidity causes wood to absorb moisture and swell, especially in doors made of solid wood or wooden frames. This expansion can make the door fit more tightly in the frame or even cause it to sag if the hinges can’t support the extra weight. Seasonal changes can worsen this effect, making the door scrape the floor during rainy seasons but loosen in dry months. Proper ventilation and occasionally checking door alignment can prevent long-term damage caused by humidity.

👉 Think you understand the role of humidity? Test yourself below!

MCQ Options:

  1. Humidity causes the door to shrink.

  2. Humidity causes wood to swell and may cause scraping. ✅

  3. Humidity doesn’t affect doors.

  4. Humidity fixes sagging automatically.

Correct Answer: Option 2


🔧 Question 12:

Why might replacing old hinges help with a sagging door?

Answer:
Old hinges can become rusted, bent, or warped, losing their ability to hold the door firmly in place. Even if screws are tight, a damaged hinge won’t support the door’s weight evenly, causing sagging. Replacing hinges with new, sturdy ones—preferably with ball bearing mechanisms for smooth operation—restores stability and ensures the door hangs properly. Make sure the new hinges are the same size and type to fit existing mortises, or adjust accordingly.

👉 Ready to pick out the right reason for hinge replacement? Choose wisely!

MCQ Options:

  1. Old hinges always look better.

  2. Damaged hinges lose grip causing sagging. ✅

  3. New hinges weigh more and cause sagging.

  4. Hinges don’t affect door alignment.

Correct Answer: Option 2


🔧 Question 13:

Can painting or refinishing the door fix scraping caused by sagging?

Answer:
Painting or refinishing might mask surface issues but won’t fix the underlying cause of sagging or scraping. If the door drags on the floor, the problem lies in mechanical alignment—loose screws, worn hinges, or swelling wood—not in surface finish. While repainting after repair is good for aesthetics and protection, always address the root cause first for a lasting fix.

👉 Do you know if paint can fix a sagging door? Test your knowledge!

MCQ Options:

  1. Yes, paint solves sagging problems.

  2. No, paint won’t fix mechanical issues causing scraping. ✅

  3. Paint makes the door heavier causing sagging.

  4. Refinishing removes screws.

Correct Answer: Option 2


🔧 Question 14:

How can I prevent my door from sagging in the future?

Answer:
Regular maintenance is key. Tighten hinge screws periodically, replace any stripped screws with longer ones, and check hinges for rust or damage. Avoid slamming doors as repeated impact loosens hardware. Control humidity with proper ventilation, and if you live in a humid area, consider weatherproof finishes. Installing longer screws in top hinges initially can provide stronger support. Routine checks ensure small issues don’t become costly repairs.

👉 Can you pick the best prevention tips? Try now!

MCQ Options:

  1. Ignore loose screws until door falls off.

  2. Tighten screws regularly and use longer screws in top hinges. ✅

  3. Never open or close the door.

  4. Use nails instead of screws.

Correct Answer: Option 2


🔧 Question 15:

When is it best to call a professional instead of DIY fixing sagging hinges?

Answer:
If the door is extremely heavy, severely damaged, or the frame itself is warped or rotten, a professional carpenter or handyman should be called. Also, if you’re uncomfortable handling tools or if previous repairs have failed, seeking expert help prevents further damage. Professionals can assess underlying structural issues, offer replacements, and ensure safety. Remember, DIY is great for minor fixes, but knowing your limits protects your home and peace of mind.

👉 Do you know when it’s time to get expert help? Select the right scenario!

MCQ Options:

  1. When the door is only slightly loose.

  2. If the door is heavily damaged or frame is warped. ✅

  3. Always call a pro first without trying DIY.

  4. If the door opens smoothly.
