Frequently Asked Questions
How often should I maintain interior doors?
Inspect interior doors monthly for obvious problems, and perform thorough maintenance annually. Clean doors regularly, lubricate hinges as needed, and address issues like sticking, squeaking, or damage promptly. Annual maintenance includes cleaning, lubrication, hardware inspection, and paint/stain touch-ups.
Why is my door sticking or not closing properly?
Common causes include: humidity changes causing wood to swell, loose hinges, warped door, damaged frame, paint buildup, or improper installation. Start by tightening hinges, then check for warping or frame issues. Humidity-related sticking often resolves when humidity normalizes.
How do I fix a squeaky door?
Squeaky doors are usually caused by dry or dirty hinges. Clean hinges with a rag, then apply lubricant (WD-40, silicone spray, or specialized door lubricant). Work the door back and forth to distribute lubricant. If squeaking persists, hinges may need replacement.
When should I replace an interior door instead of repairing it?
Replace a door if: it's severely warped and can't be fixed, extensive damage exists, repairs are frequent and costly, door doesn't meet your needs, or it's near the end of its expected lifespan. If repair costs approach 50% of replacement cost, replacement is usually more cost-effective.
