If your garage door won't open, you're not alone. A stuck or jammed garage door is one of the most common problems we handle on Mercer Island. The good news: many causes are fixable without a full replacement, though some require professional hands.
A garage door that won't open can stem from several sources. The most frequent culprit is a broken spring. Torsion springs support the weight of your door, and when they snap (which happens around 7 to 9 years of normal use), the opener cannot lift the panel. You'll hear a loud bang or pop just before the door stops responding.
Other common reasons include a misaligned safety sensor, a tripped circuit breaker, or an issue with the opener motor itself. Sometimes the problem is simpler: a stuck latch or obstruction blocking the tracks. Weather on Mercer Island also plays a role. Moisture and salt air can corrode metal components, cause tracks to bind, and make rollers stick over time.
Modern garage doors have two infrared sensors near the floor on each side of the opening. If one is blocked, misaligned, or dirty, the door refuses to close (and often won't open either). Dust, spider webs, or even a light knock can throw them off. Clean the lenses gently with a soft cloth and check that both sensors face each other squarely. Most homeowners can do this in under five minutes.
Start with the basics. Press the wall button and listen carefully. Does the opener hum but the door doesn't move? That points to a spring problem. If you hear nothing, check the circuit breaker and make sure the unit is plugged in. Verify the remote batteries aren't dead. Press the button inside your car as well to rule out a door obstruction.
Look at the tracks on both sides. Are they bent, dented, or visibly misaligned? Shine a flashlight along the entire length. Small debris can jam rollers. Gently remove leaves, dirt, or objects. Never force the door manually if springs are involved; a broken spring means the door is under no tension, and you risk serious injury.
If sensors are the problem, cleaning them often works. However, if the door still won't budge after these checks, a spring or opener component is likely broken. This is where professional help becomes necessary.

Do not attempt to replace or adjust torsion springs yourself. They are under extreme tension (roughly 200 pounds of force per spring) and can cause serious injury or death if mishandled. A qualified technician has the tools, training, and insurance to do this safely.

A garage door that won't open traps your car inside. A garage door that won't close leaves your home vulnerable. Both situations deserve urgent attention. We service Mercer Island and surrounding neighborhoods with emergency garage door repair, and we prioritize calls where safety is at risk.
Most stuck doors are preventable with routine maintenance. Check your springs, rollers, and tracks twice a year. Lubricate metal parts with a silicone-based spray (never WD-40, which attracts dust).

Q: Can I force my garage door open if the spring is broken? A: No. A broken spring removes the counterbalance that makes manual lifting safe. Forcing it risks dropping the heavy door on your car or body. Call a professional immediately instead.
Q: How much does garage door repair cost on Mercer Island? A: Repair costs vary. Sensor cleaning is often free. Spring replacement typically costs $200 to $400. Opener repair runs $150 to $300. We provide a free estimate before any work begins.
Q: Why won't my garage door open even though the opener works? A: If the opener motor runs but the door doesn't move, a broken spring is the most likely cause. Other possibilities include a bent track or a disengaged opener carriage. A technician must inspect to confirm.
Q: Is it normal for my garage door to get stuck in winter? A: Cold weather can stiffen lubricants and slow moving parts, but a properly maintained door should still operate smoothly. If it's sticking, tracks or rollers may need cleaning and fresh lubrication.
Q: Should I replace my garage door if it won't open? A: Almost never. Repair is almost always the right first step. A stuck door is usually a fixable component issue, not a reason to buy a new door. We'll guide you on repair versus replacement if major damage is present.
