Why won't my garage door close?

Common reasons include: misaligned safety sensors, obstructions in the door path, broken springs, stripped gears in the opener, or issues with the close limit settings. Check the safety sensors first - they should both have steady lights.

Should I repair or replace my garage door?

Consider replacing if: the door is over 15-20 years old, has significant rust or structural damage, panels are severely damaged, or you want to upgrade to an insulated door. Many issues like springs, cables, sensors, and openers are cost-effective to repair.

What do the blinking lights on my garage door opener mean?

Blinking lights indicate error codes. For LiftMaster/Chamberlain: 1 blink = sensor wire issue, 2 blinks = sensor wire short, 3 blinks = door control wire issue, 4 blinks = sensor misalignment, 5 blinks = motor issue. Use our error code lookup tool for specific diagnosis.

How do I calculate what torsion spring I need?

To calculate the correct torsion spring, you need: door height, door width, door weight, track type, and number of springs. The formula involves IPPT (Inch-Pounds Per Turn) = d^4 × E / (10.8 × D × Na). Use our spring calculator for accurate results.

Can I replace a garage door spring myself?

Torsion spring replacement is dangerous and recommended only for trained professionals due to the extreme tension (over 200 lbs of force). Extension springs are safer for DIY but still require proper safety precautions and tools.

Garage Door Panel Damaged

Some Experience Needed2-4 hours (professional)

A damaged garage door panel can sometimes be repaired for minor dents, but significant damage usually requires panel replacement or a new door. Single panels can often be replaced if your model is still available. Older doors may require full replacement.

Common Symptoms

Visible dent or bend in panel
Cracked or split panel
Panel pushed in or out of alignment
Door doesn't close evenly
Gap or light showing through damage

Possible Causes

•Vehicle impact (most common)
•Sports equipment (basketballs, etc.)
•Hail or wind damage
•Break-in attempt
•Age and material fatigue
•Tree limb or falling object

How to Fix It

Assess the damage severity

Is it a surface dent, a crease, or a puncture? Does the door still operate? Minor dents may be cosmetic only.

Check door operation

Open and close the door to see if damage affects function. Listen for binding or scraping.

Identify your door make and model

Find the manufacturer sticker (usually inside edge of door). Note the model number—you'll need this if ordering a panel.

For small dents

Try a dent puller or push from behind. Heat the area with a heat gun to make metal more pliable. Auto body filler can smooth small imperfections.

Get a panel replacement quote

Contact your door manufacturer or a local garage door company. Provide the model number and panel position (1st, 2nd, etc. from bottom).

Compare to new door cost

If the panel costs more than 40-50% of a new door, or if your door is old with discontinued panels, replacement may be better value.

When to Call a Professional

•Damage affects door operation or safety
•Panel replacement is needed
•Multiple panels are damaged
•Door structure is compromised
•You're unsure if it's safe to operate

Frequently Asked Questions

Can I replace just one panel?

Usually yes, if the panel is still manufactured and the rest of the door is in good condition. Older doors may have discontinued panels, forcing full replacement.

How long does it take to get a replacement panel?

Stock colors typically 1-2 weeks. Custom colors or less common models can take 4-6 weeks. Some manufacturers have discontinued older models.

Will insurance cover the damage?

Often yes, depending on how it happened. Vehicle damage is usually covered under auto insurance. Storm damage falls under homeowner's insurance. File a claim if repair costs exceed your deductible.
