Garage Door FAQ — American Garage Doors Repair Service
Garage Door FAQ
Answers to the most common garage door questions from the team at American Garage Doors Repair Service in Livingston, NJ.
Springs & Cables
How long do garage door springs last?
Standard residential springs are rated for approximately 10,000 cycles — roughly 7–10 years with typical daily use. High-cycle springs rated for 25,000 or 50,000 cycles are available and are often worth the upgrade for heavier-use doors.
What causes garage door springs to break?
Springs break primarily from metal fatigue after thousands of open/close cycles. Contributing factors include lack of lubrication, rust and corrosion, extreme temperature swings, and an imbalanced door putting extra stress on the springs.
Can I replace garage door springs myself?
We strongly advise against DIY spring replacement. Torsion springs store significant energy under tension — releasing them incorrectly can cause severe injury. This is one repair best left to trained professionals with the right tools.
Should I replace both springs at once even if only one broke?
Yes. Both springs experience the same wear. If one broke, the other is likely near the end of its life. Replacing both now saves a second service call, keeps the door balanced, and is typically only marginally more expensive.
What's the difference between torsion and extension springs?
Torsion springs mount horizontally above the door opening and twist to create lifting force. Extension springs run along the upper side tracks and stretch. Torsion springs last longer, are safer, and are standard on most modern doors. Extension springs are common on older homes and lower-clearance garages.
Is it safe to use my garage door if a cable is broken or frayed?
No. A broken cable means the door is unbalanced and could fall unexpectedly or come off the tracks. Stop using the door immediately and call for service — attempting to operate it can cause additional damage or injury.
Openers & Motors
How long does a garage door opener last?
Most garage door openers last 10–15 years with average use. Heavy-use applications or commercial settings may see shorter lifespans. Regular maintenance extends opener life significantly.
Why won't my garage door opener respond to the remote?
Start with the simple fix: replace the remote batteries. If that doesn't help, check that the wall button works. If the wall button works but the remote doesn't, you may need to reprogram or replace the remote. If neither works, the issue is likely with the opener itself.
Why does my garage door reverse before fully closing?
The most common cause is misaligned or obstructed photo-eye sensors. These are a safety feature — if the infrared beam is interrupted or the sensors aren't pointing at each other, the door reverses. Clean the sensor lenses and check alignment. If that doesn't solve it, the down-force limit may need adjustment.
My opener hums but the door doesn't move — what's wrong?
This is a classic sign of a stripped drive gear. The motor is running, but the plastic gear that drives the trolley is worn out and not engaging. Gear replacement is usually economical for openers under 10 years old.
What drive type is quietest for a garage door opener?
Belt-drive openers are the quietest. Direct-drive openers (single moving part — the motor moves along the rail) are also very quiet. Chain-drive openers are the most economical but significantly louder — not ideal if there's living space above or beside the garage.
Can I add smartphone control to my existing garage door opener?
Sometimes. If your opener has a compatible terminal, add-on Wi-Fi accessories from brands like myQ can add smart control. Alternatively, upgrading to a new opener with built-in Wi-Fi is often more reliable. We can assess your current opener during a service call.
Installation & Replacement
How long does garage door installation take?
A standard single-car door installation typically takes 2–4 hours. Double doors take 3–5 hours. Custom or unusual installations may take longer. We'll give you a realistic time estimate when scheduling.
What type of garage door insulation do I need?
The R-value you need depends on your climate and how you use your garage. For an attached, climate-controlled garage or one with living space above, aim for R-12 to R-18. For a detached garage in a mild climate, a lower R-value or non-insulated door may be sufficient.
How do I choose between steel, wood, aluminum, and composite doors?
Steel offers the best balance of durability, insulation options, and value — it's the most popular choice. Wood is beautiful but requires more maintenance. Aluminum is rust-resistant and lightweight. Composite offers a wood look with much lower maintenance. We'll walk you through the pros and cons for your specific situation.
What are standard garage door sizes?
Single-car doors are most commonly 8×7 or 9×7 feet. Double-car doors are typically 16×7 feet. Heights of 7 and 8 feet are most common. RV and oversized openings require custom or special-order doors.
How long does a new garage door last?
A quality steel garage door with regular maintenance typically lasts 20–30 years. Longevity depends on the material, climate, maintenance history, and quality of original installation.
Should I repair my old door or replace it?
If the door has been repaired multiple times, has significant structural damage, or the cost of repairs approaches 50% of a new door's price, replacement usually makes more sense economically. We'll give you an honest assessment and won't push replacement when repair is the right call.
Maintenance & Performance
How often should I have my garage door professionally serviced?
For most residential doors, once a year is appropriate. Doors used 3 or more times per day, or in commercial applications, benefit from service every 6 months. Annual service typically costs far less than a single emergency repair.
What does a garage door tune-up include?
A full tune-up covers visual inspection of all springs, cables, rollers, and hardware; tightening all hardware; lubrication of rollers, hinges, and springs; balance testing; opener force and travel adjustment; and safety feature verification.
Can I do basic garage door maintenance myself?
Yes — lubricating rollers, hinges, and springs with a garage door lubricant spray (not WD-40) is something homeowners can do. Keep tracks clean and check for loose hardware. Spring adjustment, cable work, and opener calibration should be left to professionals.
Why is my garage door slow or sluggish?
Sluggish operation is usually caused by an out-of-balance door putting extra load on the opener, worn or dry rollers, dirty or obstructed tracks, or an opener that needs its travel force limits adjusted. A tune-up typically resolves this.
How do I test my garage door's auto-reverse safety feature?
Place a flat 2×4 on the floor in the door's path. When the closing door contacts it, it should reverse immediately. If it doesn't reverse, or applies significant pressure before reversing, the door's down-force limit needs professional adjustment.
What lubricant should I use on my garage door?
Use a dedicated garage door lubricant — typically a white lithium grease or silicone spray formulated for this purpose. Avoid WD-40 (it's a solvent, not a lubricant), and don't lubricate the inside faces of the tracks.
Emergency Situations
My garage door won't close — is it a security risk and what should I do?
Yes, an open garage is a security risk. First, try the wall button — if that doesn't work, check the photo-eye sensors for obstructions or misalignment. If those are clear, call for emergency service. In the meantime, lock any interior doors leading from the garage into the home.
My spring broke and my car is inside — what do I do?
You can manually open the door using the emergency release (red cord), but a door without working springs is very heavy — you may need help. Lift from the bottom with both hands and set the door fully open before driving out. Call for spring repair before using the door again.
My door came off the track — can I push it back on myself?
Simple track derailments can sometimes be re-seated, but doing so without understanding the cause can result in injury or make the problem worse. If the door is hanging at an angle or under tension, do not touch it — call for professional service.
What should I do if a car hits my garage door?
Do not operate the door — even if it looks only cosmetically damaged, the tracks or springs may be compromised. Document the damage for insurance. Call us for an inspection before using the door again.
My garage door opened on its own in the middle of the night — why?
This is usually caused by a neighbor's remote on a similar frequency (rare with modern rolling-code technology), a stuck button on a remote or wall button, or a faulty circuit board. We can diagnose and resolve this during a service call.
Is it safe to operate a garage door during a power outage?
Opener-controlled doors won't work during a power outage unless your opener has a battery backup. You can operate the door manually using the emergency release cord. Pull the red cord, then lift the door manually. It will be heavy if the springs are worn or broken.
Cost & Warranty
Do garage door repairs come with a warranty?
We warrant our labor and the parts we install. Warranty periods vary by repair type and part manufacturer — we'll tell you exactly what's covered before we begin work.
What factors affect the cost of garage door repair?
Cost is determined by the type of part needed, the labor time required, the age and brand of your existing door and opener, and whether any additional issues are discovered during the repair. We provide upfront pricing before any work begins.
Does homeowner's insurance cover garage door damage?
It depends on the cause. Damage from a covered peril (storm, vehicle impact, vandalism) is typically covered minus your deductible. Normal wear and tear, spring failure, and mechanical breakdown are generally not covered. Check your specific policy.
What should I look for when choosing a garage door company?
Look for a company that is licensed and insured, has verifiable local reviews, provides written estimates before work begins, employs trained technicians (not day-labor subcontractors), and warranties their work. Be cautious of unusually low advertised prices — they often don't reflect the final bill.
Why do I get wildly different quotes from different companies?
Quotes vary because of differences in parts quality (OEM vs generic), labor rates, warranty coverage, and whether the technician properly diagnosed all issues upfront. The cheapest quote may use lower-quality parts or discover "additional" problems on-site.
Is financing available for a new garage door or major repair?
Ask us about available financing options. Financing can make a full door replacement or major repair more manageable without compromising on quality.
