What exactly does your warranty cover on a new garage door installation?

Our warranty typically covers the door panel itself for 10 years against manufacturing defects, springs and hardware for 5 years, and labor for 1 year from installation. Weather seals and weatherstripping are covered for 3 years. Damage from extreme weather events, lack of maintenance, or accidents isn't included. We'll walk you through the specifics when you choose your door—every manufacturer's coverage differs slightly, so it's worth discussing your particular situation upfront.

How can I tell if my garage door springs are actually broken, or if something else is wrong?

A broken spring usually means your door won't open at all, or it crashes down suddenly—that's the giveaway. If your door opens partway and stops, or moves slowly and unevenly, the opener or cables might be the culprit instead. Listen for a loud bang when the door closes; that's often a spring snapping. Don't try to open a door with a broken spring manually—the tension is dangerous. Call us and we'll diagnose it safely.

If my door gets stuck off-track, how quickly can you get here?

For off-track emergencies on Mercer Island, we typically respond within 1–2 hours during business hours. We prioritize these calls because a stuck door blocks your driveway and can pose safety risks. If it happens after hours, we do offer emergency service—response time depends on the time of night, but we'll give you an honest estimate when you call. Getting it back on track usually takes 30–45 minutes once we arrive.

How do I know if my garage door opener is powerful enough for my door?

Opener horsepower should match your door's weight and material. A standard single-car steel door needs a ½ HP opener; heavier wood or double-car doors often require ¾ or 1 HP. If your opener struggles to lift the door, cycles on and off oddly, or barely moves it, it's undersized. We'll measure your door, check its balance, and recommend the right opener—oversizing doesn't hurt and actually extends opener life by reducing strain.

My garage door won't stay closed. Is it worth repairing or should I replace the whole thing?

If the door is 10+ years old and showing multiple issues—dents, rust, worn panels, plus mechanical problems—replacement often makes more sense financially and safety-wise. Newer doors are more insulated and secure. But if your door is structurally sound and just needs new springs, cables, or an opener, repair is absolutely the right move. We'll inspect yours and give you honest advice, not a sales pitch.

Do I need HOA approval before replacing my garage door on Mercer Island?

Many Mercer Island neighborhoods do have HOA guidelines about garage door appearance and size, especially in areas with consistent architectural styles. Some restrict color or material choices. We recommend checking your HOA documents or calling your management company before ordering a new door. If you're unsure, bring us your current door specs and we can help you navigate options that'll likely get approval—we work with local HOAs regularly.

My safety sensors aren't working. Do I need to replace them or just realign them?

Safety sensors often just need realignment—dust, debris, or a slight bump can throw them out of sync. We'll check the alignment and clean the lenses first; that fixes it 60% of the time. If they're physically damaged or old (10+ years), replacement is safer and inexpensive. Misaligned sensors are a real safety hazard, so don't ignore them. We'll test them under load to make sure they're functioning correctly.

How do I reprogram my garage door remote or keypad if it stops working?

First, replace the batteries—that solves most issues. If that doesn't work, your opener likely needs to be reprogrammed. The process varies by opener model; some require holding a button on the opener itself for a few seconds, others need a sequence of key presses on the pad. Your opener manual has instructions, or we can walk you through it over the phone. If the remote is old or physically damaged, a new one runs $30–60 and pairs quickly.

A2Z Garage Doors

In our years serving Mercer Island, we've seen this problem again and again: homeowners don't understand the safety systems protecting their families every time that door comes down. Auto-reverse and photo eye sensors aren't luxury features. They're non-negotiable protection that federal law now requires on every residential garage door. This guide explains how these systems work, why they matter, and what to do if yours isn't functioning properly.

What Is Auto-Reverse, and Why Does It Matter?

Auto-reverse is the mechanism that stops and reverses your garage door if it meets resistance while closing. Think of it as a fail-safe. When you activate the door and it encounters an obstacle.a toy, a pet, a person.the motor detects that resistance and immediately halts the door's descent, then opens it back up.

The system uses a force sensor (or pressure sensor) built into the opener itself. It measures the force required to close the door. If that force exceeds a safe threshold during the closing cycle, the door reverses. This happens in about half a second. No manual intervention needed.

Federal safety standards, enforced under UL 325, mandate that residential garage doors include this feature. It's been required since 1993. If your door doesn't reverse when meeting resistance, it's either malfunctioning or dangerously outdated.

Photo Eye Sensors: The Second Line of Defense

Photo eyes are infrared sensors positioned on both sides of your garage door opening, typically 4 to 6 inches above the ground. They work in pairs: one transmits a beam, the other receives it. If anything breaks that beam while the door is closing, the door stops and reverses.

Why place them so low? Child safety. A small child crawling under a closing door would trigger the beam before the door could cause serious harm. Photo eyes catch what auto-reverse might miss, especially in scenarios involving young children who don't understand the danger.

Here's what many homeowners don't realize: photo eyes can fail silently. Dirt, spider webs, condensation, or misalignment can block the beam without you noticing. A door that closes smoothly might have non-functioning photo eyes. That's a critical safety gap.

Testing Your Safety Systems (You Can Do This)

Before calling a professional, perform a simple test. Close your garage door normally. Once it's about halfway down, place a rigid object (like a 2x4 block of wood) in its path. The door should stop and reverse immediately when it makes contact. Never use your hand or body for this test.

For photo eyes, wave your hand slowly across the sensor beam while the door is closing. It should stop and reverse. If either test fails, your safety systems aren't working. That's when you need professional attention right away.

Many Mercer Island homes built before 2000 may have doors without functional photo eyes or with aging auto-reverse systems. If you're unsure when your door was installed, a quick inspection can identify potential hazards. Check our guide on garage door maintenance in Mercer Island for routine inspection intervals.

Why Professional Testing Matters More Than You Think

Self-testing catches obvious failures, but it doesn't catch everything. A technician uses specialized equipment to measure force sensors, verify beam alignment, and test response times. They also inspect the mechanical components of the auto-reverse system and ensure your opener's logic board is functioning correctly.

We've discovered non-functioning photo eyes and miscalibrated force sensors on hundreds of Mercer Island doors that appeared to work fine. The homeowners had no idea they were running a safety risk every single day. Professional testing takes about 15 minutes and costs far less than dealing with an injury.

If your door opener is more than 15 years old, the force sensor calibration may have drifted. Older openers from the 1990s and early 2000s sometimes fail without warning. If you're planning a replacement, explore our complete guide to garage door openers for Mercer Island homes to understand your options.

Child Safety Beyond Auto-Reverse and Photo Eyes

Auto-reverse and photo eyes are baseline protections, but they don't eliminate all risks. Children can still be injured if they crawl under a descending door or get fingers caught in the door panels. Supervision and education matter just as much as technology.

Teach children that the garage door is not a toy. Don't let them play near the door or remote control. Install your remote where children can't access it. Consider a smart opener that requires authentication, adding another layer of child safety. See our smart garage door technology post for Mercer Island for modern safety options.

What to Do If Your Safety Systems Aren't Working

If your auto-reverse or photo eyes aren't functioning, contact a professional immediately. Don't keep using the door. Temporary fixes or workarounds aren't safe. A technician can typically repair or replace these systems on the same day, depending on the damage.

Repair costs vary based on what's broken, but most auto-reverse or photo eye repairs fall within a reasonable range. Get a free estimate before work begins.

Frequently Asked Questions

How often should I test my auto-reverse and photo eyes? Test them monthly. It takes two minutes and catches degradation early. Professional inspection annually is also recommended to catch subtle sensor drift or alignment issues that visual tests miss.

Can I replace photo eyes myself? Possibly, if you're comfortable with basic wiring. However, alignment is critical for proper function. Even a slight angle can cause false triggers or missed obstructions. Professional installation ensures correct positioning and connection to your opener's logic board.

What if my door reverses too easily? A hypersensitive auto-reverse can indicate improper force calibration. This sometimes happens after repair work or opener adjustments. It needs professional recalibration. Don't adjust it yourself, as this can compromise safety.

Are photo eyes required by law in Washington state? Yes. Federal UL 325 standards, adopted in Washington, mandate photo eyes on all residential garage doors manufactured after 1993. Older doors without them should be retrofitted for safety compliance.

How much does it cost to repair or replace safety sensors? Photo eye replacement typically ranges from $150 to $300 per pair, including installation. Auto-reverse sensor repairs or replacements vary from $200 to $500 depending on your opener model. Call for a specific estimate based on your door.
