My garage door safety sensors keep blocking the door from closing. How do I know if they just need realignment?

Safety sensors misalign more often than you'd think, especially after a winter like ours in Greenwich when frost heaves can shift door frames slightly. Start by checking if the sensor eyes are clean and facing each other directly—dust and cobwebs are common culprits. If they're aligned but still malfunctioning, the sensors themselves may be failing. We can test them and realign or replace as needed, usually the same day.

How do I know when my garage door cables are about to fail?

Cables typically last 7–10 years depending on use. Warning signs include visible fraying, a sagging door on one side, or hearing a loud snap when operating. Don't ignore these—a snapped cable won't injure you, but it puts dangerous stress on the springs and opener. If you notice wear, call us for an inspection. Replacing cables before they break is always safer and cheaper than emergency repairs.

Can I reprogram my garage door remote and keypad myself?

Most remotes and keypads can be reprogrammed following your opener's manual, though the steps vary by brand. If you've lost the manual or inherited an older system, we're happy to handle it quickly. Reprrogramming usually takes under 30 minutes and costs far less than replacing hardware. We can also add or remove remotes if family members move away or you need extras.

Is it worth upgrading to a smart garage door opener like MyQ or HomeLink?

Smart openers are genuinely convenient—you can check if your door is open from anywhere or give temporary access to service providers. Most modern openers support MyQ or similar systems at reasonable cost. If your current opener works well, retrofitting a smart controller might make sense. If you're due for replacement anyway, building smart capability in from the start is a smart investment for Greenwich homes.

When should I replace weather stripping and door seals?

Weather stripping around your door frame wears down over 3–5 years, especially on the bottom seal where it takes the most abuse. Greenwich's wet winters and temperature swings accelerate deterioration. Signs include drafts, water pooling in the garage, or visible cracks in the rubber. Replacing seals is affordable and saves energy costs. We often combine this with a spring or cable service visit.

My new garage door feels heavy. Did the installer pick the right opener horsepower?

Opener sizing depends on door weight, insulation, and spring condition. An undersized opener works harder and wears out faster; an oversized one is wasteful. Standard residential openers range from 1/2 to 1 HP. If your door moves slowly, struggles on cold mornings, or the opener cycles frequently, the sizing may be off. We can evaluate your setup and recommend an upgrade if needed.

My garage door came off the track. Is this something I can fix myself?

Off-track doors are dangerous—the door can fall, and misaligned rollers can damage the tracks further. Don't attempt DIY repairs. We handle off-track emergencies regularly and can usually get your door back on and functioning safely within hours. The underlying cause—worn rollers, bent tracks, or spring imbalance—needs proper diagnosis to prevent it happening again.

Do you offer same-day emergency repair if my door gets stuck?

Yes. We keep same-day slots open for genuine emergencies like broken springs or stuck doors. Response time depends on our current schedule and your location in Greenwich, but we prioritize urgent calls. For fastest service, contact us as soon as you notice a problem—don't try forcing the door open, as that often makes repairs costlier.

What's the difference between torsion and extension springs, and which is better?

Torsion springs (mounted above the door) are more durable, safer, and last 15,000–20,000 cycles; extension springs (on the sides) are cheaper but last fewer cycles and pose higher injury risk if they snap. Most modern Greenwich homes use torsion springs for good reason. If you have extensions and they're aging, upgrading to torsion is worth the investment for safety and longevity.

5 Signs Your Garage Door Spring Needs Replacement

# 5 Signs Your Garage Door Spring Needs Replacement

Garage door springs are the unsung heroes of your garage door system. They do the heavy lifting, literally, counterbalancing the weight of the door so your opener can move it with minimal effort. But springs don't last forever, and knowing when they need replacement can save you from being stuck with a door that won't open.

Understanding Garage Door Springs

Before we dive into the warning signs, let's understand the two types of springs:

Torsion Springs: Mounted horizontally above the door opening, these springs twist and unwind to raise and lower the door. They're more durable and provide smoother operation.

Extension Springs: Located on either side of the door along the horizontal tracks, these springs stretch and contract. They're less expensive but have a shorter lifespan.

Sign #1: The Door Won't Stay Open

If your garage door won't stay open when you manually lift it to the halfway point, your springs may be weakening. A properly functioning spring system should hold the door at any point along its travel. When springs lose tension, the door becomes "heavy" and wants to fall.

Sign #2: The Door Opens Unevenly

Does one side of your door rise faster than the other? This is often a sign that one spring is weaker than its partner. Extension spring systems are particularly prone to this issue. Left unchecked, uneven operation can damage your tracks, rollers, and even the door itself.

Sign #3: Loud Bang from the Garage

If you heard a loud bang coming from your garage (similar to a car backfiring), there's a good chance a spring broke. Torsion springs especially can make a startling noise when they snap. After hearing this sound, you'll likely find that your door won't open or feels extremely heavy.

Sign #4: Visible Gaps in the Spring

Take a look at your springs. A healthy torsion spring should be a continuous coil with no gaps. If you see a visible gap, typically 2-3 inches, in the spring coils, it has broken and needs immediate replacement. Never attempt to operate a door with a broken spring.

Sign #5: The Door Falls Quickly When Closing

Does your door close faster than normal or slam shut? This indicates your springs aren't providing adequate resistance. This is dangerous, a rapidly closing door can cause serious injury or damage. If you notice this, stop using the door and call a professional immediately.

Why Professional Replacement Is Essential

Garage door springs are under extreme tension, a single torsion spring can have 200+ pounds of force. Attempting DIY spring replacement has caused serious injuries and even deaths. Always hire a qualified technician who has:

- Proper training and tools, Experience with your spring type, Insurance coverage, Quality replacement parts

How Long Do Springs Last?

Most springs are rated for 10,000 cycles (one cycle = one open and one close). For a typical family using the door 3-4 times daily, that's about 7-10 years. However, factors like climate, maintenance, and usage patterns affect lifespan.

Upgrade to High-Cycle Springs

When replacing springs, consider upgrading to high-cycle springs rated for 25,000 or even 50,000 cycles. While they cost more upfront, they last 2-5 times longer, making them more economical in the long run.

Conclusion

Don't ignore the warning signs of failing garage door springs. At Garage Door Greenwich, we offer same-day spring replacement with high-cycle springs and a comprehensive warranty. Contact us if you notice any of these warning signs, we'll have your door operating safely in no time.
