Your garage door won't open. Before you panic or pay for an emergency call, try these five quick checks. Most Marlborough homeowners discover the problem is something simple, and you might save yourself $100 to $200 in unnecessary service fees.
A garage door that refuses to budge is one of the most frustrating problems homeowners face. The good news: it's rarely catastrophic. In our years serving Marlborough and the surrounding area, we've seen this problem again and again, and about 40 percent of the time, the fix costs nothing.
The issue could be your remote batteries, a misaligned sensor, a tripped circuit breaker, or a broken spring. Some of these you can fix yourself in five minutes. Others need professional hands. Let's walk through what to check before you call.
This sounds obvious, but dead batteries are the number-one culprit. Your garage door remote uses two AA or AAA batteries, and they wear out faster than you'd think, especially if you use the remote multiple times daily.
Replace both batteries at once. Don't just swap one. Then test from a few feet away. If the door opens, you've solved it for under a dollar. If not, try the wall-mounted button inside your garage. Does that work? If yes, your remote is broken. If the wall button also doesn't work, move to the next step.
Your garage door has two photo eye sensors near the bottom of each side of the opening. These infrared sensors detect obstacles and prevent the door from closing on pets, toys, or people. If they're blocked or misaligned, your door won't open or close.
Walk over and check both sensors. Are they dirty? Wipe them gently with a clean cloth. Are they pointed at each other? They should be aligned directly across from one another. If one is knocked sideways, gently adjust it. Many stuck garage doors come down to a sensor that got bumped during a recent storm or by a child's bike.

Walk to your garage breaker panel and look for a tripped breaker. If the handle is in the middle or flipped down, switch it back on. This resets power to your garage door opener.
Next, plug a lamp or phone charger into the outlet where your garage door opener is plugged in. Does the lamp turn on? If not, the outlet is dead. Try resetting that breaker too. A power surge from recent storms can trip breakers, and it's the easiest fix there is.
This is critical. When you press the remote or wall button, do you hear the motor running? If yes, the opener is working but the door isn't moving. This usually means a broken spring. Do not attempt to open the door manually or force it. A broken spring puts 400 pounds of tension on that door, and it's genuinely dangerous.
If you hear nothing at all, the problem is likely electrical. If you hear clicking but no motor hum, the opener itself might be failing. Either way, it's time to call a professional. Springs last 7 to 9 years on average, and if yours has snapped, you'll need a technician. Learn more about what to expect in our guide on garage door springs when one snaps.
Walk around your garage door and look for bent panels, dents, or anything blocking the tracks. Sometimes a storm or accident shifts the door slightly, and it gets stuck. If you see something obviously wrong, don't force it. Forcing a stuck door can cause more damage and cost you hundreds more.
If you've tried all five steps and your door still won't open, it's time to get a free estimate. Don't guess at repairs or try DIY fixes on springs or openers.

What does it mean if my garage door opens halfway then stops? Halfway stops usually signal a broken spring, limit switch issue, or motor problem. The door may feel heavy or unresponsive. Never force it. Call a technician for a safe diagnosis and repair.
Can I open my garage door manually if the opener is broken? Yes, most doors have a red emergency release handle inside the garage. Pull it down to disengage the opener, then you can lift the door by hand. This works as a temporary fix only.
How much does same-day garage door repair cost in Marlborough? Typical repairs range $150 to $500 depending on the part. Springs cost more than sensors or batteries. Call for a free estimate before any work begins.
Why won't my garage door close even though it opens fine? Misaligned sensors are the most common reason. Check that both photo eyes are clean and facing each other. Dirt or a bump can prevent closing without affecting opening.
Should I try to fix a broken spring myself? No. Springs are under extreme tension and extremely dangerous. Always hire a professional. DIY attempts cause serious injury every year.
