A quick Bow homeowner self-inspection can spot wear before it becomes dangerous. Follow these safe steps, know the warning signs, and stop before anything risky—we’ll tell you exactly when to call us.
Gather your tools and prep the door
Park your car clear of the door and unplug the opener. Grab a flashlight, a tape measure, and a notepad. Stand back and note any visible gaps, rust, or uneven gaps between the door and frame. Bow’s freeze-thaw cycles can loosen hardware—check the hinges and rollers now. Never stand under the door while it’s moving. If you see frayed cables or a door that sags when closed, stop and call a pro immediately. blog/broken-garage-door-spring-replacement-bow-nh-safety-costs. Learn more about our full list of services.
Test the balance and travel safely
Disconnect the opener by pulling the release cord. Lift the door halfway by hand—it should stay put. If it drifts up or down, the springs are unbalanced and unsafe to adjust yourself. Next, lower the door fully and check that it seals evenly against the floor. Bow’s humidity can warp wood doors, so look for uneven gaps. Never force a door that sticks; forced travel can damage tracks or injure you. If the door jerks or makes grinding noises, stop and call us before the next use.

Inspect cables, springs, and hardware
Stand clear and visually inspect the lift cables for fraying or kinks. Check the springs for rust, gaps, or uneven spacing—Bow’s salty winter roads accelerate corrosion. Tighten loose hinges and brackets with a socket wrench, but never touch the springs or cables. If a spring is broken or the door feels heavy after disconnecting the opener, do not operate it. services covers spring and cable replacement safely. Leave adjustments to certified techs to protect your warranty and safety. Explore about our team and credentials.
Check sensors and auto-reverse safety
With the opener plugged in, close the door and wave a broomstick in its path mid-travel. The door should stop and reverse within two seconds. If it doesn’t, the sensors are misaligned or dirty—clean the lenses with a soft cloth. Bow’s bright sunlight can blind sensors, so check alignment monthly. Never bypass sensors to test travel speed; this violates safety codes and risks injury. If the door still won’t reverse, schedule a sensor calibration visit with us. For details, see the areas we serve.
Warning signs that mean stop and call a pro
Stop immediately if you see broken springs, frayed cables, or a door that’s off its tracks. Loud grinding, popping, or a door that jerks during travel are red flags. Rust on springs or hinges, gaps wider than a credit card, or a door that won’t stay open or closed also require a pro. Bow’s older homes often have mismatched or worn hardware—don’t gamble with DIY fixes. blog/off-track-garage-door-repair-bow-nh.

Frequently Asked Questions
Why does my Bow garage door make a grinding noise when opening and is it safe to ignore?
A grinding noise usually means dry or worn rollers, a misaligned track, or failing hinges. Bow’s humidity and road salt accelerate wear, so it’s not just noise—it’s a sign of impending failure. Ignoring it risks track damage or a sudden cable snap. Schedule a roller and track inspection with us before the next use.
My Bow garage door opener reverses when I press the button but won’t close—what’s wrong?
This is often a sensor or travel-limit issue. Bow’s bright sunlight can blind sensors, or a misaligned track can trigger the auto-reverse. Check sensor alignment and clean the lenses first. If the problem persists, the travel limits may need recalibration—leave this to a pro to avoid damage or injury.
How can I tell if my Bow garage door springs are about to fail before they break?
Look for rust streaks, gaps in the coils, or a door that feels heavy when lifted manually. Bow’s freeze-thaw cycles stress springs faster. If you see any of these signs, stop using the door and call us. blog/broken-garage-door-spring-replacement-bow-nh-safety-costs.
