Garage door questions from Arlington Heights homeowners

Anyone pinned or hurt under a door is 911 first. After that, an open door, a car trapped inside, or a spring that has just let go all count. Cars have to be kept out from under the door, nobody should try to lift it by hand, and if the door is up or hanging, switch off the garage breaker at the panel. If the door will not close, that is urgent help for a door stuck open.

No, not by hand and not with the opener. A closed door with a snapped torsion spring is holding all of its own weight, and an opener is not sized to lift that on its own. Leave the door closed, park the car on the driveway, and call. The fix is a proper spring replacement with the right matched pair.

Most of the time it is the two safety sensors near the floor. Check the little lights on both boxes. If one is off or flashing, the sensors are out of line, blocked by a leaf, or hit by a low winter sun. Wipe the lenses, sight down the beam, and try again. If the sensors look fine and the door still reverses, the travel limit or force setting has drifted, which is opener repair territory.

Work through the easy things first: power at the outlet, the lock button on the wall control, and the safety sensors near the floor. When the opener motor runs but the chain does not pull the door, the trolley has usually come off the carriage. When the opener strains, stops and gives up, the door itself may have gotten heavy from a broken spring. A longer list sits at the checks in order for a door that stops.

This is one job to leave alone. A wound torsion spring stores enough energy to break a wrist, and the setup bars, winding cones and matched replacement springs have to be sized and handled with practice. People who can do their own brakes and drywall skip this one. If a spring has snapped, keep the door closed, keep hands off, and let a technician set a matched pair. See broken spring repair for what the visit involves.

Springs are rated in cycles, not calendar time, and one cycle counts one open and one close together. A standard pair on a family door lasts a good while. A house where the garage is the front door burns through cycles faster than one where the family walks in from the front porch. More in winter and garage door springs.

Cold on its own does not snap a healthy spring or crack a healthy panel. Northern Illinois averages about 140 days a year at or below 32 degrees, and 16 at or below 0.¹ What the yearly tune-up looks at is the parts around the spring: hinges, rollers, cables, tracks and the opener's safety tests. The spring coils themselves and the balance check are the technician's part of that visit.

If the opener is old enough to lack the two safety sensors near the floor, replace it. Modern openers have photo eyes down low and reverse before touching anything underneath, and a door without those is not safe around children or pets. On a newer opener, most failures like sensors, gears, boards and remotes are repairs. If yours is a borderline case, the common opener trouble page covers what is worth fixing and what points to a new unit.

Look on the back of the opener head for a small button labeled Learn. Press it, and within about half a minute press the new remote's button. The opener's light should blink or the button should click, and the remote is paired. Older units and different brands put that button in different places. If you cannot find it or the pairing fails, call and leave the brand and model number from the opener head in your message.

A real price needs a look at the door. What moves the number is which part failed, its grade, whether both sides of a pair get done at once, the door size, and whether a given company charges differently outside normal hours. Illinois law requires a written contract or work order for larger home repair jobs,² which is where the numbers should land. What actually sets a repair price walks through each driver.

Two companies quoting the same door can price different jobs on paper. One quote might cover only the broken spring; the other might pair the springs, swap worn cables and finish with a balance test. Part grades vary too. The longer breakdown of what sets a repair price walks through each piece.

On one failure on an otherwise sound door, a repair covers less than a new door: a single spring, a set of rollers, a control board, a cable. That flips when several panels have gone, when the model has been retired for years, or when parts for the door have become hard to find. Weighing a repair against a new door walks through the trade.

Depends on the job. On routine work the Village's residential permit list has no separate guide for garage doors; questions go to Building and Life Safety.³ On emergency work the rule is clear: the Village requires a permit for all emergency repair work, submitted within 24 hours after the work begins.³ Ask Building and Life Safety whether your specific job needs a permit before any crew touches the opening. More at what the village publishes about permits.

Two quick tests before anyone comes out. First, pull up the village's contractor list that Building and Life Safety publishes;⁴ the list is dated, so a call to Building and Life Safety confirms whether a company is registered for the current year. Second, ask for the price before any work starts, in writing on larger jobs as Illinois law requires a written contract or work order.² A price given only over the phone with no visit is a soft answer. How to check any company before they come out has the longer checklist.

Not in Illinois. State law bars a home repair contractor from advertising or promising to pay or rebate any part of a customer's insurance deductible² in order to land the job. A company that offers to eat the deductible on a storm claim is asking you to help them break state law; say no and move on. The checklist for hiring covers a few more of these.

Tell us about the door: what it is doing right now, where it stopped, the opener brand, and whether a car is inside the garage. We get back to you about the door and when we can be out to look at it. Our number and hours live on the contact page.

Four things speed the call up. One, the door type: single wide, double wide, or two singles side by side. Two, what happened: a bang, a slow slide, a stop halfway, or a scrape at one spot. Three, the opener brand and roughly how old it is (labels sit on the side of the opener head). Four, where the door stopped if it stopped there. If a car is stuck inside, say that on the call.

Tell us if the door is stuck open or a car is trapped, because that changes what we handle first.

We work on garage doors across Arlington Heights. Read the address to us when you call. There is more on the village's housing on the area page.

Call (847) 440-3650. Tell us the noise you heard, the spot the door stopped at, and whether a car is trapped inside. If the door is stuck open, keep people and vehicles clear of the opening before you dial.
