How do garage door sensors work?

• <div><p>Garage door sensors work by using infrared beams to detect objects in the door’s path. One sensor sends a beam while the other receives it. When the beam is broken—say, by your car or anything else—the sensors signal the door to stop or reverse. It’s all about safety and making sure nothing gets trapped under the door. If they’re misaligned, the beam doesn’t connect, and <a href="https://www.angi.com/articles/how-does-garage-door-opener-work.htm">the garage door might stay open</a> or close regardless of obstructions. </p></div>

Q: Is one or two garage doors better?

• <div><p>Single and double garage doors have pros and cons, but it's all based on personal preference regarding which one is better for you. Two single garage doors give you more control over airflow entering your garage but double the system, which means double the upkeep cost. </p><p>On the other hand, two-car double garage doors are more convenient but can stop you from leaving if a piece of hardware malfunctions.</p></div>

Q: Is it safe to install a pet door on my garage door?

• <div><p>It&rsquo;s <a href="https://www.angi.com/articles/are-pet-doors-your-garage-door-safe.htm">not safe to install a pet door on your garage door</a>. Garage doors that tilt upward can roll up with your dog inside the door without you realizing it, making them dangerous and potentially deadly. Most dog doors also won&rsquo;t fit on traditional garage doors, as they would need to span the panels, compromising the door&rsquo;s stability.</p></div>

Q: Will a 20x20 garage fit 2 cars?

• <div><p>The smallest size a standard 2-car garage can be is 20 feet by 20 feet, so at these dimensions, you could reasonably expect to fit two cars inside. However, it&rsquo;s going to be a tight fit, especially if you have larger SUVs or pickup trucks. For smaller cars, 20 x 20 should be plenty for parking and some space to maneuver around the cars. A larger garage size would be better to ensure you have room to open the doors and transport groceries or other items around the cars.</p></div>

Q: Why do my garage door cables keep coming off?

• <div><p>There are several reasons garage door cables can come off multiple times. The most common reason is that the springs have too much or too little tension and require adjusting. Other causes include track alignment issues that keep the door from operating correctly or smoothly. A damaged winding drum or obstructions in the cable's way can also cause it to come loose. </p></div>

I called in to ask for service. They had a technician out early the next morning. He didn’t have the part at the time but returned when he did. The office staff and technician were very helpful and professional. I’ll certainly be using them for all future garage door needs.

Had them do two jobs in the past 2 months. Excellent on both. Installed a smart door lock and fixed a nuisance screen door in one trip, later came back and installed new drainage pipe. Always available, very flexible, and patient. And of course the work is top-notch.

Excellent! Our house was built 50 years ago and this company built the new garage with a style and materials that made the new construction look as if it had been built when the house was. They took time to build a quality structure with no short cuts. We are VERY pleased!
