Garage Door Spring Replacement and Two-Spring Conversion in Greenwood Village, CO

Replacing a Broken Garage Door Spring in Greenwood Village

A broken torsion spring is one of the most common reasons a garage door stops working. On this recent job in Greenwood Village, our team replaced a broken spring on a 16×7 vinyl-backed garage door. The door had been running on a single spring, so rather than install a one-for-one replacement, we converted the system to a two-spring setup.

The conversion spreads the door’s weight across two springs instead of one, which helps with long-term reliability and adds a margin of safety the original setup did not have.

What Do Garage Door Torsion Springs Do?

Torsion springs counterbalance the weight of the garage door. They are mounted on a shaft above the door opening and store tension as the door closes, then release it to help lift the door as it opens. The opener or the person lifting the door is only handling a small fraction of the actual weight.

A 16×7 double-car door is heavy, and the springs do the bulk of the work on every cycle. When a spring breaks, the door may refuse to open, open only a few inches, or feel far heavier than normal. Our garage door services include spring repair and replacement for residential doors of all sizes.

Spring Replacement and Conversion on This Greenwood Village Job

For this project, we removed the broken single spring and installed two new torsion springs sized for the door’s weight and height. The system was then adjusted and balanced so the door travels smoothly and stays in position when stopped partway.

Converting from one spring to two offers two main advantages:

• Longer cycle life. With the load shared between two springs, each spring carries less of the door’s weight. Less strain per spring typically means a longer service life and fewer unexpected breakdowns.
• Greater safety. If one spring in a two-spring system breaks, the other still holds part of the door’s weight. The door is less likely to drop suddenly, and it stays more controlled until the broken spring is replaced.

A single-spring system has no backup. When that one spring fails, the full weight of the door is left unsupported.

Signs Your Garage Door Spring Needs Attention

Spring problems often show up before the spring fully fails. Common signs include:

• A visible gap in the coils of a torsion spring.
• A loud bang from the garage when no one was using the door.
• The door opens only a few inches before stopping.
• The door feels unusually heavy when lifted by hand.
• The door closes too quickly or will not stay in place when partially open.

Some of these symptoms can also come from cable or opener issues, so an inspection helps confirm which component needs repair.

Is a Two-Spring System Better Than a Single Spring?

For most double-car doors, a two-spring system is the better long-term choice. Single-spring setups are common on builder-grade installations because they cost less up front, but that one spring is doing all the work on every open and close.

Two springs share the load, which reduces wear on each spring and adds redundancy if one breaks. When a spring replacement is already needed, converting to two springs is a practical time to make the upgrade, since the door is already being worked on.

Frequently Asked Questions About Garage Door Springs

Can a single-spring garage door be converted to two springs?

Yes, in many cases. The existing shaft and hardware are evaluated, and new springs are sized to match the door’s weight and height. On this Greenwood Village job, we converted a 16×7 door from one spring to two during the replacement.

Why do two springs last longer than one?

Each spring in a two-spring system carries part of the door’s weight rather than all of it. Reduced strain on each spring generally leads to a longer cycle life.

If one spring breaks on a two-spring door, should both be replaced?

Replacing both is usually recommended. The springs were installed together and have gone through the same number of cycles, so the remaining spring is often close to the end of its life as well.

How much does garage door spring replacement cost?

Pricing depends on the door’s size and weight, the type of springs needed, and whether a conversion or other hardware work is involved. Contact Harmony Garage Door Repair Denver to discuss your door and arrange an inspection.
