How much energy does a torsion spring actually hold?

Enough to lift a door weighing a couple of hundred pounds, released through a cone about the size of your fist. That is the reason the tooling is specific rather than improvised.

Can I use a screwdriver instead of winding bars?

No. A screwdriver in a winding cone gives an unstable grip on a component under full tension, and it is the single most common thing we find on these calls.

I bought a spring that looks identical. Is that enough?

Diameter alone does not specify a spring. Wire gauge, inside diameter, length and the door's measured weight all have to match, and a lookalike can be rated for a much lighter door.

What if I have already started?

Stop, leave the door and the spring where they are, and call. Unwinding a partly wound spring safely is routine for us and it is not a call we make anyone feel bad about.

Is extension spring work any safer?

It is different, not safe. Extension springs stretch under load and become projectiles when they fail, which is what containment cables are for. If yours do not have them, that is worth fixing.

What can I do myself?

Keep the beam path clear, clean the track, lubricate hinges and rollers, and check the balance by hand. That covers most of what keeps a door healthy between service visits.

Why DIY Spring Repair Is Dangerous

The energy is the whole problem

A wound torsion spring holds the energy that lifts the door. Winding bars are steel rods inserted into the winding cone to add or release that tension under control, and they exist because the alternative is releasing it all at once.

The substitutions we find are a screwdriver, a length of rebar, a bolt. Each one gives an unstable grip on a component under full tension, and a grip that slips does not give you a second chance to reconsider.

The video makes it look manageable because the person filming it has done it before, with the right bars, on a spring they measured. That is the part that got edited out. Spring work runs under garage door repair in Windermere, and you can verify it with the Florida DBPR for whoever you hire.

The spring you ordered is probably wrong

Almost every DIY call starts the same way: the replacement was ordered on the diameter of the old one. Diameter alone does not specify a spring.

The match is on wire gauge, inside diameter, length and the door's actual measured weight. A spring that looks identical to the one that broke can be rated for a door sixty pounds lighter than yours, and it will feel fine on the day and fail early.

That is also why the door gets weighed rather than estimated. Spring cycle ratings are measured to the test methods published by DASMA, the industry standards body, and a rating means nothing if the spring was matched to the wrong door.

What we typically find on these calls

The pattern is consistent enough to describe before pulling into the driveway.

A spring matched on diameter alone, wrong on gauge or length
Improvised winding tools instead of proper bars
One spring replaced on a two-spring door
Cables left off the drums or wound unevenly
The door never weighed, so tension is guesswork
Safety devices disconnected to test the door

There is no judgement in this list. It is what the job actually requires, and none of it is obvious from a video.

What is safe to do yourself

Plenty of garage door maintenance is homeowner work. This is where the line sits.

Reasonable to do

No stored energy involved.

Clearing the photo eye beam path and wiping lenses
Cleaning the track, without lubricating it
Lubricating hinges and rollers with the right product
Checking the balance by hand with the opener released
Replacing a bottom seal on a sound retainer

Leave alone

Stored energy, or the door's load path.

Anything involving winding or unwinding a spring
Cables, drums and bottom brackets
Lifting a door that is off its track
Bending a track section back
Bypassing a safety sensor to make a door close

If you have already started and the spring is partly wound, that is a call we take at any hour rather than a lecture.
