Garage Door Spring Replacement in Murfreesboro, TN
A snapped torsion or extension spring leaves the door too heavy to lift and the opener straining. We fit matched springs sized to your door, test the balance and leave the same visit.
Garage door spring replacement in Murfreesboro, TN is a same-visit repair in most cases: we size the spring to the door, fit it, wind it, and balance the door before we leave. Most calls take 30 to 60 minutes on site once we arrive. A pair of torsion springs on a standard door runs $150 to $350 installed, and we quote the exact figure after we measure the door, as of 2026.
The spring carries the weight; the opener only guides the door. When one breaks, the door feels like dead weight, the opener strains or stops a few inches up, and you should stop using it. Do not try to lift a double door by hand with a broken spring. If you are not sure which type you have, see torsion versus extension springs.

What Our Spring Replacement Work Covers
Broken torsion springs
The spring above the door with a clean gap in the coil. We replace both springs on a two-spring door.
Broken or stretched extension springs
The springs beside the horizontal tracks. We replace them as a pair and fit or check the safety cables that run through them.
Springs and cables together
A broken spring often takes a lift cable with it, or the cable jumps the drum when the tension goes slack. We check both drums and both cables on every spring call.
Torsion or Extension: Which Spring Is on Your Door
Torsion springs
A torsion spring sits on a steel shaft above the door opening and lifts by twisting. Torsion springs last 7 to 15 years, or 10,000 to 20,000 cycles. Most doors in Murfreesboro built after 2000 have them, and more than half of the city housing stock dates from 2000 or later.
Extension springs
An extension spring runs alongside each horizontal track and lifts by stretching. Extension springs last 4 to 12 years, or 5,000 to 15,000 cycles, and when one snaps without a safety cable through it, the loose end can travel.
One spring or two
A 16 ft double door weighs 300 to 450 lb and often needs two torsion springs. When one fails, the other has done the same number of cycles and is close behind.
How a Broken Spring Call Goes, Start to Finish
-
You call, we ask three things
Door size, single or double, and whether the spring is above the door or beside the tracks. That tells us what to bring so the repair finishes in one visit. Phones are answered Monday to Friday 7:00 am to 7:00 pm and Saturday 8:00 am to 5:00 pm.
-
Measure and quote on site
We measure the old spring by inside diameter, wire size and length, weigh or calculate the door, and give you a written itemized price before touching anything.
-
Release tension, swap, wind
With the door closed and the opener disconnected, we unwind the remaining spring, pull the shaft, fit the new springs, reset the drums and cables, and wind to the turn count the spring calls for.
-
Balance and safety test
We lift the door by hand to the halfway point. A balanced door stays there. Then we reconnect the opener and run the contact reversal test with a 2x4 flat on the floor; the door must reverse within 2 seconds of touching it.
The Specs That Matter on a Torsion Spring
Cycle rating decides how long it lasts
One cycle is one full open and close. Standard residential torsion springs are rated for about 10,000 cycles, high-cycle springs for 25,000, and max-life springs for 80,000 or more, as of 2026. A supplier table for a 2 inch inside diameter, .243 wire, 28 inch spring shows 8 turns for 10,000 cycles and 6.6 turns for 25,000, which is why a longer, heavier spring wound fewer turns outlasts a short one.
Why springs break on cold mornings here
Spring steel gets more brittle as temperature drops, and fatigue cracks that have been growing for years open up on the first cycle of a freezing morning. Murfreesboro has a cold season from November 28 to February 26 with a January average low of 31 F. Search demand for garage door repair here roughly triples in December and January, and broken springs are a big part of it.
Reading the old spring
A torsion spring is described as inside diameter by wire size by length, for example 2 inch by .243 by 28 inch. DASMA publishes a colour code for torsion and extension springs in its Technical Data Sheet 171 so the wire size can be read from the paint on the end. We measure rather than trust the paint.

A 16 ft steel double door in a 2006 subdivision home with one of two original torsion springs broken. Both springs replaced as a matched pair, cables and drums inspected, door balanced: $150 to $350 all in, about an hour on site. A frayed cable moves it to the $200 to $500 spring and cable price, and we tell you before we start.

Spring Replacement Questions We Hear
How do I know the spring is broken?
Look above the door with it closed. A broken torsion spring shows a gap of an inch or two in the coil. If you pull the red emergency release and the door is too heavy to lift, or lifts crooked, a spring or cable has failed. Do not keep running the opener; the drive gear or trolley will be next.
Can you replace just the broken spring?
On a two-spring door we replace both. The second spring has been through the same cycles and typically fails within months. The extra spring adds $15 to $30 in parts; a second trip fee later costs more.
How long will the new springs last?
A standard 10,000-cycle torsion spring lasts 7 to 15 years in national data, depending on how often the door moves. A 25,000-cycle spring costs more up front and is rated for two and a half times the cycles on the same door; ask us for the per-job premium.
Is it safe to open the door with a broken spring?
Not by yourself on a double door. A 16 ft door weighs 300 to 450 lb and with the spring gone that weight is in your hands. The safer answer is to call and wait; most spring calls are finished within the hour on site.
Do I need a permit for spring replacement in Murfreesboro?
No. Replacing springs is a repair, not an alteration. The job also sits under the $3,000 project value where Tennessee requires a Home Improvement licence in Rutherford County. A full door replacement is a different question, and a new door install is where we walk through the City permit position.
Work That Often Goes With New Springs
The two spring systems compared explains how each lifts the door and when a conversion is worth it.
Frayed or jumped lift cables are checked on every spring visit and replaced in the same trip when needed.
An opener that strained against a broken spring may have a worn drive gear or trolley that shows up once the door is balanced again.
A yearly balance and lubrication visit catches a tired spring before it breaks on a January morning.
Door Stuck? Tell Us What It Is Doing
A door that will not lift, hangs crooked, or stops a few inches off the floor is usually one failed part. Call during posted hours or send the symptoms and we will come out, name the part, and put an itemized price in front of you before we touch it.
