Lakeland, FLCrystal Lake, Lakeland
Crystal Lake homes date mostly to the mid-1970s, which means original extension spring setups on standard steel doors. Here's what that means for repair.
Local causes
Crystal Lake sits about four miles from Lakeland, and the houses here skew older than a lot of what we see across the rest of the service area. The median home here went up around 1975, ahead of the broader 1966-1999 stretch that covers most of the 25 communities we work in. That decade matters for springs specifically. A lot of garages from the mid-70s were built with a single steel door, 7 feet tall and either 9 or 16 feet wide, hung on a pair of extension springs stretched along the horizontal tracks rather than a torsion bar over the opening. Those springs run exposed, with no shaft and no center bearing plate to carry the load evenly. Forty-plus years of daily cycling, Central Florida's mild but humid climate working on the coils, and in a lot of cases no containment cable - that combination is why extension spring failure shows up more often here than in the newer subdivisions further out toward Highland City or Jan Phyl Village.
Warning signs
On a door this old, a broken spring rarely announces itself quietly. You hit the opener button and the door either doesn't move, or it lurches up a few inches and stalls because the opener alone can't lift a 7-by-16 steel door with no spring assist.
If one of the two extension springs let go and the other held, the door may hang crooked in the opening, higher on one side than the other. Some owners hear the snap itself - a loud bang from the garage, often mistaken for something falling off a shelf.
If the spring has been stretched and re-hooked over the years rather than replaced, you may also see a coil that's visibly gapped or uneven compared to its pair. None of that means the opener is broken. It means the springs, which do the actual lifting, are no longer doing their job.
Job timing
We don't post a fixed window for this because it depends on what we find once the door is open - whether it's a clean two-spring swap or there's wear on the pulleys, cable, and rollers that came with that original 1975 hardware. What we can tell you is that extension spring jobs on a standard single door are usually quicker than a torsion conversion, since there's no shaft to pull and no drums to set. If the pulleys or the safety cables are also worn through from the same decades of cycling, that adds time, because we're not leaving a door running on parts that are one failure away from the same call again.
The repair
On a door built when extension springs were standard, we replace both springs as a pair even if only one broke - the second one has carried the same miles and is close behind.
We check the pulleys and the stationary cable pulley bracket, since those wear right alongside the springs and are often original to the door. If there's no containment cable running through the spring, we add one; that's a cable threaded through the coil so a spring under tension can't whip loose if it ever lets go again.
We also check the track alignment on both sides, because a door that's been dropping unevenly on one bad spring tends to knock the rollers out of true.
We won't tell you a torsion conversion is required if the extension setup is sound - sometimes the right fix is putting good springs back on the hardware that's already there.
Watch-outs
The honest limitation here: if the door panel itself has rusted through at the bottom section or the track is bent from being forced while the spring was broken, spring replacement alone won't fix the door, and we'll tell you that rather than charge you for a spring that won't solve the real problem. We also don't stock every obsolete extension spring length on the truck - some of the coil lengths used on mid-70s doors aren't common sizes anymore, so a close match sometimes means we're sourcing the specific length rather than grabbing one off the shelf. On a door this age, that's worth knowing before you call.
Questions
A lot of it comes down to age. Crystal Lake's median home was built around 1975, when single-door garages commonly used extension springs along the tracks instead of a torsion bar. Those springs have been cycling for decades, and Florida's humidity adds to the wear on exposed coils.
We don't recommend it. If one extension spring failed, the matching spring on the other side has run the same number of cycles and is close to failing too. Replacing both at once means you're not back out here in a few months for the second one.
If it doesn't have one already, we add it during the repair. It's a cable run through the spring coil so that if the spring ever breaks again, it can't whip loose inside the garage. A lot of original 1970s installs didn't include one.
About four miles from Lakeland, where the company is based. We don't keep a branch or depot in Crystal Lake itself - the truck comes from Lakeland for the job.
