Spring-size opener-compensation strain
When the spring doesn't match the door's actual weight, the opener works harder to compensate, and that wear looks like an opener problem when the real fault is upstream.
Del Mar, Encinitas
Torsion spring repair for Del Mar homes, most built around 1970. Our Encinitas crew makes the six-mile drive and matches springs to the door you actually have.

Pricing
We don't quote a flat number for spring repair over the phone, and we won't invent one here either. What drives the cost on a Del Mar job is the door itself: whether it's a single torsion spring or a matched pair, what the door weighs, and whether the drums and cables need replacing along with the springs. Del Mar's housing skews to homes built right around 1970, the early edge of the 1970-2003 wave that shaped most of this service area, and those early doors often carry heavier wood or early steel panels than what went up in the 1990s. Heavier door, heavier spring, more labor to set the tension safely. On the other end, a household income here well above the area median means we also see doors upgraded with insulated panels or heavier openers bolted onto old torsion hardware that was never sized for the extra load - that mismatch is its own repair, not just a spring swap. The honest answer is we tell you the number after we've looked at the door, not before.
Watch-outs
The trouble on a lot of Del Mar calls isn't the spring itself, it's what's been done to the door since 1970. A house built in that window has had five decades to collect a replacement opener, a replaced bottom section, maybe a spring swapped once already by someone who grabbed whatever size was on the shelf.
When the spring doesn't match the door's actual weight, the opener works harder to compensate, and that wear looks like an opener problem when the real fault is upstream.
We also see this in a smaller, tighter pocket like Del Mar's roughly 1,890 households more than in the bigger tracts nearby - fewer doors means fewer contractors have serviced this exact era of hardware recently, so mismatched parts sit longer before anyone catches them.
Add a mild coastal climate that doesn't put extreme thermal stress on steel, and springs here often fail from fatigue and bad sizing rather than from any dramatic weather event - which means the failure creeps up quietly instead of announcing itself.
DIY or pro
We'll say this plainly: a torsion spring under tension can break a hand or worse, and winding bars aren't optional equipment you can skip. If you've got an extension spring setup and the door is light, some homeowners handle a cable or roller swap themselves. Springs are a different category of job. We'd rather you call us than search for a video and wing it, and that's not a sales line - it's the one part of this trade where the margin for error is a hospital visit, not a redo. If your door is original to a 1970-era build and you're not sure what you're looking at, that uncertainty alone is a reason to have someone who's seen this hardware take a look before you touch a wrench to it.
The repair
We start by measuring the door's actual weight and matching a spring to it, not to whatever wire size happens to be on the old one.
On a lot of Del Mar homes that means working with torsion hardware original to a 1970 build, which uses shaft and drum dimensions you don't see on newer stock doors.
We pull the old spring, check the shaft, cables, and drums for wear, and replace whatever's fatigued along with the spring itself - a new spring on a worn cable is a callback waiting to happen.
Once the new spring is wound to the right number of turns for the door's weight, we run the door through a full cycle by hand before touching the opener, checking balance at several points along the track. If the door doesn't hold position on its own with the opener disconnected, something's still off, and we don't call the job done until it does.
Timing
The drive out from our shop in Encinitas to Del Mar is six miles, which keeps a spring job here on the same schedule as calls closer to home rather than pushing it to the far end of the day. The repair itself is usually a single visit - most torsion spring jobs run under two hours once we're on site, longer if cables or drums need replacing too. What we won't do is promise a same-day slot before we've talked to you about what's actually broken; a broken spring on a door that won't open at all gets priority over a door that's just noisy.
On the truck
We stock the common torsion spring sizes that cover most residential doors, but Del Mar's older stock - built closer to 1970 than the newer end of the area's 1970-2003 range - sometimes needs a wire diameter or shaft length we don't have sitting on the truck. When that happens we order it rather than force a spring that's close enough, because close enough on a torsion spring means the door drifts or slams within a year. We carry standard cables, rollers, and drums for same-visit replacement, and for double doors we carry matched pairs so you're not left with one new spring doing a two-spring job.
Questions
If your neighbor's house went up later in the area's 1970-2003 building run, their door and hardware may be a different generation than yours. Homes closer to 1970 often carry heavier original doors and different shaft dimensions, which means a different spring size even on the same street.
No. We run out of Encinitas, about six miles away, and bring what a typical spring job needs on the truck. If your door needs an uncommon part, we order it rather than substitute something close enough.
Often yes, especially on older double doors. If one spring failed from fatigue, the other has usually logged the same number of cycles and isn't far behind. We'll tell you what we see on your specific door rather than push a blanket rule.
No. Torsion springs are wound under heavy tension, and adjusting one without the right bars and technique is how people get hurt. This is one job where calling for a repair costs a lot less than a mistake.
