Trusted Garage Door Parts for Tarzana Homeowners
A garage door has roughly 120 individual parts, and when one of them fails, the whole system stops working. In Tarzana, where summer heat pushes 100 degrees and winter nights dip into the 40s, metal fatigues, rubber cracks, and springs snap. Since 2015, Servo Garage Doors has repaired over 18,000 garage doors across the San Fernando Valley, and the single thing that separates a door we fix from one that fails again in six months is the quality of the parts we put in. Marcus Deller runs our Tarzana operation, and the rule he drills into every technician is simple: show the customer the failed part before you quote a replacement. That’s Clause 4 of The Haven Standard, and it’s non-negotiable. If you need Garage Door Parts - Tarzana, call (424) 372-1317. A live person answers, 24/7.
What Our Garage Door Parts Service Includes
Every part we install in Tarzana gets the same treatment: a written price before work starts, a photograph of the failed component before we touch it, and a documented record of what we installed when we leave. Here’s what that looks like part by part.
Torsion Spring
A torsion spring is the coiled steel shaft mounted horizontally above your door opening. It stores the mechanical energy that lifts the door, and it’s under enough tension to cause serious injury if it lets go. We measure the wire diameter, inside diameter, and length before quoting a replacement, because putting in a spring that’s “close enough” gives you a door that drifts, binds, or fails early. Servo Garage Doors Tarzana replaces torsion springs with properly rated parts matched to your door’s weight and cycle count.

Extension Spring
Extension springs run along the horizontal tracks on either side of the door and stretch when the door closes. Lighter-duty than torsion springs, they’re common on older Tarzana homes with single-width garage doors. We include a safety cable inspection with every extension spring job, because an extension spring without a containment cable becomes a projectile if it breaks. The replacement spring gets rated to your door’s exact weight, and we photograph the old spring before removing it.

Cables & Drums
Lift cables connect the bottom corners of the door to the cable drums mounted on the torsion tube. When a cable frays or snaps, the door hangs unevenly and the remaining cable takes double the load. In Tarzana, we see cable failures most often on doors that were installed with undersized cable for the door’s weight. Servo replaces cables in pairs, checks the drums for wear grooves, and rebalances the door so both sides lift evenly.

Rollers & Hinges
Rollers are the wheels that ride inside the vertical and horizontal tracks. Hinges are the metal plates that connect the door’s sections and let it bend as it travels. Nylon rollers with sealed bearings run quieter than steel and don’t need lubrication as often, which matters in Tarzana garages that double as workshops or home gyms. We inspect every roller and hinge during a parts call, and we’ll tell you if one is close to failing, not just the one that already did.

Weatherstripping
Weatherstripping is the flexible seal that runs along the sides and top of the opening. When it splits or pulls away, dust from the Santa Ana winds gets into your garage, and so do the insects that follow the warmth of your water heater. Servo replaces weatherstripping with UV-stable vinyl or EPDM rubber that won’t harden and crack in Tarzana’s dry heat. It’s an inexpensive part, and a new seal also cuts the draft that pulls hot air into your garage in August.

Bottom Seal
The bottom seal is the rubber or vinyl strip attached to the bottom of the door, held in place by a retainer channel. It flattens over time and splits at the corners, letting water in during the winter rains that roll through the Valley. A new bottom seal keeps out rain, leaves, dust, and the rodents that look for garage shelter in the fall. We stock multiple seal profiles to match your specific door brand, including beaded, T-style, and channel-fit seals.

Brands We Service for Garage Door Parts

We work on every major garage door brand sold in Tarzana, and we stock OEM parts for most of them on the truck. Clopay doors are some of the most common we service in the Valley, and we carry their factory bottom seals, hinge assemblies, and spring hardware. A Clopay door from a track home in the hills above Ventura Boulevard often uses specific hinge geometry you won’t find on a generic part at a hardware store.
Amarr doors show up frequently in Tarzana’s newer builds and townhome complexes. Their commercial-grade spring systems run higher cycle counts, and we match replacements to the cycle rating, not just the wire size. Wayne Dalton is the brand we see most often with torque-master spring systems, the enclosed tube design that sits inside the torsion shaft. Those require different tools and different parts than a standard torsion spring, and we carry them. Craftsman is a frequent find on older homes that predate Tarzana’s 1990s construction boom. Whether you have one of these or any other make, we source the right part and give you the written price before anything gets touched.
Before
AfterSigns You Need Garage Door Parts Right Now
- The door opens unevenly or jerks on the way up. This usually means a cable has slipped or is beginning to fray, or one spring is doing more work than the other. Ignoring it puts stress on the remaining parts, and a snapped cable under load can whip unpredictably. Call us before the door gets stuck halfway.
- You hear a grinding, squealing, or rattling noise while the door moves. Grinding often means a roller bearing has failed or a hinge is binding. Squealing can be a spring rubbing against itself or the shaft. Left alone, the vibration transfers to the brackets and tracks, and a $40 roller replacement becomes a $200 track realignment.
- The door feels heavier than it used to. If you pull the manual release cord and the door is hard to lift, the springs are losing tension. Properly balanced doors should feel like they weigh about 10 pounds when you lift them by hand. A door that fights you is a spring that’s near the end of its rated cycles.
- You can see daylight under the door or the seal is crumbling. A perished bottom seal means water, dust, and pests are walking into your garage every day. In Tarzana, where the Santa Anas carry fine grit from the foothills, a split seal also lets in enough dust to coat everything stored in the garage within a month.
- The door stops and reverses or won’t stay closed. This is often a worn limit switch or a travel adjustment problem in the opener, but it can also be a roller catching on a worn hinge. When the door reverses on its own, the safety system is doing its job; the question is which part made it trip.
Our Garage Door Parts Process - Step by Step

- 1
You call (424) 372-1317 and describe the symptom. A live person answers, even at 3 a.m. during a holiday. We ask the right questions: what noise it makes, whether it opens at all, how old the door is. That way the technician shows up with the likely parts already loaded, which saves you a second trip charge.
- 2
The technician arrives and inspects the door, not just the broken part. We check the tracks, the balance, the rollers, the hinges, the springs, and the opener. The failed component gets measured and photographed before anything is quoted. That photograph is part of the documentation you receive whether you hire us or not.
- 3
You receive a flat, written price and a written scope of work. This is Clause 1 of The Haven Standard. The price on the page is the price on the invoice. If the scope changes because we find something else wrong, you get a new written price before that work happens. Nobody starts swinging a wrench until you say go.
- 4
We install the right part, matched to your door’s make and weight. No universal-fit shortcuts. A torsion spring gets rated to your door’s weight and cycle count. A cable gets matched to the drum. A roller gets matched to the track profile. When the work is done, we run the door through a full cycle test and check the balance by hand.
- 5
You get a documented photo record of everything we found and everything we did. That’s the Servo rule that’s been in place since day one in 2015, and it’s why Clause 4 of The Haven Standard exists. You’ll see the failed part we removed and the new part we installed, plus the written warranty on the part and the labor.
How Much Does Garage Door Parts Cost in Tarzana?
Garage door parts pricing in Tarzana depends on the part, not on how the technician feels that day. A torsion spring replacement in Tarzana runs $180 to $340, depending on the wire gauge and cycle rating. Cable repairs cost $130 to $250. Roller replacement on a standard two-car door runs $110 to $220. Weatherstripping and bottom seals are the lower end, typically $70 to $150 installed. Here’s the full range:
- Torsion Spring - $180-$340
- Extension Spring - $130-$250
- Cables & Drums - $130-$250
- Rollers & Hinges - $110-$220
- Weatherstripping - $70-$150
- Bottom Seal - $70-$150
Three things move the price. The first is the part itself: a 20,000-cycle spring costs more than a 10,000-cycle spring, and it matters which one goes on your door because they move. The second is the door’s weight and size: heavier wooden doors and double-wide openings need sturdier hardware. The third is whether multiple parts have failed, which is common when a spring snap takes out a cable on the way down. What you won’t pay for is mystery. Our estimate is free, and it comes as a written number before any work starts. You’ll know exactly what the part costs and exactly what the labor costs. That’s not a special offer; it’s how every Servo job in Tarzana has worked since 2015.

Frequently Asked Questions - Garage Door Parts in Tarzana

Garage door parts are the individual components that make the door open, close, seal, and stay balanced. They include torsion and extension springs, cables, drums, rollers, hinges, tracks, weatherstripping, bottom seals, and the brackets that hold everything together. When one part fails, it usually takes stress onto the parts around it, which is why replacing a broken part promptly costs less than waiting. Servo Garage Doors Tarzana stocks parts for all major brands and identifies the exact failed component before quoting a replacement.
Most single-part replacements take between 45 minutes and two hours once the technician is on site. A torsion spring replacement typically runs about an hour; a full roller and hinge swap on a double door can take closer to two. If we need to order a brand-specific part that isn’t on the truck, we give you a timeline before any work is scheduled. The estimate is free, and the written scope tells you exactly how long the job will take.
In Tarzana, you’re looking at $70 to $150 for weatherstripping or a bottom seal, $110 to $220 for rollers, $130 to $250 for cables, and $180 to $340 for a torsion spring. The exact price depends on your door’s weight, the part’s cycle rating, and whether anything else failed alongside it. You get a flat, written price before work starts, and that price is honored. Call (424) 372-1317 for a free estimate, and you’ll have the number in writing, not a verbal “around about.”
Yes. We service Clopay doors across Tarzana and stock their factory seals, hinges, and spring hardware.

Yes. A snapped spring or a broken cable leaves your door either stuck open or slammed shut, and both are problems you want addressed the same day. Our Tarzana team answers calls 24/7, including holidays, with a live person, and we dispatch a technician with the likely parts already loaded.

Every part we install in Tarzana carries the manufacturer’s warranty plus our 365-Day Done Right Promise. If a repair isn’t right, serviced properly, we make it right within the year.

Clear the area inside the garage by a foot or two from the door tracks and motor. Park the car outside if it’s a single car garage so the technician has room to work. You don’t need to remove anything from the door itself, and you don’t need to have any tools ready. When we arrive, we’ll inspect the door, photograph what we find, and give you a written price before any work begins.
