AfterTrusted Garage Door Parts for Van Nuys Homeowners
Garage Door Parts - Van Nuys typically cost between $110 and $340 depending on the component, and most replacements are completed in a single visit when the right parts are already on the truck. At Mainspring Garage Door Co., we’ve been sourcing, stocking, and installing quality garage door parts since 1984, and our trucks carry torsion springs, extension springs, cables, rollers, and weather seals for same-day service across the Valley.
We’ve worked on garage doors in Van Nuys for over 42 years, from the ranch homes near Van Nuys Airport to the mid-century builds in Lake Balboa and the hillside properties climbing toward Sherman Oaks. The San Fernando Valley heat cycles are hard on metal components, springs lose tension in the dry air, and bottom seals crack after summers of UV exposure. When a part fails, you want someone who knows which grade of steel holds up here, which brands stock reliable replacement hardware, and who will quote the flat price before touching a wrench. That’s how we’ve always done it. Call us at (747) 836-1998 for a free estimate.
What Our Garage Door Parts Service Includes
Torsion Spring
A torsion spring is the heavy-duty coil mounted above your door that does the actual lifting, counterbalancing hundreds of pounds of steel or wood every time you open or close. In Van Nuys, we see torsion springs fail most often in spring after the temperature swings of winter have stressed the metal, or after 8,000 to 12,000 cycles of normal use. When we replace a torsion spring, we match the wire gauge, inner diameter, and length to your specific door weight, install it with proper winding bars, and adjust the tension so the door stays balanced at every height.
Extension Spring
Extension springs run along the horizontal tracks on either side of the door and stretch to provide lifting force, common on older single-car garage doors throughout Panorama City and parts of Northridge. These springs wear at the loop ends where they hook into the pulley system, and a broken extension spring can send metal flying with dangerous force. We replace extension springs in matched pairs, install safety cables through the center of each spring to contain it if it breaks, and check that the pulley alignment hasn’t shifted on the track.
Cables & Drums
Lift cables wind around the drums at the end of the torsion tube and transfer the spring’s torque to the bottom corners of your door, lifting it evenly. In Van Nuys, cable fraying accelerates when doors run slightly off-track and the cable rubs against the edge of the drum or the cable slot. We inspect the full cable length, replace both cables as a set even if only one shows wear, and examine the drums for grooving or cracks that would damage new cables within months.
Rollers & Hinges
Steel or nylon rollers ride inside the track and carry the door’s weight as it moves, while hinges flex at each panel joint and keep the door sections aligned. After decades of dust from the Santa Ana winds working into the roller bearings, we’ve seen rollers seize completely in Valley homes, grinding the track and stressing the opener. We stock 2-inch and 3-inch stem rollers, nylon rollers with sealed bearings for quieter operation, and heavy-duty 14-gauge hinges for heavier wood doors, and we always check that the track spacing hasn’t widened before installing new hardware.
Weatherstripping
The flexible vinyl or rubber seal along the sides and top of your door frame blocks dust, pollen, and the occasional Valley heat wave from entering your garage. In Van Nuys, UV degradation is the primary killer, turning supple weatherstrip into cracked plastic that lets in fine dust and lets cooled air escape. We remove the old seal completely, clean the retainer channels of built-up grime, and install new vinyl or brush-style weatherstripping sized to your door’s exact thickness and frame gap.
Bottom Seal
The bottom seal is the rubber or vinyl gasket that compresses against your concrete threshold, keeping out water, rodents, and the leaves that blow through Valley neighborhoods every fall. Concrete spalling, threshold settling, and simple compression wear create gaps that let in everything the seal is meant to stop. We carry bulb-style, T-end, and beaded-bottom seals for every major track type, and we’ll tell you honestly if your threshold itself needs leveling rather than just a new seal.

Brands We Service for Garage Door Parts
We’ve worked on Craftsman openers and door systems since Sears dominated the Valley retail corridors in the 1980s and 1990s, and we still stock compatible parts for the red-belt and chain-drive units installed in thousands of Van Nuys homes. Whether you have a legacy Craftsman 1/2-horsepower unit from 2005 or a newer WiFi-enabled model, we know which gears wear first, which safety sensors fail in garage humidity, and which replacement remotes pair correctly without a trip to the big-box store.
Raynor doors have a strong presence in the custom homes of Encino and Calabasas, and we’ve sourced Raynor-specific torsion springs, pinch-resistant hinges, and insulated panel inserts for clients who want to maintain the original build quality. Our technicians are factory-familiar with LiftMaster, Chamberlain, Genie, Clopay, Amarr, Wayne Dalton, and Raynor, and we carry OEM or equivalent-grade parts for each. Whether you have a Raynor, a Craftsman, or any other make, we can help.
Signs You Need Garage Door Parts Right Now
- The door slams shut or falls too fast. This means a spring has lost tension or a cable has slipped or snapped, and the full weight of the door is no longer controlled. A falling garage door can injure someone or buckle the top section, and the problem will not fix itself.
- You see a visible gap in the torsion spring above the door. A broken torsion spring looks like a coil with a 2-inch separation, and your opener will strain or fail to lift the door at all. Operating the door with a broken spring burns out the opener motor and risks cable derailment.
- The door shakes, jerks, or binds in the track. Worn rollers develop flat spots, bent hinges bind at the pivot, and debris in the track forces the door out of alignment. Left alone, this wears the track itself and can pop a roller out of the guide.
- Light streams under the bottom of the closed door. A failed bottom seal or settled threshold creates gaps that admit dust, water, and pests, and in a Van Nuys summer, it lets your cooled garage air escape directly to the driveway.
- The opener runs but the door barely moves. Stripped gears, worn sprockets, or a disengaged trolley inside the opener unit can cause this, and forcing repeated cycles will destroy the motor. The right repair often costs far less than replacing the entire opener.
Our Garage Door Parts Process - Step by Step
- 1
Call and speak with a live person. When you call (747) 836-1998, day or night, a real Mainspring employee answers, takes your address in Van Nuys, and asks what you’re seeing and hearing. We schedule the first available appointment, typically same-day or next-morning for non-emergencies.
- 2
Arrive with parts on the truck. Our technician arrives in a marked vehicle with a stocked parts inventory, background-checked and in uniform. We carry multiple spring sizes, cable lengths, roller types, and seals so we can match what your door needs without a return trip.
- 3
Inspect and diagnose on site. We test door balance, check spring tension with a calibrated gauge, examine cables for fraying, measure roller wear, and assess seal compression. We explain what we find and show you the worn parts before quoting any work.
- 4
Quote the flat price before work begins. The price is stated upfront, in writing, with no hidden fees or after-hours surcharges. You approve it before we touch a tool. That is the Mainspring way, and it has been since 1984.
- 5
Install, test, and warranty the work. We install the parts, balance the door, test the safety reverse, lubricate moving components, and clean up. Every job carries our 90-Day Done Right Promise in writing: if it is not right, we come back at no charge, no paperwork, no arguing.
How Much Does Garage Door Parts Cost in Van Nuys?
A typical spring repair in Van Nuys runs $180-$340 depending on whether you need one torsion spring or a matched pair, the wire size required for your door weight, and whether the cables or drums show wear that should be addressed at the same time. Cable repair runs $130-$250, roller replacement is $110-$220, and opener repair ranges from $120-$320 when the issue is a failed part rather than full replacement.
Several factors move the price within these ranges. Heavier wood doors need thicker-gauge springs that cost more but last longer under load. Doors with unusual track configurations, like the low-headroom setups in some older Van Nuys apartments near Victory Boulevard, require specialized hardware. If multiple parts have failed together, a bundled repair often costs less per item than separate visits.
The best way to avoid overpaying is to get a written estimate that itemizes parts and labor separately, and to confirm the technician carries what your door needs before dispatch. At Mainspring, our estimates are free, our prices are flat and stated before work begins, and we never charge diagnostic fees just to tell you what is wrong. Call (747) 836-1998 for an exact quote on your specific door.
