AfterThe Mainspring Garage Door Co. Guarantee
We stand behind every garage door repair, installation, and opener service we complete in Van Nuys. Our 90-Day Done Right Promise means exactly what it says: if the work isn’t right, we come back and make it right. No paperwork to file, no argument, no charge. That promise is written on every job ticket before we leave your driveway. We’ve been serving Van Nuys and the San Fernando Valley since 1984, and we’ve learned that a guarantee only matters if you honor it without making the customer fight for it. When we say “done right,” we mean the door runs quiet, the opener responds clean, and you don’t have to think about it again until your next seasonal tune-up. That’s the essential foundation for your home, and it’s how we’ve stayed in business for over 42 years.
What’s Covered
- Workmanship on every repair and installation. Our technicians are trained journeymen who work under the K.E.Y.S. code: Krafted right, Every time, Your home first, Standing behind it. If a spring we install settles differently than expected, or if an opener programming needs adjustment within 90 days, we return and correct it at no cost.
- Parts we supply and install. We carry springs, cables, rollers, hinges, and openers from all major brands on every truck in Van Nuys. If a part we installed fails due to defect or our handling within the promise period, we replace it and handle the labor ourselves.
- Cleanup and respect for your property. We leave the work area as we found it, minus the garage door problem. Old springs, worn cables, and packaging are hauled away. Our technicians wear uniforms and have passed background checks, so you know who’s in your garage.
- On-time arrival as scheduled. We will be there when we say. If we’re running behind due to Valley traffic or an unexpected complication on a prior job, our office calls you with a real ETA, not a window that stretches for hours.
- Honest, upfront pricing with no surprises on the bill. The flat price is stated before any work begins. You’ll see the total on the written estimate, and that number doesn’t change unless you ask for additional work. We believe in a square deal.
Our Satisfaction Promise
If something about our work doesn’t sit right with you, we want to know. Call us at (747) 836-1998, and a live person will answer, 24/7, including nights, weekends, and holidays. No phone trees, no voicemail, no after-hours answering service. Describe what happened, and we’ll schedule a return visit at the earliest time that works for your schedule. Our technician arrives, assesses the concern, and fixes it. We don’t ask you to fill out claim forms or wait for a manager’s approval. The 90-Day Done Right Promise is already in writing from your original job, so there’s nothing to negotiate. We’ve honored this same guarantee since Carl Dutton founded Mainspring Garage Door Co. in 1984, and we still answer the phone ourselves. Most concerns in Van Nuys are resolved in a single return visit because our trucks stay stocked with the common parts that might be needed. If we missed something the first time, we own it, and we make it right.
Licensed & Insured Backing
California requires garage door contractors to carry proper licensing and insurance, and we maintain both without exception. Our licensing means the state has verified our technical training and business standing. Our insurance and bonding protect your property if the unexpected occurs. These aren’t marketing badges for us. They’re the real guarantee behind the paperwork, the foundation that lets us promise “done right” and mean it. When you hire Mainspring Garage Door Co. in Van Nuys, you’re not getting a handyman with a ladder and a hope. You’re getting a state-licensed, insured, and bonded company that has survived 42 years in the San Fernando Valley by doing what we said we’d do. Carl Dutton built this business on that principle, and we still operate by it on every job, every time.
Standing Offers That Never Disappear
We don’t run flash sales or bait-and-switch promotions. These offers are always available to Van Nuys homeowners:
- $50 Off Any Repair Over $250
- Free Second Opinion on any written estimate you’ve received from another company
- $89 Seasonal Tune-Up to catch wear before it becomes a breakdown

What We Ask of You
A guarantee works both ways. We ask that you operate the door normally and report any concern within the 90-day period. Keep your written job ticket, which shows the work performed and the promise in print. For openers and moving parts, an annual tune-up extends the life of the equipment and often catches issues before they require emergency service. Our $89 seasonal tune-up is priced to make that easy for Van Nuys families.

We answer every call with a live person, 24/7, and we prioritize genuine emergencies, doors stuck open or off-track that compromise security.
