You Don't Need to Know What's Wrong.
Just Tell Us What It's Doing.
Most people don't know what a torsion spring is until it breaks. That's fine. You don't need garage door vocabulary to call Swain Garage Doors. You just need to describe the symptom. We diagnose the cause on-site and explain what's wrong in plain terms before any work starts.
Here are the most common symptoms we hear and what they usually mean.
Door Won't Open At All
Usually a broken torsion spring or a failed opener motor. Both are same-day repairs in most cases. Do not try to force it. A door under spring tension is heavy.
Door Won't Close Fully
Often a sensor alignment issue, a bent track, or a limit setting on the opener. We diagnose which one on the first visit and fix it.
Door Is Slow or Feels Heavy
Spring tension dropping, worn rollers, or an opener straining against a door it cannot balance. Catching this early can prevent an emergency call.
Loud Bang or Snap
Almost always a broken spring. The sound is distinctive. The door will usually feel extremely heavy immediately after.
Grinding, Squeaking, or Rattling
Worn rollers, loose hardware, or dried-out hinges. A quick service visit catches it before it accelerates wear on other parts.
Door Looks Crooked or Uneven
One side higher than the other usually points to a broken cable or spring tension issue. The door should not be operated until it is assessed.
Opener Not Responding
Could be the remote, sensors, motor, or logic board. We work through the diagnostic sequence on-site before recommending replacement.
Door Came Off Track
Do not try to run it. An off-track door can cause serious damage to the door and anyone nearby. We reset, realign, and identify what caused it.
What We Repair
Every Component. Every Configuration.
Garage door systems have a lot of moving parts. We work on all of them, across new construction, mid-century homes, historic configurations, and everything in between.
Mechanical Components
Springs
Torsion and extension spring repair and replacement, properly sized for your door's weight and cycle demands. Full spring repair details →
Cables
Frayed, snapped, or worn cables cause uneven door movement and put stress on everything else in the system. We replace both sides when one shows wear.
Rollers
Worn or cracked rollers are a major source of noise and drag. Steel, nylon, and sealed bearing rollers depending on your track and usage.
Tracks & Alignment
Bent tracks, misaligned sections, and off-track doors, including low-headroom configurations found in some homes.
Hinges, Brackets & Hardware
Broken hinges and worn bottom brackets are often the overlooked cause of noise and uneven operation. We check the full hardware set on every call.
Opener & Electrical
Opener Motor & Logic Board
Motor failures, capacitor issues, and logic board problems across all major brands, LiftMaster, Chamberlain, Genie, Craftsman. We diagnose and repair before recommending replacement.
Safety Sensors
Misaligned or failed photo-eye sensors are a common cause of doors that won't close. We align, test, and replace when needed.
Remotes & Keypads
Remote programming, keypad replacement, and smart home integration. We set everything up and confirm it works before leaving.
Battery Backup Systems
Opener battery backup installation and service, especially relevant for Commerce City and Brighton homes where power outages are a real consideration.
Opener Replacement
When repair doesn't make financial sense, we install quiet belt-drive and smart Wi-Fi openers with honest guidance on what's worth the upgrade. Opener installation details →

5 Star Rating • 130 Google Reviews
"Torsion spring snapped and had to keep the door open with a post. Called in the AM and door was repaired the same day. Does not get better than this."
"That company told me I needed to replace my spring, rollers, and sensors and quoted me $1350. I got a second opinion from Sam who said I likely just needed an alignment of the sensors and he came out the next morning and completed the work for $250... Does honest business and great work!"
"Sam came to my house and did a wonderful job quickly and easily! He fixed our broken cables and had the garage doors running like new in less than 40 minutes. I am going to have him come to my new house ASAP!"
Pricing
Why These Prices Look Different
Most of the garage door companies competing for the top of your search results paid a lot to be there. That overhead has to come from somewhere, and it usually shows up in the service call fee, the parts markup, or the final number on the invoice.
Swain Garage Doors keeps things lean on purpose: no franchise fees, no race-to-the-top ad spend, no dispatch center taking a cut. The estimate is always free, the prices are posted because they're worth posting, and the number you see is the number you pay.
FAQ
Garage Door Repair Questions
The questions homeowners across the Denver metro actually ask us.
How fast can you get out for a repair?
Most calls in our primary service area, Thornton, Northglenn, Westminster, Broomfield, Commerce City, are handled same-day. Arvada, Denver, and Brighton are typically same-day as well depending on the schedule. Call directly for the most accurate timeframe. We don't do four-hour windows. You get a real arrival time.
My spring broke. Is that a same-day repair?
In most cases, yes. We carry standard torsion and extension spring sizes on the truck. If your door has a non-standard configuration, low headroom, oversized door, original hardware, there's a chance a specific spring needs to be sourced, but we'll tell you that on the phone after you describe the setup. More about spring repair →
Should I repair or replace my garage door?
The honest answer is: repair unless the door itself is structurally compromised. Springs, cables, rollers, openers, all of those are component replacements that don't require touching the door. If panels are severely damaged, the door is warped, or it's an extremely old door with no parts availability, replacement might make more sense. We'll give you a straight assessment on-site. New door installation info →
Why did my spring break? Will the new one break too?
Springs have a finite cycle life, typically 10,000 cycles for a standard torsion spring, which works out to 7 to 14 years depending on usage. When they fail, it's usually because they've hit the end of their rated life, not because something catastrophic happened. Replacement springs are the same product. They'll last another full cycle life with proper installation and occasional lubrication. We can also install high-cycle springs rated for 20,000+ cycles if longevity is a priority.
Is it safe to operate a garage door with a broken spring?
No. A door with a broken spring relies entirely on the opener motor to lift what is typically a 150 to 300 lb door it was never designed to lift alone. Operating it risks burning out the opener, damaging cables, and creating a fall hazard. Leave the door in whatever position it's in and call us. Most spring repairs are same-day. It's worth waiting.
Do you charge a diagnostic or service call fee?
No. The estimate is free. We show up, assess the situation, and tell you what the repair costs before any work starts. If you decide not to proceed, there's no charge for the visit. We think that's how it should work.
