About Swain Garage Doors
More about Sam and the business →
Sam Built This Business Because He Knew It Could Be Done Better.
After years in the industry, Sam saw the same problems over and over: vague estimates, techs who upsell instead of diagnose, invoices that don't match the quote. He started Swain Garage Doors to be the company he'd actually want to call.
Swain Garage Doors is a family business in every sense. Sam and his family live and work in the Denver metro, and that community connection shows up in how every customer gets treated. When you call, you're reaching people who care whether the job was done right.

Why Swain Garage Doors
Not a Franchise or a Call Center
In a market full of companies spending on ads, the difference shows up when the tech arrives at your door.
You Talk to the People Who Do the Work
No call center routing your job to whoever is available. When you contact Swain Garage Doors, you reach the team doing the work, and they show up as scheduled.
Price Before We Start. Every Time.
A real number before any work begins. You approve it, then we start. If anything changes mid-job, you hear about it before it happens, not on the invoice.
No Commission to Replace
Franchise techs are often paid per sale. That shapes every conversation they have. If your door can be fixed, we fix it. We're not going to sell you a new door to make a larger ticket.
Repair-First Approach
Replacement is the right answer sometimes. When it is, we'll tell you and show you why. When it isn't, you won't hear it from us. We don't build the business on replacement volume.
Google Guaranteed
LSA-verified, background-checked, licensed, and insured. The full credential set, without the franchise markup built into your service call.
Colorado Native, Family Owned
Swain Garage Doors was built here and operates here. The people doing your job live in the same communities you do. That shows up in how the work gets done.
Still not sure? Call us directly and get a straight answer about your door.

How It Works
What Happens When You Call
No dispatch relay, no four-hour window, no surprise invoice. Here's the sequence from first call to finished job.
01
Call Swain Directly
You reach us. Describe what the door is doing. You don't need technical terms. We schedule the call and give you a real time, not a window.
02
On-Site Diagnosis
We arrive, inspect the full system, and identify the problem. You get a plain-language explanation of what's wrong, what caused it, and what the repair involves.
03
Price Before We Start
You get the cost before any work begins. You approve it. If the scope changes for any reason, you hear about it before it happens, not on the invoice.
04
Repair and Final Check
The repair is completed and the full system is tested: balance, travel, opener force, sensors. You get a door that works correctly, not just a door that opens.
Real Reviews
What Denver Metro Homeowners Say
5.0 stars on Google. Here's what people actually wrote.
★★★★★
"Sam showed up same-day, explained what was wrong, and walked me through the options without any pressure. The repair was done right the first time and the door is running smoother than it has in years. It's refreshing to work with a local owner-operator who actually takes pride in his work."
★★★★★
"Another company quoted me $1,350 to replace the spring, rollers, and sensors. Sam came out and said I likely just needed a sensor alignment — and fixed it for $250. Does honest business and great work."
★★★★★
"Sam swung by same-day for an analysis, came back the next morning to replace the springs and rebuild the hardware. Repair was quick, works great, and runs quieter than before. I think I made a solid choice."
Our Guarantee
The Only Company in Colorado Offering This.
Every new door installation comes with a 10-year parts warranty and a lifetime workmanship guarantee. If something goes wrong with how the job was done, we make it right. No questions, no runaround.
No franchise in this market offers both. This is what standing behind your work actually looks like.
10-Year Parts Warranty
All parts on new installations are covered for 10 years based on manufacturer determination. We act as the warranty holder on your behalf since we purchase and install the door through our dealer account.
Lifetime Workmanship Guarantee
If we did something wrong in the installation, we come back and fix it. That commitment has no expiration date.
10-Year Spring Replacement Warranty
Springs replaced by Swain Garage Doors are covered for 10 years. High-cycle springs rated for 20,000+ cycles, installed and backed by us.
Spring warranty requires two preventative maintenance visits per year at $99 each to remain active. This keeps the system performing correctly and the warranty valid.
Pricing
Flat Rates.
Flat Rates.
No Zip Code Markup.
Some companies price the job based on the neighborhood. We don't. The prices listed here are what we charge — every customer, every job, every time.
Springs are replaced as a pair using high-cycle springs rated for 20,000+ cycles with a 10-year warranty. When one breaks, the other is close behind. You get a better product and a longer-lasting system overall.
