Garage Door Specials in Thornton, CO
Call (720) 575-1024 when your garage door needs work and you’ll get a straight answer on what it costs before anyone touches a bracket. Servo Garage Doors Thornton runs seasonal specials because a door that gets attention now costs less than a door that fails at midnight in a Colorado freeze. Every offer below comes with the same flat, written price before work starts, the same documented photo record when the job is done, and the same 365-Day Done Right Promise on the repair. Here’s what we’re running right now in Thornton.
Current Offers
Spring & Roller Tune-Up: $79
We lubricate the torsion spring, rollers, hinges, and end bearing plates, then torque all track bolts and check balance on the door under spring tension. The written scope shows everything we touched and what we measured, and you leave with the photo record of the work. For Thornton homeowners with a door over six years old that hasn’t had a tune-up since the last presidential election, this is the cheapest insurance you’ll buy this year. Valid through December 31, 2026. Mention this offer when you call (720) 575-1024.
Free Second Opinion on Any Written Estimate
Bring us the paperwork from another company and we’ll walk the job with you, line by line, and tell you what’s actually broken and what isn’t. If the competing quote is lower and the work is comparable, we’ll tell you to take it; if it’s padded or the scope is wrong, you’ll see why in writing. This applies to garage door repair and opener work in Thornton, Northglenn, Westminster, and everywhere else we run trucks. No coupon code, no fine print. Valid through December 31, 2026. Mention this offer when you call (720) 575-1024.
New Garage Door Installation: Free Measure & Written Quote
We come out, measure the opening, check headroom and side clearance, and hand you a written quote with the door, hardware, labor, and haul-away priced separately so you can see where every dollar goes. Amarr, Clopay, Wayne Dalton, and Raynor are all available with a range of insulation and window options for Thornton’s summer sun and winter swings. You’re not obligated to buy anything, and the quote is yours to keep. Valid through December 31, 2026. Mention this offer when you call (720) 575-1024.
Opener Replacement Package: Free Opener Safety Check with Any Repair
When we’re out for any repair on the door, we’ll test the photo-eye sensors, the force setting, the limit switch, and the logic board on your LiftMaster, Chamberlain, Genie, or Craftsman opener. If it’s fine, we’ll say so; if the force setting is too high and the door could crush a child or pet, we’ll show you on the spot and quote the fix in writing before touching it. The test takes ten minutes and costs you nothing when bundled with a paid repair. Valid through December 31, 2026. Mention this offer when you call (720) 575-1024.
$50 Off Emergency Garage Door Service, 10 PM to 6 AM
When your door won’t close at 2 AM and you can’t lock up the house, we answer the phone with a real person, not a recording, and dispatch a named technician with an on-the-way text. We charge a flat written price before the truck moves, and this offer takes $50 off the emergency visit for calls placed between 10 PM and 6 AM, seven nights a week. Thornton, Northglenn, Federal Heights, and the surrounding neighborhoods, including holidays. Valid through December 31, 2026. Mention this offer when you call (720) 575-1024.
Senior & Military Courtesy: 10% Off Labor
If you’re 65 or older, or you’ve served, we take 10% off the labor portion of any garage door repair, opener repair, or parts replacement, and we don’t ask for a copy of your discharge papers. It applies on top of the written flat price, so the number you see on the quote is what you pay, minus the courtesy. This isn’t a marketing gimmick; it’s the least we can do for the people who’ve been through more garage doors than we have. Valid through December 31, 2026. Mention this offer when you call (720) 575-1024.
How to Redeem

First, call (720) 575-1024 and name the offer when you talk to a live person, 24/7, including holidays. Second, book the visit at a time that works for you: our dispatcher will tell you who’s coming and send an on-the-way text when the technician leaves. Third, mention the offer again when the technician arrives, before the written price is drafted. Every offer stacks with the flat-price guarantee under Clause 1 of The Haven Standard and the 365-Day Done Right Promise. You’ll get a written scope before any work starts and a documented photo record when it’s done. No coupons to print, no promo codes to type in; just say the words and the price matches.
Before
AfterWhat These Offers Do and Don’t Include
Every offer on this page includes the flat written price and written scope, delivered before any work begins, per Clause 1 of The Haven Standard. That means the number on the quote is the number you pay, and the scope is the list of parts and labor that number covers. You also get the documented photo record of what was found and what was done, per Clause 4, so there’s no argument later about what the technician touched. What these offers don’t include is anything you didn’t agree to in writing. If a technician finds a cracked torsion spring or a stripped gear in the opener, you’ll see the failed part photographed before anyone quotes a replacement, and you’ll sign off on the new price before the wrench turns. The 365-Day Done Right Promise covers every repair on this page: if it’s not done right, we make it right, backed by a terms page, not a handshake.
Why We Run Specials in Thornton

Thornton’s winters are hard on garage doors: the temperature swings from single digits to fifty degrees in the same week, and the bottom seal on a north-facing door takes direct sunlight all summer. We run specials because a $79 tune-up in October costs less than a broken torsion spring in February, and because a garage door that’s been serviced lasts years longer than one that’s been ignored. Marcus Deller, Owner & Lead Technician, has seen it from both sides: doors that got a little attention every year and doors that didn’t, and the difference is never subtle. Servo Garage Doors Thornton has serviced 18,000+ garage doors since 2015, and the data on that page isn’t marketing fluff; it’s a record of what happens when you treat a door like a machine instead of a fixture.
Frequently Asked Questions
Each offer on this page is valid through December 31, 2026, and we publish new offers in January and July. If you’re calling after the expiration date, ask the dispatcher what’s current; we typically replace a special with something comparable rather than yanking it entirely. The Free Second Opinion and the written upfront price never expire: they’re part of Clause 1, and Clause 1 is the reason Servo Garage Doors Thornton exists. Call (720) 575-1024 and we’ll tell you exactly what’s running this week.
The 10% senior/military courtesy stacks with any other offer on this page because it’s applied to labor only and it’s a standing courtesy, not a seasonal discount. The other offers run one per visit, because the flat written price under Clause 1 is already the honest number and we don’t play the game of marking it up so it looks like we’re giving more away. If you have a competing written estimate, bring it in and we’ll review it against your job at no charge. Call (720) 575-1024 with specifics and we’ll walk you through the math.
The $50 off emergency service applies to calls placed between 10 PM and 6 AM, seven nights a week, including holidays, anywhere we run trucks in Thornton, Northglenn, Federal Heights, and the surrounding area. The tune-up, second opinion, installation measure, and courtesy discounts are for same-day and scheduled visits. If your door is stuck open at 3 AM, call (720) 575-1024 and you’ll talk to a live person who can dispatch a named technician with an on-the-way text.
The $79 tune-up covers lubrication, bolt torque, track alignment, and a balance check on a standard sectional door with a working opener. If the technician finds a broken roller, a cracked hinge, or a failing spring, you’ll see the failed part in the photo record before anyone quotes a replacement, and the repair is priced separately in writing with your approval required before work proceeds. The tune-up itself is a flat $79, and that number is written on the scope before we start. Call (720) 575-1024 to book your tune-up, and say the word “tune-up” to get the price.
