Garage Door Specials in Alamo Heights, TX
We’re not big on gimmicks. Call (830) 364-5701 and a live person will pick up, day or night, and tell you exactly what’s running right now. Our standing offers have been around for years because they represent what we actually do: charge a square price, show up when we say, and stand behind the work. No rotating “limited-time” codes, no bait-and-switch. Just honest value for Alamo Heights homeowners who need a garage door that works.
Current Offers
$50 Off Any Repair Over $250
Most spring replacements, cable repairs, and opener fixes in Alamo Heights fall into this range, especially on heavier Clopay or Wayne Dalton doors common in the older ranch homes off Broadway and Vance Jackson. If your repair quote comes to $250 or more, we’ll take $50 off the total before you pay a dime.
Valid through December 31, 2026. Mention this offer when you call (830) 364-5701.
Free Second Opinion on Any Written Estimate
Got a quote from another company that feels high? Bring us the written estimate and we’ll diagnose the problem ourselves, no charge. We’ve been at this since 1984, and we’ve seen plenty of Alamo Heights homeowners quoted for full door replacements when a $200 spring fix would have done the job.
Valid through December 31, 2026. Mention this offer when you call (830) 364-5701.
$89 Seasonal Tune-Up
Alamo Heights sits on the Balcones Escarpment, where summer heat hits 105 degrees and winter northers drop temperatures fast. That thermal swing beats up springs, rollers, and weatherstripping. Our seasonal tune-up includes lubrication, balance check, safety sensor alignment, and hardware tightening. Catch a worn cable before it snaps on a Monday morning.
Valid through December 31, 2026. Mention this offer when you call (830) 364-5701.
Permanent 5% Senior & Veteran Discount
This isn’t a Veterans Day promotion that disappears November 12. If you’re 65 or older, or you’ve served in the military, you get 5% off every job, every time, no cap. We’ve got customers in Terrell Hills and Olmos Park who’ve used this on three different houses over fifteen years. The discount stays.
Valid through December 31, 2026. Mention this offer when you call (830) 364-5701.
How to Redeem
Step 1: Call and mention the offer. Dial (830) 364-5701. A live person answers, 24/7. Tell them which special you’re calling about.
Step 2: Book the visit. We’ll find a window that works, confirm the address in Alamo Heights, and give you a two-hour arrival window. No “sometime between 8 and 5.”
Step 3: Present at time of service. Our technician applies the discount to your written, upfront quote before any work begins. The price you agree to is the price on the invoice. No surprises on the bill.
What These Offers Actually Mean
We’ve kept the same four specials running for years because they cover what people actually need. The $50 repair discount handles the most common call we get: a broken torsion spring on a two-car door in a neighborhood like Alamo Heights proper, where homes built in the 1950s and 60s still have original wood doors that weigh 200 pounds or more. The free second opinion exists because we’ve rescued too many homeowners from unnecessary full-replacement quotes. The $89 tune-up pays for itself if it prevents one emergency call during a July heat wave when the garage is 120 degrees inside. And the senior-veteran discount is permanent because it’s the right thing to do, not a marketing hook.
Every job, special or not, comes with our 90-Day Done Right Promise in writing. If something isn’t right, we come back. No paperwork to file, no argument, no charge. Carl Dutton put that in place when he took over day-to-day operations, and it’s outlasted three recessions and a pandemic.
Frequently Asked Questions
Yes. We stack the 5% discount on top of the $50 off, so a $300 repair becomes $237.50 before tax. Call (830) 364-5701 and we’ll run the numbers while you’re on the phone.
The tune-up covers labor for adjustments, lubrication, and safety checks. If we find a cracked spring or frayed cable, we’ll show you the damage and quote the replacement separately, with the $50 discount applied if you’re over $250. You’re free to decline any additional work. No pressure.
Any printed or emailed quote from another garage door company with their letterhead, your name, and a price. Bring it or email it ahead. We’ll do our own inspection and tell you if the diagnosis matches. Sometimes it does, sometimes it doesn’t. Either way, you know.
The $50 repair discount applies to repair work only. For new installations, we provide a free measure and written quote with no deposit required. The senior and veteran 5% discount does apply to installations. Call (830) 364-5701 to schedule a measure.
No. The flat price is stated before any work begins. If we find something unexpected, we stop and explain it. You approve the new quote or you don’t. We’ve had customers in Alamo Heights tell us that’s why they keep our magnet on their fridge.
Why We Don’t Do Flash Sales
Carl Dutton started answering phones here in 1984, back when Alamo Heights was mostly retired military and old San Antonio families. The business grew by showing up, doing the work right, and coming back if it wasn’t. Flash sales train customers to wait for a discount instead of calling when the door is actually broken. We’d rather you call today because your spring snapped, not because a countdown clock expires at midnight. These four offers have been steady for years, and they’ll stay steady until something fundamental changes about how we operate. So far, nothing has.
Our trucks carry springs, cables, rollers, and openers for LiftMaster, Chamberlain, Genie, Clopay, Amarr, Wayne Dalton, Craftsman, and Raynor. Most jobs finish in one visit. Our technicians are background-checked, uniformed, and trained under our K.E.Y.S. code: Krafted right, Every time, Your home first, Standing behind it.
Call (830) 364-5701 anytime. A live person picks up.
