Free Second Opinion on Any Written Estimate
Got another company’s quote in hand? Bring it to us and we’ll review it at no charge, no obligation.

Permanent 5% Senior & Veteran Discount
This one doesn’t expire. Active duty, veterans, and seniors 65 and older get 5% off every job, every day, stacked with any other standing offer if the math works.

90-Day Done Right Promise - Included on Every Job
Not a coupon, but worth knowing: every repair and installation we complete in Shavano Park carries our written guarantee. If it’s not done right, we come back and make it right.

Mention this offer when you call (830) 224-4217.
How to Redeem
Step 1: Call and mention the offer. A live person answers at (830) 224-4217, 24/7. Tell them which special you’re using so we note it on your ticket.
Step 2: Book your visit. We’ll give you a window and a heads-up call when our technician is en route. Most repairs in Shavano Park are completed in a single visit because our trucks carry springs, cables, and openers.
Step 3: Present at time of service. The technician confirms the discount before any work begins. Your price is locked. No surprises on the bill.
What These Offers Don’t Cover
We don’t play the fine-print game, but we’re clear about boundaries. These specials apply to residential garage door service in Shavano Park and our surrounding 13 communities. They don’t stack with one another except where noted (the senior/veteran discount applies alongside other offers). Commercial rolling steel or fire-rated door work is quoted separately. And we don’t honor competitor coupons - our pricing is already flat and upfront, so there’s no hidden margin to carve from.
Why We Price This Way
Carl Dutton started Mainspring Garage Door Co. in 1984, and he’s still answering the phone some mornings. The name comes from the mainspring, the coil that carries a door’s entire weight. That’s the part we respect: the thing doing the real work, hidden from view, that everything else depends on.
In Shavano Park, we see a lot of doors that were installed in the 1990s building boom and are hitting their second or third spring cycle. The Hill Country’s temperature swings - 40 degrees in a day isn’t unusual - stress metal in ways that coastal climates don’t. We price for the long haul because we’d rather see you every few years for a tune-up than once for a cheap fix that fails in six months.
Our technicians are journeymen-trained under our K.E.Y.S. code: Krafted right, Every time, Your home first, Standing behind it. They’re background-checked, uniformed, and factory-familiar with LiftMaster, Chamberlain, Genie, Clopay, Amarr, Wayne Dalton, Craftsman, and Raynor. They carry the parts. They quote the price before turning a wrench. And they leave the written 90-Day Done Right Promise on every job.
Common Questions About Our Offers
Can I combine the $50 repair discount with the senior discount?
Yes. If your repair exceeds $250 and you qualify for the senior or veteran discount, both apply. We’ll show you the math before we start.
Do I need to print a coupon?
No. Just mention the offer when you call (830) 224-4217. We track it by your phone number and address.
What if my repair is under $250?
You’ll still get the upfront flat rate and the Done Right Promise. The $50 discount kicks in once the job crosses that threshold.
Is the tune-up really $89, or are there add-ons?
$89 covers the full inspection and adjustment. If we find a part that needs replacement, we’ll quote it separately and wait for your go-ahead. No surprises on the bill.
Does the free second opinion apply to Mainspring’s own estimates?
The second opinion is for reviewing another company’s written quote. Our own estimates are already itemized and flat-rated, so there’s nothing to second-guess.
Ready to Book?
Call (830) 224-4217 any time. Nights, weekends, holidays - a live person picks up. We’ll be there when we say, we’ll quote before we work, and we’ll stand behind it.
