90-Day Done Right Promise - if it's not done right, we make it right

What Our Promise Actually Means

If the work isn’t right, we come back and fix it – no charge, no argument, nothing you have to sign or prove. That’s the whole promise. It’s written on every job ticket, it runs for 90 days from the date of service, and it’s backed by Mainspring Garage Door Co. and the Keystone family together. You don’t file a claim. You don’t navigate a phone tree. You call the same number you called the first time, a real person picks up, and we schedule a return visit. That’s it. We’ve been doing this since 1984, and in our experience, a guarantee that requires a homeowner to fight for it isn’t a guarantee. It’s fine print. Ours isn’t.

Why We Answer Fast, Everywhere

A one-truck operation is a fine thing – until it’s 10 p.m. on a Sunday and that truck is parked in someone else’s driveway. What a national brand with local crews across 35 states can do is keep the phone staffed around the clock and put a technician on the road from somewhere close to you, not somewhere far from you.

We’ve built the dispatch side of this carefully. Technicians run stocked trucks – springs, cables, openers, the parts that fail most often are already on board before the call comes in. That’s how most jobs get done in a single visit. The response window we’ve committed to isn’t a marketing number; it’s what our crews are held to every shift. For emergencies, we aim to have a technician on your property within four hours. For everything else, same day or next day is the standard, not the exception. We don’t overbook to look available. We staff to be available.

How We Make It Right

You Tell Us

Call (844) 755-5838 and tell us what’s wrong. You don’t need the job number in front of you or a written description of the defect. Tell us what the door is doing and when we did the work, and that’s enough. A live person takes the call and starts the return visit from there.

We Come Back Out

We schedule a return visit at a time that works for you – same crew when possible, a qualified technician either way. There’s no separate dispatch fee, no inspection charge, and no conversation about whether the problem falls within the promise. If it’s within 90 days of our work, we treat it as our responsibility until proven otherwise.

We Fix It

The technician corrects the issue on the return visit. Same standard as the first visit: upfront diagnosis, the right parts already on the truck for most common follow-up work, and the job done to the same quality that should have been there the first time. The K.E.Y.S. values code our technicians train under puts it plainly: the 400th job gets the care of the first.

You Sign Off

When the door is right, you say so – and that’s the end of it. No survey, no review request standing between you and a closed job. If for any reason the return visit doesn’t resolve it, you call again. The 90 days doesn’t restart, but our obligation to get it right doesn’t expire either. We’re not looking for a way out. We’re looking to close the loop.

What Stands Behind the Promise

A written guarantee is only as solid as the people and systems behind it. Here’s what we’ve actually built.

Every technician is background-checked before they put on a Mainspring uniform – not as a checkbox, but because our customers are letting someone into their home. The technicians are trained as journeymen under the K.E.Y.S. values code: Krafted right – proper materials, no shortcuts; Every time – consistent work regardless of the job number; Your home first – we work the way we’d work in a family member’s house; Standing behind it – if it’s not right, we come back.

Pricing is flat and stated before any work starts. No hourly rates. No subscriptions. No financing products. The number you agree to is the number on the bill. Parts come from factory-familiar stock – we work on LiftMaster, Chamberlain, Genie, Clopay, Amarr, Wayne Dalton, Craftsman, and Raynor, and we carry what those systems need.

And behind Mainspring stands Keystone. The family guarantee – The Keystone Standard – is co-signed on this promise. When Keystone puts its name on a company, it stands behind the crew that shows up at your door.

Ask Us to Prove It

Call (844) 755-5838 and a real person will answer – day, night, weekend, or holiday. If you’d rather book online, you can do that too. The full terms of the 90-Day Done Right Promise are on our Terms page. Read them. We wrote them to be read.
