Why South Dakota Homeowners Choose Mainspring Garage Door Co.

When you invite us into your home in South Dakota, you are getting more than just a repair technician. You are getting a team that has been working in this trade for over four decades. We know that garage doors are complex, heavy systems, and we treat your home with the same care we would use in our own mother’s house. Our technicians are background-checked, uniformed, and factory-familiar with all major brands including LiftMaster, Chamberlain, Genie, Clopay, Amarr, Wayne Dalton, Craftsman, and Raynor. Because we keep our trucks stocked with springs, cables, and openers, we complete most jobs in a single visit, meaning you do not have to wait on parts.

We do not believe in hidden fees or surprises on the bill. Before we turn a single wrench, we provide a clear, flat price so you know exactly what you are paying. If you have been burned by contractors in the past, you will appreciate our straightforward approach. We answer the phone 24/7, including nights, weekends, and holidays, because we know garage door problems do not wait for business hours. We also provide a $50 discount on any repair over $250, a $89 seasonal tune-up to prevent winter breakdowns, and a permanent 5% discount for veterans and seniors across South Dakota. If you have a written estimate from another company that you are unsure about, call us for a free second opinion.

A note on safety: Garage door springs and cables are under extreme tension and can cause severe injury if mishandled. Please do not attempt to adjust or replace these components yourself. Our trained journeymen are equipped with the specific tools and experience to handle this dangerous work safely.
