GARAGE DOORS & OPENERS

Pole barns typically use overhead sectional doors, either non-insulated (nominal 24-gauge raised short panel steel) or insulated (R-6.7 rated polystyrene between 26-gauge substrate). Both come with torsion springs and a 12" radius track system. For Minnesota winters, insulated doors are strongly recommended to manage interior temperature and reduce energy costs. Custom colors, windows, and panel designs are available on all door types.

Yes. Sherman Buildings installs new overhead sectional doors on existing pole barns, residential garages, and commercial shops — whether the building was originally built by Sherman or by another contractor. We can also re-frame a rough opening to accept a larger door if you are upgrading from a smaller or older unit.

Both. We install and service single-bay residential overhead doors, multi-bay shop doors on farm pole barns, and larger commercial overhead doors on shops, warehouses, and storage facilities. Commercial-duty openers and high-cycle torsion springs are used where the door is opened dozens of times per day.

Opener sizing depends on door weight, door width, and how often the door cycles. Heavier insulated doors and taller doors need a higher-horsepower unit, and commercial applications typically use a jackshaft or commercial-duty opener instead of a residential belt-drive. We match the opener to the specific door and use case during the quote so the hardware has headroom rather than running at its limit.

We recommend a professional inspection and tune-up at least once a year. Regular maintenance includes lubricating hinges, rollers, and springs; checking cable tension; testing the auto-reverse safety function; and inspecting weather sealing. In Minnesota's climate, spring and fall are ideal times — before extreme heat and before the deep freeze — to catch any issues early and keep the door operating safely.

Common repairs include broken torsion springs, frayed or snapped cables, damaged panels, bent tracks, worn rollers and hinges, weather-seal replacement, and opener issues (logic-board failures, sensor alignment, drive-chain or belt replacement). Broken springs are the most frequent call, especially after the first hard freeze, and should only be serviced by a trained technician because of the stored energy involved.

Most standard single-bay installations on a pole barn are completed in a single day. Multi-bay shop installations, custom-framed openings, or jobs that include opener programming typically run one to two days. We schedule around your work week and give you a clear start and end window before the crew arrives.

Consider replacement when you are facing multiple failures at once — panels, springs, and rollers together — when an un-insulated door is costing you heating dollars on a heated shop, or when the door is more than 20–25 years old and parts are hard to source. If the opener is also dated, bundling a new door and opener is usually more cost-effective than piecemeal repairs over several seasons.

Yes — especially in Minnesota. Insulated doors significantly reduce heat loss in winter and keep your barn cooler in summer, which translates to lower heating and cooling costs over time. They also reduce noise, are more dent-resistant than non-insulated doors, and generally have a longer service life. If you plan to heat or work in your pole barn, insulated doors are one of the best investments you can make.

Yes. Sherman Buildings offers a wide selection of colors and panel designs to complement the steel siding and roofing on your pole barn. From raised short panels to long panels and contemporary flush designs, we can match or coordinate with your building's existing color scheme. Custom colors are available as an upgrade on most door lines.

We install and service garage doors across all of Minnesota and Northwest Wisconsin, with primary scheduling within approximately 200 miles of our Mora, MN headquarters. That includes the Twin Cities exurban area, central Minnesota, the Brainerd lakes, Duluth, Hinckley, Sandstone, and the Polk/Burnett/Barron/Washburn/Douglas county region of Wisconsin.
