Sheeted Roll-Up Door Repair

General Door Service provides professional commercial rolling steel and sectional door services for businesses, warehouses, industrial facilities, storefronts, and property managers. Our technicians are factory-trained and equipped to handle everything from repair and maintenance to installation and upgrades — ensuring your doors operate safely, efficiently, and with minimal downtime.

Whether you’re managing a busy warehouse, a distribution center, or a commercial property with heavy use, we deliver reliable results so you can focus on operations.

Sheet doors—or corrugated steel doors—are among the most common roll-up doors in use today. (If your open garage door looks like a rolled-up carpet, chances are you have a sheet door.) The advantage of these doors is they are readily available in many sizes and can last up to 10 years before needing replacement. These doors can be opened and closed by push-pull, hand chain or have an electric motor.

Whether you need one, two or three sections, General Door specializes in the replacement of entire sections of sheet doors. General Door can also evaluate, depending on the amount of damage, if bearings as well as the guides need replacement or straightening. Regardless of what the problem with your sheet door is: If it’s hard to open, if there’s damage to individual panels or the hood—or you would like to add a hood to improve the look of the door—we have options for you.

Once a bottom panel is damaged beyond repair a new one can be ordered and installed in as little as a few days and just a few hours on site.

Replacement Bearings

If your vertical guides have been damaged we have what it takes to get them like new again. Whether they are galvanized steel or heavy duty, it doesn’t matter! We can fix or replace them all. A damaged roll-up door is something that can be easily taken care of and for less than what most people imagine.

Hoods

Did your hood get crunched? Or maybe you would like some of the draft from coming from outside? We can help! Let General Door install that new hood for you.

Wind-locking doors

Has your roll-up door blown out of the opening? Does your area get really high winds? If so you should consider replacement with a wind locking roll-up door. This type of door can handle really high winds and keep your secure when they start acting up. Contact us today for a free estimate!

Insulated Doors

Tired of the summer heat coming into your building? Replace your roll-up door with an insulated one! This can drastically increase the amount of cold air that escapes and the hot air that comes in. Contact us today for a free estimate! An insulated roll-up door is an upgrade that could pay for itself with the AC savings over time.

Weather Seal

A Weather Seal can be an efficient way to help protect the interior of your building from the elements. A proper weather seal helps keep pests, outside contaminants and debris from getting inside your facility. It also helps to keep outside air from getting in and inside air from getting out. A Weather Seal comes in many sizes and styles that fit just about any budget. Contact General Door today and we will send out a trained representative to inspect your facility and help you decide which type of weather seal is right for you and your company.

Frequently Asked Questions

What is the difference between rolling steel and sectional doors?

Rolling steel doors roll up vertically into a coil, saving headroom and providing maximum clear opening. Sectional doors use hinged panels that lift along tracks — offering better insulation and smoother operation.

How often should commercial doors be inspected?

For high-cycle environments (warehouses, docks), we recommend at least annual inspection — and more frequently if usage is heavy or there’s exposure to impact and debris.

What causes commercial doors to bind or jam?

Most jams are from misaligned guides, debris in tracks, worn rollers, or bent slats — each of which can be diagnosed and corrected through professional service.

Can I upgrade my existing door instead of replacing it?

Often yes. Many systems can be retrofitted with improved components, safety systems, or automation — extending life and reducing total cost of ownership.

Do you offer emergency repair services?

Yes. We provide emergency commercial door repair to keep your operation moving when urgent issues occur.
