We don’t just build the best doors in the industry; we stand by them. 

In addition to technically sound and well-engineered products, we also believe in selling peace of mind. Every door we sell comes with an industry-leading warranty that’s unique to that door.

The Distributor of Overhead Door Corporation products, whose name appears below (“Seller”) warrants to the original purchaser of the Legacy® 650 (Model 1029 and 1029H) & Legacy® 850 (Model 2029 and 2029H) garage door openers (“Product”), subject to all of the terms and conditions hereof, that the Product and all components thereof will be free from defects in materials and workmanship for the following period(s) of time, measured from the date of installation: • MOTOR/GEARBOX – Seller warrants the motor for the FIVE (5) YEARS for Legacy® 650 • MOTOR/GEARBOX – Seller warrants the motor for the TEN (10) YEARS for Legacy® 850 • BELT – Seller warrants the belt for a period of FIFTEEN (15) YEARS. • CHAIN- Seller warrants the chain for a period of FIVE (5) YEARS. • PARTS – Seller warrants all other parts and components for a period of ONE (1) YEAR. • ACCESSORIES – Seller warrants all accessories for a period of ONE (1) YEAR Seller’s obligation under this warranty is specifically limited to repairing or replacing, at its option, the Product or any part thereof which is determined by Seller to be defective during the applicable warranty period. Any labor charges are excluded and will be the responsibility of the purchaser. This warranty gives you specific legal rights, and you may also have other rights which vary from state to state. This warranty is made to the original purchaser of the Product only, and is not transferable or assignable. This warranty applies only to Product installed in a residential or other non-commercial application. It does not cover any Product installed in commercial or industrial building applications. This warranty does not apply to any unauthorized alteration or repair of the Product, or to any Product or component which has been damaged or deteriorated due to misuse, abuse, neglect, accident, failure to provide necessary maintenance, normal wear and tear, or acts of God or any other cause beyond the reasonable control of Seller, and does not cover batteries, or repairs or maintenance to door components. ALL EXPRESS AND IMPLIED WARRANTIES FOR THE PRODUCT, INCLUDING BUT NOT LIMITED TO ANY IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE, ARE LIMITED IN TIME TO THE APPLICABLE WARRANTY PERIOD REFLECTED ABOVE. NO WARRANTIES, WHETHER EXPRESS OR IMPLIED, WILL APPLY AFTER THE LIMITED WARRANTY PERIOD HAS EXPIRED. Some states do not allow limitations on how long an implied warranty lasts, so the above limitation may not apply to you. IN NO EVENT SHALL OVERHEAD DOOR CORPORATION BE RESPONSIBLE FOR, OR LIABLE TO ANYONE FOR, SPECIAL, INDIRECT, COLLATERAL, PUNITIVE, INCIDENTAL OR CONSEQUENTIAL DAMAGES, even if Overhead Door Corporation has been advised of the possibility of such damages. Such excluded damages include, but are not limited to, loss of use, cost of any substitute product, or other similar indirect financial loss. Some states do not allow the exclusion or limitation of incidental or consequential damages, so the above limitation or exclusion may not apply to you. Claims under this warranty must be made promptly after discovery, within the applicable warranty period and in writing to the Seller whose name and address appear below. The Purchaser must allow Seller a reasonable opportunity to inspect any product claimed to be defective prior to removal or any alteration of its condition. Proof of purchase and/or the installation date, and identification as the original purchaser may be required. Upon determination by Seller that the Product or any part thereof is defective during the applicable warranty period, Seller will supply the purchaser with replacement parts or, at its option, a replacement Product (shipping and handling of any replacement part(s) or replacement Product also at purchaser’s expense). Seller may use new or reconditioned parts, or a new or reconditioned Product of the same or similar design. There are no established informal dispute resolution procedures of the type described in the Magnuson-Moss Warranty Act.
