Thermacore® Warranty Information

Learn More About the Thermacore Warranty

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.

Thermacore® Collection Garage Door Limited Warranty The Distributor of Overhead Door Corporation products whose name appears below (“Seller”) warrants to the original purchaser of the Thermacore® garage door model below (the “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 periods of time, measured from the date of installation:

• Seller warrants the door sections against splitting, cracking, or deterioration due to rusting through for the period of time listed below: Model 5740 – (190 Series) – Limited lifetime* Model 5720 – (290 Series) – Twenty (20) years Model 5760 – (490 Series) – Limited lifetime* TWO (2) YEARS against peeling or color fade of finish on Product sections with Black finish, Walnut, Mission Oak or Golden Oak wood grain finish which materially alters the color of the Product and cannot be remedied by cleaning with the recommended solution.

• Seller warrants the Product door sections from delamination of the polyurethane foam from the steel skins of the panel for a period of ten (10) years.

• Seller warrants all other components of the Product for a period of one (1) year.

*Limited lifetime shall mean as long as the original purchaser owns, and the Product remains installed in, the home in which the Product is originally installed.

Seller’s obligation under this warranty is specifically limited to repairing or replacing, at its option, any part which is determined by Seller to be defective during the applicable warranty period. Seller’s repair or replacement labor is included for a period of one (1) year form the date of purchase. After that, 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, neglect, accident, failure to provide necessary maintenance, normal wear and tear, failure to comply with Product painting instructions, or acts of God or any other cause beyond the reasonable control of Seller. This warranty does not cover any damage or deterioration caused by exposure to salt water, chemical fumes or other corrosive or aggressive environments, whether naturally occurring or man-made, including, but not limited to, environments with a high degree of humidity, sand, dirt or grease. Product repaired or replaced under this warranty shall receive a factory original finish. This warranty does not cover the costs to repaint Product. Products with Black, Dark Brown or Wood Grain finishes are susceptible to thermal bowing as described in DASMA (Door & Access Systems Manufacturers Association) Technical Data Sheet 185; Except as expressly provided in this warranty, Seller does not warrant Products with these finishes against warping, rubbing or other issues associated with thermal bowing and strongly recommends against selecting such finishes for Products which are to be installed in areas that experience high heat and/or high UV conditions, such as the Southwest United States, Central America, and the Middle East.

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 the purchase and /or installation date and identification as the original purchaser, may be required. There are no established informal dispute resolution procedures of the type described in the Magnuson-Moss Warranty Act.
