Warranty

We stand behind the products we sell. The manufacturers we partner with back their windows and doors with some of the strongest warranties in the industry.

Product Warranties

Mid-West Door & Window carries two of the industry's most trusted product lines — Lincoln Windows and MI Windows and Doors. Both manufacturers are committed to quality and stand behind their products with comprehensive warranty coverage. Below you'll find an overview of each warranty program along with a link to the full details on the manufacturer's website.

Lincoln Windows

Lincoln is dedicated to producing the highest quality windows and patio doors on the market and backs their products with a very strong warranty. The current warranty covers products manufactured May 2021 and beyond, with documentation for previous warranty periods also available.

Lincoln Warranty Service Centers can inspect, order parts, and repair or replace damaged materials — whether they are under warranty or out of warranty — and assist with installation of replacement materials. As an authorized Lincoln dealer, Mid-West Door & Window is your local starting point for any warranty need.

To get started, it helps to have your original bill of sale and your glass or warranty code on hand. Glass codes can be found on the spacer channel between the panes (pre-2000 products) or etched in a corner of the glass (post-2000 products). Lincoln's warranty support line is also available at 1-800-967-2461.
