We want to ensure that the process of installing your Therma-Tru entryway and patio doors are as easy and stress-free as choosing your door.
Most of our entry and patio doors come pre-hung so that you can simply remove them from the packaging ready to install. You'll find easy-to-follow instructions included, as well as the online video and print guides designed for further assistance.
