We are so sure you’ll be happy with our work on your carpet that we offer a lifetime guarantee on our carpet patch & carpet stretching labor for the life of the carpet. If the repair we did ever came back, we would stand behind the quality of our work by coming back for free to fix the work that we did. Simply contact us and speak with our office staff and we will be happy to come back and fix whatever work we previously worked on for free! Please note: this warranty only applies to labor and not to materials. Kind regards.
