We had Lifetime install new fire resistant siding and it is awesome! We had an issue with damage to our aluminum decking and the project manager Marty stayed with us through the process of getting it repaired. The crew that did the deck repair (Jose & his brother) were great and it is better than it was before! We recommend Lifetime to anyone looking for new siding! They truly warranty their work.

Lifetime Windows far exceeded my expectations, they did an outstanding job! I had all the windows replaced in my townhome in Frisco, and not only was the quality of their product far superior to their competition, they were reliable, diligent, communicative and professional. I cannot recommend them more strongly, I was thrilled with the process and the results!
