I would like to thank Brandon, Callum, and Gary who where all very professional and very courteous. They made sure to put down mats all over, so as not to dirty the carpet or the wood floor. They were very professional in the way they went about their work. The quality of the work was excellent and beyond reproach. They even went overboard to help me with another matter that wasn’t even part of their work detail. I would recommend them all very highly.

I would highly recommend this company. We had been having problem with another construction company. Lifetime was so professional and respectful of our home and property. They did a fabulous job on our siding answering all questions and keeping us in the loop throughout the process. They made me believe in quality work and workmanship again. If you are in need of siding make sure to call Lifetime.
