I'd recommend Tim and the L&L team to everyone. The work is top quality, and they deliver a personal experience at a great value. Tim was insightful and helpful when I was choosing the best product for my needs. Mike the installer worked quickly, was personable professional and was meticulous about the work - left the property clean afterwards. The service before, throughout and after the project was top notch. Thank you Tim and Mike.
