CVS did our lanai almost 3 years ago in tinted acrylic sliders and we love it. Very happy with having another room that doesn't get rained into or dusty. We then added Munn's ductless A/C and heat made by Mitsubishi and we couldn't be happier. Can't comment on how long the job took as we were back in Massachusetts at the time but I can say the sliders look fantastic 3 years post install. Village of Hadley.
We had our lanie enclosed by them, not really happy with it. I wouldn't use them again. A 4 or 5 day job ended up taking 6 weeks. They wouldn't show up when they were supposed to... They use only Subs. so they can't really control the work..
