What sliding door customers wrote

I had BMR Windows install two sliding glass doors. They were extremely professional. … It took 4 hours, maybe, and they were done!

BMR windows recently installed a basement sliding door. The process is so seamless, Michael visited the house and did some measurements, presented several options and recommended the best one within our budget.

BMR Windows installed my deck and porch sliding doors a few days ago. I highly recommend this company because the doors were installed quickly and professionally.
