Not happy with our experience, the installation process started smooth but when they installed the incorrect handle set it left a mark on the new door. We had to wait for a touchup kit, after touching the door up it just didn't look right. We had a tech come out, 2 weeks later, he tried to do a touch up and now I wished we never did the door. $4600 this is the result of our front door installation (see photo). Wouldn't recommended based on our experience.

Alexander Company is the best -- not only for doors and windows -- but the customer service and quality. I made an appointment for the initial contact and Walter showed up on time, took measurements within minutes, and showed appropriate catalogs taking into consideration what I wanted. He even saved me money by pointing out comparisons. He was honest as to how long it would take to build the door.
Their installation gentleman, Jose, is absolutely the best. He initially set up a wall tent to protect our house during the installation. He is meticulous and takes pride in his work. He's currently teaching a younger worker to be exact, careful, and enjoy the process. I noticed that Jose reviewed his work from gauging the size of trim needed to caulking. He even adjusted the height of the peephole in the door to accommodate the steep stairs. He truly is a master. I'm so glad I went through Alexander Company to get exactly what I wanted. I mean I only buy a door once every 20 or 30 years and this one will last.

Jeff and team did an amazing job replacing our windows and two sliding doors. Our job required some 'extra' effort, which included bringing in scaffolding and removing exterior stucco to allow for new construction installation. Jeff did a great job communicating expectations around material delivery, costs etc. The new windows look great. I highly recommend Alexander Company and their team.

We had a wonderful experience. The team that came to replace the windows were polite, respectful and friendly. They took the time to clean up the area that they were working around. They also made sure that I was able to open/close the windows. I would recommend them to everybody that I know.
