We needed one egress window & a sliding glass door replaced and living in MN the big name is Andersen. Their commercials say all stages will be done by Renewal employees-it wasn't. First our window was not ordered properly so we had to deal with 2 installs weeks apart. Which forced us to move our staining appointment out a month. The egress window (which was installed by people with Andersen shirts) was installed with the wrong hardware, discovered by our city inspector. So they had to fix then the inspector had to come out again. The sliding glass door was installed by a subcontractor with no supervision by Andersen. Many issues: main frame piece had a huge gouge in it, they came back to fix; screw in top frame piece was put in wrong spot so stainers could not properly stain-project manager came to fix then stainers were pushed out another week; after staining the paper tape was removed around the frame we discovered the frame was gaping 1-2 inches from wall. When reported Andersen moved us to the service department instead of project dept even though we were still dealing with the initial install issues. We had to wait another 3 weeks for them to come out AND I had to coordinate stainers return to finish once again. Since report of frame gap no one has contacted us, checked in on status. They even sent us a completion survey even though we still weren't complete. I gave 2 stars for quality of product but installation & customer service are awful. They are high $$ due to their claims of superior service & attention to details and customer needs but they are NOT WORTH IT mainly because those are false claims, at least in my experience. It's been almost 3 months & we still aren't complete. I still can't schedule my window treatment install-pushed back 3 times already.
