Iossi Siding & Windows, Inc.
Entire company was started 55 years ago.
"Iossi - SITE UNSEEN. Windows: 4 major problems; no caulk above one of large windows, 2 windows not opening properly (installer said that was the way it was made - yea right) and 1/4 inch gaps on inside that was not caulked, and tried to charge for tempered glass where not needed. All required returns to my house. Flashing inside gutters: not installed where it was 'most' needed. Another return. Unless you are willing to climb latters, etc to inspect their work, go with someone you can trust, even if it's a few more dollars!!"
