Century Windows & Doors

We had to replace kitchen window and dining room window and sliding balcony door. We live an in old condo building with floor to ceiling aluminum windows that were 40 years old so they lost air tightness and were bleeding heat during winter time. Sliding door was almost impossible to move despite constant WD-40.
Century Windows & Doors did a superb job - we got band new plastic windows, no air leaks, door's very easy to slide. Century's installation was very professional even though I live in a non-standard building and they had to go out of their way to dislodge and remove my old window frames. Overall I am very satisfied!
