"The guys that installed my windows were great. I wasn't worried about leaving them in my house alone while I went to drop my kids off at their activities. They cleaned up after they finished their work. They were able to answer any of my questions. It was a great  experience."

"My wife and I were very pleased with the numerous options of different styles of windows for our house to choose from as we have 24 windows and most of them are quite large. The crew was excellent, the work was done quickly, each employee took care to be neat and clean in my home. It was so nice to have the entire crew of craftsman actually speak English. I could really tell the crew was the highest quality installers in the business. Every house is not perfectly plum, some of our window openings were not always straight. The crew installing our windows had the craftsmanship to make the necessary adjustments for an outstanding fit. My wife who can be very nit picky, was quite impressed with the caulking, it was near perfect!"

"I was a little nervous about the actual construction itself. Once again, my fears were unfounded. The work crew was polite, hard working, and really fast. in less that a week, the job was done. And what a job! The siding is just beautiful it's like some one waved a magic wand and took ten years off the age of my house. And I cannot express how happy I am about not having to paint again"
