We had a great experience with Window Seal West. Sergey, their salesperson, was great from the very start of our project: down to earth, very knowledgeable, polite and never pushy. He was very patient, as my husband and I were trying to figure out the type of windows we preferred for two bedrooms in our rental property to replace the old ones. He was very easy to get hold of when we had more questions or needed clarifications. The installing crew did an outstanding job. They were top notch professionals who were friendly, prompt, and pleasant people to be around. The windows looks fabulous, the quality and workmanship are great and the price was very reasonable. Thanks to all the people who were involved in our project! Two thumbs up to you, guys. We will absolutely use you again.
