Rated 5 out of 5 by from Grand Openings' team are customer oriented, knowledgable and experienced! Grand Openings did an incredible job installing my windows. I receive compliments from everyone who comes to my home. The pricing was competitive, the project was on time but more importantly the field supervisor and installation team were expert at completing the project in it's entirity.

Rated 5 out of 5 by from I won't use anyone else. I was referred to Grand Openings by a friend who was so pleased with their new windows. The service was above and beyond, very knowledgable and guided me through all my questions. They were fast to schedule the job and finish it. Most everyone I know uses them for their projects. And all of my guests love my front door!!!

Rated 5 out of 5 by from Very professional and a pleasure to work with. After getting quotes from several window and door companies, we went with Grand Openings. Not only did they come out when the said they would, they knew exactly what they were talking about. They were very knowledgeable about the different styles and what would fit our needs and stay within our budget. The workers were always on time. This company was very professional with every step of our order. I would defiantly use them again and I highly recommend them for any door or window needs.

Rated 5 out of 5 by from A wonderful company to deal with. Ken and Judy were very helpful and knowledgable. They helped me design my window replacement and taught us more then we ever expected to learn about windows, and there really is a difference between window companies. We decided to go with the Milgard Tuscany windows and it was the right choice. We would highly recommend this company to anyone looking to replace windows in their home.

Rated 5 out of 5 by from The best of the best!! We had Grand Openings replace a few doors and windows in our home. I have nothing negative to say about this company. They were professional, knowledgeable, and very friendly. They showed up on time, did great work, and left my house clean! They are competitively priced and a great family business. I would highly recommend them to anyone looking to invest in doors or windows!
