When we decided to get a Four Season Room we got quotes from several different companies. In talking to a representative of Andresen Sunrooms of Granger I liked how they build the room and the cost. I had a few questions so I went to their office and I talked to Mark Andresen the owner a few times. He was very helpful and answered my questions. When the room was being built the crew supervisor Dave explained every stage of the build. I am very happy with the finished product and have nothing but complements from family and friends. I would highly recommend Andresen Sunrooms of Granger.

Wonderful experience for my elderly mother! Several years ago, my mother wanted a covered patio so she could go outside in all weather. She was treated with respect and honesty. She was absolutely thrilled with the result and cost. I would recommend to anyone wanting to add an inside/outside space for their home.

Mark and his staff made this process A+ from start to finish! No pressure and easy going. We designed our 10X15 room with their guidance. We love our three season room; it is high quality and durable. We use it a lot. Definitely recommend this company for Southwest Michigan and beyond.

We just had an Awning installed on our home from Andresen Sunrooms and it looks great! We love the color and the way it looks on our home. The installation was fast and professional.

We have had 3 sunroom installations with Mark and have been so happy with the results. Mark is knowledgeable about, and was extremely helpful with, designing the perfect sunroom for us. His team is also knowledgeable and professional, taking great care in the preparation and installation process. The patio enclosure product itself is well constructed and we have never had any issues in all the years of frequent use. We would not hesitate to work with Mark and his team again in the future or recommend them to anyone looking to add a sunroom.

Absolutely a non-pressure sales transaction! We purchased an awning and are planning to go back for windows :)

Built two sunrooms with Andresen Sunrooms and was extremely satisfied with the product and installation.

Great craftsmanship, love my space.

Always a pleasure
