"We had several contractors give us estimates and Ani of LGC was the best. She was knowledgeable, professional and not pushy at all. My husband and I felt very comfortable with her and it didnâ t take us long to choose her. She helped with the design, locating materials and also helped us save money. The workers arrived on time, put in a full dayâ s work and did an amazing job for us. What started as a primary bathroom remodel turned into primary bedroom, bathroom and master closet redo, flooring to most of our house and two patio redos. We felt comfortable with the entire process from start to finish. Ani and her crew kept us informed and helped with giving us other options that we didnâ t even think of. In a few weeks they will put in a beam in our family room. Iâ m very excited. The entire crew were very professional, knowledgeable, neat and cleaned up afterwards. We will definitely use them again. We couldnâ t be more happier with the choice we made. It was the RIGHT one."
