From Our Valued Customers

“We underwent a major kitchen remodel. Troy Weaver from Brookside came to our home and offered great ideas as well as listened intently on what our family needs were in our space. We wanted the wall between our kitchen and dining room taken down and also a cut-out in another wall that would create an open concept. Troy suggested we rent a Pod for the time to store all of our furniture, which cleared everything out for the project to begin. He provided us with a calendar that laid out everything that was happening day to day for 6 weeks. It was truly on spot. Troy handled everything. My husband and I had the fun job of selecting our new appliances, flooring, granite, lighting, doors, trim, and cabinetry. Our kitchen turned out amazing and is so much more functional. We will be calling Brookside again for future projects. They are nice people, stayed on track with a time frame, handled everything professionally, and made sure that every detail was covered and cleaned up on a daily basis. When people come in, the first thing they say is “wow, what a beautiful kitchen!” It’s been a year and I wouldn’t change a thing.”
