Compare renovation companies by reviewing their relevant project experience, design process, permitting capabilities, construction coordination, communication style, and approach to materials and sustainability. It is also useful to determine whether you will work with one integrated practice or several disconnected providers. Ask how the company guides decisions from initial concepts through construction, and whether its portfolio reflects the character and complexity of your home.
