I am a Property Manager for a company that manages hundreds of properties throughout SoCal, and we work with many different vendors and contractors in all services and categories. The professionalism from ADUs By Avatar the entire time was unparalleled. They under promise and over deliver to the truest form, something that is often rare in the contracting world. We've done many large projects with them, and just completed a 70K remodel on a townhome in Covina. They did the entire remodel in record time, in fact two weeks sooner than they projected. Their estimates are more transparent on pricing than I am used to seeing, and they actually itemized a lengthy estimate for us that had over 50 items on it. It must have taken hours to put together the estimates, along with the revised estimate we requested after. They were patient, detailed, thorough, trustworthy, affordable, the list goes on. One of my favorite aspects is their 3D imaging, which really helped my team and our client get a great visual of what the right aesthetic pieces would look like for cabinets, doors, flooring, lighting, etc. Highly, highly, highly recommend!!" > > > > B.
