Addition Types
Home Addition Options for Middleton Homeowners

Luiz has done many projects, from major renovations to minor repairs, for us in multiple homes over the last ten years. He and his company always do excellent and timely work. I would recommend him any time.
We used DeFaria Construction twice, once for a gut remodel of a condo unit and the other for a basement and garage upgrade. They are very professional, reasonably priced, do a great job, stick to their timelines and leave the work area totally clean at the end of every day. I highly recommend Luiz…
My husband and I are so grateful for the beautiful work Luis did to get our home move-in ready. We had a newborn and a tight move-in window, and Luis went above and beyond to get everything done in time. He helped us with multiple projects including building a gate, repairing walls/doors…
