  • Our experience with Casa Sisu was a 10 out of 10! Becca and Ashley helped us transform a spare bedroom into a home office and we are thrilled with how it turned out. They know their stuff and made the process easy and enjoyable. I very highly recommend them.

  • I loved working with Becca and Ashley on our kitchen and bathroom remodel. They helped me hone my vision and style and guided me flawlessly throughout the process. They have excellent taste and attention to detail plus a strong understanding of construction - all of our other contractors were impressed with their cross functional skillset and professionalism. I can't wait to work with them again and highly recommend them.
