Ray's team did an AMAZING job transforming our 90s hallway bathroom into a modern-day zen haven!! We received bids from five different construction companies before deciding to go with CRIBA. Ray's quote was reasonable, had raving reviews, and overall he just feels like an honest and sincere guy. We are really glad that we made the right choice! We appreciate the crew – Nino, Alex, Noah, and Gerardo. Everyone is nice and easy to work with. They are talented and took time with the design details and were super patient with my changes and adjustments (which I appreciate most!!). Remodeling is a stressful process, given that we might be living with the permanent changes for decades. I am really grateful the crew always made sure I liked the work.

We highly recommend Ray and his team and look forward to when we do the family room and master bathroom next! Thank you CRIBA!! 🙂

P.S. fave material sources:
-Commercial grade vinyl wallpaper from Mayflowerwallpaper.com
-Integrated Corian countertop from Bay Custom Countertops
-Recessed ceiling lights with full-on and back-lit options from Amazon
-Porcelain wood tiles from Home Depot and wall tiles from Floor & Decor

I recently hired Construction Remodeling in BayArea for a full bathroom remodel, and I couldn’t be happier with the results. From the beginning, Ray and his team were professional, communicative, and incredibly detail-oriented. They helped me refine my design ideas and ensured everything was done on time and within budget. The craftsmanship is top-notch — the tile work, fixtures, and finishes all look stunning. What impressed me most was their cleanliness and respect for my home throughout the process. I highly recommend them to anyone considering a renovation — they deliver quality work with a personal touch.

We recently had our kitchen remodeled and couldn't be happier with the results! From start to finish, Ray and team was professional, punctual, and extremely detail-oriented. He listened carefully to what we wanted, offered helpful suggestions, and delivered exactly as promised -- all at a very reasonable price compared to other quotes we received. Every corner, cabinet was installed with great precision, and they stayed on schedule throughout the project. It's rare to find a contractor who combines quality work with reliability, but this team absolutely delivered. Highly recommend if you're looking for an stress-free, beautifully done kitchen renovation!"
