We were looking for a company that was transparent, responsive and did high quality jobs. We heard about ASL Remodeling through a family friend for a property of ours in the Bay Area. We needed to do a full home renovation. Yoni came to meet us, he was so knowledgeable and guided us through the entire process. All the work was completed while we were outside of the country, so trust and communication were crucial. They were on top of everything. They kept us informed at every stage. They were very professional and we are so happy with the final result. Grateful to ASL Remodeling, looking forward to working with them again in the future.
ASL Remodeling did a great job with a whole home remodel for us. The project stayed on track and on budget (well we choose to add a few things along the way). We did flooring, doors, 2 fireplaces, a whole kitchen, stairs, railing, etc… and we are happy with how everything turned out. ASL also did a great job helping us out with unexpected fixes when winter weather threw us some curveballs. We’re looking forward to working with ASL on our next home project and recommending them to friends and family.
