IGreen Builders recently completed our kitchen and primary bathroom renovation in Fremont, and we couldn't be happier with the outcome. From the initial consultation through the final walkthrough, the team remained professional, responsive, and highly organized.The project involved removing a load-bearing wall, updating finishes throughout the kitchen, and creating a beautiful new bathroom space. Every trade performed quality work, and attention to detail was evident in everything from the cabinetry installation to the tile work. Communication remained consistent throughout the project, and the final result exceeded our expectations. Months later, everything continues to perform perfectly.
We hired IGreen Builders for a full kitchen and two-bathroom remodel and overall we are very happy with the experience. From the beginning, the process felt organized and professional. The team helped us understand the sequence of work and what to expect at each stage, which made a stressful renovation much easier to manage. The kitchen came out beautifully especially the layout cabinetry installation countertop finish and overall flow of the space. In the bathrooms, the tile work was one of the highlights of the project. The floor tile and shower tile were installed very cleanly, and the finished look feels polished and high end. We also appreciated the attention given to details like transitions, alignment, grout lines and fixture placement. The crew was respectful hardworking and communicated well throughout the process. We were updated regularly and felt that questions were taken seriously. The new floors throughout the remodeled areas made a huge difference and tied the entire project together nicely. What stood out most was the effort to deliver a clean finished result rather than something rushed. The entire space feels more modern functional and comfortable now. We are glad we moved forward with IGreen Builders and would recommend them to anyone considering a kitchen or bathroom renovation.
