Only Kitchens and Baths Inc
Home Addition & Extension Contractors Near San Ramon
Average rating: 5 out of 5 starsApril 15, 2026
“Did a 2 bathroom remodel with Only Kitchens and Baths and I’m glad we did. We had an older home so there were some surprises behind the walls, but they handled it without making it a huge headache for us. I appreciated that they didn’t try to upsell everything and actually gave practical suggestions. The tile work especially came out really nice. Not the cheapest quote we got, but you can see where the money went!”
EBCON Corporation

“The project that EBCON Co. did for me wrapped up about a week ago. I thought they did an excellent job. The project was to design and build an ensuite addition to my house for my disabled sister, who will be moving in with me in a couple of months. I hired EBCON for the project as they had done my home remodel when I moved into my current house 10 years ago. I was very happy with that project and pleased that several of their key personnel and subcontractors were the same as for my previous project. The current project consisted of a bedroom/studio, bath, hallway/study, walk-through clothes closet, lots of storage space, and small outdoor patio with wheelchair ramp. As my sister is an artist and art teacher, we asked for a design that provided high walls for hanging her paintings and extra space in the bedroom/studio for her to paint and potentially teach a few students. The design process went very well. The designer worked constructively with us and made numerous trips to tile, stone, and carpet stores with us to select materials. We greatly appreciated the detailed plan skeches she generated, some of which showed my sister’s paintings up on the walls in her bedroom/studio! Challenges, including access to the addition through existing bedrooms and integrating the design with the existing house, were solved well. ADA guidelines for accessibility were strictly followed for the design and materials. We – and all our family and friends - love the design and how it has turned out. The construction work was very high quality – EBCON has very high standards for the work done on their projects, including for the smallest details. The EBCON team and the sub-contractors they brought in were great to work with through all the stages, including design, construction, and completion. In addition to weekly on-site progress meetings (which included the project manager, superintendent, designer, and often the head of the company), I was kept informed on a daily basis about what was happening and the timing for next steps. EBCON staff were always on site while work was being done, and they were always reachable for conversations. Overall we are very happy with the project. I would definitely use EBCON again were I to have another project, and I recommend them without reservation to anyone planning a large or small home construction or renovation project.”
CB Architecture + Design
Home Addition & Extension Contractors Near San Ramon
Average rating: 5 out of 5 starsJune 5, 2020
“We used Megan/CB Architecture & Design to help us take our vision to convert our modest, ranch style house into an expanded, open and modern home with tons of natural light. Megan listened to our original ideas and shared many of her own. After much discussion we considered two options before deciding on the direction we wanted to go. Megan understood what our budget was and pointed out if design elements we were pursuing would possibly be over our budgeted amount. Megan's philosophy with her projects is to be present and work closely with the contractor throughout the duration of the project. She essentially acts as a project manager, meeting with the GC and owner on a weekly basis at the job site. She was also available both to the contractor and to me outside of the weekly meetings and would come to the site if the contractor needed her to. Megan had never worked with the contractor i hired but the two worked very well together. I would certainly hire Megan again if we have any future projects and feel fortunate that we found her to design our home.”
