Home Addition & Extension Contractors Near Castro Valley

“Royalty Builders was consistently professional and on time with our ADU project. Other projects in our neighborhood started at the same and took twice as long. Liroy always quoted us with a reasonable price with any extras we requested. He was knowledgeable of local city codes and worked well with utilities to keep our project moving and get it finished on time. Most importantly we're happy with our beautiful project and would recommend Royalty Builders for your next build.”

“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.”

“We've worked with Ben (Sensitive Information Hidden) before on a complex retaining wall project. Since then, he's launched his own company and we recently completed another piece of work with them. It involved rerouting pipes to the street and as per city permits we needed to cut open a large portion of the sidewalk and pour concrete and asphalt to finish it. BNO builders worked in a timely manner, worked clean and were thoughtful in making decisions on how the pavers would be finished. They were all very pleasant to work with and we are very happy with the results. We highly recommend BNO builders and Ben and his team. Will definitely be using them again.”
