"Shay is an outstanding project manager and a creator. He has really looked out for us throughout the re-modal process. His daily communication was essential. I looked forward to the texts, Shay and his team of people kept us informed every step of the remodeling. Shay, built trust with his strong communication and his attention to detail. He made us feel relaxed through the process and I am very happy and excited by the results. Our bathrooms are everything we could have asked for. If we ever do any additional remodeling… we would just call Shay."

"Our experience with Build The Bay on our bathroom remodel project was exceptional from start to finish. The scope of this project consisted of a complete remodel of 2 bathrooms at the same time. Our expectation and the general consensus with any remodel project is that it will be a very stressful experience as the inevitable hidden issues will be discovered leading to additional costs and our project was no exception. The communication with and received from Eitan and the Build The Bay team starting with the bidding process and ending with the final inspection went a long way to reducing our stress level throughout the project. The plan was clearly communicated on a daily basis and every problem encountered came with a proposed solution with an emphasis on minimal cost impact to our budget. The daily planning and communication gave us confidence in their experience and ability to manage the entire project no matter what issue came up. This was evident from the first day taking care to mask walls & floors in order to protect every potential area that could be impacted by construction collateral damage. It was also evident that the work crew had the necessary skills to complete the many varied tasks the project required including framing, sheetrock, electrical, plumbing, tile, floors, windows, texture, paint, as well as the installation of the vanities and all of the additional finishes. The Project Manager Jesus and the entire crew were considerate of our living space and all were professional and friendly throughout the process. Upon completion of the project a deep cleaning was performed and the only evidence that remains of the entire 4 week process are 2 absolutely beautiful bathrooms constructed by Build The Bay!"

"From the beginning, MCA offered excellent help while shopping with us to select materials for each room.  
They allowed space to express our likes and dislikes, while offering experienced suggestions when we were in doubt. 
Prudently, MCA was sure to order and receive all materials before beginning work.
MCA seems quite discerning in selecting their crafts people and associates, like painters, granite finishers, and shower door 
builders.
We found their team of workers to be honest, friendly, highly-skilled, and hard-working.
We learned and respected -- as we had heard widely -- that construction and remodeling has inevitable timing delays and surprise technical puzzles to solve.
Also MCA had days when other jobs and needs delayed our progress.
So at our home, there were days when nothing happened, and balancing moments when one, two, or more craftsmen were on the job. 
Money-wise, the MCA cost estimate was 30% less than the highest competitor.
They were totally true to their financial contract, even when unexpected, added modifications were needed.
Were we to identify MCA's growing edge, it would be improved communication and more focus on continuity to begin and finish in a slightly more timely manner.
We know that is easier for us to ask than it is to fulfill in the challenging world of remodeling and staffing.
It really does take a village to coordinate and complete all of the various requirements -- material choices, teamwork, electrical, plumbing, tiling, and much more.
There are inconveniences, surprises, and a need for patience.
In the end was it all worth it, and would we highly recommend MCA?
We surely would, YES."

FAQs for addition and remodeling projects in Union City, CA

The proper sequence of a kitchen installation starts with laying the foundation and structural framework. From there, you need to establish utilities like plumbing, wiring, and gas lines, then install cabinetry and countertops, and finally finish with flooring, painting, tile backsplashes, and lighting. A professional kitchen installation contractor can coordinate each component of your project to minimize the timeline and maximize resources.
