"Ken and his crew built me 2 beautiful bamboo decks. One large and one small. They also replaced all the plywood and siding on the back of my house. Our upper deck, which is the larger one has a water drainage system so we can have a living space underneath. The lower deck, which is the smaller one is flanked by concrete planter boxes and looks awesome! Despite last winters heavy storms, they got the job done quickly and efficiently."

"Our goal was to build a structurally safe garage storage loft. Juan and Julian were a great team to work with. They were very professional and organized- they gave us a quote and clearly communicated what the plan would look like from beginning to end. They guided us on the items that we needed to buy prior to starting the work in order to complete the project within the estimated time. They suggested modifications that were minor fixes but made the layout make more sense in terms of placement. Their crew finished a day ahead of schedule. They kept a clean work site and the quality of the results were great. I would gladly work with them on another home project in the future!"

"Tal was highly recommended by a friend of mine. He came to our house with a portfolio of all the beautiful remodeling jobs he had done. He sent a detailed proposal only a few days later. We had the first floor of our home remodeled which included: kitchen, living room, dining room, family room, and powder room. We had the fireplace totally redone with an electric insert installed. We had luxury vinyl flooring installed ,the popcorn ceiling removed ,recessed lighting, and walls painted. It all looks amazing I feel like I have a new house. Tal was wonderful. He helped us pick out the flooring and the quartz countertops to complement the white shaker cabinets I chose. Everyone that was involved in the remodeling were fantastic. The workers were all very professional and were there every day, except weekends) Tal came every day to check on the progress. He let me know what was going to be done that day and who was coming to do it. Tal always answered my text messages immediately when I had questions too. It took a total of about 7 weeks. They finished on my birthday! When it is time to remodel the 2nd floor we will definitely Choose Bay Builders . (I'm hoping next year) I have recommended them to several friends and neighbors.

FAQs for addition to existing structure building service projects in Scotts Valley, CA
Yes, you can add a bathroom on a concrete slab, but the crew will need to saw-cut the slab, trench in new supply and drain lines, and then patch the concrete without weakening the foundation. Working with an experienced plumber and concrete pro keeps the structure intact and helps the new bathroom pass inspections.
schedule covers planning, permits, framing, rough-ins, finishes, and punch-list items.
Larger spaces or extensive plumbing and electrical upgrades can stretch the timeline, while a simple powder-room conversion may wrap up faster. Hiring licensed pros helps keep the schedule on track and the work up to code.
The best location depends on how your family uses the space. An upstairs bath keeps nighttime trips close to the bedrooms, while a first-floor powder room is handy for guests and everyday traffic.
Think about where plumbing lines already run, how much square footage you can spare, and what layout changes fit your budget. A pro can map out the smartest spot and handle any code hurdles.
With the right planning, you can carve out a bathroom in almost any part of the house. A successful addition requires sufficient space, proper ventilation, and access to plumbing and electrical systems. Structural modifications and adherence to building codes are essential.
This process demands careful planning and the coordination of specialized professionals who ensure that the new space meets all code requirements and functional needs.
Under specific conditions, adding an extra bedroom can boost home value more than adding a bathroom. Home value is driven by overall configuration, market demand, and functional balance. A new bedroom influences the property’s appeal in different ways, while an additional bathroom enhances living convenience. Evaluating the current layout and market trends determines the optimal choice for maximum value.
