E & J Builders was founded by husband and wife team Eric & Jane Sterken. E & J Builders is dedicated to providing quality craftsmanship, clear communication, fair prices, and a really positive attitude! We know there are many things to consider when choosing a contractor: capabilities, schedule, cost and good communication. It’s important to choose someone you feel comfortable working with and having in your home.
"We did a massive home remodel with Eric and his team at E&J, and they were phenomenal. The scope of the project was bigger than we expected, and we were in over our heads, and Eric helped at each step of the way. He worked closely with our architect and the city inspectors to finish up our beautiful home. I've recommended him to a number of friends. Their bid was well below the others we got, and they really delivered. It was to the studs/new foundation in almost half the house, the scope was across new bathrooms, kitchen, bedrooms, windows, floors, electrical plumbing, attic, roof deck and more. He managed all the complexity and subcontractors. Not only has he stood by all the work to make sure all the details were right, but he's just a genuinely nice and wonderful person who is a pleasure to work with. Highly recommend him and his team."

FAQs for addition to existing structure building service projects in El Cerrito, 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.
