Why the Bay Area Chooses Gadi Construction
Our home remodeling project is finally complete (almost 2 year ordeal), but team at Gadi Construction made this navigation manageable.
First shout out to Millie Studnict(Project Manager) . If you've ever gone through a major home renovation, you'd have many questions, decisions, surprises, inspections, and frustration. Throughout the entire process, Millie was always there with an answer, a solution, or simply the patience to walk us through the next step.
What I appreciated most was that Millie genuinely cared. No matter how busy things got, she always returned calls, responded to emails, and kept us informed. There were plenty of times when we were unsure about something, and Millie never made us feel like we were asking too many questions.
The entire Gadi team was great to work with as well. The crews showed up when they said they would, treated our home with respect, and were always courteous and professional. It was clear that everyone took pride in their work.
After dealing with the stress of restoring our home following a fire, it was a huge relief to have a contractor we could trust. The project is now complete, the final inspection has passed, and we're very happy with the outcome.
Thank you, Millie and Lucie and everyone at Gadi Construction..

I just wrapped a primary bathroom remodel with GADI.
Effie was a fantastic design partner – he understood our initial vision and worked with it to come up with something even better that we love.
Nadav did an amazing job managing the project. Communication throughout was constant & immediate via text, and we got the project done quickly and with minimal fuss. His team on the ground was also great across the board.
I'm hoping to work with Nadav & Effie on another project soon, and I highly recommend GADI!

I requested a quote for a job I need done and I had the pleasure of meeting Itay today. He was very professional and kind. Had good energy and reassured me that he will do everything he can for the best outcome. This is more of a review on Itay and I will update if I decide to hire them. But the initial process of getting a quote done was great because of Itay.
I recently hadflood damage to my home which requires extensive remodeling. I called a number of contractors And I was most impressed with Millie from Gadi construction.
Though we haven't gotten to the point of actual construction yet , Millie has come out and given me excellent guidance for remodeling bathrooms, kitchen, living area. I've never done remodeling before so it was nice to have somebody like Millie to
' hold my hand,' and take some of the stress off of making some major decisions. She has since returned phone calls promptly and feels more like a friend helping me rather than a person I hired or may hire.
Whether we use you or not in the end thank you Millie for helping me during this difficult time and I hope others see this review and can take advantage of your nice , kind personality and expertise.
Great experience with Gadi on my bathroom remodel. He hired experienced sub-contractors and made sure they showed up on time. Pricing is fair for the work done.
GADI had helped me in demolishing a big mirror wall and remodeling it into a dinning room. I couldn't be happier with the result. Esther and her crew were just amazing and made my dream came true. Great job!

Here are six popular home addition styles among San Francisco residents
This addition opens up your living space with large windows, skylights, and an airy layout. It brings more natural light into your home and creates a warm, inviting area for relaxing, entertaining, or spending time with family.
Perfect for visitors or extended stays, this suite includes a cozy bedroom, a private bath, and a small lounge area. It offers comfort, privacy, and a stylish extension of your existing home, ideal for both family and rental use.
A kitchen extension improves layout, adds storage, and creates a better flow between cooking and dining areas. With more counter space and an open concept design, it turns your kitchen into a bright, functional gathering spot.
A dedicated workspace helps you stay focused, organized, and productive. Designed with natural light, built-in storage, and sound-reducing walls, it’s perfect for remote work or common creative projects for San Francisco professionals.
A second-story addition is ideal for adding significant square footage without sacrificing yard space, a valuable benefit in San Francisco. It can include multiple bedrooms, a new bathroom, or a bonus room, completely transforming your home’s potential.
A sunroom brings outdoor beauty inside with wide windows and relaxing finishes. It’s a cozy space for reading, enjoying views, or unwinding in natural light, offering a peaceful escape within the city.

The cost of a 20x20 addition, which equals 400 square feet, varies significantly based on the scope of work and materials. For a basic, unfinished shell, you might expect costs starting around $30,000 to $50,000. For a fully finished, turn-key addition with standard finishes, the range is typically between $80,000 and $120,000. High-end custom work with premium materials can exceed $150,000. These figures include framing, roofing, siding, windows, electrical, plumbing, and interior finishes. For a precise estimate tailored to your specific needs in Santa Clara and San Jose, a professional contractor like Gadi Construction can provide a detailed breakdown after evaluating your site and design requirements.
The 30% rule for renovations is a general guideline suggesting that you should not spend more than 30% of your home's current market value on a single room renovation, such as a kitchen or bathroom. This helps ensure you do not over-improve your property relative to the neighborhood. For example, if your home is valued at $500,000, you should aim to cap your renovation budget at $150,000 for that room. This rule is not a hard limit, but it helps maintain a good return on investment. For a deeper look into this concept, please read our internal article titled Remodeling Your Kitchen: What You Need To Know.
When communicating with your contractor, avoid saying things that could undermine trust or create confusion. Never tell them "I can get this done cheaper elsewhere," as it signals a lack of confidence in their pricing and expertise. Avoid saying "Just do it quickly," which pressures them to cut corners on safety or quality. Also, do not say "My friend says you should do it this way," as it disrespects their professional judgment. Instead, maintain open and respectful dialogue. For more guidance on building a positive working relationship, refer to our internal article How To Work With Contractors: A Practical Guide For Homeowners. At Gadi Construction, we emphasize clear communication to ensure your project runs smoothly.
For homeowners in Santa Clara and San Jose, the cost difference between adding a first-floor addition versus building up (adding a second story) depends heavily on your existing foundation and structural needs. Generally, building up is more expensive per square foot because it requires reinforcing the existing foundation, adding structural steel, and dealing with complex roofing and waterproofing. However, a first-floor addition may require expensive foundation work and can reduce your yard space. To make an informed decision, we strongly recommend reading our internal article titled Build A Garage: What You Need To Know Before You Start. This resource provides a detailed cost breakdown and key considerations for your specific property. At Gadi Construction, we always advise clients to get a professional structural evaluation before choosing either option.
