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!

Create an inviting space where everyone can relax, gather, and enjoy natural light. With big windows, open layouts, and comfortable finishes, it becomes the true heart of your home. This addition instantly makes your home feel larger, brighter, and more welcoming.
Add a self-contained suite complete with a bedroom, bathroom, and living area. It’s ideal for long-term guests, extended family, or extra rental income. This suite offers independence and privacy while still being connected to your home.
Perfect for remote workers, artists, or students, this space boosts focus and organization. With custom storage and proper lighting, it becomes a productive zone tailored to your work. It gives you a quiet environment to think, create, and stay inspired.
Add a complete second floor to significantly increase your living space without altering your lot. Include bedrooms, bathrooms, or a multi-use loft. This upgrade is one of the most impactful ways to expand both space and property value.
A small expansion can dramatically improve your kitchen’s flow, storage, and openness. More room for cooking, gathering, and enjoying meals. This addition helps transform your kitchen into a brighter and more functional culinary space.

The cost of a 20x20 addition, which totals 400 square feet, varies significantly based on complexity, materials, and local labor rates. In the Santa Clara CA and San Jose CA area, you can generally expect a price range between $250 and $400 per square foot. This means a total project cost could fall between $100,000 and $160,000. This estimate typically covers foundation, framing, roofing, basic electrical and plumbing, insulation, drywall, and standard finishes. However, factors like high-end cabinetry, custom windows, or structural changes will increase the budget. For a detailed breakdown of a similar project, we recommend reviewing our internal article titled Monte Sereno Case Study: Second-Story Addition. Always obtain multiple bids from licensed contractors to ensure your specific scope and site conditions are accurately priced.
The 30% rule in remodeling is a general guideline suggesting that the cost of a kitchen or bathroom renovation should not exceed 30% of your home's total value. This principle helps homeowners avoid over-improving a property relative to its neighborhood, ensuring a better return on investment. For example, if your home is valued at $500,000, your kitchen remodel budget should ideally stay around $150,000. While this is a useful benchmark, it is not a strict rule. Factors like local market conditions and your personal goals also matter. For more detailed guidance, please refer to our internal article titled Remodeling Your Kitchen: What You Need To Know. At Gadi Construction, we always recommend balancing your vision with smart financial planning for your Santa Clara or San Jose home.
When deciding whether to add an addition or build up, building up is often the more cost-effective option. Adding a second story typically requires less foundation and roofing work, which can reduce material and labor expenses. However, this choice depends on your existing structure's load-bearing capacity and local zoning laws. An addition expands your home's footprint, which may require more extensive site preparation and permits. For homeowners in Santa Clara CA and San Jose, CA area, evaluating these factors is crucial. For professional guidance, refer to our internal article Build A Garage: What You Need To Know Before You Start for detailed insights. Gadi Construction recommends consulting a structural engineer to assess your property before making a decision.
For a 1,000 square foot addition in the Santa Clara and San Jose area, costs typically range from $250 to $400 per square foot, placing the total between $250,000 and $400,000. This wide range depends on factors like foundation work, roof complexity, and interior finishes. High-end materials or structural changes can push costs higher, while simpler designs may fall on the lower end. Permits and engineering fees in this region add significant expense. For a more cost-effective approach, consider an Accessory Dwelling Unit (ADU) instead of a traditional addition. To explore this option, review our internal article titled 'Prefab Vs. Custom ADUs: Santa Clara Cost Analysis' at Prefab Vs. Custom ADUs: Santa Clara Cost Analysis. Gadi Construction recommends obtaining multiple detailed bids to compare structural and finish costs before proceeding.
