Worked very closely with Millie and team on a remodel of our 2000 sq feet property in Milpitas and it was a delight to work with Millie and the entire team. Millie took the entire burden off of our shoulders and had her team do some amazing work and a very tight schedule. The work the team has pulled off is amazing and we are extremely happy with the work and looking forward to moving back in.

We recently completed a renovation project with GADI Construction, and I couldn't be happier with the results and service.
From the very beginning, the team truly listened to our vision. They are incredibly flexible and capable of customizing everything to meet specific needs–no matter what idea we threw at them, they always found a practical, creative way to bring it to life. On top of their top-tier craftsmanship, their pricing was very fair and transparent throughout the process.
A special shoutout to our project manager, Nadav, who was exceptional. Nadav's attention to detail is unmatched. He handled all communication with the crew effortlessly and was constantly proactive with quality control, catching and resolving small details before they ever became issues. Because of his dedicated management, I was able to stay focused on my own work and personal life without the typical stress that comes with remodeling.
If you are looking for a reliable, customer-focused contractor that delivers top-quality work at a fair price, I highly recommend GADI Construction and Nadav!
I requested a consolidation to replace our kitchen countertop/ backsplash/ sink. Itay from GADI, did a wonderful job explaining the project process, suggesting different ideas, cost and timeframe.
Thank you Itay!

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..

For homeowners in the Santa Clara and San Jose area, the cost comparison between adding an addition versus building up depends on several factors. Building up, such as adding a second story, often involves higher structural costs, including foundation reinforcement, new roofing, and complex engineering. However, it can be more cost-effective per square foot if you already have a strong foundation and want to preserve yard space. Adding a ground-floor addition typically avoids these structural upgrades but may require expensive foundation work and site preparation. Our internal article titled Build A Garage: What You Need To Know Before You Start provides a detailed breakdown of these considerations. At Gadi Construction, we recommend consulting with a local structural engineer to evaluate your specific property, as soil conditions and zoning in Santa Clara and San Jose can significantly impact costs.
The 30% rule for renovations is a common guideline used in real estate and home improvement. It suggests that the cost of your renovation should not exceed 30% of the property's current market value. For example, if your home is worth $500,000, you should aim to spend no more than $150,000 on a major remodel. This principle helps homeowners avoid over-improving, which can make it difficult to recoup the investment when selling. While this is a useful benchmark, it is not a strict law. For a deeper look into kitchen-specific projects, we recommend reading our internal article titled Remodeling Your Kitchen: What You Need To Know. For homeowners in the Santa Clara CA and San Jose CA area, this rule is particularly relevant given the high property values.
When communicating with your contractor, avoid saying "I can get this material cheaper myself" or "My friend can do this for less," as this undermines trust and suggests you do not value their expertise or negotiated pricing. Also, never say "Just do it quickly" or "I don't care about the details," as this invites shortcuts that compromise quality and safety. For a smooth partnership, focus on clear, respectful communication. For more guidance, refer to our internal article How To Work With Contractors: A Practical Guide For Homeowners, which provides essential advice on setting expectations and avoiding common pitfalls. Gadi Construction emphasizes that honesty and professionalism are key to a successful project.
