Why the Bay Area Chooses Gadi Construction
I engaged GADI Constructions Inc to restore my unit in a high rise in San Jose. Right from the beginning Millie, Project Manager, was very professional and when entrusted with the job completed the repair and restoration work smoothly and in time with perfection with time to time progress reporting on phone and through video.
We explored a home addition for our growing family and these folks handled everything with a lot of thought. The builders explained the remodel plan clearly and made the space blend into the house naturally. It was a solid experience all around.
We recently engaged Gadi Construction for a home renovation project, and the experience exceeded our expectations. Their team demonstrated exceptional flexibility, efficiency, and accommodation, adapting seamlessly to our evolving needs while maintaining a high standard of workmanship. The quality of the final output was impressive, reflecting meticulous attention to detail. Millie, our dedicated project manager, along with her team including Mike, fostered a reassuring and collaborative environment throughout the process, ensuring clear communication and minimal disruption. We highly recommend Gadi Construction for any renovation endeavors; their professionalism and commitment to client satisfaction are commendable.

We worked with Nadav from Gadi Construction during the planning phase of our expansion project, and he was a fantastic advisor throughout the process. He helped us think through every detail — from design implications to quality considerations — and brought a thoughtful, thorough, and methodical approach to each discussion.
Nadav was always friendly, highly professional, and incredibly responsive. It consistently felt like he was acting as a truly independent advisor who cared deeply about building long-term relationships and making sure we would get the very best outcome for our project. His proposals were detailed, insightful, and clearly grounded in deep experience.
Although we ultimately moved forward with another contractor who came through a personal referral, that decision wasn’t a reflection on Nadav’s work or professionalism. Based on our experience, we’d be thrilled to work with him in the future and wholeheartedly recommend him to anyone looking for a trusted, high-quality construction partner.
I went with them for a kitchen makeover and it was worth every penny. The design team helped me see options I never thought about.
Their skilled builders were respectful of the house and kept everything tidy. It felt like a real partnership through the whole remodel.
The value added by the new layout is already noticeable. I still walk in and smile because the remodel turned out exactly right.
Taking on a whole house renovation sounded stressful but they took the edge off. They walked us through each stage of the project so we always knew what was happening. The result feels like a true custom home remodeling job.
The bathroom remodel completely changed how our space feels. Their team helped plan everything so the design made sense and looked great. The quality build is obvious in every corner. It’s nice to have a space that’s functional and adds value at the same time.
We worked with this business for a full residential remodel, and it was a great experience. The skilled builders brought the design to life exactly as we imagined. Every room feels intentional and high-quality. I’d happily recommend them to anyone looking for a thoughtful and professional remodel.

The 30% rule in remodeling is a widely cited budgeting guideline suggesting that homeowners should not spend more than 30% of their home's current market value on a major renovation project. This rule helps prevent over-improvement, where the cost of the remodel exceeds the value it adds to the property, making it difficult to recoup the investment upon sale. For example, on a $500,000 home, the recommended renovation budget would cap at around $150,000. This is a general benchmark; critical factors like the project's scope, local real estate trends, and the homeowner's long-term plans can justify adjustments. It is always prudent to obtain multiple detailed quotes and consult with a real estate professional to ensure financial feasibility and a strong return on investment.
The cost comparison between adding on and building new depends on several factors. Generally, adding an addition can be cheaper than constructing a new, separate building because you are leveraging existing infrastructure like the foundation, utilities, and one or more walls. This reduces material and labor costs for those elements. However, additions often involve complex integration with the existing structure, which can lead to unforeseen expenses like updating old electrical systems or matching roofing materials. Building new typically offers more predictable costs and design freedom but requires a full investment in all site work and construction from the ground up. For an accurate assessment, consult with a professional to evaluate your specific property, local building codes, and project goals.
The cost to design a home addition varies widely based on scope, location, and professional fees. On average, architectural or design fees typically range from 5% to 15% of the total construction cost. For a moderate addition, total construction might cost $50,000 to $200,000, putting design fees roughly between $2,500 and $30,000. Some designers charge a flat fee or an hourly rate of $100 to $250. Key cost factors include the complexity of the design, need for structural engineering, and the number of revisions. It is crucial to invest in professional design to ensure the addition is structurally sound, complies with local building codes, and seamlessly integrates with your existing home. Always obtain detailed quotes from several licensed professionals.
When communicating with your contractor, avoid making statements that can undermine the project's success. Never say, "I don't have a set budget," as this can lead to uncontrolled costs. Avoid, "Just do what you think is best," without clear direction, as it invites scope creep and potential misunderstandings. Do not insist, "My friend said this is how it should be done," as it undermines their expertise and can create conflict. Refrain from asking for major changes after work has begun without discussing impacts on timeline and cost. Also, avoid being overly confrontational about minor issues; instead, address concerns professionally through agreed channels. Clear, respectful communication and a well-defined contract are key to a smooth construction process.
