"We hire Geico Builders for our kitchen remodeling project, and I'm happy to share my experience: working with Zaya and Geico Builders team was a great decision. They were professional, friendly, and easy to work with. Form the start, the process was smooth and efficient. The craftmanship of my remodel kitchen and attention to detail were exceptional, and the end result far exceeded my expectations. From the design phase top completion, their communication was excellent, and I felt completely at ease with them working in my home. The design solutions completely transformed my kitchen, making it both functional and beautiful. I highly recommend Geico Builders for anyone looking for a stress-free and satisfying remodeling experience."

"We were looking to remodel our kitchen or bath for a few years. We kept getting estimates from different companies and always felt the price was off or the person was not a good fit. Then, finally, we met Shai with Cal Green Remodeling. What a great guy! He is very upfront and honest about what we can expect in terms of cost and work flow. Because of his honest approach, we hired him. We felt he gave us the good and bad and how to resolve the bad as well. In the end, the process was fairly smooth, and the few hick-ups we had, for example, the city and their permit process, were well explained to us at the beginning, so we were ready. Our kitchen or bath looks amazing, and I plan to work with Cal Green Remodeling again. Thanks Shai!"

"We needed an additional office space within our home. The concerns were removing an existing fireplace and hearth and replacing the hardwood floor to match what was already there, removing the chimney and patching the roof, moving a heating vent and again, patching the hardwood floors to match, adding an interior door, and moving lighting and electrical outlets. David was onsite everyday to either do the work himself or oversee the work by his subcontractors. They do quality work. The floors look great, the new wall is perfect, the roof was done well, the new interior door was installed well and looks like it was always meant to be there. Also, the work site was always cleaned up at the end of each work day. David is also very flexible, easy to communicate with, seems to truly care about your project, and works with contractors who do quality work."

Basement Remodel FAQs, answered by experts

If you have the woodworking experience to build a bar from scratch and you have the time, DIYing the work is a no-brainer and can save a few thousand dollars. However, if you’re looking to include a sink, additional lighting fixtures, or high-end bar tops and cabinets, it’s usually a better idea to call in a pro. It will cost more, but the finished product will likely be worth it.

Create a checklist, reimagine the space use, set a realistic budget, choose materials and aesthetic details, and get professional support for guidelines and troubleshooting.

You can paint your ceiling or install a drywall ceiling if the ceiling is unfinished, as they take up less headroom than drop ceilings. 

If there are pipes in the way of ceiling installation, you can do one of two things: reroute the pipes or adjust the installation to fit, which will cost extra.

Lifting a house and adding a basement is one way to add usable square footage. Lifting or jacking a house is a complex process, and it can be expensive, not to mention that you won’t be able to live in your house while it’s lifted, due to safety concerns. Lifting a house should only be done by experienced professionals.

Renovation enhances functionality, increases home value, and can add new space for personal or family needs. It typically modernizes older unfinished basements for new uses.
