"We hire Geico builders for our kitchen remodeling project, and I'm happy to share my experience: Working with Zaya and Geico Builders was a great decision. They were professional, friendly, and easy to work with. From 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 to 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 found Cal Green Remodeling while searching for companies on google. After meeting a few companies, we decided Shay was the best choice for us. The main reason we went with Shay and Cal Green, was because of his honest appraoch to the the whole process. While it appeared the others were saying what we wanted to hear, Shay told us the facts without attempting to lighten the situstion. For example the timeline with Shay seemed realistc compared to the others and also he provided a very detailed estimate that covered all cost and potential cost involved. Simply stated Shay made us feel comfortable. As we expected, he was the best choice. The process was smooth and Shay kept us in constant communication with updates, and completed the work on schedule. Our kitchen came out amazing and we love it! I would highly recomend Shay and Cal Green Remodeling for your home renovation. Thanks again to Shay and Cal Green Remodeling!"

Basement Remodel questions, answered by experts

A walkout basement is considered to be partially below grade because at least one wall is entirely exposed. In some cases and in specific municipalities, inspectors and appraisers will still count walkout basements as below grade, which means the space can’t serve as living space or be rented out. If you intend on using the area as living space or a separate apartment, you should check with your local building department to make sure it’s legal to do so.

Installing a bathroom in a basement isn’t a project for most homeowners. Many parts—plumbing, electricity, and carpentry—go into this project, each requiring expert-level knowledge and tools. One miscalculation can lead to very expensive repairs. Plus, some homeowner’s insurance might not pay for damages caused by a homeowner DIYing this project. You can protect yourself by allowing the pros to complete this job for you. 

Yes, most general contractors require an initial down payment. A reasonable deposit is typically between 10% and 25% of the total project cost, although this can vary by project size and location. This upfront payment helps the contractor cover initial costs like materials, permits, licensing, and hiring subcontractors. The remaining balance is usually billed according to a schedule outlined in your contract, often tied to project milestones or completion dates. Be cautious of contractors who ask for a large deposit of 50% or more, as this could be a red flag for a scam.

Living in a finished basement is acceptable, but only if the space has the proper points of egress and includes smoke and carbon monoxide (CO) detectors to ensure the safety of the occupants. A good way to ensure your finished basement is suitable for use as living space is to get the basement finishing project properly permitted.

You should plan on waiting at least a year and ideally two to three years after construction before finishing your basement. This will give the foundation time to settle in response to the weight of your home and the expansion of the surrounding soil. You can then repair your foundation and seal any cracks as needed before finishing it to reduce your risk of future leaks or other issues.
