Geico Builders specializes in meeting your expectations before, during, and after the project is complete. Our most upstanding quality is our accountability--you can expect us to own the work we complete for your home. Of course, we know accountability means nothing without proof, which is why we are happy to offer a 2-year workmanship warranty to all of our clients. This is a rare quality for this industry, but we wanted to prove to you that we stand by our craftsmanship through our home remodeling construction services. Every Crew at Geico Builders has been professionally trained and will treat your home with integrity and respect.

"We used Geico Builders for our bathroom remodel. We collected a few quotes, and we felt like the quote for the value was the best. I appreciated the clear scope and payment schedule. We started with a tiny bathroom and had plans to remove a couple of walls to make it larger. Leading up to demo day, our project manager Mila and the team pulled permits and helped us understand which finishes/materials we needed to order. I had a clear idea of our design vision, so I didn't need a lot of assistance there, but I found the 3D rendering helpful to see. Our project took a little over 5 weeks. The foreman David and crew did a great job. I was many specific requests, and I felt like David always did his best to incorporate my requests. We had a few hiccups, as with any project. We ran out of tile, which caused a small delay. The crew also misplaced some of our shower fixtures and we had to reorder them. The team was able to cover the cost of these, which I appreciated. I liked how we had a group to stay on top of updates. There were times when I would have liked more communication regarding the crew's schedule, delays, etc. but overall, I felt like my questions were always answered. Love my new bathroom, thank you."

FAQs for basement remodeling projects in Concord, CA

While the terms remodeling, renovating, and finishing are often used interchangeably, there are some differences. Remodeling your basement transforms the space by changing its layout, adding new features, or altering its function. Renovating restores the existing space to like-new condition without major structural changes. Finishing converts an unfinished basement into a livable area with walls, ceilings, and flooring.

A full basement remodel typically takes two to six weeks, depending on the project's complexity and any unforeseen challenges. Factors like design changes, permitting, and material availability can affect the timeline, as well as the availability of the contractors you’re working with. Remember that the bigger the project, the longer it will take to complete.

Remodeling your basement is not just about gaining extra space—it's a savvy investment. You can expect around a 70% return on investment (ROI), comparable to other major home improvements like kitchen or bathroom remodels. Adding functional living space boosts your home's value and appeals to potential buyers. Plus, converting your basement into a rental apartment could provide additional income, increasing your return even more.
