"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!"

"My project was a major renovation of a 1985 Victorian home that suffered a devastating fire. Erik and his team did a beautiful job following my architect’s plans, and was also proactive about calling out necessary changes. He was very patient with all of my changes and very specific requests, and was a very calming influence when unexpected surprises inevitably arose during construction. The final results are beautiful, and an historic house has been saved. I look forward to working with Erik again in the future!"

Basement Remodel FAQs, answered by experts

It is generally more affordable to finish a basement than an attic, though it ultimately depends on how you plan to use the space. The average cost to finish a basement ranges from $7 to $23 per square foot, while attic renovation costs $30 to $60 per square foot. However, a simple attic conversion to a storage space will cost significantly less.

When choosing materials for finishing basement walls, consider factors such as moisture resistance, durability, and fire resistance. Opt for materials specifically designed for basement environments, like moisture-resistant drywall or cement board. Insulation with vapor barriers can help regulate temperature and prevent condensation. Consider using mold-resistant paints or coatings. 

Research and consult with experts to select materials that are suitable for your specific basement conditions and intended use. Prioritize quality and compatibility to achieve long-lasting and aesthetically pleasing results.

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.

The average cost to remodel a basement is between $12,100 and $33,400. Depending on the project's complexity, the price can be as low as $3,500 or exceed $50,200. For a simple project like adding a home office, you might spend between $500 and $3,000. However, a more extensive project, such as adding a bathroom, can range from $6,600 to $16,500. The final cost is influenced by factors like the basement's size and condition, the type of remodel, material choices, your location, and accessibility. For an accurate price, it's best to consult with a basement remodeling team.

When considering finishing your basement, take into account a few pros and cons:

Pros

  • Can increase the value of your home

  • Separate space from the rest of the house 

  • Customize and personalize the basement to suit your needs and style

  • Increase the amount of living space in your home

Cons

  • May not regain enough value to cover the cost of finishing

  • Lack of natural light if it’s below ground level

  • Moisture or flooding can cause costly damage

  • Installing plumbing and electrical can be messy and costly
