"We recently had our bathroom remodeled by Be Home Remodeling, and I just wanted to share how happy we are with everything. Pouria, our project manager, was great — super organized, always kept us updated, and really listened to any concerns we had. Any time we needed something or had a question, he handled it right away. The crew (Manuel, Isaí )did an awesome job. They worked cleanly, were respectful of our home, and the quality of the work shows. The bathroom turned out even better than we expected, and we honestly love how everything came out. Overall, it was a really smooth experience, and we’d definitely recommend Be Home Remodeling and Pouria if you’re planning a remodel."

"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!"

Basement Remodel FAQs, answered by experts

For most basement remodels, you’ll want to hire a general contractor. This is for a number of reasons, but the main two are that general contractors have dedicated teams they are comfortable with, and hiring one means you only have to deal with one pro. You may also get a better project quote since they can lump all their work and subcontracting into a single quote. 

Common mistakes when finishing basement walls include neglecting proper insulation, insufficient moisture management, and poor ventilation. Not addressing these issues can lead to mold growth, water damage, and discomfort. Additionally, inadequate planning, improper framing, and rushing the project can result in subpar outcomes. 

It's essential to follow best practices, seek professional guidance if needed, and prioritize thoroughness and attention to detail.

The difficulty of adding a basement to an existing house can vary depending on the house’s location, the size of the basement, and the type and condition of the existing foundation. Adding a basement is a job best handled by the pros, so you’ll need to enlist professional help for this project.

Since DIYing a basement remodel isn't typically advised, there are some ways that you can still save money on this project without putting yourself in danger. Some ways to save money on a basement remodel include:

  • Painting walls yourself versus including in the cost of the remodel 

  • Installing light fixtures yourself

  • Choosing prefabricated fixtures, like cabinets, over custom ones

  • Choosing a budget-friendly flooring option, like laminate or vinyl flooring, and add rugs where necessary

Yes, you can add a kitchenette to a basement. However, you’ll have to consider the costs associated with basement kitchenettes. If you’re starting from scratch in an unfinished basement, you’ll need to account for brand-new plumbing, electrical, flooring, and more in addition to the cost of the kitchenette. If you’re putting a kitchenette in an already finished basement equipped with plumbing and electrical, you’ll save considerable money.
