"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 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 FAQs, answered by experts

Yes, in most cases, finishing a basement is worth the cost. The project adds valuable, usable square footage to your home and typically provides a return on investment (ROI) of 70% to 75%. For example, an average basement refinishing project costing $32,000 could add between $22,400 and $24,000 to your property's value. The final value added depends on factors like your location, the quality of materials and workmanship, and the features you include, such as a living space, bedroom, or bathroom. To be officially counted in your home's total square footage, the finished space must comply with all local building codes, including requirements for points of egress. However, in areas prone to flooding, a finished basement might be seen as a liability by potential buyers and could potentially decrease your home's value.

It is common for a contractor to ask for a down payment before starting a project, especially for jobs that require purchasing materials and equipment or hiring a crew. The deposit amount can range from 10% to 50% of the total job cost. While a request for up to 50% is not unusual, a contractor should not ask for more than that, and you should never pay for a project in full before the work has begun. To protect yourself, always discuss payment terms before starting and have a written contract that outlines the project timeline and expectations. Additionally, be sure to hire reputable contractors and check their licensing and insurance before the project begins.

A finished basement does not always count as square footage, as this varies by state regulations. In areas that allow below-grade spaces to be included in a home's official square footage, the basement must typically meet certain conditions. These conditions often include having a functional egress and being a livable space with flooring, finished walls, and temperature control. To be certain, contact your local assessor to confirm your area's specific policies regarding basement square footage.

Adding a bathroom to your basement can increase your home value since homes with multiple bathrooms sell for more. The return on investment (ROI) for a basement bathroom is 50% to 75%. The actual return varies with your home and location. Adding a half bath to your home increases the value by 2.9% while finishing a basement increases the home value by 6.6%.

Adding an extension or addition to your home costs more than a loft conversion in all but the rarest cases where the home's structural integrity is lacking. Because a home addition requires a new foundation section or significant structural upgrades to handle a cantilevered portion, the cost compared to almost any loft conversion is significantly greater for the same square footage.
