I started with just one bathroom remodel, and I was immediately impressed by the professionalism, attention to detail, and high-quality craftsmanship he and his team delivered. The communication throughout the project was clear and consistent, and they made sure every step met my expectations. Since then, I?ve trusted Be Home Remodeling with additional projects and have always been more than satisfied with the results. Highly recommend Mario and his team to anyone looking for reliable and high-quality construction work"

"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!"

"We finally have a bathroom that feels like a luxury hotel. The walk-in shower, custom vanity, tile work, and lighting all came together perfectly. Every detail was done with precision, and the quality is obvious the moment you walk in. The crew was always on time, kept the work area clean, and made the entire remodeling process much less stressful than we expected. We couldn’t be happier with the transformation and would absolutely choose Builders Group again for our next project"

Basement Remodel FAQs, answered by experts

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.

Although homeowners often use the terms basement remodeling and basement finishing interchangeably, they are quite different terms. 

Finishing a basement is the process of taking a basement space that is not habitable and adding elements to make it usable. This includes adding plumbing, flooring, and insulation.

Remodeling a basement means taking an already existing finished basement and changing it, often by adding or removing walls, adding plumbing, or changing the existing flooring.

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.

The average cost of remodeling a basement is $30 to $75 per square foot. If your space is unfinished and looks like it may need more help, use the higher number when calculating your estimated basement remodeling costs. A good rule of thumb is to add an additional 20% to the top of your estimate to cover any “what if” situations.

Efficient appliance positioning, optimizing existing plumbing, and sourcing energy-efficient materials reduce financial impact and increase sustainability.
