"My journey began when I met Mario from Be Home Remodeling. 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"

They were professional, friendly, and easy to work with. From 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 to 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.

"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

Living in a finished basement is acceptable, but only if the space has the proper points of egress and includes smoke and carbon monoxide (CO) detectors to ensure the safety of the occupants. A good way to ensure your finished basement is suitable for use as living space is to get the basement finishing project properly permitted.

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

Permits may be required for major repairs, structural work, or electrical and plumbing restoration after a flood. Check with your local building department to determine permit requirements and associated fees for your flooded basement cleanup project. Obtaining the correct permits helps ensure work is done safely and up to code.

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.

Some older homes have toilets in the basement to combat sewage backups. This type of toilet, also known as a Pittsburgh potty, acted as a safety valve over the incoming sewer line. If a line backed up, it would back up into the toilet because it was the lowest fixture in the home, keeping it out of sight and away from the finished areas of the house.

Basement toilets were also used by workers with messy jobs, like those who worked in coal mines or steel mills. This way, they could clean up and avoid tracking dirt through their home.
