"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 questions, answered by experts

While bathrooms and kitchens are nearly equal in terms of renovation difficulty, kitchens are the most challenging. Kitchen design, layout, electrical, and plumbing needs all depend on each other for the success of the entire project, and mistakes early in the project can cause trouble later on.

Framing a basement takes three to five days, on average, when completed by a professional, though it may take longer for a larger space. Keep in mind this doesn’t include the time to complete the design, obtain permits, and install the drywall on the framing. On average, fully finishing a basement takes an average of 45 days.

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.

It’s less expensive to finish your basement than it is to build an addition to your home. The average cost to refinish a basement is $32,000 (between $7 and $23 per square foot) while building an addition to your home costs $50,325 ($80 to $210 per square foot). Depending on the size of your basement and other factors, like moving plumbing and electrical, refinishing a basement is a more cost-effective option in most cases.

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.
