"My wife and I needed to finish our basement to accommodate our growing kids. We had an excellent experience with Everything Under The Roof. They really listened to what we wanted to build and everything was done well, on-time, and on-budget. One thing I particularly appreciated is that the owner was onsite doing the work, and not simply sending a team of workers. We'll definitely be using Everything Under The Roof for any future projects."

"The work was done in a timely manner, and as I was told we needed to wait to paint the stairs, and that was the last item, i paid in full. It has now been over a year and i keep requesting that they come out and complete the work, and i receive no response. Disappointed."

Basement Remodel FAQs, answered by experts

It is generally more affordable to finish a basement than an attic, though it ultimately depends on how you plan to use the space. The average cost to finish a basement ranges from $7 to $23 per square foot, while attic renovation costs $30 to $60 per square foot. However, a simple attic conversion to a storage space will cost significantly less.

Save money on your basement finishing project by making cost-effective decisions such as minimizing structural changes and avoiding costly construction revisions. DIY simpler tasks such as painting or basic cleanup to reduce labor costs. You can also opt for energy-efficient fixtures and materials that may qualify for rebates or tax incentives.

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.

Professional remodelers streamline the process, manage permits, and handle renovations efficiently—significantly mitigating risk while maintaining standards.

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.
