"We wanted to build on top of an existing garage, but extend out beyond the original building so as to accommodate two large rooms (a bedroom and a playroom), a bathroom and a balcony above and an outdoor dining-room below.. Turn Key Construction did an amazing job as you can see in the photographs. The entire team were courteous and friendly, and patient of the many changes I made as the build was progressing. They made the process enjoyable, and I really don't believe the work they did could be improved upon. We could not be happier with the results."

"Did a wonderful job and takes pride in his work. He was adding a railing to the stairs and replacing stair treads and discovered problems with the raisers. Replaced those as well and provided a competitive price for the amount of work that was completed. We had specific concerns about having this done quickly. Gavin assisted in making sure that he was able to complete the stairs on time despite the additional work. We were happy with the work and outcome."

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.

Renovation enhances functionality, increases home value, and can add new space for personal or family needs. It typically modernizes older unfinished basements for new uses.

Physically, the most challenging part of finishing a basement is installing egress windows or doors when the space is below ground level. Mentally, the hardest part may be envisioning the project and planning around load-bearing and mechanical obstacles.

Joists and beams are both part of the flooring system above your basement, with the beams spanning the length of your home and getting support from vertical posts underneath, and joists usually spanning half the width of your home with no support posts underneath. The floor joists provide even support to the subflooring and flooring above, and they distribute that load to the beams. The beams then distribute that load down through the support posts to the foundation.

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.
