"I have no skills or vision when it comes to construction, so there was no way I was going to attempt any part or function to finish my basement myself. There is so much involved with finishing a basement that the actual thought of getting it done was exhausting! John and his team made the large task to finish a basement easy! John has the skillsets to do the work and orchestrate different contractors with various skillsets to get each phase of the construction done. Proworks Interiors is very professional and know what they are doing. It was a great relief that they were able to make something that seemed impossible, possible in a matter of a few months."

"Lilco was a great company to work with! They are easy to communicate with and answered all of my questions and concerns. They are reliable and trustworthy. My kitchen and bathroom came out better than I could have imagined. I couldn’t be happier and hope to be able to remodel my other bathroom in the near future."

"Scott rebuilt my kitchen. Not only did he install all of my appliances, he also built me a breakfast nook. Tiles are flushed together making the surfaces smooth and easy to clean. He communicated with me through each process of renovations and addressed all of my concerns. He also built a drainage system through my yard and both at the top and bottom of my driveway to prevent flooding. If I ever had a question, he always had an answer."

Basement Remodel FAQs, answered by experts

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.

If you don’t have a crawl space but have a partial basement you want to make deeper, you can expect to spend a little less—between $40,000 and $90,000 on average. However, if you’re not adding new finished square footage, you won’t see much in the way of ROI.

To determine if your basement walls are suitable for finishing, assess their structural integrity and moisture conditions. Look for any signs of damage, such as cracks, bowing, or excessive moisture. Ensure proper drainage and address any underlying issues before proceeding. 

Consult with a professional if you're uncertain about the structural stability or potential risks associated with finishing your basement walls.

Walkout basements are not generally included in a home’s square footage, although they may be if they meet certain conditions that depend on local regulations. A finished walkout basement used as a living space may be counted toward square footage in some locations as long as all codes for livable space are met.

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.
