Why Your Closed Basement Deserves Better
Your basement represents roughly 25-30% of your home’s total square footage, yet most homeowners barely scratch the surface of its potential. This wasted space could dramatically improve your quality of life while boosting property values significantly.
According to the National Association of Realtors, finished basements can increase home values by 10-20%. That’s potentially tens of thousands of dollars in equity sitting beneath your feet, waiting to be activated.
