Factors influencing garage renovation costs

Tips to save on garage remodel costs

For some aspects of your remodel, it’s best not to cut corners due to safety reasons. (Think: electrical upgrades, plumbing or HVAC installation, or proper demolition.) But there are other areas where you can take steps to lower your overall renovation expenses.

Here are some tips for how to reduce garage remodeling costs: 

• Prioritize needs over wants. Allocate your budget more effectively by identifying your essential needs for the space and prioritize those over less essential features. 
• Choose less expensive materials. Save money by choosing less expensive materials, like low-cost flooring or budget-friendly paint. 
• Remodel during the off-season. Remodel during the off-season (i.e., winter) to save on your project’s total cost of labor. 
• Limit structural changes. If you can work within the confines of your garage’s existing structure and layout, you’ll save more compared to making major structural changes.      

ROI on garage remodels

Your average return on investment (ROI) for remodeling your garage depends on the scope of the project. That said, typically garage remodels have a mid-to-high ROI, ranging from an average return of 64%–81%.
