5 Common Renovation Mistakes - And How to Avoid Them

Andra Arnold • November 26, 2025

Renovating your home is an exciting adventure, but let’s be real - it comes with its fair share of headaches. The good news? If your family can survive a home renovation, you can survive anything (seriously, put it on your resume).

Avoiding these common mistakes will help save you time, money, and stress, making the whole process a lot smoother - or at least slightly less chaotic!


Underestimating Costs


Many homeowners misjudge the cost of renovations, leading to budget overruns. Always build a contingency fund of at least 10-15% for unexpected expenses and research realistic pricing for materials and labor before starting your project.


Skipping Permits


It may be tempting to skip permits to save time and money, but doing so can lead to fines, safety issues, or complications when selling your home. Always check local requirements and obtain the necessary permits for your renovations.


Not Hiring Licensed Contractors


Cutting corners by hiring unlicensed or uninsured contractors may save you money upfront but can lead to poor workmanship and costly fixes later. Always verify credentials, ask for references, and ensure your contractor has the proper licenses and insurance.


Focusing on Aesthetics Over Functionality


While it’s fun to choose stylish finishes, don’t lose sight of practicality. Consider how the space will function day-to-day and prioritize upgrades that improve both usability and value, like adding storage or optimizing layouts.


Delaying Selections


Failing to choose materials and finishes in a timely manner can lead to costly delays. Many projects stall because items like tiles, fixtures, or cabinetry are back-ordered. Plan ahead and make selections early to keep your timeline on track.


Renovating can feel overwhelming, but with careful planning and smart decisions, you can avoid these common pitfalls (and safeguard your family’s sanity!). If you’re thinking about renovating to increase your home’s value or preparing to sell, let’s connect! We’d be happy to share more tips to increase your success.
