DIY vs. Hire a Professional — How to Decide

The Real Cost of DIY

DIY can save money — but only when it’s the right project, done correctly. Hidden costs include your time, tool rental or purchase, mistakes requiring professional correction, and permit costs.

Projects DIY-Friendly for Most Homeowners

• Painting (interior and exterior)
• Minor deck repairs and staining
• Basic landscaping and grading
• Tile work (with proper prep)
• Cabinet hardware and fixture replacement

Projects That Typically Require a Pro

• Electrical panel work — code compliance, permit required, safety risk
• Main water line or gas line work
• Structural changes (load-bearing walls, foundation)
• Roofing (risk of injury, improper installation voids manufacturer warranty)
• HVAC installation (requires EPA 608 certification)

The Permit Question

Many homeowners skip permits to save money. This creates a serious problem at resale — unpermitted work must be disclosed and can kill deals. The fine for unpermitted work often costs more than the permit would have.
