DIY Home Repair: What You Can Do Yourself (and What You Shouldn't)

DIY-Friendly Projects (with moderate skill)

• Painting (interior and exterior): Largest DIY money-saver. Saves $2,000–8,000 on a full home interior. Requires patience and proper prep — but no special licensing or tools.
• Tile installation: Learning curve is real but manageable. Backsplashes are easier than floors; shower tile is harder. Wrong substrate (lacking Schluter or Kerdi membrane in wet areas) leads to failure within years.
• Drywall patching: Small holes and seams are learnable. Large drywall repairs require more skill to blend invisibly.
• Deck building: Intermediate DIY. Requires proper ledger attachment and footing depth — get a permit and inspection.
• Landscaping: Mulching, planting, edging, small grading — straightforward DIY.
• Basic plumbing: Replacing fixtures, faucets, toilet fill valves. Anything with shutoff valves readily accessible.
• Flooring installation: LVP click-lock flooring is the most DIY-friendly. Hardwood nail-down is harder.

Hire a Professional

• Electrical panel work: Dangerous without training. Permits required. Licensed electrician only.
• Structural modifications: Load-bearing wall removal, foundation work, adding rooms — require engineering and inspections.
• Roof replacement: Falls are the leading construction injury. Professional roofing with proper insurance coverage is standard.
• Gas line work: Extremely dangerous. Licensed plumber or gas fitter only.
• HVAC refrigerant work: Requires EPA Section 608 certification to handle refrigerants legally.
