🚧 DIY Projects That Can Ruin Your Home Inspection

Not all do-it-yourself projects save money. Some can hurt your home’s value or even cause a buyer to walk away. Here are common DIY mistakes that show up on inspection reports—and how to avoid them.


1. 🧰 Unpermitted Electrical Work

Red Flags for Inspectors:

  • Open junction boxes

  • Double-tapped breakers

  • Wiring not to code or improperly grounded

Why It’s a Problem:
Unsafe wiring can cause shocks, fires, or insurance issues. Inspectors will flag it, and buyers may demand repairs by a licensed electrician.

What to Do Instead:
Always pull permits and hire an electrician for panel upgrades or major wiring jobs.


2. 🚽 Poorly Done Plumbing Repairs

Examples:

  • DIY-installed water lines or PEX with questionable fittings

  • Improper slope on drains

  • Leaky shutoff valves or traps

Why It’s a Problem:
Water damage is a huge concern for buyers and lenders. A leak under a sink or in a crawl space can raise serious red flags.

Tip:
If you're not 100% confident, bring in a licensed plumber, especially for anything behind walls or under floors.


3. 🏠 Structural Changes Without a Permit

Examples:

  • Removing a wall (possibly load-bearing)

  • Adding a room or deck without plans or inspections

Why It’s a Problem:
These changes may compromise the integrity of your home or violate local building codes.

What to Do:
Always get a structural engineer’s input before removing walls, and pull proper permits.


4. 🔌 Improvised HVAC Fixes

Examples:

  • Ductwork patched with tape

  • Unauthorized mini-split installs

  • Blocking returns or vents

Why It’s a Problem:
These fixes can reduce efficiency, cause condensation or mold, and lead to system failure.

What to Do:
Leave HVAC upgrades to certified pros and maintain proper airflow design.


5. 🪟 Sloppy Window or Door Installs

Issues:

  • Gaps and poor insulation

  • Water intrusion

  • Sticking doors due to improper framing

Why It’s a Problem:
Poor installs affect energy efficiency, moisture control, and overall quality perception.

What to Do:
Measure twice, follow manufacturer instructions, and seal properly—or hire it out.


🚫 Bottom Line:

DIY can be satisfying, but cutting corners shows up during inspection. If it's structural, electrical, plumbing, or HVAC-related, it's usually best left to a pro.
