Many home projects involve real hazards
Renovation and repair work can cause serious injury, property damage, fire, electrocution, poisoning, or death if done improperly. Hazards include, but are not limited to:
- Structural work — removing or altering load-bearing walls, framing, beams, or foundations can cause collapse.
- Electrical work — risk of electrocution, shock, and fire.
- Gas work — risk of leaks, explosion, and carbon monoxide poisoning.
- Plumbing work — risk of water damage, contamination, and scalding.
- Asbestos, lead paint, and mold — serious health hazards that require specialized, regulated handling and testing.
- Roof and height work — risk of falls and serious injury.
We do not provide hazardous how-to instructions
Our content focuses on cost and planning, not step-by-step instructions for dangerous work. We intentionally do not provide procedures for tasks such as electrical wiring, gas fitting, structural modification, or asbestos, lead, and mold remediation. For that work, hire a qualified, licensed professional.
Codes, permits, and licensing vary
Building codes, permit requirements, and licensing rules differ by state, county, and city, and they change over time. A project that is permitted one way in one jurisdiction may be prohibited or require inspection in another. Our estimates cannot account for your local requirements. Always check with your local building department before beginning work.
Do not rely on this Site for safety-critical decisions
Nothing on this Site should be treated as a substitute for professional judgment, inspection, or licensed work. If a project could affect the structural integrity of your home, your electrical or gas systems, or your health, consult a licensed local professional before proceeding.
