Removing Walls in Older Homes: Special Considerations

Older homes often have unique charm—but they also come with special challenges if you plan to remove a wall. Here’s what you need to know before starting a wall removal project in an older property.

Why Are Older Homes Different?

• Unknown Structure: Blueprints may be missing or inaccurate, making it hard to know which walls are load-bearing.

• Outdated Materials: Walls may contain old electrical wiring, knob-and-tube, asbestos, lead paint, or even hidden pipes.

• Non-standard Framing: Lumber sizes and construction techniques may be very different from modern standards.

• Previous Renovations: Past owners may have done unpermitted work or made structural changes you can’t see.
  

Key Steps for Safe Wall Removal in Older Homes

1. Professional Assessment

A structural engineer can inspect your home and identify all load-bearing walls, outdated materials, and safety risks.

2. Check for Hazardous Materials

Older homes often have asbestos, lead paint, or mold. Specialized testing and safe removal are required before demolition.

3. Update Electrical and Plumbing

Wiring and pipes may need to be replaced or rerouted by licensed professionals.

4. Obtain Permits

You’ll need a building permit, and the city may require extra inspections for safety.

5. Expect Surprises

Budget extra time and money for unexpected issues—older homes nearly always hide a few!

Pro Tips

• Document everything: Take photos before and during the project.

• Communicate with your engineer and contractor: Don’t make assumptions!

• Work with pros experienced in heritage and older homes.
