Rewiring a House Cost Estimates: Key Insights for Professionals

Rewiring a house in the Boston area can significantly enhance safety and functionality. However, estimating costs accurately is crucial for contractors. Current rewiring costs range from $8,500 to $35,000 depending on the size and complexity of the project. This guide provides insights into the main cost drivers and how to leverage technology for precise estimates.

Key Factors Influencing Rewiring Costs

1. Square Footage and Layout Complexity

Smaller homes may require around 600 feet of wiring, while larger homes can exceed 2,500 feet. Open layouts reduce labor costs, whereas finished ceilings increase them.

2. Service Upgrade Requirements

Upgrading from a 60-amp to a 200-amp service can add $2,500-$4,000. Ensure estimates include inspection and utility coordination fees.

3. Fixture and Device Count

Adding LED lights and smart devices increases both material and labor costs. Accurate tagging during site walks ensures nothing is missed.

4. Wall Surface Restoration

Restoring plaster in historic homes can double costs compared to drywall. Use current local rates for accurate estimates.

Average Cost Ranges in Greater Boston

Boston labor costs are 10-15% higher than the national average. Typical costs include:

  • 1,000 sq ft condo: $8,500 – $11,000
  • 2,000 sq ft single-family: $15,000 – $21,000
  • 3,000 sq ft historic home: $24,000 – $35,000

These estimates cover permits, panels, and basic fixtures. Adjust for high-end options as needed.
