How much does electrical re-wiring cost in Baltimore?

If you own an older home in Baltimore, the chances are the electrical wiring might not meet modern safety standards—or your power needs. Whether you’re renovating, experiencing flickering lights, or dealing with tripped breakers, electrical rewiring may be necessary. But how much will it cost?

Here’s a breakdown of what homeowners in Baltimore, MD, can expect when budgeting for a full or partial home rewire.

What Is Electrical Rewiring?

Rewiring involves replacing outdated, damaged, or insufficient electrical wiring in a home. This often includes:

• Upgrading wiring to meet current codes
• Installing new outlets and switches
• Replacing the electrical panel (if needed)
• Adding grounding and GFCI/AFCI protection
• Sometimes opening up walls to access wiring

Here’s what influences the cost:

These are ballpark estimates based on local Baltimore pricing as of 2025. Actual costs can vary.

Factors That Affect the Cost

1. Age of the Home

Older homes with outdated systems (e.g. knob-and-tube or aluminum wiring) are harder to rewire and may require wall repairs, increasing labor costs.

2. Access to Wiring

If your electrician can access wiring through basements, crawl spaces, or attics, the job is easier—and cheaper. If walls need to be opened and patched, costs go up.

3. Electrical Panel Upgrade

If your home’s electrical panel is outdated (e.g. under 100 amps), you may need to upgrade it, which can cost $1,500–$3,000 extra.

4. Permit & Inspection Fees

In Baltimore, permits for electrical work are required and cost $100–$300, depending on the scope of work. Inspections are usually included in your electrician’s estimate.

5. Labor Costs

Licensed electricians in Baltimore typically charge between $75 and $125 per hour. Bigger jobs may involve a team, increasing overall labor costs.

Partial vs. Full Rewiring

You may not need a full rewire. Here are the typical costs for common partial upgrades:

• Rewiring a kitchen or bathroom: $1,000 – $3,000
• Installing new circuits or outlets: $150 – $500 per unit
• Replacing old two-prong outlets with grounded outlets: $100 – $200 each
• Upgrading from 100 to 200 amp service: $2,000 – $3,500

Is Rewiring Worth the Cost?

Yes—especially if:

• Your home was built before 1970 and hasn’t been updated
• You notice flickering lights or frequently blown fuses
• You’re renovating or adding major appliances
• You want to increase your home’s resale value

Electrical rewiring makes your home safer, more energy-efficient, and compliant with modern building codes.

Tips to Save Money on Rewiring in Baltimore

• Get multiple quotes from licensed electricians.
• Ask about “fishing” wires to avoid wall damage.
• Combine rewiring with renovations to minimize labor costs.
• Check for rebates or financing through BGE (Baltimore Gas and Electric) or city programs.

Important: Always Hire a Licensed Electrician

Rewiring is not a DIY job. It’s critical for your safety (and your homeowner’s insurance) to use a licensed electrician familiar with Maryland and Baltimore City code requirements.

Final Thoughts

While rewiring a home in Baltimore can cost several thousand dollars, it’s a smart investment in safety and peace of mind. Knowing the average cost and what factors affect pricing can help you plan and budget smarter.
