Enhancing Energy Efficiency Through Home Rewiring Techniques – San Francisco Bay Area Electrician

Are you looking to enhance the energy efficiency of your San Francisco Bay Area home? Upgrading your home’s electrical wiring can greatly improve energy efficiency and safety. Read on to learn how partnering with a Bay Area electrician for a rewiring project can benefit your home.

Installing new, updated electrical wiring optimizes energy use and prepares homes for modern appliances and electronics. With rewiring, older homes built before 200 amp service became standard can upgrade to meet today’s energy demands. Rewiring ensures sufficient power for multiple devices, EV chargers, and air conditioners without overload.

This article explores reasons for rewiring older homes, wiring project costs, finding reputable electrical contractor, safety considerations, and rewiring procedures. Let’s electrify your home’s energy efficiency through smart rewiring upgrades. Have a new construction project you need rewired? We can help with that too!

Why Rewire an Older Home?

Many San Francisco Bay Area homes, especially those built before the 1960s, likely contain outdated 60 amp electrical systems. While adequate decades ago, 60 amp service strains to support increased energy usage in modern times.

Here are key reasons you may benefit from rewiring your older Bay Area home:

  • Insufficient amperage – Today’s homes need 100, 150 or 200 amp service. Upgrading provides capacity for more high-wattage appliances and electronics without blowing fuses.

  • Faulty, damaged wiring – Outdated wiring becomes cracked and hazardous over time. Rewiring prevents short circuits and fires.

  • Lack of grounding – Modern 3-prong grounded outlets prevent shocks. Rewiring brings grounding up to code.

  • Circuit overload – More built-in appliances and electronics require adequate circuits. Additional circuits prevent overloads.

  • Lighting needs – Rewiring allows more switches, outlets, and lighting options. New wiring supports elegant lighting designs.

  • Smart home integration – Modern automated, app-controlled smart home systems often require rewiring for full functionality.

  • Accommodate home additions – If you’ve added a room, garage, pool house or other living space, rewiring may be needed to provide power.

  • Charge EVs – Today’s electric vehicles require dedicated high-capacity circuits and 240-volt outlets that may necessitate rewiring.

Key Takeaway: Rewiring optimizes electrical systems for ample power, capacity, safety, and integration with modern devices and home automation.

Estimated Costs of Home Rewiring Projects

Full home rewiring costs vary widely based on factors like:

  • Home’s square footage
  • Number of circuits required
  • Type and scope of work needed
  • Bay Area electrician rates

Budget Electrical only expects full home rewiring to cost $8,000 to $15,000 on average. However, smaller homes or those needing simpler updates may only cost $3,000 to $7,000. Larger homes requiring extensive work could exceed $15,000.

Here are examples of rewiring project costs:

  • 1,200 sq ft home needing new 100 amp service with 8 circuits – $3,500
  • 2,800 sq ft home needing new 200 amp service with 15 circuits – $9,800
  • 4,000 sq ft home with new 400 amp service, 20 circuits, hot tub hookup – $13,500
  • 5,000 sq ft home requiring complete rewire of damaged old wiring – $18,000+

Get quotes from multiple licensed Bay Area electrician before moving forward with a big rewiring project. Ask about their rates, the specific tasks included, types of wiring used, and estimated completion time.

Consider upgrading wiring in phases if costs seem prohibitive. For example, start by rewiring the kitchen or rooms that need it most urgently.

  • Turn off power at the main circuit breaker before starting work.

  • Test wires are de-energized with a non-contact voltage tester.

  • Keep children and pets away from the work area for safety.

  • Never leave exposed live wires unattended. Cap wires until connections are made.

  • Allow only a licensed Bay Area electrician to handle the electrical panel and make new connections.

  • If caught in a storm, stop work until it passes to avoid lightning risks.

  • Keep the work area dry. Never work in standing water to avoid electrocution.

  • Ensure wiring complies with national and local electrical codes.

  • Have the completed work inspected before turning power back on.

  • Keep a fire extinguisher and first aid kit handy in case of emergencies.

  • Wear rubber-soled shoes and eye protection when working with wiring.

Step-By-Step Rewiring Process

How do electricians actually rewire an older home from start to finish? Here’s an overview of the typical rewiring process:

1. Full Inspection

The Bay Area electrician will assess:

  • Amperage of existing wires

  • Number and type of circuits

  • Grounded vs ungrounded outlets

  • Condition of insulation

  • Any improper or hazardous wiring

This reveals how much upgrading is needed.

2. Planning

Next, the Bay Area electrician will plan:

Proper planning prevents under or oversizing the new system.

3. Wiring Installation

With electrical power shut off at the main breaker, the electrician:

  • Runs new wiring through walls and ceilings

  • Anchors wires securely along the way

  • Attaches wires to any new outlets, switches and fixtures

  • Connects wires properly at the electrical panel

New complete runs provide clean wiring throughout.

4. Removing Old Wiring

Once the new wiring is complete, the electrician removes exposed sections of old wiring. Any wiring still powering necessary circuits will be left or rerouted.

5. Panel Installation

If required, the new main electrical panel gets securely mounted, and wires get organized and labeled clearly inside.

6. Testing and Inspections

The electrician will:

  • Carefully test all new wiring under load to confirm proper function

  • Have inspection(s) done by the local building department

  • Make any corrections needed to pass

7. Power Restore

With the proper permits and passed inspections, the main power can be turned back on. The electrician will monitor as circuits are switched on to check for problems.

And that wraps up the full home rewiring process! With the electrical system now upgraded to modern standards, you can utilize more powerful devices safely and efficiently.


What Does a Licensed Electrician Check During an Inspection?

Before starting a rewiring project, a thorough inspection by a qualified electrician is crucial. Here are key points electricians will assess during inspections:

  • Amperage – Check the main service panel for 60 amps vs. 100, 150 or 200 amps needed today.

  • Overcurrent protection – Examine fuse boxes and circuit breakers for proper sizing.

  • Grounding – Test outlets for proper grounding. 3-prong grounded outlets are now required.

  • Condition of wiring – Evaluate wire insulation for cracks and exposure that present hazards.

  • Light fixtures – Assess connections, signs of overheating or other issues. Rewire or replace outdated light fixtures as needed.

  • Switches and outlets – Confirm correct wiring without reversed polarity or open neutral.

  • GFCIs – Ensure bathrooms, kitchen, laundry, and outdoor outlets are connected to ground-fault circuit interrupters.

  • Electrical panel – Check for sufficient space and gauge wiring entering the main panel. Add subpanels if needed.

Thorough inspections prevent safety issues and reveal all essential rewiring tasks.
