How Much Does it Cost to Rewire a Home in Colorado?

July 28, 2020

Many older homes in the Colorado area will eventually need to be rewired for safety, code-compliance and convenience for the homeowner.

If you are one of those homeowners who needs a whole-home rewiring, you’re probably wondering about cost. In the Colorado area, you can expect to pay anywhere from $15,000 to over $50,000 to completely rewire your home.

Keep in mind that your overall cost will be determined by a handful of factors, including:

  • The size of your home
  • The method of rewiring needed (repair vs full replace)
  • Whether your electrical panel needs upgrading
  • The contractor you choose

We’ll explain exactly how each factor above will impact your overall rewiring cost.

Cost factor #1: The size of your home

Simply put, the larger your home, the more it will cost to rewire.

That’s because larger homes have more wiring that needs to be repaired or removed/replaced. And the more work that needs to be done, the more you’ll pay in labor and material costs.

Keep in mind that if your home has multiple stories, this will also increase your cost. Typically, running wire up and down multiple stories is tedious and increases labor costs.

Cost factor #2: The rewiring method used

If your home has aluminum wiring, electricians will typically choose between 1 of the following 2 rewiring methods:

  1. Repair
  2. Remove and replace

The cheaper option here is to repair the current wiring. When repairing aluminum wiring, electricians will attach a short section of copper cable to the end of the aluminum wire at every connection point (outlets, dimmers, switches, junction boxes, etc.) in your home. This process is called “pigtailing” and is a completely safe alternative to removing and replacing all wiring in the home.

Removing all aluminum wiring and replacing it with copper wiring is the more expensive option because it will require cutting holes into walls and, in some cases, removing walls completely. 

However, not all homeowners have a choice in which rewiring method is used. If the aluminum wiring in their home is particularly outdated and unsafe, repairing via “pigtailing” may not be an option.

Cost factor #3: Whether your electrical panel needs upgrading

If your home’s electrical panel needs to be upgraded, you can expect your overall price to increase by at least $2,500.

In most cases, a whole-home rewiring project will necessitate a main electrical panel upgrade. That’s because older homes with older wiring usually have outdated electrical panels that can no longer keep up with the home’s electrical needs.

For example, many older homes in the Colorado area that need to be rewired also have 100-amp electrical panels. And some homes (especially those built before the 1960s) only have 60-amp panels.

The NEC (National Electric Code) requires that homes today have at least a 100-amp panel but most homes actually need 150- to 200-amp panels to fully power all of the electronics.

Cost factor #4: The contractor you choose

Electricians with more experience will charge higher rates than those with less qualifications and experience.

Although it may be tempting to pick a cheaper contractor, we strongly suggest that you not make price your deciding factor. Instead, make sure that you’re picking a qualified and licensed electrician who has experience specifically in whole-home rewiring jobs.

Going with an electrician who has more experience (vs picking one with the lowest bid) will ensure that your home is rewired correctly and safely, which will save you time and money in the long run and guarantee your family’s safety.

Our tips for choosing the right electrician for your whole-home rewiring project:

  • Ask to see a copy of the electrician’s Colorado license as well as proof of insurance
  • Choose an electrician with either a Journeyman or Master’s license
  • Confirm that the electrician has performed multiple whole-home rewiring jobs in the past 2-5 years
  • Ask for the electrician to provide an upfront quote in writing
