"This was the worst experience i have ever had with a company. They came and damaged my house and kept us without AC for days. They admitted to the extensive damage and went weeks before attempting to repair it. The services were never fully completed and they were paid over 90% of the job. I disputed the last 10% and provided overwhelming evidence of their negligence. And after a year their last ditch effort was to send collections letters. Don't walk, RUN from this company. I will provide pics and my my experience to anyone who is planning on using this company. Used to be family owned and was amazing. Second they sold it went downhill fast."

"Shaun and his guys worked at my house for over a 6 month time period due to a large leak that caused my 2 bathrooms, kitchen and basement to be ripped out. Throughout the entire process he made sure to show up with his guys and walk both my husband and I through what we wanted done and how they were going to do the work. All of the guys that he had work for him were respectful and cleaned up after themselves. They were always on time and also they were very good with my German Shepard puppy who it was not always to keep in contained areas. Throughout the project we kept adding more things on and the whole team was absolutely amazing and always doubled checked with us for all the changes we would make and make sure it was to our satisfaction. I would highly highly recommend this company to anyone and everyone. If you want someone that will answer the phone and be there when things are rough this is the company for you! I don't know what we would have done without Shauns guidance and help throughout this entire process."

Electrical questions, answered by experts

While you can technically live in a home while it's being rewired, prepare for some debris and dust if your electrical contractor needs to remove parts of walls, floors, and ceilings to access wires. If you stay home during the project, ask your electrician to cut the power supply to all exposed electrical wires to keep your family safe.

The color code for the common sprinkler wire is white, and then you can assign the remaining color codes to the rest of the wires for different sprinkler zones. For example, you could use red for the first zone, then blue for the second, and so on.

Color-coding helps you keep track of which wires go to specific zones so that you or a pro can address any issues or repairs quickly. Check your local electrical code for any requirements regarding sprinkler wire colors.

It’s important to ask an electrician a few questions before you commit to hiring them so you can make an informed decision as a consumer. If you’re getting estimates or considering hiring an electrician, ask them these questions:

  • Are you a full-time electrician?

  • Are you bonded, licensed, and insured?

  • What level of experience do you have as an electrician?

  • Can you please share three references?

  • Do you do residential or commercial electrical work?

  • What kinds of electrical work are you most familiar with?

  • Will any subcontractors be performing the work?

  • Are permits and inspections required?

  • Who is responsible for obtaining permits and inspections?

  • What is your schedule?

  • Do you offer a guarantee or warranty on your work?

  • Will you sign a do-not-exceed clause to keep the job within the budget?

Rewiring projects cost anywhere between $1,500 and $10,000 on average, depending on the complexity and the size of the rewiring. You can anticipate spending between $2 and $4 per square foot of wire, including labor and materials. Wire material ranges from $0.25 to $1.60 per linear foot.

Local building codes typically require conduit around exterior wiring. Conduit protects the wire from moisture, extreme temperatures, sun exposure, and harsh weather conditions to prolong its lifespan. When a wire is worn out, it can be dangerous as the risk of electric shock or fire increases.
