"I can't say enough about the team at Cotti-Johnson. From my scheduling with Mel, to the estimate with Ryan and finally, the install crew of Gil, Luis and Nick. Everyone was so professional, courteous and time-considerate. Gil even took extra time to mop my floor to ensure that they left no trace of working in my home! I would recommend this team in a heartbeat."

"We hired V. ISA GENERAL CONSTRUCTION CONTRACTING to remove / deactivate knob and tube wiring and update all our home’s wiring. The service was extremely professional, and far exceeded our expectations. We had a thorough walkthrough both before and after the work was completed, and the company was able to work with us as we made changes during the engagement. Because we had such a good experience with our electrical project we plan to hire them again for additional projects at our home. I could not have asked for an easier group to work with and they made me feel extremely comfortable throughout the entire experience."

FAQs for electrical for home addition or remodel installation projects in Portsmouth, RI

There are several telltale signs that your home is due for an electrical upgrade. You may need to rewire your house if your lights are constantly flickering or your circuit breaker keeps tripping. If you feel mild electric shocks when you touch light switches, hear buzzing sounds, or notice burning smells, you may need to rewire your house, too. Discolored or burnt-looking switches and faceplates are another crucial warning sign. 

Properly installed copper wiring in a residential property can last as long as 50 to 100 years in some cases, but many homes over 30 years old are due for an upgrade. That’s the timeline that many experts recommend, even if it is only a partial update to accommodate technological advancements, increased power demands, and changing safety requirements. 

At $3 to $5 per square foot, the cost to wire a 2,000-square-foot house ranges from $6,000 to $10,000, on average. This can depend on many factors, like the age and complexity of the house and how easy it is for contractors to access the areas they need to get the job done. Opening and repairing walls can further add to your total cost.
