# Whole-home rewiring Services Aluminum wiring, cloth wiring, too few circuits for a modern kitchen. We rewire room by room with minimal disruption and patch as we go. Request this service[(925) 535-8805](tel:+19255358805) In short TopTech Electrical, a licensed Livermore electrician (CA #1138519), rewires whole homes room by room to replace aluminum, cloth, or otherwise outdated wiring. Permits and inspections are part of the job, and the work is patched as it goes. About this service ## Whole-home rewiring: what to expect Whole-home rewiring means replacing the electrical wiring throughout a house. It usually makes sense when the existing wire is old, damaged, or can't handle how a modern home uses power. At TopTech Electrical in Livermore, we rewire room by room, so most of the house stays usable while the work moves forward. What's included - Site visit and free written estimate - Electrical permit filed with the city - Room-by-room rewiring to limit disruption - Rough-in and final inspection coordination - Patching and finish work as we go - Licensed (CA #1138519) and insured - ### Signs your home needs rewiring Homes built in the 1960s and 1970s often contain aluminum branch wiring, which can loosen at connection points and overheat. Older cloth-insulated wire is another common problem. Many older kitchens also lack enough circuits for today's appliances. Warning signs include: - Outlets or switches that feel warm or look discolored - Lights that flicker or dim when a large appliance starts - Breakers that trip repeatedly - A burning smell near outlets - ### How the job goes We start with a visit to check the panel, the wire types, and how many circuits the home has. You then receive a free written estimate. Once you approve, we file the electrical permit. New wire is run through the house, and the inspector checks it before any walls or ceilings are closed. After devices and fixtures are connected, we patch and finish the surfaces we opened and schedule the final inspection. - ### What affects the cost The size of the home, the number of circuits, and how many walls and ceilings must be opened all matter. Attic and crawlspace access, the condition of the panel, and the finish work also play a role. Adding circuits may mean checking whether the existing service can carry the new load, and a panel upgrade may be part of the plan. Your written estimate lists these items before work begins. - ### Permits and safety In California, rewiring requires a permit, and the building department inspects the work before final approval. Inspections protect you by confirming wire sizing, breaker matching, and grounding. Aluminum wiring is not always a full rewire: approved aluminum-to-copper connectors can make some homes safe, and we will tell you which option fits your house. Reviews ## What your neighbors say.

He was also the only one ensuring we get a permit and do everything the right way.” Ivan Llanos - Same-day service > “TopTech Electrical was incredible. Alex was very responsive and came out same day.” Kristina Rocha - Panel safety > “Outstanding service. Alex pointed out a potential electrical safety hazard in our home, an old and potentially unsafe circuit breaker box. There was absolutely no pressure, nor any false up-selling. TopTech will be my number one for electrical repairs.” Sanford Weitzner - Breaker & kitchen lighting > “Alex took the time to explain the installation process and diagnose the problem with our broken outlet. Alex and the TopTech office were great about communicating and keeping me informed.” D Mark - Emergency repair > “Within 5 minutes we had a call back. He came out later that afternoon, same day. He worked hard for three to four hours in extreme heat and small spaces and was done by 4:30 for a very reasonable price. His professionalism was unmatched.” Tammie Piveronas, Livermore - Doorbell transformer > “He quickly diagnosed that the real problem was a faulty transformer. What impressed me most was the level of care he put into the work. He spent just as much attention cleaning up afterward as he did solving the electrical issues.” Steven Du - Recessed lighting > “They installed recessed lighting quickly and did an excellent job.” Tricha Mata - Returning customer > “Alex came out to us in Brentwood just a day and a half later and provided a thorough estimate with options. We scheduled the service for the literal day after. The estimate was very reasonable, fair, and just.” Paul Soper IV, Brentwood [Leave Google Review](https://search.google.com/local/writereview?placeid=ChIJjUO3M0x2mgsRkmNF4TG_1UY)[Leave a Yelp Review](https://www.yelp.com/biz/toptech-electrical-livermore) Emergency service ## No power?

What people ask before they book. Text us anything else. **Do I need a permit for whole-home rewiring in California?** Yes. Rewiring projects require an electrical permit, and inspections are needed before the work is approved. **Do I have to move out during rewiring?** Usually not. We work room by room to keep most of the house in use, though the room being worked on will be disrupted. **Does all aluminum wiring need to be replaced?** Not always. Some homes can be made safe with CPSC-recognized COPALUM or AlumiConn connectors, while others need full rewiring. A licensed electrician can inspect the wiring and recommend the right option. **Will you repair the walls after rewiring?** Yes. We patch the surfaces we open as we go, so the house is finished when the job is complete. More services ## More ways we can help.
