I am a small town handyman who wants you to feel joy in your home. Whether it is a faulty switch making you nervous, a ceiling fan or lighting fixture that has out-stayed its welcome, leaky pipes causing damage, or even a doggy door installed.

"Mr Sam did a wonderful job removing a bad water heater and installed a new one. He also reconfigured my plumbing under the kitchen sink and installed a new sink and faucet. He was on time, polite, patient with my son who asked a million questions, and left a tidy workspace when finished. I am excited to hire him again for my many other projects that are needing done. I highly recommend this company. "

FAQs for electrical wiring or panel upgrade projects in Union, MO

Electrical wiring can last between 50 and 70 years if properly installed and maintained. However, factors like moisture damage and overloading outlets can shorten this lifespan. To extend your wiring's life, unplug electronics when not in use, avoid overloading outlets, and schedule regular electrical inspections every five to ten years.

If your house was built in the 1960s and hasn't been rewired, it likely needs it. Older homes may have outdated wiring like knob-and-tube, which poses fire risks due to flammable insulation. Rewiring ensures safety and may also require updating your circuit panel, outlets, switches, and fixtures. Contact a local electrician to help with your rewiring needs.

Yes, rewiring your house is worth it, especially if your wiring is outdated. It improves safety by reducing fire risks and can increase your property's value. However, you may not need a full rewire. A home inspector can tell you if a partial rewire will bring your home up to code.

Yes, you can sometimes rewire a house without removing walls. Electricians might access wiring through attics, basements, or crawl spaces, or make small holes to run new wires. However, this isn't always possible, and in some cases, removing sections of walls is necessary to ensure the wiring is installed safely and meets code.

A house should typically be rewired every 25 years to maintain safety. Over time, wiring deteriorates, increasing fire risks. Regular electrical inspections every five to ten years help assess the need for rewiring. Staying proactive with maintenance ensures a safe, efficient electrical system and prevents potential hazards before they become serious issues.
