"Matt is our go-to guy on electrical issues.
On this most recent issue, he was able to get us in and do the work within a few days, even though he was almost totally booked with other jobs.
Previously, he updated some wiring in our attic.
He was a referral from our real-estate agent, and has done good work for us.

"WB Lightning Rods happened to be in our area 5 years ago when we had a massive lightning strike and damage to our home. They installed the rods within days of the roof repair and were patient with our questions. Fast forward 5 years, after our recent roof replacement, I asked if they could come out and inspect the rods placement. They are extremely busy due to the stormy time of year but were good about contacting me with updates on when theyâ  d be back in the area. They contacted me when they were in a nearby town, set up an appt for a few days later, showed up to the appointment promptly and spent a generous amount of time, materials, and effort making sure the rods were straight and secure again. Very happy with the service, their professionalism, and work. I recommended them to our neighbors and would definitely have them install rods on any future houses."

"Mr Sherlock did a wonderful installation of lightning protection for our home and ground mounted solar panels at a reasonable price. His knowledge of solar panel lightning protection methods and consideration of our specific requirements made R S Lightning Protection the perfect contractor for this project. Highly recommend this business, prompt, courteous and professional."

Small jobs welcome

"Scheduling with Breeze was super simple and they were able to accommodate my busy schedule. My technician was polite and was able to trouble shoot errors that a previous electrician made. I wish I had used them to begin with. The Generator was Installed in one afternoon too! As for pricing I thought they were average. You get what you pay for though, they do quality work so I donâ t mind paying a little more. Less headaches in the long run!!!"

FAQs for generator repair projects in London, OH

Always start by confirming the pro’s license number, insurance coverage, and experience level. Visit the electrician’s website, scan recent customer reviews, and verify credentials with your local labor department. Request proof of liability insurance and at least two references that you can contact. These quick checks take only a few minutes but go a long way toward ensuring safe, code-compliant work and protecting your home in the event of an issue.

Grouping several electrical jobs into one appointment means you pay a single service-call fee and one set of travel expenses. Instead of asking a pro to return three separate times for outlets, switches, and fixtures, have everything tackled in one visit. The electrician stays productive, and you avoid extra trip charges, often shaving a sizable chunk off the final bill without compromising quality.

DIY electrical work can be dangerous and, in many areas, illegal without a license. One miswired connection risks shocks, fires, or expensive damage. Licensed electricians carry the right tools, follow local code, and know how to shut down power safely before they start. Hiring a pro may cost more upfront, but it protects your home, family, and insurance coverage in the long run.
