Hired on Thumbtack
A nearby tree was struck by lightning and the surge came into our house. Fire department cleared the scene and shut off our main breaker, and we were left with no idea what was safe to turn back on.
I found Demmons Electric on Thumbtack and they called me back immediately. Jake listened to what happened, understood it couldn't wait, and committed at 6:32 PM to coming out that night. Jake and Hunter both showed up and didn't leave until close to midnight, they inspected the whole system, made the damaged circuits safe, brought the load back up gradually while watching for problems, and tracked down a fault in our basement lighting circuit. They rigged a safe temporary fix so we had lights, then came back to do the permanent repair.
A few things stood out:
Documentation. This was an insurance claim, and their write-ups were thorough and accurate. That kind of detail matters when you're dealing with an adjuster.
Fair pricing. Materials were billed fairly. The repair estimated 6 hours and came in at 6 hours.
They didn't disrupt us. We both work from home. They pulled a new line to a bad switch and installed a whole-home surge protector without interrupting our workday once.
Communication. They found our ceilings weren't mounted to strapping, which meant drilling many access holes to fish the new cable. They stopped, explained it, made sure I was okay with it, and minimized what I'd have to patch. That's on my builder, not them — and I appreciated being asked instead of them just proceeding.
Here's my real endorsement: most contractors I hire disappoint me badly enough that I never call them again. I would absolutely call Demmons back.

These guys are very professional and responsive. They arrived on time on a very short notice. Made a trip to the hardware store to get the right part. Billing was reasonable. I’d highly recommend them for any electrical work.
Demmons responded promptly to our service request and diagnosed and resolved the problem the same morning. We intend to engage Demmons for an additional project we are planning in the coming months.

They did great work replacing most of the wiring in our 1950s house, and were very communicative and professional! Thank you!
