When I bought an older home, I expected some challenges and it was no surprise when the inspector mentioned the knob and tube wiring. Past owners over the years had installed new(er) wiring and even a new 100 amp board, but knob and tube was still running to many outlets.
5 different contractors came in with 5 very different quotes but from the outset I trusted and had a good feeling about Ken Howard. He provided a detailed outline of what needed to be done, how long it would take and how much it would cost.
His crew came in and did everything that needed doing with minimal cuts in walls and ceilings and no contractor drama. They were polite and good natured and I was very comfortable having them in my home.
It was easier for them to work as I hadn't moved in yet and some of the internal walls had be stripped to the studs but with an older home there are always surprises (odd and downright dangerous wiring, strange wall configurations, etc). Despite the challenges and working around other contractors, they finished on time and on budget. They even came back to relocate my electrical box and put the last ceiling light up after I had paid the bill!
HowieCo is now my electrician of choice and I happily refer them.
