I used John the electrician twice. Both time they did excellent job. They did up grade the old wires up to codes, very reactive, saved me a lot of money.
Second time they did troubleshooting in another house, corrected all the improper splices and the failed one. Problem solved
The price is very reasonable.
I am highly recommend the company.
