Progressive could do both. From my initial call to the arrival of the electrician and plumber, I couldn’t have been more pleased. … I would use them again and highly recommend them for your ‘mechanical’ needs. - ### Review from Wendy L. ### Wendy L. ★★★★★ Everything was taken care of today. They were just amazing. They got everything done real quick, no mess, real polite. They were just awesome. … The best news we’ve had since we’ve moved into this house. - ### Review from Lee & George H., Wake Forest ### Lee & George H., Wake Forest ★★★★★ We really appreciate the extra time, phone calls to the supplier, and careful reading of the instructions to do the job right.
