Caveat Emptor‎ -This business I have had only 1 experience with, and it was very poor. Their plumbing inspection was for one specific item, which was incorrectly diagnosed. The company which had originally hired them had to contact with a different [and reputable] contractor to complete the inspection.To add insult to injury, Johnson's had the gall to criticize some HVAC work done in my home - AND left a service sticker on my furnace to boot!Avoid at all costs - dishonest to the point of fraud.
