Maybe hire them to diagnose but DO NOT hire them to do the repairs. They charge hourly and their workers run up the cost by making multiple trips to purchase supplies, including days in a row when you KNOW they knew the day before they'd need other stuff. And yes they charge hourly for those supply runs too. Not sure if it's incompetence, poor planning, or intentional to run up the bill but take it from me: do not hire Dr Leaks as contractors.
