I have been a longtime customer of John Moore, but after my recent experience with one of your plumbers I may not be one in the future. I had a small drip of one of my bathroom faucets and called for an estimate. Your technician quoted me the outrageous price of $700.00. I am a Senior Citizen and that would be more than half of my social security check. The little rubber gasket probably costs less than $1.00 to fix this. Luckily I found another licensed plumber, who repaired it within 15 minutes for $100.00. How do you justify the quote of your plumber?
