I know we have a lot of scary termonology in the plumbing industry, like nipples and elbows, some even scarier like ball cocks, hootie rings and cock hole covers, but what the heck is a "toe tester". I'm guessing it's one of those "residential" things. I'm thinking $200.00 is about tops for cutting a hole in the drywall, securing what's loose and then patch and piant. Installing an access door is a good idea, but that only reduces your costs for the next visit. Look for an estimate that's not much more than this. Use your judgement. Hire someone that has an office, trucks, real employees and all that stuff. Stay away from the guys that hang out in front of Lowes or Home Depot. Labor 2hrs. minimum $80.00 Materials $25.00 Truck Charge (Tools) $45.00 Taxes $12.50
