Copper State Home Builder review: Scam

Choose ANYONE ELSE! Copper State was requested by a plumber my mom hired to fix her dishwasher. My mom ended up buying a new dishwasher but had this plumber install a PRV at his suggestion (amongst all sorts of other suggestions she did NOT hire him for). This plumber said it would cost $300. The job ended up costing $1269 and he charged her card the next day for $3500 with no invoice or explanation (police report and ROC complaints have been filed). During this work, the plumber claimed there were multiple leaks in her bathroom wall, called Copper State to rip her bathroom apart. Prior to doing that, Cooper State tested for lead and asbestos (which left a chunk out of her wall), scanned her bathroom walls with a thermal imaging gun (which apparently is broken as it detects things that AREN'T there), they ran fans/dehumidifiers for two days to dry out a supposed "active leak"... anyone else think that's weird? My mom was told by the plumber that this all of this would be covered by insurance. That's when she let my husband and I know what was going on. My husband raced over to her place and was trying to make sense of what was going on. When he asked if the plumber had used the access panel to see if he could locate and repair from there instead of ripping apart her bathroom, he said that was "impossible". At this point we realized that no party provided my mom with an invoice or explanation of costs or potential costs to her. We stopped any further work and had our plumber come in for a second opinion. Her bathroom never smelled or showed signs of any leaks, so it seemed strange that after hiring the plumber to help with her dishwasher, that her bathroom was now going to be ripped apart. When we called our plumber, they informed us that they NEVER do work without giving a thorough itemized quote of work to be done and would get a sign off before ever starting any work. Our plumber spent 1.5 hours looking over the area, going into the access panel that apparently the plumber and Copper State couldn't operate (taking some screws out is too difficult for some to look into before doing completely unnecessary work). Our plumber wrote up a very detailed report that no evidence of a past or present leak was found. During our investigation, we've found that the plumber my elderly mother hired is operating without a license and yet Copper State is willing to do work with him?! To blindly accept his claim of leaks without doing ANY basic inspection of their own?! To rack up a bill for my mom of over $2700! To boot, their itemized bill is ridiculous. They have a charge for emergency services. This wasn't an emergency! It was even a THING! THERE WAS NO LEAK! Running their THERMAL IMAGING GUN which apparently is the biggest scam ever! They charged for plastic sheeting, which wasn't used. I could go on and on. What this boils down to is INSURANCE FRAUD and taking advantage of an elderly woman. Both are extremely sick and not something a reputable, honest and ethical company would do. As stated before, use ANYONE but Copper State to do any work you need.
