He showed up with an "associate" and determined that the water may be getting into the house through the bricks. His initial estimate was about $5000 to repair, but he kept saying that he has no idea how much exactly until he opens up the wall. Fair enough, I thought, so I agreed for him to open the wall up. He did open it up and then spent about an hour telling me how bad it all looks. He then left and came back the next day with a "brick guy" in tow. Apparently, he needed to break part of the brick wall to do the job right. Throughout all of this, he kept repeating how bad it all was. At this point, I got tired of hearing about my peril, so I insisted that he provided an estimate. After all, the wall has been opened up, right? He continued being evasive but finally squeezed "at least $20,000, but it could go higher". What!? So, we fired him and asked him to send us an itemized invoice for the work done so far. When the invoice finally arrived, I learned that demolishing the wall took about 10 hours between him and his associate. And then, to my great surprise, I learned that he charged 9 hours for "researching on how to do my project without breaking the bricks". There was also mold which needed remediating, but this guy never even mentioned the need to cover it up and call someone licensed in the mold remediation. By the way, his associate's rate is the same as his - $75/hour. So, keep that in mind. He will charge you double the time even if his associate just stands around doing nothing. In the end we ran over $2000 bill with him for day and a half... As for installing the range hood, the guy took 5.5 hours times two (because two of them came) and charged me for 11 man-hours. In the end I paid about $900 to install the range hood.
