Pratt & Son

I hired Pratt & Son to replace windows for my condo. The experience was very regrettable.
The owner was incompetent. He did not have the knowledge or professionalism that you expect from a windows professional. While making rosy and unrealistic promises, he was slow to provide relevant information or corrections (which were many). As a result, the project was late, well over budget, and we still did not get the windows as specified in the contract!
The installation itself was also poor. The workers damaged my bathtub, left a mess on the floor, and never bothered to return curtains and blinds back to their places. Most importantly, they did not properly patch cracks resulted from the installation. As a result, there are big ugly cracks around every window.
I sent my complaints to the owner via certified mail and never got a response for more than 2 weeks. After posting a complaint on another site, they replied within hours with unapologetic comments despite clear contract violation and poor work.
A sincerely apology would have been all I asked for. Instead, I am considering further actions.
