Horrible! It was the single worst experience I have ever had with a service provider. They were late, didn't pull a required, building permit, one of the panes was broken before it ever arrived at my home, the window was dropped during installation and was installed anyway, they didn't bring enough supplies for the job and I ended up having to give them some insulation that I already had around, and they didn't bring the proper tools for the job and literally cut the drywall with a sawzall which looks horrible. Note that when the window was dropped, the two guys carrying it had inspected it before they installed it. The first time it rained after the window was installed, water leaked in through the top of the window so I called Hansons and asked them come out and take a look and seal up the visible gaps in the outer siding they had installed around the window so that the leaks would stop. They sent out the guy that headed up the crew that did the work, who of course said there was nothing wrong with the window or his own work and that the leak was coming through the 1 year-old roof I had installed by another company. This was incorrect and was so obviously incorrect that I called the main corporate office to try to get help. Not only would they not help me, but when my boyfriend called the number for Brian Elias that the sales guy had given us in case we ever had trouble getting help any other way, Mr. Elias actually called my boyfriend a moron! I then had both a roofing company and the local city building inspector come verify that it was the window and not the roof that was the problem. I had both of them give me written reports that it was the window that was leaking and not the roof. When the city building inspector wrote his report, he listed 7 separate apparent/possible code violations including that the window was damaged in a way that was consistent with being dropped, that the window was not properly sealed which was most likely causing leaks, that the home was not properly weather-proof because drafts could be felt coming into the home, that the required bulding permit had not been obtained for the job, and questioning whether or not the window had been properly supported when it was installed. After learning that the window which was dropped had been damaged during the drop and that they had installed it anyway knowing it had been damaged, and after receiving the city building inspector's report with so many items being listed on his report, I decided to file a formal complaint with the State of Michigan construction enforcement division. This complaint is in process and the State is telling me that it could take several more months before it is finalized. In the meantime, I thought I should make this post so that maybe others will not have to go through the mess and difficulties that I have had to go through - not to mention the waste of SO much money and time.
