Additional Notes

Complaint: June 27 2002. Owner, **** ******* and Son. Had to replace about 4/5 defective windows within a year of installation.The gases between panes were inferior and discoloring the windows. Have had drafts in numerous windows, and when kitchen was remodelled in 2013, my contractor stated that American Thermal never installed any insulation in my two kitchen windows. I believe that is why I am getting drafts in my bedroom and living room windows during the winter with cold air seeping in. There is probably no insulation there either.

Desired Settlement: Would like new windows with insulation as they stated on contract. Will have an inspector on premise when this job is done. I live alone and am female and felt I was taken advantage of as a customer.

Business Response: Initial Business Response /* (1000, 8, 2014/08/04) */ Contact Name and Title: ****** ***** Office Manag Contact Phone: XXX-XXX-XXXX Contact Email: **** Our service man and inspector arrived at Ms. ******'s home on Thursday, July 31st to investigate her claims. We pulled the flashing off the windows we installed and discovered that there was in fact insulation around the windows in the openings. **** showed the customer and she agreed that there was insulation, I have attached one picture to show insulation. That day we put additional foam insulation into the openings, even though there was already insulation existing. We reflashed all the exteriors and recaulked to the brick. There are a couple windows left to complete, which the customer is ok with. We have never replaced defective windows here, that would imply complete replacement. In the past the customer has had glass replacement done due to a seal break in the glass causing the argon gas to leak out. Those are simple warranty issues and the glass is provided by the manufacturer and swapped out in a matter of minutes. It does not mean the window is defective. We discovered while on site that she has a seal failure in one window currently, which will be replaced under warranty. The system would only allow me to add one picture, but I also have pictures of the foam injected around the window and the finished product on file.
