Buyer beware!!! I contracted Bill McIntosh to hang two Alside attic windows which he installed on the rest of the house for the previous owners. He charged $500 per window and did not complete the outside trim. I called him several times and left messages to no avail. I then contracted another Alside contractor who advised the windows should have cost $283 each, not $500, and that they were actually Loranger...a cheaper window than Alside.
