To Whom It May Concern:
In the past 6 months we have purchased several windows form you.
As we are retired, Preservation home specialist has worked with us so we could purchase windows that would considerably cut down our heat expenses.
The salesmen, along with all people involved with the installation of said windows have done everything to make these windows affordable for us to purchase.
Although we have not had use of the warranty, we understand that it is of the best available.
