Deer Park, NY 11729

To Whom It May Concern,
This letter is being sent to acknowledge two employees from your company who recently installed a
Patio Door at my residence on Wednesday, November 16th. While I am unable to recall their last
names, their first names are Melvin and Douglas. Both of these individuals arrived at my residence at
Underhill Avenue, Bronx NY and found themselves challenged in removing the patio doors that
were installed at the property and were uncertain if they would be able to given the way the doors were
originally installed and the blots that were used. After examining the door frame further, they did not
give up but, tackled the challenge with the utmost diligence and professionalism.

To my amazement, they not only removed the original doors, but assembled the new door and framing
outside in the rain and cold weather without complaining; a true testament to their dedication and skill.
I cannot express how very pleased I am to have my new patio door installed and the debris from the
previous doors removed . These two gentlemen are certainly a valuable asset to your company and I
can only hope that others recognize their efforts.

Sincerely,

Ms. Delia R Cruz
