Read What Happy AHT Wisconsin Windows Customers Think of Our Work!

“I was very impressed in the fact that the crew got here early, it was great! They did a great job cleaning up, they got it all done within four hours, and the quality of the work was very good.”

Barb K. – Appleton Area

“We were most satisfied with the how clean they kept everything and how they cleaned up after the work was finished. It looked better after they cleaned up than when they got there. We love the door and the good quality of the material. We want another couple of doors replaced, we have already spoken to AJ about this. We are also looking at replacing our front door in a year.”

Bob & Sandy B. – Appleton Area

“I think we’ve had 0 degree and below weather with wind chills of -32 below. There was no frost or condensation on the windows. I am very pleased with that.”

Linda S. – Appleton Area

“I noticed right away, that with the old windows the sunlight would come in on the table it would be hot but with the new windows it’s still cold. It’s unbelievable.”

James & Jeanne D. – Appleton Area
