Josh and his helper did a fantastic job on our windows. We’ve got 2nd floor windows and a few of them are at difficult angles and that didn’t present any problems for Josh. I would highly recommend A1 for your windows. The price was very reasonable also.

Thanks, Josh! I thought I was going blind, but it was just our dirty windows! I can see clearly now! Thanks for a fantastic job on all of our windows -- the colors of Spring in Tahoe are even more vibrant! You did a fantastic job; I can't recommend you enough! Fast, efficient and courteous.

Very happy with the efficiency and quality of their work. The price was fair and comparable to what we've paid other companies in the past...but they were much more responsive overall and we will use them exclusively in the future!

Excellent! That word sums up Josh's quality, attitude, and value. He cleaned all windows inside and outside of our 2-story house, in just over 1/2 day. And they looked great: no streaks, no missed sections. Moreover, he offered several pieces of advice that will help us going forward. We will definitely use A-1 again.
