Always like using Josh for windows!
Josh is great. Professional and Does a great job!
Excellent window cleaning inside and out. They are so clean, it’s like the windows aren’t even there!
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.
I was referred to A-1 by our realtor and we are very happy with results. Definitely will be using them again and highly recommend them.
Windows are sparkling clean and gutters clear. Excellent job and will continue to use this company!!!
Josh did an amazing job on my windows that had not been cleaned in 20+ years! He was very friendly, efficient, and worked hard to be sure it was done perfectly. I’d highly recommend A-1 Window Cleaning!
We couldn't be happier with the job Josh did on our windows! Scheduling was a breeze, his prices are more than fair, and he arrived right on time and worked with real attention to detail. Our windows are sparkling clean, inside and out. Highly recommend A1 Window Cleaning to anyone in South Lake Tahoe!
Josh was very thorough and pleasant. He did an excellent job as our windows are now sparkling clean. Thanks, Josh……Jan Todd
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!
Josh and Summer have cleaned my windows in SLT for five years and I’m always happy with the results.
Communication with Josh is easy and quick, definitely recommended!
We contract Josh to clean the windows to our business which is on the 2nd story. He consistently does an amazing job which is pretty impressive since it is located in a busy area. We highly recommend him!
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.
Great job on the windows Josh!! Thank you also for shining up the mirrors inside.The house is even more beautiful now: )
Josh did a great job and we will certainly use him again!
On time, great service, great price! Will use again & will refer others . Thank you
A-1 Window Cleaning and their owner, Josh, do an expert job. We have always been pleased with their attention to detail. Josh & his team want to please their customers. That shows in their follow-up, if once the sun shines directly in a window, we see something that they missed. Josh will make it right! Great guy!…
I have used A-1 Window Cleaning for at least 10 years. I have a small housekeeping service and I always, only recommend Josh & Summer for Window cleaning needs. They are professional and do a wonderful job!
Josh and A1 have done an excellent and efficient job cleaning my windows. I highly recommend him.
Josh and his crew are absolutely the BEST! Professional, punctual and really top notch work! For my family they went above and beyond my expectations! Honestly I feel like we had friends over at the house. Fantastic people who do superior work!🤘
I have been using A-1 Window Cleaning to clean our home's windows for 10 years now. They are professional, respectful, thorough, and trustworthy. I would recommend them to anyone!
