Phenomenal service. Leo and his team were top-notch. Scope of work was all windows, solar panels and power washing of some stains. Results were terrific and will Wintech/Leo back next year!

I have noticed over time that my solar panels were getting quite dirty & the electric outputs on my monthly NEM statements were going down significantly (as my electric bills began creeping up)!!!!
Just today, Eddie from Wintech arrived promptly on time & thoroughly cleaned all my panels ….the before/after photos were totally incredible. So clean, they were actually reflecting the images of the trees off the surfaces! I would highly recommend Wintech….extremely fair & competitive pricing, excellent work, very courteous and hard working group!!!

Leo took the time to carefully clean my solar panels. I’m super impressed, but not totally surprised at the immediate increase in solar generation. The highest readings I’ve gotten prior to his visit today, have been 5.8-5.9 kW on super sunny days. I’m now seeing upwards of 7.0kW, or a 20% increase! We’ll be doing this with Wintech on a regular basis from now on! Thanks again. Great job! (-:

Leo came right on time as promised. He worked tirelessly for close to two hours deep cleaning 19 panels. I used to only get roughly in the high 3’s kW and on a good day and on rare occasions, I would get 4.3-4.4kW with sun shining directly over the panels, briefly. When he was done cleaning, I immediately got the max of 4.8kW and I wouldn’t even consider today sunny. The panels now look dark blue as opposed to brown previously, lol. Thank you Leo!

Wintech window cleaning. Just used him today! One guy, Leo he did an amazing job. He arrived promptly at 9 am. Was here til 2:30. Screens, windows inside and out. Glorious job! Now the windows look crystal clear from the inside and like a mirror from the outside, so clean. I will use him again and would refer his business.

Leo and Eduardo were very great with communicating and adjustable with our family’s schedule. Both guys were super nice, respectful and great with our pets. Our windows look great both inside and out, and they were very quick. Probably the best price out there – would hire again without question I highly recommend!

Leo has been cleaning my windows for the past three years and he always does a great job. We have a two story house with a lot of windows and he does them all, no problem! He even did the windows in the garage, he’s super thorough! He’s professional, polite and a sweet guy! This year we added the inside of the windows, and my windows have never been this clean, it makes such a difference! He even wore shoe covers when he was in my house to keep my floors clean, I appreciate his thoughtfulness.

I’m thrilled to share my incredible experience with Wintech Window Cleaning! Leo and Eduardo went above and beyond with their window cleaning and Christmas light installation services. My windows have never looked clearer, and the attention to detail is remarkable. Leo and Eduardo’s expertise truly shines through in their work. The Christmas light installation was a game-changer during the holidays, transforming my home into a festive paradise. I couldn’t be happier with their service and professionalism. Wintech Window Cleaning is now my go-to for both sparkling windows and stunning holiday decor!
