My building management requires a COI, which they provided within 24-48 hours after my request, well before the scheduled appointment date. The technicians arrived within the agreed-upon timeframe. They were clean, polite, and spoke English well. They were efficient, cordial, did a great job, and cleaned up nicely before leaving. My windows are sparkling clean! Their price quote was really reasonable for NYC and they did not jack the price up after arrival like some companies do. HIGHLY RECOMMEND!

They kept giving management a date to come and replace the screen but never showed up. They finally dropped off the screen without having staff notify me. So more delays because now they have to "come back" to put the screen back into my window. Meanwhile, the weather is nice and I can't open my window for fear of mosquito bites. Definitely not professional at all. Communication is horrible.

I received a fair price quote within 10 minutes, followed by specific questions - address, I had shared an image of the building, we discussed timing and agreed for payment via Zelle as soon as done.

Work quality was amazing, communication was quick and via text messages even late at night. I have shared the contact with friends and neigbors. I will all my experiences will be the same, and believe these guys will be very succesfull if they keep the customer experience at this level. 5 stars, only because I could not give 6 stars.
