"Flora and her crew did a phenomenal job with the deep cleaning I ordered! The last tenants of this place ordered cleaning, but there was still dust in the vents and lingering food scent. Flora and her employees exceeded my expectations and cleaned every nook and cranny, including the doors, which still had some crayon marks. I’ll definitely be using their services again. 5 stars!!!"

"Purchased the Angie's deal coupon for $250 for full HVAC cleaning and all vents and returns. During cleaning they found some black mold and recommended deep cleaning for additional $250. They showed us pics of where the mold and other dirty stuff was and we decided to have them clean it since I doubt duct cleaning was ever performed for this house. We were satisfied with the result. The cleaner was prompt and explained everything in detail. We were satisfied with the service.

"They have been cleaning for us for several months now, and their work is consistently excellent. Lily the supervisor is available by text and phone to go over what's needed, and she sometimes stops by to check on how the work is going and to discuss long-term cleaning plans. I am very happy with their work! The cost quoted below is the price per person/per hour."

"They are the best cleaners I have ever seen. I am 80 years old and I used to clean houses myself after I retired from the florist industry for 40 years. I cleaned 2 secret service agents homes for 4 years. I also cleaned 4 other homes. I earned about 15 hundred per month."
