Excellent service. I had the Deep Cleaning done & Gladys went above and beyond with cleaning my apartment. I was completely satisfied with her work. I will be using the service at CCS Cleaning for now on. I recommend this Cleaning service.
If I could give 20 stars, I would!! Customer service was very clear in the details of their services and were able to book me for the next day. The cleaners were on time, very kind and considerate making sure I wouldn’t have allergies to their products, and went above and beyond. I’ve been having severe allergies…
This was my first experience with a moving cleaning service, it was for my parents house and considering how many things they had just lying around for years keeping dust, the windows upstairs that no one maintained and such, it looked like a completely new house at the end!
Deep cleaning was not worth the money. I decided to give them a second chance even though my wife asked me not to. Each time I received a different cleaner with widely different levels of attention to detail. They finally sent a cleaner that made a huge impact on my household and by this point I realized that their…
My first cleaning went great. Gladys was very thorough and did everything I requested. The next cleaning i requested her again but she was unavailable so I got a replacement cleaner last weekend. I was very dissatisfied. She brought her teenage son with her who poked around through my stuff, there were tufts of…
I recently had Lucia come in for a one-time deep cleaning. She was friendly, professional, thorough, careful and quick. I was amazed how quickly she worked. Looking forward to having her back. The company has great communication and friendly customer service. Highly recommend.
Absolutely terrible experience with Crystal Cleaners. I hired them for a $400 deep cleaning because I needed the property cleaned and ready to rent out. Instead, they barely cleaned one room and left the rest of the house disgusting. There was still dirt all over the floors, dust packed into the vents, stains left…
Our place was a project, Dina and her helper did an amazing job in the time they were here. Thankful that they took on the challenge of our kitchen and bathroom along with everything else 🙌🏽
We had a wonderful experience with CCS! We were in need of a house reset and they did such an incredible job. They were friendly, communicative, and super flexible on top of just being great at their job. Price was also great for a deep clean since our house is on the larger side. 1000% would recommend and we will definitely book again.
Amazing work! My house has never looked/smelled so clean. She was here over 6 hours and didn’t miss a thing. Every detail was taken care of. I’m looking forward to her next visit already!
I hired Crystal for a deep clean based on all of their great reviews and how their website advertised attention to detail, but the service I received did not match that. When I came home, there was still visible dust on counters and other surfaces, including areas where small objects could have easily been moved to…
The deep cleaning was great.
I had a deep cleaning performed by this company. Two ladies did such an amazing job with everything from top of my cupboards to counters to baseboards. The price was very affordable- I highly recommend!
Norma and Alicia were great and efficient. They did a good job. They work great together. I thought it was 1 person coming and it was going to take all day. They finished in 3 hours. They were professional.
Wonderful experience. They were on time and did a fantastic job. I would definitely use them again.
Norma was great, so thankful for a little extra help after starting to work again with 3 children under 4!!!
The ladies were detailed and took care of everything I couldn't do myself. Very pleased
This cleaning service is very efficient. They are professional and completed the service to my standards. I would recommend using them and will use them in the future.
On time, hard working, attention to detail, professional, and friendly. Hired them for a deep cleaning service of a 3300 sq ft home. Betty and Cesar performed an excellent job. They stayed late to finish the job and did not leave until I was 100% satisfied and encouraged me to take a look as the cleaning progressed…
I’m happy with the deep clean! The house looks amazing, and every detail was taken care of—especially the bathrooms and kitchen. Very thorough, professional, and efficient. I highly recommend their deep cleaning services.
