Janitorial reviews in Washington, Maryland

We are so glad we chose Costina Cleaning Services for the move-in/move-out service for our investment property. The apartment is spotless, and the team was very responsive. Sam provided customer service. We would definitely choose them again!

I have been extremely satisfied with Team Sofia. She does an outstanding job, and the feels amazing after her cleaning. Sofia is always punctual and has been very flexible with date changes Additionally, Costina Cleaning Services provides excellent customer service, responding quickly to inquiries and making it easy to adjust bookings. I highly recommend them!

Kabi came and did a very thorough and professional job on our carpets and couch. Kabi even tackled an old rug that I thought I would have to take to the dump. I have had it cleaned by another company but the stains were still there and, being light grey, I thought it was ruined. Kabi took to it with his big new machine, and honestly come up a treat! We are very grateful! Customer service was outstanding and I will surely be recommending Costina Cleaning Services
the future. Thanks again!

​Hi there! I know when your team is busy working or it's late at night, it is impossible to answer every ringing phone.

​I set up a friendly 24/7 AI voice receptionist that answers every single call, so nothing ever goes to voicemail. Your customers get to talk to a completely natural, human-sounding AI that answers their questions and books the job for you!

​Would you like me to add that quick line at the very bottom asking if they want to click a link to hear a short sample of the human voice?

We booked a last end-of-lease clean Costina Cleaning Services and they were responsive and helpful in providing a quote and arranging a team. The cleaner was fantastic! They thoroughly cleaned our house, and we truly appreciate it. The place looks brand new! I highly recommend Costina Cleaning Services for anyone in need of an end-of-lease clean. Thank you, Costina Cleaning Services!

Very impressed with the recent clean of our carpet. Sam and his team did a brilliant job getting back to brand new carpet. They were prompt, professional, did a great job and excellent value for money. Sam was even happy to oblige last minute to include the cleaning of our cushions rather than just the frame as originally requested. Will definitely use Costina Cleaning Services again.

I had my apartment cleaned by Team Sofia and Carla, and they did a fabulous job! My one-bedroom, one-bathroom apartment, including the fridge, was immaculate. I truly appreciate the effort they put in. The team was punctual, arriving right on time, and they were extremely professional and polite. The place was spotless after their cleaning. I will definitely invite them back again. Thank you!

My couches and carpets look brand new again! Thanks, Kabi and Sam for the super friendly and professional service. It isn't hard giving a 5-star rating for your work; the end product is amazing. I can't wait to get my tiles done in a couple of weeks. Highly recommended, your prices are fantastic, and the quality of work is second to none. It's an added bonus supporting a local family business too. Thanks again.

The team from Costina Cleaning Services is wonderful! The booking process was seamless, and I received a couple of reminders before the appointment with the option to reschedule if needed. The cleaners arrived on time, did an amazing job, and left the house spotless. I highly recommend this local business!

A year ago, it's clear why Costina Cleaning Services comes highly recommended! As I am pregnant want to avoid using chemicals right now, I decided to book a house cleaning. Sofia and Carla just finished deep cleaning my two-bedroom apartment, and I'm incredibly with their work! It’s spotless, smells clean and fresh, and is even cleaner than when I moved in! The bathrooms were my main priority, and they are sparkling. The kitchen and stovetop, where I cook, have also been thoroughly cleaned. Honestly, the entire house is perfect. You can tell that a lot of care went into this service, and their attention to detail is incredible. I plan to book regular cleanings moving forward! Thank you so much!

The service fantastic! Although I wasn’t there my sister mentioned that the cleaners were friendly efficient, and very helpful.

Green Apple Commercial Cleaning has earned my business! They left my office looking and feeling amazing! Great job!

Great experience from start to finish. Office staff is amazing, kind and friendly, the cleaning staff is prompt friendly and very detail oriented. Could not be happier. Thank you to the entire staff at Green Apple.

Owners and staff are the ultimate professionals. We were in a bind on a tight timeline to get a commercial facility cleaned in short order. Green Apple was able to deliver exactly what we were looking for exactly when we needed it. I have used their services again since then and have been able to rely on their support regularly. Thank you!

I had a wonderful experience with Green Apple Cleaning DC. Patryk and his team came through in the clutch when I needed a reputable company to clean my office. The estimating process was easy, and they took the time to hear what my priorities were. That really goes a long way for me. Their price was better than that of other companies I had used in the past - but there weren't any added "extras" (finally!). Fully transparent pricing and their quality of work is fantastic. I will definitely use you all again. Thank you!

I own a shopping center with restaurants and retail shops in Baltimore with 75 employees and have tried a number of cleaning companies. Green Apple Commercial Cleaning DC has been, by far, the best cleaning company I have ever had. The staff members are professional, punctual, meticulous, courteous and dedicated to their jobs. No cleaning job is too small or unimportant to them; and they never leave any area unchecked or undone. I love their thoroughness and perfectionism. I often receive compliments from my customers for outstanding cleanness of my restaurants and retail shops. Their work speaks for itself. And, that is why I have been extending my contract with Green Apple year after year. I know I am with the best cleaning company in MD/VA/DC. I highly recommend Green Apple for any cleaning service. The right cleaning company you choose will determine how you project the value of your company, building or house.
