Super cleaning, including my hard to clean entrance floor. Really impressive.

5.0 Robin K. Olney, MD

The customer service, open communication, and checking in with the client to evaluate the job is a step above other services Iâ ve used in the past. Iâ m very pleased with the work.

5.0 Yanna C. Potomac, MD

We have been using this cleaning service for a few years now and have recommended them to multiple families seeking regular home cleaning. They do an outstanding job with care of our valuables and attention to detail. The staff is always friendly and polite - even to our three young children and our dog! They are extremely responsive to feedback and are accommodating when I have to switch cleaning days. I highly recommend custom services specialists for their professionalism, quality of cleaning services and reliability!

5.0 Sarah L. Rockville, MD

Carlos, Olga, and the team at CSS have provided cleaning services for our family for over 12 years. We truly appreciate the job they do for us. Tuesday has become our favorite day of the week! We are a busy family of 5 and are very grateful to have CSS helping keep our household in order on a weekly basis! We would highly recommend hiring CSS!

5.0 Christopher H. Silver Spring, MD

We've used a lot of cleaners over the years and these are the best. Olga and Carlos are top notch. They are the very best at communicating every aspect of the service, something that is SO important and yet so often overlooked. They remind us the day and time they're coming by, andf they let us know when they are finished. They are dependable, and they do a great job.

5.0 Shawn K. Rockville, MD

Olga and Carlos and their cleaning crew are simply the best. They have cleaned our home for over 10 years. They are reliable and provide excellent cleaning services. Most importantly, they treat our pets like family and are extra careful when cleaning around them. We highly recommend their services.

5.0 Tamera G. Gaithersburg, MD

These are wonderful, trustworthy people who do a fabulous job. They have been with us for years now. We are always very satisfied with their services, and grateful for such wonderful help.

They were really great and efficient! They helped make my life easier! I really liked them! I already recommended them to my sister.

5.0 Jun Z. Potomac, MD

My family really likes cleaning service from CSS. We tried several cleaning companies before. This one is the best. Every time, Carlos sends us a "heads up" message for the next cleaning. Very responsible! Cleaning crew does awesome work every time. We can't live better without them.

Seal of Approval

What is the screening process that Service Professionals go through in order to become members of the HomeAdvisor network?

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
  2. Verify Insurance
    As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.
  3. Verification of State Business Filings
    For business types that require a Secretary of State filing, we confirm that the business is in good standing in the state in which it is located.
  4. Criminal Records Search
    HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business.
  5. Sex Offender Search
    We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
  6. Bankruptcy Search
    We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them.
  7. Legal Search for Civil Judgments
    We use 3rd party data sources to check the principal/owner of the business for state level civil legal judgments entered against them.
  8. Liens Search
    We use 3rd party data sources to check the principal/owner of the business for liens placed against them.
  9. Identity Verification (SSN)
    HomeAdvisor verifies the social security number(s) of the owner/principal for identity check purposes. This check applies primarily to smaller business entities.
  10. Identity Verification (Reverse Phone Lookup)
    We conduct a reverse business phone lookup to identify records matching the phone number information provided by the business.
