5.0 Deanne T. Woodland Hills, CA

Guidio from GMG Window Cleaning returned my call in minutes and showed up (on time) the very next day. He washed windows, inside and out, which hadn’t been washed in years and left them (and the screens) sparkling clean. This was a Christmas present to my daughter, who recently bought the house, and she was thrilled to see the huge before and after difference. Guido is a hard working professional who we have asked to come back on a regular basis for maintenance.

5.0 Christine Z. Studio City, CA

Guido was excellent at the job. Swiftly with a great cleaning process for all 24 windows. He was focused, accurate and fast. I'm hoping he'll come back for other exterior house fix-ups.

5.0 Victoria D. Pacific Palisades, CA

on time, professional, and he did an outstanding job. Experience was excellent and would definitely use again

5.0 Susan H. Pacific Palisades, CA

Guido was very clear in his communications. I knew exactly what everything would cost, and he arrived exactly when he said he would. His work was excellent. He is very personable and a pleasure to have at my home. If you want perfectly cleaned windows quickly and for a good price, Guido, is your guy. I found myself wishing I had more work for him to do. Iâ m going to check their website and see if they do more than windows. He was also very careful and considerate of our pet concerns with open windows - an extra plus. A good guy and a beautiful job.

5.0 Sandra B. Simi Valley, CA

This man is fantastic. I have vistas I didnâ t know were there. This is a new build with all the builder gunk on my winfows. This delightful and personable gentleman did a fabulous job. Iâ d hire him again in a minute and recommend him to anyone. One more note: Iâ m an elderly single woman and had no safety concerns whatsoever

5.0 Lucas T. Thousand Oaks, CA

On time, great work, good price, nice guy

5.0 Yadi K. Thousand Oaks, CA

5.0 Gil C. Los Angeles, CA

5.0 Elizabeth B. Pasadena, CA

Very professional. Good experience! Will use them again.

5.0 Brian L. Los Angeles, CA

I hired GMG Window Cleaning/Guido to clean the outside windows on a rental unit after years of inattention. He arrived right on time. He did quality work. He is super easy to work with. I'm planning to rehire GMG regularly for follow-up cleanings.

HomeAdvisor verifies state-level licensing where applicable - note: some states require local or county level licensing and you should verify whether or not your pro is properly licensed.

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.
