Window Cleaner

Our Team:

I’m Greg Thomas, and along with Mike Dyer we are the owners of Streakless Window Cleaning,

I have spent the last 20 years turning window washing into an art form!  

The Streakless style is unlike any other because we created it.  We are expertly trained, hard working, window grime destroyers!

At Streakless, we take our window washing very seriously!  We also are serious about achieving 100% customer satisfaction! 

We pay special attention to treating your home as if it were our own.  We are especially mindful of your pets and all special instructions of our homeowners.  We want our customers to be able to rest assured that everything will be in perfect condition when the job is complete! 

Our reputation is everything to us, and the level of our work reflects this. 

Everyone that comes to your home is an employed member and/or owner of Streakless, Inc. and has a stake in your satisfaction.

Our goal is not to be the biggest window cleaning company in Marin.  Our goal is to continue to be the Best window cleaning company in Marin!
