In 1983 Susan Markatos founded Markatos Services Inc. The company began as a small local residential cleaning company based out of Wilmington, DE. In February 2004 Harry Markatos joined the company as part owner, creating a family owned and operating business. The company grew within the next few years, offering commercial cleaning, window washing, pressure washing and handyman services. Markatos Services Inc. now services New Castle County, DE and Delaware County, PA. 

Markatos Services Inc. is an "old school" cleaning company. We don't beat around the bush when it comes to serving our customers. We are NOT a franchise. We treat our customers like family because we put our family name on our business. 

You will fall in love with your home or office all over again. Why? We're "old school" when we clean. We are NOT a maid service; we are a CLEANING SERVICE. We don't dust your house and then leave, we thoroughly clean your home from top to bottom. 

We get on our hands and knees to clean your floors.
Scrubbing tile floors on your hands and knees is more effective than using just a mop. Getting low to the floor helps us pick up more dirt and sticky messes that a mop can brush over. 

We don't spray and squeegee your windows.
We wash them by hand.

This is a more successful way to clean windows, leaving them spotless. Squeegees can leave spots of compressed dirt and grime. Scrubbing these areas with rags will remove built up dirt.

Markatos Services Inc. is a professional cleaning company with a personal touch, an "old school" touch. For 30 years we have gone above and beyond to make homes shine.

"Happy to be celebrating the 20 years that we have been with you. Would have been thirty, but we didn't live in DE then." - Charlie, Eddie and Jordan

"What I like most about the Markatos is that they are a family business. They answer their own phones and Susan, Harry and Nicole work with their crews. They have always been accessible and I feel like they really want to do a first rate job for their customers. How often does that happen these days?
So, congratulations for 30 years and best wishes for the future!" - Susan N.

"Dear Markatos Family: Congratulations on 30 years in business. I am a brand new customer who just had an initial cleaning. My house looks beautiful! The team that came to clean, were friendly and incredibly hard working. It was a pleasure to meet Nichole again when she came to check the house before the team left.

Both of you have achieved great success in building this business. At the same time, I sincerely love both of you, and Nicole as well.
Nicole is stepping into your shoes, and you must be so very proud. You are all such great professionals, and all have exemplary character with big hearts. Many congrats!!!" - Cora P.
