The Company
Owner and Founder, Susan Markatos cleaned homes for over 30 years. Her cleaning expertise and professionalism has expanded our house cleaning services to include office and large commercial facilities as well.

How did we build our business?
Base on Referrals!

A recent poll taken by Markatos Customers showed that 97.2% of our customer base comes from referrals and word of mouth advertising. This means our customers must really like our services!?!

Without happy customers, there are no referrals!
Markatos Services Inc. strives to provide the best cleaning and maintenance services in New Castle County, DE and Delaware County, PA. By holding mandatory training sessions for employees on a weekly basis we are able to produce consistent high quality service to all of our valued customers. The foundation of all positive word of mouth advertising is providing superior products and services. Our goal is to do just that!

Do you ask friends or family first? 
A referral from a family member or friend has a huge impact on ones decision-making. Whether you are deciding what restaurant to take your wife to for your anniversary or which cleaning service you want to go with; a referral goes a long way. People are not going to refer you to a restaurant or service provider that they haven't gone to or used themselves. This is why referrals are the most trusted form of advertising.

Would you refer our services?
Markatos Services Inc. challenges you to try our cleaning services. You be the judge on whether you would refer us!

Our Work Ethic

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. We go above and beyond to make your home shine.

“The girls did a fantastic job of cleaning everything in the house! I especially appreciated the final check done by Jerome at the end to ensure everything was done correctly.” – Stephanie K.

“Great job and attention to detail. Thank you!” – Barbara D.

“Sam & her team are great, and our little dog "Mei-Ling" loves them. They made the house look great.” – Sandy W.

“When you use tooth brushes and your cleaning team is on the floor scrubbing, that's a sign that your cleaning company is the real deal and you mean business. We would highly recommend your services to anyone. Thank you so much for doing a great job.” – Teresa P.
