How did we build our business?
Base on Referrals!
A recent poll by 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!?! Get Referral Rewards

Without happy customers, there are no referrals!
Markatos Services Inc. strives to provide the best 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.

Markatos Services Inc. wants to challenge the citizens of New Castle County, DE and Delaware County, PA to try our residential and commercial maintenance services. You be the judge on whether you would refer our services!

" I've been through more than 5 cleaning vendors in my 17 years as manager. Markatos gave the best first impression ever during our first clean this past week!

"I just spoke to the Trader Joe's store in Wilmington, for which you do the window cleanings, and I just thought I would let you know that they are very pleased. They said that whomever you have been sending out for the cleanings is absolutely super - they just love him. He is doing a wonderful job. Thank you very much! Keep up the good work!" - SERVCO

"Harry, I wanted to let you know what a great job Darryl and his crew are doing for us! They arrive on time, are very thorough, and are extremely eager to please.
