Core Cleaning is independently owned and operated and fully insured for both residential and commercial cleaning services. It has been owned and operated by Karen Marth since 1990.  Joined by her 2 daughters, they have devoted themselves to providing reliable, consistent and Eco-friendly services, that allow them to take exceptional care of their clients and the environment.

Karen owns Core Cleaning and is passionate about high quality, Eco-friendly, customer convenience focused service and has become known in the Durham Region as “The Queen of Clean”.  When Karen was 20 years old, she had a 3 year old daughter and she just knew that she didn’t want to leave her with a babysitter when she had to go to work, so she bought an existing company, picked up the White Pages and a phone to grow this company. Call by call, now 30 years later, we have become the #1 Cleaning Service in Durham Region – Core Cleaning.

When deciding to operate a business, Karen wanted to not just work, but she wanted to help people. Most families now have dual income, they have to balance their jobs, families, kids and household chores – Something has to give, and its typically spending time with our families to do chores instead.

Core Cleaning allows over 100 families every week to free up some space and time in their schedule, to focus on what matters most to them. It doesn’t matter who you are, when you come home to a sparkling home that someone else cleaned, you feel good and your family feels good.

At Core Cleaning, we are so much more than just Housekeeping. We have created a way for you to get those more expensive Specialty Cleaning Services that can dramatically increase the value of your home, with a payment plan that can allow you up to 12 months to pay. 

When you invite Core Cleaning into your home, you can rest assured that you will get a detailed cleaning, to the CORE of your home.  We respect your home and your time as if it were our own.
