  2. Each visit is tracked with AI-monitored checklists and a virtual clock system, giving your company full visibility on every clean.
  3. Each issue is flagged by the system and our team resolves them quickly. So, you don’t have to chase cleaners anymore.

Meet Our Founder

Mark Dunne brought hotel management standards to commercial cleaning when he founded Loreto Group in 2004. Every issue is handled directly by senior management without delays or middle layers. It’s why clients like the OPW, Harvey Nichols and Heritage Credit Union have trusted us with their premises for years.

What Our Clients Say

"We are a large Credit Union, based in South Dublin City, operating from seven branches. We first engaged Loreto Cleaning Services in 2012 to handle cleaning activities in our main office in Rathfarnham Village. Since then we have extended their service to two other offices and intend over the coming year to introduce them into our other branches. You will deduce from this that we have been very happy with the service provided by Loreto Cleaning Services over the past 8 years or so. We have never had a problem with missed days, and any issues arising were minor in nature, and resolved promptly to our satisfaction. Mark Dunne has always been just a phone call away! I wholeheartedly recommend Loreto Cleaning Services and would be happy to be contacted should a prospective customer wish to discuss any of the above."

"I wish to state to whom it may concern that Loreto Group Ltd has carried out cleaning contacts for many years at OPW sites here in Glendalough Visitor Centre , Kilmainham Jail, and other OPW sites. I found Loreto Group to be very efficient, completed cleaning contracts to a high standard, and on time. I would totally recommend Loreto Group to others for any future cleaning contracts that they may require."
