Thank you again for all the support and superb response by North Hills regarding the roof leak. The cleanup was shear perfection with the immediate labor and quantity of equipment brought onsite.

Great company. Been using them for many years. Always delivers great service in a professional and timely manner.

North Hills Office Services is my go-to company for all my building maintenance needs. They are very professional and responsive. We had a major flood from the 2nd-floor sprinkler line and flooded all the way down to the lower level at 10:00 pm on a Friday night. All it took was one phone call to North Hills and a team of people showed up 1 hour later with equipment to clean up the flood and remove debris. Thanks to their quick response we were able to open the building Monday morning. No wonder why they’re in business for over 47 years. I would recommend North Hills to anyone who owns a commercial office building.

We have been using North Hills Office Services since 2009 and I must say there is no other company I would recommend more. We have a large portfolio in the Metropolitan New York area of Class A office buildings. We not only use North Hills for our janitorial services but our handyman services, construction cleanups and most recently acoustical ceiling restoration. This company does it all! North Hills Office Services is an asset to our team. Their professionalism and expertise help us meet the high expectations of our tenants and our buildings always look clean and tidy.
