"I have contracted exclusively with National Building Services to provide janitorial and day­ maid/porter service to all of my commercial properties, presently totaling some 630,000 SF, for more than ten years. During this period I have been consistently pleased with their performance... ”

"KC and her appointed staff have always been most helpful in providing the cleaning service that best suits our tenants needs in addition to providing updates on the latest LEED related cleaning..."

REATA Property Management, Inc

"National Building Services (NBS) has been providing cleaning services for our two Medical Office Buildings since 2018.  Our total square footage is 192,918 and it takes a team effort to keep up with our newly renovated white floors, elevators and common area restrooms.  Our MOB is high traffic and requires expertise to accommodate the professional look of our beautiful buildings.  

The team for NBS starts with a great leader "Dwayne Spear" who has come in and rolled up his sleeves to assist when needed.  He is a phone call away when time of urgency arises.  Dwayne has put together a great team for our building needs.  We have a day and night team that take pride in their jobs and display commitment to providing excellent service with detailed standards;  from staying on top of the white floors during the day to making sure all trash is disposed of properly at the end of the night and everything in between.  

We are happy with our choice of janitorial services and our tenants and visitors seem to appreciate the cleanliness of our buildings and it's because of NBS and their quality performance and professionalism.  

I would recommend them for your janitorial service.
