About Us

At Sealco®, our mission is to keep data centers and clean rooms running at peak performance by ensuring that they are contaminant free, uncluttered, and most effectively managing airflow for optimum equipment cooling and energy efficiency. We do this by: 1) Offering world-class, uniquely specialized data center and clean room cleaning services (both on-demand and on a preventative maintenance basis); 2) Designing, providing, and installing Sealco’s own AirSeal® bypass airflow hot aisle/cold aisle containment systems; and 3) Offering the very best data center and clean room products.

Our History

Ron MigliniWhen Ron Miglini first founded Sealco® in 1984, he started out sealing concrete floors in new data center spaces before the raised flooring went in. One day, when Ron showed up to look at a sealing job for a large Texas technology company, a man dressed in a suit approached him and said, “Can I help you?” When Ron told him why he was there, the man, Ed, asked him, “Do you clean floors too?” When Ron asked the executive about his needs, he learned that company required that the raised floor areas—both above and below the raised floor—be thoroughly cleaned before the company’s new computer equipment arrived. Ed had not been happy with the results—both in terms of quality and time—of the efforts of other folks so far. Ron said to the Ed, “Sir, you tell me what you want and by when and I’ll get it done.”

Ed was so amazed by the results of Sealco’s cleaning that he had Sealco clean the floors (above and below) two more times during construction before the computer equipment arrived. In fact, Sealco continued to provide on-going maintenance cleaning of that data center until it closed some 25 years later. That commitment to listening to customers’ needs and exceeding their desired results in terms of quality and time have been the hallmarks of Sealco services ever since. Over the years, we’ve added specialized cleaning of clean rooms, a number of specialty data center products, and Sealco’s own AirSeal® bypass airflow containment systems. Originally started in Dallas, TX where our headquarters is today, we now have locations in Atlanta and Houston and serve customers throughout the US and abroad.

Sealco’s Values

Employees First

One of the “Ronisms” (nuggets of wisdom from our founder, Ron Miglini) emblazoned on a wall here at Sealco is: “Sealco exists because of its employees.” Without well-trained, engaged, fulfilled employees who truly care about what they do, we can’t have satisfied customers. By making the development, training, growth, and success of our employees top priorities, Sealco has achieved a customer Net Promoter Score of 95 that is the envy not only of our industry, but of any industry.

Do The Right Thing

Sealco’s nearly 40 years of success is certainly a testament to the quality and value our customers place in our services and products. Equally as important, however, is the character of our employees and the over-arching belief that we must do the right thing—always. In all our dealings with our clients and employees, we strive for complete honesty, integrity, mutual respect, and professionalism.

Deliver Outstanding Results

Sealco is not—nor will it ever be—the lowest-cost solution. Our focus has always been on delivering the best results at the best value. Whether it be data center or cleanroom cleaning, hot or cold aisle containment, or data center products, our customers keep coming back again and again because they know we will make them look really, really good for choosing Sealco. The cleanliness of their facilities, the effectiveness of Sealco’s AirSeal bypass airflow containment, and the reliability of our products has earned us the lasting trust of our clients.
