Our trained and knowledgeable staff is here and always willing to help.


What is your warranty on your work?

We offer a one year labor and materials warranty on all of our services. Some products carry a longer manufacturer’s warranty. For example, our sealed crawlspace carries a 20 year warranty. We stand by our work and will only use products by manufacturers that offer warranties on their products.

Do you offer a financing plan?

Yes. One year, same as cash, financing plan through an independent finance company. This is available for all of our services.

How far do you travel for a job?

Our crews can travel up to 100 miles from our office in Matthews, North Carolina.

We are open during the day--do you work nights and weekends?

Yes. As with most commercial customers we understand that all of our work will take place on nights and weekends. We also work on Holidays if needed as part of a plant shutdown.

We will have other work going on at the same time. How flexible is your work schedule?

We can alter our start and stop times to work around other contractors. Based on the service we are providing access to some areas may be limited or restricted (ie. mold removal).

I am building a new office building, do you do new construction?

Yes. Several of our services can be used just after construction is complete. We provide post construction cleaning of ductwork as well as Aeroseal air duct sealing as part of a LEED certification.

Air Ducts


How often should I have my air duct cleaned?

If you system has a filter located at the return grill we recommend cleaning your air ducts once every 7 to 10 years. If your filter is located at the unit then once every 5 to 7 years. Air ducts with filters on the unit typically accumulate dust and debris faster than those with the filters at the return grill. This is why we recommend more frequent cleaning for those types of commercial air duct services.

What type of filter should I be using?

When choosing a filter you want to play it safe. You want the filter to clean the air but not restrict the airflow. A MERV 13 pleated filter should work in most systems. Consult your HVAC contractor if you want to be more aggressive with your air filtration. We have a variety of filters available right here on our website on the home page.

We have a large air duct system. Will you clean up after each shift?

Yes. All desks floors and computer equipment is completely covered prior to the start of each shift. All plastic is removed and the floors are vacuumed at the conclusion of each shift.

Do you provide a written progress report?

Yes. You will receive a written scope of work for each shift for what work is planned for each shift and what work was actually completed. You will also receive a set of mechanical drawings that are updated nightly to show our progress.


How do I know if I need to have my cooling tower cleaned?

A visual inspection combined with your monitoring records compared to manufacturers designed performance is used to determine whether or not cleaning will help.

What will you use to clean our cooling tower?

We use an environmentally safe, ph neutral, probiotic cleaner. The cleaner is applied with the Blue Box next generation foam equipment.

Why do you use foam?

Unlike pressure washing foam will cause no damage to the fill of the cooling tower. Low pressure high density foam allows the probiotic cleaner to sit on the surface of the fill for an extended period of time. Dwell time is the key to a successful cleaning.

Will you come out and do a demonstration of your process at my facility?

Yes! We will come to your facility to do a lunch and learn for you and your staff. During the lunch and learn we can schedule a time to perform a limited cleaning of one of your cooling towers.

Is there an energy savings component to the cleaning?

Yes. On a commercial building in NYC it was reported that they saw a 30% increase in water flow in the tower. Bio film is the number one inhibitor of thermal transfer. By removing the biofilm you dramatically increase the efficiency of the tower.

Coil Cleaning Services & Optimization

How often should I have the coils cleaned?

The rule of thumb is once per year. If your system is used in an industrial application where heavy dust could become impacted on the coils you may want to look at doing a cleaning more often.

What makes your coil cleaning process different from other coil cleaning processes?

Most coil cleaning companies use harsh toxic chemicals that could damage or pit the coils such as acids. Our process uses certified green probiotics to remove the biofilm that inhibits thermal transfer and holds contaminants in the coil. Biofilm will also inhibit airflow which causes your system to work harder, run longer, and waste energy. Our probiotic cleaner poses no risk to our crew or the building occupants.

Can the probiotics harm the drain pan or drains?

No. Our probiotic will actually clean the drain pans and lines. This is an added benefit to using the probiotics.

Removing Scale From Cooling Tower Fill
Commercial Dry Ice Blasting Services


What is dry ice blasting?

Dry ice blasting is similar to sand blasting, plastic bead blasting, or soda blasting where a medium is accelerated in a pressurized air stream to impact a surface to be cleaned or prepared. But that’s where the similarity ends. Instead of using hard abrasive media to grind on a surface (and damage it), dry ice blasting uses soft dry ice, accelerated at supersonic speeds, and creates mini-explosions on the surface to lift the undesirable item off the underlying substrate. We have a video showing dry ice blasting on our video page.

What is the difference between dry ice blasting and other mold removal techniques?

Dry ice blasting has many unique and superior benefits over traditional cleaning methods as other cleaning methods can be toxic.

  • • Sand, soda, or water blasting can leave toxic secondary waste to be cleaned up in addition to the toxic substrate
  • • Sand, soda, or water blasting can create downstream contamination that effects surrounding installations
  • • Soda blasting can kill surrounding vegetation
  • • Chemical and solvent cleaning methods are toxic, which creates toxic waste to be disposed of
  • • Workers are exposed to potentially harmful substances through the use of chemicals and solvents

Is dry ice blasting safe and effective?

Yes! Dry ice blasting is clean and safe.

  • • Dry ice is an approved medium by the EPA, USDA & FDA, and is non-toxic, non-hazardous and inhibits mold & bacteria growth
  • • Dry ice blasting has been effectively used in EPA, USDA, FDA, AIB and GFSI inspected/certified facilities
  • • Dry ice blasting is safe to use with food processing equipment
  • • Dry ice blasting does not release harmful gases into the atmosphere
  • • Dry ice blasting does not generate secondary waste
  • • Dry ice blasting is safe and non-toxic (once particles impact the surface they dissipate into the atmosphere)
  • • Dry ice blasting reduces or eliminates employee exposure to (and corporate liability from) the use of dangerous chemical cleaning agent

What is AeroSeal?

Aeroseal is a revolutionary technology that allows us to seal the ductwork from the inside out. Unlike mastic and tape we can seal leaks that cannot be seen by a visual inspection.

My ductwork is behind walls and fixed ceilings. Can you still seal it?

Yes. Our system works much like fix-a-flat. We pressurize the duct system and then inject an environmentally safe sealant that only sticks to the holes as the air is trying to escape.

What if I have large holes in the ductwork? Can you still seal it?

Aeroseal can seal up to a 5/8 inch hole in the ductwork. As long as we have access to the ductwork we can fix holes larger than 5/8 on an inch.

Are there any tax incentives for Aerosealing the duct system?

Yes we have a link on our website that will allow you to look up the different rebates available for you area.

Can you seal our exhaust systems as well or is this just for HVAC systems?

Yes we can seal the exhaust system. You will get the biggest return on investment from the sealing of the exhaust systems. Exhaust systems tend to leak much more than the ducts for your HVAC system.

Does Aeroseal work on insulated ducts and flex ducts?

Aeroseal will on any type of ductwork. Flex, metal, lined, or duct board.

Do I need to clean my ducts before you seal them?

No. We recommend duct cleaning prior to sealing but it will not effect the Aeroseal process.
