How can I tell if my foundation has been waterproofed?
A: You can go to any exterior foundation wall and dig down about one foot. If you do not see a black paint like substance or a plastic barrier, then you do not have waterproofing.
How does a French Drain work?
A: A French drain is placed along the foundation wall next to the footer on either the inside or outside of the foundation wall. French Drains are designed to carry water away from the foundation wall to a low spot in the yard or to a sump pump located in a low spot in the crawlspace or basement.
How do you determine whether to put the drain on the inside or outside?
A: Ease of access and cost feasibilities are what determine the location of the drain in your home. If you have heavy landscaping or amenities such as walkways, outdoor furniture or decking around the foundation of your house the access to the wall can become difficult and costly. In this case we would recommend putting the drain on the inside on your home.
What is the warranty on the sump pump?
A: Manufacturer’s warranty for the sump pump that we use is three years.
RADIANT ATTIC BARRIER
Where does the radiant attic barrier go?
A: The attic barrier is installed on the knee wall and the butt ends of roof rafters in your attic.
What will be the temperature reduction in the attic once the barrier is installed?
A: Average temperature reduction will be between 30-50 degrees Fahrenheit.
How much will this lower my energy bills?
A: After installation of the attic barrier you will see a 10-15% reduction in your monthly energy bill.
Do I still need attic insulation if I install a radiant barrier?
A: Yes. During the winter you want to capture the radiant heat and keep it in the home. The attic is not an occupied space so you want to keep the cold temperatures from affecting the temperature of the drywall on your ceiling.
Will I regain the use of my attic for storage?
A: Yes. The lowered temperature of the attic makes it ideal for storing items. There is will be no damage to items stored due to excessive hot or cold air entering the attic.
ATTIC INSULATION REPLACEMENT
What is the current code for blown in attic insulation?
A: R38. What does that mean? According to energystar.gov, Insulation levels are specified by R-Value. R-Value is a measure of insulation’s ability to resist heat traveling through it. The higher the R-Value the better the thermal performance of the insulation.
Does blown in insulation create a dust problem in my house
A: Yes. But we can fix it. Some blown in insulation create dust. Mostly linked to pressurization problems in the house. Gaps around the can lights and pipe chases, penetrations can allow insulation fibers to be dragged into your house as air flows from attic to the house. To solve this problem we can air seal your attic as well as fix your pressurization problem.
Roughly how many inches equal R-38?
A: Insulation depths vary by type and manufacturer of the insulation. The average for depth is 16 inches
When do I need to replace my attic insulation?
A: There is no report saying that attic insulation needs to be replaced after a certain number of years used. If insulation becomes damaged from moisture problems or animal infestation problems, then we recommend changing the insulation immediately. You would replace the insulation if it becomes compressed.
Is it a good idea to seal the attic access door?
A: Yes. The attic access door allows hot air from the attic to enter to occupied space in the summer months and cold air to enter the occupied space in the winter months. Driving up both heating and cooling costs. Sealing this door will eliminate that problem.
DRY ICE BLASTING
What is Dry Ice Blasting?
A: 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?
A: Dry ice blasting has many unique and superior benefits over traditional cleaning methods 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?
A: 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
Can I be in the house while you are blasting?
A: Yes. Using Dry Ice Blasting in the crawlspace does not deplete any oxygen or create any discomfort in the home while.

What is the difference between a vapor barrier and a sealed crawlspace?
A: Vapor barrier is a 6-10 mil polymer only applied to ground, the seams are over lapped but not sealed, and the vents remain open. A sealed crawlspace uses a 15 mil 3 layer fiber reinforced polymer, applied to ground, walls and piers. We overlap polymer and tape seems with water resistant tape. Vents are sealed with an insulating foam board and all penetrations to the outside are caulked to prevent air and moister infiltration. A dehumidifier is installed once crawlspace is sealed to control relative humidity.
Why do the vents to the crawlspace need to be sealed?
A: Leaving vents open allows warm humid air into the crawlspace. Humid air interacting with cold surfaces in crawlspace can lead to mold and moisture problems.
Will a sealed crawlspace solve my mold and moisture issues in my crawlspace?
A: Yes. A properly installed sealed crawlspace will eliminate the two main contributors to mold and moisture problems. Sealing the vents eliminates the humidity and covering the ground eliminates ground moisture.
What are the benefits of sealing my crawlspace?
A: Sealing your crawlspace improves the energy efficiency of your heating and air conditioning system and improves indoor air quality. It will also increase the resale value of your home.
Is there a crawlspace too low to seal?
A: Yes. Your crawlspace must be at least 24 inches high. Anything lower than that will make it impossible for our crews to work in.
Can I use my crawlspace for storage once sealing is complete?
A: Yes. By controlling the relative humidity and temperature of the crawlspace you create a usable storage area the size of the first floor of your house.
