Automobiles have designed air intakes to allow for ventilation, air flow and climate control. These designed air intakes are located at the lower windshield area, inside the cowl plenum chamber. These air intakes are located specifically to access relatively clean air for usage inside the passenger compartment.  Most of today’s vehicles have cabin air filters typically located behind the glove compartment or under the hood or dashboard. Its job is to filter all of the air that comes through the car’s HVAC system to prevent pollutants, such as dust, pollen, smog and mold spores from entering the passenger compartment.  Follow Manufacturer’s recommendations for cabin air filter replacement to prevent excess dust and mold from entering the vehicle found in your owner’s manual or check with your service professional.

There also can be undesigned air intakes (body-faults). These undesigned air intakes, if located in an area of negative pressure on the vehicle’s perimeter can cause significant dust intake. Most dust leaks occur at lower and rearward vehicle locations. Dust leaks are common in rear wheel housings and the lower door sill areas. In these wheel housings exists an area of high pressure resulting from the forward motion of the vehicle causing a vacuum action inside the vehicle that pulls air and dust into the vehicle. The air that is pulled into the vehicle typically leaks out of the vehicle up high and the resulting dust settles low.  This is due to the pressure differences created above and below the vehicle while it is in motion. The road dust that is lifted by the negative air pressure under the vehicle enters the rearward wheel housings and is simply pushed into the vehicle. Almost all dust leaks occur at lower and rearward locations. Dust leaks leave a trail at the entry point that is either cone shaped or slit shaped.  These trails can help locate the source of the dust leak.

Dust in a vehicle can cause serious health effects from the inhalation.

Dust in vehicles can harm various modules and electronic components located in the rear of the vehicle that could result in thousands of dollars in electrical/electronic repairs or compromise various safety components of the vehicle such as seat belts or air bags.

LEAKPRO® technicians are specifically trained to eliminate dust leaks.

After having my 2016 Buick Lucerne repaired unsuccessfully 6 times by my GM dealer I heard of LEAKPRO. I called LEAKPRO, John came out and had my car fixed in 1 hour. The front sunroof drain tubes from the factory were actually trapped at the dashboard. John installed two new drains and I have never had another leak!

My LEAKPRO representative Jesse did a great job fixing an intermittent water leak that would wet the back seat of my new truck. Jesse quickly pinpointed the problem and fixed it. No leaks now! Great service!

K. Peters VancouverBC

I had an ongoing issue with a leak in my 2017 F150 from under the left side dash. My Ford dealer could not pinpoint it after 4 times. The dealer finally called in LEAKPRO and the leak was resolved within a couple of hours. We have had a lot of rain, and no more leaks! LEAKPRO knows what they are doing!

D. Wiley HamiltonOntario

I had a musty smell in my used car I had recently purchased. MY dealer called in LEAKPRO, and it was determined that the smell was due to a water leak. LEAKPRO fixed the leak, replaced all l the under pad and disinfected the flooring. My car smells great and no more leaks!

I had a big water leak in my brand new truck on the right side. I was so upset, my carpet was soaked! My Service Advisor said not to worry we use LEAKPRO. I received my vehicle back at the end of the day as promised, I felt the carpet it was dry! I lifted the carpet to check underneath and it was dry, all new under pad and fresh smelling. My service advisor informed me it was a skip in the sealer from the factory. I am so happy I had to write!

I had a wind noise on my brand new Charger that my dealer after two attempts could not figure out, it was driving me crazy. I went to another dealer and they said no worries we bring in an outside specialty company. I arrived at the dealership for my appointment as I wanted to drive my car with the technician so he could hear what I was experiencing. Steve from LEAKPRO said he knew what the issue was and had it fixed within an hour!!! THANK YOU LEAKPRO!
