Proper Partnership: Tips For The Business Registration and Operation

When my best friend approached me with this new business opportunity, I decided that it might be fun to work together as partners. What I didn't realize was how complex partnerships could be. Not only was there the daily task distribution and conversations, there was a lot of paperwork to be filed for the business to be legal, and partnerships need to be registered specifically. I created this blog afterward to help illustrate the process and offer tips for others who are considering their own business. If you're looking to be an entrepreneur or start a partnership, I hope the posts here help you get things started.


3 Types Of Residential Radon Mitigation Systems

Radon is a radioactive gas that is produced naturally as uranium in soil, rocks, and water is broken down. Modern homes can become a haven for radon gas due to the pressure differences between a residential building and the soil below.

Exposure to radon has the potential to cause lung cancer and other serious health conditions. You can reduce your family's risk of illness by installing a radon mitigation system in your home. 

1. Soil Depressurization

Soil depressurization is the most common type of radon mitigation used in a residential setting. You can choose between an interior and exterior depressurization system design when working with an experienced contractor. The only difference between the two is the location of the pipes that transfer radon from the soil to the atmosphere.

With an interior depressurization system, a network of pipes is installed throughout the walls and closets of your home. The pipes are hidden from view and connect to a specialized fan in your attic. Alternatively, an exterior depressurization system relies on pipes that are installed outside your home. Both approaches can be effective in reducing radon levels inside your home.

2. Slab Depressurization

The slab depressurization method of controlling radon is best suited for homes that are built atop a concrete slab. An experienced contractor will drill a hole all the way through the slab foundation. A PVC pipe will then be inserted into the hole and routed to your home's roof. This pipe allows excess radon to escape safely into the atmosphere above your home where it dissipates quickly.

The exhaust pipe for a slab depressurization system can be placed in an inconspicuous location or painted to match your home's exterior if you want to preserve the curb appeal of your property.

3. Crawlspace Depressurization

Radon generally finds its way into your home because the indoor air pressure is typically lower than the air pressure in the soil. Crawlspace depressurization works to reduce radon transfer by lowering the air pressure within the crawlspace below your home.

A specialized fan draws air out of the crawlspace and directs it into a PVC pipe that is routed to the roof of your home. Any radon gas that is released by the soil in your home's crawlspace is safely transferred along with the air moved by the fan. 

If you want to minimize your family's risk of developing lung cancer or other serious illnesses, installing a radon mitigation system in your home is a must. To learn more, contact a radon mitigation service.
