Nothing good can come from a home that is not airtight. One reason a leaky home is not good is because of the bills. The HVAC system is on and running, then that temperature controlled air flows out of the home. Your HVAC system is killing itself and you are not in total comfort. Another reason a leaky home is bad is that critters can get into your home and cause damage. Another reason is that radon can flow into your air quality as well. What is radon? Radon is a gas that comes from the soil and is literally everywhere. There is always a little bit of radon in the outside air quality. That is alright, it is not ok when the radon gets into your home’s air quality. How can the radon get into your home and poison you? The radon comes in through cracks in your foundation. Radon can be in your basement. The radon comes in through the pores in your cement floor. Also basic entry points are gaps in walls, ceilings and doors. The radon can be anywhere too. The basement could have radon or even your attic. Most homeowners don’t know either. The radon is virtually impossible to detect and is extremely harmful. To fight against radon levels, get your home sealed properly. Redo those cement floors in the basement. Get the foundation fixed up. You don’t want leaks in your air ducts with your HVAC system. An airtight home is safer and also will significantly lower your bills overtime. There is no reason not to seal your home tight.
