Home Air Sealing
Air leakage or infiltration occurs when outside air enters a house uncontrollably through cracks and openings. The South Florida heat entering your home can cause increased energy bills. Proper air sealing your home can significantly correct this unwanted intrusion, with benefits such as:
- Reduced heating and cooling costs
- Improved building durability
- Healthier indoor air quality
We measure the amount of air intrusion before and after the repairs. The results are later compared. Don’t ignore air sealing for your home! Your home’s building envelop is as important to your home as the skin is to your body.
Duct Leak Sealing
In houses with forced-air heating and cooling systems, ducts are used to distribute conditioned air throughout the house. In a typical South Florida house, however, about 20 percent of the air that moves through the duct system is lost due to leaks through cracks, holes, and poorly connected ducts. The result is higher utility bills and difficulty keeping the house comfortable, no matter how the thermostat is set.
A duct system that is well-designed and properly sealed can make your home more comfortable, energy efficient, and safer. We warranty proper sealing of your home’s duct system literally measuring after repair or new installation with our duct blaster test equipment.
Where to Check for Air Leaks
A critical part of creating an energy envelope that keeps your home secure is making sure there are no leaks that allow air to seep out. While there are key parts of the home, like the attic, that can allow a lot of heat to come into the home, leaks can be just as counterproductive. The small amounts of heat that cracks allow to come in can amount to just as much as a larger area like the roof. But besides keeping the home from being efficient, air leaks can bring a host of other problems into the home, including:
- Allowing moisture to enter the home from the outside. This can lead to excessive wear and tear on the home structure, rotting of the home materials and mold or mildew growth.
- Allowing dust and allergens to come in from the exterior can contribute to allergies and other respiratory issues for the home’s residents.
- Allowing small pests to gain entry to the home, which can make it impossible to get them to leave. Ants, roaches, termites and other bugs can squeeze into small openings, and once they have found a way to come in, it is hard to get them to leave.
To properly seal your home, it’s important to have a qualified professional come into the home and assess the energy efficiency of the residence. A simple visual inspection is not enough to determine all of the areas that are leaking energy out of the home or allowing hot air to enter the home. By conducting a full energy audit, one of our technicians can help you find every part of the home that is leaking and resolve them.
Most Popular Spots for Air Leakage
According to the , there are quite a few spots in the home that can pose trouble when it comes to air sealing the house. Some of the most popular spots for air to escape or get into the home from the inside include:
- The attic, including the roof and the access point that connects the attic to the rest of the home
- Piping or duct shafts
- Dropped ceilings
- The section of exterior wall where staircase framing meets the wall
- The section of roofing that covers the patio or lanai
- Chimney and flue area
- Recessed lighting areas
- Windows and doors
- The wall separating two attached living spaces
The areas around windows and doors can be some of the biggest culprits when it comes to letting air leak in and out of the home. If you have older windows that make a rattling sound when the wind blows hard outside, chances are that you may need to get new windows or have them properly sealed to stop the air flow coming through into the home. Older doors that no longer reach the bottom of the frame properly can also allow a large amount of energy to escape.
Even Newer Homes Can Need Air Sealing
While some homeowners assume that only older homes need home air sealing, that is not always the case. There are times where a newer home can need to be sealed in order to keep it efficient. Excess wear and tear on the home can cause the weather stripping put in place to need replacement more often. In other cases, the caulk or other materials that were initially used to seal the home were low quality and end up wearing out faster than they should. Other homeowners find that the quality of the work on their home is lacking, and points where materials should touch are not properly connected. If you live in a newer home, but still have high utility bills, this can be a sign that you need home air sealing. Once the home is properly sealed, since it has been built with newer and energy efficient materials, you should see a large reduction in energy use.
