Air Sealing

Stop money leaking from home

Air Sealing benefits cost nothing

There are many benefits to air sealing, but perhaps the best reason to get your home sealed is that you don’t need to pay for it! With our Mass Save home energy audit, we are able to air seal your home at no cost to you. So enjoy these benefits below at no expense!

Lower energy bills

Air leaks can be responsible for wasting significant energy, so by sealing them up you’ll be looking at significant savings.

Increased Comfort

Air leaks are the source of drafts in a home. So sealing up those cracks and holes will make rooms cozy again to be in.

Improved Air Quality

When a home is sealed, it's less vulnerable to air born pathogens, humidity, dust, pests, and other unwelcome outsiders.

Stronger Durability

Moisture leaked into a home leads to mold which can damage property and be harmful to health.

A home’s air leaks can result in the same energy loss....

.... as a window open all year round.

What is air sealing?

Caulking & weather stripping

Air sealing involves plugging in the cracks where air is leaking from the home. We use caulking and weather stripping to provide a seal around windows, doors, pipes, and any other holes leaking air to the outside. 

For maximum sealing of air leaks, let a professional energy specialist tackle the job. Neeeco knows all the nooks and crannies where energy escapes, and we know how to fill them in. 

Where are the Leaks?

Up to 30% of energy lost to drafts

Sources of air leakage are an artifact of normal home construction. Thousands of pieces from big to small are joined together in assembly, and where they meet likely has some clearance space around the joint. By the time the house is complete, there are leakage points all over the place.

As much as 30% of the energy is lost in process due to leaks in the ducts, causing HVAC systems to work harder to generate the desired heating or cooling.

Basements Air Leaks

Sitting on the foundation is the house’s frame with its numerous joists bolted together. But where they meet arises small cracks that over time expand in size with the warping of wood. Then there are the gaps that result from holes drilled to accommodate lines for water, electrical, plumbing, and fuel along with dryer and stove vents. Together these vulnerabilities fill the basements with enough holes to suck in external air, leaking energy to the outside.

Attic Air Leaks

Sealing the attic is an important first course of action against air leakage. This is because rising heat forms a convection current that draws air into the attack and then out into whatever holes exist. As this vertical transport of air move up, it draws air from below, creating a negative pressure that sucks in outside air through leaks. So by sealing the attic, the heated air is not allowed to escape, which then stops the upward airflow from transferring energy out of the house.
