Air Sealing

Air-Sealing leaks in your home is a must for controlling comfort, improving indoor air and reducing your heating and cooling costs. 

If your home was built before 2015, it could be 3x as leaky as a new home! Many homes we test built before 1980 are 3-10x as leaky! Those are serious losses!

Air-Sealing reduces the movement of heated and cooled air from the inside of your home to the outdoors through gaps, cracks, and penetrations you never see. These penetrations exist around plumbing pipes, electrical penetrations, recessed lights, HVAC systems and the "top plates" of your interior and exterior walls.

FLC Energy's technicians are trained to find and seal these hidden leaks. Air-Seal leaks in your attic, basement and crawlspace is critical to making you home's insulation effective. Air-Sealing reduces improves humidity control, stops uncomfortable drafts, lowers utility bills, cut down on pests, AND improves your indoor air quality. Needless to say, its extremely important!

How Do We Find and Assess Air-Leakage?

A Blower Door Test, Diagnostic Testing and an Infrared Camera.

 We encourage homeowners to use our equipment with us too!  After all, thats the best way to learn.

This is a Blower Door Test. This test verifies how leaky or tight a home is and can be used to double check all the work performed by a BPI Accredited Home Performance Contractor.



Air-Sealing Attics

Since heat rises, Air-Sealing the attic is the first place we start. We target holes and penetrations in the ceiling, attic-access, lighting fixtures, fans, plumbing bypasses, wiring, and chimney chases. All of FLC Energy's work is verified with a post-work Blower Door test. 

This is a top-plate with electrical penetrations running through it. This top-plate is located above a hallway.



Air Sealing Basements

Basements can be a major source of outside air infiltrating your home.  We focus on sealing rim joists (band boards), foundation walls and sill-plates to create a basement that keeps your home warm, dry and comfortable. We also seal the floor of your home to stop harmful air in this area from contaminating your living space. 

 

Crawlspace Air-Sealing, Encapsulations and Conditioning the Space

 

This is a "Pan-Joist Return" for an HVAC system in a Crawlspace. This system has come apart and is pulling air from the crawlspace directly into the HVAC system and sending it into the home. This is extremely common in home with HVAC systems in the crawlspace.

Whether you experience standing water or not, crawlspace moisture diffuses through your home by air-movement, fostering the growth of mold, creating uncomfortable spaces and creating poor indoor air quality.

 

Here’s what you can expect: From the attic to the crawlspace, inside and out, FLC can locate and seal Air-Leaks throughout the home. We'll also Test-In and Test-Out before we leave, proving the difference we've made, right before your eyes.
