How do we air-seal ?

Our attic air sealing service focuses on identifying and sealing air leakage points in your attic, which can lead to significant energy loss and decreased home efficiency. Our experienced team will meticulously inspect your attic for gaps, cracks, and openings, ensuring a thorough sealing process to prevent air movement and moisture buildup. By professionally sealing these areas, we enhance your home's overall comfort, energy efficiency, and reduce heating and cooling costs.

Top air penetration points

Top Plate & Voids

Air leakage points are commonly located along the outer perimeter of the attic and where walls in your living space meet the attic. These areas, such as the gap between the 2x4 top plate and drywall, allow significant air escape. To effectively seal these gaps, spray foam insulation is the recommended solution. An interesting fact to consider is that when cool air leaks into a humid, hot attic, it can lead to issues like condensation, damaged insulation, mold growth, and wood rot.

Can/ Recess Lights

Can lights often exhibit noticeable air leakage gaps, to the extent that light can be observed from the living space in the attic. Our approach involves sealing these gaps using a combination of caulk and a foam board cover. Recessed lights require extra caution since they are typically not IC rated due to the heat they generate. To address these penetrations, we either replace the lights with IC rated ones or utilize a rock wool cap, which offers fire retardant properties and an additional insulation layer around the recessed light penetration.

Chimney/ Flums

When air sealing a chimney or flue, we employ a combination of techniques. First, we use high-temperature caulk or sealant to seal any gaps or cracks between the chimney or flue and the surrounding structure. Then, we install a chimney cap or flue damper to further prevent air leakage and improve energy efficiency.

HVAC Duct Boots

Sealing duct leaks is crucial for maximizing energy efficiency, as the average home can lose 20-30% of HVAC energy through these leaks. By addressing gaps around duct boots with Great Stuff spray foam, we effectively prevent conditioned air from escaping into the attic and unconditioned air from entering the living space.
