Why Choose Spray Foam?
Spray foam insulation is a high-performance solution that helps improve energy efficiency, indoor comfort, and overall building performance. As it expands on application, it seals gaps, cracks, and hard-to-reach spaces, helping reduce air leakage and create a tighter, more efficient building envelope.
Because it combines insulation and air sealing in one application, spray foam helps reduce drafts, improve temperature consistency, and support long-term performance in both residential and commercial spaces.
Where Does Spray Foam Work Best?
Spray foam is commonly used in areas where air leakage and heat loss are most likely to occur, such as walls, ceilings, rim joists, crawl spaces, and other difficult-to-insulate areas. It is especially effective in spaces where both thermal performance and air sealing are important.
Whether used in new construction, renovations, basements, additions, or garages, spray foam is a strong choice for improving comfort, efficiency, and overall protection.

Attic
Blown-in insulation tops up existing attic insulation without major disruption, settling around framing, corners and uneven areas. Batt insulation fits standard joist spaces in ceilings.
How we fix it
Exterior walls
Spray foam expands as it’s applied, sealing gaps and cracks to help reduce drafts and air leakage. In framed walls, batt insulation fits standard stud spaces for dependable thermal performance.
How we fix it
Rim joists
Rim joists are among the areas where air leakage and heat loss are most likely to occur. Spray foam combines insulation and air sealing in one application.
How we fix it
Basement walls
Basements can account for about 25% of a home’s total heat loss. Spray foam is a strong choice for basements, combining insulation and air sealing in one application.

How we fix it
Crawl space
Spray foam is especially effective in hard-to-insulate spaces like crawl spaces, where thermal performance and air sealing both matter. It expands to seal gaps and cracks, helping reduce air leakage.
How we fix it
Old insulation
Over time, insulation can become compacted, damaged or contaminated, and its performance can decrease. We remove it with industrial vacuum systems so the space can be inspected and prepared before re-insulating.
Older materials such as vermiculite may require testing or a specialized assessment before removal, due to the potential presence of asbestos.
