"Before and after" here means real, credited project footage — energy performance, air sealing, and visible retrofit outcomes. Not fabricated case studies, not CCA's own projects.
An attic retrofit is one of the most visually dramatic spray foam transformations — loose or compressed batt insulation gets replaced with a continuous, air-sealed foam layer.

Crawl space encapsulation pairs a vapor barrier with spray foam on the rim joists and sometimes the perimeter walls — the change from a damp, vented crawl space to a sealed one is one of the clearest before/afters in the trade.

Retrofit injection foam is applied to existing, already-finished walls through small drilled access holes — the transformation happens inside the wall cavity, not on the surface, which is why the before/after is usually about performance rather than appearance.

Roof deck spray foam moves the insulation and air barrier to the underside of the roof deck itself, converting a vented attic into a semi-conditioned space — a structural and thermal change you can see in the finished footage.

A retrofit changes how a home performs. It doesn't automatically change every question a future buyer, appraiser, or inspector might ask. Here's the honest version.
Air leakage is reduced, comfort in the treated space usually improves, and energy use associated with that space can go down. In roof deck and crawl space conversions, the assembly itself changes — a vented space can become a semi-conditioned one, which affects things like duct placement and moisture behavior going forward.
Some home inspectors flag spray foam simply because it hides the roof deck or wall sheathing from direct visual inspection for leaks or rot — that's a documentation issue, not a defect. Keeping records of who installed the foam, when, and to what specification is the practical way to address it if the home is ever sold. This is a factual, general note, not insurance or legal advice.
