Why thermal imaging before bid?
We walk every project with an IR camera before quoting. It takes 20 minutes and eliminates the three most common callback causes.

Blower Door & Diagnostics

We run a baseline blower-door test before a single can is opened. ACH50 recorded, primary leakage sites mapped with smoke pencil and IR.

Process Timeline
What you receive at project close
  • Pre- and post-install ACH50 blower-door certificates
  • Thermal IR photo documentation set
  • R-value log by assembly zone
  • Vapor barrier inspection sign-off

Why contractors add us to their list
Documentation-first
Every install ships with before/after ACH50 certs, IR photo sets, and a signed R-value log. Your GC file is complete.
Zero callback record on closed-cell
We attribute this to the diagnostic protocol. We find the problems before application, not after.
Scheduling built around your sequencing
We work around framing inspections and insulation rough-in windows. We don't hold up your close-in.

“They’re the only sub I don’t have to babysit. The documentation package they deliver is better than what most GCs produce themselves.”
