Your energy bills are higher than they should be. The crawlspace was "done" years ago but something still doesn't feel right. You called someone out, they glanced in the attic from the ladder, and told you everything looked fine.
It wasn't fine.
The problem with most insulation contractors isn't that they do bad work — it's that they don't look hard enough to find the real problem. A quick visual doesn't tell you where conditioned air is leaking out, where moisture is hiding, or where decades-old insulation has settled and failed.
For that, you need someone willing to crawl all the way in and actually look — and the diagnostic tools to see what the eye can't.
That's what we do.
