Our Scope

What We Won't Do

We install passive fire systems and manage passive fire compliance. That's it.

We don't subcontract work we haven't personally approved, and we don't install a product that isn't specified for the application it's going into, even if it's cheaper.

If a job needs a different trade, we'll tell you rather than quietly stretch our scope to cover it.
